Zusammenfassung:The invention relates to a perfluoropolyether lubricating grease and a preparation method thereof. The lubricating grease is composed of the following components, by weight: 60-80% of fluorine-containing base oil, 10-30% of a thickening agent, 0.3-1.0% of an antioxidant, 2-6% of a rust inhibitor, and 3-8% of an anti-wear extreme pressure agent. The invention also discloses a preparation method of the lubricating grease. With the perfluoropolyether lubricating grease, friction during a gear operation process can be reduced; gear corrosion degree can be reduced; rolling bearing high-temperature performance can be improved; rolling bearing low-temperature operation noise can be reduced; and environment pollution can be reduced.
