Embodiment 1

[0064] Example 1 A slow-release chlorine dioxide solid toilet sterilization and deodorant (A:B=50g:30g)

[0065] Formula: Component A: 20% sodium chlorate, 15% sodium sulfite, 42% silica gel powder, 8% diatomaceous earth, 15% polyvinyl alcohol; component B: 5% sodium bisulfate, 5% sodium dihydrogen phosphate, Purified water 90%.

[0066] Preparation method: crush sodium chlorate and sodium sulfite through a 60-mesh sieve, and set aside. Dry sodium chlorate at 50-60°C for 8 hours; dry sodium sulfite and silica gel powder at 50-60°C for 4 hours. Dry the polyvinyl alcohol at a temperature of 60~70°C for 4 hours. According to the formula ratio, sodium chlorate, sodium sulfite, and silica gel powder are evenly mixed, and loaded into the lower layer of the double-layer slow-release device; diatomaceous earth and polyvinyl alcohol are evenly mixed, and then loaded into the upper layer of the double-layer slow-release device. According to the formula ratio, sodium bisulfate and sod...

[0070] Formula: Component A: Potassium Chlorate 20%, Potassium Sulfite 20%, Polyacrylic Resin 38%, Sodium Silicate 7%, Polyvinyl Alcohol 15%; Component B: Potassium Hydrogen Sulfate 5%, Potassium Dihydrogen Phosphate 5% %, purified water 90%.

[0071] Preparation method: crush potassium chlorate and potassium sulfite through a 60-mesh sieve, and set aside. Potassium chlorate is dried at a temperature of 50-60°C for 8 hours; potassium sulfite and polyacrylic acid resin are dried at a temperature of 50-60°C for 4 hours. Dry the polyvinyl alcohol at a temperature of 60~70°C for 4 hours. According to the formula ratio, potassium chlorate, potassium sulfite and polyacrylic acid resin are evenly mixed, and loaded into the lower layer of the double-layer slow-release device; sodium silicate and polyvinyl alcohol are evenly mixed, and then loaded into the upper layer of the double-layer slow-rel...

Embodiment 3

[0072] Example 3 A slow-release chlorine dioxide solid refrigerator deodorant (A:B=20g:10g)

[0073] Formula: Component A: Sodium Chlorate 15%, Sodium Sulfite 15%, Hydroxymethyl Cellulose 54%, Diatomaceous Earth 6%, Polyvinyl Alcohol 10%; Component B: Sodium Bisulfate 5%, Sodium Dihydrogen Phosphate 5%, purified water 90%.

[0074] Preparation method: crush sodium chlorate and sodium sulfite through a 60-mesh sieve, and set aside. Dry sodium chlorate at 50-60°C for 8 hours; dry sodium sulfite and hydroxymethyl cellulose at 50-60°C for 4 hours. Dry the polyvinyl alcohol at a temperature of 60~70°C for 4 hours. According to the formula ratio, sodium chlorate, sodium sulfite and hydroxymethyl cellulose are uniformly mixed, and loaded into the lower layer of the double-layer slow-release device; diatomaceous earth and polyvinyl alcohol are evenly mixed, and then loaded into the upper layer of the double-layer slow-release device. According to the formula ratio, sodium bisulfate...

Abstract

The invention relates to a slow release type chlorine dioxide solid disinfectant and a preparation method thereof. The slow release type chlorine dioxide solid disinfectant is composed of a component A, a component B and a double-layer slow release device. The component A comprises chlorine dioxide parent, a reducing agent, a filling agent, a stabilizer and a slow release carrier. The component B comprises acid solution. The component A is placed in the double-layer slow release device, and the component B is independently packaged. The preparation method is simple, and the slow release type chlorine dioxide solid disinfectant is suitable for industrial large-scale production, convenient to use, easy to store and long in guarantee period and has good application prospects in the fields such as home furnishing, environmental protection and health defence. The slow release type chlorine dioxide solid disinfectant can be used for deodorization and disinfection of a refrigerator, a toilet, a shoe cabinet, a storage room and the inside of a vehicle and the like.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a slow-release chlorine dioxide solid disinfectant and a preparation method thereof. Background technique [0002] Chlorine dioxide is a highly water-soluble oxidant, its oxidizing ability is 2.6 times that of chlorine gas, it can rapidly oxidize and decompose amino acids in bacteria, viruses, proteins and many reducing substances, and can also combine with various inorganic ions and organic substances It has an effect and will not produce carcinogenic, teratogenic, mutagenic organic halogenated substances such as chloroform. It can usually be used in the production of sterilization, bleaching, preservatives, oxidants, deodorants, biocides, preservatives, bleaching agents and other products. Chlorine dioxide is currently internationally recognized as a safe and spectrum sterilizing, fresh-keeping and deodorizing agent. It is the most ideal substitute for chlorine preparat...
