Description

[0001] The present invention relates to a method for making a phase change insulation material,

The present invention relates to a fabric comprising a thermal insulating material (a concept including a thermal insulating material and a broad insulating material) capable of absorbing or releasing thermal energy using a phase change material to maintain the temperature of the object at a specific temperature range different from the surrounding environment, And more particularly, to a thermal insulation material fabric which can be manufactured to have various shapes suitable for an object to be insulated through processing, a manufacturing method thereof, and an apparatus suitable for manufacturing the same.

The term " insulating material " generally refers to a material used to maintain the temperature of the object at a constant temperature range different from the ambient temperature, and various materials can be used for thermal insulation. However, (Or absorbing) heat to and from the object to thereby maintain the temperature at a constant temperature by replenishing the heat absorbed by the object in the surrounding environment A thermal insulation material may be used.

On the other hand, phase change materials (PCM) are conventionally referred to as materials that have a latent heat of practical use and are convenient and readily available where heat energy release and absorption are required. That is, the phase-change material generally refers to a material which is widely used for industrial purposes because it has a large latent heat to enter and exit from phase transformation and has a larger heat release or heat absorption per unit mass than other materials.

Hereinafter, in the present invention, a 'thermal insulation material' is a phase insulation type thermal insulation material that can supply a large amount of heat per unit mass to other materials using phase transformation phenomenon, particularly a phase transformation type coolant material referred to as an " ) Will be mainly referred to.

Phase-change insulation is not used in recent refrigeration facilities but is widely used for preserving and transporting incompatible materials such as fresh food, biomaterials or medicines, and for workers, outdoor hobbyists Cold vests and warm vests for body temperature management.

Therefore, there is no such thing as electricity, there is no insulation equipment, and in a mobile environment, a lot of materials that make up a thermal insulation material to form a thermal insulation material that can heat in various forms to suit the environment and use more efficiently Material structure and manufacturing method are being studied and developed.

Recently, a lot of researches and developments have been made on a high-efficiency insulating material which can be applied to a wide variety of applications by increasing the workability among the insulating materials, reducing the weight and volume.

However, the phase transformation type thermal insulation material is often formed with a material other than a material to form a product that can form a composite material to give a proper function, rather than a product itself. The advantage of this composite material is that it can combine the properties of phase-change insulation with the properties of other materials to enable it to respond effectively to a given temperature condition and environment.

For example, composite materials that can withstand high temperatures can be used in a variety of fields such as social public areas such as firefighting, flame retarding of defense industry, heat insulation fields, eco-friendly thermal insulation fields, and various other industrial thermal insulation materials.

Recently, the interest in the production and application of PCM materials, which can be used alone or in combination with insulating materials to provide excellent warming effect, in relation to functional clothes such as outdoors and functional clothes, is becoming more of interest.

On the other hand, recently, as a material used for a human body, for example, a high thermal insulation effect is required in using an outdoor thermal insulation composite material. However, there is a problem that sweat is lost due to inability to discharge moisture in the body, It is difficult to apply the composite material including the phase change insulation material to a variety of applications because there is a problem that the material is stiff and the fabric is not suitable to be made into a cloth. It is a reality that the material is used very limitedly.

In addition, when used as an industrial material, when a phase-change material is bonded to the entire surface, the solid gel-like material itself is not soft and has a somewhat rigid property, so that the workability is low. It can not be flexibly bent, stretched, and relaxed, and can not have form flexibility.

When the phase change material is a liquid phase, it may be solidified at a set temperature in a state where the shape melts and melts between normal protective films, so that the thermal insulation product itself may not be maintained.

Korean Patent Application 10-2016-0125610 Korean Patent Application 10-2016-0103564 Korean Patent Application 10-2010-0022562 Korea patent application 10-2012-0105663 Korean Patent Application 10-2010-0058382 Korean Patent Application 10-2010-0018301

The present invention is to overcome the problems and limitations of the conventional heat-transforming material composite material, such as the above-mentioned conventional phase-change material composite material, and to improve workability in the fabric state in spite of the rigidity in the cured state of the material or the heat insulating material, It is an object of the present invention to provide a thermal insulation fabric having a structure suitable for various merchandise production and having a structure capable of flexibly forming a shape suitable for an object in a commercialized state to enhance the merchantability, a manufacturing method thereof, and an apparatus suitable for the same.

