Abstract

The invention provides a compound additive for an engine oil. The compound additive for the engine oil is characterized by comprising a base oil, a dispersing agent, a cleansing agent, an anti-wear agent, an antioxidant, a viscosity index improver, a pour point depressant, an anti-foaming agent, a demulsifying agent and metal titanium powder. The dispersing agent is polyisobutene polybutanimide; the cleansing agent is vulcanized phenoxide; the anti-wear agent is alkyl containing phosphate and salt; the antioxidant is zinc dialkyl dithiophosphate; the viscosity index improver is ethylene-propylene copolymer; the pour point depressant is vinylethylene copolymer; the anti-foaming agent is polyalkylmethacrylate copolymer; and the demulsifying agent is polyoxyalkylene polyamine. The components comprise 9-11% of dispersing agent, 9-10% of cleansing agent, 6-8% of anti-wear agent, 14-15% of antioxidant, 5-6% of viscosity index improver, 4-5% of pour point depressant, 8-9% of anti-foaming agent, 11-12% of demulsifying agent, 2-3% of metal titanium powder and the balance of base oil in percentage by weight. The compound additive of the engine oil, provided by the invention, has the advantages of simple manufacturing method, economic efficiency, practicability, low price of the manufactured product, high quality, capability of prolonging the life cycle of the lubricating oil, improving the anti-wear and extreme pressure resistant effects of the lubricating oil and enhancing multiple effects of oxidation resistance, corrosion resistance and foaming resistance of the lubricating oil, long-term retention of cleansing effect of the lubricating oil and capability of comprehensively enhancing the comprehensive 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 for a composite additive for engine 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 particles, sludge, carb...
