Abstract

The invention relates to an automobile shock absorber oil suitable for low temperature environment. The automobile shock absorber oil is prepared from following materials: one or a mixture prepared from a plurality of compounds selected from polymethacrylate, poly(propylene-co-ethylene), and a carbon chain enhancer; one or a mixture prepared from a plurality of compounds selected from fatty alcohol-polyoxyethylene ether, chlorinated paraffin, and phosphorus pentoxide; one or a mixture prepared from a plurality of compounds selected from fatty alcohol ester of phenylethylene-maleic anhydride resin, alkenyl butanediamide acid salt, span, and tween; polyoxyethylene polyoxypropylene polyether, polyoxypropylene-polyoxyethylene glycerin, plant oil, and the balance base oil. The automobile shock absorber oil is capable of maintaining stability at low temperature, so that better working performance is obtained.

Description

technical field [0001] The invention relates to a kind of grease, in particular to a kind of automobile shock absorber oil suitable for low temperature environment. 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. But because the liquid is easy to solidify in low temperature environment, ordinary shock absorber oil will cause the shock absorber to be unusable due to its solidification in low temperature environment, affecti...
