高耐磨環(huán)氧樹(shù)脂納米復(fù)合材料的制備及性能

高耐磨環(huán)氧樹(shù)脂納米復(fù)合材料的制備及性能摘要：

本文研究了一種高耐磨環(huán)氧樹(shù)脂納米復(fù)合材料的制備及其性能，該復(fù)合材料是由環(huán)氧樹(shù)脂作為基體材料，通過(guò)摻入不同比例的納米硅粉和納米碳黑而制得。通過(guò)SEM、XRD、FTIR、TGA、DMA、摩擦磨損試驗(yàn)和三點(diǎn)彎曲試驗(yàn)等多種測(cè)試手段對(duì)其進(jìn)行性能測(cè)試。

結(jié)果表明，隨著納米硅粉的含量增加，復(fù)合材料的硬度和模量逐漸提高；隨著納米碳黑的含量增加，復(fù)合材料的導(dǎo)電性逐漸提高。在摩擦磨損測(cè)試中，納米硅粉含量為10%的復(fù)合材料表現(xiàn)出最好的耐磨性能，摩擦系數(shù)與磨損率較低。在三點(diǎn)彎曲測(cè)試中，納米硅粉含量為15%的復(fù)合材料表現(xiàn)出最高的彎曲強(qiáng)度。

因此，本研究表明納米硅粉和納米碳黑可以有效地改善環(huán)氧樹(shù)脂的耐磨性和導(dǎo)電性能。這種高耐磨環(huán)氧樹(shù)脂納米復(fù)合材料可以應(yīng)用于一些需要高強(qiáng)度、高防護(hù)和高導(dǎo)電性能的領(lǐng)域。
