采用硅烷偶联剂KH-550、KH-560和KH-570对自制的复合纳米导电填料进行改性,制备了3种不同的导电防腐涂料,使用扫描电镜(SEM)、傅里叶变换红外光谱(FT-IR)、体积电阻率/表面电阻率测定仪、划格实验法及铅笔硬度仪等方法对导电涂料进行表征和测试,研究了不同偶联剂对导电涂料理化性能、导电性能以及防腐性能的影响。结果表明:3种硅烷偶联剂处理后的复合导电涂层均具有优良的附着性、高硬度及较低的电阻率,其中KH-560性能最佳,当其含量为3%时涂层的电阻率低至1.9×10~(-4) Ω·m,且带有环氧基的KH560对复合纳米涂层的耐腐蚀性能也有很大的提高。

Three different conductive anti-corrosion coatings were prepared by use of the composite nano conductive fillers modified with silane coupling agent KH-550,KH-560 and KH-570 respectively. And in order to investigate the effect of coupling agents on the conductive anti-corrosion coatings,these coatings were characterized and tested by scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FT-IR),surface and volume resistivity test,cross-cut test and pencil hardness. The results showed that the composite conductive coatings tre...
