通过傅里叶变换红外光谱仪、差示扫描量热仪、X射线衍射仪研究了熔融挤出温度对聚酰胺(PA)6/LiCl复合材料结晶行为和力学性能的影响。结果表明，熔融挤出温度越高，LiCl与PA6的络合反应程度越大，PA6/LiCl复合材料的结晶不完善程度增大，结晶度减小；随着熔融挤出温度的提高，PA6/LiC复合材料的弯曲强度、拉伸强度均先减小后增大，分别在260℃和240℃时出现最小值90.19 MPa和46.82 MPa，缺口冲击强度则先增大后减小，在250℃时达最大值2.30 kJ/m2。

The effect of melt extrusion temperature on crystallization and mechanical properties of PA6/LiCl composites were investigated by FTIR,DSC and XRD.Results show that the higher the processing temperature,the deeper the complex degree of PA6 and LiCl,at the same time,the crystallinity of PA6/LiCl composites is smaller,the crystal degree is more imperfect.As the extrusion temperature increase,the tensile strength and bending strength of composites decrease firstly and then increase,and they reach the minimum of 46.82 MPa and 90.19 MPa respectively at 240℃and 260℃.The notched impact strength of the composites increase firstly and then decrease,and it reach the maximum of 2.30 kJ/m2 at 250℃.
