Abstract

The invention provides an organic molybdenum grease composition, which is characterized in that it is prepared from lacgaric acid, ammonium phosphomolybdate, melamine, stearyl alcohol, isopropanolamine, and phosphorus pentasulfide. The ratio of parts by weight is: 100 lacgaric acid; 50-60 stearyl alcohol; 15-20 ammonium phosphomolybdate; 8-10 isopropanolamine; 3-5 melamine; 3-5 phosphorus pentasulfide. The present invention also provides an organic molybdenum high-temperature grease containing the above-mentioned organic molybdenum grease composition, which is characterized in that it is made of the following components in weight percentage: organic molybdenum grease composition 50-60%; Castor oil toate 30‑40%; molybdenum disulfide 5‑15%. The organic molybdenum grease composition prepared by the invention is an extreme-pressure anti-wear additive containing Mo-P-N-S, has excellent friction-reducing performance, and can ensure that the paste-like physical form of the grease is good. The organic molybdenum high-temperature lubricating grease prepared by the invention is applied to the lubrication of parts such as bearings and guide rails, and prolongs the service life of the bearings and guide rails.

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, and in particular relates to an organic molybdenum high-temperature lubricating grease and a preparation method thereof. Background technique [0002] The traditional grease processing technology is: add animal and vegetable oil or fatty acid to inorganic base (such as sodium hydroxide, calcium hydroxide, lithium hydroxide, aluminum hydroxide, barium hydroxide, etc.) to prepare metal soap as thickener or use organic or Inorganic thickener, which is thickened by adding mineral oil or synthetic oil, is mainly to store mineral oil or synthetic oil in the framework of thickener, and store it in the thickener under the action of motion pressure and temperature. The oil in the chemical agent escapes to act as a lubricant, and exhibits paste-like physical properties under normal temperature and pressure. Under some extreme conditions such as high temperature and high pressure, because the oi...
