| 利用热分析仪对四苯基双酚A二磷酸酯(BDP)及BDP/纳米SiO2阻燃PC/ABS进行了TG分析,研究了BDP及其复配体系阻燃PC/ABS的降解过程,在动力学理论模型基础上,求出了阻燃PC/ABS的热力学参数-活化能。实验结果表明,与未阻燃PC/ABS相比,阻燃PC/ABS在600℃残炭率增加,15%BDP阻燃PC/ABS的残炭率由未阻燃的16.55%增加到22.16%,15%BDP/7%SiO2阻燃PC/ABS的残炭率增加到25.24%;BDP及其复配体系阻燃PC/ABS活化能显著提高,15%BDP阻燃PC/ABS的活化能由未阻燃的91.55kJ.mol-1提高到143.83kJ.mol-1,15%BDP/7%SiO2阻燃PC/ABS的活化能提高到254.08kJ.mol-1,体系耐热性能好,阻燃效果明显,复配体系阻燃效果进一步提高。 |

| TG curves of bisphenol A diphosphate(BDP) and BDP/ SiO2 flame-retarded PC/ABS resins are analyzed using thermal analytical apparatus and their pyrolysis courses are studied.Based on the analysis of academic model of thermodynamics,the sthermodynamics parameter-activation energy of flame-retarded PC/ABS are obtained from thermal analytical data.The results show that because of the addition of retardants,char formation at 600℃ of flame-retarded PC/ABS increased,15%BDP/PC/ABS increased from 16.55% to 22.16%,15%BDP/7% SiO2 /PC/ABS increased to 25.24%.The active energy of flame-retarded PC/ABS obviously increases,15%BDP/PC/ABS increased from 91.55kJ·mol-1 to 143.83kJ·mol-1,15%BDP/7% SiO2 /PC/ABS increased to 254.08kJ·mol-1.And both its thermal stability and heat-resistant have been greatly improved. |
