摘　　要：利用膨胀型阻燃剂FP2200S,对TPO防水卷材进行阻燃处理,研究FP2200S对卷材的阻燃、吸水率和力学性能的影响。利用极限氧指数(LOI)仪、垂直燃烧(UL 94)仪、热重分析(TGA)仪对阻燃PP的燃烧性能进行测试,结果表明,当阻燃剂添加量为20%时,TPO/FP2200S体系可以达到UL 94 V-0级别,氧指数可以达到32.5%,阻燃性能明显提高,熔滴现象有明显改善。热重分析(TGA)结果表明,经FP2200S处理后,TPO材料的热稳定性显著提高,800℃的残炭量显著增加。在70℃水浴中浸泡168 h后,TPO/20FP2200S的吸水率为4.3%,仍符合使用标准。The flame retardant treatment of TPO waterproofing membrane was carried out by using the intumescent flame retardant FP2200S.The effect of adding FP2200S on the flame retardancy,water absorption and mechanical properties of the coil was studied.The flame retardant PP was tested by the Limiting Oxygen Index(LOI),Vertical Combustion(UL 94)and Thermogravimetric Analysis(TGA).The results showed that when the flame retardant was added at 20%,TPO/FP2200S the system could reach UL 94 V-0 level,the oxygen index reaches 32.5%,the flame retardant performance was obviously improved,and the droplet drop phenomenon was also obviously improved.Thermogravimetric analysis(TGA)showed that the thermal stability of the TPO material was significantly improved after treatment with FP2200S,and the amount of carbon residue at 800℃increased significantly.After immersion in hot water at 70℃for 168 h,the water absorption of TPO/20FP2200S was 4.3%,which still met the standard of use.
