The invention discloses attapulgite particles for purifying air and a preparation method thereof and relates to the technical field of processing of attapulgite. The attapulgite particles are prepared from the following raw materials: 130 to 150 parts of attapulgite, 60 to 70 parts of solid waste fiber pulp, 10 to 13 parts of diatomite, 5 to 10 parts of nano bentonite, 5 to 10 parts of modified sepiolite, 3 to 5 parts of sodium carbonate, 3 to 5 parts of butadiene-styrene emulsion, 3 to 5 parts of camphor tree bark, 3 to 5 parts of ammonium molybdate, 3 to 5 parts of folium artemisiae argyi, 3 to 5 parts of ammonium chloride, 1 to 3 parts of amino resin, 1 to 3 parts of Carbomer, 1 to 3 parts of methyl citrate, 1 to 3 parts of xanthan gum, 1 to 3 parts of acrylic acid, 1 to 3 parts of octyl acrylate, 1 to 3 parts of potassium persulfate, 1 to 3 parts of tourmaline powder, 3 to 5 parts of a pore forming agent, 3 to 5 parts of an auxiliary agent and 180 to 200 parts of water. The attapulgite particles disclosed by the invention are used as an ammonia-removing adsorption material for purifying air and have a good adsorption effect.
