The invention belongs to a water-based weather-resistant antibacterial coiled material coating and a preparation method thereof. The coating is prepared from the following raw materials: modified polyester resin, amino resin, inorganic polysilazane, a photosensitive material, a tin oxide/graphene nano-composite, nano titanium dioxide, a coupling agent, a stabilizer, an auxiliary agent and water, the modified polyester resin is allylated hydroxyl-terminated polybutadiene modified polyester resin; the amino resin is a mixture of fully methylated amino resin and partially methylated amino resin in a mass ratio of (1-3): 1; the cadmium sulfide and/or germanium sulfide, the tin oxide/graphene nano compound and the nano titanium dioxide form a uniformly dispersed stable system with the modified polyester resin, the amino resin and the inorganic polysilazane through the coupling agent and the stabilizer, and the cured coating shows excellent acid and alkali resistance, water resistance, high and low temperature resi
