高耐磨环氧树脂纳米复合材料的制备及性能

高耐磨环氧树脂纳米复合材料的制备及性能摘要：

本文研究了一种高耐磨环氧树脂纳米复合材料的制备及其性能，该复合材料是由环氧树脂作为基体材料，通过掺入不同比例的纳米硅粉和纳米碳黑而制得。通过SEM、XRD、FTIR、TGA、DMA、摩擦磨损试验和三点弯曲试验等多种测试手段对其进行性能测试。

结果表明，随着纳米硅粉的含量增加，复合材料的硬度和模量逐渐提高；随着纳米碳黑的含量增加，复合材料的导电性逐渐提高。在摩擦磨损测试中，纳米硅粉含量为10%的复合材料表现出最好的耐磨性能，摩擦系数与磨损率较低。在三点弯曲测试中，纳米硅粉含量为15%的复合材料表现出最高的弯曲强度。

因此，本研究表明纳米硅粉和纳米碳黑可以有效地改善环氧树脂的耐磨性和导电性能。这种高耐磨环氧树脂纳米复合材料可以应用于一些需要高强度、高防护和高导电性能的领域。
