Abstract

The invention provides an organic molybdenum lubricant composition which is characterized by being prepared from the following components in parts by weight: 100 parts of aleutric acid; 50-100 parts of polyethylene glycol; 15-20 parts of ammonium phosphomolybdate; 8-10 parts of monoethanolamine and 5-8 parts of phosphorus pentoxide. The organic molybdenum lubricant composition prepared by the invention is an extreme pressure and antiwear additive containing Mo-P-S-N, has excellent antifriction performance and is also a good surfactant. A trace lubricant containing the organic molybdenum lubricant composition is prepared from the following components in percentage by weight: 30 to 40 percent of the organic molybdenum lubricant composition; 30-40% of octyldodecyl myristate; 5-10% of castor oil polymaleate; 5-10% of sodium sulfonated castor oil and balance of deionized water. The micro lubricant prepared by the invention can meet the requirements of lubrication and cooling, extreme pressure and wear resistance and rust prevention in metal processing; and more than 90% of the lubricant can be saved when used with a micro lubricating device.

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...
