High antiwear lubricating oil and preparation method thereof

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.

Description

(1) Technical field [0001] The invention relates to a lubricating oil, in particular to a wear-resistant lubricating oil and a manufacturing method thereof. (2) Background technology [0002] With the development of engine technology, higher requirements are put forward for the performance of engine lubricating oil, and the improvement of lubricating oil quality mostly depends on lubricating oil additives, that is, in lubricating oil production, it is often necessary to improve lubricating oil by adding additives In order to increase the anti-wear effect of lubricating oil, it is often necessary to add lubricating oil anti-wear additives to lubricating oil. At present, the anti-wear additives added to lubricating oil have certain anti-wear effects, but the use effect is not good. Ideal, and long-term use will increase the carbon deposits in the engine, even lose lubricating oil, and cause corrosion damage to the engine; anti-wear additives with better anti-wear effects are m...
