Problems solved by technology

Automobile engines have the characteristics of high-frequency vibration and high heat generation. Therefore, the shock absorbers on automobile engines need to have high elasticity and high temperature resistance. However, the rubber used for shock absorbers on automobile engines is mostly ordinary shock-absorbing rubber. Its elasticity and high temperature resistance cannot meet the requirements, resulting in the aging of rubber ring sleeves, short service life and poor quality and reliability

Abstract

The invention discloses a rubber damper for automobiles. The rubber damper comprises raw materials in parts by weight as follows: 40-60 parts of nitrile rubber, 20-50 parts of natural rubber, 1-3 parts of zinc oxide, 1-3 parts of sulfur, 1.2-3 parts of an accelerant TE, 1-1.8 parts of tetramethyl thiuram disulfide, 0.5-1.5 parts of N-cyclohexyl-2-benzothiazole sulfonamide, 20-30 parts of light calcium carbonate, 20-40 parts of white carbon black, 40-60 parts of modified calcium sulfate, 1-2 parts of microcrystalline wax, 1-2 parts of dioctyl adipate, 2-7 parts of dioctyl terephthalate, 0.5-2.5 parts of stearic acid, 0.5-2.5 parts of an anti-aging agent 4020 and 1.5-2.3 parts of an anti-aging agent RD. The product is light in mass and good in elasticity and has excellent high-temperature-resistant performance and good anti-shocking performance.

Description

Technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber shock absorber for automobiles. Background technique [0002] As an important type of shock-absorbing components, rubber shock-absorbing parts have been widely used in automobiles, railway locomotives, water vehicles, airplanes, and so on. Among them, rubber shock absorbers are needed in all places where shock absorption and isolation are needed in automobiles. Automobile engines have the characteristics of high frequency vibration and high heat generation. Therefore, the shock absorbers on automobile engines need to have high elasticity and high temperature resistance. However, the rubber used in shock absorbers on automobile engines is mostly ordinary shock absorber rubber. Its elasticity and high temperature resistance cannot meet the requirements, which makes the rubber ring sleeve easy to age, short service life, and poor quality reliability. Summary of the in...
