[0001]

[Technical field to which the device belongs]

 The present invention relates to a building material sheet and building material used as a surface material for furniture, a surface material for building materials, and the like.

[0002]

[Prior art]

 A conventional building material sheet is obtained by a method called a doubling method in which a design is provided on the surface of a colored vinyl chloride sheet by a printing method, and a transparent sheet is thermocompression-bonded on the design layer. There was something. In addition, in order to enhance the texture of the building material sheet, there were cases where a wood grain conduit or embossing that adjusts the surface gloss was processed into a transparent sheet during the doubling process. In some cases, a wiping method was used in which embossed recesses were filled with a coloring material to express the wood grain conduit portion.

[0003]

[Problems to be solved by the device]

 However, the building material sheet obtained by the doubling method did not have sufficient hiding power for the toned colored vinyl chloride sheet. For example, when the base material is plywood, it could be affected by the color variation of the plywood. That is, in the doubling method, a polyvinyl chloride resin is usually mixed with various additives and a coloring agent to form a sheet having a thickness of 70 to 100 μm, which is used as a colored base sheet. The following colorants are used as colorants, but it is necessary to use a large amount of inorganic pigments in order to obtain sufficient hiding power. In particular, when it is desired to obtain a yellowish color, it is necessary to use a heavy metal-based pigment among the inorganic pigments. However, inorganic pigments are generally more expensive than organic pigments.

Hue Inorganic pigment Organic pigment −−−−−−−−−−−−−−−−−−−−−−− Yellow lead Disazo yellow Orange Chromium vermilion dinitroaniline orange Red azo lake Brown Benji benzimidazo Ron Black carbon black White titanium oxide

In the market, it is the actual situation that the heavy metal-based pigment is provided in the minimum necessary amount to the extent that there is no problem in normal use. Therefore, if there is a partial black knot on the plywood that is the base material, the building material sheet made by the doubling method will not be able to cover up that part, and the grain of the building material sheet will appear to change in color. It was

[0006] Therefore, the object of the present invention is to solve the above-mentioned drawbacks and provide a building material sheet and a building material that always have stable color development without being affected by the color of the base material.

[Embodiment of device]

 An embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of a building material sheet of the present invention. FIG. 2 is a sectional view showing another embodiment of the building material sheet of the present invention. In the figure, 1 is a base sheet, 2 is a wood grain layer, 3 is a wood base layer, and 4 is a protective layer.

The building material sheet is formed by sequentially forming a grain pattern layer 2 and a grain base layer 3 on the back surface of a transparent base sheet 1 (see FIG. 1).

As the base sheet 1, a transparent one is used. As the material, vinyl chloride, olefin film, polyester, polyimide, polyamide, polycarbonate, polyvinyl chloride, polypropylene, polystyrene, acryl, acrylic rubber, etc., which are usually used as building material sheets, may be used. The thickness of the base sheet 1 is preferably 16 to 500 μm. Particularly, if it is 100 to 200 μm, it is suitable for post-processing such as bonding to a base material.

The grain pattern layer 2 is formed on the base sheet 1. The grain pattern layer 2 is provided to express a pattern such as grain. It also has the ground color function that the vinyl chloride sheet colored by the conventional doubling method played. Therefore, the layer is not limited to one color, and may be a multicolor layer. As the wood grain pattern layer 2, a coloring ink composed of an ordinary pigment or dye and a binder or an additive is used. Specifically, coloring materials such as pigments, dyes and pearl pigments, and acrylic resins, vinyl acetate resins, vinyl chloride resins, butyral resins, vinyl chloride vinyl acetate polymers, polyurethane resins, fumaron resins, polyester resins, ethyl cellulose. It is preferable to use a coloring ink composed of a single or a plurality of synthetic resins such as nitrification cotton, cellulose acetate, and polyamide resin. Further, calcium carbonate, silica, barium sulfate, alumina, clay, shirasu balloon, talc, asbestine, magnesium carbonate, kaolin, and resin particles may be added to the colored ink, or a plurality of extender pigments may be added. As the solvent, hydrocarbon solvents such as toluene, benzene and xylene, alcohol solvents such as methanol, ethanol, iso-propyl alcohol and n-butyl alcohol, ketone solvents such as acetone, methyl ethyl ketone and methyl isobutyl ketone, Alternatively, an ester solvent such as ethyl acetate, butyl acetate, or cellosolve acetate may be used. The wood grain pattern layer 2 may be formed by a printing method such as a gravure printing method, an offset printing method, a screen printing method, a spray coating method, a flow coating method, a knife coating method, a gravure coating method, a roll coating method or a comma coating method. There is a coating method such as.

