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 ...

Abstract

The invention discloses a PVC foaming coating. The PVC foaming coating comprises, by weight, 330-350 parts of environmentally-friendly plasticizer, 360-390 parts of PVC paste resin, 15-18 parts of liquid stabilizer, 20-22 parts of AC foaming agent, 20-22 parts of microsphere foaming agent, 75-80 parts of titanium dioxide, 250-275 parts of ground calcium carbonate and 30-33 parts of matting agent. By means of the potassium/zinc liquid stabilizer, the AC foaming agent and the microsphere foaming agent, the foaming function of the PVC foaming coating can be effectively improved, the foaming ratio of PVC foaming wallpaper can be improved, and satisfactory foaming quality can be obtained.

Description

technical field [0001] The invention relates to a PVC foam paint, a PVC foam wallpaper and a preparation method thereof. Background technique [0002] PVC foam wallpaper is a new type of indoor wall decoration material. The surface of the wallpaper is full of elastic concave-convex patterns, and patterns can be printed on the foam plane, such as relief, wood grain, tiles, etc., with realistic patterns. Strong three-dimensional effect, good decorative effect, sound absorption and heat preservation, etc. [0003] The PVC foam wallpaper currently in use mainly uses PVC paste resin as the main raw material, and the performance of PVC paste resin has an important impact on the quality of foam wallpaper products. Therefore, in the process of preparing PVC foam coatings, various additives such as stabilizers, foaming agents, and plasticizers are usually added to prepare PVC coatings with excellent performance. However, the foaming function of the PVC foaming coating currently in ...
