[0056] Corresponding to the above nylon 66 material, the embodiment of the present invention also provides a preparation method of nylon 66 material, refer to figure 1 As shown, the method includes the following steps:
[0057] S1: Prepare raw materials according to the following weight percentages:
[0058] PA66 27%~86.7%, the first flash inhibitor 0.1%~1%, the second flash inhibitor 3%~10%, glass fiber 10%~60%, antioxidant 0.1%~1%, lubricant 0.1%~1%;
[0059] S2: After mixing the above PA66, the first flash inhibitor, the second flash inhibitor, antioxidant and lubricant through the mixer, add them to the twin-screw extruder for fusion mixing;
[0060] S3: Add glass fiber through side feeding, and cool the extruded strip through a water tank, wherein the temperature of the cooling water is 15°C to 20°C;
[0061] S4: The nylon 66 material is obtained after pelletizing by a pelletizer, and the rotating speed of the pelletizer is 500rpm-700rpm.
[0062] All the above option...
