Waterborne epoxy zinc-rich coating as well as preparation method and application thereof

The invention provides a waterborne epoxy zinc-rich coating as well as a preparation method and application thereof.The waterborne epoxy zinc-rich coating comprises a component A and a component B. The component A comprises specific parts of waterborne epoxy resin, molecular sieve activation powder, zinc powder, an anti-rust pigment, hollow glass beads, MXene and graphene; the component B comprises a water-based amine curing agent and a flash rust inhibitor in specific parts; by adding the hollow glass beads, the MXene and the graphene into the component A for coordinating and matching, the problem of dispersity of the graphene in the waterborne epoxy zinc-rich coating is effectively solved when the adding amount of zinc powder in the waterborne epoxy zinc-rich coating is reduced; the waterborne epoxy zinc-rich coating with excellent corrosion resistance, water resistance and salt spray resistance is obtained. 本发明提供一种水性环氧富锌涂料及其制备方法和应用，所述水性环氧富锌涂料包括A组分和B组分，所述A组分包括特定份数的水性环氧树脂、分子筛活化粉、锌粉、防锈颜料、空心玻璃微珠、MXene和石墨烯，所述B组
