Abstract

The invention provides long-service-life synthetic oil special for wind power gears. The long-service-life synthetic oil is prepared from base oil and an additive, wherein the adding amount of the additive is 4.341 to 9.752 percent of that of the base oil; the base oil is at least prepared from the following two components in percentage by weight: 80 to 90 percent of polyether and 10 to 20 percentof polyester; the additive is at least prepared from the following nine components in percentage by weight: 0.3 to 1 percent of octyl / butyl liquid diphenylamine, 0.5 to 1 percent of 2,6-p-ditertbutylp-cresol, 0.03 to 0.5 percent of benzotriazole aliphatic amine salt, 1 to 4 percent of dialkyl group dithio molybdenum trisulfate, 0.5 to 1.5 percent of tricresyl phosphate, 0.01 to 0.05 percent of amine-epoxide condensation compound, 0.001 to 0.002 percent of a compound antifoaming agent, 0.3 to 0.4 percent of a metal passivator and 1 to 2 percent of aliphatic ester. The clean and low-friction-coefficient PAG and polyester are taken as the base oil, and the multifunctional additive is added, so that the oil has the advantages of superior antifriction performance, low friction coefficient, high temperature resistance, excellent viscosity-temperature characteristic, high antifoaming performance, high oxidation stability, low pour point, high micro-pitting erosion resistance, safety and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a long-life synthetic wind power gear special oil and a preparation method thereof. Background technique [0002] In today's increasingly tense and scarce energy sources, people gradually realize the importance of renewable energy. As the most abundant clean energy in the world, wind energy has developed rapidly in recent years. China is rich in wind energy resources and has a large demand for electricity. Wind power generation is getting more and more attention. Gearboxes are the heart of wind power plants. Critical to the normal functioning of the whole. At present, the domestic gear oil is mainly mineral type or PAO type, which has high friction coefficient, high temperature and short service life. Contents of the invention [0003] In order to solve the above problems, the present invention provides a long-life synthetic wind power gear special oi...
