摘要: 采用熔融挤出的方法,制备了PA6/CaCl2复合材料,研究了熔融挤出温度对PA6/CaCl2复合材料的结晶行为和性能的影响。实验结果表明:随熔融挤出温度的提高,CaCl2与PA6的络合反应程度越大,PA6/CaCl2复合材料的结晶度越小,结晶不完善程度越大,复合材料的粘度越大,熔体流动速率越小。随熔融挤出温度的提高,复合材料的拉伸强度先增大后减小,最后近似趋于定值,冲击强度、弯曲强度随熔融挤出温度的提高总体呈增加趋势。

Abstract: The research focused on the effect of processing temperature on the crystallization process and the properties of the PA6/CaCl2 composites which were prepared through melting extrusion. The results showed that, with the increasing of the processing temperature, the deeper the complex degree of the PA6 and CaCl2 was, the smaller the crystallinity of the PA6/CaCl2 composites was, the more the crystal degree was imperfect; the higher the viscosity of the PA6/CaCl2 composites was, the smaller the melt index was. With the increasing of the processing temperature, the tensile strength of the PA6/CaCl2 composites was increased firstly and then decreased, and finally nearly becomed constant. The Izod impact strength and bending strength with an overall increasing trend when the processing temperature was increased.
