Problems solved by technology

Ordinary air purifiers cannot remove indoor harmful gases. The components of these gases are very complex. Cigarette smoke alone contains hundreds of gas components, plus aldehydes and benzenes emitted from decoration materials, and various pollution sources CO, SO 2 , NO x , NH 3 etc. are directly harmful to human health. To eliminate this hazard, functional air filter materials must be used
The disclosed patented technology fails to meet the comprehensive requirements of modern society for air filter materials that are multifunctional, long-lasting, reusable, and low in price
The applicant disclosed a filter material in Chinese Patent Application No. 2004100167006. Although it has good filter performance, there are still some deficiencies. Among them, the photocatalyst of nanoparticles cannot adhere to the filter material, and the durability It is still not ideal, and the filtration of some polar substances is still not perfect and needs to be improved

Abstract

A composite air filtering material for the indoor air conditioner is prepared from a non-woven polarized polypropene cloth as filtering layer and a composite oxide layer containing photocatalyst nanoparticles through needling. Said filtering layer is composed of a non-woven polarized polypropene cloth and the surface-treated magnetic nanoparticles attached to said non-woven cloth.

Description

technical field [0001] The invention relates to an air filter material and a preparation method thereof, in particular to an air filter composite material used for air conditioning, in particular to a material capable of effectively filtering particulate pollutants and gaseous pollutants in the air at the same time . Background technique [0002] With the increasing popularity of air conditioners and the wide application of a large number of new building decoration materials, indoor air pollution has further aggravated, and the problem of indoor air quality has become more prominent. A large number of research results have proved that indoor air quality is closely related to human health. In particular, gaseous pollutants such as volatile organic compounds (VOC) are the most harmful to the human body. However, due to the lack of efficient and practical purification methods for volatile organic compounds, no targeted measures have been taken in air-conditioning systems (inclu...
