Abrasion-proof lubricant oil and method of producing the same

Abstract

The invention relates to an antiwear lubricant, which is prepared by mixing, temperature rise, stirring and filtration of basic oil, an antiwear additive, a dispersant, a cleaning agent, a pour inhibitor, a corrosionproof antioxidant and a viscosity index modifier, wherein the antiwear additive is nanometer metallic powder and comprises ferric oxide powder, copper alloy powder, magnesium powder, manganese powder and boron powder; the dispersant is polyisobutylene dibutyl imide or polyisobutylene n-butyl imide; the cleaning agent is calcium mahogany sulfonate or vulcanized calcium alkyl powder; the pour inhibitor is polymethacrylate; the corrosionproof antioxidant is zinc butyl octyl dithiophosphate; and the viscosity index modifier is ethylene and propylene copolymer. The antiwear lubricant comprises the following compositions in percentage by weight: 25 to 30 percent of the antiwear additive, 0.5 to 2.5 percent of the dispersant, 0.4 to 1 percent of the cleaning agent, 1 to 5 percent of the antiwear agent, 0.1 to 0.5 percent of the pour inhibitor, and the balance being the basic oil. The preparing method is simple and practical; and the lubricant prepared has low cost, obvious antiwear effect, anti-attrition effect and restoration function, and does not corrode insides of machines.

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 rapid 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 add additives to Improve the performance and quality of lubricants. In order to increase the anti-wear effect of lubricating oil, it is often necessary to add anti-wear additives to lubricating oil. At present, the anti-wear additives (whether domestic or imported) added to lubricating oil have certain anti-wear effects, but the use effect is not ideal. Moreover, long-term use will increase the carbon deposits in the engine, even lose lubricating oil, and cause corrosion damage to the engine; anti-wear...

In order to increase the anti-wear effect of lubricating oil, it is often necessary to add anti-wear additives to lubricating oil. At present, the anti-wear additives (whether domestic or imported) added to lubricating oil have certain anti-wear effects, but the use effect is not ideal. Moreover, long-term use will increase carbon deposits in the engine, or even lose lubricating oil, and cause corrosion damage to the engine; anti-wear additives with better anti-wear effects are more expensive
