Abstract

The invention discloses an engine lubricating oil anti-wear agent as well as a preparation method and application thereof. The engine lubricating oil antiwear agent comprises the following raw materials in parts by weight: 10-20 parts of polyimide, 25-35 parts of polyphenylparaben, 1-5 parts of nano-copper oxide, soluble polytetrafluoroethylene 3-6 parts of ethylene superfine powder, 1-20 parts of fluorocarbon surfactant, 10-15 parts of octadecyl borate polyoxyethylene ether, 3-10 parts of vinyl silicone oil, 4-20 parts of dimethyl silicone oil share. The engine lubricating oil antiwear agent of the present invention has reasonable compatibility, good compatibility with base oil, greatly enhances oil film strength, reduces friction coefficient and realizes self-repair; the preparation method of the antiwear agent is simple and low in cost, and is suitable for popularization and application .

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an anti-wear agent for engine lubricating oil and its preparation method and application. Background technique [0002] Lubricants are an integral part of machinery operation and maintenance. With the increasing load, speed, temperature and other working parameters of modern mechanical equipment, the original friction reducer and antiwear agent in lubricating oil can no longer fully meet the requirements of its antifriction and antiwear performance. In order to make up for the defects of liquid lubricating oil, the method of adding lubricating oil additives is usually used to improve the lubricating performance and anti-wear performance of lubricating oil, such as adding a variety of organic or inorganic mixtures, liquid or solid additives, which can pass physical or chemical adsorption or The chemical reaction forms a layer of liquid film, which improves the carrying ca...
