[Structure] A thin veneer, plywood, or a substrate selected from MDF is attached to at least the upper surface of a base plate selected from flake board or oriented particle board, and a decorative veneer is applied to the upper surface of the substrate. The composite decorative board is formed by cutting and forming the joint processing part on the periphery.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a decorative board used for the interior of a house or the like, and more specifically, a decorative board that can be used as a floor material, a wall material, or a ceiling material using a flake board or oriented particle board as a base plate. Regarding

[0002]

[Prior art]

 Conventionally, the decorative board used for the interior of houses, etc. is made of plywood made from hardwood of South Sea timber as the base board from the viewpoints of workability, strength, price, etc. It is common that the surface coating such as resin is applied.

By the way, the supply of hardwood plywood is decreasing due to the policy of conserving southern hardwood, which is caused by the recent decrease in the hardwood of the southern wood, and the conventional veneer is inevitably forced to change its structure. In particular, since floorboards and concrete formwork, which use thick plywood as the base plate, use a large amount of wood, the species are changing from broad-leaved trees to coniferous trees of small diameter that are relatively easy to regenerate.

[0004]

[Issues to be solved by the device]

 However, coniferous trees have not only hard and soft parts juxtaposed within the veneer, but also many knots and numerous irregularities on the veneer surface. I couldn't replace it.

[0005] Therefore, it has been considered to use a particle board or a fibrous board, which has a stable supply amount even from the raw material side and has a uniform plate surface quality, as a base plate, but the expansion / contraction rate due to humidity change is higher than that of plywood. Large, low water resistance. Furthermore, even if it is attempted to cut and form a processing part for joining on the side surface, the strength etc. is inferior to plywood, so it was not a satisfactory base plate.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the decorative board of the present invention has a base plate selected from a flake board or an oriented particle board and a thin plate, plywood, or MDF. Provided is a composite decorative board having a decorative veneer attached to the upper surface of the substrate, and a bonding processing part cut and formed in the peripheral part.

[0007]

[Action]

 In the decorative board of the present invention, the flake board or the oriented particle board is used as the base plate because the whole board is constructed by adhering large chips, and therefore, in the case of plywood or oriented particle board having almost the same thickness. , Because it is stronger and more workable than plywood. Also, because a thin substrate is attached to the upper surface of the base plate, there are slight irregularities due to large flakes or strands on the surface of the flake board or oriented particle board. This is to obtain a smooth surface and improve the strength as a decorative plate. The purpose of attaching the decorative veneer to the upper surface of the substrate is for the purpose of surface makeup with natural wood.

Hereinafter, the present invention will be described with reference to the drawings illustrating an embodiment.

FIG. 1 is a perspective view of a composite decorative board according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line AA. Reference numeral 1 is a base plate, 2 is a substrate, 3 is a decorative veneer, 4 is a processing part for bonding, and 5 is a top coating.

The base plate 1 is a flake board or oriented particle board having a thickness of about 9 to 18 mm. A flake board is also called a wafer board. It is a particle board that is made by applying an adhesive to a large thin piece of adhesive and thermoforming it. An oriented particle board has the same elongated piece (strand) in the fiber direction. It is a particle board arranged in the direction.

The substrate 2 attached to the upper surface of the base plate 1 is a plate material selected from thin single plate, plywood, and MDF. The thickness of the substrate 2 is a plate material in the range of about 1 to 4 mm, and the thickness, rigidity and workability are such that the surface can be made flat by covering the slight unevenness present on the surface of the base plate 1. Any plate you have will do.

In addition, not only the upper surface but also the lower surface of the base plate 1 may be adhered with a plate material having a similar thickness, which may be useful for preventing the warp of the decorative plate.

A decorative veneer 3 is attached to the upper surface of the substrate 2. The decorative veneer 3 has a thickness of 0. It is a veneer sliced by a regular slicer or rotary lace of about 3 to 2 mm, and the veneer, cherry tree, zelkova, cedar, pine, cypress, and other so-called veneers are used as the tree species. .

As the adhesive used for attaching the substrate 2 and the decorative veneer 3 to the base plate 1, a thermosetting resin adhesive such as urea resin, melamine resin, phenol resin, or vinyl acetate resin, which is commonly used, Acrylic resin, rubber-based thermoplastic resin adhesive, etc. are used alone or in combination.

There is no particular limitation on the method of adhering each plate material, such as a heat pressure adhering method and a cold pressure adhering method.

The joining processing portion 4 formed by cutting around the composite decorative board is a conventional actual fruit, a little fruit, and a combination process, and is cut using a wood processing machine such as a processing board or a tenor. It is cut and formed.

[0017]

【Example】

 (Embodiment 1) A 2.5-mm-thick 3-ply lauan plywood is used as a substrate 2, and a 0.3 mm-thick beech veneer as a decorative veneer 3 is attached to the surface of the veneer-plywood-based vinyl acetate resin. An adhesive was used to perform cold pressure bonding to the surface of the base plate 1 of the wafer board having a thickness of 12 mm. At this time, a plywood of the same thickness was also adhered to the back surface of the base plate 1 as a backing material.

Then, the decorative plate was cut into a predetermined size, and then a peripheral part of the side was subjected to a true 4 process for bonding using a wood processing board. Finally, a transparent urethane resin paint 5 was applied from the surface of the decorative veneer 3 to obtain the desired composite decorative plate.

Example 2 A strand-oriented particle board having a thickness of 15 mm was used as a base plate 1, a lauan veneer having a thickness of 1.5 mm was provided on the upper surface of the substrate 2, and a cherry having a thickness of 0.3 mm was provided on the surface thereof. The veneer was used as a decorative veneer 3 by hot pressing using a urea resin adhesive to produce a decorative veneer. At this time, a single plate having a thickness of 1.5 mm was also adhered to the back surface of the base plate 1 as a backing material.

Next, the decorative plate was cut into a predetermined size, and then the peripheral part of the side was subjected to a bonding process 4 process. Finally, a transparent urethane resin paint 5 was applied from the surface of the decorative veneer 3 to obtain the desired composite decorative plate.

[0021]

[Effect of device]

 According to the decorative board of the present invention, since a flake board or oriented particle board, which is composed of chips of almost uniform size to the inside, is used as a base plate, even if a processing part for bonding is cut and formed in the peripheral side part. As well as being durable enough to be used, the base plate has strength and workability comparable to that of plywood having almost the same thickness.

Since a thin substrate is attached to the upper surface of the base plate, it is possible to obtain a smooth surface by covering the slight irregularities due to the flakes and the strands existing on the surface of the base plate. Not only that, the strength of the decorative plate can be improved.

Since the decorative veneer is attached to the upper surface of the substrate, a beautiful decorative veneer made of natural wood can be obtained.

Further, since the peripheral portion of the decorative plate is processed for joining, the same construction method as that of the conventional plywood-conformable decorative plate can be adopted and the construction is easy.
