摘要： 以9,10-二氢-9-氧杂-10-膦酰杂菲-10-氧化物（DOPO）、甲醛和二乙醇胺为原料,强酸性阳离子交换树脂作催化剂,分两步合成了新型反应型阻燃剂9,10-二氢-9氧杂-10-\[N,N-二(羟乙基)氨甲基\]-10-膦杂菲-10-氧化物（DAM-DOPO）,并制备了DAM-DOPO阻燃剂阻燃聚氨酯泡沫（PUF）,采用红外光谱、核磁共振等分析手段对DAM-DOPO进行了表征,同时通过极限氧指数值测定、水平燃烧试验和CAL 117D实验评估了阻燃PUF的阻燃性能。结果表明,合成的DAM-DOPO阻燃剂熔点为165~167 ℃；添加12 份（质量份,下同）DAM-DOPO阻燃的PUF的极限氧指数为26.5 %,阻燃性能通过GB 8410—2006标准和CAL TB 117D实验。

Abstract: A novel reactive flame retardant was synthesized by a twostep procedure from 9,10-dihydro-9-oxa-10-[N, N-bis-(2-hydroxyethylaminomethyl)]-10-phosphaphenanthrene-10-oxide(DAM-DOPO), formaldehyde and diethanolamine, with a strong acid ion exchange resin as a catalyst. The structure of DAM-DOPO was identified by FTIR, 1H-NMR and 31P-NMR. The flame retardant was employed in polyurethane(PUF) and was evaluated using limiting oxygen index, horizontal burning test and CAL 117D. It was found that the melting point of DAM-DOPO was 165~167 ℃. Limited oxygen index of polyurethanes foam(PUF) containing 12 phr DAM-DOPO was 26.5 %. The flame retardancy of PUF passed the CAL TB 117D test and GB 8410—2006.
