Embodiment 7～12

[0031] The preparation method of embodiment 7~12 adopts following steps:

[0032] a) Control the degree of beating of the coniferous plant fibers in the wood pulp fibers at 15 to 20°SR, and the broad-leaved plant fibers in the wood pulp fibers are fully dispersed by a disintegrator until the fibers are even and there are no pulp lumps, and then the two kinds of wood Pulp fiber and chemical fiber are mixed in proportion, using a pulper to finely grind, disintegrate, and beat. The beating degree is 30-32°SR, and the beating concentration is controlled at 2-5%;

[0033] b) adding inorganic fillers and chemical additives to the pulper for batching, and adjusting the pH value to 7-8 with aluminum sulfate to form a mixed fiber slurry;

[0034] c) copying and drying the mixed fiber slurry described in step b) through a fourdrinier paper machine to obtain a base paper semi-finished product;

Abstract

The invention relates to an environment-friendly high-printability non-woven wallpaper base and a preparation method thereof, belongs to the field of processing of non-woven fabric and mainly relates to the environment-friendly high-printability non-woven wallpaper base and the preparation method thereof. The environment-friendly high-printability non-woven wallpaper base comprises the following components in percentage by weight: 50-80 parts of wood pulp fiber, 20-50 parts of chemical fiber, 1-19 parts of inorganic filler, 10-20 parts of latex, 1.1-5 parts of chemical additives and 1-4 parts of surface treating agent, wherein the wood pulp fiber is of a mixture formed by mixing softwood pulp fiber and hardwood pulp fiber according to the weight ratio of 3-9: 1. The environment-friendly high-printability non-woven wallpaper base disclosed by the invention has the advantages of uniform ink absorption, strong color spreading capability, lower flexibility, higher softness, good printability, economy and environment-friendly property.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to an environment-friendly and highly printable non-woven wallpaper base paper. Background technique [0002] At present, there are various types of wallpapers on the market and emerge in endlessly, such as glue-faced PVC wallpapers, pure paper wallpapers, metal wallpapers, liquid wallpapers, wood-faced wallpapers, etc. Recently, a new type of material wallpaper - non-woven wallpaper has become popular in the domestic high-end home market, mainly used for living room, bedroom or study decoration. Because the shape made of fabric is more convex and concave, and it is easier to reflect individuality. Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials with the characteristics of moisture-proof, breathable, non-combustible, easy to decompose, and recyclable. Non-...
