Abstract

The invention discloses an air purification material, which is prepared by the following method: (1) uniformly mixing a high polymer and an organic solvent to prepare a spinning solution, and dispersing the adsorption material in a volatile solvent to prepare a spray solution; (2), carry out high-voltage electrospinning and high-voltage electrostatic spraying to spinning liquid and spray solution respectively, receive together, after the solvent volatilizes, obtain the electrospinning spray nano-composite material that contains adsorption material; (3), obtained Composite materials and non-woven fabrics are hot rolled and combined on a hot rolling mill. In the present invention, nanofibers and activated carbon materials are combined to prepare electrospinning spray composite nanomaterials, which are composited with non-woven fabrics, not only have good air filtering functions, but also have good functions of adsorbing toxic and harmful gases, and can be widely used It is used in the field of air purification, such as air purifier filter elements, air conditioning filter elements, automotive interior materials, etc.

Description

technical field [0001] The invention relates to the field of materials, in particular to an air purification material. Background technique [0002] With the rapid development of modern industry, environmental problems are becoming more and more serious. Dust, vehicle exhaust, industrial waste gas, and toxic gases released from decoration materials have seriously endangered human health. [0003] At present, the main pollutants in the air are generally solid particles and harmful gases. Inhalable particulate matter has become the main pollutant in the urban weather environment. PM2.5 refers to particulate matter with a particle size less than or equal to 2.5 μm, also known as particulate matter that can enter the lungs. Its diameter is less than 1 / 20 of the thickness of human hair, and it contains a large amount of toxic and harmful substances, and it has a long residence time in the weather and a long transportation distance, so it has a greater impact on human health. ...
