preparation example Construction
[0070] Another aspect of the present invention provides a kind of preparation method of fully synthetic wind power generator gear box oil, comprises the steps:
[0071] Add 2 / 3 base oil into a clean reactor, and raise the temperature of the reactor to 60°C,
[0072] Add extreme pressure agent, friction reducer, antioxidant, dispersant and rust inhibitor in sequence,
[0073] After stirring for 30 minutes, add anti-emulsion agent and continue stirring for 30 minutes;
[0074] Add the remaining 1 / 3 base oil into the reactor and lower the temperature to 35°C;
[0075] The product is obtained after being filtered by a filtering device.
Embodiment 1
[0077] In a dry and clean reactor, add 2 / 3 mixed base oil, heat up to 60°C, add 1% polysulfide extreme pressure agent, 1% sulfur phosphorus nitrogen compound extreme pressure agent, 0.15% alkyl phosphate Amine salt, 0.1% organic tungsten extreme pressure agent, 2.0% PTFE emulsion friction reducer, 0.2% phenolic antioxidant and 0.2% amine antioxidant, 3.8% dispersant, 0.5% Benzotriazole derivative metal deactivator, stirring for 30 minutes, then adding 0.05% polyether anti-emulsion agent and stirring for 30 minutes, then adding the remaining 1 / 3 base oil, wherein the total mass percentage of mixed base oil is 91%, Cool down to 35°C and filter through a filter to obtain the product.
Embodiment 2
[0079] In a dry and clean reactor, add 2 / 3 mixed base oil 2, heat up to 60°C, add 0.75% polysulfide extreme pressure agent, 1.75% sulfur phosphorus nitrogen compound extreme pressure agent, 0.2% alkyl phosphate Amine salt, 0.15% organic tungsten extreme pressure agent, 1.5% PTFE emulsion friction reducer, 0.2% phenolic antioxidant and 0.2% amine antioxidant, 3.7% dispersant, 0.5% Benzotriazole derivative metal deactivator, stirring for 30 minutes, then adding 0.05% polyether anti-emulsion agent and stirring for 30 minutes, then adding the remaining 1 / 3 base oil, wherein the total mass percentage of mixed base oil is 91%, Cool down to 35°C and filter through a filter to obtain the product.

Abstract
The present invention relates to a full-synthetic wind power generation gear oil, which at least comprises: 91% of a mixed base oil, 2.25-3.45% of an extreme pressure agent, 1-2% of a polytetrafluoroethylene emulsion friction reducer, 3.6-3.8% of a dispersant, 0.5% of a benzotriazole derivative metal deactivator, 0.4% of an antioxidant, and 0.05% of a polyether-based demulsifier. According to the present invention, the full-synthetic wind power generation gear oil uses the new specially-synthesized material polyester having the high viscosity index and the oil-soluble polyether, has advantages of excellent viscosity-temperature performance, good micro-pitting resistance, prominent gear cleanliness, excellent high-temperature lubricating property and excellent low-temperature fluidity, can effectively reduce the downtime number of the wind turbine due to the change of the ambient temperature, can improve the operation efficiency of the wind turbine, can substantially prolong the oil change maintenance period and the service life of the wind power gear speed increasing box, and can objectively achieve the energy saving and the environmental protection.
Description
technical field [0001] The invention relates to a lubricating oil composition, in particular to a fully synthetic gear oil for wind power generation, and belongs to the technical field of lubricating oils. Background technique [0002] At present, in my country's energy composition, the installed capacity of wind power has surpassed that of nuclear power, becoming the third largest energy source in China. China's installed wind power capacity will reach 230 million kilowatts by 2020. In the near future, China is expected to become the world's largest producer of wind power. To keep wind turbines running smoothly, lubricating oil plays a vital role. But at present, wind power lubricating oil mainly relies on foreign imports, and the domestic market has great prospects for development. [0003] The fan has several main lubricating parts, including the gear oil of the main gearbox, the pitch and yaw gearbox, the grease of the main shaft bearing and the generator bearing, and...
