Abstract

The invention is applicable to the field of air processing, and provides a formaldehyde-removal nano compound and a preparation method thereof. The method comprises the steps of preparing nano aerogel from photocatalyst-composite nano titanium dioxide, ultra-absorptive graphene, nano negative-ion tourmaline and cyclodextrin-cladding biological polyphenol through a supercritical carbon dioxide technology, extracting biological polyphenol from plants such as aloe and natural lauraceae, and preparing the formaldehyde-removal nano compound through a polymer polymerization method. The formaldehyde-removal nano compound has the functions of removing formaldehyde and adsorbing PM2.5 for a long time; moreover, the cost is low, and convenience in daily use can be realized.

Description

technical field [0001] The invention belongs to the field of air treatment, and in particular relates to a formaldehyde-removing nanometer mixture and a preparation method thereof. Background technique [0002] Due to air pollution, home decoration, car decoration, etc., people's health is eroded by more and more toxic and harmful gases and tiny particles. For example, after home decoration, harmful gases such as formaldehyde and benzene will remain indoors, or be directly inhaled into the human body , or these substances are adsorbed on PM2.5 particles and enter the human body through the capillaries of the lungs, which is more harmful than pure PM2.5 or pure formaldehyde. [0003] At present, people are constantly devoting themselves to the development of products that adsorb formaldehyde (including organic gases such as benzene), decompose formaldehyde, and remove formaldehyde. These application methods can effectively remove formaldehyde and other harmful gases to a cer...
