Abstract

The invention relates to an antiwear agent used for lubricating oil, and a preparation method thereof, and belongs to the field of lubricating oil. The antiwear agent used for self-repairing lubricating oil is composed of, by mass, 30 to 70 parts of a lubricating oil base oil, 5 to 10 parts of h-BN nanosheet, 5 to 10 parts of nanometer graphene, 3 to 5 parts of aluminium hydroxide, 0.5 to 5 partsof boron oxide, 1 to 2 parts of dispersing agent 155, 1 to 2 parts of a fatty amine polyoxyethylene ether, and 1 to 5 parts of succimide. The antiwear agent used for lubricating oil is capable of prolonging the service life of lubricating oil, reducing wear loss of friction pairs, prolonging the service life of friction pairs, avoiding deposition of greasy filth and carbon formation effectively, and avoiding blocking.

Description

technical field [0001] The invention relates to an antiwear agent for lubricating oil and a preparation method thereof, belonging to the field of lubricating oil. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of 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 generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. [0003] Wear refers to the complex behavior phenomenon that the two relative moving surfaces of the friction pair are continuously lost or deformed during work. The use of lubrication technology ...
