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

The damper comprises raw materials in parts by weight as follows: 25-60 parts of chloroprene rubber, 40-70 parts of natural rubber, 0.5-1.5 parts of zinc oxide, 1.5-2.5 parts of sulphur, 0.5-1.2 parts of an accelerant M, 1.5-3 parts of tetramethyl thiuram disulfide, 1-3 parts of an accelerant H, 30-50 parts of carbon black I, 15-25 parts of carbon black II, 20-40 parts of modified calcium sulfate, 1-3 parts of microcrystalline paraffin, 1-3 parts of microcrystalline wax OK1987, 1-3 parts of diisooctyl phthalate, 1-3 parts of stearic acid, 1-3 parts of an anti-aging agent AW and 1-3 parts of an anti-aging agent A. The product is light in mass, good in elasticity, very excellent in high-temperature resistance and very good in shock resistance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a shock-resistant and high-temperature-resistant rubber shock-absorbing part for automobiles. Background technique [0002] As a kind of important shock-absorbing components, rubber shock absorbers have been widely used in automobiles, railway locomotives, water vehicles and aircrafts, etc. Among them, wherever shock absorption and shock isolation are required in automobiles, rubber shock absorbers are required. 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, most of the rubber used for shock absorbers on automobile engines is ordinary shock-absorbing rubber. Its elasticity and high temperature resistance cannot meet the requirements, resulting in the aging of the rubber ring sleeve, short service l...
