Abstract

The invention discloses heat-resistant lubricating grease and a preparation method thereof. The heat-resistant lubricating grease is prepared from poly-alpha-olefin synthetic oil, high-base-number synthetic petroleum calcium sulfonate, a transforming agent acetic acid, 12-hydroxystearic acid, boric acid, calcium hydroxide, sebacic acid, water, a phenolic antioxidant, a thiadiazole derivative, high-relative-molecular-mass liquid phenol and a regulator. And finally, adding the liquid phenol with high relative molecular mass into the prepared base lubricating grease to obtain a finished product. According to the heat-resistant lubricating grease and the preparation method thereof, the smaller the adding amount of the high-relative molecular mass liquid phenol is, the minimum lubricating friction factor is achieved, the best antifriction performance is achieved and is reduced by about 9% compared with that of traditional lubricating grease, the anti-aging capacity of the lubricating grease is improved, and the problem that when existing synthetic base lubricating grease is used for friction, the service life of the lubricating grease is prolonged is solved. The friction coefficient is large due to friction of rotation of a workpiece, so that the service life of the base grease is shortened.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a heat-resistant lubricating grease and a preparation method thereof. Background technique [0002] Lubricating oil is a technology-intensive product, which is a mixture of complex hydrocarbons, and its real performance is the combined effect of complex physical or chemical changes. The basic properties of lubricating oil include general physical and chemical properties, special physical and chemical properties and simulated bench tests. [0003] The existing synthetic lubricating grease wall traditional lubricating grease has good performance, and all of them are high temperature resistant. However, when the existing synthetic base lubricating grease is used for friction, the friction coefficient will be large due to the friction of the workpiece rotation, thereby reducing the base lubrication. Grease service life. Contents of the invention [0004] (1) Solved techni...
