中文摘要：
以苯基磷酰二氯,对羟基苯甲醛及9,10-二氢-9-氧杂-10-磷杂菲(DOPO)为原料,合成了一种新型含磷阻燃剂——二[4-(次甲基-羟基-磷杂菲)苯氧基]苯基氧化磷(DOPO-PPO),其结构经1H NMR和IR表征。通过TGA和DTG研究了DOPO-PPO的热稳定性,热降解行为及成炭性能。结果表明:DOPO-PPO的起始热分解温度为210℃,在700℃时残炭为30.4%。以环氧树脂为基材,DOPO-PPO为阻燃剂,二氨基二苯硫砜为固化剂,制备了阻燃环氧树脂(3)。通过极限氧指数(LOI)和垂直燃烧(UL-94)测试了3的阻燃性能。结果表明:当DOPOPPO的添加量为12.0%(质量百分数,即312)时,阻燃级别为V-0级,LOI为34.0%。
