Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a graphene lubricating oil 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. With the increasingly intensified service conditions of various mechanical parts, the lubricating performance of lubricating oil is getting higher and higher. Lubricating oil is mainly composed of base oil and additives. Base oil mainly includes three categories: mineral base oil, synthetic base oil and biological base oil. In order to improve the lubricating performance of lubricating oil, various anti-wear additives are usually added to the base oil. At present, there are two main categories of an...
