Abstract

The invention belongs to the fields of medical science, hygiene and epidemic prevention technology, aseptic technology, bioengineering and disinfection and sterilization, and environmental protection,and particularly relates to a chlorine dioxide composite material, and a preparation method and an application thereof. The chlorine dioxide composite material sequentially comprises a composite functional layer, a moisturizing layer and an adsorption layer; the composite functional layer sequentially comprises a chitosan layer and a chlorine dioxide mixing layer, the chlorine dioxide mixing layer is connected with the moisturizing layer, and the chlorine dioxide mixing layer is composed of a chlorine dioxide system A and a system B. The preparation method of the chlorine dioxide composite material comprises the steps: S1, preparing the chitosan layer; S2, preparing the chlorine dioxide system A; S3, preparing the chlorine dioxide system B; S4, uniformly mixing the chlorine dioxide systemA and the system B; and S5, compositing multilayerd structure. The prepared chlorine dioxide composite material has a long shelf life, the generation duration of chlorine dioxide gas is longer, chlorine dioxide gas can be stably and safely released, and the chlorine dioxide composite material has the effects of sterilization, disinfection, hemostasis, wound healing time shortening and air purification, and has good medical, environmental protection and daily use prospects.

Description

technical field [0001] The invention belongs to the fields of medicine, sanitation and epidemic prevention technology, aseptic technology, bioengineering, disinfection and sterilization, and environmental protection technology, and specifically relates to a chlorine dioxide composite material and a preparation method and application thereof. Background technique [0002] Chlorine dioxide is extremely soluble in water, and its solubility in water is five times that of chlorine gas. In the disinfection process, chlorine dioxide is usually used in the form of aqueous solution for easy handling. Because chlorine dioxide is very active and unstable, it can be made into an unstable aqueous solution. It is sensitive to light and heat. It has a dissociation rate of about 2% to 10% per day at room temperature. It is not easy to store and transport, and due to dissociation and Volatilization affects the disinfection effect of chlorine dioxide aqueous solution. [0003] At present, w...

AI Technical Summary

Problems solved by technology

Because chlorine dioxide is very active and unstable, it can be made into an unstable aqueous solution. It is sensitive to light and heat. It has a dissociation rate of about 2% to 10% per day at room temperature. It is not easy to store and transport, and due to dissociation and Volatilization affects the disinfection effect of chlorine dioxide aqueous solution

[0003] At present, what is more commonly used is to pass chlorine dioxide into the stable absorption liquid, generally composed of sodium carbonate or sodium percarbonate and hydrogen peroxide (patent No.: CN100441499C, CN1235913C) or add sodium hydroxide to form an alkaline solution (patent No. : CN103101883B), chlorine dioxide exists in the form of chlorite, and the stability of chlorite solution itself is relatively poor, and needs to be activated during use; extremely inconvenient to use

[0004] The lack of chlorine dioxide gas cannot be obtained quickly, the chlorine dioxide gas is continuously released into the air and lost, and as time goes on, the concentration of chlorine dioxide will continue to decrease, and thus it will not be able to provide long-term storage for subsequent disinfection , the lack of sterilization operations; therefore, how to quickly obtain chlorine dioxide for disinfection and sterilization, and how to store chlorine dioxide gas for a long time, and conveniently use chlorine dioxide to carry out disinfection and sterilization in the daily life and medical environment are the current problems to be solved topic

[0005] At present, although the existing chlorine dioxide gel material (patent number: CN103565828A,) does not need to be activated, the shelf life after production is not long and the action time is limited.
