Problems solved by technology
Commonly used air disinfection methods include ozone, ultraviolet rays and chemical disinfectants. Due to equipment, places and other reasons, the scope of use of ozone and ultraviolet disinfection is limited. The most widely used is chemical disinfectants. The chemical disinfectants currently used are basically strong oxidants. , such as formaldehyde, glutaraldehyde, peracetic acid and chlorine-containing preparations, etc., are highly irritating and corrosive, and the disinfection of chemical reagents is contact sterilization. In order to avoid pollution to the crowd, protective measures must be taken when using , or to evacuate the crowd, and a long period of ventilation is required after disinfection before personnel can enter

Abstract
The invention relates to an air sanitizer. Silver ion colloid, cationic surfactant, addition agent and stabilizing agent in recipe quantity are put in a vessel and are mixed uniformly after being added with water to obtain the air sanitizer. Components with disinfection function in the air sanitizer comprise silver ion and quaternary ammonium salt cationic surfactants. The silver ion has sterilization function. The quaternary ammonium salt cationic surfactants are provided with positive charges, amino and hydroxyl groups on a molecular chain of which show prominent chemical absorption property. Compounds of the kind can change the permeability of bacteria membrane. And matched with the silver ion, the compounds can enhance the sterilization function of the silver ion and improve the sterilization efficiency. The prepared air sanitizer has the advantages of nontoxic property, colorlessness, tastelessness, no corrosion, no dying and no bleaching. No special protection is required before the air sanitizer is used. The air sanitizer can be directly sprayed in space to be sterilized. After the sterilization, no clearness (such as ventilation, etc.) is required. People can enter the space. The air sanitizer can be used conveniently and is worth being widely used.
Description
technical field [0001] The invention relates to a disinfectant, in particular to an air disinfectant containing silver and a preparation method thereof. Background technique [0002] Germs spread through two routes: fecal-oral and airborne. Air disinfection can effectively block the way of airborne diseases. Commonly used air disinfection methods include ozone, ultraviolet rays and chemical disinfectants. Due to equipment, places and other reasons, the scope of use of ozone and ultraviolet disinfection is limited. The most widely used is chemical disinfectants. The chemical disinfectants currently used are basically strong oxidants. , such as formaldehyde, glutaraldehyde, peracetic acid and chlorine-containing preparations, etc., are highly irritating and corrosive, and the disinfection of chemical reagents is contact sterilization. In order to avoid pollution to the crowd, protective measures must be taken when using , or evacuate the crowd, and after disinfection, a long...
