摘要

为探究聚烯烃弹性体(POE)链结构差异对聚丙烯/聚烯烃弹性体(PP/POE)复合材料结构与性能的影响,选取链段结构不同的POE、滑石粉母粒(Talc)与PP进行熔融共混,制备PP/POE复合材料。采用熔体流动速率测试仪、电子万能试验机、悬臂梁冲击试验机、热重分析仪(TG)、差示扫描量热仪(DSC)、场发射扫描电子显微镜(FESEM)对PP复合材料的结构和性能进行表征。结果表明:与乙烯-1-丁烯共聚物(POE-C4)相比,乙烯-1-辛烯共聚物(POE-C8)在保持PP/POE复合材料拉伸强度的同时,提升了复合材料的韧性。POE链结构的差异对PP/POE复合材料的热稳定性能没有明显影响。

Abstract

In order to investigate the effect of the polyolefin elastomer (POE) chain structure difference on the structure and properties of polypropylene/polyolefin elastomer (PP/POE) composites, POE with different chain structure, talc masterbatch (Talc) and PP were melt blended to prepare PP/POE composites. The structure and properties of PP composites were characterized by a melt flow rate tester, an electronic universal tester, a cantilever impact tester, a thermogravimetric analyzer (TG), a differential scanning calorimeter (DSC) and a field emission scanning electron microscope (FESEM). The results show that compared with an ethylene-1-butene copolymer (POE-C4), an ethylene-1-octene copolymer (POE-C8) not only maintains the tensile strength of PP/POE composites, but also improves the toughness of the composites. The difference in POE chain structure has no obvious effect on the thermal stability of PP/POE composites.
