Embodiment 1
[0029] The preparation raw material of the cold-resistant and high-toughness copolymerized polypropylene plastic consists of the following components:
[0030]
[0031] The preparation method of cold-resistant and high-toughness copolymerized polypropylene plastic includes the following steps and is performed in sequence,
[0032] Step S1, using a mixer to mix copolymerized polypropylene, linear low density polyethylene, EPDM, SEBS, sorbitol, and magnesium oxide activator to obtain a raw material mixture;
[0033] In step S2, the raw material mixture is kneaded and extruded by a twin-screw mixing extruder to obtain plastic wire drawing: the temperature of the twin-screw mixing extruder from the feeding port to the discharging port is as follows: the temperature in the first zone is 330°C, and the temperature in the second zone is 330°C. The zone temperature is 330°C, and the three zone temperature is 330°C.
