Abstract

The invention relates to a compound additive of lubricating oil, which is characterized by comprising 2%-10% of nanoscale metal powder, 0.5%-2.5% of polyisobutene-bis-succinimide, 0.5%-1.5% of sulfurized calcium alkyl phenolate, 0.2%-1.5% of polymethylacrylic acid ester, 0.5%-2% of butyl-octyl zinc thiophosphate and 1%-5% of ethylene-propylene copolymer and the balance of base oil, wherein the nanoscale metal powder comprises copper oxide powder, magnesium powder and manganese powder. A preparation method is simple and practical; in addition, the prepared compound additive has low cost, playsa good abrasion resistant effect on various base oils and has good repairing function without corrosion effect to the inside of a machine.

Description

(1) Technical field [0001] The invention relates to a compound additive for lubricating oil. In particular, it relates to a multifunctional composite additive for lubricating oil and a manufacturing method thereof. (2) Background technology [0002] At present, lubricating oils on the market need to add various additives during the manufacturing process. Such as anti-wear agent, detergent, dispersant, anti-corrosion antioxidant, viscosity index improver and pour point depressant, etc. Waste of work and time, high cost, and long-term use often increases engine carbon deposits, and even causes engine corrosion and damage. (3) Contents of the invention [0003] The object of the present invention is to solve the problems in the above-mentioned technologies, and provide a multi-functional lubricating oil compound additive with obvious anti-wear, anti-friction, and repair functions to the engine, no corrosion effect on the inside of the machine, low cost, and a manufacturing ...
