【摘要】 用热重(TG)和差示扫描量热法(DSC)研究了Cu O、Fe2O3、碳黑(CB)、Pb CO3、Bi2O3、(NH4)2Cr2O7对P(BAMO/AMMO)含能粘合剂热分解性能的影响。结果表明:6种催化剂使P(BAMO/AMMO)粘合剂的起始分解温度向低温方向移动,叠氮基团放热分解反应提前,促进了粘合剂放热分解反应,升温速率10℃·min-1时,CB和Pb CO3使粘合剂的起始分解温度分别向低温方向移动8.3℃和24.2℃。Cu O、Fe2O3、Pb CO3、(NH4)2Cr2O7使P(BAMO/AMMO)粘合剂中叠氮基团的表观分解热分别增加0.05,0.09,0.10,0.06 k J·g-1,而CB和Bi2O3使叠氮基团的表观分解热减小。更多还原

【Abstract】 The effect of C u O,Fe2O3,carbon black( CB),Pb CO3,Bi2O3and( NH4)2C r2O7 on the thermal decomposition properties of P( BAMO/AMMO) energetic binder was investigated by TG and DSC.R esults showthat the six burning rate catalysts make the initial decomposition temperature of P( BAMO/AMMO) binder shift downwards and the exothermic decomposition reaction of azide groups advance,and the exothermic decomposition reaction of binder is promoted,in which,CB and Pb CO3 make the initial decomposition temperature of the binder shift 8.3 ℃ and 24.2 ℃ downwards at a heating rate of 10 ℃ ·min- 1,respectively.Cu O,Fe2O3,Pb CO3and( NH4)2C r2O7 make the apparent decomposition heat of azide groups in P( BAMO/AMMO) binder increase by 0.05,0.09,0.10 k J·g- 1and 0.06 k J·g- 1,respectively,whereas CB and Bi2O3 make the apparent decomposition heat of azide groups decrease.更多还原
