Description

[Detailed description of the invention] This invention relates to the improvement of decorative laminates mainly used for building materials such as wall materials, wainscoting materials, and ceiling boards.

Conventionally, this type of decorative board is made by laminating a thin metal layer such as aluminum foil on the surface of a plate-like base material such as board material or synthetic resin material to give a decorative surface finish. Some methods are used, such as direct printing to form a decorative surface or painting to create a decorative finish.
In either case, if the decorative surface is very thin and grooves are made for surface decoration, it will be necessary to groove the plate-like base material as well.This will damage the plate-like base material, which is a strength component, and reduce the strength of the decorative board. There are drawbacks that seriously impair the

With this idea, even if a recess is formed on the surface by making grooves for surface decoration, the bottom of the recess does not reach the plate-like base material, and therefore the plate-like base material mainly acts as a strength component. The purpose is to provide a decorative board that does not damage the wood and does not affect the overall strength of the decorative board.

To explain this invention in detail with reference to the illustrated embodiment, numeral 1 indicates a plate-like base material, and aluminum sheets or foils are applied to both sides of a substrate 11 such as a synthetic resin plate to provide water resistance and flame retardance. It is constructed by laminating thin metal layers 12a and 12b.

This plate-shaped base material 1 acts as a strength component,
Any material that acts as a strength component, such as a synthetic resin board or plywood, may be used, and it may be a composite material made by laminating thin metal layers as described above, or a single material.

Then, for the plate-shaped base material 1, a thin resin intermediate layer 2 made of a thermoplastic synthetic resin such as ABS resin or polyvinyl chloride resin is laminated to an appropriate thickness on the surface of the metal thin layer 12a on one side. Furthermore, a decorative board 10 is formed by laminating a thin plate or thin leaf-shaped decorative material 3 such as a decorative thin board (plated board), decorative paper, or decorative leather on the surface of the interlayer resin intermediate layer 2.

As described above, this decorative board 10 has a shape in which the decorative material 3 is polymerized and laminated on the plate-like base material 1 via the synthetic resin intermediate layer 2, so it is grooved for surface decoration. However, even if the decorative material 3 on the surface is in a thin layer, the resulting decorative recesses (grooves) 4 remain within the threatening resin intermediate layer 2, and the surface of the plate-like base material 1 (thin metal sheet) remains at its depth. There is no risk of causing a type of scratch that would not reach the layer 12a or the surface of the substrate 11 and damage the strength of the plate-like base material.

Note that the decorative material 3 can be made of water-resistant, non-flammable, corrosion-resistant materials, and the same material as the decorative material 3 can be widely used for the base material 11, so the applications of the decorative board 10 are extremely wide. It is wide-ranging.

As described above, according to this invention, even if the surface of the decorative board is processed such as grooving (grooving) for a decorative finish and a recess is formed, there is no difference between the decorative material and the plate-like base material. The synthetic resin intermediate layer laminated on the surface prevents the bottom of the recess from reaching the plate-like base material, and allows grooves etc. to be formed on the surface of the decorative material without impairing the strength of the plate-like base material, which mainly acts as a strength component. You can carve recesses for cosmetic purposes.

If the thickness of the synthetic resin intermediate layer is increased, the recesses can be carved deeper accordingly, making it possible to freely carve out recesses with a three-dimensional effect, which is effective for cosmetic effects.

Claims (1)

[Scope of utility model registration request] A thin plate or thin leaf-shaped decorative material is polymerized on at least one side of a plate-like base material that mainly acts as a strength component, with a synthetic resin intermediate layer interposed therebetween, and recesses are formed on the surface of the decorative material by grooving or the like. A decorative board characterized in that the bottom of the recess is fixed inside the synthetic resin intermediate layer.
