| 摘 要： | 用三聚氰胺-甲醛预聚物对CuO、Al(OH)3、Al2O3进行包覆制得微胶囊阻燃剂。采用热重分析、锥形量热分析研究添加阻燃剂的ABS的热解行为,从热量释放、烟气、CO和CO2排放等参数表征其阻燃性能,并用Kissinger方程计算ABS的动力学参数热解活化能的变化。结果表明,CuO微胶囊处理ABS热解反应活化能升高,阻燃主要在于CuO微胶囊提高了ABS热稳定性;Al(OH)3微胶囊主要通过脱水吸热对抑制发烟量效果明显;Al2O3微胶囊对ABS的热解具有催化成炭作用,使材料的热解活化能大大降低。

| Abstract: | Melamine-formaldehyde resin were used to prepare microcapsules of CuO,Al(OH)3 and Al2O3 which were added into ABS as flame retardants,whose thermal behavior and flame retardance were determined by TG,DTG and CONE.Activation energies for the decomposition of samples were obtained using the method of Kissinger.The date show that activation energy for the decomposition of ABS including CuO microcapsule is increased,and the stability of ABS is increased;Al(OH)3 microcapsule has good effect on suppressing smoke by absorbing heat due to dehydration;Al2O3 microcapsule can catalyze decomposition and carbonization of ABS,lead to much low activation energy. |
