Example Embodiment
[0019] Example 1
[0020] Mix the block styrene copolymer, extender oil, polypropylene, olefin thermoplastic elastomer filler, organic matting agent, crosslinking agent, stabilizer and other components in a high-mixer at the following weight percentages for 30 minutes, mix well, and then Mix in a low-speed mixer for 20 minutes. The uniformly mixed material is added to the twin-screw extruder by a metering feeder. The temperature is set at 190℃-230℃, the main engine speed is set at 320rpm / min, and the feeder frequency is set. At 28 Hz. The mixed raw materials are obtained by high-temperature shearing, melting, plasticizing, mixing, and water ring cutting in a twin-screw extruder.
