Description

TECHNICAL FIELD [0001] The present invention relates to a composite waterproof sheet and a composite waterproofing method using the waterproof sheet.

The present invention relates to a composite waterproof sheet and a composite waterproofing method using the composite waterproof sheet. More particularly, the present invention relates to a composite waterproof sheet having a waterproof layer and a waterproof layer The problem of water leakage due to detachment or peeling of the joining part which is a problem of sheet waterproofing is solved and the problem of the waterproofing layer being destroyed by the gel waterproofing layer flexibly responding to the behavior of the ground surface is solved A composite waterproof sheet which improves the reliability of the waterproof construction by allowing the waterproof performance to be maintained for a long time by allowing the gel waterproof layer to penetrate into cracks or cracks when cracks and cracks are generated on the base surface, .

Generally, the waterproofing method applied to the waterproofing of underground concrete structures such as roofs and underground foundation floors and underground outer walls of building structures, waterproofing of upper slabs of underground parking lots and civil engineering structures such as subways, underground roads, Typically, it can be classified into sheet waterproofing, film waterproofing and composite waterproofing.

Waterproofing of sheet is waterproofing of asphalt sheet due to insufficient adhesion of asphalt sheet to concrete base surface and waterproofing of asphalt compound when it is heated and fused by using torch at joint part of waterproof sheet connection. There is a problem that leakage of water from the joint portion frequently occurs because the watertightness at the seat connection joint portion is weakened.

That is, it is easy to realize the required physical properties through various laminated structures in the production of the sheet, easy to secure uniform thickness and quality, and easy to install. On the other hand, sheet waterproofing is difficult to construct complex parts, And it is difficult to perform the sheet end portion and the corner treatment, and the watertightness at the joint portions (joints) between the sheets is weak, so that complete watertightness is hardly achieved.

Waterproofing of the coating film varies depending on the material. Typically, it is a method of applying urethane coating film waterproofing and rubber asphalt coating film waterproofing easily by using rollers or brushes, and it is excellent in workability and waterproofing layer stretchability to cope with micro cracking of concrete structure However, it is difficult to form an even thickness of the waterproofing layer because the waterproofing layer must be applied several times, and the waterproof layer is frequently formed due to partial bubbles or acorns of the waterproof layer. have.

In addition, since the waterproofing of the coating film is a close adhesion method to the bottom surface of a concrete surface or the like, it is vulnerable to crack cracking, so that it is difficult to fundamentally solve the crack of the lower limb, and the urethane coating film formed at the time of cracking is damaged, , The smoothness of the substrate and the drying condition are greatly influenced. Since the liquid is applied in a liquid state and flowability is good, the thickness of the coating film may be uneven due to the curvature of the bottom surface, There is a drawback that it is not easy to upgrade.

On the other hand, the combined waterproofing, which is a composite structure of sheet waterproofing and film waterproofing to compensate for the disadvantages of sheet waterproofing and film waterproofing described above, is a combination of a polymeric or asphalt waterproofing sheet and a coating film waterproofing material applied by a hot- This is the most common.

However, in the composite waterproofing described above, a solvent type or a water-soluble asphalt coating waterproofing material is generally used as a coating waterproofing material. In order to secure the thickness of the coating film, a coating operation must be performed several times. Since the construction cost is excessive and the waterproof sheet can be attached after the coating film waterproofing material is cured, the increase of the construction period and the construction cost becomes more remarkable, and the heat treatment method When the method is applied, there is a risk of fire and generation of harmful substances.

The nonwoven fabric of the nonwoven fabric layer 204 is formed by a gel waterproof layer 106 so as to cover the gel waterproof layer 106 applied to the base surface 102 in the complex waterproofing method using the composite waterproof sheet 200, And the waterproofing material of the gel waterproofing layer 106 is impregnated into the nonwoven fabric layer 204 so that the nonwoven fabric layer 204 and the PVC layer 202 and the gel waterproofing layer 106 are integrated with each other.

1, a mesh network 206 made of any one of polyester or glass fiber is attached to the upper surface of the PVC layer 202 while being pressed.

