| 摘 要： | 以聚丁二酸丁二醇酯(PBS)为基材,经十六烷基三甲基溴化铵(CTAB)改性过的纳米蒙脱土为填料,采用熔融共混法,制备了PBS/MMT纳米复合材料,并研究了该复合材料的热稳定性能、力学性能和流变性能等。结果表明:当改性nano-MMT的添加质量分数为5%时,复合材料的熔点约提高了2.55℃,热初始分解温度提高了33℃;当其添加质量分数为3%时,复合材料的拉伸强度提高了9%,断裂伸长率提高了3%,冲击强度提高了23%;复合材料的流变性能比纯PBS的流变性能有一定程度的提高。

| Abstract: | PBS was blended in a twin-screw extruder with nanoscale MMT modified with CTAB to provide PBS/MMT nanocomposite. The heat resistance, mechanical properties and rheological properties of PBS/MMT nanocomposite were studied. The results showed that when PBS was blended with nanoscale MMT modified by 5wt%, the melting point of PBS/MMT nanocomposite increased by about 2.55℃, the initial heat decomposition temperature increased by about 33℃. When PBS was blended with nanoscale MMT modified by 3wt%, the tensile strength of PBS/MMT nanocomposite increased by 9%, break elongating by 3%, impact strength increased by about 23%. Meanwhile, the rheological properties of PBS/MMT nanocomposite increased to certain degree compared with pure PBS. |
