Water-based super anticorrosive coating for aluminum fin of air conditioner heat exchanger and preparation method thereof

The invention discloses a water-based super anticorrosive coating for an aluminum fin of an air conditioner heat exchanger and a preparation method thereof, and relates to the technical field of anticorrosive coatings. The preparation method comprises the following steps: uniformly dispersing styryltrimethoxysilane modified graphene oxide (GO) into an acrylic monomer in an in-situ polymerization form; taking an active group on the surface as an initiating substance, obtaining the graphene oxide/water-soluble acrylic resin by polymerizing acrylic monomers on the surface of the graphene oxide/water-soluble acrylic resin and is used as a base material to prepare the water-based super-anticorrosive coating, wherein the water-based super-anticorrosive coating comprises the following components:the graphene oxide/water-soluble acrylic resin, amino resin, corrosion-resistant powder, carbon black, anti-settling powder, a coating additive and deionized water. The water-based super anticorrosive coating prepared by the
