Heat-resistant and anti-drying PVC base wallpaper and preparation method thereof

Abstract

The invention relates to a base wallpaper, and particularly relates to a heat-resistant and anti-drying PVC base wallpaper and a preparation method thereof. The base wallpaper is prepared from the following raw materials in parts by weight: 30-40 parts of cotton pulp, 35-48 parts of coniferous pine wood pulp, 4-6 parts of polyaniline nanofibers, 0.1-0.2 part of taurine, 1-2 parts of glycolic acid, 0.1-0.2 part of sodium hyaluronate, 1-2 parts of poly-N-isopropyl acrylamide, 4-6 parts of a PAE wet strength agent, 12-16 parts of sepiolite fabric, 12-16 parts of 800-1250-mesh environment-friendly pigments, 10-15 parts of an adhesive and 3-5 parts of an assistant. The base wallpaper disclosed by the invention is doped with the polyaniline nanofibers, so that the paper has unique antistatic and anti-electromagnetic radiation efficacies; the taurine, the sodium hyaluronate and the like are capable of adjusting the humidity controlling ability of the paper and preventing drying and hair slip; the sepiolite fabric is capable of improving the heat resistance of the paper, and improving the dimensional stability of hot working; the composite surface coating liquid is uniform and full in color and luster, good in retention effect, and easy to coat; the finished base wallpaper is water-resistant, heat-resistant, lenitive, crisp, high in raw material utilization rate, and excellent in physical property; and a basis is laid for the production of a high-quality wallpaper product.

Description

technical field [0001] The invention relates to a wallpaper base paper, in particular to a heat-resistant 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 surface absorption, difficul...

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
