摘要

为利用高韧性β-PP制备高性能碳酸钙填充PP复合材料，该文采用负载β-成核剂的纳米碳酸钙（β-CC）、纳米碳酸钙（CC）和微米碳酸钙（WC）填充PP制备βPP复合材料。结晶行为与熔融特性的DSC结果表明，加入CC和WC提高PP结晶温度，β-CC 填充PP复合材料的结晶温度高于CC和WC填充PP，表明β-CC对PP结晶的异相成核作用高于CC和WC。XRD结果表明，CC和WC填充PP复合材料主要形成α-晶，β-CC 填充PP复合材料主要形成β-晶。采用β-CC可制备高β-晶含量的碳酸钙填充PP复合材料。

Abstract

In order to obtain high performance PP composites using high toughness β-PP

the β-PP composites were prepared by PP filled nano-CaCO

(CC) supported β-nucleating agent (β-CC)

CC and micro-CaCO

(MC).The result of differential scanning calorimetry indicated that the crystallization peak temperatures of PP increased by adding MC

the crystallization peak temperatures of β-CC filled PP composites were higher than those of composites filled by MC and CC

and the heterogeneous nucleation of β-CC was higher than those of MC and CC for iPP crystallization. The results on wide-angle X-ray diffraction analysis demonstrated that the MC and CC filled iPP composites mainly formed α-crystal

and the β-CC filled composites mainly formed βcrystal. The β-iPP composites with high filler could be prepared by adding β-CC into iPP matrix.
