[0033] A preparation method of the quick-drying soft porcelain real stone paint, comprising the following steps: base water glass and quaternary ammonium salt, and continue to stir at 400-800 rpm for 10-15 minutes;
[0034] b: Under normal temperature and pressure, continue to add silane coupling agent and defoamer to the container with a stirrer, and disperse for 5-15 minutes at a speed of 600-900 rpm;
[0035] c: Under normal temperature and pressure, add 120-180 mesh quartz sand and 40-80 mesh quartz sand to the mixture obtained in step b, and disperse at 700-1100 rpm for 5-15 minutes, and then stand still for 20-50 Within minutes, you can get quick-drying soft porcelain stone paint.
Embodiment 1
