Abstract

The invention relates to a special micro-lubricant for an oil-water-gas-phase micro-lubricating system. The lubricant is characterized by comprising an oiling agent A and water aqua B, wherein the oiling agent A is prepared from the following components in percentage by weight: 40-60% of polyricinoleate, 30-50% of low viscosity synthetic ester, 2-5% of phosphate and 2-5% of ethanolamine borate; the water aqua B is prepared from the following components in percentage by weight: 95-98% of water, 0.5-2% of molybdate, 0.5-2% of phosphate, 0.5-1% of lower alcohol and 0.01-0.05% of benzotriazole or derivatives. The special micro-lubricant for the oil-water-gas-phase micro-lubricating system, which is disclosed by the invention, is matched with a micro-lubricating device in use, so that the use level of a cutting liquid is saved by over 95%.

Description

technical field

[0001] The invention belongs to the technical field of lubrication, and relates to a special trace lubricant for an oil-water-air three-phase trace lubrication system and a preparation method thereof. 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. 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 has solved the above-mentioned problems such as large amount of lubricant usage and serious pollution. Lubrication technology has made a relatively large breakthrough and has been commercialized. However, although there has been some pro...
