Vulcanized rubber laminate

A vulcanized rubber laminate obtained by thermal adhesion a layer of (A) an unvulcanized epichlorohydrin rubber composition to a layer of (B) an unvulcanized fluororubber composition, wherein

• (A) the unvulcanized epichlorohydrin rubber composition consists of:
• (1) 100 parts by weight of an unvulcanized epichlorohydrin rubber containing an allyl glycidyl ether unit, or an unvulcanized epichlorohydrin rubber blend including at least an unvulcanized epichlorohydrin rubber containing an allyl glycidyl ether unit, the mole ratio of the unit to the total of the rubbers being 3 to 15 mol %,
• (2) 0.3 to 5 parts by weight of a vulcanizing agent selected from the group consisting of quinoxaline-based vulcanizing agents, thiourea-based vulcanizing agents, bisphenol-based vulcanizing agents or a mixture thereof, and
• (3) 0.1 to 5 parts by weight of a compound selected from the group consisting of 1,8-diazabicyclo(5,4,0)undecene-7 salts, 1,5-diazabicyclo(4,3,0) nonene-5 salts, quaternary ammonium salts, basic white carbons, and alkaline metal salts of higher fatty acids or a mixture thereof, with the proviso that the content of the basic white carbons is 0.1 to 30 parts by weight,
• (4) 0.5 to 50 parts by weight of an acid acceptor,
• (5) 0 to 10 parts by weight of a vulcanization accelerator,
• (6) 0 to 10 parts by weight of a vulcanization retardant, and
• (B) the unvulcanized fluororubber composition comprises 100 parts by weight of an unvulcanized fluororubber and 0.1 to 10 parts by weight of an organic peroxide-based vulcanizing agent.
