Carbon crystal decorative film with high metallic feeling and preparation method thereof

The invention relates to the technical field of decorative films, in particular to a high-metallic-feeling carbon crystal decorative film and a preparation method thereof.The preparation method comprises the steps that a carbon crystal base film sequentially passes through two sets of shot blasting pipes which are longitudinally and transversely arranged and is subjected to shot blasting treatment, and first groove bodies and second groove bodies which are longitudinally and transversely staggered are formed; then the carbon crystal base film penetrates through a high-pressure air pipe, and blowing is conducted on the outer end of the carbon crystal base film so as to remove residual shots; roller-coating the outer end part of the carbon crystal base film with a metal texture coating, and carrying out drying and curing treatment to form a protective layer; roller coating the inner end part of the carbon crystal base film with an adhesive to form an adhesive layer, and covering the surface of the adhesive laye
