The invention discloses a high-brightness PC outer decorating part for an automobile and a preparation method and application of the high-brightness PC outer decorating part. The PC outer decorating part is composed of synthetic resin, natural resin and ABS plastic raw materials; and the preparation process of the PC outer decorating part comprises the following steps of S1, screening raw materials; S2, cleaning the raw materials; S3, melting the raw materials; S4, performing injection molding; S5, pasting a film; S6, performing paint spraying; and S7, performing packaging, wherein in the stepS1, raw material screening is conducted; specifically, firstly, raw materials for preparing the PC outer decorating part are granulated through a plastic granulator; the plastic granulator comprisesauxiliary equipment, preheating equipment, a cooling device and a control system, and after granulation is completed, corresponding operation is conducted. According to the method, the ABS plastic rawmaterial is added when the raw materials are mixed, wherein the A achieves chemical corrosion resistance, heat resistance and certain surface hardness, the B achieves high elasticity and toughness, the S achieves the processing and forming characteristics of thermoplastic plastics and improves the electrical properties, and the ABS plastic raw material has excellent impact resistance, impact resistance and buffer performance. Moreover, the softness is high.
