Embodiment 1
[0039] Weigh the raw materials except glass fiber according to the weight ratio in Table 1, mix them evenly and add them to the hopper of the twin-screw extruder, and at the same time feed the glass fiber from the side of the extruder, and then melt extrusion, water cooling, and air knife cooling , granulation and homogenization to obtain an antibacterial PPS composite material with low warpage and low flash. The processing technology is as follows: the temperature of the first zone of the twin-screw extruder is 250-260°C, the temperature of the second zone is 275-285°C, the temperature of the third zone is 280-290°C, the temperature of the fourth zone is 280-290°C, the temperature of the fifth zone is 265-275°C, and the temperature of the sixth zone is 265-275°C. Zone temperature 265~275℃, zone 7 temperature 255~265℃, zone 8 temperature 245~255℃, head temperature 285~295℃; screw speed 400~450r / min, vacuum: ≥600mmHg, cooling water temperature: 40~ 60°C, drying time 2~4h, dryin...
