Abstract

The invention discloses slow-release immobilized chlorine dioxide particles and a preparation method of the particles. The method comprises the following steps that S1, a surfactant is added to an acid solution, natural zeolite particles are immersed into the acid solution, and then modified natural zeolite particles are obtained through solid-liquid separation; S2, the modified natural zeolite particles are soaked in a transition metal salt solution, and then through solid-liquid separation and calcination, load transition metal zeolite particles are obtained; S3, sodium chlorite powder, silica gel powder and diatomite are mixed according to a proportion, and a covering agent is obtained; S4, the covering agent and the load transition metal zeolite particles are mixed, put into a pelletizer and sprayed with a binding agent, and after covering, pelletizing and drying are conducted, the slow-release immobilized chlorine dioxide particles are obtained; S5, the slow-release immobilized chlorine dioxide particles are placed in a ventilation bag. The slow-release immobilized chlorine dioxide particles release chlorine dioxide gas slowly, the preservation and application period is long,and the particles have the functions such as sterilization and formaldehyde degradation.

Description

technical field

[0001] The invention relates to the field of preparation of air purifiers, in particular to a slow-release solid-carrying chlorine dioxide particle and a preparation method thereof. Background technique

[0002] Chlorine dioxide is a non-toxic, harmless and highly effective strong oxidizing bactericidal disinfectant, which has the functions of antisepsis, deodorization and preservation. It is non-pathogenic, non-teratogenic, and non-carcinogenic. It has been approved by the US Food and Drug Administration (FDA), the US Environmental Protection Agency (EPA) and the US Department of Agriculture (USDA) as early as the 1980s. It is the first class A1 disinfectant in the safe disinfection method. Under the same conditions, its sterilization and disinfection ability is 2.63 times that of chlorine gas, and it has the characteristics of wide sterilization range, good effect, short action time and low dosage.

[0003] The ability of chlorine dioxide to remove chemic...
