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

Embodiment 1

[0026] (1) Polarized preparation of non-polar materials:

[0027] First, the air is ionized under the action of a corona needle with a bias voltage of 3000v / cm to form ionized air, and then the melt-blown polypropylene non-woven fabric passes through the ionized air to form a permanent electric body.

[0028] (2) Preparation of a composite material oxide layer containing a photocatalyst of nanoparticles:

[0029] A needle-punched composite of intertwined polyester and polypropylene impregnated with TiO 2 In the mixture with water, run at a speed of 5 m / min, go through double-roll rolling, remove the water, and dry at a temperature of 85°C;

[0030] TiO 2 In a mixture with water, TiO 2 Concentration of 20% by weight, TiO 2 The dosage is 15% of the composite material, by weight;

[0031] (3) The materials in steps (1) and (2) are needled and compounded so that the fibers of the two layers are intertwined with each other. It can be integrated smoothly and evenly to obtain t...

Abstract

The invention discloses an air filter material and its preparation method. The material is composed by polarized PP non-fiber filter layer and optical catalyst complex oxide layer containing nanometer grains, and the optical catalyst is TiO2. The method of the invention is simple and quick. The cost is low, the performance is well. The invention can effectively block the grains and gas pollutants and can be reused through simple treatment. It can be widely utilized on house air conditioners.

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...
