約されている。“Prior Art” Conventionally, ethylene / propylene rubber (hereinafter referred to as EP rubber) is butyl rubber, nitrile rubber, chloroprene rubber,
Since it is superior in heat resistance and weather resistance to natural rubber and the like, it is widely used as an airtight O-ring and a watertight O-ring for automobiles, aircrafts, and communication equipment. In such a situation, it may be convenient if the O-ring can be repaired by bonding, for example, when the O-ring is damaged. However, since this EP rubber is difficult to bond, its application range is limited.
「発明が解決しようとする課題」 一般に、EPゴムの耐久性のある接着方法はないと言われ
ているが、一時的な接着にはシアノアクリレート（瞬間
接着剤）を用いることがある。[Problems to be Solved by the Invention] Generally, it is said that there is no durable adhesion method for EP rubber, but cyanoacrylate (instant adhesive) may be used for temporary adhesion.

る。However, the cured cyanoacrylate forms an adhesive layer that is hard and has a small elongation (elongation rate: 2% or less). Therefore, when a material characterized by being able to bend greatly like rubber is adhered, when the adhesive composition bends, There is a problem that fine cracks occur in the adhesive layer, and sufficient reliability cannot be ensured.

EE of 25 (wt%), mate index 5-10 (g / 10mm)
A is used and the relationship between the heating temperature at the time of adhesion and the adhesive strength (peel strength) is shown. As shown in the figure, the adhesive strength develops from a heating temperature of about 70 ° C., but it is necessary to set it to 100 ° C. or higher to obtain sufficient strength. On the other hand, the heating temperature is 1
In the region above 50 ℃, EP rubber additive is adhesive (EEA)
As it moves to and decomposes or vaporizes, a foaming phenomenon occurs.

い。Therefore, the heating temperature is appropriately in the range of 100 to 150 ° C. The heating time is 1 minute or less when measured from room temperature, and the pressure applied to the adhesive surface is several tens of g / cm 2 or less, so that sufficient adhesive strength can be obtained, so that there is no problem regarding workability or workability.

As shown in Fig. 2, an EP rubber O-ring 1a with an inner diameter of 100 mm and a cross-sectional diameter of 3 mm is cut once, and a 0.4 mm thick EEA thin plate 1b is cut on this cut surface.
Sample 1 was prepared by sandwiching and heating at 150 ° C. and adhering. Crush this into the test container shown in FIG.
%, Sealed with gas at 1 kg / cm 2 and heat cycled 100 times in the temperature range of −20 to + 60 ° C., but no gas leakage was observed and excellent airtightness was exhibited. This is because the EEA1b of the adhesive layer is soft and has a large elongation (300 to 700
%), And it is possible to follow the deformation when the O-ring 1a is crushed.
