The invention relates to the field of adsorption materials, in particular to a formaldehyde adsorption material. The formaldehyde adsorption material is prepared from, by weight, 100 parts of activated carbon, 10-30 parts of calcium carbonate, 20-60 parts of ethanol, 5-25 parts of medical stones, 20-40 parts of sepiolite, 15-35 parts of glycine, 1-20 parts of perlite, 1-5 parts of sodium nitrate, 6-10 parts of ammonium bicarbonate, 2-6 parts of titanium dioxide, 3-7 parts of methylcellulose, 13-17 parts of ferric phosphate, 5-25 parts of magnesium chloride and 12-18 parts of talcum powder. According to the formaldehyde adsorption material, the formaldehyde removal rate reaches up to 98% to 99.8%; the formaldehyde adsorption material is high in wear resistance, long in service life, capable of being reused, green, environmentally friendly, high in adsorption and wide in adsorption range; after the formaldehyde adsorption material is taken to be put into a closed space with the formaldehyde content ranging from 400 micrograms per cubic meter to 500 micrograms per cubic meter for 40 h to 48 h, the formaldehyde concentration ranges from 1 microgram per cubic meter to 8 micrograms per cubic meter; the formaldehyde adsorption material is simple in preparation method, low in cost, high in operability and capable of being widely produced and continuously replacing existing materials.
