PROCESS FOR PRODUCING VULCANIZED RUBBER/THERMOPLASTIC RESIN COMPOSITE

WIPO Patent Application WO/2002/022719

A1

A process for producing vulcanized rubber/thermoplastic resin composites which comprises using a mold having a cavity for vulcanized-rubber molding holding and a cavity for resin molding formation, placing a vulcanized rubber molding prepared beforehand in the cavity for vulcanized-rubber molding holding, and injecting a molten thermoplastic resin into the cavity for resin molding formation to form a resin molding, characterized by forming a vulcanizable adhesive layer (A) consisting mainly of chlorosulfonated polyethylene on that surface of the vulcanized rubber molding which is to be bonded to the thermoplastic resin, subsequently forming an adhesive layer (B) consisting mainly of a phenolic resin, and then injecting the thermoplastic resin. By the process, a vulcanized rubber/thermoplastic resin composite in which the vulcanized rubber molding has been tenaciously bonded to the thermoplastic resin can be produced with satisfactory productivity.
