Embodiment 1~14
[0055] Table 1 shows the content of each component in the high wear-resistant and high-weather-resistant polyamide compositions of Examples 1-14.
[0056]The preparation method is as follows: uniformly mix the components according to Table 1, then put the mixture into a twin-screw extruder for melt blending, extrusion and granulation to obtain a polyamide composition with high wear resistance and high weather resistance.
[0057] Among them, the screw length-to-diameter ratio of the twin-screw extruder is 40:1, the temperature of the screw barrel is 240-300°C, and the screw speed is 200-550rpm.
[0058] The component content (parts by weight) of the polyamide composition of table 1 embodiment 1~14
