Problems solved by technology

Therefore, high-quality lubricating oils on the market are expensive, and lubricating oils with ideal prices are mostly single-function, unsatisfactory in use, and the oil change interval cannot meet the basic requirements of the engine.
In order to pursue the ideal profit and find selling points for the products, some production units only pay attention to the high anti-wear properties of the products, while ignoring the anti-oxidation, anti-corrosion and clean dispersibility of the lubricating oil itself.

Abstract

The invention provides a lubricating oil for an engine. The lubricating oil is composed of base oil, an anti-oxidant, a detergent additive, a dispersing agent, an anti-wear reagent at extreme pressure, a viscosity index improver, nanometer rhenium-molybdenum alloy powder, polyacrylate, ethoxyphenol, benzotriazole and sulfurized dipolybutene, wherein the anti-oxidant is aromatic amine; the detergent additive is salicylate; the dispersing agent is succimide; the anti-wear reagent at extreme pressure is diaryl disulfide; and the viscosity index improver is an alkene copolymer. The lubricating oil provided by the invention has the advantages that a preparation scheme for the lubricating oil is scientific; a manufacturing method for the lubricating oil is simple; the prepared lubricating oil is lower in price compared with products of a same kind; each performance of the lubricating oil is comprehensively improved; the anti-wear and anti-extreme pressure performance of the lubricating oil are maximally enhanced while corrosion resistance, cleaning performance, dispersing performance, rust resistance, foaming resistance and resistance to generation of greasy filth are improved; and the lubricating oil exerts strong repair effect on the magic surface of the engine, prolongs an oil change period, reduces noise and decreases discharge of tail gas.

Description

[0001] (1) Technical field [0002] The invention relates to a lubricating oil, in particular to a preparation scheme and a manufacturing method of the lubricating oil used in engines. [0003] (2) Background technology [0004] At present, the lubricating oil industry has made great progress, especially with the continuous development of society and the continuous improvement of science and technology, as well as the technological innovation of various new and old equipment, the development of the automobile industry is more prominent, so the lubricating oil industry for It is necessary to continuously research and develop and innovate to make the efficacy of various mechanical equipment meet higher design requirements. At present, due to the continuous development of the automobile industry, engine lubricants occupy half of the market for lubricants, so it has been favored by various lubricant manufacturers. And scientific research units attach great importance to it. There a...
