▎ 摘　　要

NOVELTY - Aqueous epoxy zinc-rich coating based on graphene with good dispersibility comprises component-A epoxy resin graphene emulsion and component-B curing agent zinc powder slurry. The component-A epoxy resin graphene emulsion contains a modified dispersant. The main chain of the macromolecule of the modified dispersant is helical, and the main chain of the macromolecule is circumferentially distributed with oleophilic groups and hydrophilic groups. USE - Used as aqueous epoxy zinc-rich coating based on graphene with good dispersibility. ADVANTAGE - The coating ensures the dispersibility of graphene, which has better film-forming properties than traditional coatings, and has strong density, uniform graphene dispersion, good coating fluidity, good film layer corrosion resistance, strong coating adhesion and good mechanical properties.
