| 摘 要： | 利用纳米CaCO3对聚丙烯（PP）的增强增韧作用，采用合理的成型工艺及设备，挤出成型了性能优越的发泡板材。详细研究了CaCO3粒子对板材力学性能的影响，研究表明：纳米CaCO3粒子的含量接近4％时（相对PP），粒子在基体中的分散良好，复合材料的拉伸强度和冲击强度达到最大值；纳米粒子是否经过表面处理，只对材料冲击强度的影响产生不同效果；微米CaCO3粒子含量小于5％时（相对PP），对板材的性能影响很小，但超过该含量后，板材的性能明显下降。

| Abstract: | Nano-CaCO3/polypropylene (PP) foamed sheet was obtained via extrusion. Effects of nano CaCO3 on mechanical properties were investigated. When the content of nano CaCO3 was near 4 phr, both tensile and impact strength showed a maximum. In contrast, the micro CaCO3 had little effect on the mechanical properties when its content was lower than 5 phr, however, strong negative effect above that. |
