Abstract
Regarding the bonding mechanism between metal and rubber, the detail has not yet been demonstrated. We have studied the changes of adhesive force in the proceeding of vulcanization reaction. And the results were as follows:- in the case of slow vulcanization rates, the adhesive force was proportional to compounded sulfer. But in the case of rapid vulcanization rates, a large amount of compounded sulfer was consumed for the vulcanization reaction, therefore the adhesive force was comparatively low. Also the increase rates of adhesive force per unit sulfer which corresponds to the increase rates of rubber strength was proportional to its rubber strength.
On the other hand, regarding the coating, a large difference of the adhesive force between copper and bronze coating was not recognized, and the adhesive force of brass coating by diffusion was considerably low.
