Description

technical field [0001] The invention belongs to the technical field of environment-friendly materials, in particular to a nano-composite formaldehyde-removing and environment-friendly new material and a preparation method thereof. Background technique [0002] Formaldehyde is one of the indoor air pollutants. It is highly toxic and irritating. It is extremely harmful to human health. It is one of the main carcinogenic and teratogenic chemical substances. Formaldehyde in life usually comes from decoration and decoration materials. , furniture and coatings, etc., especially wood-based panels and the adhesives used. These materials use phenolic and urea-formaldehyde resins containing formaldehyde in the production process, and formaldehyde will be released during use. For a long time, how to effectively remove formaldehyde in indoor air has become a current research focus, because it is closely related to people's quality of life and their health. [0003] At present, most of ...
