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 comprehensive 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 strong hydrodynamic lubrication, and The current grease production 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.

Embodiment 1

[0010] A grease rust inhibitor, consisting of base oil; fatty amine; oligomer of trimethylhydroquinazole; disalicylidene propylenediamine; phosphoric acid ester; dialkyl antimony dithiophosphate; calcium acetate; Polyisobutylene; composed of alkyl succinimide. The base oil is a combination of three components of mineral base oil 500SN and M14 and rapeseed oil in vegetable oil, and the weight ratio of the three components is 1:1:1. The weight percent of each component is: base oil 31%; Fatty amine 48%; Trimethylhydroquinazole oligomer 3%; Disalicylidene propylene diamine 3%; Phosphate ester 5%; Antimony dithiophosphate 3%; Calcium acetate 2%; Polyisobutylene 3%; Alkyl succinimide 2%. The above base oil; fatty amine; oligomer of trimethylhydroquinazole; disalicylidene propylenediamine; phosphoric acid ester; Imine; measured according to the percentage by weight of each component. Mix evenly, heat and control the temperature between 55-60°C, and stir for 120 minutes to obtain ...

Abstract

The invention discloses a lubricating grease rust oxidation, which is characterized by consisting of the following components in percentage by weight: 48 to 56 percent of fatty amine, 3 to 5 percent of oligomer of trimethyl hydroquinazol, 3 to 6 percent of bis(salicylidene)-propanediamine, 5 to 7 percent of phosphate, 3 to 5 percent of antimony dialkyl dithiophosphate, 2 to 4 percent of calcium acetate, 3 to 6 percent of polyisobutene, 2 to 4 percent of alkyl succinimide, and the balance of base oil. A preparation method is simple; the preparation scheme is economic and practical and low in cost; the rust resistance and corrosion resistance functions of the common lubricating grease can be improved greatly; various comprehensive properties of the lubricating grease can be improved while the rust resistance and oxidization resistance of the lubricating grease are improved; and the life cycle of the lubricating grease can be prolonged. The lubricating grease rust oxidation can play a good role in protecting multiple kinds of mechanical equipment.

Description

(1) Technical field [0001] The invention relates to a lubricating grease additive, in particular to a preparation method and a preparation scheme of a lubricating grease rust inhibitor. (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 cannot comprehensively impro...
