Abstract

The invention discloses a lubricating oil composition, which is composed of, by mass, 85-95% of perfluoropolyether and 5-15% of boron nitride. The lubricating oil composition provided by the invention has the advantages of good lubricating performance and high stability in an oxygen-enriched environment, and is especially suitable for lubrication of the inner surface and structure of equipment exposed to the oxygen-enriched environment.

Description

technical field [0001] The present invention relates to a lubricating oil composition. Background technique [0002] Existing patents describe a number of fluorinated oil-based grease formulations, including perfluoropolyether oils. In synthetic grease formulations, these fluorinated oils, including perfluoropolyether oils, can be thickened with organic thickeners, such as polytetrafluoroethylene. Inorganic thickeners such as aluminum nitride, boron nitride and silicon carbide can also be used. Whether oil or grease, perfluoropolyether-based components are characterized by high temperature stability, chemical and oxidation resistance, good lubricity and compatibility with a wide range of materials such as plastics, metals and rubbers. [0003] US Pat. No. 7,838,475 discloses a composition consisting of an aromatic perfluoropolyether oil, preferably a halogenated oil, further preferably containing a thickening agent. This component can be used as lubricating oil itself, or...
