Additive for improving anti-oxidation and anti-corrosion performance of lubricating oil

Abstract

The invention discloses an additive for improving the anti-oxidation and anti-corrosion performance of lubricating oil. The additive is prepared from methacrylic acid, tertiary butylhydroquinone, phytic acid, diethylamine, boric acid, propyl-octyl secondary-primary alkyl zinc dithiophosphate, double-octyl primary alkyl zinc dithiophosphate, sulfurized olefin, lupenyl palmitate, polysiloxane, camellia seed husk extract and a nano-particle mixture. All ingredients of the lubricating oil have a mutual effect and cooperate with one another, so that the anti-oxidation and anti-corrosion effects of the lubricating oil are significantly improved, and the stability, wear resistance, dispersity, lubricating property and the like of the lubricating oil are all well improved; the lubricating oil can be widely applied to lubricating of various mechanical equipment and significantly improve the anti-oxidation and anti-corrosion effects of the mechanical equipment, and has high market competitiveness.

Description

technical field [0001] The invention relates to a lubricating oil additive, in particular to an additive for improving the anti-oxidation and anticorrosion performance of lubricating oil. Background technique [0002] Friction and wear is a ubiquitous natural phenomenon, and lubricating oil is one of the most effective ways to reduce friction and resist wear. In-situ repair of worn surfaces during motion has always been the goal pursued by lubricators. Lubricating oil is generally composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up and improve some properties of base oil. Lubricating oil is divided into three categories according to its source: moving oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. The amount of petroleum lubricating oil accounts for more than 97% of the total amount, so lubricating oil often refers to petroleum lubric...

Problems solved by technology

[0003] At present, the common anti-oxidation additives for lubricating oils on the market are relatively single in composition, and some anti-oxidation and anti-corrosion components are usually added, but usually the function of the lubricating oil is not significantly improved, because the various properties of the lubricating oil are the result of the joint action of all components , and different ingredients will have an impact on different properties, and the effect of simply adding a certain functional ingredient is not obvious
