the color film layer comprises a PVC original film layer, an undercoat layer, a surface coating and an ink layer, wherein the PVC original film layer, the undercoat layer, the surface coating and the ink layer are sequentially arranged in a layered manner from bottom to top, the ink layer is printed or digital spray-printed on the upper surface of the surface coating by adopting water-based ink, and the water-based ink is fixed on the coating by adsorbing the undercoat layer and the surface coating;
and after the preparation of the color film layer is finished, the color film layer is overlapped with the base material layer and the wear-resistant layer in a layered manner and integrally formed by hot pressing.
Preferably, after hot press forming, the wear-resistant layer is further coated with a UV protective layer having water resistance, scratch resistance and wear resistance.
Preferably, the main component of the wear-resistant layer is PVC material, and the thickness of the wear-resistant layer is 0.1-0.8mm.
Preferably, the main component of the substrate layer is PVC material, and the thickness of the substrate layer is 1.0-6.0mm.
Preferably, the thickness of the color film layer is 0.05-0.1mm.
