Description

  The present invention relates to a waist plate and a decorative molding that are used as interior materials such as a wall surface and a ceiling, are particularly excellent in workability and workability, and can be easily shaped and adjusted in size.

  A cross is mainly used as an interior decoration of a building. On the other hand, the cloth alone is monotonous and the cloth is generally easily scratched and soiled, improving the scratch resistance and stain resistance on the interior wall surface, especially the lower part of the indoor wall surface (especially at the waist). For the purpose, a waist wall formed by stretching a decorative waist plate is provided. The waist wall is constructed by placing waist plates one by one at the lower position of the wall base and fixing them with nails or an adhesive. For this reason, the construction requires skilled skills and labor, and there is a problem that construction cannot be performed easily unless an expert.

  Therefore, a natural wood plank is used as a front plate, and a protruding engagement piece is fitted to one side edge of the front plate, and a locking groove into which a protruding engagement piece of a front plate adjacent to the other side edge is fitted is formed on both upper and lower edges. A protruding engagement piece that fits into the locking groove of the skirting board, and a groove for preventing warpage along the longitudinal direction of the front plate at the center of the back surface, and the front plate on the both sides are bonded to the substrate An adhesive surface to be fixed and a non-adhesive surface to which the front plate is not fixed to the substrate are formed, and a plurality of front plates are brought together with each other between the baseboards that are vertically arranged to be bonded and fixed to the substrate together with the baseboards. A waist plate block characterized by this is proposed (see, for example, Patent Document 1).

  This waist plate block forms a non-adhered part on a part of the front plate, and is also non-adhered to the baseboard, so that even if the front plate absorbs moisture and dries, the expansion / contraction allowance of the plate is It is said that it can be absorbed at the unbonded portion and warpage is prevented. Moreover, since it can be formed as a unit of a predetermined size, it can be easily installed even by an amateur and can be easily handled even in a narrow room.

  Further, a building material panel or the like in which a veneer obtained by slicing a thin slice of natural wood is bonded to the surface of a non-woody core material (base material) is disclosed (for example, see Patent Document 2). In this building material panel, the appearance can be made the same as that of natural wood by adhering a veneer made of natural wood to the surface of the core material. In addition, by using a plastic foam or the like as the core material, it is said that excellent physical properties that cannot be realized with natural wood, such as heat insulation characteristics and sound insulation characteristics, can be improved. Thus, as an example using a non-woody core material, for example, an inorganic foam and an organic binder are provided between the front and back layers containing mineral fiber, inorganic powder and organic binder as essential components. A decorative board is disclosed in which a core layer as an essential component is laminated and integrated, and a veneer is attached to the surface (see, for example, Patent Document 3). Also, a laminated panel comprising a hard face plate disposed on both surfaces and a plurality of foamable resin layers sandwiched between the two faceplates, wherein the faceplate and the plurality of foamable resin layers are joined to each other. A manufacturing method and the like are disclosed (for example, see Patent Document 4).

  Next, an embodiment for carrying out the present invention will be described with reference to the drawings. 1-8, the same code | symbol shows the same member or the same component. As shown in FIG. 1, the waist plate of the present invention has a base material 11, and a wood thin plate 13 a is laminated on the surface of the base material 11 via an adhesive layer 12, and a wood thin plate via an adhesive layer on the back surface. The laminated body 15 in which 13b or the paper material 14 is laminated | stacked is comprised as a base | substrate.

<Base material>
The substrate 11 is mainly composed of a plate-like foam made of a thermoplastic resin. The plate-like foam made of a thermoplastic resin can be used without particular limitation as long as a base material mainly composed of a thermoplastic resin is foamed by a chemical or physical method. Specifically, polypropylene, polyethylene, ethylene-vinyl acetate copolymer, or polyolefin resin, polyester resin, polyvinyl chloride, ABS, polystyrene, polyacrylonitrile, polyurethane formed by appropriately mixing two or more of these, A melamine resin, a phenol resin, etc. are mentioned. Among these, polystyrene is particularly preferable from the viewpoints of processability, lightness, surface smoothness, and the like. Moreover, it is preferable that it is 8-80 times practically, and it is especially preferable that the expansion ratio of resin is 10-20 times. Moreover, it is preferable that thickness is 3-15 mm from a viewpoint of workability or cost. Since the plate-like foam made of such a thermoplastic resin is lightweight, workability during construction can be improved by using the plate-like foam as the base material 11. Moreover, since it is excellent in heat retention, the same characteristics can be imparted to the waist plate itself.

  Further, as shown in FIG. 3, the base material 11 constituting the laminated body 15 may be composed only of the above-described thermoplastic resin plate-like foam 11a. However, as shown in FIG. A material in which a sheet-like surface material 11b is bonded to both surfaces of a foam 11a can also be used as the substrate 11. By laminating the sheet-like surface material 11b on both surfaces of the plate-like foam 11a, it becomes difficult to warp compared to the case where these are not laminated. The sheet-like surface material 11b is inexpensive, for example, and is preferably a paper material in terms of productivity and adhesiveness. Examples of the paper material include post-printed paper, art paper, coated paper, chemical fiber paper, synthetic paper, resin-impregnated paper, and synthetic resin processed paper in which polyethylene or the like is laminated on one side or both sides.

