| 摘 要： | 用密炼机制备了马来酸酐接枝PP(MPP)和丙烯酸接枝PP(FPP)增容的nano-CaCO3/PP/PS复合材料,用TGA研究复合材料的热降解行为。结果表明:加入nano-CaCO3有助于提高PP/PS共混物的热稳定性,对于提高复合材料的热稳定性,FPP、MPP与nano-CaCO3不存在协同作用;nano-CaCO3/增容PP/PS共混物复合材料的DTG曲线在400℃~500℃间有两个失重速率峰,分别对应PS和PP的热降解。

| Abstract: | The nano-CaCO_3/PP/PS composites were prepared compatibilized by maleic anhydride grafted PP(MPP) and acrylate acid(FPP) respectively.TGA was used to investigate the thermal decomposition of the composites.Results show that addition of nano-CaCO_3 favors to the improvement of thermal stability of PP/PS blends.FPP and MPP did not coorperate with nano-CaCO_3 to improve the thermal stability of the composites.Thermal stability of the composites depend upon the kind of compatibilizer.The composites prepared by compatibilized blends exhibited maximum weight loss peaks. |
