Carbon black(CB) was added into poly(ethylene terephthalate)/polyethylene(PET/PE) blend by discretely feeding technology and fiber grade PET/PE/CB conductive master batch with good combined properties was prepared in reciprocating pulsation extruder.

• 采用分离喂料技术在聚对苯二甲酸乙二酯(PET)/聚乙烯(PE)共混物中加入导电炭黑(CB),通过布斯往复式脉动挤出机熔融共混、挤出造粒,制备了综合性能较好的纤维级PET/PE/CB导电母料。
