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. To 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 percent 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 filter material and a preparation method thereof. The method obtains a nano-copper-zinc oxide PTFE fiber air filter material through four steps of preparing nano-copper, preparing nano-zinc oxide, mixing ingredients and manufacturing non-woven fabrics. Zinc PTFE fiber air filter material. Compared with the prior art, the present invention has the following advantages: the air filter material obtained by the present invention contains nano-metal copper and nano-zinc oxide, has a filtering effect and also has a bacteriostasis effect, and has a wide variety of antibacterial and high efficiency; The efficiency reaches 99.99%, good air permeability, high filtration wind speed, and strong chemical stability; it can be well matched with air purifiers or fresh air fans; the manufacturing process is simple, and it is easy to realize industrialization.

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...