According to an aspect of the present invention, there is provided a thermal insulation material fabric having a good heat retention efficiency at the same time as the processability, having a structure suitable for ventilation and discharging moisture, .

The present invention is characterized in that a phase transformation type thermal insulation material is filled in a desired pattern through a manufacturing process in which various types of processable thermal insulation material layers are arranged in a plurality of irregular patterns or in the form of respective cells in a form of cells, And the peripheral edge portion of the filling portion is made to be able to be more firmly fused and attached by emptying the insulating layer.

According to the present invention, when an object to be exposed to heat and heat is occasionally brought into contact with the object, an edge of the edge forms a single air layer, thereby enhancing the effect of heat insulation.

The present invention allows the insulating material to be evenly distributed over the entire fabric so that the object can be kept warm evenly.

To achieve the above object, the present invention provides a heat-

A plurality of unit pieces formed by laminating a heat insulating material made of a phase change material in a state of being spaced apart and having upper and lower surfaces covered with a plurality of unit pieces spaced apart from each other, There is a portion where the outer cloth or sheet overlaps without a heat insulating material, and in this region, there is a portion where upper and lower outer shells or sheets are tightly fixed to each other so that a unit cell space in which these unit bodies are located is divided, So that the AC movement of the unit body is restricted between the spaces.

The area where the insulating material exists in the fabric of the present invention may be 50% to 99% of the total fabric area. If the ratio of the area of the insulation material is small, the effect of thermal insulation is deteriorated. On the contrary, if it is too much, it becomes difficult to have a space necessary for cutting, sewing and other processing when making a product by processing the fabric.

The selection of the phase change material allows the phase change insulation material of the present invention to be made in consideration of the phase transformation temperature that is appropriate for the function of the product to be used. If it is difficult to match a proper temperature range with one phase-change material, it is possible to mix two or more phase-change materials having different phase transition temperatures, which are different from each other, to form a phase-change material insulator.

In the present invention, the areas for separating the unit pieces from each other may be provided with pores (fine holes) for moisture permeation through which the ventilation or moisture is discharged in the fabric of the phase change material insulator through the outer cloth or sheet.

In the present invention, the outer cloth or sheet (the concept including the laminating sheet as the case may be) is made of a flexible and stretchable material in bending as compared with a thermal insulating material.

In the present invention, the spacing between the unit bodies, that is, the region where the phase change material insulating material is not present may be provided with both the laminating sheet and the outer cloth or sheet, or may be provided with only outer cloth or sheet.

In the process of forming the present invention, the upper and lower laminating sheets in the area where only the laminating sheet alone is insulated can maintain fusion or adherence with each other. The laminating sheet is usually a synthetic resin sheet such as a polyethylene sheet, a polypropylene sheet, But is not limited thereto.

In the above, the unit body refers only to the form in which the phase change material is kept between the upper and lower lamination sheets, but the phase change material is insulated from the phase change material by a non-permeable sheet or film and overlapped between the upper and lower lamination sheets . ≪ / RTI > At this time, the heat insulating material may be made of beads, powder, airgel or the like in a dry state by impregnating the substrate, and the space having the heat insulating material may be a vacuum space.

According to another aspect of the present invention, there is provided a method for manufacturing a warm-

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

Fig. 1 is a plan view of the raw material of the insulating material of the present invention, and Fig. 2 is a front sectional view of the raw material of the insulating material of the present invention.

Here, the raw material of the thermal insulation material is formed to have a predetermined width, and a plurality of circular unit pieces (laminating unit 210) are arranged in the longitudinal direction and the width direction in the thermal insulation material. These circular units are formed by laminating sheets of the phase change material insulating layer 110 on upper and lower sides of the phase change material insulator 110. In the periphery of the laminating sheet constituting the circular unit body, phase change materials forming the insulating layer 110 are separated from the sol state So that the sealing portion 213 is formed. Of course, the laminating sheet is made of a material that can not permeate through the phase change material in the sol state. The circular unit body 210 does not move freely within the thermal insulation material fabric and the seaming line 330 is formed so as to maintain a constant arrangement and distribution density on the outer cloth 300 or sheet covering the circular unit body up and down.