The mesh or network of the polyester mesh network 206 or the glass fiber mesh network 206 has an interval of 3 mm to 5 mm and the mesh network 206 is a multi- When the urethane coating waterproofing material is applied to the upper part of the composite waterproof sheet 200 according to the present invention installed on the gel waterproofing layer 106 in the composite waterproofing method using the waterproof sheet 200, The layer 206 is impregnated into the warp and weft of the mesh net 206 attached to the top of the PVC layer 202 while being penetrated into the mesh or net formed by warp and weft and attached to the PVC layer 202 , The urethane coating film waterproofing material and the PVC layer 202 are integrated with each other.

At least one of the warp yarns and the weft yarns constituting the mesh net 206 may be formed by mixing at least one strand of a yarn with a metal material to improve the tensile strength of the mesh net 206. In addition to impregnating the urethane film- When the urethane coating waterproofing material is cured (top coat layer 110), when the coating film is shrunk, the mesh net 206 is firmly adhered to the PVC layer 202 so that the PVC layer 202 and the top coat layer It is preferable to prevent the floating phenomenon from occurring.

In the present invention, as shown in FIG. 1, a long or short fiber nonwoven fabric having a weight of 100 g / m 2 to 200 g / m 2 is attached to the upper portion of the polyester mesh net 206 or the glass fiber mesh net 206 by heat It is preferable to further form the reinforcing layer 208.

The nonwoven fabric of the reinforcing layer 208 may be formed to have a lower density than the nonwoven fabric of the nonwoven fabric layer 204 formed on the lower surface of the PVC layer 202 to facilitate impregnation or penetration of the liquid urethane coating waterproofing material, 206 to protect the PVC layer 202 from external impact while maintaining the integrated attachment function of the urethane coating waterproofing material and the PVC layer 202.

5, when the nonwoven fabric layer 204 is attached to the lower portion of the PVC layer 202, the composite waterproof sheet 200 according to the present invention may be bonded to one side or the other side of the PVC layer 202 The wings 210 may be continuously formed at one end or the other end of the lower surface of the composite waterproof sheet 200 along the longitudinal direction of the composite waterproof sheet 200 Let's do it.

Accordingly, when the composite waterproof sheet 200 is joined to form a joint, the lower surface of the composite waterproof sheet 200 is overlapped by the wing 210, It is preferable to increase the binding force or the binding force.

Meanwhile, the composite waterproof sheet 200 according to the present invention having the above-described structure is applied to a waterproofing method using a composite waterproof sheet described below, and will be described with reference to FIGS. 2 and 5.

First, a primer layer 104 is formed on a base surface 102 after the base surface 102 has been formed. Then, a primer layer 104 is formed on the primer layer 104, Thereby forming a gel-water-proof layer 106.

When the waterproofing material 106 is applied to the ground surface 102 while maintaining the state of the gel material (gel) (semi-solid shape), the gel waterproofing layer 106 directly penetrates into the fine gaps of the ground surface 102, It has a merit of increasing the waterproof performance because it penetrates into cracks.

The gel-like coating material waterproofing material according to the present invention comprises 25 to 35% by weight of a rubber asphalt compound, 40 to 50% by weight of a mixture of a styrene copolymer and 1,3-butadiene, 10 to 20 wt% of a regenerated vegetable oil, 15 to 25 wt% of a plasticizer, 10 to 15 wt% of a liquid acrylic latex mixed with 60 wt% of a vegetable oil, at least one selected from waste cooking oil, olive oil, sunflower seed oil and rosin, At least one selected from the group consisting of zinc oxide and magnesium oxide, at least one selected from among zinc oxide and magnesium oxide, at least one selected from the group consisting of grafted 7 to 12 wt%, rubber modifier 4 to 8 wt%, crosslinking agent 3 to 6 wt%, toluene, xylene, 2 to 5% by weight of an inhibitor, and 1 to 5% by weight of a stabilizer.

