摘要/Abstract

摘要： 制备了UV固化环氧丙烯酸酯-纳米Al2O3复合涂料. 对纳米复合涂层的硬度、附着力、耐腐蚀性及热稳定性等性能进行了表征，并考察了纳米Al2O3对涂层性能的影响规律. 结果表明，涂层硬度及附着力先随纳米Al2O3添加量增加而提高，添加量为2%时，涂层附着力达1级；添加量为3%时，涂层铅笔硬度达6H；添加量继续增大，涂层硬度及附着力均下降. 对纳米复合涂层的热重分析和电化学阻抗谱分析结果表明，加入纳米Al2O3能提高涂层的热稳定性，但加入未改性纳米Al2O3使涂层的耐腐蚀性下降.

Abstract: UV curable epoxy acrylate-alumina nanocomposite coating was prepared. Its hardness, adhesion, corrosion resistance and thermal stability were characterized. The influences of nano-alumina on properties of coating were examined. The results show that the hardness and adhesion of coating were enhanced with increasing the amount of nano-alumina. When the amount was 2%, its adhesion would reach 1 grade. When the amount was 3%, pencil rigidity of coating would reach 6H. However, further increasing the amount of nano-alumina, its hardness and adhesion were decreased. TGA and EIS analysis results revealed that the addition of unmodified nano-alumina could improve thermal stability of the coating, but militated against corrosion resistance.

Key words: UV curable, nanocomposite, epoxy acrylate, coating
