摘　　要：用氧指数(LOI)、TG法研究了2,4,6 三溴苯胺(TBA)对环氧树脂酸酐固化物阻燃耐热性的影响,结果表明TBA有较好的阻燃效果,其与Sb2O3和磷酸三苯酯(TPP)配用时具有协同阻燃效应,且对环氧树脂酸酐固化物的热稳定性影响较小。The influences of 2,4,6-tribromoaniline(TBA) on flame retardancy and thermal stability of cured epoxy resin were studied using oxygen index measurement and thermogravimentry and it showed that the epoxy resin system cured containing TBA had better flame retardancy and TBA displayed the flame-retardation synergism when it was used together with triphenyl phosphate or Sb_2O_3 and showed little influence on the heat resistance of cured resin with an hydride curing agent.
