Abstract

The invention belongs to the field of chemical industry, and relates to a thiadiazole-derivative / graphene-containing lubricating oil additive and a preparation method thereof, and a lubricating oil containing the additive. The additive comprises thiadiazole derivatives, graphene, mercaptan, isopropanol, a 30 wt% formaldehyde solution, rare earth chlorides, alkali liquor and phenol substitutes. The nano graphene, which is used as the lubricating oil additive into the lubricating oil, has the functions of protection and repair, and forms a protective film, which can not be penetrated through even by hydrogen atoms, on the inner wall surface of the machine. When the graphene starts to be abraded, the hydrogen atoms jump and repair the crystal lattices, which indicates that the nano-graphene-added lubricating oil can keep permanently effective. The functional groups of the thiadiazole derivatives can form coordinate bonds and hydrogen bonds with graphene, thereby being beneficial to enhancing the dispersity of the graphene in the lubricating oil and the adsorption strength of the lubricating oil and graphene on the metal surface.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a lubricating oil additive containing thiadiazole derivatives and graphene, a preparation method of the additive, and a lubricating oil containing the additive. Background technique [0002] Energy and the environment are two major themes of sustainable economic and social development. For mechanical parts, friction and wear are unavoidable. The friction and wear of mechanical parts will not only cause a large loss of materials and energy, but also cause very serious environmental pollution. Adding tribological additives to lubricating oil is one of the important technical means to effectively slow down the friction and wear of mechanical parts and reduce energy loss. In recent years, the preparation and application technology of nano-metal materials has made great progress, and has gradually reached the level of industrialization. Nano metal particle material refers to metal ul...
