▎ 摘　　要

NOVELTY - Polyacrylate polymer cement-based waterproof coating comprises 80-160 pts. wt. cement, 60-160 pts. wt. modified acrylate polymer emulsion, 20-50 pts. wt. silicon nitride, 20-30 pts. wt. talc, 5-15 pts. wt. antifoaming agent and 2-10 pts. wt. silane coupling agent. USE - The waterproof coating is used for civil outer wall decoration engineering, emulsion paint, elastic paint, stone paint and colourful paint. ADVANTAGE - The coating has excellent bonding strength, anti-alkali floating flower, stain resistance and crack resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the waterproof coating, comprising mixing cement, silicon nitride and talc, dispersing the mixture in graphene oxide modified polyacrylate emulsion and heating to 85°C, adding antifoaming agent and silane coupling agent, stirring and reacting, cooling to room temperature, and obtaining polyacrylate polymer cement-based waterproof coating.
