Technical Field

The invention relates to the technical field of disinfection powder, in particular to air disinfection powder capable of controllably releasing chlorine dioxide and a preparation method thereof.

Background

Chlorine dioxide is a gas from yellow green to orange yellow, and is a safe and nontoxic green disinfectant recognized internationally. A large number of foreign experimental studies show that chlorine dioxide is safe and freeThe toxic disinfectant has no 'three-cause' effect (carcinogenesis, teratogenesis and mutagenesis), and does not produce chlorination reaction with organic matter in the course of disinfection to produce 'three-cause' organic disinfectantChlorine Article of manufactureOr other toxic species. However, because chlorine dioxide has a very strong oxidizing power, it should be avoided at high concentrations (>500ppm) was used. When the concentration is lower than 500ppm, the influence on the human body can be ignored, and when the concentration is lower than 100ppm, the influence on the human body can not be generated, including the physiological and biochemical influences. It has no sensitization effect on skin. In fact, chlorine dioxide is conventionally used at concentrations well below 500ppm, typically only around a few tens of ppm. Therefore, chlorine dioxide is also internationally recognized as a safe, non-toxic, green disinfectant. The invention provides a controllable-release chlorine dioxide air disinfectant powder and a preparation method thereof, which are used for solving the existing problems.
