The invention belongs to the technical field of imitation metal coatings, and particularly relates to a preparation method of a non-conductive imitation metal coating on the surface of a vehicle logo for an intelligent auxiliary driving sensor. The metal powder and the ceramic powder are adopted for composite powder preparation, the metal ceramic composite film is prepared through vacuum cold spraying, the specific thin thickness of the film can be controlled, the discontinuity of the film is guaranteed, and finally the non-conductivity of the film is improved. And through hot isostatic pressing, the hardness and compactness of the film are improved, and the durability of the film is further improved. The finally obtained film has metallic luster and high electromagnetic wave permeability, and the coating film is high in preparation efficiency, simple and convenient in process and low in operation difficulty.
