The invention discloses a self-repairing type low-temperature enamel coating, a low-temperature enamel composite siloxane hydrophobic coating and a preparation method and application thereof.According to the enamel coating, mica sheets and graphene quasi-two-dimensional materials are assembled into a scallop laminated structure, the mechanical property is enhanced, meanwhile, kaolin is used for adsorbing nano rare earth, when the coating is damaged, a matrix can be rapidly passivated, and the self-repairing type low-temperature enamel coating is obtained. The intelligent corrosion inhibition effect is realized; as a primer of the low-temperature enamel composite siloxane hydrophobic coating, the low-temperature enamel composite siloxane hydrophobic coating has good compatibility with a silica sol modified siloxane finish paint, so that the coating comprehensively combines the characteristics of high thermal hardness, high strength, good wear resistance and self-repairing performance of the enamel primer and t
