Abstract

The invention relates to a non-woven wall paper, in particular to a long fiber non-woven wall paper raw paper and the preparation method and the non-woven wall paper prepared in the method. The long fiber non-woven wall paper raw paper comprises fiber pulp material and adhesive agent, wherein the fiber pulp material comprise wood pulp fiber and functional fiber, the weight proportion between the wood pulp fiber and the functional fiber adopts 0 to 95 percent to 5 to 100 percent, and the adhesive agent occupies 1 to 10 percent of the total weight of the raw paper; the functional fiber at least contains a functional fiber which fineness is 0.8 to 25 D, and which length is 15 to 60 mm. The surface of the wall paper in the invention presents natural stripes, the outer appearance is artistic, and further treatment is not required. Simultaneously, during the wall paper product processing, no shrinkage and moist feeling occur, the paper uncover is complete, and the paper flexibility is good. The wall paper product adopting flame-resistant fiber can be burnt on the fire source, the fire is extinguished after leaving the fire source, and the non-woven wall paper has a good flame-resistant performance.

Description

technical field [0001] The invention relates to a non-woven wallpaper, in particular to a long-fiber 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...
