Problems solved by technology

At present, more than 95% of lubricating oils are mineral lubricating oils based on petroleum extracts, but petroleum is a non-renewable and scarce resource, and mineral lubricating oils cause great environmental pollution. Therefore, it is necessary to develop new base oils instead of mineral lubricating oils. Oil becomes a priority

Abstract

The invention discloses environment-friendly lubricating grease with high lubricating property. The environment-friendly lubricating grease is prepared from the following raw materials in parts by weight: 85 parts of base oil, 20 parts of 12-hydroxystearic acid, 8 parts of lithium hydroxide powder, 1 part of a complex heat stabilizer, 0.4 part of an auxiliary heat stabilizer, 0.5 part of carboxymethyl cellulose, 1 part of sodium dodecyl sulfate, 1 part of sodium dodecyl benzene sulfonate, 0.3 part of an antioxidant, 0.3 part of graphite and 0.3 part of glycerinum, wherein the base oil is prepared from epoxidized soybean oil and chlorinated paraffin in the mass ratio is 7:3 through mixing; the complex heat stabilizer is prepared from peanut oil and tea tree oil in the mass ratio is 2:1; theauxiliary heat stabilizer is prepared from calcium silicate, zinc oxide and aluminum oxide in the mass ratio is 3:2:2. The invention also provides a preparation method of the environment-friendly lubricating grease with the high lubricating property. The environment-friendly lubricating grease disclosed by the invention has very high lubricating property, is good in biodegradability and has smallpollution to environment.

Description

technical field [0001] The invention relates to a lubricating grease. More specifically, the invention relates to an environment-friendly lubricating grease with high lubricating performance, which belongs to the technical field of lubricants. Background technique [0002] Grease is a thick semi-solid, mainly composed of thickener, base oil, and additives. It is often used in the friction part of machinery to lubricate and seal, maintain the normal operation of various mechanical equipment, and reduce friction and wear. , Extend the service life of mechanical equipment, etc. At present, more than 95% of lubricating oils are mineral lubricating oils based on petroleum extracts, but petroleum is a non-renewable and scarce resource, and mineral lubricating oils cause great environmental pollution. Therefore, it is necessary to develop new base oils instead of mineral lubricating oils. Oil becomes a priority. Vegetable oil has good biodegradability, non-toxic and harmless, wi...
