Description

technical field [0001] The invention relates to the technical field of lubricating oil and its preparation method, in particular to a composite graphene-based wind power bearing lubricating oil and its preparation method. Background technique [0002] Wind power, as a renewable green and environmentally friendly new type of clean energy, has developed rapidly in recent years. Wind power bearings are the core components of wind turbines. Wind power bearings are used in harsh outdoor conditions all year round, and the temperature, humidity, and bearing load vary greatly. Especially, strong winds will generate high impact loads. Therefore, the lubrication of wind power bearings is extremely important. Bearing lubricating oil is the lubricating oil used on the bearing to lubricate, cool down, resist pressure, and prolong the life of the bearing. Wind power bearing lubricating oil requires extremely high load carrying capacity, lubricating performance, and long life to avoid fr...
