Abstract

The invention discloses a water treatment tertiary aminating resin bactericide and a preparation method thereof. The water treatment tertiary aminating resin bactericide can be prepared by matching and weighing benzene, micrococcus chlorinus, dimethylamine, hydrochloric acid, water, ethanol, a polymerization inhibitor, alkali, isopropanol, chlorotetradecane, a dispersing agent, chloroacetic acid, bisphenol-A, benzotriazole and PBTCA (phosphono butane-1,2,4-tricarboxylicacid) in parts by weight, uniformly mixing the raw materials and carrying out vacuum drying; and the water treatment tertiary aminating resin bactericide has a sterilizing rate of 98 to 100 percent on escherichia coli, staphylococcus aureus, canidia albicans, gonococcus, penicillium, aspergillus, saprophytic bacteria and salmonella, has carrier content of 1 to 1.08mmol/g, has a corrosion rate of 0.0001 to 0.0021mm/a for tin brass, has a scale inhibition rate of 96 to 98 percent , has the sterilizing rate of 97.95 to 99.95 percent after being placed for one month at a temperature of 50 to 60 DEG C, has the sterilizing rate of 97.9 to 99.9 percent after being placed for half a year at a temperature of 40 to 50 DEG C, and has a sterilizing rate of 95 to 99 percent after being placed for 1 to 2 years at the room temperature.

Description

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