Problems solved by technology

However, mixing shrub wood pulp fibers in pulp usually leads to loose paper and a decrease in strength, which makes it difficult to meet the strength requirements of wallpaper; moreover, wallpaper made of pure paper has a problem of poor water resistance due to its high hydrophilicity. Due to the loose texture and poor water resistance of wallpaper mixed with shrub wood pulp fibers, the problem of poor water resistance is more serious, and it is very prone to leakage

Abstract

The invention discloses environment-friendly water-resistant wallpaper which is prepared by coating or spraying a surface treating agent on the surface of base paper and drying. The base paper is prepared from the following raw materials in parts by mass: 15 to 25 parts of carambola pulp, 15 to 25 parts of bamboo pulp, 50 to 70 parts of softwood pulp, 10 to 20 parts of filler and 1 to 2 parts of sizing agent; the surface treating agent comprises the following raw materials in parts by mass: 1-2 parts of nano cellulose, 1-2 parts of stearic acid, 3-6 parts of a silane coupling agent and 80-120 parts of absolute ethyl alcohol. The invention further discloses a preparation method of the environment-friendly water-resistant wallpaper. The environment-friendly water-resistant wallpaper disclosed by the invention not only has excellent strength and water resistance, can prevent leakage, but also has good air permeability, is environment-friendly and pollution-free, improves the recycling rate of natural resources, and has good environmental benefits.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to an environment-friendly water-resistant wallpaper and a preparation method thereof. Background technique [0002] Wallpaper, also known as wallpaper, is an interior decoration material used to paste walls, and is widely used in residences, office buildings, hotels and other places. The materials of wallpaper are very diverse, including PVC, pure paper, etc. Among them, PVC is a synthetic material, which is easy to release volatile organic compounds, and its safety and environmental protection performance is poor; pure paper is mainly made of coniferous wood pulp, hardwood pulp, bamboo pulp, etc. Processed as a raw material, it has the advantages of being natural, safe and non-toxic. However, due to the large shortage of natural resources such as wood and bamboo for papermaking, their costs are increasing day by day. [0003] Carambola trees, also known as carambola...
