Abstract

The invention discloses a unitary solid chlorine dioxide sustained-release generating agent and a preparation method thereof. The generating agent does not contain solid acid; potassium hydrogen persulfate composite salt is reacted with stable acidic chlorite in a solution system under the synergy of synergist to generate chlorine dioxide; the generating agent consists of the chlorite, the potassium hydrogen persulfate composite salt, the synergist, stabilizer, forming agent, dryer, adhesive and effervescing agent; and the preparation method comprises the following steps of: drying the chlorite and the potassium hydrogen persulfate composite salt respectively, mixing the dried chlorite, the dried potassium hydrogen persulfate composite salt and the other materials uniformly according to acertain proportion, and preparing the mixture into tablets of different specifications under certain environmental humidity and pressure. The composite tables dissolved to water can sustainedly release the chlorine dioxide gas and have the characteristics of long effect, sustained release, environment friendliness, safety and the like.

Description

technical field [0001] The invention relates to a chlorine dioxide solid slow-release technology, in particular to a chlorine dioxide solid slow-release agent and a preparation method thereof. Background technique [0002] Chlorine dioxide is recognized as having high-efficiency broad-spectrum bactericidal properties, and its bactericidal ability is 2.6 times that of chlorine, which can completely kill bacterial propagules, spores, fungi, viruses, etc. It has a strong killing effect on the previously popular SARS virus and the H1N1 virus in recent years. The World Health Organization (WHO) has confirmed that chlorine dioxide is completely non-toxic, and the United States, Japan and other countries have approved chlorine dioxide to be used in disinfection fields such as food industry, pharmaceutical industry, and drinking water industry. Currently reported chlorine dioxide monobasic powder or tablet, its purpose is to make the concentration of chlorine dioxide solution reach...
