摘要：通过改变共混物中乙烯-辛烯共聚物(POE)与马来酸酐接枝POE(POE-g-MAH)的比例,研究了MAH含量对聚酰胺6(PA6)/POE/POE-g-MAH/纳米碳酸钙(nano-CaCO3)复合材料的微观结构和力学性能的影响。结果表明,MAH含量较高时,POE-g-MAH与PA6基体的相容性好,复合材料的冲击强度最高;制备工艺对复合材料的形态及力学性能有很大影响,采用两步法制备的复合材料中nano-CaCO3分散效果更好,其增容作用使弹性体分散相直径增大约100 nm,冲击强度较一步法提高21%。
In this paper, the influence of MAH content on the morphology and mechanical properties of PA6/POE/POE-g-MAH/nano-CaCO3composites was studied by changing the ratio of POE and POE-g-MAH. SEM images showed better compatibility between the PA6 matrix and POE elastomer when the MAH content was higher, resulting in the highest impact strength of the composites. Furthermore, it was found that the morphology and mechanical properties of the composites were greatly affected by the processing method. Nano-particles dispersed well in the matrix when the composites were prepared by a two-step processing method. The size of POE phase was enlarged about 100 nm by the formation of core-shell structure with nano-CaCO3 particles. As a result, the impact strength of the composites made by the two-step method increased 21 % compared with that of the composites by the one-step method.
