Abstract

The invention discloses micro-emulsion cutting fluid and a preparation technology thereof. The micro-emulsion cutting fluid is prepared from 35-50 parts of a liquid-phase carrier, 8-15 parts of base oil, additives which include 15-25 parts of an antirust agent, 10-20 parts of a lubricant, 5-8 parts of a non-ionic surface active agent and 0.1-0.2 part of nanometer anti-mildew bactericide and processing aids. The preparation technology of the micro-emulsion cutting fluid comprises the steps of preparing a water phase system, and dissolving water and the processing aids dissolved into a water phase; preparing an oil phase system, and mixing the base oil and the additives and the processing aids dissolved into an oil phase; preparing a micro-emulsion system, slowly adding the prepared water phase system into the oil phase system, and mixing the mixture to be uniform; performing standing, and obtaining the finished micro-emulsion cutting fluid. The micro-emulsion cutting fluid is good in heat transfer performance, good in lubricating performance, not likely to be mildewed or sedimented or layered, and capable of reducing environmental pollution; meanwhile, the preparation method is simple and convenient and low in cost, simplifies production procedures and saves the cost.

Description

technical field [0001] The invention relates to the field of metal processing, and specifically designs a microemulsion cutting fluid and a preparation process thereof. Background technique [0002] During the forming process of metal processing, boring, drilling, tapping, grinding, cutting and many other processes are required according to different requirements. During these processing processes, there must be a lubricating cooling medium, commonly known as "cutting fluid". [0003] Traditional cutting fluids include water-based cutting fluids and oil-based cutting fluids. Oil-based cutting fluid adopts oil-based materials with particularly good lubricity, suitable for difficult cutting, tapping, drilling, extrusion, processing, such as cutting oil, emulsified oil and other oily products. Such oily products consume a lot of oil resources, and the strong pungent smell seriously affects the physical and mental health of operators. Moreover, the viscous residue left by chemi...
