Effervescent disinfection tablet and preparation method thereof

Abstract

The invention provides a unitary chlorine dioxide effervescent disinfection tablet, prepared from the following components with total percentage of 100% in the terms of a main agent in percentage by weight: 10-40% of sodium chlorite as the main agent, 20-40% of sodium bisulphate as a solid acid, 3-5% of sodium bicarbonate as an effervescent agent, 5-15% of sodium chloride as a forming agent, 5-11% of sodium dichloro isocyanurate as an assistant, 5-15% of magnesium sulphate as a stabilizing agent and 1-4% of polyvinylpyrrolidone as a film forming agent. The invention also provides a preparation method of the unitary chlorine dioxide effervescent disinfection tablet, comprising the procedures of material taking in ratio, film packaging, raw material drying, raw material stirring and mixing, tablet forming, detecting and packaging. The effervescent disinfection tablet provided by the invention is the unitary chlorine dioxide tablet according to the technical scheme of the invention, is a disinfection preparation with the advantages of high chlorine dioxide content, stable property and convenience for transportation and use and with chlorine dioxide as the main agent, can realize the tablet production. The preparation method provided by the invention has the advantage of simple and safe preparation operation; and the potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to disinfectants, in particular to a monobasic chlorine dioxide effervescent disinfectant tablet and a preparation method thereof. Background technique [0002] Chlorine dioxide is the latest generation of high-efficiency, broad-spectrum, and safe fungicides and preservatives recognized internationally. It is the most ideal substitute for chlorine preparations and has been widely used in developed countries in the world. Relevant organizations in the United States, Western Europe, Canada, Japan and other developed countries, such as the U.S. Environmental Protection Agency, Food and Drug Administration, and the U.S. Department of Agriculture, have approved and recommended chlorine dioxide for use in food, food processing, pharmaceuticals, hospitals, public places, etc. The World Health Organization (WTO) and the World Food Organization (FAO) have also listed chlorine dioxide as an A1-level safe and efficient disinfectant for disin...

AI Technical Summary

Problems solved by technology

However, because chlorine dioxide is unstable, flammable and explosive, most of the existing powders or tablets are made into binary forms, that is, the agents A and B are separately made into tablets, that is, the generative agent and the activator Separated and then mixed when used, there are disadvantages such as inconvenient use, transportation, and storage; or although it is made into a unitary powder or tablet, it separates the generator and the activator by adding a large amount of auxiliary agents. Monobasic chlorine dioxide powder or tablet not only greatly reduces the disinfection efficiency and effect due to the existence of a large number of additives, but also has a safety hazard of flash explosion during processing
