Abstract

The application discloses an imidazoline biguanide sulfate bactericide for water treatment and a preparation method of the bactericide. The preparation method comprises the following steps: according to parts by weight, weighing the following materials: thiourea dioxide, dodecyl trimethyl ammonium bromide, hydrogen peroxide, brominated 1-butyl-2,3-dimethylimidazole, water, dodecylguanidine acetate, a polymerization inhibitor, sodium metasilicate pentahydrate, sulfuric acid, hexadecyl dimethyl benzyl ammonium chloride, a dispersing agent, dioctadecyl dimethyl ammonium chloride, imidazoline, triethylene tetramine and ethanol, and uniformly mixing the weighed materials; the scale inhibiting ratio of the product is 70-90%, and sterilizing rate on escherichia coli, staphylococcus aureus, candida albicans, gonococcus, penicillium, aspergillus, saprophytic bacteria and salmonella is 97.9-99.9%; when the bactericide is kept at 50-60 DEG C for one month, the sterilizing rate is 97.5-99.5%, when the bactericide is kept at 40-50 DEG C for half an year, the sterilizing rate is 97-99%, and when the bactericide is kept at room temperature for 1-2 years, the sterilizing rate is 94-98%.

Description

technical field [0001] The application belongs to the field of environmental protection reagent technology, and in particular relates to a non-toxic imidazoline biguanide sulfate bactericide for water treatment with remarkable bactericidal effect and a preparation method thereof. Background technique [0002] Water treatment bactericide is also called bactericide and algicide, sludge stripper or anti-sludge agent. 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. Including oxidizing fungicides, such as chlorine, sodium hypochlorite, bleaching powder, ozone, chloramine, etc.; non-oxidizing fungicides, such as dodecyl dimethyl benzyl ammonium chloride, dodecyl dimethyl benzyl bromide Ammonium, dithiocyanomethane, etc.; heavy metal compounds, such as mercuric oxide, mercuric chloride, mercuric fluoride, etc.; slime fungicides, such as rosin amine, hydrogen pe...
