Problems solved by technology

[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

Embodiment Construction

[0016] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0017] A preparation method of nano copper-zinc oxide PTFE fiber air filter material, characterized in that the steps are as follows:

[0018] Step 1. Prepare nano-copper. Take polyvinylpyrrolidone and add it to the aqueous solution of hydrazine hydrate. After stirring and heating to raise the temperature, add the mixture of copper sulfate and ammonia water dropwise. Wash the filter cake with ethanol and acetone, and obtain nano-copper after vacuum drying for 20 hours; the volume percentage concentration of the hydrazine hydrate aqueous solution is 6.67%, the consumption of the hydrazine hydrate aqueous solution is...

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...
