Abstract

The invention discloses an engine lubricating oil anti-wear agent as well as a preparation method and application thereof. The engine lubricating oil anti-wear agent is prepared from the following rawmaterials in parts by weight: 10-20 parts of polyimide, 25-35 parts of poly-p-hydroxy phenyl benzoate, 1-5 parts of nano copper oxide, 3-6 parts of soluble polytetrafluoroethylene superfine powder, 1-20 parts of fluorocarbon surfactant, 10-15 parts of octadecaborate polyoxyethylene ether, 3-10 parts of vinyl silicone oil and 4-20 parts of dimethyl silicone oil. The engine lubricating oil anti-wear agent is reasonable in compatibility, is good in intermiscibility with base oil, greatly improves oil film strength, reduces a friction coefficient and realizes self-repair; and the preparation method for the ant-wear agent is simple, is low in cost, and is suitable for being popularized and applied.

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...
