Problems solved by technology

[0004] Whether it is prepared by chemical acid method or electrolysis method, although it has a certain degree of convenience; yet it must first mix reagents or make chlorite (ClO) in use. 2 - ) solution activation, or must produce chlorine dioxide gas by electrolysis of saturated salt water, and this operation is cumbersome and inconvenient and cannot quickly obtain chlorine dioxide gas; and whether it is produced by chemical acid method or electrolysis method Chlorine gas, which will continue to be released into the air, and as time goes by, the concentration of chlorine dioxide will continue to decrease, and thus it will not be able to provide long-term storage for subsequent disinfection and sterilization operations

Abstract

The invention relates to the technical field of disinfection and sterilization products, in particular to slow-release chlorine dioxide solid gel as well as a preparation method and application thereof. The slow-release chlorine dioxide solid gel comprises a component A parent gel and a component B activated gel, and the component A parent gel is prepared from the following substances in parts byweight: 0.5-15 part of chlorine dioxide active component, 1-30 parts of modified mesoporous silica nano material, 1-10 parts of gel powder and the balance of water; the component B activated gel is prepared from the following substances in parts by weight: 1-20 parts of an activating agent, 0-8 parts of a slow release agent, 1-30 parts of gel powder and the balance of water, so that the real-timepurification treatment on the environment is realized, the sterilization and virus killing efficiency of chlorine dioxide is greatly improved, and 24-hour full-time protection is truly realized; spraying is not needed, and labor cost is saved; meanwhile, the key problems of instability and short storage life of the liquid chlorine dioxide are solved.

Description

technical field [0001] The invention relates to the technical field of disinfection and sterilization products, in particular to a slow-release chlorine dioxide solid gel and its preparation method and application. Background technique [0002] Chlorine dioxide, the molecular formula is ClO 2 , among them, the standard oxidation state of the chlorine atom is +4, which is one of the few compounds in nature that exist almost entirely as monomeric free atom groups. Chlorine dioxide is a yellow-green to orange-yellow gas at room temperature, and has a pungent odor similar to chlorine gas. It is an internationally recognized safe and non-toxic green disinfectant. Chlorine dioxide does not react with organic matter in water to form trihalomethanes. It has no carcinogenic, teratogenic, and mutagenic (three-cause) effects on higher animal cells, sperm and chromosomes, and its safety is classified as A1 by the World Health Organization. At the same time, chlorine dioxide has strong...
