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 an environment-friendly lubricating grease with high lubricating performance, comprising 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, and 1 part of composite heat stabilizer , 0.4 part of 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 antioxidant, 0.3 part of graphite and 0.3 part of glycerin; Among them, the base oil is made by mixing epoxidized soybean oil and chlorinated paraffin with a mass ratio of 7:3, the composite heat stabilizer includes peanut oil and tea tree oil with a mass ratio of 2:1, and the auxiliary heat stabilizer includes a mass ratio of 3 :2:2 calcium silicate, zinc oxide and aluminum oxide. At the same time, a preparation method of an environment-friendly lubricating grease with high lubricating performance is provided. The lubricity provided by the invention has high lubricating performance, good biodegradability and little environmental pollution.

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...
