摘要：以蓖麻油为基础多元醇,聚磷酸铵(APP)与次磷酸铝(AHP)复配协同聚氨酯阻燃体系,制备了阻燃聚氨酯密封胶(FRPUS)。研究了APP/AHP阻燃体系对FRPUS阻燃性能、热稳定性能的影响。结果表明,APP与AHP的质量比为5:1,添加量为50%时,FRPUS的极限氧指数(LOI)值达到35.1%,较纯PUS提高74.6%;TGA和热降解动力学表明APP/AHP提高了阻燃体系的热稳定性。
The castor oil （CO） polyol-based flame retardant polyurethane sealant （FRPUS） with ammonium polyphosphate （APP） and aluminum hypophosphite （AHP） as the compounded and synergetic flame retarding system was prepared. The effects of APP/AHP system on the flame retardancy and thermal stability of PUS were investigated. The results showed that when the mass ratio of APP to AHP was 5：1 and the total content of APP/AHP was 50%, the limiting oxygen index （LOI） of FRPUS reached 35.1%, which was increased by 74.6%. TGA and thermal degradation kinetics showed that APP/AHP flame retarding system enhanced the thermal stability of FRPUS.
