▎ 摘　　要

NOVELTY - Coating comprises component A and component B in mass ratio of 1-2:1, where the component A includes 45-60 pts. wt. zinc powder, 8-15 pts. wt. curing agent, 0.1-0.3 pts. wt. defoamer, 0.1-0.4 pts. wt. dispersant, 0.5-2 pts. wt. filler, and 12-20 pts. wt. solvent, and the component B includes 50-65 pts. wt. silicone modified epoxy resin emulsion, and 3-6 pts. wt. polyaniline grafted graphene oxide. USE - The coating is useful for wall decoration. ADVANTAGE - The coating: is hyperbranched, and rich in epoxy zinc; and has good flexibility, adhesion, salt spray resistance, water resistance and impact resistance, improved storage stability and corrosion resistance, excellent mechanical properties and prolonged service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing coating, comprising (i) mixing zinc powder, curing agent, defoamer, dispersant, filler and solvent to obtain component A, (ii) mixing silicone modified epoxy resin emulsion and polyaniline grafted graphene oxide to obtain component B, and (iii) mixing component A and component B to obtain hyperbranched epoxy zinc-rich coating.
