Abstract

The invention discloses a lubricant oil additive and relates to the technical field of fine chemical engineering. The lubricant oil additive is prepared from, by weight, 11-20 parts of hypophosphorous acid, 3-7 parts of potassium borate, 2-11 parts of para-diisooctyl diphenylamine, 5-8 parts of dimethyl silicone oil, and 1-5 parts of petroleum calcium sulfonate. The lubricant oil additive is prepared from the hypophosphorous acid, the potassium borate, the para-diisooctyl diphenylamine, the dimethyl silicone oil and the petroleum calcium sulfonate, so that the lubricant oil additive has high extreme pressure performance and anti-wear property, is good in compatibility with basic oil, can enhance stability and greatly improve viscosity index, guarantees long-acting effect of lubricant oil, is low in production cost, is convenient to use and improves effects and quality of the lubricant oil.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a lubricating oil additive. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is 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 for and improve the performance of base oil and endow some new properties. An important component of oil. [0003] The additives mainly include antioxidants, antiwear agents, friction modifiers, extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and anti-rust agents, flow point improvers, viscosity index improvers and other types according to thei...
