Gel for slowly releasing chlorine dioxide and preparation method thereof

Abstract

The invention discloses a gel for slowly releasing chlorine dioxide. The gel comprises the following components in parts by weight: 3-6 parts of maltodextrin, 3-7 parts of cellulose hydroxypropyl methyl ether, 7-9 parts of magnesium sodium silicate and 2-5 parts of hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer. The invention also discloses a method for preparing the gel for slowly releasing chlorine dioxide. The method comprises the following steps: crushing, screening and uniformly mixing the components in the gel to obtain a mixture A; uniformly mixing sodium chlorite, solid organic acid, a stabilizer and a pH buffer agent to obtain a mixture B; performing vacuum mixing on the mixture A and the mixture B according to a weight ratio of 1: 4 to obtain a mixture C; and adding water into the obtained mixture C, and stirring into the gel; wherein the ratio of the mixture C to the water is 1: 9. The gel for slowly releasing chlorine dioxide disclosed by the invention contains gel, so that chlorine dioxide gas can be slowly released, and the gel is convenient to use and simple to prepare.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, in particular to a chlorine dioxide slow-release gel and a preparation method thereof. Background technique [0002] Chlorine dioxide is a yellow-green to orange-yellow gas that is easily soluble in water and does not react with water. It is listed as Class A1 disinfectant is the only one in disinfection technology that has received this certification. Chlorine dioxide has a good killing and inhibiting effect on hepatitis A, hepatitis B, typhoid fever, polio and HIV. Different from other chlorine preparations in the disinfection process, chlorine dioxide does not chlorinate with organic matter, does not produce three-cause (teratogenic, carcinogenic, mutagenic) and other toxic substances, and has no drug resistance. When the concentration is lower than 500ppm, its impact on the human body can be ignored. When the concentration is below 100ppm, it will not have any impact on the human body...

AI Technical Summary

Problems solved by technology

[0003] Existing chlorine dioxide disinfection products are divided into liquid type and solid type in terms of form; they are divided into two-component type, single-component type, etc. in terms of composition. Clothes, protective glasses, protective gloves, etc. Dissolve chlorine dioxide in water, then dilute it, and then spray it with a sprayer or a sprayer on the back of the bottle. This method of use will cause the liquid to wet the surface of the object, and the use is limited.

People are getting deeper and deeper into the concept of disinfection in daily life. Therefore, the research on chlorine dioxide sustained-release gel has become a hot spot. At present, there are many preparation methods for chlorine dioxide gel, but the common problems are complicated production process and low production efficiency. Problems such as high cost or short sustained-release time of gel lead to unsatisfactory actual use effect
