Abstract

The invention discloses a shock absorber oil seal with good rebound resilience, which comprises the following raw materials in parts by weight: 100 to 104 parts of fluorous rubber F26, 3 to 5 parts of wannianhui, 2 to 3 parts of polyethylene glycol 1000, 1 to 2 parts of dithiosalicylic acid, 3 to 4 parts of propolis, 10 to 14 parts of fumed silica, 2 to 3 parts of 1-stearoyl-rac-glycerol, 6 to 8 parts of SG-3 type PVC (polyvinyl chloride) resin, 1 to 2 parts of absolute ethyl alcohol, 6 to 8 parts of cresyl diphenyl phosphate, 1 to 2 parts of imethylaminopropylamine, 1 to 2 parts of magnesium chloride, 1 to 2 parts of di-tert-butyl peroxide, 0.3 to 0.5 parts of sulphur, 1 to 2 parts of an accelerant CZ, 1 to 2 parts of an antiager 4010, and 18 to 26 parts of composite fillers. The shock absorber oil seal has the advantages that the original shape of the oil seal is kept, the tracking performance is excellent, the sealing effect is good, the mechanical property is good, the weather resistance is good, and the service life is long.

Description

technical field [0001] The invention mainly relates to the field of auto parts, in particular to a shock absorber oil seal with good resilience. Background technique [0002] Fluorine rubber is resistant to aging, heat, and oil, and is suitable for almost all lubricating oils, fuel oils, gasoline, and is not easy to harden in oils containing extreme pressure additives, but has poor cold resistance, high temperature wear resistance, and large permanent compression deformation , suitable for temperature -20 ~ 250 ℃. It is mainly used for high temperature resistant oil seals such as engine oil seals, so adding additives to improve the comprehensive performance of fluororubber can increase the scope of use of fluororubber. Contents of the invention [0003] The object of the present invention is to provide a shock absorber oil seal with good resilience. [0004] The present invention is achieved through the following technical solutions: [0005] A shock absorber oil seal w...
