【摘要】 用PDSC研究了添加CL-20(或DNTF或FOX-12)的改性双基推进剂的热分解行为。发现PDSC曲线中CL-20、DNTF推进剂有两个放热峰,第一个为双基黏结剂的分解峰,第二个为CL-20或DNTF的分解峰。FOX-12改性双基推进剂只有一个分解峰,表明FOX-12和双基黏结剂(NC、NG等组分)一起分解。更多还原

【Abstract】 The pressure differential scanning calorimetry (PDSC) was used to investigate the thermal decomposition behavior of CL-20(or DNTF or FOX-12)CMDB propellant. The result indicated that there are two exothermic peaks of CL-20-CMDB or DNTF-CMDB propellant. The first exothermic peak is due to decomposition of the double base binder, and the second exothermic peak is caused by the decomposition of CL-20 or DNTF. There is only one exothermic peak of FOX-12-CMDB propellant, showing that FOX-12 and double base binder(NC and NG,i.e.)are decomposed at the same time.更多还原
