Abstract:
1. A hydrogenated nitrile rubber-metal laminate, which comprises a metallic sheet having opposite surfaces which metallic sheet has been subjected to a hexavalent ions-free chemical conversion treatment, a defatting treatment, a surface-roughening treatment, a primer treatment, or a combination of the recited treatments, and an adhesion layer and a rubber layer successively laid on one or both of the opposite surfaces of the metallic sheet, the rubber layer being a vulcanizate of a hydrogenated nitrile rubber compound comprising 100 parts by weight of a hydrogenated nitrile rubber having an iodine value of 10-15, 50-250 parts by weight of an inorganic filler containing 5-20% by volume, on the basis of total hydrogenated nitrile rubber compound, of calcium carbonate as a non-reinforcing inorganic filler having an average particle size of 0.01-2 μm, 2-10 parts by weight of N, N′-m-phenylene dimaleimide and 4-20 parts by weight of an organic peroxide.
