| 摘 要： | 研究了纳米级CaCO3填充粒状、粉状PP复合材料的力学性能,并用SEM观察纳米级碳酸钙在PP中的分散状态及用SALS分析了其结晶行为。结果表明,粉状PP更有利于纳米级碳酸钙在PP中的分散,并具有更好的加工性能、力学性能。同时纳米级碳酸钙改性PP的SALS图像变得弥散、模糊,PP球晶变得不完善,晶粒更小。

| Abstract: | It studied the mechanical properties of nano-CaCO_3-filled pellet PP composites and nano-CaCO_3-filled powder PP composites, observed the dispersion of nano-CaCO_3 in PP with SEM, and analyzed the crystallization of PP with SALS. The results showed that the dispersion, processability and mechanical properties of nano-CaCO_3-filled powder PP composites were better than those of nano-CaCO_3-filled pellet PP composites. Furthermore, the SALS images of nano-CaCO_3 modified PP became dispersive and fuzzy, the PP spherocrystal became defective and the PP crystallite became smaller. |
