Abstract

The invention relates to the technical field of cutting fluid, in particular to high-quality micro-emulsified cutting fluid for metal machining. The high-quality micro-emulsified cutting fluid for metal machining comprises five steps of nano-carbon tube strong acid oxidation treatment, nano-carbon tube ball milling, preparation of oil-based mixed liquid, preparation of water-based mixed liquid andpreparation of the micro-emulsified cutting liquid. Compared with existing cutting fluid, a prepared MoS2 / CNTs nano-tubular structure is added to the water-based mixed liquid, high lubricity and relatively high thermal conductivity are used, and the lubricating performance and cooling performance of the micro-emulsified cutting fluid can be enhanced, even at a high temperature of 650-1200 DEG C,MoS2 does not lose lubricity when being carbonized, the condition that the service life of a tool is reduced due to high temperature in the metal cutting process or the effect of a cutting surface ofa workpiece is poor due to loss of lubricity at the high temperature can be effectively prevented; and in addition, the oil base of the chip liquid is a biodegradable base oil, various additives haveno harm to the environment, and the current demand of environmental protection is met.

Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to a high-quality microemulsion cutting fluid for metal processing. Background technique [0002] Cutting is the most important processing method in mechanical manufacturing. During the cutting process, it is necessary to add an appropriate amount of cutting fluid between the tool and the workpiece to perform various functions such as cooling, lubrication, rust prevention, and cleaning. Especially for cutting fluid used in metal cutting, its cooling performance and lubricating performance determine the service life of the tool and the cutting effect of the workpiece surface. [0003] The patent No. CN104479826B discloses a cutting fluid in the process of superhard material processing. The cutting fluid includes the following components: molybdenum disulfide, tartaric acid, chlorinated paraffin, oleic acid, sodium petroleum sulfonate, and transformer oil and / or soybean oil. ...
