Solid stable chlorinedioxide antiseptics and preparation thereof

Abstract

A stable solid ClO2 disinfectant is prepared from sodium chlorite, solid acid, composite coating agent and composite trigger through compounding and passivating. Its advantages are high stability and safety, and long storage period.

Description

technical field [0001] The invention belongs to the technical field of antibacterial disinfectants and relates to an improved production method of chlorine dioxide disinfectants. Background technique [0002] Chlorine dioxide is an excellent high-efficiency, broad-spectrum, non-toxic, and non-residual disinfectant. Because it does not produce carcinogenic, suffocating, and mutagenic effects, it has been widely studied and used worldwide in recent years. [0003] At present, the process of producing solid chlorine dioxide release agent is mostly acidified sodium chlorite method. In view of the fact that sodium chlorite is very easy to react with solid acidifying agent and release chlorine dioxide immediately, the currently used chlorine dioxide disinfectant Most of the sodium chlorite and the solid acidifier are packaged separately, and this binary package is cumbersome to operate in use. [0004] Chinese patent CN1104610A discloses a production method of stable chlorine dio...

Problems solved by technology

[0003] At present, the process of producing solid chlorine dioxide release agent is mostly acidified sodium chlorite method. In view of the fact that sodium chlorite is very easy to react with solid acidifying agent and release chlorine dioxide immediately, the currently used chlorine dioxide disinfectant Most of them pack sodium chlorite and solid acidifier separately, and this kind of binary packaging is cumbersome to operate in use

[0004] Chinese patent CN1104610A discloses a production method of stable chlorine dioxide, melts white wax or stearic acid or beeswax as a coating agent, adds sodium chlorite to make microcapsule particles, and then mixes them with dry tartaric acid or oxalic acid particles Mixed bagging, the disadvantage of this production method is that the coating agent has poor water solubility. When the product is put into water for use, the coating agent melts and floats on the water surface, polluting the water quality

[0005] Chinese patent CN1238130A discloses a powdery chlorine dioxide disinfectant and its preparation method. The disinfectant prepared by the production method is a one-pack, and it uses alkali metal or alkaline earth metal chloride as a passivating agent to act as a coating drying agent. , so that sodium chlorite and solid acid do not react before use. The disadvantage is that a large amount of desiccant is used as a passivating agent in the production process of the disinfectant, resulting in high ineffective components, and because the passivating agent used absorbs water Strong, the storage time of the disinfectant is short, especially once the bag is opened, it will expire soon
