Embodiment 1
[0031] Take by weight percentage polypropylene (A) 69.5%, polypropylene (B) 15%, inorganic filler 10%, elastomer 5%, Irganox 1010 is 0.1%, Igrafos 168 is 0.1%, Negonox DSTP is 0.3%, in Dry mix in a high-speed mixer for 5 minutes, then add to a twin-screw extruder to melt and extrude to granulate. The temperature inside the screw barrel is: 200°C in the first zone, 210°C in the second zone, 210°C in the third zone, and 210°C in the fourth zone. The temperature of the head is 220°C, and the rotational speed of the twin-screw extruder is 400 rpm. After the particles are dried, they are injection molded on an injection molding machine to prepare samples.