In this case, the unit body includes only the phase change material insulating material between the upper and lower lamination sheets. However, the phase change material insulated material is not shown here together with the phase change material insulating material. The upper and lower lamination sheets may be stacked in a unit shape.

Fig. 3 is a schematic view showing a schematic and a schematic view of the flow and condition of the apparatus for forming the raw material of the insulation material and the elements constituting the raw material before the seam line is formed.

First, a cutting section is provided at the preceding part of the apparatus. In the cutting part, the phase change material forms a flat plate with a constant thickness in a gel state and is rolled in a roll 11 state. The phase change material prevents the layer and the layer from sticking to each other in the roll state. For this purpose, prior to forming a phase change material plate, a thin polyethylene or other polyolefin film is laid on the bottom, and a phase change material plate is formed thereon, so that a film is interposed between the layer and the layer when the roll state is formed, The release agent material may be applied, or both of these films and release agents may be applied.

As a more specific example, such a phase-change material roll may be formed by, for example, placing a polyolefin film on the bottom of a phase change material plate, placing the phase change material having fluidity thereon, spreading the phase change material to a predetermined thickness, After the gelation is further advanced, the release agent material may be applied thinly on the surface thereof and rolled into a roll state. Of course, when making the roll, the phase-change material gel should have adequate fluidity and elasticity to be able to be formed into a roll.

In a further alternative embodiment, the phase change material roll may be made by impregnating a nonwoven fabric or woven fabric first with the impregnating substrate and then impregnating the film with a certain amount of phase change material having a high flowability and close to the sol state, And then the upper surface thereof is spread to a predetermined thickness using a mechanism such as a roller to form a flat plate. Then, as in the previous embodiment, the phase change material is further gelated, the release agent material is thinly coated on the surface thereof, It is possible.

The heat-insulating material roll 11 thus formed is provided on a heat-insulating material roll holder, and a press cutter is provided at a next position on the process stream to form a plurality of insulation material objects by cutting the heat-insulating material roll into a sheet material. The upper portion of the press cutter is composed of a roller-shaped metal mold 13 shown in Fig. 5 in which a cutter blade is formed on its surface. The lower portion of the presser cutter is made up of a flat support base plate 100 (see Fig. 8A) (15).

In the cutting part, the roll type heat insulating material is loosened and moved from the support frame 15 to the next step in the form of a flat plate material. In the course of this process, the upper roller 13 is rotated, Is cut and cut by pressing the heat insulating plate material as shown in FIG. 8 (a) to obtain a state as shown in FIG. 8 (b). In this case, a plurality of entities 110 made of a heat insulating material and the remaining residues 120 on the outer side are separated by cutting lines, and the plurality of entities 110 have a certain arrangement of repetitive patterns.

According to the embodiment, a plate-shaped mold 12 'as shown in FIG. 4 in which a cutter blade of a repeated pattern is formed on the flat surface instead of the roller-shaped metal mold 13 may be used. In this case, the heat insulating plate material 100 is not continuously processed, but the predetermined length of the raw material is progressed to be placed on the support frame, the mold 12 'is lowered to cut, The cutting can be done while the step-type progress is continued and stopped.

6 is a cross-sectional view showing one embodiment of the configuration of a mold.

In FIG. 6, the upper end of the main body 12a 'of the plate-shaped mold 12' is formed of a flat plate, and a cutter blade 12b 'having a predetermined pattern is formed on the underside thereof. Between the blade and the blade, the body is removed and a concave space is formed. The narrow space between the blade and the blade corresponds to the remaining portion 120 of the heat insulating plate, and the wide portion corresponds to each individual member 110 of the heat insulating plate.

Elastic members 12c 'and 12d', such as urethane foam, rubber pawls and silicone foam, are provided in the space between the blade and the blade so that when the cutter blade is pressed down on the heat insulating plate material, the mold 12 ' The elastic members 12c 'and 12d' are restored by the pressure lowered when the mold is lifted and the molds are lifted. As a result, the individual pieces of the cut insulating sheet material 110 and the remainder 120 remain on the support frame without rising along the mold 12 '.

