| 摘 要： | 分别使用超细碳酸钙(ufCaCO3)和纳米碳酸钙(nano-CaCO3)与尼龙6(PA6)熔融共混后,再与马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH)熔融共混,制备了不同碳酸钙含量的PA6/CaCO3/POE-g-MAH复合材料,通过扫描电子显微镜(SEM)观察其分散相态的变化,并测试了材料的力学性能.结果表明:在PA6/ufCaCO3/POEg-MAH复合材料中,当ufCaCO3含量较少时(PA6/CaCO3/POE-g-MAH质量比为99/1/25和95/5/23.8),碳酸钙粒子全部存在于弹性体相中;在PA6/nano-CaCO3/POE-g-MAH复合材料中,在nano-CaCO3含量很少时(PA6/nano-CaCO3/POE-g-MAH质量比为99/1/25),碳酸钙粒子才全部存在于弹性体相中;当nano-CaCO3含量增加后,碳酸钙粒子同时存在于弹性体相和基体相中;无论ufCaCO3还是nano-CaCO3,当其进入到弹性体相中都降低复合材料的弹性模量,当其分散于基体相中则提高复合材料的弹性模量;随着碳酸钙的增加,复合材料发生脆-韧转变所需的弹性体量增加;在脆-韧转变区后,碳酸钙和POE-g-MAH对PA6的增韧有显著的协同作用,其因为可能是碳酸钙粒子进入弹性体相所形成的壳-核结构中的填料粒子"滚珠"作用使断裂应变增加. |

| Abstract: | Nylon6(PA6)/CaCO3/POE-g-MAH composites with different contents of CaCO3 were prepared by melt blending on Nylon 6(PA6)with ultrafine CaCO3(ulCaCO3) or nano-CaCO3 followed by melt blending with ethylene-octene copolymer grafted maleic anhydride(POE-g-MAH).The Morphology of disperse phase and mechanical properties of the composites was studied.The results showed that all CaCO3 particles were coated with POE-g-MAH in the PA6/ufCaCO3/POE-g-MAH composites when the content of ulCaCO3 was a little(PA6/CaCO3/POE-g-... |
