Example Embodiment
[0032] Example 1
[0033] (1) Take 30 parts of polycarbonate, 5 parts of polyethylene terephthalate, 7 parts of cyclomethicone, 4 parts of polyvinyl alcohol phosphate and 3 parts of tetrabutyl titanate by weight. , 10 parts of polyethylene, 5 parts of polychlorotrifluoroethylene, 5 parts of glass fiber, 3 parts of silicon dioxide, mix the above ingredients, adjust the temperature to 60℃, and stir for 2h;
[0034] (2) After cooling, the mixture is melted and extruded. The extrusion method is a twin-screw extruder. The temperature of the die in the twin-screw extruder is 180°C, and the temperature in the first zone of the extruder is 190°C. The temperature in the zone is 200°C and the temperature in the three zones is 230°C. After extrusion, the pellets are cut with a pelletizer to prepare polycarbonate polymer materials.
