Novel efficient germicide and algicide and preparation process thereof

Abstract

The invention discloses a novel efficient germicide and algicide and a preparation process thereof. The novel efficient germicide and algicide comprises the following raw materials in percentage by weight: 25-35% of dichloroether, 20-35% of tetramethylethylene diamine, 0.5-5% of dodecyl dimethyl tertiary amine, 0.1-2% of phase transfer agents, 0.1-0.5% of initiator and the balance of deionized water. The novel efficient germicide and algicide belongs to a non-oxidizing germicide and algicide, the germicide and algicide effect is good, and the novel efficient germicide and algicide has good dispersion, seepage and slime removal effects; foam is not produced when the novel efficient germicide and algicide is used, the effect of the novel efficient germicide and algicide lasts for a long period of time, the consumption of the novel efficient germicide and algicide is low, 6-10 ppm (parts per million) of the novel efficient germicide and algicide can have a good use effect in water, and the novel efficient germicide and algicide does not corrode equipment or pipelines and is safe and reliable to use, transport and store and environmentally friendly.

Description

technical field [0001] The invention relates to the field of water treatment chemicals, in particular to a novel high-efficiency bactericide and algicide and a preparation process thereof. Background technique [0002] Bactericides and algicides have oxidizing and non-oxidizing properties. At present, the commonly used oxidizing bactericides and algicides include compounds with oxidizing properties such as chlorine-containing compounds, peroxides, and bromine-containing compounds. These compounds generally have a strong biocidal effect on microorganisms in water, fast bactericidal and algae killing speeds, high broad-spectrum biocidal effects, and low treatment costs, but are greatly affected by organic matter, reducing substances and pH values ​​​​in water, and the effective time of the agent Short, large dosage, high frequency of dosing, and poor dispersion, penetration and stripping effects. Commonly used non-oxidative bactericidal algicides are isothiazolinones, quatern...

AI Technical Summary

Problems solved by technology

Isothiazolinones, aldehydes, and chlorophenols have better bactericidal performance, but poor algae killing and slime stripping performance, and aldehydes and chlorophenols are more toxic, which is not environmentally friendly; quaternary ammonium salts kill algae and slime stripping The performance is very good, but the dosage is large, and a large amount of foam is generated during use, causing the instrument indication to be distorted
