Abstract

The invention relates to a novel automobile damper oil, which is composed of the following substances: a mixture composed of one or more components selected from: polymethacrylate, polyisobutene, and a carbon-chain strengthening agent; a mixture composed of one or more components selected from fatty alcohol polyoxyethylene ether, chlorinated paraffin, and phosphate; a mixture composed of one or more components selected from fatty alcohol ester of styrene-maleic anhydride resin, alkenyl butanediamide acid salt, sween, and tween; a mixture composed of one or more components selected from diisooctyldiphenylamine, 2,6-ditertbutyl-4-methypheonl, and phenothiazine; polyoxyethylene-polyoxypropylene segmented polyether, polyoxyethylene-polyoxypropylene glycerin, plant oil, and the balance being basic oil. The damper oil prepared according to the technical scheme mentioned above has improved performance indexes such as the viscosity index, and the like; and the work life of the damper oil is prolonged at the same time.

Description

technical field [0001] The invention relates to a kind of grease, in particular to a new type of shock absorber oil for automobiles. Background technique [0002] Cars have become a part of people's lives, and the ride comfort of cars has attracted people's attention no matter whether they are traveling or working. The shock absorber for cars is one of the important components that affect people's comfort. With the advancement of technology, hydraulic shock absorbers have been widely used. The hydraulic shock absorber generates damping force on the piston through its internal shock absorber oil to achieve the shock absorption effect, so the performance of the shock absorber oil directly affects the performance of the shock absorber. At present, the shock absorber oil has defects such as low viscosity, small damping, and short working life, which will lead to a decline in the working performance of the shock absorber. Contents of the invention [0003] The technical probl...
