Air filter screen, preparation method and application thereof

Abstract

The embodiment of the invention relates to an air filter screen, a filter material attached antibacterial composition. The antibacterial composition is prepared from the following components by mass:1-15 parts of an antibacterial agent, 1-10 parts of a porous carrier, 0.1-5 parts of a stabilizer, 0.5-5 parts of a surfactant and 1-15 parts of an adhesive; wherein the antibacterial composition is added into the filter material according to an addition amount of 2-70g/m<2>. The air filter screen has the effects of resisting bacteria, mildew and viruses and reducing peculiar smell.

Description

technical field [0001] The invention relates to the field of air purifiers, in particular to an air filter and its preparation method and application. Background technique [0002] In order to prevent the spread of diseases, researchers generally use droplets and air as the medium, and use filter materials to prevent the spread of microorganisms. However, the bacteria and viruses enriched on the surface of the filter material can still maintain their activity. Simple filtration interception is not enough to suppress the microbial contamination of the filter material during reuse and disposal. It is necessary to develop a filter material that can quickly inactivate microorganisms. [0003] Adding features to prevent spore germination and microbial survival in air filtration units will help reduce the risk of disease and allergic reactions. The antimicrobial functional layer also prolongs the service life of the filter unit. Microbial activity shortens the life cycle of the ...
