Description

technical field [0001] The invention belongs to the technical field of automobile processing and manufacturing, and in particular relates to a preparation method of a heat-resistant and anti-aging 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 en...
