Description

technical field

[0001] The invention belongs to the field of macromolecule and its application, in particular to a modified graphene lubricating oil with high dispersibility and affinity, and also relates to a preparation method of the modified graphene lubricating oil. Background technique

[0002] Friction and wear are ubiquitous in nature, causing more than 50% of the world's primary energy loss due to friction and wear, and wear is one of the main reasons for the scrapping of materials and equipment. In order to reduce friction and wear, people add lubricating oil between workpieces, but the economic loss of tens of billions of yuan is still caused to the country every year due to friction and wear. Therefore, reducing friction, reducing wear, reducing wear, and prolonging the life of parts are the goals that researchers in tribology, chemistry and materials are constantly pursuing. In order to improve the lubricating performance of lubricating oil, various anti-wear ad...
