Abstract

The invention discloses shock absorber oil applicable to a low-temperature environment. The shock absorber oil comprises, by weight, 90-100 parts of ethylhydrosilicone fluid, 5-10 parts of alkenyl half-ester succinate, 40-50 parts of HVIW H60 base oil, 5-8 parts of sodium stearyl fumarate, 3-5 parts of triazoloammonium salt, 4.5-6 parts of nanometer titania, 3-5 parts of a cross-linking agent, 2-3 parts of a rust-inhibiting additive, 1-1.5 parts of phenothiazine, 5-10 parts of castor oil, 2.5-3 parts of imidazolidinyl urea, 1-2 parts of hydrobromide, 3-5 parts of a viscosity index improver and 3-5 parts of octamethylcyclotetrasiloxane. Through the above mode, the shock absorber oil has good usability and is especially applicable to a low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to shock absorber oil suitable for low-temperature environments. Background technique [0002] Shock absorbers are used in automobiles, motorcycles, and bicycles. Shock absorbers are mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. Shock absorber is too soft, automobile body can hop up and down, shock absorber can bring too great resistance too forcedly, cloggy bedspring works normally. [0003] The performance of the shock absorber oil has a direct impact on the performance of the shock absorber. The existing shock absorber oil is not suitable for use in low temperature environments and needs to...
