Abstract

A kind of organic molybdenum lubricant composition provided by the present invention is characterized in that, it is prepared by comprising laccarnation acid, ammonium phosphomolybdate, polyethylene glycol, monoethanolamine, phosphorus pentoxide, the composition of The ratio of parts by weight is: Lacic acid 100; polyethylene glycol 50-100; ammonium phosphomolybdate 15-20; monoethanolamine 8-10; phosphorus pentoxide 5-8. The organic molybdenum lubricant composition prepared by the invention is an extreme pressure anti-wear additive containing Mo-P-S-N, has excellent friction-reducing performance, and is also a good surfactant. A micro-quantity lubricant containing an organic molybdenum lubricant composition, which is prepared from the following components in weight percent: organic molybdenum lubricant composition 30-40%; octyldodecyl myristate 30-40%; Polycastor oil maleate 5‑10%; Sodium castor oil sulfonate 5‑10%; Deionized water balance. The micro-quantity lubricant prepared by the invention can meet the lubricating cooling, extreme pressure anti-wear and anti-rust requirements of metal processing; when used with a micro-quantity lubrication device, the amount of lubricant used can be saved by more than 90%.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to an organic molybdenum lubricant composition trace lubricant and a preparation method. Background technique [0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators. . [0003] In order to solve these problems, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology solves the problems of large amount of lubricant used and serious pollution, but excessive use of sulfur and chlorine-containing additives that are not friendly to the environment , will have a certain impact on the environment. At the same t...
