摘要

Abstract

To prepare a high-performance epoxy resin with excellent thermal

chemical and corrosion stability

diaminoxanthone (DAX) was used to cure diglycidylether of bisphenol-A (DGEBA)-based epoxy resin and blend of DGEBA with functionalized Fe

nanoparticles. Kinetic parameters of curing and thermal degradation of epoxy resin systems were estimated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA)

respectively. The 10% weight loss temperature has been increased from 340 ℃ to 366 ℃ and there was an increase in the char yield from 32.6% to 45.3% for the above systems. The corrosion performance of epoxy coated carbon steel was examined by potentiodynamic polarization

along with immersion test in 1.0 mol/L HCl solution. The results showed that epoxy resins cured with DAX had low tendency to corrosion. In addition

the cured epoxy resin containing 10% Fe

had higher anticorrosion activity than bare DGEBA system. The results showed that functionalized Fe

nanoparticles enhanced char formation and improved the thermal stability as well as anticorrosion activity of the resin.
