▎ 摘　　要

NOVELTY - Polymer cement waterproof coating comprises liquid material and powder material, where the ratio of liquid material and powder material is 1:2.5-3. The liquid material comprises 100-125 pts. wt. modified styrene-acrylic emulsion, 0.1-1.5 pts. wt. antibacterial agent, 125-150 pts. wt. water, 1-3 pts. wt. thickener and 3-6 pts. wt. film forming agent and the powder comprises 225-250 pts. wt. portland cement, 225-250 pts. wt. heavy calcium, 320-340 pts. wt. quartz sand, 1-3 pts. wt. superplasticizer, 1-2 pts. wt. wetting and dispersing agent and 25-40 pts. wt. graphene oxide. USE - Polymer cement waterproof coating. ADVANTAGE - The polymer cement waterproof coating is capable of capturing formaldehyde and purifying air and has good low-temperature flexibility, strong low temperature bridging ability, good acid corrosion resistant effect, and high antibacterial rate. DETAILED DESCRIPTION - Polymer cement waterproof coating comprises liquid material and powder material, where the ratio of liquid material and powder material is 1:2.5-3. The liquid material comprises 100-125 pts. wt. modified styrene-acrylic emulsion, 0.1-1.5 pts. wt. antibacterial agent, 125-150 pts. wt. water, 1-3 pts. wt. thickener and 3-6 pts. wt. film forming agent and the powder comprises 225-250 pts. wt. portland cement, 225-250 pts. wt. heavy calcium, 320-340 pts. wt. quartz sand, 1-3 pts. wt. superplasticizer, 1-2 pts. wt. wetting and dispersing agent and 25-40 pts. wt. graphene oxide. The modified styrene-acrylic emulsion comprises 3.5-5 pts. wt. styrene, 2-4 pts. wt. methyl methacrylate, 3.5-6 pts. wt. butyl acrylate, 1.4-2.8 pts. wt. methacrylic acid, 1.2-2.6 pts. wt. hydroxypropyl methacrylate, 0.55-0.7 pats. wt. ammonium persulfate, 0.3-0.5 pts. wt. sodium bicarbonate, 10-15 pts. wt. ammonia, 30-50 pts. wt. deionized water, 2.5-3 pts. wt. composite emulsifier, where the composite emulsifier includes disodium sulfosuccinate decyl polyoxyethylene ether ester and sodium 2-acrylamide-2 methyl propane sulfonate in ratio of 1:0.8-1.
