Abstract

The invention relates to a preparation method of antibacterial mildewproof silk wallpaper and antibacterial mildewproof silk wallpaper obtained according to the preparation method. The preparation method comprises the following steps: drying, colloidizing and cooling a functional layer, and then compounding with silk fabric base layer through hot rolling process to produce silk wallpaper; the quality ratio and preparation method of the functional layer are as follows: adding 100 parts of polyvinyl chloride (PVC) and 10-50 parts of dioctyl phthalate plasticizer into a dispersing bucket and stirring uniformly; sequentially adding 20-100 parts of calcium carbonate filler, 5-10 parts of azodicarbonamide foaming agent, 10-25 parts of titanium dioxide, 2-8 parts of styrene acrylic binder and 2-8 parts of butylmercaptooxo-stannane stabilizer; after stirring and dispersing uniformly, further adding 2-10 parts of nano zinc oxide-nano bamboo charcoal composite particles and dispersing uniformly; grinding and filtering; and thus obtaining the functional layer. The silk wallpaper prepared according to the preparation method provided by the invention is obviously persistent in antibacterial and mildewproof effect, strong in odor removing effect and long in service life, and is an environment-friendly decorating material.

Description

technical field [0001] The invention belongs to the field of preparation of multifunctional wallpapers, and in particular relates to a method for preparing antibacterial and mildew-resistant silk wallpapers containing nano-zinc oxide-nano-bamboo charcoal composite particles, and the antibacterial and mildew-resistant silk wallpapers obtained therefrom. Background technique [0002] In recent years, people have higher and higher requirements and tastes for interior decoration, and a new type of silk wallpaper was born. Silk symbolizes a kind of elegance and luxury, and is known as the "Queen of Fabrics". It has the characteristics of keeping warm and absorbing moisture, rich in color and not easy to fade with water, etc., and is loved by people. The silk wallpaper made of it is one of the most popular high-grade interior wall decoration materials today. However, due to its protein nature and good hygroscopicity, silk wallpaper has defects such as easy mold, which affects ...
