▎ 摘　　要

NOVELTY - Graphene modified photovoltaic roof high molecular waterproof paint comprises liquid material and powder material, where liquid material consists of 75-90 pts. wt. polymer emulsion, 0.4-1.5 pts. wt. additives, 0.8-1.5 pts. wt. modifier, 0.05-0.2 pts. wt. surfactant, 0.2-0.5 pts. wt. thickening agent and 5-18 pts. wt. water, the polymer emulsion is 20-50 pts. wt. vinyl acetate emulsion, 20-40 pts. wt. pure acrylic emulsion or 30-50 pts. wt. styrene-acrylic emulsion, the auxiliary agent is 0.1-0.3 pts. wt. dispersant, 0.2-0.6 pts. wt. defoamer, 0.1-0.3 pts. wt. bactericide or 0.2-0.4 pts. wt. wetting agent;, the modifier is 0.5-1 pts. wt. dibutyl ester, 0.5-1 pts. wt. dioctyl ester, 0.01-0.1 pts. wt. graphene oxide or 0.01-0.1 pts. wt. single-layer graphene, the surfactant is 0.05-0.15 pts. wt. silane coupling agent and/or 0.05-0.15 pts. wt. phthalate coupling agent. USE - Used as graphene modified photovoltaic roof high molecular waterproof paint. ADVANTAGE - The graphene modified photovoltaic roof macromolecule waterproof paint effectively reduces the water-proof film molecular gap, ensures the waterproof function and reduces the sunlight, acid rain and so on to the aging rate of the waterproof film layer, at the same time, improves the leveling performance after coating, realizes self-leveling of waterproof coating to the metal embedded part and the concrete gap and under the gravity action of the high density material, self-filling the gap, avoids the gap between the embedded part, and the roof base layer, resulting in water seepage.
