Abstract
The invention relates to antiwear lubricating oil prepared by mixing, heating, stirring and filtering 3%-6% of antiwear additive, 1%-2.5% of dispersant, 0.5%-1% of detergent, 0.5%-1% of pour point depressant, 0.5%-1% of anti-corrosion antioxygen, 2%-4% of viscosity index improver and the balance of base oil, wherein the antiwear additive is nanoscale metal powder and comprises ferric oxide powder,copper powder, chromium powder, manganese powder and boron powder; the dispersant is polyisobutene-multi-succinimide; the detergent is calcium mahogany sulfonate or sulfurized calcium alkyl phenolate; the pour point depressant is polymethylacrylic acid ester; the anti-corrosion antioxygen is butyl-octyl zinc thiophosphate; and the viscosity index improver is ethylene-propylene copolymer. A preparation method is simple and practical; in addition, the prepared lubricating oil has low cost, obvious antiwear and wear-reducing effects, repairing function, no corrosion effect inside a machine.
