Problems solved by technology

Although 3-isothiazolone compounds are very effective microbicides, they have the disadvantage of being unstable under certain conditions and in the absence of stabilizers, many 3-isothiazolones chemically degrade and lose their microbicidal efficacy

Abstract

The invention discloses a bactericide composition. The bactericide composition is characterized in that: the composition is an organic solution dispersion taking an organic solvent as a carrier or a water emulsion taking water as a carrier; and the composition comprises the following materials by weight percentage: 1 to 10 percent of 4,5-dichlor-octyl-3-isothiazole ketone, 1 to 20 percent of quaternary alkylphosphonium salt, 0.5 to 5 percent of dibutyl hydroxy toluene and 0.5 to 5 percent of dodecyl di(qae) glycin. The bactericide composition has the characteristics of low consumption and morestable and effective sterilizing effect.

Description

technical field [0001] The present invention relates to a fungicide composition, and more specifically to a fungicide containing 4,5-dichloro-n-octyl-3-isothiazolone for water treatment. Background technique [0002] In the petrochemical and electric power industries, fungicides are widely used in circulating cooling water systems, oil field sewage, and water injection systems to control the reproduction of microorganisms. One of the most effective and commonly used methods to control the growth of microorganisms in the cooling water system is to add fungicides to the cooling water. For decades, with the higher requirements for fungicides in terms of safety, environment and efficiency, various types of chlorine, bromine , amines, aldehydes, sulfur-containing, nitrogen-containing, and phosphine-containing fungicides, which greatly improve the efficiency of sterilization treatment. [0003] 3-Isothiazolone has been proven to be a safe, efficient, broad-spectrum and environmen...
