Example Embodiment
[0021] Example 1
[0022] (1) Weigh each component raw material according to the following parts by weight:
[0023]
[0024] (2) Mix the above-mentioned raw materials by a high-speed mixer at a high speed of 800-1000rpm, a mixing temperature of 40℃, and mix for 10min; pass the mixture through a twin-screw extruder, and control the temperature of each zone at 260- At 290°C, the modified polyphenylene ether material was obtained by drawing and cutting pellets.
Example Embodiment
[0025] Example 2
[0026] (1) Weigh each component raw material according to the following parts by weight:
[0027]
[0028] (2) Mix the above-mentioned raw materials through a high-speed mixer at high speed, control the speed of the high-mixer to 800-1000rmp, the mixing temperature at 60℃, and mix for 3min; pass the mixture through a twin-screw extruder, and control the temperature in each zone at 240- At 275°C, the extruder was stretched and pelletized to obtain the modified polyphenylene ether material.
