Abstract

The invention relates to a composite additive used for turbine oil. The composite additive is composed of base oil, an anti-oxidant, a dispersant, a clearing agent, a corrosion inhibitor, an anti-foaming agent, 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, the product can completely reach environmental protection requirement, the usage period of the product is long, anti-wear and anti-extreme pressure performances can be increased; a plurality of efficacy of anti-oxidation, corrosion resistance and foaming resistance of the composite additive can be increased simultaneously, cleanliness effect of the composite additive can be maintained for long term, and comprehensive efficacy of the composite additive can be completely enhanced.

Description

(1) Technical field [0001] The invention relates to a composite additive for turbine oil, in particular to a preparation scheme and a manufacturing method for a composite additive for turbine 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 ...
