阻燃添加剂对阻燃聚丙烯的流变性及纤维力学性能的影响

Influences of additives on rheological behavior andmechanical properties of flame-retardant polypropylane

实验研究了阻燃聚丙烯中含有2%、6%、10%阻燃添加剂时对流变性能的影响。结果表明,随阻燃剂的增加熔体的表观粘度下降,并且阻燃纤维的断裂强度也下降。

We investigate the influences of additives, with 2%,6%,and 10% respectively, onthe rheological behavior and mechanical strength of flameretardant polypropylane(PP). Experiments reveal that the apparent viscosity of the melt flameretardant PP decreases with increasing additive. The breaking strength of flameretardant PP fiber decreases with increasing additive.
