Problems solved by technology

[0003] However, chlorine dioxide gas is very active and unstable, and it is difficult to make compressed gas or concentrated solution. It needs to be prepared on site when used, and because chlorine dioxide gas is an explosive gas, it cannot be stored and transported, making the application range of chlorine dioxide severely restricted
[0004] At present, some research attempts to prepare chlorine dioxide solution or chlorine dioxide solid preparation with strong stability, but the stable chlorine dioxide solution needs to be activated before use, and there are still inconveniences during use and transportation
And existing chlorine dioxide solid preparation is mainly to absorb stable chlorine dioxide solution by specific adsorption carrier and mix with solid acid, stabilizer etc. Chlorine oxide gas release speed. In the preparation process of this kind of products, high-purity chlorine dioxide gas needs to be prepared in advance, but the high concentration of chlorine dioxide gas and strong oxidation characteristics are easy to corrode equipment during the preparation process, and the requirements for equipment are relatively high. High, easy to leak, and the chlorine dioxide released by this product is low in active ingredients, low in utilization rate, and serious in waste

Abstract

The invention discloses a slow-release carrier, a chlorine dioxide gel composition containing the slow-release carrier and application thereof The sustained-release carrier is prepared by adding a vinyl monomer solution containing a cross-linking agent and an initiator into a dispersion medium containing a separant and adopting a reversed-phase suspension method. The slow-release carrier has a three-dimensional network structure and a cross-linking gradient, has super-strong water absorption and water retention properties, and can be used as an excellent reaction place for various slow-release preparations. Moreover, after the slow-release carrier is loaded with a chlorine dioxide precursor, controllable slow release of chlorine dioxide can be realized, and the slow-release carrier has multiple application prospects of sterilization and disinfection, air purification, deodorization, fresh keeping and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a slow-release carrier, a gel composition containing the slow-release carrier and applications thereof. Background technique [0002] Chlorine dioxide (ClO 2 ) has a high-efficiency broad-spectrum bactericidal ability. It is a strong oxidizing agent that rapidly decomposes amino acids in bacteria, viruses, and proteins with its strong oxidizing properties, and can interact with many other reducing substances, various inorganic ions, and organic substances. Compared with chlorine gas, when chlorine dioxide is used for disinfection, only oxidation reaction occurs, no chlorination reaction occurs, no carcinogens such as chlorinated hydrocarbons are produced, and the oxidation capacity is 2.6 times that of chlorine gas. [0003] However, chlorine dioxide gas is very active and unstable, and it is difficult to make compressed gas or concentrated solution. It nee...
