摘　　要：在75 kg/h Spheripol工艺聚丙烯中试装置上,使用茂金属聚丙烯催化剂开发出熔喷专用茂金属聚丙烯MPH1500Y,并进行了熔喷无纺布的加工应用研究,同时对驻极处理的熔喷无纺布性能进行分析。结果表明:MPH1500Y的熔体流动速率约为1500 g/10 min,相对分子质量分布为2.9;MPH1500Y在加工应用过程中可纺性好,喷出、成网、收卷顺利,熔喷无纺布的纤维结构蓬松、形态均匀且细长,添加驻极母粒并经静电驻极处理后有效提高了熔喷无纺布的过滤效率,改善了熔喷无纺布的加速老化性能。The metallocene polypropylene MPH1500Y meltblown special material was developed with metallocene polypropylene catalyst on a 75 kg/h Spheripol polypropylene pilot plant.The processing application research of meltblown nonwoven fabric was carried out,and the properties of the electret-treated meltblown nonwoven fabric was analyzed.The results show that the melt flow rate of MPH1500Y is about 1500 g/10 min and its molecular weight distribution is 2.9.The meltblown material performs excellently in spinnability,spraying,web formation and winding.The fiber structure of meltblown fabric is fluffy,uniform and slender,and the addition of electret masterbatch effectively improves the filtration efficiency and accelerated aging performance of meltblown nonwoven fabric after electrostatic electret treatment.
