摘　　要：研究了高密度聚乙烯(HDPE)/线性低密度聚乙烯(LLDPE)硅烷接枝交联体系。分析了过氧化二异丙苯(DCP)、乙烯基三乙氧基硅烷(VTES)、加工设备及工艺条件(温度、螺杆转速)对体系熔体流动速率(MFR)和凝胶含量的影响。并用Buss混炼设备制备出高流动性的铝塑复合管硅烷接枝交联PE专用料。The silane grafting and crosslinking system of HDPE/LLDPE blends is studied. The effect of the concentration of DCP and VTES. processing equipments as well as processing parameters( extruder screw temperature and speed) on the melt flow rate ( MFR)of grafted products and gel fraction of crosslinked products were investigated. Ease-processing silane grafting polyethylene produced in Buss extruder is prepared for aluminum-plastics laminated pipe.
