Ventilating and permeable PVC base wallpaper with lasting fixation and preparation method thereof

Abstract

The invention relates to a base wallpaper, and in particular relates to a ventilating and permeable PVC base wallpaper with lasting fixation and a preparation method thereof. The base wallpaper consists of the following raw materials by weight: 8-10 parts of bacterial cellulose, 34-40 parts of cotton pulp, 32-40 parts of softwood bleached pulp, 0.1-0.2 part of methylisothiazolinone, 1-2 parts of salicylic acid, 3-4 parts of a PAE wet strength agent, 8-10 parts of calcined kaolin of 600-800 mesh, 3-5 parts of white bamboo charcoal fine powder, 5-8 parts of cellulose ether, 1-2 parts of sodium polyphosphate, 12-16 parts of green paint of 800-1250 mesh, 10-15 parts of an adhesive and 3-5 parts of an auxiliary agent. The base wallpaper has good ventilating and permeable performance, high wet strength and improved durability; calcined kaolin and white bamboo fine powder can assist the fixation of pulp and realize good dimensional stability; a complex surface coating liquid can effectively improve strength of base paper and strengthen the water resistance; and the base paper finished has smooth and compact surface, is environment-friendly, non-toxic, ventilating and permeable, and has the advantages of no moisture regain deformation, excellent physical properties and easiness for after processing, and lays foundation for the production of high quality wallpaper products.

Description

technical field [0001] The invention relates to a wallpaper base paper, in particular to an air-permeable, water-permeable and durable PVC wallpaper base paper and a preparation method thereof. Background technique [0002] As a wall decoration material, wallpaper has gradually become the first choice of many owners. It has various colors, rich patterns, beautiful and environmental protection, etc. It has many incomparable advantages of traditional wall materials. The utilization rate in our country is increasing year by year. PVC wallpaper is A common type of wallpaper, which mostly uses pure paper as the substrate, and then coats PVC resin on the surface of the substrate, and then undergoes post-finishing processing to obtain the finished product. [0003] Base paper as the base material directly affects the process effect and quality of wallpaper in the later stage. At present, base paper materials generally have disadvantages such as poor strength, poor toughness, uneven...

Problems solved by technology

[0003] Base paper as the base material directly affects the process effect and quality of wallpaper in the later stage. At present, base paper materials generally have disadvantages such as poor strength, poor toughness, uneven surface absorption, difficult application of glue, poor water resistance and heat resistance, and mold growth. , seriously affects the performance of the finished product, so it is very important to improve the formula and process of traditional base paper, improve its adaptability, and improve the post-processing performance to achieve efficient production and obtain high-quality products
