Abstract

The invention provides a high-abrasion-resistance lubricating oil containing carbon nitride-graphene additive and a preparation method thereof. A two-dimensional carbon-nitride nano-sheet is dispersedin excess copper chloride and graphene colloid solution, copper chloride is reduced to copper in hydrogen gas environment, and graphene is fixed on the surface of the two-dimensional carbon-nitride;the product is subjected to further treatment in a reactor under inert gas protection 5-10 seconds, copper on the surface of carbon-nitride is micro-melted by instantaneous high temperature, and the abrasion-resistance composite additive of the carbon-nitride loaded with graphene is prepared; the high-abrasion-resistance lubricating oil containing two-dimensional carbon nitride-graphene additive is synthesized by mixing the abrasion-resistance composite additive with base oil and various auxiliaries. The two-dimensional carbon nitride-graphene additive is prepared, the conventional additive carbon nitride is used as carrier, so as to significantly improve the dispersion of graphene in base oil, improve the stability of lubricating oil, and effectively improve the friction and wear behaviorof friction surface in application, and furthermore be conducive to prolonging the service life of mechanical parts.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to the preparation of high wear-resistant lubricating oil, in particular to a high wear-resistant lubricating oil containing carbon nitride-graphene additive and a preparation method thereof. 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, auxiliary 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] Lubricating oil additives are a key part of lubricating ...
