制备了邻苯二甲醚二烯丙酯/蒙脱石纳米复合材料(即DAP/DK1),并研究了该复合材料的热学及力学性能。用X射线衍射(XRD)、透射电子显微镜(TEM)、热重分析(TGA)、静力学测试(ST)及动态热力学分析(DMA)对复合材料微观结构和性能进行了表征。结果表明所制备的复合材料具有有序插层的结构,层间距与有机蒙脱石(DK1)的含量无关,为3.90 nm。当DK1的含量达3%时,弯曲强度及冲击强度达最大值,比纯固化树脂分别提高了36.7%及30.4%,复合材料的热学性能略优于纯固化树脂。
The diallyl phthalate / montmorillonite nanocomposites (DAP / DK1) were prepared and the thermal and mechanical properties of the composites were studied. The microstructures and properties of the composites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), static analysis (ST) and dynamic thermodynamic analysis (DMA) The results show that the prepared composites have an ordered intercalation structure, the interlayer spacing is independent of the content of organic montmorillonite (DK1), which is 3.90 nm. When the content of DK1 reaches 3%, the flexural strength and impact strength reach the maximum, which are respectively 36.7% and 30.4% higher than that of the pure resin. The thermal properties of the composite are slightly better than that of the pure resin.
