摘要: 采用动态热机械分析(DMA)、热重分析(TG)与氧指数测定(LOI)等研究聚磷酸铵(APP)和表面用偶联剂处理过的聚磷酸铵(T-APP)对聚氨酯泡沫阻燃性能和力学性能的影响。结果表明,APP与T-APP都提高了聚氨酯泡沫的燃烧氧指数,后者效果更加明显;当聚磷酸铵用偶联剂处理后,一定程度上改善了加入纯的聚磷酸铵对聚氨酯泡沫的压缩强度和模量的破坏行为。

Abstract: Effect of ammonium polyphosphate with and without coupling agent treatment(T-APP and APP)on the flame retardant and mechanical properties of rigid polyurethane foams(RPUF)were analyzed by means of thermodynamic mechanical analysis(DMA),thermogravimeric analysis(TG)and limited oxygen index(LOI). Results indicated that the addition of APP and T-APP can make an increase in LOI of RPUF,while the T-APP is more effective. The addition of T-APP has improved the compression strength and modulus of RPUF with respect to the compatibility enhancement derived from coupling agent.
