摘要:
为探究耐高温相变蜡(PCWAX)改性聚丙烯(PP)的可纺性和加工性能,采用双螺杆挤出机熔融共混制备PCWAX/PP共混物,借助双柱毛细管流变仪和Hauloff牵伸装置对PCWAX/PP功能粒子的拉伸流变性能及热稳定性进行测试分析。结果表明:PCWAX/PP试样为拉伸变稀型流体。试样拉伸应力与拉伸黏度随温度的升高而降低;增大拉伸应变速率有利于降低试样的拉伸黏度与拉伸流动活化能;PCWAX会减弱试样的流动阻力,试样的拉伸应力、拉伸黏度与拉伸流动活化能随着添加剂含量的增大而减小,在180 ℃,5262 s-1的拉伸应变速率下,20%质量分数PCWAX/PP试样的拉伸应力、拉伸黏度与拉伸流动活化能较纯PP分别下降了609%、482%与206%。PCWAX的加入对PP的热稳定性没有影响,但会使得PP的拉伸比与熔体强度发生一定程度的下降。实验结果对相变功能改性聚丙烯的熔体纺丝工艺制定和优化具有一定的参考价值。
