Abstract
The invention belongs to the field of gear oil, and particularly relates to long-life wind power gear oil, which comprises the following raw materials in percentage by mass: 1 to 2 percent of extreme pressure agent, 1 to 3 percent of antiwear agent, 0.1 to 1 percent of antioxidant, 0.1 to 0.5 percent of metal deactivator, 0.2 to 0.8 percent of antirust agent, 0.1 to 0.5 percent of demulsifier, 0.1 to 0.2 percent of defoamer, 0.3 to 0.5 percent of modified nano additive and the balance of base oil. The extreme pressure agent adopts the sulfurized isobutene, the antiwear agent adopts the mixture of the phosphorothioate derivative and the organic molybdenum, and the gear oil has micro pitting corrosion resistance through the mutual coordination of the sulfurized isobutene, the phosphorothioate derivative, the organic molybdenum and the modified nano additive, can be well mutually dissolved and mixed with the fully-synthesized base oil, delays the abrasion of the gear, and prolongs the service life of the gear.
