Anti-wearing extreme-pressure-resistant lubricating oil

Abstract

The invention discloses anti-wearing extreme-pressure-resistant 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, a thyoxyl phenol, benzotriazole and vulcanized dipolybutylene, wherein the antioxidant is shielding bisphenol; the detergent calcium-based phenolate; the dispersing agent is sodium polyacrylate; the extreme-pressure anti-wearing agent is chlorinated paraffin; the viscosity index improver is a styrene diene copolymer. The anti-wearing extreme-pressure-resistant 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 anti-wearing extreme-pressure-resistant 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 anti-wearing extreme-pressure-resistant 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 anti-wear and anti-extreme pressure 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 import...
