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] An anti-rust additive for industrial greases, consisting of base oil; ethoxylated phenols; diarylamine; bis-salicylidene propylene diamine; dialkyl dithiophosphate; antimony dialkyl dithiocarbamate ; Calcium carbonate; Polyisobutylene; Polyethylene composition. The base oil is a combination of three components of 150BS and 32# of mineral oil and rapeseed oil in vegetable oil. The weight ratio of the three components is 1:1:1. The weight percentages of each component are: base oil 28%; ethoxylated phenols 50%; diarylamine 3%; bis-salicylidene propylene diamine 3%; dialkyl dithiophosphate 6%; Antimony alkyl dithiocarbamate 3%; calcium carbonate 2%; polyisobutylene 3%; polyethylene 2%. The above-mentioned base oil; ethoxyphenols; diarylamine; bis-salicylidene propylene diamine; dialkyl dithiophosphate; antimony dialkyl dithiocarbamate; calcium carbonate; polyisobutylene; Ethylene: Measured by weight percentage of each component. Mix uniformly, heat and control the temper...

Abstract

The invention discloses an industrial lubricating grease antirust additive, which is basically characterized by consisting of the following components in percentage by weight: 50 to 54 percent of ethoxy phenol, 3 to 5 percent of diaryl amine, 3 to 5 percent of disalicylidene propylene diamine, 6 to 7 percent of dialkyl dithiophosphate, 3 to 5 percent of dialkyl antimony dithiocarbamate, 2 to 3 percent of calcium carbonate, 3 to 4 percent of polyisobutene, 2 to 3 percent of polyethylene and the balance of base oil. The additive is easy to prepare, the preparation scheme is economic and practical and has low cost, and the additive can greatly promote the antirust and anticorrosion functions of the common lubricating grease; and the additive improves various comprehensive properties of the lubricating grease while promoting the antirust and anti-oxidation properties of the lubricating grease, can prolong the service life of the lubricating grease, and can well protect multiple kinds of mechanical equipment.

Description

(1) Technical field [0001] The invention relates to an antirust additive for industrial lubricating grease, in particular to a preparation method and preparation scheme of an antirust additive for industrial lubricating grease. (2) Background technology: [0002] The current use of grease is because of the semi-solid state of the grease, the grease is easier to seal into the bearing, and the grease can also act as a seal to resist pollution in a humid and dusty environment. Therefore, the use of grease is in great demand. Moreover, the application range of grease is also very wide, so various grease additives are required to improve the working performance of various greases, so as to meet the requirements of people for the use of grease, so the current additives used for grease are better than The amount of lubricant additives used is still large. However, the existing anti-corrosion and anti-corrosion functional additives for lubricating greases are not ideal, and while preve...
