Abstract:
A rubber laminate comprising:a rubber composition (A), obtained by blending 0 to 120 parts by weight of zinc methacrylate and an organic peroxide into a total of 100 parts by weight of rubber ingredients including at least 40 parts by weight of an ethylenic unsaturated nitrile conjugated diene type highly saturated rubber in which the content of conjugated diene units in the polymer chain is not higher than 30% by weight, and a sulfur vulcanizable diene-based rubber composition (B) bonded by vulcanization through a bonding rubber composition (C), wherein the bonding rubber composition (C) is comprised of 100 parts by weight of a rubber containing 50 to 85 parts by weight of at least one type of diene-based rubber selected from a group consisting of natural rubber, polyisoprene rubber, polybutadiene rubber, and a conjugated diene-aromatic vinyl copolymer; 15 to 50 parts by weight of an ethylenic unsaturated nitrile-conjugated diene-based high saturation rubber in which the content of conjugated diene units in the polymer chain is not higher than 30% by weight; 10 to 60 parts by weight of zinc methacrylate, 0.3 to 10 parts by weight of an organic peroxide; and 5 to 50 parts by weight of a co-cross-linking agent having one of an acryl group, methacryl group, and allyl group wherein the co-cross-liking agent is liquid at room temperature.
