Abstract

The invention discloses a water treatment disinfecting agent and a preparation method thereof. The water treatment disinfecting agent is prepared from a sodium hypochlorite aqueous solution and a , wherein the stabilizer is prepared from carboxymethyl cellulose sodium, 2-aminophenol, vitamin E, cyclodextrin and polyallylamine; and a mass ratio of sodium hypochlorite aqueous solution, carboxymethylcellulose sodium, 2-amino phenol, vitamin E, cyclodextrin and polyallylamine is (0.85 to 1.40): 1.00: (0.25 to 0.32): (0.05 to 0.07): (0.09 to 0.11): (0.20 to 0.22), and the active chlorine content of the sodium hypochlorite aqueous solution is 5.0 to 20.0 weight percent, and the water treatment disinfecting agent has the advantage of high stability.

Description

technical field [0001] The invention relates to a water treatment disinfectant and a preparation method thereof. Background technique [0002] Sodium hypochlorite solution is widely used in textile, printing and dyeing, paper making, industrial water treatment industry and daily life. Sodium hypochlorite solution itself has poor stability. The actual validity period of commercially available sodium hypochlorite solution is only 3 months, while the hygienic quality technical specifications for sodium hypochlorite disinfectants require its validity period to be more than 6 months, and users expect its validity period to reach 12 months. At home and abroad, the research and development of stable sodium hypochlorite solution is very important, and nearly 100 patents and papers on stable sodium hypochlorite solution formulations, preparation methods, and papers have been published. In the literature, sodium phosphate, sodium silicate and surfactants are generally used to improve...
