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 antirust and anticorrosion additive for lubricating grease, consisting of base oil; sodium sebacate; phenothiazine; disalicylidene propylenediamine; dialkyl dithiophosphate; lead naphthenate; calcium carbonate; ; Composition of random polypropylene. The base oil is a combination of two components of 150BS and M14 of mineral oil and one component of soybean 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 29%; sodium sebacate 48%; phenothiazine 3%; disalicylidene propylenediamine 3%; dialkyl dithiophosphate 5%; 3% lead acid; 2% calcium carbonate; 5% polyisobutylene; 2% random polypropylene. The above base oil; sodium sebacate; phenothiazine; disalicylidene propylenediamine; dialkyl dithiophosphate; lead naphthenate; calcium carbonate; Components should be measured by weight percentage. Mix evenly, heat and control the temperature between 55-60°C, and stir for 120 minutes to obtain the pro...

Abstract

The invention discloses a lubricating grease antirust anticorrosive additive, which is basically characterized by comprising the following components in percentage by weight: 48 to 53 percent of sodium hydrogen sebacate, 3 to 5 percent of phenothiazine, 3 to 5 percent of bis(salicylidene)-propanediamine, 5 to 7 percent of dialkyl two glucosinolate and phosphate, 3 to 6 percent of lead naphthenate, 2 to 5 percent of calcium carbonate, 5 to 8 percent of polyisobutene, 2 to 4 percent of atactic polypropylene, and the balance of base oil. The preparation method is simple; the preparation scheme is economic and practical; the cost is low; the additive can greatly improve the antirust and anticorrosive functions of common lubricating grease, improve the antirust and antioxidation performance of the lubricating grease and various comprehensive properties of the lubricating grease and prolong the service life of the lubricating grease, and has good protection effect on mechanical equipment.

Description

(1) Technical field [0001] The invention relates to a lubricating grease antirust and anticorrosion additive, in particular to a preparation method and a preparation scheme of the lubricating grease antirust and anticorrosion additive. (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 i...
