Problems solved by technology

[0003] With the rapid development of the automobile industry, the demand for guide pins and spare parts of domestic automobile brake cylinders is also increasing. However, the technology of automobile brake accessories is still relatively backward, and the function of using grease is also relatively simple, so that the automobile brake The work brings great inconvenience, but also seriously affects the service life of the various parts of the car brake
Although imported lubricating grease can be used at present, its price is expensive, thus restricting the development of the automobile industry

Abstract

The present invention relates to the technical field of lubricating grease industry, especially to a vehicle brake branch pump guide pin lubricating grease and a preparation process thereof. The vehicle brake branch pump guide pin lubricating grease comprises, by weight, 50-70% of a base oil, 25-50% of a thickener, 0.5-3% of an antioxidant, 0.1-1% of an anti-corrosion agent, 1-5% of an extreme pressure anti-wear agent, and 0.3-1% of an anti-rust agent. The technical scheme of the present invention comprises the following steps: a, sequentially pouring base oil, antioxidant, an anti-corrosion agent, an extreme pressure anti-wear agent and an anti-rust agent into a reaction kettle to carry out stirring heating, and carrying out homogenization degassing to obtain the finished product. Compared with the vehicle brake branch pump guide pin lubricating grease in the prior art, the vehicle brake branch pump guide pin lubricating grease of the present invention has advantages of good water resistance, extremely low friction coefficient, effective noise reducing, good lubricity, good protection property, good thermal stability, high and low temperature property, colloidal stability, anti-oxidation, anti-corrosion stability and tightness.

Description

technical field [0001] The invention relates to the technical field of the lubricating grease industry, in particular to a lubricating grease for a guide pin of an automobile brake cylinder and a preparation process thereof. Background technique [0002] Grease English name: lubricating grease; grease thick grease like semi-solid. It is used for the friction part of the machine to lubricate and seal; it is also used on the metal surface to fill the gap and prevent rust; it is mainly prepared from mineral oil (or synthetic lubricating oil) and thickener. [0003] With the rapid development of the automobile industry, the demand for guide pins and spare parts of domestic automobile brake cylinders is also increasing. However, the technology of automobile brake accessories is still relatively backward, and the function of using grease is also relatively simple, so that the automobile brake The work of the car has brought great inconvenience, and has also seriously affected the...
