摘要	使用纳米SiO2作为载体、8-羟基喹啉作为客体制备纳米SiO2/8-羟基喹啉组合物,将其添加到环氧树脂中制备出装载8-羟基喹啉的纳米SiO2/环氧涂层。对其进行盐雾和电化学阻抗谱实验,研究了装载8-羟基喹啉的纳米SiO2/环氧涂层的耐腐蚀机理。结果表明,纳米SiO2/8-羟基喹啉组合物提高了环氧涂层的耐腐蚀性能,添加5%（质量分数）纳米SiO2/8-羟基喹啉组合物的环氧涂层的耐腐蚀性能较优。8-羟基喹啉从纳米SiO2孔道中释放并渗透到涂层与钢基材的界面形成含铁的铬合物膜,阻挡了腐蚀介质的渗入,使Q235钢基体的耐腐蚀性能提高。
其他摘要	Composites of 8-hydroxyquinoline/nano-SiO2 were prepared with nano-SiO2 as carrier and8-hydroxyquinoline as modifier. Then the composistes were blended with epoxy resin to form the nanocomposite epoxy coating. The corrosion performance of the prepared composite coating was investigated by means of salt spray test and electrochemical impedance spectroscopy. Results show that composites of 8-hydroxyquinoline/nano-SiO2 can improve the corrosion resistance of the epoxy coatings, among others the coating with 5%（mass fraction） 8-hydroxyquinoline/nano-SiO2 was the optimal. The relevant mechanism may be ascribed to the fact that 8-hydroxyquinoline could release from pores of nano-SiO2 and then penetrate to the interface coating/steel substrate forming Fe-containing complex, thus improving the corrosion resistance of the steel substrate.
