| Résumé : |
The changes in fire-resistive coatings during the aging process were studied. XPS results proved that the hydrophilic components in fire-resistive coatings migrated from the inside to the outside of the coating in the presence of moisture. This migration behavior changed the compositions and distributions in the coating. The changes of components weakened the intumescent performances of the coating. SEM observations showed that the aging process affected the forming of the foam structure, causing nonuniform distribution of the cells. The thermal stability of the coatings decreased during the aging time. TGA results indicated that the migration behavior also reduced the cooperation between the coating components. XRD spectra showed that less TiP2O7 was produced in the char layer after the aging tests, which would reduce the chemical strength of the char layer and the anti-ablation stability under high temperature. EDS results showed that the anti-oxidation property of the coating was also damaged by the aging test. |
