Abstract

The application discloses a water-treated polyhexamethylene guanidine hydrochloride sterilizing agent and a preparation method thereof. The water-treated polyhexamethylene guanidine hydrochloride sterilizing agent is prepared by weighing and uniformly mixing guanidine hydrochloride, hexamethylene diamine, hexamethylenediamine, polyethylene glycol, water, methylbenzene, a polymerization inhibitor, sulphonic acid, maleic anhydride, N-t-butyloxycarboryl-1,6-diamino hexane, a dispersing agent, ferric sulfate, methacrylic acid, dodecyl dimethyl benzyl ammonium chloride and methyl acrylate according to parts by weight. The water-treated polyhexamethylene guanidine hydrochloride sterilizing agent is 100% soluble in water, has no volatility, can be completely neutralized with soaps, and has no pollution to environment; the integral of an acute skin irritancy test is 0, and the water-treated polyhexamethylene guanidine hydrochloride sterilizing agent is colorless, non-poisonous, odorless and tasteless, and has no corrosion to metal, rubber and plastic; the sterilizing rate to escherichia coli, staphylococcus aureus, candida albicans, neisseria gonorrhoeae, penicillium, aspergillus, saprophytic bacteria and salmonella is 100%, when the water-treated polyhexamethylene guanidine hydrochloride sterilizing agent is placed at 50-60 DEG C for a month, the sterilizing rate is 98-100%, when the water-treated polyhexamethylene guanidine hydrochloride sterilizing agent is placed at 40-50 DEG C for half a year, the sterilizing rate is 97.5-99.5%, and when the water-treated polyhexamethylene guanidine hydrochloride sterilizing agent is placed at the room temperature for 1-2 years, the sterilizing rate is 95-99%.

Description

technical field [0001] The application belongs to the field of environmental protection reagent technology, and in particular relates to a non-toxic polyhexamethyleneguanidine hydrochloride 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, ...
