▎ 摘　　要

NOVELTY - Nano-ceramic super-corrosion-resistant aqueous coating comprises 1-5 %mass modified graphene, 1-3 %mass silane coupling agent, 15-20 %mass filler, 2-5 %mass aqueous resin, 30-50 %mass nano-ceramic, 0.5-1 %mass additive and remaining of water. USE - Aqueous coating useful in surface of metal material (claimed). ADVANTAGE - The aqueous coating prevents physical contact between adjacent pigments and fillers to greatest extent, improves the dispersion effect of pigments and fillers in anticorrosive coatings, fills the pinholes formed between pigments, fillers and film-forming resin interface, and has improved comprehensive performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the aqueous coating, involving uniformly stirring above-mentioned components, and grinding the components to particle size of 0.5-10 mu m to obtain aqueous coating.
