Abstract

The invention discloses a method for preparing waterproof wallpaper. The method includes (1), mixing isopropyl alcohol, dispersing agents, polyvinyl chloride, sorbic acid, acrylic resin, carbon black, defoaming agents and bamboo charcoal powder with one another to obtain waterproof coating; (2), carrying out preheating treatment on paper; (3), coating the waterproof coating on the paper after preheating treatment is carried out on the paper and heating and embossing the paper to obtain the waterproof wallpaper. The weight-average molecular weight of the polyvinyl chloride is 50-60 thousand. The method has the advantages that the waterproof wallpaper prepared by the aid of the method has a characteristic of waster impermeability, and accordingly waterproof effects can be realized by the waterproof wallpaper.

Description

technical field [0001] The invention relates to a wallpaper, in particular to a waterproof wallpaper and a preparation method thereof. Background technique [0002] Wallpaper is an interior decoration material used to paste walls, and is widely used in interior decoration of houses, offices, hotels, and hotels. The material is not limited to paper, but also includes other materials. Because of its various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and reasonable price, it is widely used in many other interior decoration materials. Wallpapers are divided into many categories, such as laminated wallpapers, coated wallpapers, embossed wallpapers, etc. Usually bleached chemical wood pulp is used to produce paper, and then processed by different processes, such as coating, printing, embossing or surface coating, and finally cut and packaged before leaving the factory. However, the current commercially available wallpap...