Among the above-mentioned gel-like coat waterproofing materials, the rubberized asphalt compound is composed of any one of straight run asphalt, blow asphalt, straight run asphalt and blown asphalt, The rubber is made of one selected from the group consisting of SBS (Styrene Butadiene Styrene) rubber, SB (Styrene Butadiene) rubber, SEBS (Styrene Ethylene Butadiene Styrene) rubber, SIS (Styrene Isoprene Styrene) rubber, and Butylene rubber. %, The adhesion performance of pushing out and adhering the water on the surface when the surface 102 is humidified is lowered, and the manufacturing cost is increased to 35% by weight, so that it is suitably from 25% by weight to 35% by weight.

The above-mentioned gel-like coating film waterproofing material includes a liquid acrylic latex prepared by mixing 40 to 50% by weight of a mixture of a styrene copolymer and 1,3-butadiene with 50 to 60% by weight of water 10 to 15% by weight is added.

The liquid acrylic latex can improve long-term durability while providing excellent adhesion force through good packing effect of polymer particles, better penetration into the voids of concrete structure to provide more improved adhesion, and addition of less than 10% The viscosity is lowered and the permeability is lowered. When the amount is more than 15% by weight, the flowability is excessively improved, resulting in a dropping phenomenon on the adhered surface, resulting in poor workability.

The regenerated vegetable oil, which is selected from at least one of waste cooking oil, olive oil, sunflower seed oil and rosin, is added to the gel coat film waterproofing material. The regenerated vegetable oil can serve as a plasticizer or softener, , It is possible to obtain an inexpensive manufacturing cost by replacing expensive process oil, and by recycling incineration or abandoned vegetable oil, it is possible to obtain natural environment protection and import substitution effect.

When the regenerated vegetable oil is added in an amount of less than 10% by weight, the effect of reducing the raw material is insignificant. When the added amount exceeds 20% by weight, the function and effect of the process oil deteriorate.

A plasticizer is added to the gel coat film waterproofing material. The plasticizer is added so that the rubberized asphalt compound maintains the gel state viscosity at room temperature to have permanent elasticity and flexibility. The process oil may be at least one selected from the group consisting of Paraffinc Oil, Naphthenic Oil and Aromatic Oil, or may be formed of glycol oil or mineral oil Sprit Oil), and also helps to increase the water resistance of the rubber asphalt compound. When the amount of the rubber-based asphalt coating material is less than 15% by weight based on 100% by weight of the gel-like coating waterproofing material, %, There is a problem that the gel state can not be maintained and the gel state is reduced

The above-mentioned gel-like coating film waterproofing material is added with a tackifier to improve the adhesion performance of the gel-like coating material waterproofing material, such as bonding strength, adhesive strength, heat resistance, etc. The tackifier is obtained by adding a natural resin, If it is added in an amount of less than 7% by weight based on 100% by weight of the total amount of the gel-like coating film waterproofing material, heat resistance deteriorates due to loss of adhesive force, loss of adhesion between other materials, , It leads to an increase in the production cost due to the high temperature, and it is easily oxidized by the ultraviolet ray, heat and other environment, and the weather resistance is degraded.

The rubber modifier to be added to the gel coat film waterproofing material is to selectively increase the viscosity / durability of the rubber asphalt compound, increase the low temperature bending property, and mix it with PIB rubber (Poly Isobutylene Rubber) or polybutene When the addition amount of the rubber modifier is less than 4% by weight based on 100% by weight of the gel coat film waterproofing material, adhesion with the concrete base surface 102 is deteriorated.

In order to stably maintain the physical properties of the crosslinked rubber asphalt compound added to the gel coat film waterproofing material, when the addition ratio is 3% by weight or less, there is no crosslinking ability, and when it is 6% by weight or more, the rubber asphalt compound is hardened hardly, There is a problem in that the risk is followed.

The solvent added to the gel-like coating film water-repellent material is preferably highly volatile such as toluene and xylene, and at least one of them is selected. It is preferable to add 3 to 7% by weight to improve workability, Is added in an amount of less than 3% by weight, the viscosity is increased and melting and mixing are difficult, and when added in an amount exceeding 7% by weight, the cost is increased and the mixing time is delayed due to volatilization delay.

