Problems solved by technology

[0006] At present, there are few reports in the literature that ε-polylysine is used in metalworking fluids, mainly because the formula system of metalworking fluids is more complicated. The addition of ε-polylysine needs to meet not only good biological stability, but also Lubrication, cooling, emulsion stability and corrosion resistance required for on-site processing

Abstract

The invention provides a composite fungicide and metal cutting fluid with the same and a preparation method of the composite fungicide. The composite fungicide comprises 1,2-benzisothiazole-3-ketone, epsilon-polylysine and water-soluble organic amino. In the composite fungicide provided by the invention, the three components, namely the 1,2-benzisothiazole-3-ketone, the epsilon-polylysine and the water-soluble organic amino are synergistic, so that the sterilization effect of the composite fungicide is improved; and the metal cutting fluid with the composite fungicide is good in sterilization effect, remarkable in biological stability, high in security and wide in application prospect, meets on-site process requirements such as lubrication, cooling, emulsion stability and corrosion resistance, and meets ideas of green chemicals.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and relates to a compound fungicide, a metal cutting fluid containing it and a preparation method thereof. Background technique [0002] In recent years, more and more domestic and foreign companies have paid more and more attention to environmental protection. In addition to meeting the basic national environmental protection regulations, many companies with social corporate responsibilities have formulated high environmental protection, safety and health policies for suppliers and themselves. , as a chemical supplier with a sense of social responsibility, Quaker has always actively promoted the concept of green chemistry and green process media. At present, the most common fungicides added in China are phenolic compounds, formaldehyde-releasing compounds, boric acid amines, etc., but their use has been banned by developed countries in Europe and the United States. It is extremely urgent to find an...
