Abstract

The invention discloses a highly-antiwear additive for lubricating oil. The highly-antiwear additive is characterized by consisting of the following components in percentage by weight: 10 to 26 percent of nanometer metal powder, 1 to 3 percent of dispersing agent, 0.5 to 1.5 percent of detergent, 0.5 to 1.5 percent of pour point depressant, 0.5 to 2 percent of oxidation and corrosion inhibitor, 1 to 4 percent of viscosity index improver and the balance of base oil, wherein the nanometer metal powder comprises copper powder, magnesium powder and boron powder; the dispersing agent may be polyisobutene bissuccinimide; the detergent may be sulfurized calcium alkyl phenolate or polyisobutene amine; the pour point depressant may be polymethacrylate; the oxidation and corrosion inhibitor may be a sulfurphosphorousbutyloctyl zinc salt; and the viscosity index improver may be an ethylene-propylene copolymer.

Description

(1) Technical field [0001] The invention relates to a lubricating oil antiwear additive, in particular to a high antiwear lubricating oil additive. (2) Background technology [0002] At present, many scientific research institutions are working hard to improve the efficiency of the engine. Therefore, higher requirements are put forward for the standard of lubricating oil, and the use of anti-wear additives can greatly improve the comprehensive performance of lubricating oil. However, the current domestic products are not effective, and high-quality lubricating oil anti-wear additives are relatively expensive in the international market. (3) Contents of the invention [0003] The present invention intends to solve the problems existing in the above-mentioned technologies, and provide a high anti-wear lubrication with obvious anti-wear and anti-friction for the engine, and has a strong repair function, without any corrosion effect on the inside of the machine, and at a lowe...
