摘　　要：采用两步法制备了硅烷交联聚乙烯(PE)电力电缆绝缘料。以双螺杆挤出机为反应器,以低密度聚乙烯(LDPE)和线型低密度聚乙烯(LLDPE)为基础树脂,考察了影响PE接枝交联的主要因素(如基础树脂的配比,交联剂的用量及种类,引发剂、抗氧剂的用量等),得出了具有良好性能的硅烷交联PE电力电缆绝缘料的配方(质量份数)LDPE为85.00phr,LLDPE为15.00phr,硅烷W为0.60phr,硅烷Q为1.40phr,引发剂为0.12phr,抗氧剂为0.20phr。A two-step process for preparing silane-crosslinked polyethylene （PE） insulant for power cable was developed in this paper. With a twin screw extruder as reactor and low density polyethylene （LDPE） and linear low density polyethylene （LDPE） as basic resin, the main factors affecting gaffing and crosslinking of PE were examined, including ratio of basic resin, variety and dosage of crosslinking agent, initiator and antioxidant content, etc.. A recipe for preparing silane-crosslinked PE insulant for power cable was selected as follows： LDPE 85.00 phr, LLDPE 15.00 phr, silane W 0.60 phr, silane Q 1.40 phr, initiator 0.12 phr and antioxidant 0.20 phr, in mass share.
