Abstract

The invention discloses a dibromocyanoacetamide (C2H2ON2Br2) disinfection tablet and a preparation method thereof. The dibromocyanoacetamide disinfection tablet is prepared from the following raw materials in parts by weight: 50 parts of C2H2ON2Br2, 20 parts of sodium carbonate (Na2CO3), 8 parts of sodium benzoate and 22 parts of CMC (Carboxy Methylated Cellulose). The preparation method comprises the following steps of: adding weighed raw materials into a blending machine, blending for 1 hour at normal temperature, taking a sample so as to measure the content of effective bromine, stopping blending after the content of the effective bromine reaches 50+ / -5wt%, pressure-testing some finished products, placing in cold water and observing effervescence time, sending the blended raw materials to a tablet making room for making the tablet after the blended raw materials reach the standard, and packaging to obtain the finished product of the dibromocyanoacetamide disinfection tablet. The preparation method is simple in process; and the prepared dibromocyanoacetamide disinfection tablet is a novel efficient disinfection tablet following a chlorine disinfection tablet; and by utilizing the dibromocyanoacetamide disinfection tablet, the problems of pungent smell and corrosion to metal of the chlorine disinfection tablet are solved, and bleaching properties to fabrics are reduced.

Description

technical field [0001] The invention relates to a dibromocyanoacetamide disinfection tablet and a preparation method thereof. Background technique [0002] Chlorine-containing disinfectant refers to a disinfectant that dissolves in water to produce hypochlorous acid with microbicidal activity, and its active microbicidal ingredients are often represented by available chlorine. Hypochlorous acid has a small molecular weight, and it is easy to diffuse to the surface of the bacteria and penetrate the cell membrane into the bacteria, oxidizing the bacteria protein and causing the death of the bacteria. Chlorine-based disinfectants kill a wide range of microorganisms, including bacterial propagules, viruses, fungi, tubercle bacilli, and the most resistant bacterial spores. Such disinfectants include inorganic chlorine compounds (such as sodium hypochlorite, calcium hypochlorite, chlorinated trisodium phosphate), organic chlorine compounds (such as sodium dichloroisocyanurate, tr...
