摘要
采用熔融挤出的方法,制备PA6/CaCl2复合材料,研究CaCl2含量对PA6/CaCl2复合材料结构与性能的影响。结果表明:随CaCl2含量的增加,PA6/CaCl2复合材料的结晶度越小,结晶不完善程度越大;复合材料的黏度越大,熔体指数越小。PA6/CaCl2复合材料的拉伸强度,冲击强度随CaCl2含量的增加存在极值现象,弯曲强度随CaCl2含量的增加而增加。
Abstract：PA6/CaCl2 composite were prepared through melting extrusion process and structure and properties of PA6/ CaCl2 composite was studied in term of CaCl2 content. The following results were obtained： with the increasing of the CaCl2 content,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 stronger the viscosity of the PA6/CaCl2 composites was, the smaller the melt index was ;the stronger the flexural strength was. But with the increasing of the CaCl2 content,the tensile strength and the Izod impact strength of the PA6/CaCl2 composites had the extreme point.
