Problems solved by technology

Oxidative fungicides are widely used because of their low price, but they are easily affected and interfered by pH, organic matter, scale and corrosion inhibitors in circulating cooling water, which reduces the bactericidal effect, and long-term use, due to microbial resistance , will also affect the bactericidal effect; the treatment cost of non-oxidizing bactericides is higher than that of oxidizing bactericidal algicides, which is likely to cause environmental pollution, and after a single bactericide is used for a long time, organisms will develop drug resistance, antiseptic, and bactericidal less effective

Embodiment 1

[0035] A method for preparing a water treatment bactericide, comprising the following steps: weighing 1% octylisothiazolinone, 10% zinc pyrithione, 5% zinc oxide, 2-methyl-1,2-benzene 4% of isothiazol-3-one, with the balance being water, was sequentially added into the container, stirred at a stirring rate of 100 r / min, and stirred for more than 30 minutes to obtain a milky preservative.

Embodiment 2

[0037] A method for preparing a water treatment bactericide, comprising the following steps: weighing 1.5% of octylisothiazolinone, 8% of zinc pyrithione, 6% of zinc oxide, 2-methyl-1,2-benzene 3.5% of isothiazol-3-one, with the balance being water, was added to the container in sequence, stirred at a stirring rate of 100 r / min, and stirred for more than 30 minutes to obtain a milky preservative.

Embodiment 3

[0039] A method for preparing a water treatment bactericide, comprising the steps of: weighing 3% of octylisothiazolinone, 6% of zinc pyrithione, 7.5% of zinc oxide, 2-methyl-1,2-benzene Add 2.5% of isothiazol-3-one and water as the balance, and add them into the container one by one, stir at a stirring speed of 200 r / min, and stir for more than 30 minutes to obtain a milky preservative.

Abstract

The invention discloses a water treatment sterilization agent and a preparation method thereof, and belongs to the technical field of preservatives. The key points of the technical scheme are as follows: the sterilization agent comprises the following raw materials: octyl isothiazolinone, zinc pyrithione, a stabilizer, 2-methyl-1,2-benzisothiazol-3-one and water; the preparation method comprises the following steps: weighing the octyl isothiazolinone, the zinc pyrithione, the stabilizer, the 2-methyl-1,2-benzisothiazol-3-one, glutaraldehyde, bis[tetrakis(hydroxymethyl)phosphonium] sulfate, a cationic surfactant and water in percentage by weight, sequentially adding the weighed substances into a container, and stirring for 30 minutes or longer to obtain the emulsion preservative. The effects of improving the spectral sterilization performance of the sterilization agent and preventing microorganisms from generating drug resistance are achieved.

Description

technical field [0001] The invention relates to the field of preservatives, in particular to a water treatment bactericide and a preparation method thereof. Background technique [0002] Water treatment preservatives are a class of chemicals that can inhibit the growth of bacteria, algae and microorganisms in water to prevent the formation of microbial slime and cause harm to the system. Commonly used water treatment fungicides mainly include chlorine gas, sodium dichloroisocyanurate, trichloroisocyanuric acid, etc. Commonly used non-oxidizing fungicides mainly include quaternary ammonium salt organic compounds, quaternary phosphonium salt organic compounds, isothiazolinone and pentyl diol, etc. Oxidative fungicides are widely used because of their low price, but they are easily affected and interfered by pH, organic matter, scale and corrosion inhibitors in circulating cooling water, which reduces the bactericidal effect, and long-term use, due to microbial resistance , w...
