NOVELTY - Processing of building waterproof coating involves weighing raw material including 30-35 wt.% heavy calcium powder, 30-35 wt.% nano-calcium carbonate, 5-14 wt.% graphene, 0.5-1 wt.% nano-titanium dioxide, 0.5-0.8 wt.% antifoaming agent, 0.4-0.8 wt.% thickener, 0.4-0.8 wt.% preservative, 2.5-3.5 wt.% sodium bentonite, 0.2-0.4 wt.% antifungal agent and remainder of tributyl phosphate, drying nano-calcium carbonate and heavy calcium carbonate at 112-119 degrees C, such that the moisture content is 0.76% or less and 0.46% or less, respectively, ball-milling dried heavy calcium carbonate, dried nano-calcium carbonate, graphene, nano-titanium dioxide and sodium bentonite for 22-29 minutes, adding ground material to a stirring device, adding defoaming agent, thickener, preservative, antifungal agent and tributyl phosphate, stirring at 800-900 rpm for 0.7-1 hour, performing quality inspection of obtained coating, conveying qualified product to a storage tank for temporary storage, and packing. USE - Processing of building waterproof coating.
