たフイルムを貼合する方法に関する。Detailed Description of the Invention This invention provides a sheet or film made of an elastic body such as rubber, synthetic rubber, or polyurethane, and a sheet or film made of synthetic resin such as polyester or polypropylene, or cellulose derivatives such as cellulose acetate or nitrified cotton. The present invention relates to a method for laminating films that have been prepared.

著しく価値を低下する。 However, when attaching a synthetic resin film to a sheet or film that retains elasticity (e.g. natural rubber, synthetic rubber, polyurethane, etc.) using the above method, a severe curling phenomenon occurs and the value as a general commercial product decreases significantly. do.
本発明者はこの原因を探求したところ、下記の

本発明者は実験によつてこのカール現象をなく
する為には下記の２法があることを見出した。 The inventor investigated the cause of this and discovered that the curl phenomenon occurs due to the following reasons.
For example, when laminating a biaxially stretched polyester film to a synthetic rubber sheet, when the synthetic rubber sheet and polyester film are stacked and thermocompressed after applying an adhesive, the synthetic rubber stretches in the direction perpendicular to the pressure applied. Furthermore, when the pressure is removed after adhesion, the synthetic rubber shrinks to its original length, so that the adhered body curls significantly toward the synthetic rubber. In other words, the upper surface of the synthetic rubber bonded to the non-shrinking polyester film is prevented from shrinking, but the lower surface shrinks and attempts to restore itself, causing it to curve upward and deform. (See FIG. 5) Through experiments, the inventor found that there are two methods for eliminating this curling phenomenon.

的を達することは出来ない。従つてこの方法は
実用的な貼合方法でないことは明白である。(1) When applying the above synthetic rubber sheet and polyester film under harsh conditions (pressure and temperature) that cause the elastic limit of synthetic rubber, no curling will occur. However, in this case, the elasticity peculiar to synthetic rubber is completely lost, and the purpose of using the synthetic rubber sheet cannot be achieved. Therefore, it is clear that this method is not a practical bonding method.
(2) 上記合成ゴムの伸びない程度の圧力（合成ゴ

する。(2) Apply pressure to the extent that the synthetic rubber does not stretch (a pressure of 30 g/cm 2 to 300 g/cm 2 depending on the type of synthetic rubber, type of polyurethane, thickness, etc.) and use it for lamination. When using a two-component type adhesive, heat for 5 to 10 minutes at the curing temperature of the adhesive (10 to 20°C lower than the cure temperature, for example, 55 to 45°C if the cure temperature is 65°C).
この条件で処理すると接着剤のキユアの進行度

促す。 When processed under these conditions, the degree of curing of the adhesive is estimated to be about 20 to 40%. This is not 100% cured, so the adhesive layer has avatar-like unevenness all over the surface. However, in this state, the interface between the synthetic rubber sheet and the polyester has considerable adhesion, so if this semi-cured material is left at room temperature (2 to 24 hours), curing will progress gradually. encourage you to do so.
このものは最早やロール又はプレス等の外圧を

Glued. Therefore, there is no risk of curling in the bonded product as in the prior art, and a smooth and excellent product can be obtained.
