Problems solved by technology

[0003] For the gear oil used in generator sets, the current formula generally uses mineral oil and ordinary gear oil compounding agent for production. When used under extreme ambient temperature and harsh working conditions, a strong oil film cannot be formed on the tooth surface. Long-life oil cannot be achieved, and micro-pitting of the gear surface will inevitably occur
In this case, the gear oil prepared according to the current technology is not environmentally friendly, has limited use, and does not protect the gearbox enough to achieve long-life oil use.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an environment-friendly synthetic ester gear oil for wind power generators and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid lubricant used on various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. It is mainly composed of base oil and additives. Additives can add new properties to base oils or improve and improve the performance of lubricating oils. Industrial lubricating oil can be divided into lubricating oil for mechanical equipment and lubricating oil for metal processing. Among them, lubricating oil for mechanical equipment can be divided into hydraulic oil, steam turbine oil, gear oil, air compressor oil, guide rail oil, spindle oil, heat transfer oil , Transformer oil, vacuum pump oil, grea...
