▎ 摘　　要

NOVELTY - High-temperature resistant and anticorrosive aqueous coating comprises 70-80 pts. wt. epoxy modified silicon boron resin emulsion, 40-60 pts. wt. vinyl modified epoxy ester resin, 1-5 pts. wt. composite anticorrosive pigment, 6-10 pts. wt. crosslinking agent, 1-5 pts. wt. dispersant, 2-4 pts. wt. wetting agent, 1-2 pts. wt. defoaming agent and 100-130 pts. wt. deionized water, where the composite anticorrosive pigment comprises a hydroxyl-terminated hyperbranched poly(amine-ester) modified graphene oxide/nano-aluminum phosphate composite anticorrosive pigment. USE - High-temperature resistant and anticorrosive aqueous coating. ADVANTAGE - The aqueous coating has excellent high-temperature resistance, anti-corrosion effect, adhesion, high-hardness and simple preparation process and is cost-effective. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the aqueous coating, involving (2a) mixing and dispersing epoxy modified silicon boron resin emulsion, vinyl modified epoxy ester resin and deionized water, adding crosslinking agent and uniformly mixing to obtain a first mixture and (2b) adding composite anticorrosion pigment, dispersant and wetting agent to the first mixture, evenly mixing and dispersing, adding defoaming agent and stirring to obtain the product.
