▎ 摘　　要

NOVELTY - Elastic waterproof paint, comprises water, pigment, hydrophobic modified graphene oxide-superfine kaolin, filler, dispersant, thixotropic agent, defoaming agent and pure acrylic emulsion. The hydrophobic modified graphene oxide-superfine kaolin is graphene oxide modified by long-chain alkyl amine, further modified by silane coupling agent, and then reacted with superfine kaolin to obtain the product. USE - The elastic waterproof paint is used for building outer wall coating used in building exterior facade decorative material, wall surface, roof surface, ceiling surface, window surface, and door surface. ADVANTAGE - The hydrophobically modified graphene oxide-superfine kaolin is added in pure acrylic emulsion, which not only improves the mechanical property and elasticity of the coating, but also significantly improves the waterproof performance and anti-cracking performance of coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the elastic waterproof paint, comprising high-speed stirring and dispersing water, pigment, hydrophobic modified graphene oxide-superfine kaolin and filler for 3-5 minutes, adding dispersant, thixotropic agent and defoaming agent, stirring and dispersing at medium speed for 10-15 minutes, adding pure acrylic emulsion, low-speed stirring, and dispersing for 12-20 minutes to obtain the elastic waterproof coating.
