Problems solved by technology

However, the existing anti-corrosion and anti-corrosion functional additives for lubricating grease are not ideal enough, and it is impossible to fully improve the working performance of lubricating grease while anti-corrosion and anti-corrosion
It cannot provide all-round protection for mechanical equipment, because in the production process of various types of greases, human beings pay more attention to: greases in light load and high-speed operation applications rely on forced hydrodynamic lubrication, and now The production of lubricating grease only pays attention to anti-rust, anti-oxidation and anti-wear
Therefore, the overall effectiveness of the grease has been affected to a certain extent.

Abstract

The invention relates to a lubricating grease antirust additive used for lubricating grease. The additive is characterized by comprising, by weight: 50-53% of phosphate ester and amine salts; 2-3% of phenothiazine; 2-4% of bis(salicylidene) propylenediamine; 4-6% of a dialkyl dithiocarbamic acid metal salt; 2-5% of chlorinated paraffin; 2-3% of calcium phosphate; 7-8% of polyisobutylene, and the balance base oil. With simple preparation method, economical and practical preparation scheme, and low cost, the additive of the invention can substantially enhance the anticorrosion function of common lubricating grease, and improves various comprehensive performances of lubricating grease while raising the antirust and oxidation resisting performances of lubricating grease, as well as prolongs the service period of lubricating grease, thus playing a good protective role in various mechanical equipment.

Description

(1) Technical field [0001] The invention relates to a lubricating grease additive, in particular to a preparation scheme and a manufacturing method of a lubricating grease antirust additive for lubricating grease. (two) background technology: [0002] The current use of grease is that it is easier to seal into bearings due to the semi-solid state of the grease, and the grease also acts as a seal against contamination in wet and dusty environments. Therefore, the use of grease is in great demand. Moreover, the use range of grease is also very wide, so various types of grease additives are required to improve the working performance of various greases, so as to meet people's requirements for the use of grease, so the additives currently used for grease are more expensive than grease additives. The use of lubricating oil additives is also large. However, the existing anti-corrosion and anti-corrosion functional additives for lubricating greases are not ideal enough, and they ...
