Nano organic bentonite-negative ion stone-containing high adhesion health-type coating wallpaper

Abstract

The present invention discloses nano organic bentonite-negative ion stone-containing high adhesion health-type coating wallpaper, the wallpaper comprises base paper and a modified waterborne polyurethane coating applied to base paper surface, the prepared coating material not only inherits the non-toxic, heat-resistant and environmentally friendly characteristics of the waterborne polyurethane coating, and also has the advantages of water resistance, stain resistance, smooth hand feeling and the like, added polyvinyl alcohol is used as a dispersion solution of nano organic bentonite-negative ion stone powder for protecting colloid, is good in compatibility with the polyurethane emulsion, has thickening, cracking resistance, heat insulation, negative ion release and other effects, can also increase the porosity of the coating to form a microporous breathable structure for effectively protecting the base paper; the wallpaper prepared from the coating is safe, durable, good in adhesion to base paper surface, in low tendency to crack and spall, is water-resistant, heat-insulating, heat-resistant, and cold-resistant, and has strong market competitiveness.

[0002] Wallpaper, also known as wallpaper, is more and more widely used in home decoration because of its advantages of various colors, rich patterns, luxury style, safety and environmental protection, convenient construction, and affordable price. Layer composition, and the nature of the coating greatly determines the function of the wallpaper. At present, the wallpaper for interior decoration mainly tends to develop in the direction of environmental protection and safety. The choice of coating materials is also based on environmental protection and safety. There are also emerging in the market. A variety of environmentally friendly wallpapers decorated with multi-functional coatings, such as PVC resin coatings, flame-retardant coatings, diatomite purification coatings, etc. Poor material fit, easy to peel off due to environmental influences, high construction difficulty, etc., cannot safely meet the construction and use requirements
