Lubricating oil additive containing thiadiazole derivatives and nano copper, preparation method of additive and lubricating oil containing additive

The invention belongs to the field of chemical engineering, and relates to a lubricating oil additive containing thiadiazole derivatives and nano copper, a preparation method of the additive and lubricating oil containing the additive. The lubricating oil additive comprises the following ingredients: the thiadiazole derivatives, the nano copper, mercaptan, isopropanol, 30wt% formaldehyde solution, rare-earth chloride, alkali liquor and substituted phenol. On the basis of base oil, the thiadiazole derivatives, the modified nano copper and a number of relevant preparations are added, wherein the functional group of the thiadiazole derivatives and the nano copper can form chemical bonds such as coordinate bonds and hydrogen bonds, the two substances can be stably dispersed in the lubricating oil, adsorption of the two substances on the surface of metal can also be improved, and the beneficial effects of the lubricating oil are improved. 本发明属于化工领域，涉及种含有噻二唑衍生物和纳米铜的润滑油添加剂，添加剂的制备方法，及含有该添加剂的润滑油，包括以下成分：噻二唑衍生物、纳米铜、硫醇、异
