摘要:
Provide a laminate constituted by epichlorohydrin rubber layer and fluororubber layer that are strongly vulcanization-bonded together. A rubber laminate constituted by vulcanization-bonding an epichlorohydrin rubber layer that contains at least (a) magnesium oxide, (b) polythiol vulcanizing agent, (c) at least one type of compound selected from 1,8-diazabicyclo (5,4,0) undecene-7,1,5-diazabicyclo (4,3,0) nonene-5, and salts thereof, (d) at least one type of compound selected from organic phosphonium salts and organic ammonium salts, and (e) maleic anhydride modified polybutadiene, and a fluororubber layer; wherein such rubber laminate is characterized in that: the content of the polythiol vulcanizing agent (b) in the epichlorohydrin rubber layer is 0.3 to 1.2 parts by weight per 100 parts by weight of the epichlorohydrin rubber; and the content of the maleic anhydride modified polybutadiene (e) in the epichlorohydrin rubber layer is 0.3 to 1.5 parts by weight per 100 parts by weight of the epichlorohydrin rubber.
