Foam type sterilizing, disinfecting and air purifying agent as well as preparation method and application thereof

Abstract

The invention belongs to the field of disinfectants, the invention discloses a foam type sterilizing, disinfecting and air purifying agent as well as a preparation method and application thereof. Theproduct is mainly prepared from the following components in percentage by weight: 0.10-0.40% of peroxyacetic acid, 0.15%-0.60% of hydrogen peroxide, 0.05%-0.10% of a quaternary ammonium salt type cationic surfactant, 0.05%-0.10% of benzethonium chloride, 0.10%-0.20% of alkyl glycoside, 0.10%-0.20% of a stabilizer, 0.20%-0.60% of glycerol and 97.80%-99.25% of water. The product has stable performance, wherein the retention time of the formed sterilization disinfectant foam in the environment is long and the sterilization and disinfection action time is long. The product is low in cost, has a good air purifying effect, is non-toxic, pollution-free and residue-free, has a broad-spectrum sterilizing effect, is applied to prevention and control of the novel coronavirus, can effectively kill thenovel coronavirus and cut off a virus transmission path, and can also effectively kill escherichia coli, staphylococcus aureus, pseudomonas aeruginosa, bacterial spores and other viruses and microorganisms.

Description

technical field [0001] The invention belongs to the field of disinfectants, and in particular relates to a foam-type sterilizing and air purifying agent and its preparation method and application. Background technique [0002] Since the beginning of 2020, there has been an outbreak of pneumonia caused by a new type of coronavirus in China. The new type of coronavirus is mainly transmitted through the direct transmission of droplets produced by patients and exhaled breath, or the deposition of droplets on the surface of objects through contact with infection. There is also the possibility of aerosol transmission through the mixing of droplets to form aerosols in the air. Droplets are greatly affected by environmental conditions such as humidity and climate, and have strong mobility. With the end of the Spring Festival and the resumption of work of enterprises and institutions, hospitals, shopping malls, airports, stations, schools and other crowded areas may have a higher con...

Problems solved by technology

[0003] At present, the commonly used methods for the prevention and control of new coronaviruses are sterilization and disinfection. Commonly used disinfectants include peracetic acid, sodium hypochlorite, chlorine dioxide, hydrogen peroxide, etc., but a single disinfectant such as sodium hypochlorite is unstable and needs to be prepared and used immediately. It is easy to decompose in the environment, and a large amount of use will pollute the environment. Peracetic acid is also unstable and needs to be prepared and used immediately. It is easy to decompose in the environment. single

In order to improve the sterilization and disinfection effect, the Chinese patent with the publication number CN 108902145A has reported a kind of bactericidal composition and its preparation and application. Escherichia coli, Listeria, Salmonella, Pseudomonas aeruginosa, Saccharomyces and S-type cholera bacteria can also effectively kill microorganisms such as small cocci and lactic acid bacteria, but the content of peracetic acid, hydrogen peroxide and potassium hydrogen persulfate is relatively high. High cost of use

The Chinese patent with publication number CN109006861A reports a kind of atomized disinfectant with chlorine dioxide and hydrogen peroxide as the main components, but its preparation adopts an atomization device, the process is complicated, the content of hydrogen peroxide and chlorine dioxide is relatively high, and it is inconvenient to use

The Chinese patent with notification number CN102038722B reports a composition for preventing new influenza A (H1N1) virus infection comprising ginkgo extract, an air filter coated with the composition and an air purifier comprising the air filter, but The preparation process of its main components is complicated, the cost is high, and it is difficult to use on a large scale

[0004] In summary, the bactericidal disinfectants in the prior art still have technical problems such as instability, complex preparation process, complex structure and limited use.
