Abstract

The invention provides environment-friendly shock absorber oil for automobiles. The environment-friendly shock absorber oil is prepared from components in mass percent concentration as follows: 56.5%-65% of epoxidized rapeseed oil, 26.5%-35% of synthetic hydrocarbon, 3%-4% of a pour point depressant, 0.5%-1.5% of an extreme pressure additive and 0-3% of an antioxidant. The invention further provides a preparation method of the shock absorber oil. The oxidation resistance, the lubricity and the shear stability of the shock absorber oil are greatly superior to those of domestic same-type mineral oil type shock absorber oil, the low-temperature fluidity of the shock absorber oil can be improved obviously by means of addition of the synthetic hydrocarbon and the pour point depressant, and the shock absorber oil is all-weather environment-friendly shock absorber oil with high lubricity.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to organic chemistry, in particular to an environment-friendly automobile shock absorber oil and a preparation method thereof. Background technique [0002] The shock absorber is an important part of the car body. The shock absorber is 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. It can be seen that although the shock absorber can effectively reduce the vibration caused by the uneven road surface and the vibration caused by the rebound of the shock absorbing spring, it can make the car run more smoothly. However, the working environment of the shock absorber itself is relatively harsh, and it is rela...
