Self-lubricating rubber and preparation process thereof

Abstract

The invention discloses self-lubricating rubber and a preparation process thereof. The rubber provided by the invention is a novel product capable of continuously leaking a lubricant, can continuously play a self-lubricating role, reduces the technological process of secondary lubricating grease coating, saves the labor cost, the material cost and the equipment investment cost, and reduces the energy loss; the rubber continuously seeps out of the lubricating body, so that the influence of friction heat on rubber aging is reduced, lubrication of the contact surface of a connecting rod or a shaft or other moving parts and the rubber is improved, friction loss is reduced, and the service life of the oil seal can be prolonged; the problem of abnormal sound caused by friction between the oil seal and a connecting rod or a shaft is solved; compared with conventional rubber, the physical property of the rubber is obviously improved, the tensile strength and the rubber elongation are improved by 25% and 30% respectively compared with those of similar products, the constant value friction coefficient is reduced by 21.7%, the friction force between an oil seal and a connecting rod is reduced by 28%, and the Akron abrasion is reduced by 22.5%.

Description

technical field [0001] The invention relates to the field of automobile shock absorber accessories, in particular to a self-lubricating rubber and a preparation process thereof. Background technique [0002] As we all know, the friction between rubber and objects with a smooth surface is relatively large. In the field of shock absorbers, various companies are committed to the research and development of low-friction seals. Low friction will reduce frictional heat generation, and low thermal energy is conducive to increasing The service life of the shock absorber oil seal, high temperature will increase the internal pressure of the shock absorber, thereby increasing the oil seal's holding force on the connecting rod, the contact area will also increase, the heat generation will be more, and the shock absorber will enter a bad cycle. [0003] There are two main reasons for the failure of the oil seal in the prior art: 1. The frictional heat of the oil seal rubber causes the ru...

Problems solved by technology

2. The failure of the sealing part caused by the friction loss between the oil seal rubber and the moving parts

Less amount of application and insufficient lubrication are prone to greater abrasion of the lip of the oil seal, loss of luster on the surface, resulting in dry friction of the lip and accelerated wear of the oil seal
