[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

Embodiment Construction
[0016] The wallpaper of this embodiment is made of a non-woven fabric substrate and a coating slurry coated on the surface of the substrate after drying, plasticizing, and embossing, wherein the coating slurry is made of the following raw materials in parts by weight: composite Water-based acrylic resin emulsion 80, polylactic acid chips 8, organic montmorillonite powder 3, vinyl distearic acid amide 0.1, nano barium titanate 1, silane coupling agent kh5500.1.
[0017] The coating slurry preparation method is:
[0018] (1) Preparation of organic montmorillonite polylactic acid porous fiber: First, mix polylactic acid slices, vinyl bis stearic acid amide, organic montmorillonite micropowder, nano-barium titanate, and silane coupling agent kh550, and then carry out melt spinning Silk, made into porous short fibers with a length of 50 μm and a diameter of 30 μm;
[0019] (2) Put the organic montmorillonite polylactic acid porous fiber into the composite water-based acrylic resin...

Abstract
The invention discloses a modified acrylic resin emulsion coating-containing environmental protection and wave absorption wallpaper. A resin adhesive adopted in a coating slurry used by the wallpaper is a cellulose acetate copolymer modified aqueous acrylic resin emulsion, the emulsion has stable performances and contains no formaldehyde or other chronic volatile toxic compounds, and a coating formed by the emulsion is smooth and elastic and has water resistance, antifouling and antibiosis functions; compared with traditional PVC pastes, the coating has a low plasticizing temperature reaching 120-150DEG C; and added nanometer barium titanate-containing organic montmorillonite-polylactic acid porous fibers can effectively improve the permeability of the coating, have certain reinforcing and toughening effects, can purify indoor air, have wave absorption efficacy, and make the coating be suitable for being used as a television wall wallpaper coating. The novel wallpaper has the advantages of durability, repeated scrubbing, economy and environmental protection.
Description
technical field [0001] The invention relates to the technical field of wallpaper, in particular to an environmentally friendly wave-absorbing wallpaper containing a 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 solvents, whic...
