Abstract

The invention relates to an adsorbing material for effectively adsorbing formaldehyde and other harmful substances in the air, belonging to the field of the adsorbing material for improving the air quality. The adsorbing material has the technical scheme that the material is characterized by comprising the raw materials based on the parts by weight: 10-20 parts of zeolite, 20-30 parts of sepiolite, 15-25 parts of diatomite, 10-15 parts of bentonite, 15-25% of active carbon and 6-12 parts of silicasol, wherein the silicasol is nanoscale silicon dioxide colloid water solution. The technical scheme also comprises the raw materials based on the parts by weight: 10-15 parts of higher molecular weight organic amine polymer with the molecular weight of 1800-50000, 5-10 parts of active carbon fiber and 10-20 parts of non-woven fabrics. The invention selects the substances with very strong adsorbing function and designs a set of formulation according to the different adsorption capacity and selectivity of the substances, so as to lead the substances to be matched with each other for adsorbing common indoor pollution gases such as formaldehyde, benzenes, hydrocarbons, other organic gas molecules larger than oxygen and nitrogen molecules in the air as well as virus bacterium and fine dust, thus purifying the indoor air, preventing decoration disease and improving the health level of residents.

Description

technical field [0001] The invention relates to an adsorption material for effectively adsorbing formaldehyde and other harmful substances in the air in the field of adsorption materials for improving air quality. Especially suitable for indoor air purification. Background technique [0002] After interior decoration, a large amount of harmful gases will be produced, such as formaldehyde, benzene, toluene, xylene and other harmful gases, and affected by the environment, there are also a large number of viral microorganisms and fine dust free in the air. At present, the main means to solve the above-mentioned harmful substances include: the first is a physical method using activated carbon and the like as adsorption materials. The principle of this method is to adsorb pollutants in the indoor environment, such as formaldehyde, on the material to achieve the purpose of removing pollutants. The price of activated carbon is not very expensive, ranging from a few yuan to tens o...
