Problems solved by technology

But in actual use, because the hydrogen peroxide stability of low concentration (3.0%~5.0%) is relatively poor, it is often that high concentration hydrogen peroxide is mixed and used now, brings a lot of inconvenience to the user

Embodiment 1

[0019] Example 1. Under stirring, 7.5 g of 40% hydrogen peroxide was added to 92. g of deionized water to obtain a hydrogen peroxide solution. Then, add 0.1 g of EDTA disodium salt under stirring, and then add 0.1 g of peracetic acid after the solid is dissolved, and continue to stir and mix evenly. Finally, 0.1 g of etidylic acid and 0.2 g of acrylic acid polymer emulsion were added successively under stirring, and the stirring was continued for half an hour to obtain 100 g of hydrogen peroxide disinfectant. Sampling for quality testing to obtain finished products.

Embodiment 2

[0020] Example 2. Under stirring, 7.5 g of 40% hydrogen peroxide was added to 92.05 g of deionized water to obtain a hydrogen peroxide solution. Then, add 0.1 g of EDTA disodium salt under stirring, and then add 0.05 g of peracetic acid after the solid is dissolved, and continue to stir and mix evenly. Finally, 0.1 g of etidylic acid and 0.2 g of acrylic acid polymer emulsion were added successively under stirring, and the stirring was continued for half an hour to obtain 100 g of hydrogen peroxide disinfectant. Sampling for quality inspection to obtain finished products.

Embodiment 3

[0021] Example 3. Under stirring, 7.5 g of 40% hydrogen peroxide was added to 92.08 g of deionized water to obtain a hydrogen peroxide solution. Then, add 0.1 g of EDTA disodium salt under stirring, and then add 0.02 g of peracetic acid after the solid is dissolved, and continue to stir and mix evenly. Finally, 0.1 g of etidylic acid and 0.2 g of acrylic acid polymer emulsion were added successively under stirring, and the stirring was continued for half an hour to obtain 100 g of hydrogen peroxide disinfectant. Sampling for quality inspection to obtain finished products.

Abstract

The hydrogen peroxide air sterilizing liquid consists of hydrogen peroxide 3.0-5.0 wt%, organic acid 0.01-0.10 wt%, EDTA disodium 0.05-0.20 wt%, metal ion complex 0.10-0.40 wt%, non-ionic polyhydroxylated polymer 0.10-0.50 wt%. It is prepared through dissolving EDTA disodium, metal ion complex and non-ionic polyhydroxylated polymer in deionized water, and adding hydrogen peroxide and organic acid via stirring to obtain the stable air sterilizing liquid. The air sterilizing liquid has pH value of 2.0-3.0, hydrogen peroxide reducing rate at 54 deg.c for 14 days of 2.21-2.22 %, mouse acute oral toxicity LD50 greater than 5,000 mg/Kg and mouse acute inhalation LC50 greater than 10,000 mg/cu m. It has high germ killing rate, and is sprayed into air for sterilizing.

Description

technical field [0001] The invention belongs to the field of sanitation and disinfection, and relates to a hydrogen peroxide air disinfectant. Background technique [0002] The invention relates to a hydrogen peroxide air disinfectant. Specifically, it is to use an electric aerosol sprayer or an aerosol can of compressed butane gas to spray hydrogen peroxide air disinfectant in the indoor air to kill the pathogenic microorganisms in the room to achieve the purpose of disinfection. [0003] As we all know, pathogenic microorganisms in the air can spread diseases and endanger human health, especially in heavily polluted environments, which can easily cause respiratory tract infections and wound infections. Therefore, a clean indoor air environment is very beneficial to people's health. At present, the chemical disinfectants suitable for aerosol spray are mainly peracetic acid and hydrogen peroxide. Peracetic acid has fast sterilization speed, good effect and no residue. Ho...
