(57) [Summary] [PROBLEMS] To provide belts, tires, and the like having high adhesiveness to metal, high modulus, high set resistance and high heat resistance. Provided is a rubber composition that can be suitably used for a composite of a rubber and a metal such as a roll or a mold, particularly a composite rubber product of a brass (brass) or bronze-plated steel sheet. SOLUTION: (1) 100 parts by weight of a hydrogenated acrylonitrile-butadiene copolymer rubber having a high hydrogenation rate, (2) 1 to 10 parts by weight of an organic peroxide, (3) 2,4-dimercapto- A rubber composition comprising 0.1 to 15 parts by weight of 6-substituted-1,3,5-triazine and (4) 1 to 100 parts by weight of an organic peroxide-crosslinkable epoxy group-containing polymer. |
