摘要:
以对羟基苯甲醛、9，10-二氢-9-氧杂-10-磷杂菲-10-氧化物（DOPO）和色胺为原料，成功合成了一种新型阻燃剂——对羟基苯甲色胺磷杂菲（PHTD）。并用其对环氧树脂（EP）进行阻燃性能优化。当PHTD的质量分数达到4%时，EP/PHTD热塑材料的阻燃性能达到V1级别，氧指数（LOI）达到29.2%。在锥形量热实验中，PHTD的添加显著降低了材料的热释放量，幅度达到64.2%。此外，用扫描电子显微镜检测锥形量热测试后的残渣，结果表明，当PHTD的质量分数为8%时，EP/PHTD热塑材料燃烧后的残渣的结构为均匀的致密炭层，可以作为隔绝热、氧的屏障。
Abstract:
This work focuses on a novel flame retardant p-hydroxybenzatryptamine phosphaphenanthrene （PHTD） which is synthesized from tryptamine， p-hydroxybenzaldehyde and 9,10-Dihydro-9-oxa-10-phospha -phenanthrene-10-oxide（DOPO）. The addition of PHTD dramatically improves flame retardancy of epoxy resin （EP）. The flame-retardant thermoset EP/PHTD is qualified a UL-94 V-1 rating and possesses the value of 29.2% in limited oxygen index when the mass fraction of PHTD is 4%. Cone calorimeter test indicates that the release of heat decreases by 64.2% due to the introduction of PHTD. The residue after cone calorimeter test was also analyzed by scanning electron microscopy. The result shows when the mass fraction of PHTD is 8%， char residue for EP/PHTD thermoset is homogeneous and compact ，and the cross-linked layer acts as a positive barrier for exchange of heat and oxygen.
