Abstract

The invention relates to a non-woven wallpaper, particularly relates to a non-woven wallpaper base paper and the non-woven wallpaper prepare by the base paper. The non-woven wallpaper base paper comprises a fiber pulp and an adhesive, wherein, the fiber pulp includes a wood-pulp fiber and a function fiber, the weight ratio of the wood-pulp fiber and the function fiber is 0-95%: 5-100%, and the adhesive accounts for 1-10% of the gross weight of the base paper. The wallpaper of the invention does not contract when processed, does not have moist feeling, is complete when uncovered, and has good flexibility. The wallpaper made by a flame-resistant fiber is able to burn under the fire, but extinguishes after leaving the fire, and has good flame-resistant performance.

Description

technical field [0001] The invention relates to a non-woven wallpaper, in particular to a non-woven wallpaper base paper, a preparation method thereof and a non-woven wallpaper prepared therefrom. Background technique [0002] Non-woven wallpaper is a new type of wall decoration material. It has the characteristics of rich colors, strong texture, bright patterns, green and environmental protection, convenient construction, reasonable price, noble and elegant decorative effects, etc., which is unmatched by other interior decoration materials. However, the previous wallpapers used wood pulp fiber as the basic material. This kind of wallpaper is cheap, and its disadvantages are poor performance, water resistance, inconvenient cleaning, and inconvenient construction. There is often a sense of humidity, and black spots will appear after a long time. When replacing the wallpaper, due to its own poor strength, the peeling is not complete, and the phenomenon of sticking to the wal...
