High-elasticity durable automobile rubber shock absorbing material

Abstract

The invention discloses a high-elasticity durable automobile rubber shock absorbing material. The high-elasticity durable automobile rubber shock absorbing material comprises a shock absorbing material body and a wear-resistant coating which coats the outer side of the shock absorbing material body; the shock absorbing material body is prepared from the following raw materials in parts by weight:20 to 30 parts of EPDM, 20 to 25 parts of butyl rubber, 10 to 15 parts of butadiene rubber, 4 to 7 parts of talcum powder, 2 to 5 parts of a toughening agent, 2 to 4 parts of an antioxidant, 1 to 4 parts of an anti-aging agent, 1 to 3 parts of a coupling agent, 3 to 9 parts of epoxidized soybean oil, 3 to 6 parts of a maleic anhydride compatilizer, 3 to 7 parts of paraffin, 5 to 8 parts of nano-barium sulphate, 2 to 5 parts of modified nano silicon nitride, 1 to 3 parts of potassium stearate, 2 to 5 parts of an accelerant, 2 to 4 parts of a coupling agent, 1 to 2 parts of zinc borate and 3 to7 parts of sulphur. According to the high-elasticity durable automobile rubber shock absorbing material, the wear resistance and the durability of a shock absorbing piece are greatly improved by the wear-resistant coating on the outer side of the shock absorbing material body.

Description

technical field [0001] The invention relates to the field of automobile processing, in particular to a high-elastic and durable automobile rubber shock absorber material. Background technique [0002] With the rapid development of modern industry, vibration and noise have become serious problems in various fields. It will reduce the operating accuracy, affect product quality, shorten product life, make high-precision instruments not work normally, and endanger safety. [0003] In the processing and manufacturing of automobiles, the shock absorber is one of the essential parts. It is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface, which plays a role in the comfort and handling stability of the vehicle. important role. The principle of the existing shock absorber bushing is to convert the mechanical energy of vibration into thermal energy through the elastic support and dissipate it to the surrounding ...

AI Technical Summary

Problems solved by technology

The metal and rubber shock-absorbing bushing has certain performance requirements for rubber, and there is still a lot of room for improvement in the performance of existing rubber products in terms of wear resistance, aging resistance, and elasticity.
