(産業上の利用分野)
本発明は、合板、石綿板等の基材の表面に貼着する化粧
仮に関するしのである。Detailed Description of the Invention 3. Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a decorative temporary adhered to the surface of a base material such as plywood or asbestos board.
(従来技術とその問題点)
従来、合板、石綿板等のH財の表面に化粧紙を貼着して
、ホットプレスで熱圧成型後、化粧紙上にポリエステル
樹脂を塗布し、さらにこの上にビニロンのフィルムを貼
合せて、常温硬化をさせて形成したポリエステル化粧合
板が公知である。(Prior art and its problems) Conventionally, decorative paper is pasted on the surface of H goods such as plywood or asbestos board, and after hot press molding, polyester resin is applied on the decorative paper, and then a polyester resin is applied on top of this. Polyester decorative plywood formed by laminating vinylon films and curing at room temperature is known.
この化粧合板は、上述のように合板をベースにして製品
が形成されているため、曲げ加工を施し難く、また当初
から曲面からなる合板を用いるとポリエステル樹脂を均
一に塗布できないので、平板状のものしか製造できず、
形状面での意匠性に欠けるという問題があった。As mentioned above, this decorative plywood product is formed based on plywood, so it is difficult to bend it, and if the plywood has a curved surface from the beginning, it will not be possible to apply polyester resin uniformly, so it is difficult to bend it. We can only manufacture things;
There was a problem in that it lacked design in terms of shape.
これに対して、合板のような基材とは別個に製品を作る
ようにしたメラミンあるいはDAP等のシート状の化粧
板が公知である。この化粧板は、それ自体で完成品とし
て形成された後、化粧用として合板1石綿板等の表面に
貼着される。そして、合板にこの化粧板を貼着したもの
は、上記化粧合板と同様の製品となり、またこの化粧合
板と同様に自由に曲げ加工を施すことができない状聾に
なるが、この化粧板自体が完成品であるので、曲面加工
はより容易になっている。すなわち、合板、石綿板等の
基材を予め曲面形状にしておいて、これに沿って化粧板
を貼着することにより、最終製品を曲面形状のものに形
成することができる。On the other hand, sheet-like decorative laminates such as melamine or DAP are known, which are manufactured separately from a base material such as plywood. After this decorative board is formed as a finished product by itself, it is attached to the surface of plywood 1, asbestos board, etc. for decorative purposes. When this decorative board is attached to plywood, it becomes a product similar to the above-mentioned decorative plywood, and like this decorative plywood, it cannot be bent freely and becomes deaf, but this decorative board itself is Since it is a finished product, it is easier to process curved surfaces. That is, by making a base material such as plywood or asbestos board into a curved shape in advance and pasting the decorative board along the curved shape, the final product can be formed into a curved shape.
しかしながら、この化粧板を上記基材に貼着するために
は、基材に接着剤を塗布して、この上に化粧板を貼り合
せた後、これらを加熱硬化させなければならない。この
ため合板に貼着する段階でホットプレスおよび表面平滑
用の鏡面板が必要となり、製造設備が大がかり、かつ高
価なものになるとともに、製造作業も複雑になっている
。However, in order to attach this decorative laminate to the base material, it is necessary to apply an adhesive to the base material, bond the decorative laminate thereon, and then heat and cure the adhesive. For this reason, a hot press and a mirror plate for surface smoothing are required at the stage of adhering to plywood, making manufacturing equipment large-scale and expensive, and manufacturing operations also complicated.
また、このような事情から、この化粧板は少ロット生産
用としては適しておらず、製品の種類は少なくせざるを
得ない。Furthermore, due to these circumstances, this decorative board is not suitable for small-lot production, and the variety of products must be reduced.
さらに、化粧板は、その材質および厚みをあまり小さく
できない(最少厚み、約0 、5 mm)ことに起因し
て、可撓性、伸び率が十分でなく、曲率が大きい曲げ加
工用としては使えず(最小曲率半径的5 mm)、この
化粧板が使える曲面形状は限られたものである等の問題
があった。Furthermore, due to the material and the fact that the thickness cannot be made very small (minimum thickness: approximately 0.5 mm), decorative boards do not have sufficient flexibility or elongation, making them unusable for bending processes with large curvatures. (minimum radius of curvature of 5 mm), there were problems such as the curved surface shape to which this decorative board could be used was limited.
(発明の目的)
本発明は、上記従来の問題点に鑑みてなされたもので、
その目的は製造工程の単純化、厚みの減少および曲面加
工を容易にすることを可能とじた化粧板を提供すること
にある。(Object of the invention) The present invention has been made in view of the above-mentioned conventional problems.
The purpose is to provide a decorative board that can simplify the manufacturing process, reduce thickness, and facilitate curved surface processing.

製品を容易に作ることができる。(Effects of the Invention) As is clear from the above description, according to the present invention, a base sheet layer is formed by adhering and impregnating acrylic amino alkyd resin on kraft paper or base paper, and an adhesive layer on this base sheet layer. The decorative paper layer is laminated onto the base sheet layer via the adhesive layer, and the polyester resin layer is coated on the decorative paper layer and cured at room temperature. Since the polyester resin layer is formed by curing at room temperature in this manner, the manufacturing process is simple and suitable for small loft production, making it possible to easily produce products that meet the needs of various users.
