The damping rubber part comprises raw materials in parts by weight as follows: 40-50 parts of butadiene rubber, 15-35 parts of chloroprene rubber, 5-15 parts of modified rosin, 0.5-1.5 parts of zinc oxide, 1-2 parts of sulfur, 1-3 parts of a vulcanization accelerator ZBX, 1-3 parts of a vulcanization accelerator CZ, 1-3 parts of N-cyclohexyl-2-benzothiazole sulfonamide, 40-60 parts of white carbon black, 5-15 parts of titanium dioxide, 20-35 parts of calcium sulfate, 5-15 parts of diatomite, 1-3 parts of coumarone, 1-3 parts of a plasticizer DOP, 1-3 parts of stearic acid, 1-3 parts of N-phenyl-alpha-aniline and 1-3 parts of N-phenyl-beta-naphthylamine. The product has good mechanical performance, high elasticity and excellent anti-aging performance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a shock-absorbing rubber part for an automobile bushing. Background technique [0002] With the increase of vehicle speed, the dynamic effect on the line increases sharply, causing severe wear and tear on the line, tires and components of the locomotive running part, and the requirements for shock resistance of various parts of the car are getting higher and higher. Therefore, it is necessary to take necessary measures to eliminate the impact of vibration. Rubber is characterized by both high elastic state and high viscous state, which makes it unparalleled in buffering, shock absorption and dynamic sealing. Rubber parts are widely used to isolate vibration and absorb shock. The shock-absorbing rubber products used for automobile bushings are required to have good mechanical properties, high elasticity, and excellent aging resistance, but the shock-absorbing rubbers use...
