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 discloses engine lubricating oil which consists of base oil, an antioxidant, a detergent, a dispersing agent, an extreme-pressure anti-wearing agent, a viscosity index improver, a nano-grade rhenium-molybdenum alloy powder material, polyacrylate, an ethyoxyl phenol, benzotriazole and vulcanized dipolybutylene, wherein the antioxidant is a sulfur-phosphorus alkylphenol zinc salt; the detergent is sulfurized calcium alkyl phenolate; the dispersing agent is succinate; the extreme-pressure anti-wearing agent is a sulfo-ester; the viscosity index improver is a polyethylene diene copolymer. The engine lubricating oil has the advantages of being scientific in preparation scheme and simple in preparation method, the price of a prepared product is lower than that of a similar product, various property requirements of the engine lubricating oil can be effectively and comprehensively improved, the oxidation resistance, the corrosion resistance, the detergence and dispersity, the anti-rusting property, the bubble resistance and the greasy sludge prevention property of the engine lubricating oil can be comprehensively improved, the effects of wearing resistance and extreme pressure resistance can be improved to the maximum extent, meanwhile a very good remediation function on a wearing surface of an engine can be achieved, the lubricating oil change period can be prolonged, the noise can be reduced, and the exhaust gas emission can be reduced.

Description

[0001] (1) Technical field [0002] The invention relates to a lubricating oil, in particular to a preparation scheme and a manufacturing method of an engine lubricating oil. [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 are many re...
