Abstract

The invention discloses a novel environmentally-friendly nanometer photocatalyst formaldehyde scavenger. The novel environmentally-friendly nanometer photocatalyst formaldehyde scavenger is prepared from, by weight, 10%-15% of silk fibroin peptidyl surfactant, 5%-10% of formaldehyde capture agent, 2%-5% of photocatalyst, 0.1%-0.5% of nanometer silver colloid, 0.5%-0.8% of nano-silicon dioxide, 0.5%-0.8% of nano-titanium dioxide, 0.1% of osmotic agent and the balance water. The novel environmentally-friendly nanometer photocatalyst formaldehyde scavenger can reach 3.5 nm, the permeation property and penetration property are strong, the nanometer diameter is relatively small, and the purposes of sterilization, disinfection and deodorization are really achieved; the photocatalyst is adopted to select platinum-loaded nanometric anatase type titanium dioxide, the scavenger is not limited by light and temperature, the application conditions are mild, the scavenger can be effectively catalyzed under any beam, formaldehyde can be completely converted into water and carbon dioxide, through the addition of the silk fibroin peptidyl surfactant, the formaldehyde can be further effectively cleared, and the complete elimination of the formaldehyde is really achieved.

Description

technical field [0001] The invention relates to the technical field of formaldehyde scavenger, in particular to a novel environment-friendly nano photocatalyst formaldehyde scavenger. Background technique [0002] Formaldehyde is a colorless, highly irritating gas that is volatile. Formaldehyde is one of the main pollutants in the indoor environment, and has been identified as carcinogenic and teratogenic substances by the World Health Organization. The World Health Organization (WHO) stipulates that the safe concentration of exposure to formaldehyde within 30 minutes is 80ppb, and the U.S. Occupational Safety and Health Administration (OSHA) regulations allow [0003] The formaldehyde exposure concentration is 750ppb, while the extreme dangerous level (industrial DLH) is 20ppm. Inhalation of high concentrations of formaldehyde can cause severe irritation and edema of the respiratory tract, eye irritation and headache. Long-term exposure to low concentrations of formaldeh...
