A kind of slow-release chlorine dioxide powder and preparation method thereof

Abstract

The invention discloses a slow-release chlorine dioxide powder and a preparation method thereof. According to the weight ratio, the formula of the chlorine dioxide powder mainly consists of 5-10% chlorine dioxide precursor, 5-10% activated agent, 30-40% chloride ion supplement, 3-5% slow-release agent, 5-10% activated carbon powder, 5-10% polyethylene powder, and 15-47% filler. The preparation method of the slow-release chlorine dioxide powder includes steps such as material preparation, drying, and mixing. The operation is simple and convenient. It can be used to remove formaldehyde, benzene series and other air purifiers in the air. It can be used in household environmental protection, health and epidemic prevention, etc. All fields have good application prospects, and have the functions of purifying air, killing bacteria in the air, preventing epidemic diseases and removing peculiar smell in the air, and have a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a slow-release chlorine dioxide powder and a preparation method thereof. Background technique [0002] Chlorine dioxide is a highly water-soluble oxidant, which can rapidly oxidize and decompose bacteria, viruses, amino acids in proteins and many reducing substances, and can also interact with various inorganic ions and organic substances without causing cancer, Teratogenic, mutagenic chloroform (CHCl 3 ) and other organic halogenated substances, which can usually be used to make products such as sterilization, bleaching, antistaling agents, oxidizing agents, deodorizing agents, biocides, antistaling agents, bleaching agents, etc. After the disinfection of drinking water, my country also promulgated the "National Standard Stable Chlorine Dioxide Solution of the People's Republic of China (GB / T20783-2006)" on June 1, 2006, and was officially approved by the Ministry of...

AI Technical Summary

Problems solved by technology

[0003] The boiling point of chlorine dioxide is 11°C, which is relatively low. In the actual production process, gaseous chlorine dioxide is active and unstable. When it is used, it often needs to be prepared on site, which makes the concentration difficult to control. Therefore, Practicality is poor, for this reason, people all focus on its stable performance to the research emphasis of chlorine dioxide product, for example: the chlorine dioxide product that existing patent literature has disclosed as disinfectant and antistaling agent use: as disinfectant Solid chlorine dioxide disinfectant used (CN03155220.X) and powder stabilized chlorine dioxide disinfectant and its preparation method (CN200710190952.4); production of solid stabilized chlorine dioxide disinfection fresh-keeping deodorant used as fresh-keeping agent method (CN97103874.0) and solid chlorine dioxide slow-release agent (CN200510045006.1), etc., are all effective in preparing stable chlorine dioxide products, but with the competition and continuous development of the industry, in order to improve chlorine dioxide The application prospect of product, the present invention arises at the historic moment
