Environment-friendly pollution-free PVC wallpaper capable of removing formaldehyde
The invention provides environment-friendly pollution-free PVC wallpaper capable of removing formaldehyde. The processing method of the wallpaper comprises the steps that the compositions of a formaldehyde absorption layer are added into a stirred tank to be stirred evenly, heating is conducted after stirring, and a formaldehyde absorption layer base material is obtained; allyl benzene and paraffin are added into the stirred tank to be stirred, heating is conducted after stirring is completed, then a stabilizing agent, ammonium hydroxide and sodium carbonate are added into the stirred tank to be stirred, the materials are naturally cooled to be at the normal temperature after stirring is completed, and a damp-proof course base material can be obtained; a PVC wallpaper layer which is processed to be formed is put in liquid nitrogen to be quickly frozen, and then the formaldehyde absorption layer base material is evenly smeared on the upper surface of the PVC wallpaper layer which is quickly frozen; drying treatment is conducted after smearing is completed; the damp-proof course base material is evenly smeared on the lower surface of the treated wallpaper, and drying is conducted. An original wallpaper layer is wrapped with a formaldehyde absorption layer, a macromolecule formaldehyde adsorbent and nanoscale active carbon granules are adopted, large area of formaldehyde in indoor air can be absorbed, and the environment is improved.
