Example Embodiment
[0019] Example 1
[0020] Use the following raw materials in weight ratio:
[0021]
[0022]
[0023] The above-mentioned raw materials with good weight ratio are respectively added to the high mixer and fully mixed for 4 minutes before being discharged. Then the mixed materials are put into the extruder from the main feed port of the twin-screw extruder, and the glass fiber is produced by Side feeder is added. Finally, through water cooling, air drying, and granulation, the composite material is prepared. The temperature during the whole granulation process should be controlled at 180-230℃, and the screw speed should be controlled at 360RPM.
