Wallpaper containing a porous silicon carbide-polylactic acid porous fiber modified acrylic resin emulsion coating

Abstract

The invention discloses wallpaper containing a porous silicon carbide-polylactic acid porous fiber modified acrylic resin emulsion coating. A cellulose acetate-copolymerized modified waterborne acrylic resin emulsion is adopted as a resin adhesive in coating slurry used for the wallpaper, and is stable in performance and free of toxic compounds slow in volatilization such as formaldehyde. The formed coating is smooth and elastic and has waterproof, antifouling and antibacterial functions and the like. Compared with traditional PVC paste, plasticizing temperature of the coating can be reduced to 120-150 DEG C. Added porous silicon carbide-polylactic acid porous fibers can endow the coating with excellent gas permeability, effectively improved mechanical strength and highly preponderant wear resistance. The surface of the wallpaper is not liable to scratch. The wallpaper is durable.

Description

technical field [0001] The invention relates to the technical field of wallpaper, in particular to a wallpaper containing a porous silicon carbide-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 organic sol...

[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
