Isothiazolinone type compound micro-emulsion type sterilization mildew preventive as well as preparation method and application thereof

Abstract

The embodiment of the invention relates to the field of industrial corrosion prevention and mildew prevention, particularly relates to an isothiazolinone type compound micro-emulsion type sterilization mildew preventive as well as a preparation method and application thereof and more particularly relates to a 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT) and 1,2-benzisothiazolin-3-one (BIT)compound micro-emulsion type sterilization mildew preventive as well as a preparation method and application thereof. The DCOIT and BIT compound micro-emulsion type sterilization mildew preventive provided by the embodiment of the invention is prepared from: DCOIT, BIT and auxiliary agents for a micro-emulsion preparation; the preparation method of the DCOIT and BIT compound micro-emulsion type sterilization mildew preventive comprises the following step: preparing the DCOIT, the BIT and the auxiliary agents for the micro-emulsion preparation into the DCOIT and BIT compound micro-emulsion typesterilization mildew preventive. The DCOIT and BIT compound micro-emulsion type sterilization mildew preventive provided by the embodiment of the invention is a stable, efficient and environment-friendly compound micro-emulsion type sterilization mildew preventive of slightly soluble fungicides including the DCOIT and the BIT, can be diluted randomly by water and is not separated out; respectiveadvantages of the DCOIT and the BIT in the aspects of sterilization, corrosion prevention and mildew prevention also can be sufficiently expressed; the DCOIT and BIT compound micro-emulsion type sterilization mildew preventive has high efficiency, low toxicity and high application value.

Description

technical field [0001] The present invention relates to the field of industrial anticorrosion and mildew prevention, in particular to an isothiazolinone compound microemulsion type bactericide and antifungal agent, its preparation method and application, more specifically to a 4,5-dichloro-2-n-octyl Di-4-isothiazolin-3-one (DCOIT) and 1,2-benzisothiazolin-3-one (BIT) compound microemulsion fungicide and antifungal agent, its preparation method and application. Background technique [0002] 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT), its structural formula is: [0003] [0004] DCOIT is an efficient and quick-acting broad-spectrum fungicide, anti-fungal agent, and anti-rust agent. It can be widely used in paints, coatings, plastics, leather, sewage, paper, wood, adhesives, inks and other fields. It can replace the highly toxic Compounds such as organic arsenic. The main active ingredient in the Sea-Nine 211 marine antifouling paint developed by Rohm and Haas is ...

AI Technical Summary

Problems solved by technology

The DCOIT and BIT compound microemulsion bactericidal and antifungal agent provided in the examples of the present invention simultaneously solve the insoluble problem of DCOIT and BIT, and the preparation is stable and uniform, with good chemical and physical stability; it can be arbitrarily diluted with water without precipitation , which solves the problem of poor stability of isothiazolinone fungicides at the used concentration; the active ingredients DCOIT and BIT in the preparation have high bactericidal activity, and can give full play to the respective advantages of the two in terms of bactericidal, anti-corrosion and anti-mildew, thereby reducing complex The dosage of microemulsion type bactericidal antifungal agent is used (to achieve the same bactericidal effect, the dosage of compound microemulsion type bactericidal antifungal agent is less), which reduces toxic and side effects; the cost of antiseptic and antimold is reduced, and the application value is high
