Abstract

The present invention discloses an automobile control arm bushing rubber material and a preparation method, the rubber material is mainly made from the following components by weight: 40 parts of polyethylene terephthalate, 30-50 parts of chlorosulfonated polyethylene, 40 to 60 parts of natural rubber, 1-9 parts of ethyl benzoate, 2-6 parts of glyceryl stearate citrate, 1-5 parts of zinc oxide, 2-8 parts of carbon black, 0.2 to 0.6 part of an antioxidant, 0.1 to 0.7 part of an accelerator, 0.5 to 1.5 parts of sulfur and 10 to 20 parts of paraffin oil. Compared with the prior art, the automobile control arm bushing rubber material obtained by the preparation method is simple in process and low in cost, not only has the heat and wear resistance and other properties of automobile control arm bushings of the prior art, and to be most important, the automobile control arm bushing rubber material combines hardness and fatigue resistance and excellent overall performance.

Description

technical field [0001] The invention relates to a rubber material for an automobile control arm bush and a preparation method thereof, belonging to the technical field of rubber materials. Background technique [0002] Automobile control arm bushing, as an important part connecting the wheel and the control arm, plays a decisive role in controlling the vehicle's steering balance control, acceleration and deceleration attitude suppression. With the rapid development of China's economy, family cars have gradually entered ordinary families, and people have higher and higher requirements for the safety and handling of cars. The car control arm is an important connecting part of the car and an important part of the car steering system. One of the rubber materials, it plays an important role in the driving safety and handling performance of the car. Since this product bears a high load for a long time, and withstands several times the load increase in an instant under the conditi...
