Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a nano-synthetic lubricating oil and a preparation method thereof. Background technique [0002] Materials are the material basis for human survival and development, the core of all scientific and technological progress, the forerunner of high-tech development and social modernization, and the reflection and symbol of a country's scientific, technological and industrial level. During the use of the material, due to the friction between the surface of the material and the interface, a large amount of mechanical energy will be lost, which may easily cause the wear of mechanical parts. Therefore, it is necessary to regularly add and replace the lubricating oil during the operation of the machine. Lubricating oil is a liquid or semi-solid lubricating oil used on mechanical parts to reduce friction and protect machinery and processing parts, mainly for lubrication, auxiliary c...
