Abstract

The invention discloses a nano copper-zinc oxide PTFE fiber air filtration material and a preparation method thereof. According to the preparation method, the nano copper-zinc oxide PTFE fiber air filtration material is obtained through four steps of nano copper preparation, nano zinc oxide preparation, ingredient mixing and non-woven fabric manufacture. Compared with the prior art, the preparation method has the advantages that the air filtration material obtained by means of the method contains nano metal copper and nano zinc oxide, has the filtration effect and antibacterial effect and is capable of inhabiting and killing varieties of bacteria, high in efficiency, good in air permeability, high in air filtration speed and good in chemical stability and can be well matched with an air purifier or a novel fan, the filtration efficiency is up to 99.99%, a manufacturing process is simple, and industrialization is easily achieved.

Description

technical field [0001] The invention relates to the field of indoor air filter nets, in particular to a nanometer copper-zinc oxide PTFE fiber air filter material and a preparation method thereof. Background technique [0002] As the environment changes, indoor air pollution is becoming more and more serious. It not only contains some harmful gases and fine particles such as formaldehyde and toluene, but also contains a large number of bacteria and fungi, such as Neisseria meningitidis, Mycobacterium tuberculosis and Escherichia coli. , Staphylococcus aureus, etc., these bacteria will cause serious damage to the human body. [0003] At present, most commercial fresh air systems and air purifiers use ultraviolet light and plasma to sterilize the air. Due to the fluidity of the air, the sterilization effect of these methods is not very obvious, and it is easy to cause potential harm to the human body, and has no filtering effect. Therefore, it is of great significance to stud...
