  • Method for producing rubber-resin composite
    Patent number: 6620517
    Abstract: A method of producing a rubber-resin composite whose vulcanized rubber and thermoplastic resin moldings are bonded together by high adhesive strength at low cost, satisfying both moldability and mechanical strength. It comprises: (1) making the vulcanized rubber molding by vulcanization molding, (2) forming an adhesive layer, whose principal ingredient is chlorosulfonated polyethylene, on a surface of the rubber molding to be bonded to the resin, and (3) while arranging the rubber molding in a mold, pouring the thermoplastic resin containing 30˜60 wt. % of glass fiber in a molten state into the mold to form the resin molding.
    Type: Grant
