トが付着するため、型枠を何度も利用することが
難しく、無駄が多かつた。 Many thick plywood boards are used in concrete formwork, but these do not peel easily from the concrete.
The disadvantage was that the concrete surface was extremely rough after the formwork was removed. Furthermore, since concrete adhered to the formwork, it was difficult to use the formwork over and over again, resulting in a lot of waste.

〜10：90の範囲内が望ましい。 In the invention of this application, the board refers to plywood, particle board, hardboard, etc. Common thermosetting adhesives include urea resin, urea melamine resin, and phenol resin. Hot melt adhesives include base polymers such as ethylene/vinyl acetate copolymer resin (EVA), polyethylene resin, polypropylene resin, and polyamide resin, rosin resins and terpene resins as tackifiers, and paraffin wax as wax. , a synthetic wax such as polyethylene wax is used. In addition, in the present invention, the mixing ratio of thermosetting adhesive and hot melt adhesive is 90:10.
~10:90 is desirable.

造できるのである。 What is important about this invention is that an adhesive that is a mixture of a thermosetting adhesive and a hot melt adhesive is used, and that when the pressure is released, the pressure is released to atmospheric pressure or close to it, and then the adhesive is hot-pressed again. It is. This covers the following drawbacks:
Generally, when sheets are bonded by heat and pressure to the surface of plywood using an adhesive, when the pressure is released, the adhesive and moisture inside the plywood rapidly expands as water vapor and tries to escape, reducing the adhesive strength. The weak part of the adhesive will cause the adhesive to peel off. Therefore, that part becomes a defect of the product. However, as in this invention, when sheets are bonded together by thermo-pressure using an adhesive that is a mixture of a thermosetting adhesive and a hot-melt adhesive, once the pressure is released to atmospheric pressure or near atmospheric pressure, the above-mentioned drawbacks occur. Even if this occurs, if you heat-press it again, the hot melt adhesive will cause the peeled sheet to adhere.
This makes it possible to manufacture resin sheet overlay plates without poor adhesion.
なお、接着剤は合板表面に塗布してもよいし、
シート裏面に塗布してもよい。また合板製造と同
時にシートを接着してもよい。 Note that the adhesive may be applied to the plywood surface, or
It may also be applied to the back of the sheet. Alternatively, the sheets may be bonded together at the same time as the plywood is manufactured.
以下、本発明をその実施例を挙げ詳細に説明す
る。 Hereinafter, the present invention will be described in detail with reference to examples thereof.

その後解圧して所望の製品を得た。Example 1 A polypropylene sheet coated with an adhesive mixture of urea resin adhesive and hot melt adhesive at a ratio of 70:30 on the back side of 12 mm thick plywood and dried was placed on the surface and a pressure of 8 kg/cm 2 was applied. , heat-pressed at a temperature of 130°C for 2 minutes, then once depressurized to atmospheric pressure, and then heat-pressed again at a pressure of 2 kg/cm 2 and a temperature of 130°C for 20 seconds,
Thereafter, the pressure was decompressed to obtain the desired product.

実施例１と同様にして所望の製品を得た。Example 2 In Example 1, the thermopressure method was initially carried out at a pressure of 8
Kg/cm 2 and a temperature of 130℃ for 1 minute, then a pressure of 4Kg/cm 2 and a temperature of 130℃ for 1 minute, and then depressurized to near atmospheric pressure, then a pressure of 3Kg/cm 2 and a temperature of 130℃.

バーレイ板材を製造することができる。 When sheets are bonded by heat and pressure using an adhesive that is a mixture of thermosetting adhesive and hot melt adhesive, once the pressure is released to atmospheric pressure or near atmospheric pressure, parts with weak adhesive strength will cause the adhesive to peel off. Even if such a defect occurs, if hot-pressing is performed again, the peeled sheets will be bonded together by the action of the hot melt adhesive, and a resin sheet overlay plate material with no adhesion defects can be manufactured.
