Description

[Detailed description of the invention] The present invention relates to an interior material that is optimal as a wall material or ceiling material. To provide an interior material that can prevent large warpage, distortion, etc. on the board side caused by the large heat shrinkability of the plate.

An embodiment of the present invention will be explained below based on FIG. 1. The interior material of this embodiment consists of a hard synthetic resin substrate 1
A decorative board 3 made of foamed synthetic resin is heat-sealed to the surface 2 of the decorative board 3, and a lattice-like fiber mesh 4 is embedded over the entire surface of the decorative board 3.

The mesh body 4 is made of natural fibers (or glass fibers,
It is composed of warp yarns 4a and weft yarns 4b made of synthetic fibers. Further, the decorative board 3 is made of, for example, a polyvinyl chloride resin foam material. The substrate 1 has a connecting protrusion 6 protruding left and right outward over the entire length of one of the side walls 5a and 5b protruding toward the back surface 3a at the outer periphery of both ends of the substrate 1, A soft elastic claw 7 is formed at the upper end of the side wall 5a. A concave line 8 that fits into the convex line 6 along the entire longitudinal length of the other side wall 5b of the substrate 1.
A flange 9 is provided at the upper end of the side wall 5b. The interior material is attached to the ceiling 10 etc. by nailing the flange 9 and the rafter 10a of the ceiling 10 etc.

In the above configuration, the interior material is prepared by dipping the mesh body 4 in a liquid foamed synthetic resin material that is the material of the decorative board 3;
This is foamed to integrally mold the decorative board 3 with the net-like body 4, and then the decorative board 3 is thermally fused to the surface of the substrate 1. Then, since the warp yarns 4a and the weft yarns 4b of the net-like body 4 have a large resistance to contraction in the respective yarn directions, the net-like body 4 becomes less contractible due to the synergistic effect of both the yarns 4a, 4b. The heat shrinkage force of the decorative board 3, which has high heat shrinkability, is weakened, and warping and distortion of the substrate 1 can be prevented.

The two interior materials are connected by fitting the convex strips 6 on the side wall 5a of one substrate 1 to the concave strips 8 on the side wall 5b of the other substrate 1, and inserting the elastic claws 7 into the flanges on the other side wall 5b. This is done by applying pressure to 9.

Next, another embodiment of the present invention shown in FIG. 2 will be described. In this embodiment, a concavo-convex pattern 11 is provided on the surface of the decorative board 3, and the other configurations are the same as those of the above-mentioned embodiment.

In the above configuration, in order to form the uneven pattern 11 on the surface of the decorative board 3, liquid foamable vinyl chloride resin is applied to the surface of the decorative board 3 according to the convex pattern of the uneven pattern, and then the decorative board 3 is Heat at 180℃-200℃. Then, only the portion to which the resin liquid has adhered will foam, forming a convex portion 11a with a height of 1 to 30 mm. By printing a colored pattern on the convex portion 11a using a roller or the like, an interior material that is aesthetically pleasing and has a good feel can be completed.

As is clear from the above explanation, the present invention has a foamed synthetic resin decorative board heat-sealed to the surface of a hard synthetic resin substrate, and a lattice-shaped fiber board made of glass fiber or the like covering the entire surface of the decorative board. This invention relates to an interior material characterized in that a net-like body is embedded by integral molding, and the warp and weft threads of the net-like body are made of a material that has a high resistance to shrinkage in the respective thread directions.

Therefore, according to the present invention, since the warp and weft threads of the net have a large resistance to contraction in the respective thread directions, the synergistic effect of both yarns reduces the shrinkability of the net. Since the shrinkability of the lattice network is small, the heat shrinkage force of the highly heat-shrinkable decorative laminate can be reduced, and large warpage, distortion, etc. will occur on the board when it is cooled after heat-sealing the decorative laminate and the board. This can be prevented, and since the decorative board is made of foamed synthetic resin,
It can be expected to have excellent practical effects as an interior material, such as high heat insulation, good tactility on the decorative board surface, and the ability to easily create uneven patterns on the decorative board surface.
