| 摘 要： | 研究了含 0 .2 5 %β晶型成核剂 (酰胺化合物 )的聚丙烯 Z3 0 S及其纤维的力学性能、晶型结构和微观形态。通过纺丝 -拉伸实验和力学性能测试、广角 X射线衍射分析、SEM观察 ,发现成核改性后生成了β晶型聚丙烯 (K值约为 75 .3 % ) ,抗冲性能大幅度提高。β晶型聚丙烯在纺丝卷绕过程中发生了β晶型→α晶型转变 ,纤维中产生约 10 %微孔隙 ,改性纤维的力学性能有所降低。

| Abstract: | The mechanical properties, crystal structure and morphology of Z30S PP and its fiber modified by 0.25% β crystal form nucleator (amide compound) were studied by spin\|drawing experiments, mechanical property determination, WAXD and SEM. β crystal form PP (K value of about 75.3%) formed after nucleation, and the impact strength was improved significantly. And the β crystal form was transformed into α crystal form during the stage of spinning and winding, then the micropores formed in fibers with void content in order of 10%, with loss somewhat of the mechanical properties of modified fibers. |
