| 摘 要： | 以线性低密度聚乙烯(LLDPE)、高密度聚乙烯(HDPE)、有机改性的蒙脱土(MMT)为主要原料,选用乙烯-醋酸乙烯酯接枝马来酸酐(EVA-g-MAH)作为增容剂,采用熔融插层法制备了线性低密度聚乙烯/高密度聚乙烯/蒙脱土(LLDPE/HDPE/MMT)纳米复合材料。通过X射线衍射(XRD)分析蒙脱土在聚乙烯基体中的分散情况,并研究蒙脱土的含量对其在基体中分散效果的影响。TG实验结果表明,蒙脱土的加入使LLDPE/HDPE/MMT纳米复合材料的热稳定性得到很大的提高。由DSC曲线可以得出,加入蒙脱土的复合材料相比于纯聚合物,其熔点和热分解温度都有很大的提高,提高程度与蒙脱土的含量有关。

| Abstract: | In this work, ethylene-vinyl acetate grafted maleic anhydride (EVA-g-MAH) was chosen as compatibilizer, with LLDPE, HDPE and MMT as the main raw materials. Linear low density polyethylene/high density polyethylene/montmorillonite (LLDPE/HDPE/MMT) nanocomposites were prepared by melt intercalation. The dispersion of montmorillonite in polyethylene matrix was analyzed by X-ray diffraction (XRD). TG results showed that with the addition of montmorillonite the thermal stability of LLDPE/HDPE/MMT nanocomposites has been greatly enhanced. DSC results show that compared with pure polymer montmorillonite composite materials,its melting point and thermal decomposition temperature have greatly improved, the degree of improvement is related to the content of montmorillonite. |
