Abstract

The invention relates to a complex aluminum-based grease composition, in particular relates to a high-temperature grease composition of a tungsten-containing compound and a preparation method thereof. The complex aluminum-based grease composition comprises a base grease composition consisting of the following components in percentage by weight: 80-95% of base oil and 5-20% of composite aluminum-based thickening agent; based on the total weight of the base grease composition, the complex aluminum-based grease composition further comprises the following components in percentage by weight: 0.1-5% of nanometer tungsten disulfide (WS2), 0.1-5% of oil-soluble organic tungsten compound, and 0.5-2% of anti-oxygen preservative. The composite aluminum soap thickening agent is generated through reaction among aromatic acid, fatty acid and aluminum isopropoxide tripolymer. According to the invention, since the nanometer WS2 and the oil-soluble organic tungsten are added to the complex aluminum-based grease, excellent extreme-pressure anti-wear property is achieved,and high-temperature load-carrying property and anti-oxidation property of the grease can be improved.

Description

technical field [0001] The invention relates to a composite aluminum-based lubricating grease composition, in particular to a high-temperature lubricating grease composition containing a tungsten compound and a preparation method thereof. [0002] Background technique [0003] Composite aluminum-based grease has the advantages of high dropping point and good oxidation resistance, and is a high-temperature resistant grease with excellent performance. At the same time, it has excellent high temperature reversibility, can be used for a short time under extreme high temperature without changing the performance of the grease, and has good pumpability and good water resistance, especially suitable for the needs of centralized lubrication. Therefore, the application of composite aluminum-based grease is very extensive. However, its extreme pressure and antiwear performance needs to be improved. Contents of the invention [0004] Aiming at the deficiencies of the above-ment...
