Example Embodiment
[0019] Example 1
[0020] 300 parts of polyphenylene sulfide, 5 parts of lithium chloride, 40 parts of polyethylene oxide, 550 parts of glass fiber, 90 parts of sulfonated styrene-butadiene-styrene copolymer, 9 parts of aluminate coupling agent, After 2 parts of antioxidant 1010 and 4 parts of processing aids are dispersed and mixed by a high-speed mixer, they are melted, mixed, extruded, cooled, dried, pelletized and packaged by a twin-screw extruder. The resulting composite material has a volume resistivity of 4.1×10 9 Ω.cm
[0021] The speed of the high-speed mixer is 2000r / min, and the mixing time is 5-30min. The temperature of each zone of the screw barrel of the twin-screw extruder used is kept at 280-340℃, the main engine speed is 100r / min, and the feeding speed is 40r / min. It is cooled by water and dried at 120℃ with hot air. After the extruded product is fully dried, it is injected with an injection molding machine according to the standard size to form a test standard sa...
