preparation example Construction
[0030] Also provide a kind of preparation method of nylon composite material in one embodiment of the present invention, comprise the steps:
[0031] S110, weighing and drying the raw materials according to the above weight percentage, wherein the drying condition of the nylon resin is 4-8 hours at 80-100°C;
[0032] S120. Evenly mix the dried nylon resin, modified nano boehmite, compatibilizer, lubricant and antioxidant into the hopper of the twin-screw extruder, and feed it in the side of the twin-screw extruder Add chopped glass fiber at the feed port and extrude;
[0033] For example, add the dried nylon resin, modified nano-boehmite, compatibilizer, lubricant and antioxidant into a high-speed mixer and mix for 15-20 minutes to mix the raw materials evenly before adding them to the twin-screw extruder.
[0034] Specifically, the process conditions of the twin-screw extruder are set as follows: the temperature of the first zone is 200-220°C, the temperature of the second z...
Embodiment 1
[0049] Nylon composite material in the embodiment of the present invention 1 comprises the following components in the following weight percentages:
[0050] Nylon 6: 57.4%, chopped glass fiber: 35%, modified nano boehmite: 5%, compatibilizer: 2%, lubricant: 0.3%, antioxidant: 0.3%.
[0051] The preparation method of nylon composite material in the embodiment of the present invention 1, comprises the following steps:
[0052] Nylon 6 was dried at 100°C for 6 hours, and nano-mica was dried at 100°C for 8 hours. Stir the dried nylon 6, modified nano-boehmite, compatibilizer, lubricant, and antioxidant in a high-speed mixer for 3 minutes, then add it to the hopper of the twin-screw extruder, and put it on the side of the twin-screw extruder Add chopped glass fiber to the feed opening. The process conditions of the twin-screw extruder are set as follows: the temperature of the first zone is 200-220°C, the temperature of the second zone is 220-240°C, the temperature of the third ...
Embodiment 2
