Problems solved by technology

In recent years, with the rapid development of the wind power industry, the moving parts of the wind power have become more and more heavily loaded, running faster, requiring longer service life and better stability. Ordinary lubricating greases have become It is increasingly unable to meet the needs of wind power equipment
The service life of the fully synthetic lubricating grease thickened with composite metal soap currently used is about three years, and it is extremely unstable. Because most of the wind power equipment is located at a disadvantage in traffic, it causes a huge waste of manpower and material resources for its repair and maintenance. Wind power equipment is urgently needed. Long-life high-efficiency grease is required

Abstract

The invention discloses a long-life fluorine lubricating grease for wind power generation, which is composed of base oil, a thickening agent and an additive, wherein the base oil is one or more of perfluoro polyether oil, perfluoro ester oil, perfluoro hydrocarbon oil and perfluoro silicone oil; the thickening agent is one or more of composite metal soap, inorganic soap, polytetrafluoroethylene, perfluoro-ethylene-propylene copolymer, fluorocarbon wax, carbon black, silicon dioxide, titanium dioxide, molybdenum disulfide, rare earth fluoride, nano graphite, fluoridized graphite and fluoridized resin; and the additive is one or more of antioxidant, anti-corrosion antirusting agent, extreme-pressure passivating agent, metal passivator, and AD complexing agent. With the use of the lubricating grease, the oil draining period of the lubricating parts in the wind power generation industry is improved by 3-10 times; and the lubricating grease is suitable for lubricating of all-weather corroded and other harsh environments, and greatly saves materials and manpower.

Description

technical field [0001] The invention relates to a lubricating grease, in particular to a long-life wind power fluorine lubricating grease, which belongs to the technical field of lubricating oil. Background technique [0002] Lubricants are mainly lubricating oils and greases. The ingredients are thickeners and additives added to the base oil. Usually lubricants use different components in different fields. Most of the wind power industry uses grease. In recent years, with the rapid development of the wind power industry, the moving parts of the wind power have become more and more heavily loaded, running faster, requiring longer service life and better stability. Ordinary lubricating greases have become It is increasingly unable to meet the needs of wind power equipment. The service life of the fully synthetic lubricating grease thickened with composite metal soap currently used is about three years, and it is extremely unstable. Because most of the wind power equipment is...
