| 摘 要： | 利用TGA、DSC、热解-电导率仪,研究了文题内容。实验结果说明了溴的引入,使树脂具有良好的阻燃性,当溴含量大于7.63%(wt)时,树脂即能自熄。溴使树脂热解过程成碳倾向增加,分解生成的溴化氢是有效的自由基捕获剂。三氧化二锑和溴同时引入,对阻燃具有协同效应。

| Abstract: | The title content was studied by TGA, DSC, pyrolysis-conductance etc. The results show that the flame retardancy of title resin is improved with the introduction of bromine element and the resin will be selfextinguish when the bromine weight content is more than 7.63%. In the meanwhile, bromine element can increase the char-residue and the HBr created by the pyrolysis of the resin can also act as a radical scavenger. The synergistic action can be found when antimony trioxide was added into the brominated bisphenol-A type resin. |
