A kind of controllable slow-release chlorine dioxide material and its one-step preparation method

Abstract

The invention provides a controllable extended-release chlorine dioxide material and a one-step preparation method thereof, and belongs to the technical field of long-acting bactericidal materials andpreparation. According to the adopted technical scheme, the controllable extended-release chlorine dioxide material is prepared from the following raw materials: porous particles, chlorite, a film-forming agent, chlorate chlorid and hydrogen peroxide, wherein the chlorite, the film-forming agent and the chlorate chlorid are loaded on the porous particles. The controllable extended-release chlorine dioxide material and the one-step preparation method thereof have the beneficial effects that chlorine dioxide of the controllable extended-release chlorine dioxide material is stable in release speed and low in release concentration, and the bactericidal effect is good; the release period is long, and the service life is long; in the using process, no particles fall off, secondary pollution ofchlorite dust is avoided, and thus the environment and human health is effectively ensured; and according to the preparation method, only one step is needed to prepare an impregnating solution, then impregnation, adsorption and drying are conducted, the step is concise and efficient, the cost is low, energy consumption is low, and industrialized and large-scale production is facilitated.

Description

technical field [0001] The invention relates to the technical field of long-acting bactericidal materials and their preparation, in particular to a controllable slow-release chlorine dioxide material and a one-step preparation method thereof. Background technique [0002] Chlorine dioxide has strong oxidizing properties and is widely used in the fields of sterilization, bleaching, deodorization, disinfection and fresh-keeping. It is harmless and has no secondary pollution to the environment. It is internationally recognized as a safe and non-toxic green disinfectant. However, its safety is under the premise of low concentration. When it is high concentration, it is harmful to organisms and even explosive. Dangerousness; How to make chlorine dioxide release continuously and at low concentrations is a technical issue that has been devoted to research in the fields of sterilization and freshness preservation. At present, the precursor of chlorine dioxide (chlorite) is usually ...
