Compound-function wallpaper and preparation method thereof

Abstract

The invention discloses compound-function wallpaper and a preparation method thereof. The compound-function wallpaper is sequentially formed by a substrate layer, a glue sticking layer and a decoration layer from bottom to top, wherein the substrate layer is non-woven paper, non-woven cloth or plain weaving fabric which is processed by flame retardant finishing liquid; the glue sticking layer is formed by a binding agent, flame retardant powder, formaldehyde removing ultrafine powder and an additive; the formaldehyde removing ultrafine powder is formed by titanium dioxide ultrafine powder, zinc oxide ultrafine powder, tin oxide ultrafine powder, zinc sulfide ultrafine powder, ferric oxide ultrafine powder and diatomite ultrafine powder; and the decoration layer is a printing layer or an electrostatic flocking layer which is processed by the flame retardant finishing liquid. According to the compound-function wallpaper and the preparation method, disclosed by the invention, the flame retardant processing in each manufacturing technology stage of the compound-function wallpaper is realized, the all-directional fire flame retardant can be achieved, and the moisture regain is low; compound powder which can be used for catalyzing, resolving and removing formaldehyde in indoor environment is adopted for replacing common adsorptive material, thus the formaldehyde in the environment can be completely removed, and the repeatability does not exist; and selected anti-bacteria and mildew-proof anion far infrared products are both mature products in a market, and the multifunctional complex of the wallpaper is realized.

Description

technical field [0001] The invention relates to a composite functional wallpaper and a preparation method thereof, and relates to the technical field of interior decoration materials. Background technique [0002] Wallpapers make the home and indoor environment get rid of the monotonous white and become full of personality and interest. Colorful wallpapers are already indispensable in the home. With the continuous improvement of people's requirements for home and indoor living environment, the characteristics of wallpaper limited to decoration can no longer meet the increase of people's needs. It is impossible to only consider beauty in decoration, and safety, environmental protection and health are more important. So some wallpapers with special functions came into being. For example: the deodorant wallpaper disclosed by the patent application whose publication number is CN102251441A, the far-infrared anion wallpaper disclosed by the patent application whose publication nu...

Problems solved by technology

However, using this method, the following two situations often occur. One is that the pores of the porous material are mostly blocked by the adhesive and lose the adsorption effect; the other is that the adsorbent has a certain saturation value. Adsorption, in addition, there is a reversible process of adsorption and desorption with changes in the environment (such as indoor humidity, temperature)

Therefore, the formaldehyde in the indoor environment cannot be fundamentally removed.

[0005] The known function of giving wallpaper fire and flame retardancy is mostly the flame retardancy of the single matrix layer, and other substances attached to the matrix layer, such as adhesives, are flammable, and the fluff implanted is flammable, so that the wallpaper as a whole Flame retardant is difficult to meet the fire protection requirements stipulated by the state

The known flame-retardant wallpapers all have relatively serious moisture resurgence, which affects their performance
