摘　　要：利用树脂包覆制备无卤阻燃发泡聚苯乙烯(EPS)保温泡沫材料,在EPS保温泡沫材料中添加磷酸硼(BPO4)和可膨胀石墨(EG),并与聚磷酸铵(APP)协效复配,研究磷-氮-硼协效阻燃体系对EPS的阻燃影响。结果表明,阻燃EPS极限氧指数(LOI)为33.5%,峰值热释放速率(pHRR)为172.01 kW/m^(2),热释放总量(THR)为7.21 MJ/m^(2),分别比纯EPS下降81.56%和88.01%,700℃时残炭率为13.67%,磷-氮-硼协效阻燃体系增加了EPS的阻燃性能。Using resin coating to prepare halogen-free flame retardant foamed polystyrene(EPS)insulation foam material, boron phosphate(BPO4)and expandable graphite(EG)were added into EPS,and the co-effect of EPS with ammonium polyphosphate(APP)was studied.The test results show that the limit oxygen index(LOI)of flame retardant EPS is 33.5%,the peak heat release rate(pHRR)is 172.01 kW/m^(2),and the total heat release(THR)is 7.21 MJ/m^(2),which are 81.56%and 88.01%lower than pure EPS,respectively.The carbon residue rate is 13.67%at 700 ℃,the flame retardant performance of EPS is enhanced by the co-effect flame retardant system of P-N-B.
