摘　　要：在聚丙烯／蒙脱土(PP／MMT)纳米复合材料的基础上添加受阻胺型阻燃剂制备抗滴落阻燃聚丙烯切片并纺丝。动态粘弹性测试表明,加入质量分数为1％的阻燃剂就极大的增加PP／MMT纳米复合材料在低频下的储能模量,抗滴落阻燃聚丙烯的类固态流体行为更加明显。随着蒙脱土含量的增加,抗滴落阻燃聚丙烯纤维内部的网络结构逐渐完善,对纺丝温度的影响也逐渐加大,需要适当降低纺丝温度,以适应网络结构,达到可纺性要求。Anti-dripping and flame-retardant polypropylene chips can be produced by adding hindered amine flame retardant into polypropylene/montmorillonite （PP/MMT） nano-composite. The dynamic viscoelasticity test showed that the storage modulus of the PP/MMT nano-composite was improved considerably at low frequency when the mass fraction of the flame retardant was 1%, thus the solid-like rheological behavior of anti-dripping and flame-retardant polypropylene became more obvious, The net structure gradually formed inside anti-dripping and flame-retardant polypropylene along with the addition of MMT and had an increasing effect on the spinning temperature. The satisfied spinnability can be achieved by properly decreasing the spinning temperature according to the net structure.
