Abstract

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.

Description

technical field [0001] The invention relates to the field of adsorption materials, in particular to a formaldehyde adsorption material. Background technique [0002] Formaldehyde purification adsorbent refers to the adsorption material that is mainly used to absorb formaldehyde in household life. It generally has the following characteristics: 1) It has a large specific surface area and strong adsorption capacity; 2) It has high adsorption performance for gases and can quickly Adsorption; 3) Environmental protection, no pollution, low manufacturing cost. [0003] Formaldehyde purification adsorbent can effectively adsorb formaldehyde, benzene, xylene and other harmful substances released due to home decoration. The main component is active silicon, which is an amorphous substance. It is made of natural quartz sand and refined through special processing technology. It has a large specific surface area and a rich pore structure that matches the size of indoor harmful gas mole...