  As the adhesive used for bonding the plate-like foam 11a made of a thermoplastic resin and the sheet-like surface material 11b constituting the base material 11, a general adhesive can be used. For example, when classified according to the main component in the adhesive, starch and modified products thereof, gelatin and modified products thereof, natural polymeric adhesives such as casein, pullulan and albumin, polyvinyl alcohol and modified products thereof, polyacrylamide, polyvinyl pyrrolidone, Thermosetting properties of water-soluble synthetic polymer adhesives such as polyethyleneimine, polyethylene glycol, polypropylene glycol, maleic anhydride polymers or copolymers thereof, urea resins, melamine resins, phenol resins, epoxy resins, urethane resins, etc. Resin adhesive, acrylic resin, acrylic-styrene resin, vinyl acetate resin, ethylene-vinyl acetate resin, vinyl chloride resin, polyamide, polyolefin, polyester and other thermoplastic resin adhesives, chloroprene rubber, nitrile rubber, SBR, etc. Elastomer Adhesive and the like. The method for applying these adhesives to the front and back surfaces of the plate-like foam 11a made of thermoplastic resin is not particularly limited, and can be performed by a method such as a spreader, a spray, or a curtain coater.

<Wood thin plate>
As the wood thin plate 13a laminated on the surface of the base material 11, a natural wood thin plate (single plate or veneer) or plywood obtained by thinly slicing natural wood into a plate shape can be used. Examples of natural tree species in the case of using a natural wood sheet include zelkova, oak, kiri, hinoki, cedar, mahogany, walnut, oak, teak, hippopotamus, rosewood, and kokutan. The thickness of the natural wood sheet is preferably 0.2 to 3 mm. If the thickness of the natural wood sheet is too thin, it may be easily damaged, while if it is too thick, it will be difficult to easily adjust the size using a cutter, etc., and workability and workability will be reduced. There is.

  When using a plywood for the thin wood board 13a, it is preferable that the thickness is 1-3 mm. Plywood of less than 1 mm is generally difficult to manufacture or obtain. On the other hand, if it exceeds 3 mm, it is difficult to adjust the size easily using a cutter, etc. May decrease. Specific examples of plywood include ordinary plywood that is widely used for general purposes, natural wood decorative plywood with a thin veneer of natural wood on the surface of ordinary plywood, or aesthetics and durability on the surface of ordinary plywood. For example, a specially processed decorative plywood or the like having a wood grain pattern or the like applied by printing or the like may be used.

  The surface of the wooden thin plate 13a may be painted or unpainted, but if it is unpainted, even an amateur can use a commercially available ink, etc., to easily perform painting construction according to his / her preference, and Can be done freely. Moreover, as shown in FIG. 5, for example, grooves 18 parallel to the fiber direction of the wood thin plate 13a may be formed on the surface of the wood thin plate 13a at equal intervals. This groove 18 is formed by adhering together a plurality of thin wood plates 13a formed by forming an adhesive layer 12 to be described later on an underside and cutting them to an appropriate width one by one while providing a slight gap. It is formed. Further, for example, a single large thin wood plate 13 may be laminated on the base material 11 to form a laminate, and then formed by a method of cutting using an NC router or the like. Thereby, decorativeness can be provided, without impairing the natural texture, while improving mass productivity.

The wood thin plate 13b laminated on the back surface of the base material 11 is similar to the wood thin plate 13a laminated on the surface of the base material 11 described above except that, for example, surface decoration is not required. Alternatively, plywood can be used, and the same thickness can be used, that is, a thin wood plate of 0.2 to 3 mm in the case of a natural wood thin plate, and 1 to 3 mm in the case of plywood. Further, instead of laminating the wood thin plate 13b described above, a paper material 14 may be laminated on the back surface of the base material 11. As the paper material 14 laminated on the back surface of the base material 11, for example, a paper material such as a reprint used for the above-described sheet-like surface material 11 b can be used. It is preferable that the paper material 14 laminated | stacked on the back surface of the base material 11 is the range of 50-300 g / m < ² > basic weight from a viewpoint of workability and a curvature prevention. In addition, the surface of the base material 11 or the laminated body 15 means the surface located in the front (decoration surface) side of the waist board 10 visually recognized from indoor space, when the waist board 10 is constructed, for example in the wall surface etc. of a room | chamber interior. On the other hand, the back surface of the base material 11 refers to a surface located on the back (contact surface) side of the waist plate 10 that is not visually recognized from the indoor space by adhesion to a wall surface or the like. By laminating the thin wood plate 13b on the back surface, it is possible to suppress warping caused by environmental changes such as temperature and humidity.

