Example Embodiment
[0016] The wallpaper of this embodiment is made from 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 by weight: Aqueous acrylic resin emulsion 80, polylactic acid chips 8, pearlescent powder 3, ammonium polyphosphate 1, 30% polyethyleneimine solution 5, vinyl bisstearic acid amide 0.1, and silane coupling agent kh5500.1.
[0017] The coating slurry preparation method is:
[0018] (1) Preparation of pearlescent powder polylactic acid porous fiber: firstly, polylactic acid chips, pearlescent powder micropowder, ammonium polyphosphate, vinyl bisstearic acid amide, silane coupling agent kh550 are stirred and mixed uniformly, and then melt-spinned to make length Porous short fibers with a diameter of 50μm and a diameter of 50μm;
[0019] (2) Put the pearlescent powder polylactic acid porous fiber into the composite water-based acrylic resin...
