利用动态力学分析方法对聚氯乙烯的动态黏弹性能展开了研究,根据时间-温度等效原理建立了以55 ℃为参考温度的聚氯乙烯动态模量主曲线,利用分数阶Zener模型对动态模量主曲线进行了拟合分析。研究结果表明,时间-温度等效原理适用于描述一定温度范围内小应变情况下聚氯乙烯的动态黏弹性力学行为,且分数阶Zener模型能够较好地描述宽频域范围内聚氯乙烯动态模量随频率的变化规律。给出了WLF方程和Arrhenius方程的适用温度范围。

Based on the dynamic mechanical analysis method,the dynamic viscoelasticity of polyvinyl chloride was discussed.Taking 55 ℃ as the reference temperature,the main dynamic viscoelastic curves of polyvinyl chloride were created and then analyzed by the fractional Zener model.The results show that the dynamic viscoelastic properties of polyvinyl chloride could be described by the time-temperature equivalence principle.And the fractional Zener model is able to depict the relationships between dynamic modulus of polyvinyl chloride and frequency in a...
