Abstract:
The invention provides a vulcanized rubber laminate obtained by firmly bonding an unvulcanized epichlorohydrin rubber layer and an organic peroxide-containing fluororubber layer. The laminate is obtained by thermal adhesion a layer of an unvulcanized epichlorohydrin rubber composition to a layer of an unvulcanized fluororubber composition. The epichlorohydrin rubber composition comprises 1) an unvulcanized epichlorohydrin rubber containing 3 to 15 mol % of allyl glycidyl ether unit, 2) quinoxaline-based vulcanizing agents, mercaptotriazine-based vulcanizing agents or bisphenol-based vulcanizing agents, and 3) 1,8-diazabicyclo(5,4,0)undecene-7 salts, 1,5-diazabicyclo(4,3,0)nonene-5 salts, quaternary ammonium salts, quaternary phosphonium salts, basic white carbons or an alkaline metal salt of higher fatty acid the fluororubber composition comprises an fluororubber and an organic peroxide-based vulcanizing agent.
