Abstract

The invention discloses a composite additive for turbine oil. The composite additive comprises base oil, an anti-oxidant, a rusting inhibitor, a foam inhibitor, a metal deactivator, an extreme pressure additive, a demulsification agent, copper oxide powder and magnesium metal powder. The anti-oxidant is a mixture of diarylamine and alkylphosphite. The rusting inhibitor is ethoxyphenol. The foam inhibitor is polydimethylsiloxane. The metal deactivator is toluyltriazole derivative. The extreme pressure additive comprises alkyl phosphate ester and salt. The demulsification agent is polyalkoxypolyol. The composite additive comprises, by weight, 12-14% of the anti-oxidant, 9-11% of the rusting inhibitor, 7-9% of the foam inhibitor, 10-12% of the metal deactivator, 6-8% of the extreme pressure additive, 11-13% of the demulsification agent, 1-2% of the copper oxide powder, 1-2% of the magnesium metal powder and the balance the base oil. The composite additive is prepared by the simple processes, has a price lower than those of the same types of other products, has high quality, effectively and comprehensively improves performances of the turbine oil, prolongs a use period of the turbine oil, improves turbine oil extreme pressure resistance, comprehensively improves oxidation resistance, corrosion resistance, foam resistance and oily sludge resistance of the turbine oil, is biodegradable and completely exceeds environmental requirements on the same type of the existing products.

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] With the continuous development of human civilization, the continuous development of science and technology, and the environmental requirements of human beings for living space, all countries in the world are working hard to maintain environmental quality and air quality. They are all striving to develop in the direction of energy saving and emission reduction, effectively improving the quality and quality of existing turbine oil, and prolonging the service life. The current performance requirements for turbine oils are to ensure the following performance: [0003] 1. Provide bearing lubrication. [0004] 2. Take away heat through circulation. [0005] 3. Act as hydraulic fluid on the regulating mechanism and other control devices. [0006] 4...
