Abstract

The invention relates to a composite additive applied to engine oil. The composite additive is composed of base oil, an antioxidant, a dispersant, a cleaning agent, a corrosion inhibitor, a foaming inhibitor, a metal passivator, a demulsifying agent, a viscosity index improver, an extreme pressure additive, tungsten oxide powder, and molybdenum oxide powder. The composite additive has the advantage of simple production method, waste oil is biodegradable, an environmental protection requirement is completely reached, the usage period of a product is longer, antiwear and anti-extreme pressure efficacies of lubricating oil are improved; a plurality of efficacies of oxidation resistance, corrosion resistance and foaming resistance of the lubricating oil are increased simultaneously, a cleanliness efficacy of the lubricating oil can be maintained for a long term, and the comprehensive efficacy of the lubricating oil of an engine can be completely enhanced.

Description

(1) Technical field [0001] The invention relates to a composite additive for engine oil, in particular to a preparation scheme and a manufacturing method for a composite additive for engine oil. (2) Background technology [0002] At present, engine oil occupies almost half of the lubricating oil market. In 2013, the number of automobiles in my country has exceeded 100 million, so it has received great attention from people. 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, the lubricating oil should have good fluidity to ensure the lubrication of moving parts in time. At high temperature, the lubricating oil should better isolate the moving parts to reduce wear. Lubricating oil plays a lubricating role by reducing friction and removing heat from the friction surface. The pollutants accumulated during the operation of the engine wi...