6 shows a case in which the upper mold (frame) of the press cutter is of a flat plate type. Even in the case of the roller type, the surface portion on which the cutter blade is formed can be applied as it is.

The heat insulating plate material that has passed through the cut-off portion passes through the transitional portion in a state of being separated by the arrangement of the object 110 and the remainder 120. The transition portion comprises conveying roller pairs (21, 23) and conveying conveyor belt (26). The pair of conveying rollers 21 and 23 hold the objects 110 and the remainder 120 on the opposite side of the heat insulating material roll 11 wrapped around the press cutter and move the remainder 120 forward. The remaining portion 120 of the conveying roller pair is connected in its entirety when viewed in a plan view and is connected to a separate winding roller whose tip is not shown and is pulled down to be removed from the apparatus and wound by a winding roller to be recycled or discarded Out. Each of the entities 110 is in a state of being separated from the remainder 120 (see c in FIG. 8), wherein the size of the conveying roller pair 21 and 23 and the size of the redering unit and the conveying roller pair, The space between the conveying conveyor belts 26 is sufficiently smaller than the length of the object 110 (unit length in the traveling direction), and is transferred to the conveying conveyor belt 26 in the arrangement state. The roller 25 and the roller 27 serve to drive the conveying conveyor belt 26.

A laminating part is provided at the end of the conveying conveyor belt 26. The laminating unit includes a pair of conveying rollers 35 for receiving the insulator 110 placed on the conveying conveyor belt 26 forward and advancing the conveying rollers 35 forward. And the laminating sheet 200 is fed from the lower laminating sheet rolls 31, 33. Therefore, when the sheet is passed through the pair of conveying rollers 35, a plurality of objects 110 are arranged in a state of being laminated by the upper and lower laminating sheets 200 (refer to d in FIG. 8).

At this time, when the surface of the conveying roller pair is made of a flexible material and the thermal insulation material 110 and the upper and lower laminating sheets 200 are superimposed on each other and pressed against the surface of the stretchable conveying roller pair 35, only the upper and lower laminating sheets 200 overlap The upper and lower laminating sheets are brought into close contact with each other. If the adhesive layer or the adhesive layer is formed on the inner surface of the laminating sheet facing each other, the laminating sheet (hotmelt sheet) is fused and adhered to the laminating sheet, An additional portion may be formed. That is, the portion where the adhesion is made or the fusion-bonded portion is sealed in the space where the insulating material object is placed, so that even when the phase-change material of the insulating material object becomes a sol state outside the laminating sheet, it does not leak.

The second cutting section is provided again at the next position (front side) of the laminating section. The second cutter is provided with a press cutter similar to the preceding cutter, and the press cutter can have a similar configuration and operation to that of the previous cutter.

In this cutting part, only the laminating sheet is overlapped with the cutter blade to make the state of the laminating unit 210 as shown in FIG. 8E in which the laminating unit 220 is present in the laminating remainder 220. As a result, a plurality of laminating unit bodies 210 having a form of wrapping the insulator body with a wider area laminating sheet (film) can be arranged in the same arrangement as the insulator body 110 array in the previous stage.

The laminating part is provided with a covering part in a merged form at the next position. The portion performing the transition function of this cover portion may have a shape and function partially similar to the transition portion in front of the cutter portion described above. A conveying roller pair 55 and 56 made up of upper and lower rollers 55 and 56 and an auxiliary roller 57 rotating in contact with the lower roller 56 to remove the laminating residue 220. The pair of conveying rollers transport the laminating unit 210 and the laminating unit 220 in a state where they are separated from each other via the second cutter unit. The laminating remainder is removed from the arrangement of the laminating unit 210 by setting the leading edge already between the lower roller 56 and the auxiliary roller 57. Thus, the laminate unit array as shown in FIG. 8F remains.

A plurality of laminating unit pieces are arranged between the upper roller 55 and the lower roller 56 by arranging a plurality of laminating unit pieces between the upper roller 55 and the lower roller 56 at the same time, And the upper outer cloth 300 is supplied so as to overlap with the upper outer cloth 300. Therefore, after passing through the rollers 55 and 56 constituting the conveying roller pair, the upper laminating cloth 300 with the laminating unit pieces having the same arrangement (the arrangement as shown in FIG. 8) is attached to the upper laminating cloth 300 300 will advance forward.

