- Abstract
This work aims to explore how the cationic UV-curing technology can be applied for corrosion protection of metals. For this purpose, the cationic UV-curing epoxy coating is prepared on the steel surface, with addition of the inhibitor-loaded nanoparticles. To reveal the effect of Ce-loaded SiO2 nanoparticles on the photoinitiated cationic polymerization of epoxy coating, various measurements have been carried out during the UV irradiation, such as the consumption of photoinitiator (triarylsulfonium hexafluoroantimonate salts, TAS), conversion of epoxy groups, gel fraction, swelling degree and relative hardness of coating samples. To evaluate the effect of Ce-loaded SiO2 nanoparticles on mechanical and anticorrosion properties of UV-cured epoxy coating, the impact strength, abrasion resistance, electrochemical impedance spectroscopy and salt spray tests have been carried out and analyzed. The experimental data indicate that the incorporation of Ce-loaded SiO2 nanoparticles into epoxy matrix reduces both the relative hardness, gel fraction and the conversion of TAS photoinitiator and epoxy groups. However, the presence of these nanoparticles increases both impact strength, abrasion resistance and anticorrosion performance of the cationic UV-cured epoxy coating.
