USE - Polymeric waterproof paint (claimed). ADVANTAGE - The coating layer formed from the polymeric waterproof paint has excellent water resistance and uniformly dispersed graphene. DETAILED DESCRIPTION - A polymeric waterproof paint comprises superhydrophobic material (A) and polymeric emulsion (B). The superhydrophobic material (A) comprises 2-10 parts mass graphene, 15-30 parts mass mixed acid solution, 5-12 parts mass aminoethoxysilane-toluene mixture, 5-12 parts mass fluorine-containing acrylate and 20-35 parts mass methanol solution. The polymeric emulsion comprises 35-55 parts mass hard monomer, 35-55 parts mass soft monomer, 2-5 parts mass functional monomer, 2-10 parts mass superhydrophobic material, 1-5 parts mass film-forming additives, 1-5 parts mass plasticizer, 0.8-1.5 parts mass emulsifier, 0.5-1 part mass dispersant, 0.5-1 part mass preservative, 0.05-1 part mass defoamer and 0.05-0.1 part mass initiator. The superhydrophobic material (A) is prepared by immersing graphene in mixed acid solution at room temperature for 25-45 minutes, washing the graphene with deionized water to pH of 6.8-7.2, drying in a high-frequency dryer to moisture content of 0.5-1%, immersing the resultant treated graphene in aminoethoxysilane-toluene mixture for 24-30 hours under argon atmosphere, removing excess aminoethoxysilane-toluene on the surface of the graphene by a centrifuge, drying with a vacuum dryer, forming 5-10 nu m-thick aminoethoxysilane-toluene film on the surface of the graphene, adding and mixing the resultant graphene with fluorine-containing acrylate, heating to 50-120 degrees C in an argon atmosphere, reacting for 1.5-3 hours, injecting methanol solution, processing for 2-5 hours, removing supernatant, centrifuging to remove excess methanol, vacuum drying at 70-75 degrees C for 1-2 hours and forming 2-5 nm-thick fluorine-containing acrylate film on the surface of the aminoethoxysilane-toluene film. The polymeric emulsion is prepared by adding deionized water to a reactor equipped with a stirring device, a condensing device, a nitrogen-protection device and a feeding device, stirring at 80 degrees C, adding pre-emulsion for 2.5-3.5 hours, mixing, adding initiator for 3.5-4 hours, stirring at 80-85 degrees C and 100 rpm for 30 minutes, adding film-forming additives, plasticizer, dispersant, defoamer and preservative, stirring at 80 rpm for 15-30 minutes, filtering, adding superhydrophobic material and ultrasonically-treating at 20-130 kHz for 3-5 minutes. The pre-emulsion is prepared by uniformly mixing hard monomer, soft monomer, functional monomer and emulsifier in deionized water, and stirring for 20-35 minutes. Also claimed is, preparation of polymeric waterproof paint, which involves adding polymeric emulsion (B) into a stirrer for 25-30 minutes, mechanically-stirring for 0.5-1.5 minutes, adding dispersant and superhydrophobic material, stirring at 100 rpm for 15-20 minutes, placing the resultant mixture in an ultrasonic disperser, ultrasonically-processing at 300 W and 18-25 degrees C for 8-12 minutes, and maintaining the resultant mixture to room temperature for 35-45 minutes.
