Abstract

The invention discloses extreme pressure lubricating grease and a preparation method thereof. The lubricating oil comprises the following raw materials in percentage by weight: 10-20% of soap powder, 1-3% of an anti-adhesion composition, 5-10% of boric acid, 1-3% of butyl oleate, 1-5% of composite hydroxide salt, 1-3% of 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate, 1.5-2.3% of a high-temperature-resistant additive, 1-3% of a polyacrylate-styrene copolymerized water-based emulsion, 1-5% of water, 0.5-1% of an extreme pressure agent, 0.5-1% of a pour point depressant and the balance of base oil, the invention relates to the technical field of lubricating grease. According to the extreme pressure lubricating grease and the preparation method thereof, the anti-adhesion effect of the lubricating grease can be improved on the basis of ensuring high temperature resistance, high pressure resistance and aging resistance of the lubricating grease, and the purpose of reducing the adhesion of the lubricating grease by adding an anti-adhesion composition and a high-carbon organic matter into the lubricating grease is well achieved; the lubricating grease is prevented from being unevenly adhered to a smeared mechanical structure in a large area, the compression resistance and the high temperature resistance of the lubricating grease are guaranteed, and the aging time and the service life of the lubricating grease are prolonged.

Description

technical field [0001] The invention relates to the technical field of grease, in particular to an extreme pressure grease and a preparation method thereof. Background technique [0002] Grease refers to a thick grease-like semi-solid that is used in the friction part of machinery to lubricate and seal. Also used on metal surfaces to fill voids and prevent rust. It is mainly made of mineral oil (or synthetic lubricating oil) and thickening agent. Metal soaps are also used in potassium, barium, lead, manganese and other metal soaps. The thickeners of non-soap-based greases are made of graphite, carbon black, asbestos, and synthetic ones (such as polyurea-based, bentonite). According to the application, they can be divided into general-purpose greases and special-purpose greases. The former is used for general mechanical parts. The latter are used in tractors, railway locomotives, marine machinery, oil drilling machinery, valves, etc. The main quality indicators are droppin...
