Embodiment 1
[0086] A kind of aliphatic polyamide compound that is used for environmental protection electroplating, comprises following raw material by weight percentage (raw material gross weight 10KG):
[0087] PA6 89.5%,
[0088] TPE 10%,
[0089] SEED 0.5%.
[0090] The above-mentioned preparation method of the aliphatic polyamide composite for environmental protection electroplating comprises the following steps:
[0091] (1) PA6 and TPE are added to the twin-screw extruder through the main feeder to carry out melt polymerization, and the strands are cut into pellets to obtain the blend, which is set aside;
[0092] (2) The blend obtained in step (1) and SEED are added to the twin-screw extruder through the main feeder. After mixing, the temperature is controlled at 235°C for melt extrusion, pelletizing, and the twin-screw speed is 300 RPM, promptly obtains the polyamide compound of the present invention.
