Abstract
The invention relates to the technical field of lubricating grease, and discloses lubricating grease, a raw material composition thereof, a preparation method and application, wherein the raw material composition of the lubricating grease comprises the following components in parts by weight: 75 to 90 parts of base oil, 4 to 18 parts of thickening agent, 1 to 6 parts of extreme pressure agent, 0.1 to 5 parts of antirust agent, 1 to 6 parts of nano molybdenum disulfide, 0.1 to 2 parts of preservative and 0.1 to 2 parts of antioxidant; the base oil is selected from one or more of hydrocarbon oil and ester oil; the thickener is a bisureido thickener; the extreme pressure agent is a sulfur compound; the antirust agent is sulfonate. The lubricating grease disclosed by the invention is prepared from the lubricating grease raw material composition through processing. The lubricating grease provided by the invention has the characteristics of low friction coefficient, high extreme pressure property and high wear resistance.
Description
Technical Field
The invention relates to the technical field of lubricating grease, in particular to lubricating grease, a raw material composition thereof, a preparation method and application thereof.
