Abstract

The invention provides a high-temperature lubricating grease composition and a preparation method. The preparation method comprises the following steps of adding boron nitride and an anti-wear reagent at extreme pressure into base oil according to a certain proportion, mixing, heating to 60-160 DEG C, carrying out pre-dispersion by mechanical stirring with the pre-dispersion time being 0.5-1 hour; carrying out pre-dispersion again on pre-dispersed materials by a colloid mill, adjusting the dispersing effect by adjusting the fineness of the colloid mill, and when the penetration is proper, carrying out filling. The lubricating grease provided by the invention has the advantages that due to selection of a thickening agent with high-temperature performance and the base oil with high-temperature performance and addition of a solid lubricating agent with good high-temperature performance as the anti-wear reagent at extreme pressure, the lubricating grease has excellent high-temperature performance, anti-wear performance at extreme pressure and oxidation stability and obtains better technical effects. The high-temperature lubricating grease composition provided by the invention can be applied to lubrication and protection of high-temperature mechanical equipment in the industries of ceramic, metallurgy and machining and the like.

Description

technical field

[0001] The invention belongs to the technical field of lubricating grease, and in particular relates to a high-temperature lubricating grease composition and a preparation process. The lubricating grease has excellent high-temperature resistance, extreme-pressure anti-wear performance and oxidation stability, and can meet the requirements of ceramics, metallurgy, and mechanical processing. Lubrication and protection of high-temperature mechanical equipment in other industries. Background technique

[0002] With the continuous improvement of the level of industrialization, the operating temperature requirements of many lubricating parts are getting higher and higher, and higher requirements are also put forward for the high temperature resistance of lubricating grease. Most commonly used lubricating grease will soften, melt or volatilize at high temperature, thus losing its lubricating effect, resulting in machine wear, increased noise, and seizure, making it ...
