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...
