Problems solved by technology

However, the addition of polyvinyl chloride fiber, aramid fiber and carbon fiber will increase the difficulty of papermaking. In addition, due to the high price of existing flame-retardant fibers, this will lead to an increase in production costs. It is only suitable for high-end products. For ordinary products, then Still need to consider the cost of production

Abstract

The invention relates to flame-retardant nonwoven wallpaper and a preparation method of the flame-retardant nonwoven wallpaper. The wallpaper comprises body paper of nonwoven wallpaper, wherein the body paper of nonwoven wallpaper is prepared by mixing functional fiber, wood pulp fiber and adhesive and papermaking or coating in a machine through adhesive; one or a plurality layers of a flame-retardant coating are coated on the body paper of nonwoven wallpaper, the coating dosage accounts for 15-60% of the fixed paper quantity, the flame-retardant coating comprises a flame retardant, the flameretardant is a halogen-free flame retardant and is selected from one or a combination of a plurality of phosphorus-nitrogen synergistic flame retardants, and the flame retardant accounts for 50-100% of the flame-retardant coating. By adopting the technical scheme provided by the invention, the flame retardant grade of the produced nonwoven wallpaper flame is V-1 level, the production cost of the flame-retardant wallpaper is reduced, the wallpaper product is free of shrinkage in the processing process and is free of moist feeling, the discovered paper is integral, and the toughness of the paperis very good.

Description

technical field [0001] The invention relates to a wallpaper, in particular to a functional wallpaper with flame-retardant properties. 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 wall occurs. In addition, in terms of fire prevention, since wood...
