    摘要: A hydrogenated nitrile rubber-metal laminate, which comprises a metallic sheet subjected to a hexavalent Cr ions-free chemical conversion treatment, a defatting treatment, a surface-roughening treatment, a primer treatment, or a combination of the treatment, and an adhesive layer and a rubber layer successively laid on one or both surfaces of the metallic sheet, wherein the rubber layer is a vulcanizate of a hydrogenated nitrile rubber compound comprising 100 parts by weight of a hydrogenated nitrile rubber, 50-250 parts by weight of an inorganic filler containing not more than 20% by volume, on the basis of total compound, of a non-reinforcing inorganic filler having an average particle size of not more than 5 µ m, 4-20 parts by weight of an organic peroxide, and preferably furthermore 2-10 parts by weight of N,N' -phenylene dimaleimide. The rubber-metal laminate has a vulcanized rubber layer(s) distinguished in the heat resistant at elevated temperatures of 150°C or higher, the heat bending resistance, e.g. at 200°C for 100 hours, and the rubber bulging resistance (rubber flow resistance) when used at elevated temperatures and surface pressures.
