摘　　要：应用差热扫描量热分析仪,测量了3种粒径硅藻土填充聚丙烯(PP)复合材料的结晶性能,以考察填料含量和粒径对复合体系结晶性能的影响。结果表明:复合材料的结晶性能随着填料体积分数的增加而下降。当φf为10%时,复合体系的结晶度随着硅藻土粒径的增加而呈二次多项式函数形式变化。The crystallization properties of three kinds of polypropylene composites filled with three different kinds of diatomite were measured respectively by using a differential scanning calorimeter(DSC) to investigate the effects of the content and particles diameter of fillers on the fluidity of the composites.The results showed that the crystallization properties of the composites decreased with the increase of the volume fraction(φ f) of the fillers.When φf was 10 %,the crystalline of the composites changed as a quadratic polynomial function with the increase of diatomite diameter.
