Embodiment 1
[0038] Example 1: Preparation of short glass fiber reinforced polypropylene composite
[0039] Pre-mix other components other than chopped glass fiber, place the uniformly mixed material in the main feeding port of the twin-screw extruder, put the chopped glass fiber into the side feeding machine from the side feeding port, and melt and extrude. The pelletizing of the die surface under water was carried out to prepare the short glass fiber reinforced polypropylene composite material.
[0040] The side feeder has a length-to-diameter ratio of 8:1, a speed setting of 200rpm, and a heating function. The twin-screw extruder adopts a special screw element and screw combination, and the glass fiber dispersion area is a large-lead, non-meshing screw element. For specific parameters, see figure 1 (purchased from Sichuan Zhongzhuang Technology Co., Ltd.).
[0041] The melt extrusion process parameters are set as follows: the temperature of the first zone of the host machine is 140°C,...
