3．改性增强材料制备方法: PPS改性增强材料对设备没有特殊要求,可采用剪切力较低的双螺杆的挤出机,在280-320℃的温度下进行混炼的挤出。原料的混合顺序也没有特别的限制,对于沸点较低或强度较差的组分最好利用侧加料口在最后两区段加入,可获得更更为优秀的材料。
3. Preparation of modified reinforcing materials: PPS modified reinforcing materials have no special requirements on the equipment. They can be extruded at a temperature of 280-320 ℃ by using a twin-screw extruder with lower shearing force. There is also no particular restriction on the order of mixing of the raw materials. For the components with lower boiling point or poorer strength, it is preferable to use the side feeding port to add the last two sections to obtain more excellent materials.
