英文摘要	Purpose The purpose of this paper is to investigate the effect of urea-formaldehyde (UF) nanoparticles on the barrier property and delamination resistance for epoxy coating in a 3.5% NaCl aqueous solution. Design/methodology/approach The UF resin was synthesized via sol-gel method, and UF/epoxy composite coating was prepared through ball-milling process; the microstructure and chemical composition of UF resin were observed using the Fourier transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy; the bonding strength of coating/metal interface was investigated through adhesion test; the mechanical properties of the coatings were studied by tensile tests; and the barrier and corrosion resistance properties were verified using salt spray test, cathodic delamination test and electrochemical impedance spectroscopy measurements. Findings The experimental results indicated that the UF resin presented uniformly dispersed nanoparticles in the epoxy matrix and enhanced the bonding strength of coating/metal interface and then improved the delamination resistance for composite coating, which resulted in the enhancement of the barrier property and corrosion resistance for UF/epoxy composite coating. Originality/value In this paper, an easily prepared blending compounding coating with excellent corrosion resistance property was synthesized via sol-gel method and ball-milling process. The effects of UF nanoparticles on the barrier property and delamination resistance were investigated in detail.
