A kind of preparation method of environment-friendly type automobile lubricating grease

Abstract

The invention discloses environment-friendly type grease and a preparation method thereof. The grease is prepared from plant-based synthetic oil, sodium-based bentonite, Sasol wax, chlorinated paraffin, a detergent and dispersant, an emulsifier, an extreme pressure agent, an anti-oxidant, an agent for preventing corrosion and rust, organic acid, calcium hydrate, and water. Settlement of the grease is not easy and lubrication performance is good, the grease can effectively reduce friction and reduce loss, the preparation method is simple, and production cost is low; the maximum non-seizure load of the grease is greatly improved, the grease has the advantages of excellent conventional physical and chemical performances, ecological characteristics that cannot be matched by common grease, good lubricity and stability, and high degradation rate; and the grease accords with environmental protection requirements.

Description

technical field

[0001] The invention relates to a lubricating grease for vehicles and its preparation, in particular to an environment-friendly lubricating grease for vehicles and a preparation method thereof. Background technique

[0002] Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oils are widely used and used in a large amount (about 95%), but in some applications, products formulated with synthetic base oils and bio-oil base oils must be used, thus making these two base oils develop rapidly.

[0003] The most popular lubricating products in the Chinese market are mostly petroleum-based lubricating oils, which are difficult to degrade and remain in the environment for almost a long time. The annual global consumption of lubricating products is 36-40 million tons, of which about 10 million tons of lubricating products directly enter the ecological environment where humans live ...
