Abstract

The invention relates to a compound additive for turbine oil. The compound additive is prepared from base oil, an antioxidant, a dispersant, a detergent, a rust inhibitor, a foam inhibitor, a metal deactivator, a demulsifier, a viscosity index improver, an extreme pressure additive, tungsten oxide powder and molybdenum oxide powder. According to the compound additive, the preparation method is simple, waste oil is biodegradable, the environment-friendly requirements are fully met, and the use cycle of the product is longer; and the antiwear and extreme pressure resisting effects of lubricating oil are improved, meanwhile, multiple functions, i.e., oxidation resistance, corrosion resistance and foaming resistance of the lubricating oil are improved, and the detergency effect of the lubricating oil is kept durably, so that the comprehensive effect of the engine lubricating oil can be fully improved.

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 the composite additive in 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...
