Embodiment 1

[0014] 10 parts of double quaternary ammonium salt, 20 parts of polyoxysuccinic acid, 5 parts of defoamer, 10 parts of sandan oil, 30 parts of deionized water.

[0015] Wherein, the double quaternary ammonium salt is generated by the reaction of a long-chain tertiary amine and an alkyl halide, and the long-chain tertiary amine is reacted for 15 hours at a temperature of 50 degrees by a long-chain aliphatic amine, formaldehyde and formic acid, and 50% NaOH is added while it is hot. , adjust the PH value>10, add water to dilute, take the upper layer oil, and use anhydrous Na 2 SO 4 Dry to obtain long-chain tertiary amine; mix long-chain tertiary amine and haloalkane, add a certain amount of organic solvent, stir to obtain double quaternary ammonium salt.

Embodiment 2

[0017] 25 parts of double quaternary ammonium salt, 30 parts of polyoxysuccinic acid, 15 parts of defoamer, 20 parts of sandan oil, 55 parts of deionized water.

[0018] The double quaternary ammonium salt is generated by the reaction of a long-chain tertiary amine and an alkyl halide, and the long-chain tertiary amine is reacted for 6 hours at a temperature of 150 degrees by a long-chain aliphatic amine, formaldehyde and formic acid, and 50% NaOH is added while hot to adjust PH value>10, add water to dilute, take the upper layer oil, and use anhydrous Na 2 SO 4 Dry to obtain long-chain tertiary amine; mix long-chain tertiary amine and haloalkane, add a certain amount of organic solvent, stir to obtain double quaternary ammonium salt.

Embodiment 3

[0020] 18 parts of double quaternary ammonium salt, 25 parts of polyoxysuccinic acid, 10 parts of defoamer, 15 parts of sandan oil, 43 parts of deionized water.

[0021] The double quaternary ammonium salt is generated by the reaction of a long-chain tertiary amine and an alkyl halide, and the long-chain tertiary amine is reacted for 11 hours at a temperature of 100 degrees by a long-chain aliphatic amine, formaldehyde and formic acid, and 50% NaOH is added while hot to adjust PH value>10, add water to dilute, take the upper layer oil, and use anhydrous Na 2 SO 4 Dry to obtain long-chain tertiary amine; mix long-chain tertiary amine and haloalkane, add a certain amount of organic solvent, stir to obtain double quaternary ammonium salt.

Abstract

The invention discloses a quaternary ammonium salt bactericide. The quaternary ammonium salt bactericide mainly comprises 10-25 parts of bis-quaternary ammonium salt, 20-30 parts of polyoxy succinic acid, 5-15 parts of defoaming agents, 10-20 parts of starcide BK and 30-55 parts of deionized water. The quaternary ammonium salt bactericide has the advantages that the quaternary ammonium salt bactericide is a compound bactericide, the bactericidal performance of the quaternary ammonium salt bactericide is superior to the sum of effects of bactericidal properties of various individual bactericides, foaming of the bis-quaternary ammonium salt during use can be effectively prevented by the added defoaming agents and added dispersing agents, the bactericidal effectiveness can be improved under the condition of high degree of mineralization, and adsorption loss can be prevented; various compositions cooperatively work with one another, the efficacy is complementary, and the excellent quaternary ammonium salt bactericide can be provided for treating water.

Description

technical field [0001] The invention relates to a fungicide, in particular to a quaternary ammonium salt fungicide. Background technique [0002] The mechanism of action of quaternary ammonium salt fungicides is mainly that cations adsorb negatively charged bacteria through electrostatic force, hydrogen bond force, and hydrophobic binding between surfactant molecules and protein molecules, and gather on the cell wall, resulting in room resistance effect , leading to bacterial growth inhibition and death; at the same time, its hydrophobic alkyl group can also interact with the hydrophilic group of bacteria to change the permeability of the membrane, and then lyse, destroy the cell structure, and cause cell dissolution and death. This type of fungicide has the characteristics of high efficiency, low toxicity, not easily affected by pH changes, easy to use, strong peeling effect on the mucus layer, stable chemical properties, good dispersion and corrosion inhibition, but it is ...
