Safe and slow release chlorine dioxide disinfectant and preparation method thereof

Abstract

The invention provides a safe and slow release chlorine dioxide disinfectant and relates to the technical field of daily disinfectants. The disinfectant is prepared from 50-60 parts by weight of a slow-release passivation stabilizer, 10-20 parts by weight of anhydrous sodium chlorite, 10-18 parts by weight of anhydrous sodium hydrogen sulfate, 7-12 parts by weight of anhydrous magnesium sulfate and 0-13 parts by weight of povidone K. The nano-attapulgite in the nanometer formula has the function of passivating a strong oxidizing substance, and the special multi-channel structure can effectively adsorb and control the moisture content so that the risk of ignition or explosion of a chlorine dioxide disinfectant product in the preparation and trial processes are significantly reduced or avoided and the slow release effect is obtained. The safe and slow release chlorine dioxide disinfectant has the ability to stably produce a low concentration of chlorine dioxide gas for six months and isespecially suitable for household disinfection and cleaning of daily necessities.

Description

technical field [0001] The invention relates to the technical field of daily-use disinfectants, in particular to a safe slow-release chlorine dioxide disinfectant suitable for daily household disinfection, sterilization and cleaning and a preparation method thereof. Background technique [0002] Disinfectants range from phenol to bleaching powder, from bleaching powder to sodium hypochlorite (such as 84 solution), and from Jie Er Mie (quaternary ammonium salts) to iodophor. Disinfectants have played a huge role in sterilization and ensuring people's healthy life. The problems of traditional disinfectants are: strong smell, corrosive, highly toxic and even carcinogenic substances. [0003] Since chlorine dioxide has no teratogenicity and carcinogenicity, it is a new type of disinfectant with high efficiency, wide range, low toxicity, fast speed, no corrosion, and no irritating odor. It has been listed as AI level by the United Nations Health Organization (currently the highes...

AI Technical Summary

Problems solved by technology

[0002] Disinfectants range from phenol to bleaching powder, from bleaching powder to sodium hypochlorite (such as 84 solution), and from Jie Er Mie (quaternary ammonium salts) to iodophor. Disinfectants have played a huge role in sterilization and ensuring people's healthy life. The problems of traditional disinfectants are: strong smell, corrosive, highly toxic and even carcinogenic substances

The disadvantage of this product is that on the one hand, the poor water solubility of the coating agent affects the use effect, and on the other hand, the melting of the coating agent will pollute the water quality

[0006] Chinese patent CN1415533A discloses a powdery chlorine dioxide disinfectant and its preparation method. The disinfectant prepared by the production method is one-package, which solves the problem of inconvenient use, but it uses highly reducing oxalic acid as a catalyst. Or react easily when hit and cause an accident

[0007] Chinese patent CN1439268A discloses a preparation method of a solid chlorine dioxide disinfectant. It uses organic polymers such as soluble polyvinyl alcohol to coat sodium chlorite. The biodegradability of the polymer is very poor, which does not meet the concept of eco-environmental protection

[0008] Chinese patent CN11406208A discloses a production method of solid chlorine dioxide in block form, which adopts organic raw material sodium dichloroisocyanurate or sodium trichloroisocyanurate as auxiliary chlorine dioxide generating agent, although it improves Chlorine gas generation, but because it can be decomposed into hypochlorous acid to produce a pungent smell of chlorine, it does not meet the concept of green products

In the existing technology, some scientists use polyvinyl alcohol, sodium polyacrylate, dextrin, sodium alginate and other organic polymer gels to stabilize chlorine dioxide, but the user needs to mix the two components A and B on site , it is not only inconvenient to use, but also has certain potential safety hazards. The materials used contain polymer materials that are not easy to biodegrade, which will cause secondary pollution to the environment.
