Abstract

The invention discloses wall base paper and a preparation method thereof, and belongs to the field of special paper. The wall base paper is prepared from the following raw materials in parts by weight: 30-50 parts of softwood pulp, 40-60 parts of hardwood pulp, 10-15 parts of polyester fibers, 1-5 parts of a water repellent agent, 10-25 parts of a sizing agent and 1-4 parts of a wet strength agentPAE. The preparation method comprises the following steps: 1) preparing backing paper: weighing coniferous pine wood pulp and hardwood pulp in parts by weight; adding polyester fibers, a water repellent agent and a wet strength agent PAE, mixing, repulping and pulping with the pulping degree of 20-40 degrees SR, adding water to adjust the pulp concentration to be 2.5%-3% in percentage by mass, sparying the pulp to a net through a pulp flowing box of a paper machine, performing squeezing dehydration i through a squeezing part, drying through a drying part, and obtaining backing paper; 2) sizing; and 3) post-processing. The wall base paper has the advantages that the wall base paper is waterproof, breathable and excellent in flexibility, the wall base paper can be firmly adhered to wallpaper, and thus the problem of edge curling and falling of the wallpaper can be solved.

Description

technical field [0001] The invention belongs to the field of special paper, in particular to a wall base paper and a preparation method thereof. Background technique [0002] So far, the wall decoration materials used in the market are mostly latex paint and wallpaper. After half a year of use, ordinary latex paint will crack due to the brittle nature of the putty under the latex paint. The wallpaper only solves part of the problem in terms of appearance, and cannot play the role of crack resistance, and because the surface of the wallpaper is made of PVC, PVC is a special material of plastic products, which has completely airtight performance, so this kind of product is in the air humidity and humidity. If the difference is too obvious, it is easy to crack or even mold on the edge. Over time, defects such as yellowing, curling, and cracking of the wallpaper make the decoration effect poor and the service life insufficient. Since the main component of the paper base of the...
