Problems solved by technology

[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 above problems such as large amount of lubricant used and serious pollution. At the same time, in order to make the micro-quantity lubricant used have relatively strong extreme pressure and anti-wear Sex and lubricity, excessive use of sulfur- and chlorine-containing additives that are not friendly to the environment, the use of minimal lubrication technology can solve the problem of large-scale use of cutting fluid and environmental pollution, but it is applied to difficult-to-machine metals such as titanium alloys, When processing tungsten steel alloy, stainless steel, etc., it is often difficult to achieve the required lubrication effect with the existing minimal quantity lubrication technology

Abstract

The invention provides an organic molybdenum lubricating oil composition, which is characterized in that, it is prepared by comprising eleostearic acid, ammonium phosphomolybdate, triethanolamine, octyldodecanol, and phosphorus pentasulfide, and the weight parts of the components are The number ratio is: eleostearic acid 100; octyldodecanol 50-80; ammonium phosphomolybdate 12-15; triethanolamine 8-10; phosphorus pentasulfide 3-5. The organic molybdenum lubricating oil composition prepared by the invention is an extreme pressure anti-wear additive containing Mo-P-S-N, and has excellent anti-friction performance. The present invention also provides an organic molybdenum trace lubricating oil containing the above organic molybdenum lubricating oil composition. Isooctyl ester 65-75%; polyricinoleate maleate 10-20%. The organic molybdenum trace lubricating oil prepared by the invention can meet the requirements of lubricating cooling, extreme pressure, anti-wear and rust prevention in metal processing; when used in conjunction with the trace lubrication device, the consumption of lubricant can be saved by more than 95%, and the effect of energy saving, emission reduction and environmental protection is achieved.
