研究了不同种类偶联剂对聚磷酸铵阻燃环氧树脂(EP/APP)体系拉伸强度、燃烧和发烟性能的影响规律.结果表明,钛酸酯和硅烷都能提高EP/APP体系的拉伸强度.从(EP/APP)体系阻燃性能的提高效果看,钛酸酯比硅烷更好,钛酸酯使EP/APP体系的氧指数从26.5提高到30.9,硅烷使EP/APP体系的氧指数从26.5提高到28.7.但硅烷对(EP/APP)体系的抑烟效果好,硅烷可使EP/APP体系的烟密度等级从76.84降到66.85,而钛酸酯使EP/APP体系发烟量加大,烟密度等级从76.84上升到86.41.研究结果表明,偶联剂在改善阻燃材料力学性能的同时,对体系的燃烧和发烟性能有重要影响.

The influence of different coupling agents on the combustion and smoke production of epoxy resin treated with ammonia polyphosphate（EP/APP） system was studied.The results showed that the tensile strength of EP/APP increased when introduced titanate and silane coupling agents,it also indicated that the effect of titanate coupling agent on the flame retardancy of EP/APP was superior to that of silane coupling agent,The LOI of EP/APP increased from 26.5 to 30.9 and 28.7 when incorporated titanate and silane respectively.However,the effect of sil...
