摘要
研究了不同形态纳米级CaCO3改性PP复合材料的力学性能及其对PP球晶形态的影响。结果表明 ,纳米级CaCO3形态不同 ,复合材料力学性能不一样 ,立方形纳米级CaCO3有利于改善复合材料的冲击性能 ,而纤维状纳米级CaCO3则能明显改善材料的拉伸性能。纳米级CaCO3能使PP球晶明显的细化 。
The mechanical properties and crystal morphology of composite with the different shape nano-CaCO 3 filled PP were studied. The results showed that the impact strength of cube-shaped nano-CaCO 3 particle filled PP was better than that of the fibre-shaped nano-CaCO 3 filled PP. While the tensile strength of the fibre-shaped nano-CaCO 3 particle filled PP was better than that of the cube-shaped nano-CaCO 3 filled PP. The crystals could be made more fine and β-form crystals could be formed by using nano-CaCO 3.
