摘要:
纳米纤维可以填补有机涂层中存在的孔隙和微裂纹,并提高其抗腐蚀能力。本文介绍了一种利用静电纺丝方法在Q235碳钢表面制备纳米纤维,并与有机环氧树脂复合,进而提高树脂防腐性能的技术。制备了环氧-纤维复合涂层(PAN-NFs/EP),采用电化学方法以及盐雾实验对复合涂层的防腐性能进行了表征,结果表明嵌入了纳米纤维的环氧复合涂层,其电化学阻抗提高了两个数量级,防腐性能明显提高。本研究对静电纺丝技术在海洋防腐中的应用具有一定的参考价值。

Abstract:
Nanofibers can fill pores and microcracks existing in organic coatings and improve their corrosion resistance. This paper describes a technique for preparing nanofibers on the surface of Q235 carbon steel using electrostatic spinning and compounding them with organic epoxy resin to improve the corrosion resistance of the resin. The spinning process was studied in detail, optimal spinning parameters were selected, and the epoxy-fiber composite coatings (PAN-NFs/EP) were prepared. Electrochemical test methods and salt spray experiments were used to characterize the anticorrosive properties of the composite coatings. The results showed that the electrochemical resistance of the epoxy composite coatings embedded with nanofibers increased by two orders of magnitude and that the anticorrosive properties were significantly improved.
Key words:  Nanofiber  electrospinning  Q235 carbon steel  composite coating  anticorrosive performance
