Abstract

The invention relates to the field of preparation of building materials, in particular to a preparation method of a diatomite wallpaper. According to the diatomite wallpaper prepared by the invention,the plant fibers are added into the diatomite, a toughening modification ethylene-vinyl acetate copolymer emulsion is used as an adhesive, and the adhesive is grafted by organic silicon after toughening modification, so that the prepared film is high in toughness and good in water resistance, and the scrubbing resistance and the flexibility of the obtained wallpaper are greatly improved. The wallpaper provided by the invention has high strength, beautiful appearance and good water resistance, and the surface is easy to clean and does not contain toxic substances. Meanwhile, due to the use ofthe diatomite, the effects of humidifying, deodorizing, removing toxic gas, sterilizing and the like are achieved. The novel wallpaper disclosed by the invention conforms to the life concept of modernpeople and has a good market prospect.

Description

technical field [0001] The invention relates to the field of preparation of new building materials, in particular to a preparation method of diatomite wallpaper. Background technique [0002] Wallpaper is a kind of special paper used to decorate walls. It has certain strength, rich colors, strong texture, rich patterns, good water resistance, and its surface is easy to clean, and it is non-toxic and environmentally friendly. Because the wallpaper has various colors, rich patterns, safety and environmental protection, luxurious style, convenient construction, reasonable price and other incomparable characteristics of other interior decoration materials. [0003] Yuan Peng et al., ~1H magic-angle spinning nuclear magnetic resonance spectrum of hydroxyl groups on the surface of diatomite, Science Bulletin, Issue 04, 2001, records: using high-speed 1H magic-angle spinning NMR technology, successfully distinguishing different types of Hydroxyl: isolated hydroxyl, hydrogen-bonded...
