Description

technical field [0001] The invention belongs to the technical field of chemical additives, in particular to a thiadiazole derivative modified graphene and its preparation method and application. Background technique [0002] In order to improve the lubricating performance of grease and prolong the service life of equipment, a certain amount of extreme pressure antiwear agent needs to be added to it to form a protective film (adsorption or reaction film) on the friction surface, thereby preventing direct contact between metals and reducing the friction surface The frictional resistance between them prevents wear and abrasion of the material. [0003] In the field of coatings, people have higher and higher requirements for corrosion, and at the same time, some other properties must be taken into account, such as wear resistance, high strength, high hardness, etc., but it is difficult for current coatings to take into account these properties in the case of high corrosion resis...
