Abstract

The invention discloses a composite deodorizing filter material and a preparation method thereof. The composite deodorizing filter material comprises a porous carrier A loaded with an acidic compound,a porous carrier B loaded with a metal ion compound, and a porous carrier C loaded with an amino group-containing compound, wherein the mass ratio of the porous carrier A to the porous carrier B to the porous carrier C is 0.1-1: 0.1-2: 1-5. The porous carriers of the composite deodorizing filter material are respectively loaded with the acidic compound, the metal ion compound and the amino group-containing compound, thereby enhancing the chemical adsorption of a bad smell component by the filter material; and by rationally adjusting the ratio of the porous carrier A to the porous carrier B tothe porous carrier C, formaldehyde and common bad smell components in life are removed efficiently and simultaneously, so that the requirements of GB / T18801-2015 are satisfied, and the interference of bed smell on daily life is also reduced. The preparation process is simple and facilitates industrial production.

Description

technical field [0001] The invention relates to the technical field of indoor air purification, in particular to a composite deodorizing filter material and a preparation method thereof. Background technique [0002] In order to further improve the quality of life, people are not only satisfied with the removal of formaldehyde, VOCs and particulate matter in indoor air, but also put forward requirements for the removal of common odors in life. Common odor components in life include ammonia, trimethylamine, etc. Nitrogen compounds; sulfides such as hydrogen sulfide and methyl mercaptan; acidic substances such as acetic acid, etc. [0003] CN201711284823.1 discloses a preparation method of high-efficiency ammonia-removing activated carbon. The ammonia-removing activated carbon combines the method of microwave activation and the method of adding cobalt salt solution modification after acidizing the activated carbon, which greatly improves the The adsorption capacity of activat...
