It is said that there is no durable bonding method for P-rubber, but cyanoacrylate (

ある。However, since cured cyanoacrylate forms an adhesive layer that is hard and has little elongation (elongation rate; % or less), is it possible to bend it greatly like rubber? When materials with special characteristics are bonded, fine cracks occur in the adhesive layer when the bonded structure is bent, making it difficult to maintain sufficient reliability. There is a problem of securing it.

着を行う方法である。How to bond BP rubber of the present invention to EP rubber? Install EEA as an adhesive at room temperature to the object to be bonded, and then heat the bonding hole to 700 to 750℃.
This is a method of bonding by heating to melt the EEA and returning it to room temperature.

10C9/10mm) VJEMAf is used, and the relationship between the heating temperature during adhesion and the adhesive strength (peel strength) σ] is shown. As shown in the figure, adhesive strength is developed at a heating temperature of about 70° C., but in order to obtain sufficient strength, it is necessary to increase the adhesive strength to ioo'c or higher. On the other hand, in a region where the heating temperature is 105 or higher, the additives of the EP rubber migrate to the adhesive layer (1:EA) and decompose or vaporize, resulting in a foaming phenomenon.

Since strength is obtained, there are no problems with processability or workability.
