〔産業上の利用分野〕
本発明は、建材や家具材等に適した化粧板の製造方法に
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing a decorative board suitable for building materials, furniture materials, and the like.

口部分あるいは木口近くでまだら状に生じる場合が多く
、不均一な外観を呈し、製品価値を低下させる。Traditionally, in order to manufacture decorative laminates, resin-impregnated veneers are arranged on the surface of the base material so that their edges are butt-to-edge, and then heat-pressed to harden the resin impregnated into the veneer and bond it to the base material. In the above method, a method in which adhesives are used to bond to the base material at the same time is known. [Problem to be solved by the invention] The disadvantage is that gaps and overlaps tend to appear at the joints of resin-impregnated veneers. Furthermore, the resin impregnated into the veneer leaks out from the end surface of the veneer during hot pressing, resulting in a phenomenon called "whitening" in which the leaked part becomes white. This whitening phenomenon often occurs in a mottled manner at or near the butt end, giving an uneven appearance and reducing product value.
本発明は上記欠点を除くことを目的とし、化粧板表面の
単板のジヨイント部における隙間や重なり、あるいは白
ぬけによる外観上の欠点をもたない美麗な化粧板を得る
ことができる化粧板の製造方法を提供するものである。The present invention aims to eliminate the above-mentioned drawbacks, and is a decorative board that can obtain a beautiful decorative board that does not have any defects in appearance due to gaps, overlaps, or white spots in the joints of the veneers on the surface of the decorative board. A manufacturing method is provided.

ように帯状材を重ねておいて加熱、加圧することにより
、上記問題点を解決しようとするものである。The present invention provides a method for manufacturing a decorative board in which resin-impregnated veneers are arranged in a pattern and the resin is cured by heating and pressurizing the resin-impregnated veneers. The above-mentioned problem is attempted to be solved by stacking them and heating and pressurizing them.
基材としては、合板、パーティクルボード、中質繊維板
、けい酸カルシウム板等が用いられる。As the base material, plywood, particle board, medium density fiberboard, calcium silicate board, etc. are used.
単板としては、このような基材の表面に化粧効果を目的
として接着する化粧単板であれば任意のものが用いられ
る。As the veneer, any decorative veneer can be used as long as it is a decorative veneer that is adhered to the surface of such a base material for the purpose of cosmetic effect.
単板に含浸させる樹脂を例示すると、ポリエステル樹脂
、メチルメタクリレート樹脂、メラミン樹脂等がある。Examples of resins to be impregnated into the veneer include polyester resin, methyl methacrylate resin, and melamine resin.
このような樹脂を含浸させた単板を、基材表面へ載置す

配置する。In order to place a veneer impregnated with such a resin on the surface of a base material, 1. 2. How to match comrades Kiguchi, 2. How to overlap comrades Kiguchi, 3. There are ways to leave a slight gap between the boards, and these methods allow you to arrange the veneers in a parquet or checkerboard pattern.
本発明で用いる帯状材は、樹脂含浸帯状単板であれば、

じ使用することができる。If the strip material used in the present invention is a resin-impregnated strip veneer,
In addition to the advantage of being able to compensate for the insufficient resin content,
This material is suitable because it has good adhesion to the resin-impregnated veneer, but other materials such as suitably colored resin-impregnated paper or thin melamine resin-impregnated paper laminates can also be used. However, the band material is not limited to the resin-impregnated band material, and veneer, thin paper, etc. that are not impregnated with resin can also be used as necessary.

。As shown in Figure 1, when such a strip material is layered on top of the joint part of a resin-impregnated veneer so as to hide it and cured under heat and pressure using a means such as a hot press, a beautiful decorative board is created. is obtained. In addition, in the case shown in FIG. 1, from a design point of view, a similar strip material is placed around the decorative board, but the surrounding strip material may not be placed.
この場合、樹脂含浸単板が含浸樹脂により基材への接着

同時に基材への接着も行われるが、そうでない場合は、
尿素樹脂系接着剤やウレタン系接着剤等の接着剤を介し
て単板と基材との接着を行えばよい。In this case, if the resin-impregnated veneer has adhesive properties to the base material due to the impregnated resin, adhesion to the base material will be performed at the same time as the resin hardens using only heat pressure, but if this is not the case,
The veneer and the base material may be bonded together using an adhesive such as a urea resin adhesive or a urethane adhesive.
第２図に、樹脂含浸単板を隙間をあけて基材上に載置し

状材を置き熱圧した場合の例を示す。Figure 2 shows an example in which resin-impregnated veneer is placed on a base material with a gap, and a strip material is placed in the gap to cover it and heat-pressed. An example is shown in which the butt ends of veneers are placed one on top of the other, and a band material is placed in the overlapped area to hide it and hot-pressed.
