摘要（英）：

The invention discloses a wear-resisting anti-ageing damping rubber material which comprises the following components in parts by weight: 30-40 parts of cis-polybutadiene, 15-25 parts of nitrile rubber, 20-35 parts of polyethylene, 12-18 parts of carbon black, 8-15 parts of ultrafine coal ash, 1-3 parts of a vulcanizing agent, 2-5 parts of an accelerant, 3-5 parts of calcium stearate, 3-5 parts of barium stearate, 1-3 parts of chlorcosane-42, 3-5 parts of nanometer silicon dioxide, 1.5-3 parts of vaseline, 4-5 parts of nanometer zinc oxide, 1-2 parts of an antioxidant, 1-2 parts of an anti-ageing agent, 2-4 parts of a silane coupling agent, 2-4 parts of a cross-linking agent, 2-4 parts of a compatilizer and 1-2 parts of sulfur powder. The cis-polybutadiene, nitrile rubber and polyethylene are compounded with each other, so that the tensile strength and stress at definite elongation of the products can be promoted, the heat generation and the compression deformation can be reduced, and the product has excellent wear resistance, cold resistance, warping strength, ageing resistance, oil resistance, toughness and tensile strength.
