Embodiment 1
[0045] Weigh 4.2kg of component A1, 4.0kg of component B1, 0.5kg of component C, 1.25kg of component D, 0.02kg of component E, 0.02kg of component F, and 0.01kg of red pigment. The mixer is mixed evenly, and the speed of the high-speed mixer is set at 1400r / min. It is melted and extruded through a twin-screw or single-screw extruder, and the extrusion temperature is 230-300°C; and then pelletized by a granulator to produce pellets. Dry in an oven at 80° C. for 4 hours, and then obtain a sample strip with a thickness of 1.6 mm by injection molding. The temperature of the injection molding machine is set at 270° C., and the injection molding pressure is 70-120 bar.

The mixer is mixed evenly, and the speed of the high-speed mixer is set at 1400r / min. It is melted and extruded through a twin-screw or single-screw extruder, and the extrusion temperature is 230-300°C; and then pelletized by a granulator to produce pellets. Dry in an oven at 80° C. for 4 hours, and then obtain a sample strip with a thickness of 1.6 mm by injection molding. The temperature of the injection molding machine is set at 270° C., and the injection molding pressure is 70-120 bar.
Embodiment 3
[0049] Weigh 3.5kg of component A1, 5.5kg of component B1, 0.2kg of component C, 0.7kg of component D, 0.05kg of component E, 0.04kg of component F, and 0.01kg of red pigment. The mixer is mixed evenly, and the speed of the high-speed mixer is set at 1400r / min. It is melted and extruded through a twin-screw or single-screw extruder, and the extrusion temperature is 230-300°C; and then pelletized by a granulator to produce pellets. Dry in an oven at 80° C. for 4 hours, and then obtain a sample strip with a thickness of 1.6 mm by injection molding. The temperature of the injection molding machine is set at 270° C., and the injection molding pressure is 70-120 bar.
