Abstract

The present invention relates to the technical field of lubricating grease industry, especially to a vehicle central controlled lock lubricating grease and a preparation process thereof. The vehicle central controlled lock lubricating grease comprises, by weight, 55-70% of a base oil, 0.3-1% of calcium hydroxide, 5-15% of benzoic acid, 8-15% of high purified water, 0.5-2% of boric acid, 3-8% of a lithium hydroxide oil mixture, 0.5-6% of an anti-rust agent, 0.5-2% of an anti-oxidation and anti-corrosion agent, and 0.1-4% of an extreme pressure anti-wear agent. The preparation method comprises: carrying out stirring-heating on high purified water, benzoic acid, base oil, calcium hydroxide, boric acid, a lithium hydroxide oil mixture, an anti-rust agent, an anti-oxidation and anti-corrosion agent and an extreme pressure anti-wear agent, and finally carrying out homogenization degassing to obtain the finished product. Compared with the vehicle central controlled lock lubricating grease in the prior art, the vehicle central controlled lock lubricating grease of the present invention has advantages of excellent shear resistance, excellent water resistance, extreme low friction coefficient, effective noise reducing, good oxidation resistance, and good corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of the lubricating grease industry, in particular to an automobile central lock lubricating grease and a preparation process thereof. Background technique [0002] In addition to lubricating with liquid lubricating oil, the friction points of automobile movement mechanisms also need to be lubricated with grease. Due to differences in vehicle models and different lubricating parts, the grease has extreme pressure, anti-wear, temperature resistance, and long life. Different performance requirements. [0003] With the rapid development of the automobile industry, the environment encountered in the use of automobiles is becoming more and more complex. At the same time, the transformation and development of automobiles put forward higher requirements for lubrication performance. For example, the central locking of automobiles has changed from the previous mechanical type to the direction of intelligence and huma...
