摘要
在双螺杆挤出机上通过原位增容反应挤出制备了聚酰胺6(PA6)/高密度聚乙烯(PE-HD)共混物。通过力学性能测试、扫描电子显微镜观察和Molau实验,研究了PE-HD含量对PA6/PE-HD共混物的力学性能和体系增容作用的影响。结果表明,PE-HD与马来酸酐(MAH)在挤出共混过程中原位生成了PE-HD-g-MAH,其对PA6/PE-HD共混物有较好的增容作用;PA6/PE-HD共混物的力学性能与界面形态均有较大改善,吸水率有所降低。
polyamide 6 （PA6）/high density polyethylene （PE-HD） blends were prepared via in-situ compatibilized reactive extrusion using a twin screw extruder. The reactive compatibilization of PA6/PE-HD blends as well as the effect of content changes of PE-HD on mechanical properties of PA6/PE-HD blends were studied through mechanical property test, SEM, and Molau. The experimental results showed that PE-HD-g-MAH was formed during the blending extrusion, which provided a good compatibilization on PA6/PE-HD blends.. Mechanical property and interracial morphology of PA6/PE-HD blends were improved obviously, meanwhile the water absorption decreased.
