Problems solved by technology

[0002] With the development of automobile technology, automobiles are widely used in people's daily life. In the production of vehicles, in order to increase the comfort of vehicles, shock absorbers are used in the chassis system of automobiles for shock absorption and buffering. The bearing capacity of the lubricating oil used in the shock absorber is average. When the shock absorber works continuously, the lubricating oil cannot work well, causing damage to the piston rod, reducing the service life of the shock absorber, and there is still a problem with the shock absorption strength of the car. Not enough, the shock absorption and buffering process is not stable enough

Abstract

The invention discloses lubricating oil, with high bearing force, for an automobile absorber and relates to the technical field of automobile components. The lubricating oil, with high bearing force,for the automobile absorber is prepared from the following components in percentage by mass: 2.55-2.59 percent of camellia-seed oil-maleic anhydride copolymer and 0.012-0.014 percent of maleic anhydride modified nanometer diatomite. The lubricating oil, with high bearing force, for the automobile absorber is good in cooling performance and lubricating effect, can greatly improve the anti-rust property and the lubricating effect of the lubricating oil, is low in pour point, cannot be changed too much in friction coefficient at high temperature and is strong in stability, high in bearing abilityand low in cost.
