Abstract

The invention relates to an anti-flaming non-woven paper and a preparation method thereof. The anti-flaming non-woven paper comprises the following raw materials by weight part: 70-99 parts of fiber slurry and 1-30 parts of adhesives, wherein the fiber slurry comprises a wood pulp fiber and a functional fiber; the quantity of the wood pulp fiber is 0%-95%; the quantity of the functional fiber is 5%-100%; and the anti-flaming non-woven paper is prepared by processing the functional fiber, the wood pulp fiber and the adhesives or mixing and processing the functional fiber and the wood pulp fiber and then using an adhesive machine for coating inside. A natural stripe appears on the surface of the anti-flaming non-woven paper provided by the invention; the appearance is beautiful; no additional treatment is required; and meanwhile, the anti-flaming non-woven paper product does not contract during a processing process and is free from moist feel; paper uncovering is complete; the flexibility of the paper is excellent; the paper is not burned under the flame and is free from flame; and the paper is only carbonized at the temperature above 400 DEG C, so that the product has excellent anti-flaming property.

Description

technical field [0001] The invention relates to a flame-retardant non-woven paper, in particular to a flame-retardant non-woven wallpaper substrate and a preparation method thereof. Background technique [0002] Flame-retardant non-woven wallpaper is a new type of wall decoration material. It has the characteristics of rich colors, strong muscle texture, bright patterns, green environmental protection, convenient construction, cheap price, good decorative effect, noble and elegant, etc. It is an ideal choice for other urban decoration. The material is incomparable. However, most of the wallpapers in the market today are PVC wallpapers and pure paper wallpapers based on wood pulp fibers. Although these two wallpapers are cheap, they have irreparable shortcomings. dirt, and because the air permeability of these two kinds of wallpapers is poor, the moisture in the air is not easy to escape, which leads to problems such as bubbling, edge warping, and seams on the wallpaper. St...
