Problems solved by technology

[0004] Most commercial fresh air systems and air purifiers use methods such as 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

Abstract

The invention discloses a filtering net composite material for an air purifier. The filtering net composite material is characterized by containing the following raw materials in parts by weight: 5-10 parts of nano-copper, 5-10 parts of nano-zinc oxide, 10-15 parts of nanometer titania aqueous dispersion with the concentration of 40%, 60-80 parts of acetone, 2-5 parts of an epoxy resin, 1-5 parts of poly-1,4-diphenylbutadiyne and 30-40 parts of activated carbon fibers. The filtering net composite material for the air purifier, disclosed by the invention, contains metal nano-copper, nano-zinc oxide and nanometer titania and has the effects of filtering, inhibiting and killing bacteria and removing formaldehyde. The composite material is excellent in PM2.5 filtering effect, high in formaldehyde removal rate, wide in types of inhibited and killed bacteria, long in service life, safe and environment-friendly. Meanwhile, the preparation method provided by the invention is low in material cost, readily available in raw materials and simple and clear in process and has high practical value and excellent application prospects.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a filter net composite material for an air purifier 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. Formaldehyde is recognized as a highly toxic substance, and its toxicity to the human body is highly toxic. In recent years, the research on indoor air formaldehyde pollution caused by room decoration and its harm to human body has become a hot spot of social concern. Formaldehyde is extremely harmful to human health. If the indoor air formaldehyde content i...
