The invention discloses a nano-composite formaldehyde decomposition material, comprising the following components in parts by mass: 100 parts of amino-modified sepiolite, 10-20 parts of 2-imidazolidinone, 5-10 parts of imidazolidinyl urea, solid chlorine dioxide 0.5-1 part, 15-30 parts of lanthanum/cerium doped nano tourmaline powder, 10-20 parts of nano-copper sulfide/silver phosphate modified hexacyclic stone, 2-4 parts of silver-loaded zirconium phosphate, 5 parts of zinc ricinoleate ~10 parts, 5-10 parts of pregelatinized starch. The present invention adopts amino-modified sepiolite, 2-imidazolidinone, imidazolidinyl urea, solid chlorine dioxide, lanthanum/cerium doped nano tourmaline powder, nano copper sulfide/silver phosphate modified hexacyclic stone complex for the first time Equipped with formaldehyde purification materials, the five synergistic effects can achieve the immobilization and long-lasting degradation of formaldehyde. |
