| Résumé : |
The Mannich-like condensation of a cardanol, paraformaldehyde, and N,N′-bis(2-aminoethyl)ethane-1,2-diamine were carried out to synthesize the amine functional benzoxazine (Bnz) resin. The amine functionality of Bnz resin was evaluated by physiochemical methods, and the structure was characterized using Fourier transform infrared and 1H-nuclear magnetic resonance spectroscopy. The added functionality into the Bnz resin backbone was utilized to modify the Bnz resin structure by glycidoxypropyltrimethoxysilane (GPTMS) in various proportions. The results revealed that the silane-modified Bnz coatings have improved mechanical, chemical, and solvent resistance properties as compared to the neat Bnz coating. The gel and water absorption of polyamide-cured coatings also has been evaluated. Furthermore, the cured films have been evaluated for glass transition temperature (Tg) and thermal resistance by differential scanning calorimetry and thermogravimetric analysis, respectively. The corrosion resistance properties were studied by salt spray and electrochemical analysis. It was observed that the highly crosslinked structure of the GPTMS-modified Bnz coatings enhanced the barrier protection to corrosive species. |
