Energy-saving and environment-friendly micro-emulsion cutting fluid

Abstract

The invention discloses an energy-saving and environment-friendly micro-emulsion cutting fluid, and belongs to the field of metal cutting lubricants. The micro-emulsion cutting fluid consists of the following components: 15 to 25 percent of mineral oil, 3 to 10 percent of extreme pressure anti-wear agent, 7 to 10 percent of mixed alcohol amine, 0.2 to 0.5 percent of non-ferrous metal antirust agent, 4 to 6 percent of boric acid, 8 to 12 percent of anionic surfactant, 5 to 12 percent of sulfonate antirust agent, 1 to 5 percent of alcohol type coupling agent, 4 to 6 percent of nonionic surfactant I, 5 to 7 percent of nonionic surfactant II, 0.5 to 1.5 percent of emulsification regulator, 0.5 to 2 percent of bactericide, 0.1 to 0.3 percent of anti-foaming agent, and the balance of deionized water. The micro-emulsion cutting fluid has the advantages that emulsified particles are small and stable, the oil-containing ratio is greatly reduced, the anti-rust property of the micro-emulsion cutting fluid is superior to that of emulsified cutting fluid, and the micro-emulsion cutting fluid does not contain chlorine and nitrite; and after the waste fluid is subjected to simple oil separation treatment, residues in the water can be biodegraded, so that environment friendliness and energy conservation are facilitated.

Description

technical field

[0001] The invention relates to an energy-saving and environment-friendly microemulsion cutting fluid, which belongs to the field of metal cutting lubricants. Background technique

[0002] Stainless steel cutting fluids generally include water-based cutting fluids and oil-based cutting fluids. Oil-based cutting fluids have poor heat dissipation and troublesome cleaning; water-based cutting fluids include emulsified and fully synthetic types. Water-based cutting fluids have little impact on the environment and stable performance, but poor lubricity; in addition, rust removal in most cutting fluids The ingredients contain nitrite, which is a high carcinogen, and the emulsified cutting fluid has a short service life. Contents of the invention

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide an energy-saving and environment-friendly microemulsion cutting fluid that does not contain harmful substances such as...
