Abstract

The application discloses a formaldehyde removal material and a preparation method and application thereof. The formaldehyde removal material is made from, by weight, 10-60 parts of plant polyphenols,10-60 parts of alumina and 10-80 parts of a silicate mineral. The application also discloses the preparation method of the formaldehyde removal material, and application of the formaldehyde removal material as a filter element material for air filters or in purifying air in furniture. The application is mainly intended to provide the plant polyphenol material for formaldehyde removal to solve thetechnical problem that existing activated carbon products for formaldehyde removal experience mildew and sourness after a period of time of use, and also solve the problem that the prior chemical preparations for formaldehyde removal are corrosive, have irritating odor, have unstable physical and chemical indexes at normal temperature and cause harm to human bodies during production.

Description

technical field [0001] This application relates to the field of new materials, in particular, to a formaldehyde-removing material and its preparation method and application. Background technique [0002] Formaldehyde, colorless, irritating to human eyes and nose. Excessive formaldehyde is almost an unavoidable problem after the renovation of new houses. Since formaldehyde is difficult to remove, the result will be a delay in the check-in time after the renovation of the new house, and even cause great harm to the health of the residents. Therefore, formaldehyde removal products are getting more and more attention from the general public. At present, the main methods of removing formaldehyde are adsorption method and chemical absorption method. [0003] Most of the adsorption methods use activated carbon as the adsorption carrier, because the moisture absorption capacity of activated carbon is stronger than the ability to absorb gas, and it is often in a state of high water...
