Rubber gasket used for automobile shock absorber and having excellent mechanical property

Abstract

The invention discloses a rubber gasket used for an automobile shock absorber and having excellent mechanical property, prepared from the following raw materials in parts by weight: 35-45 parts of butadiene rubber, 12-24 parts of natural rubber, 13-28 parts of XNBR, 5-16 parts of chlorosulfonated polyethylene rubber, 2-8 parts of phenolic resin, 1.2-1.8 parts of sulphur, 0.5-1.5 parts of DPTT, 1.5-2.5 parts of zinc oxide, 0.2-0.9 part of polyvinyl methyl ether, 1-4 parts of 1,3-polyethylene glycol, 0.5-2.2 parts of N,N minute-Bis(2-hydroxypropyl)aniline, 35-55 parts of modified silicon dioxide, 5-10 parts of triiron dodecacarbonyl, 2-6 parts of zinc ferrite, 5-10 parts of iron oxide red, 6-12 parts of acetylene black, 2-8 parts of tetraisopropyl di(dilauryl phosphite) titanate, 2-10 parts of light calcium carbonate and the like. The rubber gasket is super in high temperature resistance, shock absorption property and tear resistance, and excellent in mechanical property.

Description

technical field [0001] The invention relates to the technical field of rubber gaskets for shock absorbers, in particular to a rubber gasket for automobile shock absorbers with excellent mechanical properties. Background technique [0002] During the driving process of the vehicle, the vibration of the car is aroused by many factors due to the unevenness of the road surface. The shock and vibration caused by the unevenness of the road are transmitted to the suspension through the wheels, and then transmitted to the body by the suspension. As a result, the vibration of the driver and its passengers is caused, and of course it also forms an impact on the cargo. This vibration greatly reduces the stability of the vehicle, and the vibration affects people's comfort, work efficiency and health. With the improvement of people's living standards, the performance of rubber gaskets for shock absorbers in the vehicle is becoming more and more critical. Traditional rubber gaskets for sh...

[0002] During the driving process of the vehicle, the vibration of the car is aroused by many factors due to the unevenness of the road surface. The shock and vibration caused by the unevenness of the road are transmitted to the suspension through the wheels, and then transmitted to the body by the suspension. As a result, the vibration of the driver and its passengers is caused, and of course it also forms an impact on the cargo. This vibration greatly reduces the stability of the vehicle, and the vibration affects people's comfort, work efficiency and health.

With the improvement of people's living standards, the performance of rubber gaskets for shock absorbers in the vehicle is becoming more and more critical. Traditional rubber gaskets for shock absorbers are prone to vibration and fatigue, and have poor shock absorption performance and are not durable. High temperature, poor mechanical properties
