Abstract
A phosphoramidic acid/inorganic hybridized nanocomposite flame retardant was prepared and characterized for application to polyurethane artificial leather. Three ceramics were prepared using the pursed wire evaporation method. Aluminum was selected as a ceramic flame retardant, considering its flame retardant synergy effects with phosphoramidic acid-based flame retardants. The surface of the Al ceramic flame retardant was functionalized by condensation reaction with silane coupling agents, followed by mixing with the phosphoramidic acid-based flame retardant, to produce a phosphoramidic acid/inorganic hybridized nanocomposite flame retardant. The surface functionalization of the Al ceramic flame retardant was confirmed by SEM-EDS. Particle size reduction to a lower range was achieved by the addition of a dispersing agent. The results of hydrolysis, solubility, and fire retardant tests indicated that the prepared phosphoramidic acid/inorganic hybridized nanocomposite flame retardant had adequate flame retardancy and overall properties for the manufacture of polyurethane artificial leather.
