[0037] Correspondingly, the embodiment of the present invention also provides a method for preparing a PC / PBT alloy material, comprising the following steps, such as figure 1 Shown:
[0038] S01. Weighing formula components: weigh each component according to the above-mentioned PC / PBT alloy material formula;
[0039] S02. Preparation of mixed material: mixing each component except glass fiber and special-shaped cross-section glass fiber to form a mixed material, which is added from the main feed;
[0040] S03. Melt extrusion of materials: Add glass fibers and glass fibers with special-shaped cross-sections from the side feeding port for melt extrusion;
[0041] Among them, the specific process of melt extrusion is: the temperature of the first zone is 150±10°C, the temperature of the second zone is 180±10°C, the temperature of the third zone is 225±5°C, the temperature of the fourth zone is 235±5°C, and the temperature of the fifth zone is 245±5°C, the temperature in the six...
