几种常用燃速催化剂对 P（BAMO/AMMO）含能粘合剂热分解性能的影响

摘要

The effect of CuO,Fe2 O3 ,carbon black(CB),PbCO3 ,Bi2 O3 and(NH4 )2 Cr2 O7 on the thermal decomposition prop-erties of P( BAMO /AMMO)energetic binder was investigated by TG and DSC. Results show that 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 PbCO3 make the initial decomposition temperature of the binder shift 8. 3 ℃ and 24. 2 ℃ downwards at a heating rate of 10 ℃ ·min -1 , respectively. CuO,Fe2 O3 ,PbCO3 and( NH4 )2 Cr2 O7 make the apparent decomposition heat of azide groups in P( BAMO /AMMO)binder increase by 0. 05,0. 09,0. 10 kJ·g -1 and 0. 06 kJ·g -1 ,respectively,whereas CB and Bi2 O3 make the apparent decomposition heat of azide groups decrease.%用热重（ TG）和差示扫描量热法（ DSC）研究了 CuO、Fe2 O3、碳黑（ CB）、PbCO3、Bi2 O3、（ NH4）2 Cr2 O7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 PbCO3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℃。CuO、Fe2 O3、PbCO3、（NH4）2 Cr2 O7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 kJ·g -1，而 CB 和 Bi2 O3使叠氮基团的表观分解热减小。
