High-temperature-resistant rubber gasket for automobile shock absorbers

Abstract

The invention discloses a high-temperature-resistant rubber gasket for automobile shock absorbers, which is prepared from the following raw materials in parts by weight: 30-60 parts of cis-1,4-polybutadiene rubber, 15-35 parts of fluororubber, 10-20 parts of ethylene propylene diene monomer rubber, 20-40 parts of polyvinyl chloride resin, 2-6 parts of phenolic resin, 0.5-2.5 parts of sulfur, 0.5-1.5 parts of zinc diacrylate, 1-3 parts of zinc oxide, 0.5-2.5 parts of polyvinyl alcohol methyl ether, 2-6 parts of 1,3-polyethyleneglycol, 0.5-2.5 parts of N,N'-di(2-hydroxypropyl)aniline, 40-60 parts of modified silicon dioxide, 5-15 parts of dodecacarbonyltriiron, 1-5 parts of zinc ferrite, 5-12 parts of iron oxide red, 5-12 parts of nano silicon dioxide, 0.5-2.5 parts of isopropyl tri(dioctylpyrophosphate)titanate, 5-15 parts of talcum powder, 1-3 parts of zinc stearate, 0.5-2.5 parts of polyethylene wax and the like. The rubber gasket has excellent high-temperature resistance, shock absorptivity and tear resistance.

Description

technical field [0001] The invention relates to the technical field of rubber gaskets for shock absorbers, in particular to a rubber gasket for high-temperature-resistant automobile shock absorbers. 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.

[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
