Problems solved by technology

[0002] In order to increase the anti-friction and anti-wear effect of lubricating oil, a small amount of lubricating oil additives are usually added to the lubricating oil. The traditional lubricating oil additives are sulfur, phosphorus or chlorine type anti-wear agents, which are corrosive to friction pair materials. Selectivity, especially lubricating oil additives containing elements such as sulfur, phosphorus or nitrogen, will emit exhaust gas and pollutants during use, thus causing pollution to the environment
[0003] Nano-additives help to improve the performance of lubricating oils, and graphene, a new carbon material formed by the close arrangement of single-layer carbon atoms, has a single-layer two-dimensional honeycomb lattice structure and is currently recognized as the thinnest in the world. Due to its special microstructure, graphene has excellent mechanical, thermal conductivity and electrical properties, but the existing technology uses N-methylpyrrolidine and petroleum ether to repeatedly wash to enhance the lipophilicity of graphene Although the method can improve the dispersion of graphene in lubricating oil, its process operation is complex and cumbersome, and it is accompanied by high pollutant emissions, which affects environmental protection
