Abstract

The invention discloses antioxidant wear-resistant lubricating oil used for automobiles. The antioxidant wear-resistant lubricating oil used for automobiles comprises the following raw materials: modified nano-diamond, mineral base oil, synthetic base oil, an organic molybdenum mixture, alkyl diphenylamine, methylene-bis-alkyl dithiocarbamate, a sulfur-phosphorus-nitrogen type extreme pressure agent, a detergent dispersant, azelaic acid, neopentyl glycol, a pour point reducer, synthetic ester, a viscosity index improver, fluorosilicone oil, vinyl pyrrolidone, fumarate, an anti-foaming agent, sodium bentonite and sasol wax. The alkyl diphenylamine is used in lubricating oil used for automobiles, so that the oxidative decomposition of effective constituents in the lubricating oil can be inhibited, the viscosity index of the oil product can be further improved, and simultaneously the lubricating oil is further mixed with methylene-bis-alkyl dithiocarbamate, the sulfur-phosphorus-nitrogentype extreme pressure agent, the anti-foaming agent, sodium bentonite and sasol wax, so that the obtained lubricating oil has appropriate viscosity, excellent extreme pressure property and oxidation stability, abrasion resistance and excellent lubricating effect, the friction can be reduced effectively, the loss is reduced, and the friction performance is improved.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an anti-oxidation and wear-resistant lubricating oil for vehicles and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. At present, there are many solid lubricants with good performance, but due to their high density, they cannot be suspended in the oil, and the particle size is too coarse to get into the friction pair. The agglomeration is serious, and the oil passage is blocked after a long time, so they cannot be used in lubricating oil. [0003] The amount of petroleum lubricating oil accounts for more than 90% of the total amount, so lubricating oil often refers to petroleum ...
