摘　　要：本文介绍有机硅树脂型聚乙烯加工流变改性剂(简称QLY树脂)对国产LLDPE(牌号DFDA7042)流变性能的影响,其改善效果在Brabender流变仪上得到证实,仅加入0.5%便可节约塑化能15.7%,节约挤出加工能耗33.3%。增加挤出加工量107.8%。在LLDPE中加入此改性剂后,熔体粘度下降明显,熔体仍呈假塑性流体特征。Effects of a new silicone resin rheotogy modifier for PE processing(QLY resin) on theology property of riative — made LLDPE (tradename DFDA—7042) were reported. The modifying effects were confirmed using a Brabender Rheometer. The plasticizing energy loss decreased by 15.7%, the extrusion energy loss decreased by 33.5% and the extrudate output increased by 107.8%, when 5% of the modifier was added. when LLDPE was mixed with the modifier the melt viscosity of the blend decreased clearly, but the melt still remained pseudoplasticity.
