Embodiment 1
[0030] The preparation method of PVC foam wallpaper: comprises the following steps:
[0031] Step 1. Put 330 parts of environment-friendly plasticizer and 15 parts of liquid stabilizer into the mixing tank, turn on the agitator to stir at 1000 rpm, and heat to 40 degrees Celsius at the same time, and continue to stir at 1000 rpm , and while stirring, put in 360 parts of PVC paste resin, 20 parts of AC foaming agent, 20 parts of microsphere foaming agent, 75 parts of titanium dioxide, 250 parts of heavy calcium, and 30 parts of matting powder. Continue stirring at a speed of 1200 rpm for 30 minutes to obtain a crude product;
[0032] Step 2, filtering the above-mentioned crude product through an 80-mesh filter to obtain a slurry;
[0033] Step 3: Evenly coat the above-mentioned slurry with a thickness of 1 mm on the base cloth, then bake in an oven at 200 degrees Celsius for 0.5 minutes, heat and plasticize to form a semi-finished wallpaper;
[0034] Step 4: Print and emboss ...
