The invention discloses a recyclable, purified and regenerated water-soluble cutting fluid, and a preparation method and application thereof, and belongs to the field of industrial media. The paint comprises the following components in parts by weight: 50-56 parts of naphthenic silicone oil, 5-7 parts of extreme pressure lubrication corrosion inhibitor, 10-12 parts of oily lubricating oil, 2-4 parts of antirust agent, 3-8 parts of alkaline retaining agent, 5-6 parts of span 80, 2-4 parts of fatty alcohol-polyoxyethylene ether, 4-6 parts of bactericide and 8-12 parts of deionized water. The pH of the cutting fluid is kept stable by adding excessive alkaline maintaining agent; the water-soluble low-molecular-weight chitosan reacts with pyridine to generate a chitosan derivative, so that the bacteriostatic effect on anaerobic microorganisms is enhanced; and finally, after the water-soluble cutting fluid is recycled, the metal powder is adsorbed through microelectrode reaction on the activated carbon, so that the interaction between the metal powder and the cutting fluid is reduced. The recyclable performance of the water-soluble cutting fluid is improved. |
