[0003] The most common coating slurry currently on the market is mainly composed of PVC resin and fillers. Although this coating material has the advantages of being beautiful, durable and waterproof, it has poor air permeability and contains organic solvents, which will pollute the indoor air after long-term use. , with the improvement of people's awareness of environmental protection, the environmental protection requirements for wallpaper are getting higher and higher, which undoubtedly requires the use of new coating materials to replace PVC resin
In recent years, a number of environmentally friendly water-based resin coating materials have emerged on the market. Although these materials do not contain volatile organic solvents, they have excellent performance in terms of air permeability, plasticizing temperature, additional functionality, and adhesion to substrates. There are still deficiencies

Abstract
The invention discloses wallpaper containing a nano calcium carbonate crystal whisker-polylactic acid porous fiber modified acrylic resin emulsion coating. According to the wallpaper, a resin binding agent used by coating paste is cellulose acetate copolymerized modified waterborne acrylic resin emulsion; the emulsion has stable performances and does not contain chronic volatile toxic compounds including formaldehyde; the formed coating is smooth and elastic, and has waterproof, antifouling and antibacterial effects and the like; compared with traditional PVC (Polyvinyl Chloride) paste, the plasticizing temperature can be reduced to 120-150 DEG C; nano calcium carbonate crystal whisker-polylactic acid porous fibers containing nano silver can be used for effectively improving the air permeability of the coating and the mechanical property of the coating is improved, so that the wallpaper is relatively durable; and the wallpaper has vibration-absorption, noise-reduction and sterilization effects and the like and can be used for effectively improving an indoor environment.
Description
technical field [0001] The invention relates to the technical field of wallpaper, in particular to a wallpaper containing nano calcium carbonate whiskers-polylactic acid porous fiber modified acrylic resin emulsion coating. Background technique [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. Most common wallpapers are based on pure paper, non-woven fabrics and other materials. The material is coated with resin slurry on its surface, and it is made through high-temperature plasticization, printing and embossing and other processes. [0003] The most common coating slurry currently on the market is mainly composed of PVC resin and fillers. Although this coating material has the advantages of being beautiful, durable and waterproof, it has poor air permeability and contains orga...
