Abstract

The invention provides wear-resistant and high temperature-resistant lubricating grease and a preparation method thereof. The wear-resistant and high temperature-resistant lubricating grease is prepared from the following raw materials in part by weight: 40-80 parts of poly alpha-olefin, 10-30 parts of liquid paraffin, 10-30 parts of Turkey red oil, 10-40 parts of attapulgite, 10-30 parts of nanographene, 10-20 parts of a poly-urea thickener, 10-25 parts of 2,5-dibutyl hydroquinone, 9-15 parts of diphenylamine, 7-19 parts of 2,4-methyl phenyl diisocyanate, 6-13 parts of triethanolamine, 8-14parts of tricresyl phosphate, 12-18 parts of 12-oxystearic acid, 10-16 parts of phenyl-beta-naphthylamine, 5-12 parts of ethylene carbonate and 10-25 parts of normal butanol. The lubricating grease provided by the invention has higher high temperature, extreme pressure wear resistance and corrosion resistance, thereby having higher stability and long service life; and the preparation process is simple, excellent in performance and suitable for universal industrial production and application.

Description

technical field [0001] The invention relates to a lubricating grease, in particular to an anti-wear and high-temperature resistant lubricating grease and a preparation method thereof. Background technique [0002] Lubricating grease is used in the friction part of the machine to lubricate and seal. It is also used on metal surfaces to fill gaps and prevent rust. It is mainly prepared from mineral oil (or synthetic lubricating oil) and thickener. Grease Widely used in industrial fields. [0003] However, the lubricating grease in the prior art has poor lubrication stability and poor high temperature resistance; although it can be applied to occasions with various requirements for temperature, load carrying capacity and lubricating performance, it has higher requirements for temperature and load carrying capacity In some occasions, lubricating grease with more stable performance and product performance is required; at the same time, the existing lubricating grease production ...
