| Abstract: |
| Objective To study the influence of the amount of aniline trimer on the corrosion resistance of the coating. Methods Epoxy coating was cured by aniline trimer ( AT) and isophorone dianime ( IPD) . The chemical structure of aniline trimer was characterized by IR and NMR. The surface morphology of coating was observed by SEM. The anticorrosion ability of the coating was evaluated by electrochemical method and salt spray test. Results The anticorrosion ability of the coating was improved by the addition of AT, and the anticorrosion ability increased with the increasing AT content. However, curing by solely AT destroyed the structure of the coating which reduced the anticorrosion effect. Conclusion The results demonstrated that the best anticorrosion ability was obtained when the weight ratio of AT / IPD was 4 : 1. |
