摘    要:利用静电纺丝法在Q345钢表面制备聚己内酯(PCL)与缓蚀剂二巯基苯并噻唑(MBT)的纳米纤维膜PCL/MBT,然后在其表面旋涂环氧树脂(EP),得到复合涂层。通过电化学阻抗谱技术研究了复合涂层的防腐蚀性能。结果表明:在温度为25 ℃、湿度20%、纺丝电压15 kV、接收距离18 cm、V(氯仿)∶V(丙酮)=2∶3的条件下,PCL质量分数为12%,MBT质量浓度为0.01 g/mL时,静电纺丝得到的纳米纤维表面光滑,粗细均匀。电化学测试结果表明:EP/PCL/MBT复合涂层的防腐性能优于EP/PCL或EP涂层。

Abstract:A nanofiber membrane PCL/MBT with polycaprolactone (PCL) and dithiobisbenzothiazole (MBT) as corrosion inhibitors was prepared on the surface of Q345 steel by electrospinning method. Then the epoxy resin(EP) was spin-coated on the surface of nanofiber membrane to obtain a composite coating. The anticorrosion property of the coating was studied by electrochemical impedance spectrum (EIS) technique. The experiment results indicated that the nanofiber membrane could have smooth surface and uniform thickness under the condition of 12%PCL, 0.01 g/mL MBT at 25 ℃, humidity 20%, spinning voltage 15 kV, receiving distance 18 cm and solvent volume ratio of chloroform∶acetone=2∶3. The results of EIS showed that the corrosion resistance of the EP/PCL/MBT composite coating was better than that of EP/PCL or EP coating.
Keywords:polycaprolactone  nanofibers  electrospinning  epoxy coating  anticorrosion properties
