[0003] There are few reports about wind power gear oil in China. The base oil of patent CN 103113968 A "Wind Power Gear Oil Composition" uses a mixture of polyalphaolefin and ester base oil, because ester oil has good biodegradability and hydrolysis , which also makes it difficult to perform long-term lubrication work
Patent CN 102604729 A "A Wind Battery Lubricating Oil Composition" uses II / III type mineral oil, polyolefin compound and alkyl naphthalene as the base oil to produce a semi-synthetic wind power gear oil, which is relatively cost-effective, but Due to the limitation of the operating environment of wind power equipment, it is inevitable that water will enter the gear oil during use, which will greatly affect the performance of wind power gear oil

Embodiment 1

[0046] The preparation method of the long-life anti-micropitting wind power gear oil of the present invention is as follows: add 1 / 2 synthetic base oil into the blending kettle, heat up to 85°C±5°C, add antioxidant V887E (0.1%) and RC7115 (0.2 %) and then stirred continuously for 1h. Add the remaining base oil, keep the temperature at 60°C and add the compounding agent (5.5%), continue stirring for 30 minutes, add molybdenum dialkyldithiocarbamate (0.3%), continue stirring for 30 minutes, and cool to obtain the finished product.

Embodiment 2

[0048] The preparation method of the long-life anti-micropitting wind power gear oil of the present invention is as follows: add 1 / 2 synthetic base oil into the blending kettle, heat up to 85°C±5°C, add antioxidants V887E (0.15%) and RC7115 (0.15%) %) and then stirred continuously for 1h. Add the remaining base oil, keep the temperature at 60°C and add the compounding agent (4%), continue stirring for 30 minutes, add molybdenum dialkyldithiocarbamate (0.5%), continue stirring for 30 minutes, and cool to obtain the finished product.

Embodiment 3

[0050] The preparation method of the long-life anti-micropitting wind power gear oil of the present invention is as follows: add 1 / 2 synthetic base oil into the blending kettle, heat up to 85°C±5°C, add antioxidant V887E (0.2%) and RC7115 (0.1 %) and then stirred continuously for 1h. Add the remaining base oil, keep the temperature at 60°C and add the compounding agent (3%), continue stirring for 30 minutes, add molybdenum dialkyldithiocarbamate (0.8%), continue stirring for 30 minutes, and cool to obtain the finished product.

Abstract

The invention discloses long-service-life anti-micro-pitting wind power gear oil and a preparation method thereof. The long-service-life anti-micro-pitting wind power gear oil is prepared from the following raw materials in mass by percent: 3 to 6 percent of industrial gear oil complexing agent, 0.1 to 0.3 percent of antioxidant, 0.1 to 1 percent of antiwear additive, and the balance of basic oil. The long-service-life anti-micro-pitting wind power gear oil has the advantages of micro-pitting resistance, good cleanliness, good wear resistance, good low temperature performance, good oxidation stability, good shearing resistance and the like; and particularly, the excellent performance is still remained in the presence of water. Good performance can be well maintained when the long-service-life anti-micro-pitting wind power gear oil is used for a long time.

Description

technical field [0001] The invention relates to the field of industrial gear oil, in particular to a long-life anti-micropitting wind power gear oil. Background technique [0002] With the advancement of science and technology, the demand for energy is increasing day by day, and the excessive utilization of non-renewable energy has caused many problems, such as the free emission of greenhouse gases and the aggravation of climate warming. Human beings urgently need renewable energy to replace traditional non-renewable energy. Wind energy is a renewable natural energy that does not produce any pollution emissions. Wind power generation technology is relatively mature, and it is the main new power source for the sustainable development of human society and economy in the 21st century. The European Wind Energy Association's global strategic goal for 2020 is that wind power stations will account for 12% of global electricity. Three types of lubricating oil are mainly used in wi...
