Problems solved by technology

However, the anti-oxidation function of the existing lubricating grease is not ideal. While resisting oxidation, it cannot fully protect mechanical equipment
Because in the current grease production, human beings pay more attention to: the grease in the application of high load and high speed operation relies on strong hydrodynamic lubrication, and only anti-rust, anti-oxidation and anti-wear additives are paid attention to in the grease , so that the overall function of the grease has been affected to a certain extent

Abstract

The invention discloses an industrial lubricating grease antioxidant additive which is characterized by consisting of base oil, diarylamine, phenol ethoxylate, bis(salicylidene)propylene diamine, dialkldithiophosphate, antimony dialkldithiocarbamate, alklsuccinimide and polyisobutylene, wherein the weight percentages of the components are as follows: 42-46% of diarylamine, 3-5% of phenol ethoxylate, 3-5% of bis(salicylidene)propylene diamine, 4-6% of dialkldithiophosphate, 3-5% of antimony dialkldithiocarbamate, 3-4% of alklsuccinimide and 4-6% of polyisobutylene, and the balance of the base oil. The manufacturing method is simple, economical and practical with low cost, and can greatly improve the antioxidant capability of common lubricating grease; in addition, various performances of the lubricating grease are improved and the service life is prolonged when the antioxidant capability of the lubricating grease is improved. The invention does not hurt the mechanical devices and can improve various effects of the lubricating grease on all sides.

Description

(1) Technical field [0001] The invention relates to a lubricating grease additive, in particular to a preparation method and a preparation scheme of an industrial lubricating grease anti-oxidation additive. (two) background technology: [0002] Grease is currently used because of its specific semi-solid state, grease seals into bearings more easily than oil, and grease also acts as a seal against contamination in wet and dusty environments. Therefore, the use of lubricating grease is in great demand. The use of grease is very wide because of its wide range, so various types of grease additives are required to be used in grease. In order to meet people's requirements for the use of grease, the amount of grease additives used is larger than that of lubricating oil additives. However, the anti-oxidation function of the existing lubricating grease is not ideal, and the mechanical equipment cannot be fully protected while anti-oxidation. Because in the current grease productio...
