Provided in the present invention are a coloured co-extruded PVC material and a use thereof. The coloured co-extruded PVC material comprises the following raw materials in parts by mass: 70-100 parts of a PVC resin, 4.0-7.5 parts of a heat stabilizer, 0-8.0 parts of a processing aid, 0-8.0 parts of a toughener, 0-15 parts of a filler, 0.3-2.0 parts of a lubricating agent, 0.1-1.5 parts of a weather-resistant agent, and 0.1-5.0 parts of a pigment. By utilising the coloured co-extruded PVC material provided in the present invention, surface co-extruded layers with a bright colour, good weather resistance and excellent mechanical properties can be formed in products of different formulation systems, such as hard PVC plastic materials, PVC doors and windows, and the like. |