The grain base layer 3 is formed on the grain pattern layer 2. The wood grain base layer 3 is a layer for hiding the color of the base material, and can be composed of a layer made of an ink containing metal powder, a layer made of a metal thin film, a layer made of ink, and the like. The metal powder-containing ink layer is formed by adding resin and solvent to metal powder such as aluminum, zinc, nickel and brass, and a dispersant composed of a surfactant may be added if necessary. Aluminum is easy to handle as the metal powder, but is not particularly limited. In the case of aluminum, the wood grain base layer 3 is formed by using an ink in which aluminum powder or aluminum paste is dispersed and mixed in an appropriate resin and solvent. As the method for forming the wood grain base layer 3, printing methods such as gravure printing method, offset printing, screen printing method, spray coating method, flow coating method, knife coating method, gravure coating method, roll coating method and comma coating method are used. There is a coating method such as.

In this invention, since the color of the base material is concealed not by the base sheet 1 but by the wood grain base layer 3, when the type of the base material changes and the base material color changes, or Even if the surface color is partially different, the design expressed by the wood grain pattern layer 2 of the building material sheet is not affected, and the desired stable design expression is always obtained. be able to. Further, according to the present application, unlike the doubling method, even if the colorant is an organic pigment, the hiding property is not impaired, and thus the cost can be reduced.

A printing method is preferably used to form the wood grain pattern layer 2 and the wood grain base layer 3. According to the printing method, each layer can be continuously formed by one printing machine. Sequentially means that the base sheet 1 is unwound, the above layers are laminated in one step, dried and wound.

A protective layer 4 may be provided to protect the wood grain pattern layer 2 and the wood grain base layer 3 (see FIG. 2). The protective layer 4 is formed on the grain pattern layer 2 by a printing method. As the protective layer 4, polyethylene wax or the like may be used. Further, the protective layer 4 may also serve as the polyethylene wax, the resin, the solvent, and if necessary, the grain pattern layer 2 or the metal powder-containing ink layer. By providing the protective layer 4, the wood grain pattern layer 2 and the wood grain base layer 3 are not peeled off and the design is not damaged before the building material sheet is bonded to the base material. The protective layer 4 may be formed by a printing method such as a gravure printing method, an offset printing method, a screen printing method, a spray coating method, a flow coating method, a knife coating method, a gravure coating method, a roll coating method or a comma coating method. There is a law.

The building material sheet obtained by the present invention may have other configurations depending on the type of decorative pattern. For example, embossing may be performed after printing, or wiping may be performed in which a colored ink is printed in the recesses formed by embossing.

In this way, a building material sheet can be obtained. The building material sheet is used by attaching it to the base material. Examples of the base material include plywood, wood-based materials such as MDF, injection-molded products, synthetic resin-based materials such as extrusion-molded products, and metal-based materials such as iron, stainless steel, and aluminum.

To apply the building material sheet to the base material, there are cases where an adhesive is applied to the base material and then applied, and where the building material sheet is applied and applied. In general, when the base material is flat, the adhesive is applied to the base material, and when the base material is not flat, the adhesive is often applied to the building material sheet. A laminator, a multi-stage press, a lapping machine, a vacuum press, or the like can be used to bond the building material sheet to the base material.

Further, when it is possible to apply heat and pressure when the building material sheets are stuck together, an adhesive layer may be further provided on the building material sheet. As the adhesive layer, a heat-sensitive or pressure-sensitive resin suitable for the material of the base material is appropriately used. For example, if the base material is acrylic resin, acrylic resin may be used. When the material of the base material is polyphenylene oxide / polystyrene resin, polycarbonate resin, styrene copolymer resin, or polystyrene blend resin, acrylic resin, polystyrene resin, polyamide having affinity with these resins It is only necessary to use a system resin. Further, when the material of the base material is polypropylene resin, chlorinated polyolefin resin, chlorinated ethylene-vinyl acetate copolymer resin, cyclized rubber and coumarone indene resin can be used. When the material of the base material is wood or ceramic, chlorinated polyolefin resin, chlorinated ethylene-vinyl acetate copolymer resin, polyamide resin or the like may be used. Examples of methods for forming the adhesive layer include gravure printing, offset printing, screen printing, and other printing methods, spray coating, flow coating, knife coating, gravure coating, roll coating, comma coating, and the like. There is a coat method.
