摘要
为研究高能钝感材料2,4,6-三氨基-3,5-二硝基吡啶~(-1)-氧化物(TANPyO)与氟橡胶造型粉的热分解特性和热稳定性,利用绝热加速量热仪(ARC)测试其在绝热条件下的热分解过程,获得了热分解的升温速率、温度和压力等随时间的变化关系以及升温速率、压力随温度的变化等曲线。结果表明:绝热分解开始之前有一个缓慢的吸热升温过程,绝热分解过程有三个放热反应,其中第一次分解放热反应升温速率升降幅度较大为主要的热分解阶段。根据ARC升温速率方程和Arrhenius公式以及绝热分解的测试数据计算出表观活化能、指前因子和反应热等参数分别为396.47 k J·mol~(-1)、2.366×1032min~(-1)和1075.04J·g~(-1)。造型粉初始分解温度高达260.7℃,具有良好的热稳定性。
In order to investigate thermal decomposition properties and thermal stability of high energy and insensitive energy materials 2,4,6-triamino-3,5-dinitropyridine-1-oxide(TANPyO) and fluorine rubber moulding powder,adiabatic thermal decomposition of moulding powder was studied by accelerating rate calorimeter.Temperature rise rate,temperature and pressure versus time curves,pressure and temperature rise rate versus temperature curves,pressure and temperature conversion rate versus time curves,and temperature versus TMR(time to maximum rate) curve were obtained respectively.Investigation results of thermal decomposition indicated that there was a slow endothermic rising temperature process before adiabatic thermal decomposition of moulding powder,moulding powder started to decomposition at 260.7℃,its adiabatic thermal decomposition was divided into three stages,the temperature rise rate seldom changed obviously in the second and third stage,the first stage was most important in three ones,in that the temperature rise rate had obvious change.With the help of the temperature rise rate and Ahhenius equation and the test data of adiabatic thermal decomposition of moulding powder,kinetic and thermodynamic parameters had been calculated,apparent activation energy,pre-exponential factor and reaction heat were 396.47 k J·mol~(-1)、2.366×1032min~(-1) and 1075.04J·g~(-1),respectively.According to measurement data,the decomposition history and safety of moulding powder were analysed,the test results showed that initial decomposition temperature of moulding powder was higher than 260.7℃,and possessed better thermal stability.
