Abstract

The invention discloses semifluid lubricating grease and a preparation method thereof. The semifluid lubricating grease is prepared from the following raw materials in parts by weight: 40-50 parts of naphthenic oil, 15-25 parts of fluorine ester, 4-8 parts of glycol, 5-10 parts of polybutylene, 3-6 parts of coconut diethanolamide, 2-4 parts of isobutene triethoxy silane, 4-7 parts of Vaseline, 3-5 parts of glycerol ester of rosin, 2-3 parts of triazole fatty acid amine salt, 5-10 parts of chlorinated paraffin, 1-2 parts of butyl hydroxy anisd and 4.5-6.5 parts of dinonyl barium sulfonate. The lubricating grease disclosed by the invention has excellent extreme pressure antiwear property and proper adhesion so as to ensure extremely good lubricating property, and meanwhile has good pumpability, resistance to oxidation and rust protection and corrosion resistance. The lubricating grease can be used for replacing gear oil to be used in various high load positive gears and bevel gears at low- and medium-speeds and the like. The lubricating grease is simple in application process, convenient to add grease, workload-reducing, tank leakage-reducing and long in oil change period, and the maintenance workload of equipment and the consumption of the lubricating grease are reduced.

Description

Technical field [0001] The invention relates to a semi-fluid grease and a preparation method thereof, and belongs to the technical field of grease. Background technique [0002] Grease is made of mineral oil (or synthetic lubricating oil) and thickening agent. It is a thick grease-like semi-solid. It is used in the friction part of the machine to provide lubrication, reduce mechanical friction and prevent mechanical wear. It also plays a protective role to prevent metal corrosion and seals and prevents dust; it is also used on metal surfaces to fill gaps and prevent metal rust or corrosion. Among them, semi-fluid lubrication is a large category of grease specifications, which is generally suitable for replacing high-viscosity lubricating oil equipment, which can save energy, reduce leakage and extend service life. However, the semi-fluid grease currently on the market has the shortcomings of poor extreme pressure anti-wear and adhesion properties, resulting in unsatisfactory lub...