<Adhesive layer>
The adhesive layer 12 for adhering and laminating the wood thin plates 13a and 13b or the paper material 14 to the front and back surfaces of the base material 11 can be formed using a general adhesive or pressure-sensitive adhesive. Specific examples of the adhesive used for forming the adhesive layer 12 include a latex thermosetting adhesive and a vinyl acetate adhesive. The above-mentioned vinyl acetate adhesives include not only vinyl acetate adhesives but also adhesives mainly composed of polyvinyl acetate, for example, two-pack type water-based adhesives incorporating a curing mechanism (reactive special vinyl acetate resin). Emulsion) and the like. Moreover, as said adhesive, well-known adhesives, such as an acrylic resin type and a rubber type, can be used. The adhesive layer 12 may be formed on the adhesive surface on the base material 11 side, or may be formed on the wooden thin plates 13a and 13b or the adhesive surface on the paper material 14 side.

<Adhesive layer>
In addition, as shown in FIG. 2, the waist plate 10 of the present invention may further have a pressure-sensitive adhesive layer 16 formed on the back surface of the above-described laminated body 15, and a release paper 17 may be further laminated on the pressure-sensitive adhesive layer 16. . In this way, by forming the pressure-sensitive adhesive layer 16 on the back surface of the laminate 15 in advance, it is not necessary to prepare a separate adhesive or the like when constructing, and the release paper is peeled off and applied to the wall surface or the like. Construction can be done with a simple task of attaching. The pressure-sensitive adhesive layer 16 may be formed on the entire back surface of the laminate 15 or may be partially formed. When the adhesive layer 16 is not formed, a double-sided tape or the like can be appropriately selected and pasted according to the state of the adherend surface such as a wall material or the adhesive strength required by the installer.

  For the formation of the pressure-sensitive adhesive layer 16, a rubber-based or acrylic resin-based pressure-sensitive adhesive can be used. The main raw material for rubber adhesives is natural rubber or styrene-butadiene rubber, and rosin resins and plasticizers are added to rubber adhesives made mainly of natural rubber. Use to coat. The rubber-based pressure-sensitive adhesive mainly composed of styrene / butadiene rubber is a hot-melt type pressure-sensitive adhesive, which is melted and applied. The acrylic resin adhesive is produced by polymerizing acrylic monomers such as 2-ethylhexyl acrylate, butyl acrylate, ethyl acrylate, acrylic acid, and β-hydroxyethyl acrylate. Depending on the polymerization method, an organic solvent such as ethyl acetate or toluene, or an emulsion type polymerized while emulsifying in water using a surfactant can be used.

  In order to improve physical properties of the pressure-sensitive adhesive layer 16 such as heat resistance and solvent resistance, the pressure-sensitive adhesive raw material may be subjected to a crosslinking reaction using a crosslinking agent such as isocyanate, melamine, or metal chelate. Also, pigments such as silica, kaolin, clay, calcium carbonate, aluminum hydroxide, melamine resin particles and starch particles can be added, water-soluble polymers, petroleum resins, various paraffin waxes, fatty acids or derivatives thereof, higher alcohols , Metal soaps, silicones, and further antistatic agents, thickeners, dispersants, preservatives, antioxidants, antifoaming agents and the like may be added. These pressure-sensitive adhesives may be appropriately selected according to the environment, usage, and the like in which the waist plate 10 is constructed.

  As a specific method for forming the pressure-sensitive adhesive layer 16, for example, a pressure-sensitive adhesive is applied to a surface of a release paper 17 to be described later, and a surface to which the pressure-sensitive adhesive is applied and a back surface of the laminate 15 are attached. In addition, there is a method of pressure bonding with a press roll or the like. Moreover, the method of apply | coating an adhesive previously to the back surface of the said laminated body 15, and bonding a release paper may be used.

  As a method or apparatus used when applying the adhesive, in addition to an air knife coater, blade coater, bar coater, roll coater, slot nozzle, slot die, rotary screen printer, gravure coater, offset gravure coater, hot melt wheel, Examples include spiral spray. What is necessary is just to select suitably considering the kind of adhesive to be used, an application amount, or the necessity to give a pattern to the adhesive to apply.

<Release paper>
The release paper 17 provided on the adhesive layer 16 is formed by applying a release agent to one side of a substrate such as paper. Examples of the substrate constituting the release paper 17 include high-quality paper, craft paper, glassine paper, and plastic film. Examples of the release agent include silicone resin. In the case of using a paper-based substrate such as fine paper, the release property can be improved by applying a release agent after smoothing the surface by laminating a thermoplastic resin on the substrate. The direct application of the release agent on the paper-based substrate is called the direct type, the laminate on which the release resin is applied after laminating the thermoplastic resin on the paper substrate is called the polylamination type, and the one applied directly on the plastic film is called the film type In this case, a release paper suitable for the application may be selected from each of them. Further, when it is necessary to ensure curling aptitude, it is preferable to laminate a thermoplastic resin or coat a synthetic resin as a back surface treatment on the opposite surface of the base material coated with a silicone resin. For special applications, a non-silicone release agent may be used.

<Decoration molding>
Further, the waist plate 10 of the present invention may be provided with a strip-shaped decorative molding 20 as shown in FIGS. 6 and 7 on the upper edge and / or the lower edge, for example. As shown in FIG. 8, by providing the decorative molding 20, the decorative properties of the upper edge and / or the lower edge of the laminated body 15 that are exposed can be easily enhanced.
