摘要
采用极限氧指数、TG-DTA分析、红外分析及元素组成分析,探讨了两种含磷阻燃剂磷酸酯1#(P1#)和TCP在异氰脲酸酯改性聚氨酯弹性体(IMPUE)中的阻燃机理。研究表明:P1#和TCP阻燃IMPUE,既有气相阻燃机理和凝聚相阻燃机理,又有中断热交换阻燃机理,三者协同发挥阻燃作用。其中P1#以气相阻燃和中断热交换阻燃为主,凝聚相阻燃为辅;TCP以凝聚相阻燃和中断热交换阻燃为主,气相阻燃为辅。
The flame retardant mechanisms of two phosphorated flame retardants P1~# and TCP in isocyanurate-modified polyurethane elastomer (IMPUE) were studied. By limiting oxygen index (LOI),TG-DTA,FTIR and X-ray spectrum. The results show that the flame retardant mechanisms of P1~# and TCP used for IMPUE are the gas phase, condensed phase and discontinuous heat exchange,of which gas phase mechanism and discontinuous heat exchange mechanism were predominant mechanism of P1~# to IMPUE. The condensed phase mechanism and discontinuous heat exchange mechanism were predominant mechanism of TCP to IMPUE.
