Compounding agent for preparing engine lubricating oil

Abstract

A compounding agent for preparing engine lubricating oil is disclosed, and is characterized by being composed of base oil, a disperser, a detergent, an antiwear agent, an antioxidant, a viscosity index improver, a pour point depressant, an anti-foaming agent, a demulsifier, a metal magnesium powder and a metal chromium powder. The disperser is polyisobutene succinimide; the detergent is a phosphate; the antiwear agent is alkyl containing phosphatide and salt; the antioxidant is ainc dialkyl dithiocarbamate; the viscosity index improver is an ethylene-propylene polymer; the pour point depressant is a vinyl-ethylene polymer; the anti-foaming agent is an alkyl acrylate copolymer; and the demulsifier is poly-alkoxyl polyol. The compounding agent for preparing engine lubricating oil comprises the following components in percentage by weight: 12-13% of the disperser, 12-13% of the detergent, 4-5% of the antiwear agent, 14-15% of the antioxidant, 4-5% of the viscosity index improver, 7-8% of the pour point depressant, 6-8% of the anti-foaming agent, 9-10% of the demulsifier, 1-2% of the metal magnesium powder, 1-2% of the metal chromium powder, and the balance of base oil. A method for manufacturing the compound additive for engine lubricating oil disclosed by the invention is simple, economic and practical; and the manufactured product is low in price, high in quality, and capable of prolonging the service cycle of the lubricating oil, enhancing the antiwear and extreme-pressure-resisting effects of the lubricating oil, improving the various effects of oxidization resistance, corrosion resistance and forming resistance of the lubricating oil, keeping the clean effect of the lubricating oil for a long time, and comprehensively enhancing the integrated effect of the engine lubricating oil.

Description

(1) Technical field [0001] The invention relates to a lubricating oil additive, in particular to a preparation scheme and a manufacturing method of a compounding agent for preparing engine lubricating oil. (two) background technology: [0002] Engine oils account for almost half of the lubricating oil market and thus receive great attention. The main function of engine oil is to extend the life of the machine and ensure the normal operation of the machine under different speed, temperature and pressure conditions. At low temperature, lubricating oil should have good fluidity to ensure the lubrication of moving parts in time; at high temperature, lubricating oil should be able to better isolate moving parts to reduce wear. Lubricating oil plays a lubricating role by reducing friction and taking away heat from the friction surface. The pollutants accumulated during the operation of the engine will affect the normal operation of the engine. These pollutants may be abrasive par...

Problems solved by technology

However, the current various lubricating oil additives are of good quality and expensive, and many low-priced ones are not effective.

And with the progress of society and the development of human science and technology, engine oil must also have a great development, because the current oil change mileage itself is a huge waste of energy
