| 摘 要： | 用3种蒙脱土(原土、OMMT1、OMMT2)与聚丙烯分别熔融插层复合.经X射线衍射(XRD)分析表明,3种蒙脱土均与聚丙烯成功插层复合,制备出聚丙烯/蒙脱土纳米复合材料.重点研究聚丙烯/蒙脱土纳米复合材料的热氧老化性能.结果表明,在聚丙烯材料中,添加少量蒙脱土不但可以提高材料的力学性能,而且明显改善材料的抗热氧老化性能.对3种PP/MMT复合材料热氧老化样品进行傅立叶红外(FTIR)分析和表面形貌观察,发现蒙脱土片层在聚丙烯中插层复合越充分(乃至剥离),其抗热氧老化效果就越明显.

| Abstract: | Three kinds of montmorillonites(pristine montmorillonites,organic modified montmorillonite 1,organic modified montmorillonite 2) were used to prepare polypropylene/montmorillonite(PP/MMT) nanocomposites by using direct melt intercalation technique.Their X-ray diffraction(XRD) characterizations showed that these montmorillonites could be intercalated with the polypropylene to synthesize PP/MMT nanocomposites successfully.Thermal oxidative aging of PP/MMT nanocomposites was emphatically investigated.The results showed that incorporation of a small amount of montmorillonite not only could enhance mechanical properties but also could improve thermal oxidative aging performance of polymer-matrix dramatically.The results of Fourier transition infrared(FTIR) analysis of and morphology of surface observation on the three kinds of aged samples of PP/MMT nanocomposites showed that sufficient intercalation of the clay particles(exfoliated) was of great benefit to improve thermal oxidative aging performance of polymer-matrix. |
