High-temperature-resistant bearing lubricant additive

Abstract

The invention discloses a high-temperature-resistant bearing lubricant additive. The high-temperature-resistant bearing lubricant additive is prepared from, by weight, 6-12 parts of sodium dodecyl benzene sulfonate, 4-8 parts of fatty alcohol polyoxyethylene ether carboxylate, 5-9 parts of triphenyl phosphorothioate, 3-9 parts of zinc dialkyl dithiophosphate, 4-6 parts of para aminobenzoic acid, 6-9 parts of octyl phenol, 3-5 parts of calcium alkyl salicylate, 2-3 parts of a fluorinated surfactant, 2-5 parts of a fluorinated surfactant, 2-4 parts of cinnamyl alcohol, 5-12 parts of diisocyanate, 8-15 parts of dodecencylsuccinic acid, 3-6 parts of inositol hexaphosphoric acid, 4-8 parts of modified aluminium triphosphate, 4-8 parts of a viscosity index improver, 4-8 parts of an oxidation and corrosion inhibitor and 4-8 parts of an extreme pressure antiwear agent. Compared with the prior art, the lubricant additive has the advantages that the additive properties can be optimized through the compounding effect of multiple auxiliaries, the good lubricant property enhancing effect can be achieved through a little amount of the additive, the high temperature resistance, the viscosity property and the wear resistance of a lubricant can be promoted, and the quality of the lubricant is greatly promoted.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a high temperature resistant bearing lubricating oil additive. Background technique [0002] The concept of lubricating oil additives is to add one or several compounds in the lubricant to make the lubricant obtain some new characteristics or improve some existing characteristics of the lubricant. According to the function, the additives mainly include antioxidants, antiwear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and anti-rust agents, flow point improvers, and viscosity index enhancers. types of agents. The additives sold in the market are generally compound products of the above single additives. The only difference is the composition of the single additive and the ratio of several single additives in the compound additive. However, the synergistic effect after the add...
