Abstract

The invention discloses a photocatalyst coating film and application of the photocatalyst coating film in indoor air purification. The photocatalyst coating film is prepared from the following components: nano titanium dioxide, butyl methacrylate, diacetyl tartaric acid monoglyceride and diglyceride, isobutyl acrylate, isobutyl methacrylate, sodium tripolyphosphate, styrene, sodium stearoyl lactylate, casein phosphopeptides, p-toluenesulfonic acid, a sulfonate type surfactant, a nonionic antistatic agent, sodium carbonate, butyl hydroxy anisd and an enhancer. The enhancer is a mixture of xanthan gum and ovomucin. The photocatalyst coating film can be applied to indoor air purification. According to the photocatalyst coating film, the purification efficiency of methylbenzene and formaldehyde is improved, the purification efficiency of methylbenzene can reach 76%, and the purification efficiency of formaldehyde can reach 92%. In a purification effect durability test, the purification efficiency of methylbenzene can reach 66%, and the purification efficiency of formaldehyde can reach 87%.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification, in particular to a photocatalyst coating film and the application of the photocatalyst coating film in indoor air purification. Background technique [0002] Formaldehyde is generally considered to be the number one indoor killer, especially for infants, pregnant women, the elderly and patients with chronic diseases. Its main sources include several aspects: various types of phenolic resin glue-based wood-based panels used as decorative materials such as wall panels and ceilings, such as plywood, fine wood boards, fiberboards, and particle boards; decorative materials that contain formaldehyde and may emit to the outside world , such as wall coverings, wallpaper, paint and paint pipes; indoor displays and daily necessities that may emit formaldehyde, such as furniture, chemical fiber carpets, and foam plastics; certain materials that emit formaldehyde after burning, such as cigare...
