摘要:
为降低高能炸药季戊四醇四硝酸酯(PETN)的感度,使用钝感高能炸药1-甲基-2,4-二硝基咪唑(2,4-MDNI)与PETN制备了2,4-MDNI/PETN二元混合体系。通过差示扫描量热法(DSC)研究了不同组分比例的2,4-MDNI/PETN的熔融液化过程,建立了2,4-MDNI/PETN二元混合体系的T-x相图,并得到低共熔物组成。研究了不同升温速率下2,4-MDNI/PETN低共熔物的分解过程,并计算了其热分解反应动力学参数。通过体积收缩率、凝固表面微观形貌等研究了2,4-MDNI/PETN低共熔物的凝固性能。测试了2,4-MDNI、PETN及2,4-MDNI/PETN低共熔物的机械感度,并计算了2,4-MDNI/PETN低共熔物的爆轰参数。结果表明:2,4-MDNI/PETN低共熔物中2,4-MDNI与PETN的摩尔比为71∶29,平均熔融温度116.9 ℃,平均热分解反应温度207.5 ℃,热分解反应活化能167.05 kJ/mol,体积收缩率14.4%,撞击感度32%,摩擦感度0,生成焓-37.1 kJ/mol,理论密度1.732 g/cm3,计算爆速8 031 m/s,爆压27.89 GPa。表明2,4-MDNI的加入可以显著降低PETN的感度,同时保持其较高的能量水平。
Abstract:
In order to reduce the sensitivity of pentaerythritol tetranitrate (PETN), a binary mixed system of 2, 4-MDNI/PETN was prepared with 1-methyl-2, 4-dinitrimidazole (2, 4-MDNI). Melting process of 2, 4-MDNI/PETN with different proportions was studied by DSC. T-xphase diagram of 2, 4-MDNI/PETN binary mixture system was established and the eutectic composition was obtained. Decomposition process of 2, 4-MDNI/PETN eutectic at different heating rates was studied, and the kinetic parameters of thermal decomposition were calculated. Solidification properties of 2, 4-MDNI/PETN eutectic were studied by volume shrinkage and solidification surface morphology. Mechanical sensitivities of 2, 4-MDNI, PETN, and 2, 4-MDNI/PETN eutectic were measured, and the detonation parameters of 2, 4-MDNI/PETN eutectic were calculated. Results show that n(2, 4-MDNI)∶n(PETN) is 71∶29, and the average melting temperature is 116.9 ℃. The average thermal decomposition reaction temperature is 207.5 ℃, and the activation energy of thermal decomposition reaction is 167.05 kJ/mol. Volume shrinkage is 14.4%, impact sensitivity is 32%, and friction sensitivity is 0. Enthalpy of formation is 37.1 kJ/mol, theoretical density is 1.732 g/cm3, calculated detonation velocity is 8 031 m/s, and detonation pressure is 27.89 GPa. In a word, the addition of 2, 4-MDNI can significantly reduce the sensitivity of PETN, and maintain a high energy level.