The antioxidant added to the gel coat film waterproofing material is one selected from at least one selected from zinc oxide and magnesium oxide for enhancing the thickening effect, flow-preventing effect, storage stability and durability of the rubber asphalt compound, When the ratio is 2% by weight or less, the oxidizing agent is not oxidized easily, and is easily oxidized by oxygen in the ultraviolet rays, heat, and air, and the weather resistance is remarkably decreased to prevent the oxidation. When the amount is 5% by weight or more, the physical properties of the rubber asphalt compound are changed The problem of interfering with the crosslinking reaction and the weatherability are improved to some extent, but the effect is not significant.

The stabilizer added to the gel coat film waterproofing material is selected from vinyl chloride (Vinyl chloride), lead stearate, Cadmium stearate, Barium stearate, 1 wt% to 5 wt% However, the addition of less than 1% by weight is insignificant, and when added in an amount of more than 5% by weight, the addition amount of the rubbery asphalt compound The changer has a problem.

The gel-based coating material waterproofing material according to the present invention, which is formed by mixing the above-described components, has excellent elasticity and flexibility while maintaining a gel-like viscous state, copes with the occurrence of microcracks in the concrete structure, And acts as an adhesive between the concrete surface 102 and the composite waterproof sheet 200 according to the present invention.

After the gel waterproof layer 106 is formed by applying the gel coat film waterproofing material to the primer layer 104 of the base surface 102 as described above, the composite waterproof sheet 200 according to the present invention is applied to the gel waterproof layer 106 The step of forming the sheet waterproofing layer 108 by attaching to the upper part allows the gel waterproofing layer 106 to be protected by the composite waterproofing sheet 200. [

In the step of forming the sheet waterproofing layer 108, as shown in FIG. 2, overlapping construction in which adjacent composite waterproof sheets 200 are brought into contact with each other, overlapping with a certain width, The joints are formed by selecting any one of the end portions of adjacent composite waterproof sheets 200 spaced apart from each other by a predetermined distance.

As described above, in the case of adopting the exposure waterproof sheet 200 according to claim 4 according to the present invention, one composite waterproof sheet 200 and another composite waterproof sheet 200 The wings 210 formed on the lower surface of one composite waterproof sheet 200 are overlapped with the lower surface nonwoven fabric layer 204 of the other waterproof sheet 200 It is preferable that the overlapping construction can be performed at the same time so that the lateral binding force between the composite waterproof sheets 200 can be strengthened.

The step of forming the top coat layer 110 by applying the urethane coating waterproofing material to the upper portion of the waterproof layer 108 is performed to complete the composite waterproofing method using the composite waterproof sheet 200.

At this time, in the joint formed at the joint, the urethane coating waterproofing material penetrates the upper part of the urea coating waterproofing material to penetrate the upper part of the joint, So that a more limited waterproofness can be secured.

Here, in the step of forming the joint, it is possible to select a belt construction in which the side ends of adjacent adjacent composite waterproof sheets 200 are spaced apart from each other by a certain distance. In this case, the separation distance is preferably about 2 mm to 4 mm, Is easily filled into the space separated by the batt structure as shown in Fig. 3 so that the urethane coating waterproofing material is bonded to the lower part of the gel waterproof layer 106, whereby the gel waterproof layer 106, the sheet waterproof layer 106, It is preferable to maximize the integrity of the top coat layer 108 and the waterproof performance of the top coat layer 110.

As described above, the composite waterproof sheet 200 is applied to the base surface 102 after the gel coating film waterproofing material is applied to the base surface 102, so that the structure of the waterproof sheet can be formed in the field, The waterproofing layer 106 formed on the concrete ground surface 102 performs a primary waterproofing and damping function and is in a cured gel state The elasticity and elasticity of the waterproof layer 106 can be maintained and the strong adhesion with the ground surface 102 can be prevented to prevent lifting or peeling. The sheet waterproof layer 108 applied on the gel waterproof layer 106 has a secondary waterproof and moisture- And the adhesive force of the adhesive layer 110 is secured with the gel-waterproof layer 106, thereby forming a perfect one sheet. In the case of the sheet-waterproofing, the top coat layer 1 10, and a tertiary waterproofing / dewatering function is performed by the topcoat layer 110, so that a triple complex waterproofing can be realized.
