Abstract:
1. A thermoplastic elastomer/rubber laminate comprising at least one rubber layer containing 100 parts by weight of a rubber and 0.1-20 parts by weight of an antioxidant preblended thereto and at least one thermoplastic elastomer composition layer, obtained by laminating at least two layers of the at least one rubber layer and the at least one thermoplastic elastomer composition layer, followed by heating and pressing, whereby the antioxidant migrates from the rubber layer to the thermoplastic elastomer composition layer to improve the weathering resistance, said antioxidant being selected from the group consisting of N-phenyl-N′-(1,3-dimethyl-butyl)-p-phenylenediamine and N-phenyl N′-isopropyl-p-phenylenediamine and said thermoplastic elastomer composition comprising (A) at least one resin selected from the group consisting of polyamide-based resins, polyester-based resins, polynitrile-based resins, polymethacrylate resins, vinyl acetate-based resins, polyvinyl alcohol, polyvinylidene chloride, polyvinyl chloride, fluorine-based resins and imide-based resins and (B) at least one elastomer selected from the group consisting of diene-based rubbers and the hydrogenates thereof, acryl rubbers, halogen-containing rubbers, silicone rubbers, sulfur-containing rubbers, fluorine rubbers and thermoplastic elastomers.
