[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a decorative plate used as a wall plate, a ceiling plate, a door of a storage furniture, a side plate, a top plate or the like.

[0002]

[Prior Art]

 Conventionally, wood-based decorative boards used for wall boards, ceiling boards, doors of storage furniture, side boards, top boards, etc. have been mainly made of natural wood. However, it became difficult to obtain natural wood, and even if it could be obtained, it was quite expensive.

Therefore, as an alternative to the conventional decorative board, a flash in which a core material made of plywood or fiber board is combined into a rectangular shape to form a frame material, and a thin plywood sheet having a decorative sheet adhered to the surface is fixed to the frame material. Structural veneers are now offered.

Such a flash-structured decorative plate has a hollow interior and thus is light in weight, but is too light and lacks a high-class appearance. In addition, the flash structure requires a lot of work because the core material is combined, and there is a problem that the cost is increased due to an increase in personnel cost.

[0005]

[Problems to be solved by the device]

 Therefore, nowadays, there is provided a decorative board having a particle board as a substrate and a decorative sheet attached to the surface thereof. However, although this veneer was satisfactory in terms of weight, it was heavy, which caused problems such as making buildings taller and making it difficult to transport them to construction sites on higher floors.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and its configuration has a specific gravity of 0. Provided is a decorative board in which a wood-based surface material having a higher specific gravity than that of the wood substrate is adhered to the upper surface of the wood substrate in the range of 3 to 0.4, and a decorative sheet is attached to the surface of the surface material. It was solved by

[0007]

[Function of the device]

 In the decorative board of the present invention, a wood-based surface material having a higher specific gravity than the wooden board is attached to the upper surface of the wooden board having a specific gravity in the range of 0.3 to 0.4. This is because it is a decorative board that is lightweight and has no strength. Also, by using natural wood for the substrate, it is possible to improve the overall strength and to impart wood screw holding force to the decorative plate.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view of a decorative plate according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA, and FIG. 3 is a sectional view of a decorative plate according to another embodiment.

【Example】

 As the substrate 1, a wood-based substrate having a specific gravity of 0.3 to 0.4 is used. Specific gravity 0. Although the substrate 1 of 3 to 0.4 has a light weight, the material 2 itself is porous and is not suitable as a base material for sticking the decorative sheet 3 on the surface because it causes defects such as recesses on the surface of the decorative sheet 3. Is. Also, since it has low hardness, it is easily dented by external pressure.

Therefore, the surface layer material 2 having a higher specific gravity than the substrate 1 is fixed to the upper surface of the substrate 1. When the specific gravity of the surface layer material 2 is about 0.4 or more, there are few recesses on the surface as a base material to which the decorative sheet is attached, and the surface of the decorative sheet 3 to be attached is less affected.

In the embodiment of the present invention, a laminated wood of natural wood (tree species name: Falcata specific gravity 0.34) was used as the substrate 1. This natural wood has a certain level of strength for use as a material for construction materials, is lightweight, and cannot be used as a structural material, so it is relatively easy to obtain. In addition to the laminated wood of this embodiment, the substrate 1 can be made of natural wood such as plywood or plywood, which is satisfactory in terms of strength and weight. Further, MDF (specific gravity 0.7) was used as the surface layer material 2 in this example, but since this MDF has a uniform material, has few voids, and has hardness, it can be used as a base material for a decorative plate. Is good.

In this way, after the surface layer material 2 having a higher specific gravity than the base plate 1 is fixed to the upper surface of the wooden board 1 having a specific gravity in the range of 0.3 to 0.4, the surface portion is # 100. After polishing at the 240th position, the decorative sheet 3 is attached via an adhesive.

As the decorative sheet 3, titanium paper, thin paper, mixed paper, precoated paper, ordinary cosmetic paper, natural wood veneer, synthetic resin sheet, or the like is used.

The adhesive to be used is a thermosetting synthetic resin such as urea resin, melamine resin, benzoguanamine resin or the like, or a vinyl acetate resin adhesive, or a thermoplastic resin adhesive such as a vinyl acetate emulsion adhesive, alone or in an appropriate mixture. To use. If the decorative sheet 3 to be attached is resin-impregnated paper, the resin adhered to the impregnated paper is used, so an adhesive is not always necessary. If the decorative sheet 3 is made of a synthetic resin sheet such as a vinyl chloride resin sheet and cannot be pressed at high temperature, a modified vinyl acetate emulsion adhesive or the like may be used.

Adhesion of the decorative sheet 3 is performed by placing the decorative sheet 3 on the surface of the surface layer material 2 with an adhesive and then using a hot press or a cold press.

The decorative plate as shown in FIG. 2 was obtained as described above. Incidentally, FIG. 3 shows another embodiment in which the surface layer material 2 is fixed to the front and back surfaces of the substrate 1, and the decorative sheet 3 is further adhered to the surface of the surface layer material 2 on the front and back surfaces.

[Effect of the device]

 As described above, the decorative board of the present invention uses a wood-based board having a specific gravity in the range of 0.3 to 0.4. Light weight makes it easy to transport. Moreover, when natural wood is used for the wood-based substrate, it is lightweight but strong enough that it will not crack or break during transportation. Furthermore, since the wood-based board is also excellent in holding power for wood screws and the like, it is possible to impart holding power for wood screws and the like to the entire decorative board. On the other hand, since the surface material that has a higher specific gravity than the wooden board is used for the upper surface, the hardness of the surface of the decorative board is improved, so the surface does not easily dent due to external pressure. Since the surface material is fixed to the upper surface of the wooden board, the wooden board can be used even if it is not a good tree, so it is economical. Furthermore, when a fiberboard such as MDF is used as the surface material, the surface material is uniform, so that the effect of uneven color and unevenness of the surface material as the base material can be prevented in advance. ..
