Abstract

The invention provides a composite additive applied to engine oil. The composite additive comprises the following components: base oil, an anti-oxidant, 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. A method for producing the composite additive is simple, waste oil is biodegradable, environmental protection requirements are completely met, usage period of the product is elongated, abrasion and extreme pressure resisting efficacy of lubricating oil is improved, oxygen resistance, corrosion resistance, foaming resistance, and other efficacies of lubricating oil are improved, cleaning effects of the lubricating oil are kept for a long time, and comprehensive efficacies of the engine lubricating oil are completely improved.

Description

(1) Technical field [0001] The invention relates to an engine oil compounding agent, in particular to a preparation scheme and a manufacturing method for an engine oil compounding agent. (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 will affec...
