Abstract

The invention discloses a preparation method of chlorine dioxide disinfection sustained-release gel, and belongs to the field of disinfection and sterilization and air purification. The preparation method of the chlorine dioxide disinfection sustained-release gel comprises the steps of preparing a gel prepolymer, adding gamma-glycidyl ether oxypropyl trimethoxy silane, tetraethoxysilane and sodiumdodecyl diphenyl ether disulfonate into a reaction kettle, stirring, adding a sulfuric acid solution into the reaction kettle, continuing stirring until hydrolysis, adding water, and uniformly stirring, carrying out reduced pressure distillation, and cooling to room temperature to prepare a gel prepolymer; preparing a sodium chlorite aqueous solution; and canning the gel prepolymer and a sodium chlorite aqueous solution according to a ratio of 1: 1, sealing, and standing to obtain the chlorine dioxide disinfection sustained-release gel. The gel prepared by the method disclosed by the invention is permanently non-liquefied and non-diluted, can keep a good gel state, and can have a shelf life of more than one year under a sealed lightproof room-temperature condition, and the storage loss ofchlorine dioxide is lower than 10%.

Description

technical field

[0001] The invention relates to a manufacturing method of chlorine dioxide disinfection slow-release gel, which belongs to the field of disinfection and air purification. Background technique

[0002] Chlorine dioxide is a broad-spectrum biocide, which has the advantages of good biocidal effect, wide applicable pH, low toxicity, and less halogenated hydrocarbons, which are potential carcinogens. It is widely used in drinking water treatment, industrial cooling water treatment, waste water, etc. Processing, air deodorization and sterilization, food preservation and preservation and other fields.

[0003] Chlorine dioxide is a yellow-green or orange-red gas at room temperature. Chlorine dioxide vapor resembles chlorine and nitric acid in appearance and taste, and has a suffocating odor. When cooled and over -40°C, it becomes a dark red or reddish brown liquid, and when the temperature is lower than -59°C, it becomes an orange-yellow solid. Chlorine dioxide is...
