▎ 摘  要

NOVELTY - Air purification material comprises first flexible adsorption layer, porous graphene-like adsorption layer, catalytic agent layer and second flexible adsorption layer. Both the first flexible adsorption layer and the second flexible adsorption layer are flexible carriers loaded with molecular sieves and copper sulfate. USE - The air purification material is useful in circulation systems, such as air conditioners, air conditioning fans and humidifiers for removing particulate matter 10 mu m and 2.5 mu m and formaldehydes. ADVANTAGE - The air purification material has 360 degrees flexibility, long service life, good sterilization, mildew removal and total volatile organic compounds removal effects, low maintenance cost and no space occupation, can be used in small spaces and produces low noise. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing flexible air purification material, which involves mixing isocyanate, citric acid, potassium persulfate, Bordeaux mixture, sodium chlorite, alumina, magnesium oxide, sodium hydroxide and water, evenly stirring the mixture, filtering out the paste-like catalytic agent through precipitation, applying the paste-like catalytic agent layer on the activated carbon fiber felt, drying, placing the porous graphene-like adsorption layer coated with the catalytic agent layer between the first flexible adsorption layer and the second flexible adsorption layer, and then edging the edges to obtain an air purification material.
