Problems solved by technology

However, the processing and use performance of nanomaterials represented by graphene are significantly reduced due to agglomeration and other reasons during use, which severely limits the application of graphene.
Although there have been many research reports on the introduction of functional groups such as carboxyl, carbonyl, and long-chain fatty acids on the surface of graphene, the dispersion of graphene has been improved, but the problem of agglomeration of graphene still exists, making the lubricity of wear-reducing and anti-wear Performance is not improved

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a high thermal conductivity lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in 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 is composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil and endow some new properties. An important component of oil. [0003] The addition of nanomaterials (such as carbon nanotubes, graphene, fullerene, and graphite nanosheets) to lubricants can improve the tribological properties of lubricants. This is a rapidly developing emerging field....
