The present invention discloses a modified formaldehyde decomposition material using shell powder as a carrier and a preparation method thereof. Imidazolidinone, zinc ricinoleate and negative ion powder, specifically including the following raw materials in parts by mass: 50-70 parts of modified shell powder, 10-20 parts of chitosan oligosaccharide, 5-15 parts of aminocyclodextrin, 2-imidazolidinone 5 to 10 parts, 4 to 8 parts of zinc ricinoleate, 15 to 25 parts of negative ion powder, and 100 parts of deionized water. The modified formaldehyde decomposing material of the invention has the functions of immobilization and long-lasting degradation of formaldehyde, nanometer copper sulfide/silver phosphate heterojunction is formed on the surface of the shell powder, and the photodegradation performance of the modified shell powder to formaldehyde is significantly improved. |
