BONDING OF RUBBER

摘要

PURPOSE:To impart a high adhesion strength to a rubber molding and an object to be bonded without giving any heat hysteresis by bonding the rubber molding on the object after a reactive pretreating agent is transferred on the surface thereof by a heat/pressure molding with a metal mold coated with the agent on the inner surface thereof. CONSTITUTION:A rubber material (e.g. urethane rubber and chloroprene rubber) fills a molding metal mold coated on the inner surface thereof with a reactive pretreating agent and molded by heating under a pressure to transfer the pre- treating agent onto the surface of a rubber molding. An object to be bonded such as metal member is bonded to the surface of the rubber molding with an epoxy adhesive or the like. EFFECT:No special treating process is required at the time of the primer process.
