The invention belongs to the technical field of coatings, and particularly relates to a high-toughness super-weather-resistant powder coating for an aluminum veneer as well as a preparation method and application of the high-toughness super-weather-resistant powder coating. The high-toughness super-weather-resistant powder coating for the aluminum veneer is prepared from the following raw materials: polyester resin, fluorocarbon resin, a curing agent and an auxiliary agent, the curing agent comprises triglycidyl isocyanurate and caprolactam blocked isocyanate; the auxiliary agent comprises a curing accelerator; the curing accelerator comprises an organic tin accelerator and an imidazole accelerator. According to the invention, the polyester resin and the fluorocarbon resin are compounded for use, and the synergistic effect of the curing agent triglycidyl isocyanurate and caprolactam blocked isocyanate and the curing accelerator organic tin accelerator and imidazole accelerator are combined, so that the reaction speed of a coating system can be ensured to be fast enough, and fast curing is realized; in addition, the coating has good high toughness and super weather resistance, and the use requirements of the aluminum veneer are well met.
