Abstract

The invention relates to the technical field of rubber, in particular to a rubber used for preparing shock absorber top rubber. The rubber used to prepare the top rubber of the shock absorber is composed of the following raw materials in parts by weight: 70-90 parts of modified nitrile rubber, 25-40 parts of modified bamboo fiber, 5-12 parts of diatomite, Polyvinyl silicone oil 3~10 parts, epoxy resin 15~30 parts, clay 6~10 parts, rare earth 1~5 parts, sodium stearate 4~11 parts, calcium carbonate 6~13 parts, microcrystalline wax 2~ 9 parts, graphene 7~15 parts, gelatin 2~8 parts and antioxidant 1~7 parts. The rubber used for preparing the top rubber of the shock absorber has good oil resistance, heat resistance and abrasion resistance, low production cost and long service life.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber used for preparing shock absorber top rubber. Background technique [0002] At present, automobile shock absorbers, as an important shock absorbing element, have been widely used in various types of automobiles. When a car encounters potholes or stones during driving, the automobile shock absorber can effectively reduce, Absorbs vibrations transmitted by the road surface. The shock absorber top rubber can play the last shock absorption function when the car meets the road with a great impact on the shock absorber, so that there will be no head-to-head collision between the car bodies, which will cause damage to the car. It can improve the handling stability and safety of the car and reduce the noise of the car. Existing shock absorber top rubber is mostly made of rubber, and the wear resistance of the existing shock absorber top rubber decreases with the increase of tem...
