Abstract

The present invention relates to a kind of anti-mosquito wallpaper base paper, the non-woven wallpaper base paper is made of functional fiber, wood pulp fiber and adhesive mixed papermaking or made of functional fiber, wood pulp fiber mixed papermaking and then coated with adhesive in machine , the fineness of the functional fibers is 0.8-25D, and the length is 2-65mm; the functional fibers include anti-mosquito fibers and other hydrophilic functional fibers, and the wood pulp fibers, anti-mosquito fibers and other hydrophilic functional fibers The weight ratio between the fibers is 10-80%: 5-60%: 5-80%, and the adhesive accounts for 1-20% of the total weight of the base paper. The anti-mosquito wallpaper produced by the invention can contain effective mosquito repelling ingredients up to 75 mg / m2, and the knockdown rate of mosquitoes within 60 minutes can reach 97%. Moreover, the wallpaper product does not shrink during processing, has no damp feeling, the paper is completely peeled off, the paper is very flexible, and has the function of knocking down mosquitoes attached to the surface of the wallpaper.

Description

technical field [0001] The invention relates to a non-woven wallpaper, in particular to a non-woven wallpaper base paper with anti-mosquito function, 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 pheno...
