Abstract

The invention discloses a multifunctional nano-composite environment-friendly new material for removing formaldehyde and peculiar smell. The environment-friendly new material comprises the following raw materials in parts by weight: an organic solvent, polyacrylic acid, imidazolidinone, aminopropanol ascorbyl phosphate, a high-boiling-point solvent, an initiator, nanoscale rutile, carbon nanotubes, silicate minerals, plant polyphenol, an amino acid mixed solution, glucose and a polymerization inhibitor. The preparation method of the new material comprises the following steps:: 1, preparing anintermediate, 2, carrying out a constant temperature reaction, 3, preparing a copolymer, and 4, stirring and blending the components. According to the invention, formaldehyde is removed by using a photocatalytic oxidation method, nanoscale rutile is subjected to photocatalysis to form a photocatalyst, and the photocatalyst has excellent air purification ability, especially formaldehyde absorptionability, and has the characteristics of environmental protection, no color and odor, excellent formaldehyde removal ability and the like.

Description

technical field [0001] The invention relates to the field of formaldehyde-removing materials, in particular to a multifunctional nano-composite formaldehyde-removing, odor-removing and environmentally friendly new material. 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, chemical adsorp...
