description An aqueous nano zinc-based composite coating, which comprises: an aqueous polyurethane resin, an aqueous epoxy resin, an aqueous silicon-containing resin, zinc powder, nano-silica, a defoaming agent, an emulsifier, a dispersing agent and an adhesion promoter. The coating comprises water as a solvent, saves on a large amount of resources, and does not comprise VOC harmful substances such as benzene, xylene, ethane, and formaldehyde. The coating has an excellent corrosion resistance performance and a good recoating performance, and is radiation resistant. The coating can be obtained by directly stirring without any grinding procedure. The preparation method is simple and reliable. The risk of fire during construction and storage is eliminated, pollution to the atmosphere is reduced and the coating can also be applied in construction as usual in a closed environment. The coating has strong adhesion to a copper surface, strong weather-resistance and simple operation performance. A coating tool can be directly cle
