The invention discloses foamed
wallpaper, and belongs to the field of decorative materials. According to the
wallpaper disclosed by the invention,
sodium polyacrylate,
tourmaline powder and inorganicnano anti-mold
powder are used as raw materials, and an
adhesive, a hardening agent, tackifying resin polyacrylate,
polyamide and hydrogenated
rosin are added to prepare a compound
emulsion, so that
mildew of a
wallpaper adhesive is inhibited, and a long-lasting
antibacterial effect is achieved; the hardening agent is added, so that ability of a base film to solidify and pulverize a wall surface is improved, and the wallpaper does not fall off in a large area; the
tourmaline powder has a degradation effect on harmful gases and protects the environment and human bodies,
moisture and alkaline substances of a construction wall surface are effectively prevented from being infiltrated to the outside, and an occurrence of phenomena that the wallpaper gets damp, gets
mildew, gets black and is discolored is prevented. The method disclosed by the invention solves the problems that in current wallpaper, a stronger-
pollution flame retardant is added into a printing layer and a
foaming agent containing
polyvinyl chloride is added into a foaming layer, so that produced pure paper wallpaper has a higher content of harmful substances, and surfaces of foaming holes are rough and easy to fall off.The invention provides a preparation method for the foamed wallpaper.
