Preparation method of high-temperature lubricating grease

Abstract

The invention relates to the technical field of lubricating oil, and discloses high-temperature lubricating grease and a preparation method thereof. The lubricating grease is prepared from the following raw materials in parts by weight: 50-70 parts of base oil, 20-30 parts of fatty acid calcium, 10-14 parts of magnesium phosphate, 5-7 parts of liquid paraffin, 5-7 parts of turkey red oil, 16-20 parts of aluminum isopropoxide, 10-12 parts of stearic acid, 8-10 parts of silicone oil, 4-8 parts of nanometer silica powder, 1-3 parts of an antioxidant, 10-18 parts of alkyl phenolic resin, 15-20 parts of phosphate, 10-18 parts of acrylic resin, 18-25 parts of pentaerythritol, 12-18 parts of polyurea, 5-9 parts of trisodium phosphate, 16-24 parts of polyethylene glycol, 4-11 parts of graphite fibers, 3-9 parts of nano molybdenum powder, 5-11 parts of nano cerium oxide powder, 2-8 parts of nano calcium borate, 1-4 parts of sodium antimony gluconate and 1-3 parts of bismuth potassium citrate. According to the preparation method for the high-temperature lubricating grease, the scientific and appropriate components and the reasonable usage amount are combined, so that the prepared lubricatinggrease has the advantages of being stable in quality, excellent in extreme pressure antiwear property, corrosion resistance, oxidation stability and high-temperature resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a high-temperature lubricating grease. Background technique [0002] The English name of lubricating grease is a thick grease-like semi-solid, which is used for the friction part of the machine to lubricate and seal. It is also used on the metal surface to fill the gap and prevent rust. It is mainly composed of mineral oil or synthetic lubricating oil and thickened The vast majority of grease is used for lubrication, called anti-friction grease, anti-friction grease mainly reduces mechanical friction, prevents mechanical wear, and also protects against metal corrosion, and seals Dustproof function, some greases are mainly used to prevent metal from rusting or corrosion, called protective greases, such as industrial Vaseline, etc. There are a few greases specially used for sealing, called sealing greases, such as thread grease, most of the greases are It is a semi-solid s...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a preparation method of high-temperature lubricating grease, which has the advantages of corrosion resistance and high temperature resistance, and solves the problems of ordinary lithium-based lubricating grease in terms of mechanical stability, colloidal stability and oxidation stability. It is not very obvious, and the lubrication effect in high temperature environment will be greatly reduced, and the effect that people need cannot be achieved.
