The invention discloses a high-specific-gravity ceramic-textured PBT composite material convenient for metal coating and a preparation method thereof, relating to the technical field of material formulation. The high-specific-gravity ceramic-textured PBT composite material convenient for metal coating comprises polybutylene terephthalate, polyethylene terephthalate resin, and inorganic non-metallic materials such as barium sulfate and zirconium oxide, which can improve the surface gloss of injection-molded products and make their specific gravity reach 1.9~2.6 g/cm³, endowing the material with a ceramic texture; thermoplastic polyester elastomer and acrylate toughener are added to obtain a high-specific-gravity plastic with a ceramic texture and rigid-tough balance, and the plastic is also convenient for metal coating through evaporation plating, sputtering and other processes. The preparation method is as follows: adding polyethylene terephthalate to polybutylene terephthalate to fill and mix with inorganic non-metallic materials, pre-mixing uniformly with a high-speed mixer; and performing melt blending, extrusion and granulation in a twin-screw extruder.
