绿色生物基P/N阻燃剂的制备及其环氧树脂阻燃性能研究
Synthesis of green bio-based phosphorus/nitrogen flame retardant and its flame-retardant performance in epoxy resin
摘要
Abstract
In this study,a sustainable and eco-friendly phosphorus/nitrogen-containing bio-based flame retardant(denoted by PN)was synthesized from phytic acid and nicotinamide,and subsequently incorporated into epoxy resin(EP)com-posites.The results demonstrate that the addition of PN significantly enhances the flame-retardant properties of EP:the peak heat release rate and total heat release were reduced by 41.9%and 34.5%,respectively.Moreover,PN effective-ly suppressed smoke production and the release of toxic gases while promoting the formation of a robust char residue.Mechanistic investigations indicate that PN operates through a dual-mode action-catalyzing the formation of a dense,pro-tective char layer in the condensed phase,and scavenging free radicals while diluting flammable gases in the gas phase.These synergistic effects underscore PN's potential as a high-performance,bio-derived flame retardant,offering a prom-ising pathway toward environmentally benign flame-retardant materials.关键词