Another pair of rollers 58 is provided in front of the conveying roller pair, and the lower outer sheath fabric 300 is fed from the roll 53 made of the lower outer sheath fabric. This lower cladding cloth 300 overlaps with the upper cladding cloth having the arrangement of the laminating unit 210, which has advanced in the roller pair 58, and becomes a lint so that it becomes a relative as shown in g of FIG.

As a result, the arrangement of the laminating unit 210 overlaps the upper and lower outer cloths 300. In this process, if there is an adhesive layer or an adhesive layer on the inner side of the outer cloth (the side facing the laminating unit), the upper and lower outer cloths are brought into close contact with each other by a pair of rollers, They are welded together to form an attached part without the insulating material unit. This can be done in a manner similar to adhesion or fusion of the upper and lower lamination sheets.

Thus, a thermal insulation material having the arrangement of the laminating unit 210 is formed between the upper and lower cloths 300. Such a heat insulation material can be wound on a reel to form a heat insulation material reel (60), and the heat insulation material can be manufactured by a subsequent process.

A sewing line 330, such as the one shown in Fig. 1, which forms a cell zone so that each laminating unit is not displaced from its position by sewing on the warming fabric, although not mentioned here, may be made before the reel is wound.

When the cloth or sheet to be supplied from the covering portion is applied to a human body, if sweat in the body is discharged or a certain portion of the ventilation function is provided, the resultant latent heat is transferred and absorbed The product can be processed and used to make a product such as a functional garment so as to maintain a temperature range different from extreme low temperature or high temperature.

Fig. 7 is a structural conceptual view showing an apparatus according to an embodiment different from the above embodiment, and shows a change in some configurations throughout the cutting section, the transition section and the laminating section.

In this embodiment, a plate-shaped mold is used as the upper press mold 12 of the press cutter in the cutting section, and a cutter 14 for cutting or cutting or an intermediate cutter frame is provided separately from the upper press mold 12. The bottom support frame uses the same flat base, although it is not particularly visible.

The cutter 14 can be cut at a position below the cutting cutter 14 while the heat insulating plate material 100 is placed on the lower support frame. . Therefore, the upper surface of the plate member is exposed on the cutting cutter 14 in a state of being cut and separated by the cutter blade. In the cutting step, the adhesive sheet 200a to be adhered to the upper surface of the insulating material object is already supplied between the cutting cutter 14 and the upper press mold 12, and the upper press mold 12 is generally plate- The surface of the sheet is convexly protruded downward corresponding to the insulating sheet material object. The upper press mold 12 and the cutting cutter 14 are vertically installed in a guide rod, and the peripheral portion thereof is passed through the guide rod so as to move up and down along the guide rod.

When the press cutter is operated in this state, the upper press mold 12 is pressed from the adhesive sheet 200a toward the cutting cutter 14 to press the cutting cutter 14 toward the heat insulating plate material 100 so that the cutter blade 14a The heat insulating plate material 100 is divided into an individual portion and a remaining portion. In addition, the portion 12a protruding downward of the upper press mold 12 causes the adhesive sheet to be adhered to the upper surface of the cut piece of the piece.

Therefore, when the upper plastic 12 is raised upward after the cutting, a plurality of insulating object parts are attached to the adhesive sheet in an arrayed state, and the upper part of the insulating material is raised to the original adhesive sheet height and is located above the cutting cutter 14. Only the remaining part of the insulating plate material remains on the lower support frame, and the tip end of the remaining part 120 is removed downward by the roller 23. The adhesive sheet can be used to easily separate the insulation array from the rest without the conveying belt when conveying to the next process, to keep the arrangement stably and to pass it to the next process. In the subsequent process step, the insulation sheet or the lamination sheet It is possible to continue to function in accordance with its characteristics.

The adhesive sheet advances forward by the pair of conveying rollers 35 and moves forward together with the arrangement of the insulating object attached to the adhesive sheet. This adhesive sheet may be regarded as a kind of upper lamination sheet, and a lower lamination sheet roll 33 is provided under the pair of conveying rollers to supply the lower lamination sheet 200b to the conveying roller pair.

