摘要
用HAAKE毛细管流变仪研究了阻燃增强聚对苯二甲酸丁二醇酯/聚对苯二甲酸乙二醇酯(PBT/PET)合金的流变行为,测定了流变曲线及黏流活化能。结果表明:阻燃增强PBT/PET合金熔体为非牛顿假塑性流体,其表观黏度与温度的关系符合Arrhenius方程。
The rheological properties of flame retardant PBT/PET alloy were studied by means of HAAKE rheometer, and the rheological curves and viscous flow activation were also obtained. The results show that： the melt of flame retardant PBT/PET alloy is non-Newtonian pseudoplastic fluid, and the relationship between apparent viscosity of the melt and temperature confirms to Arrhenius equation.
