Abstract

The microrheological phenomenon of kaolin-filled polypropylene (kaolin/PP) composites was investigated for the first time. The microviscosity of kaolin/PP composites was studied by changing the melt temperature and shear rate. Then, injection moulding experiments of rectangular microgrooves with different aspect ratios using kaolin/PP composites and mechanical property tests of the samples were carried out. The results showed that with increasing kaolin content, the microviscosity of the kaolin/PP composites gradually increases. The shear rate had the greatest influence on the microviscosity, and the kaolin content had the least influence. When the aspect ratio of rectangular microgrooves is small, with an increasing kaolin content, the microgroove filling rate increases, and the microstructured sample geometric shape replication effect is good; however, when the aspect ratio reaches 10:1, the microgroove filling rate decreases with an increasing kaolin content. The microstructured sample geometric shape replication effect is also poor, and size effects appear. Different factors control the microrheological morphology of composites with different aspect ratios, including the shear deformation and viscous flow of composites. The increase in kaolin content leads to a decrease in the friction coefficient and an increase in the wear resistance of the composites. We concluded that the best composite formulation for kaolin/PP composites in microinjection is the 7KL/PP composite with 7% kaolin. When the aspect ratio is 5:1, the reproduction of the microstructured sample geometry is the best, and the comprehensive mechanical properties of the sample are the best.

摘要

首次研究了高岭土填充聚丙烯（高岭土/PP）复合材料的微观流变现象。通过改变熔体温度和剪切速率来研究高岭土/PP 复合材料的微粘度。然后，使用高岭土/PP 复合材料进行了不同纵横比的矩形微槽的注塑成型实验，并对样品进行了机械性能测试。结果表明，随着高岭土含量的增加，高岭土/PP 复合材料的微粘度逐渐增加。剪切速率对微粘度的影响最大，而高岭土含量的影响最小。当矩形微槽的纵横比较小时，随着高岭土含量的增加，微槽填充率增加，微结构样品的几何形状复制效果良好；然而，当纵横比达到 10:1 时，微槽填充率随着高岭土含量的增加而降低。微结构样品的几何形状复制效果也较差，并且出现尺寸效应。不同的因素控制着不同纵横比的复合材料的微观流变形态，包括复合材料的剪切变形和粘性流动。高岭土含量的增加导致复合材料的摩擦系数降低，耐磨性提高。我们得出结论，对于微注塑中的高岭土/PP 复合材料，最佳的复合材料配方是含有 7%高岭土的 7KL/PP 复合材料。当纵横比为 5:1 时，微结构样品的几何形状复制效果最佳，样品的综合机械性能最佳。
