Abstract

The invention discloses a preparation method of high-grade matt pure paper wallpaper and a beating and stirring device thereof. The matt pure paper wallpaper prepared by the method solves the phenomenon of reflection caused by excessively high gloss of coated wallpaper currently on the market, so that the paper has low surface gloss, good fineness, excellent strength, good softness, and printing color and luster. It has the advantages of fullness and strong three-dimensional sense. At the same time, the beating method using mechanical and ultrasonic in the beating and stirring device can not only improve the beating quality, improve the physical properties of the base paper, but also reasonably recover the heat generated in the beating process for other purposes, energy saving and environmental protection. .

Description

technical field [0001] The invention relates to the technical field of special paper, in particular to a beating and stirring device for preparing high-grade matt pure paper wallpaper. Background technique [0002] Wallpaper, also known as wallpaper, is an interior decoration material used to paste walls. In recent years, with the continuous heating up of interior decoration materials in our country, wallpaper has gradually entered the living room, bedroom, hotel, meeting room and other places due to its unique advantages. It has become a new type of decoration material that is popular among people. Pure paper wallpaper uses whole plant fiber as the main raw material, the surface is coated and processed, and it is specially processed after printing with water-based ink. It has the advantages of breathability, good covering, and bright and full color. Compared with traditional PVC wallpaper, this direct printing product does not contain PVC, has good air permeability, does n...