As a result, in the pair of conveying rollers 35, the upper and lower portions are laminated and wrapped with lamination sheets to form an array of insulating material unit bodies or an integral laminated insulating object unit array.

Such a process can be applied in the same manner to the method of the present invention in which an array of laminated unit pieces is obtained in an integrated laminated insulating object arrangement and then a covering cloth or sheet is covered up and down again to form a warming material.

That is, in the apparatus configuration similar to that of FIG. 3, an integral laminated heat insulating object array is placed on the lower tray of the second cutter instead of the heat insulating plate (plate) placed on the first cutter, And an upper covering cloth or sheet having an adhesive layer on the lower surface thereof is placed between the cutting cutter and the upper press frame instead of the adhesive sheet 200a placed on the first cut portion and cut to form the lamination unit arrangement The remaining portion is physically separated, and the lower covering cloth or sheet is fed from the next pair of rollers between the second cutting portion and the covering portion, and the covering portion next to the pair of rollers is provided on both the upper and lower sides of the laminating unit array Take a cloth or sheet covered. Then, the remaining part is pulled downward between the pair of rollers and the second cutter so as to be spatially separated from the arrangement of the laminating unit pieces.

The subsequent process can be carried out in a similar manner to the embodiment of FIG. 3 which has been described above, such as making a unit cell by sticking, bonding, welding, etc. so that each of the laminating units does not change its position on the insulating material, It will be omitted.

Of course, in this process, if the sheet used in place of the pressure sensitive adhesive sheet is not suitable for the covering cloth or sheet, it is removed in the previous stage of the conveying roller pair, and a cloth or sheet is fed up and down as in the embodiment of Fig. The array of the unit body may be wrapped.

Various materials and phase change materials known in the art can be used for the insulation material, and it is convenient to select a material which can be made or used as a gel having a required thickness by impregnating the phase change material on the base material.

Lamination films or lamination sheets can use a variety of synthetic resin films that can prevent phase transfer materials from leaking out or impregnating.

The shape of the mold for separating the insulation material into a plurality of pieces can be formed by three-dimensional (3D) processing using CNC, and can be used in combination with the pressurizing device. In a roll-shaped mold or a flat mold, when the cutter blade portion for cutting is formed, the mold is filled with a stretchable member in a concave space on the bottom surface of the main body. When the mold is lowered, And push the remainder out of the mold so that no object or residue comes in the mold.

Although not shown and described in detail in the above embodiments, a movable structure such as a roller or a press cutter and a continuous or intermittent movable pattern can be variously formed by a well-known structure, and if necessary, It is also possible that a machine element is further provided.

A configuration in which the surface of the roller is made of a stretchable high-elastic material and the sheet or fabric passing between the sheets is pressed or heated on both sides is well known in the art, so that a detailed description is omitted here.

In the present invention, by using a laminate of a heat insulating material as a heat insulating material unit, the sheath material is used as permeability or permeability to a phase change material, and even when the heat insulating material is phase-transformed into a sol-gel state in the future, The problem of being detached from the position and leaking from the fabric and being damaged can be solved. Repeated mechanical force or manipulation is applied. For example, in order to use a thermal insulating material as an industrial material such as a packaging material, it is necessary to adjust and select the laminating film material and fusion bonding or adhesion strength to a suitable level.

On the other hand, when fabricating a thermal insulation material of the present invention by adhering and fusing the outer sheet or cloth to the material tailored to the function when the outer sheet or cloth is bonded to both sides of the lamination unit arrangement, the lamination sheet fused portion of non-breathable and non- So that the characteristics of the functional material fabric can be well realized.

The area where the insulation material is separated by the lamination fusion part and the functional fabric separation and the area for separating the insulation material unit can be provided so as to be smooth and easy to operate because there is no stiff material, and the cell can be provided by seam, It is possible to secure the durability even in washing or friction, or in a portion subjected to load like shoes.

The functional fabrics for the jacket include industrial fabrics such as general polyester materials, life-like fabrics such as cotton, high-temperature resistant capillaries, aramid fabrics, polyimide high-temperature films and submerged fabrics, all films capable of coating adhesive, A fiber material may be used.
