▎ 摘　　要

NOVELTY - An acrylic high-elastic waterproof paint comprises modified pure acrylic emulsion, titanium dioxide, fillers and functional additives. The modified pure acrylic emulsion is prepared by adding modified inorganic nanographene capsules. The mass ratio of modified inorganic nanographene capsule to the pure acrylic emulsion is 0.1-0.5. USE - Acrylic high-elastic waterproof paint used for improving toughness of material e.g. metal roof. ADVANTAGE - The acrylic high-elastic waterproof paint has improved anti-aging performance and anti-bacterial performance, washing resistance, weather resistance, self-cleaning property. The modified nanoparticles in the modified inorganic nanographene capsule has excellent hydrophobic property, and is easier to form a chemical bond, so that coating tensile strength, elongation, bonding strength, and weather resistance are improved and has improved heat resistance and aging resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the acrylic high elastic waterproof paint, which involves uniformly-stirring the modified pure acrylic emulsion, titanium dioxide and filler for 20-40 minutes, grinding and filtering the mixture, adding the additives to the mixture and stirring for 10-30 minutes.
