摘　　要：介绍了有机硅型聚乙烯加工流变改性剂ＱＬＹ在ＬＬＤＰＥ电缆护套料中的应用。对加有ＱＬＹ的ＬＬＤＰＥ护套料的流变性能进行了试验研究，测试了该护套料的物理机械性能并列举了应用实例。结果表明，在ＬＬＤＰＥ电缆护套料中，加入少量的有机硅型改性剂后，能使熔体的表观粘度下降，从而解决了加工困难的问题，提高了产量，降低了能耗，也解决了电缆涂布中发生的熔体破裂现象，消除了产品外观产生的鲨鱼皮现象，使国产ＬＬＤＰＥ电缆护套料的性能完全达到报批中的国标，满足了电缆产品的质量要求。s The application of silicone processing rheological modifier QLY for PE to LLDPE compound for cable jacket is described in this paper.A test for the rheological property of the LLDPE compound modified by QLY was made,the mechanical properties of the compound was tested,and practical applications were enumerated.The results showed the use of silicone modifier could decrease the melt apparent viscosity of the compound,making the process easy,increasing the production output and lowering energy consumption,overcoming the melt fracture in coating,eliminating shark skin on the appearance of the product,making the property index of the compound come up to target level and meet the quality specification in cable production.
