| Popis: | Current research on flame-retardant coatings explores alternatives to halogen-based products. Reactive compounds based on phosphorous and silicon were synthesized and cooperated in epoxy acrylate oligomers to form UV-curable flame-retardant wood coatings. FTIR, 1H NMR, hydroxyl and iodine values confirmed successful synthesis of these products. The effect of the varying proportion of the synthesized compounds on the mechanical, chemical and thermal properties of photopolymerized coatings was investigated. Further, the efficacy of flame retardants was estimated by limiting oxygen index and UL-94 vertical burning test. The synergistic behavior between silicon and phosphorous resulted in an optimum formulation giving an LOI of 24 and VTM-0. |
