摘要
为了提高CL-20基高爆热含铝压装混合炸药配方的成型性能,使用了新的黏结剂体系。通过工艺优化研究,获得了最佳的机械干混工艺条件:混合温度70~85℃,混合时间20~30 min;最佳的压药条件:压药温度85℃、比压3 300 kg/cm^2、保压时间60 min。对新配方的爆热、真空安定性、爆发点和环境适应性进行了测试,结果显示,新配方具有很高的爆热,良好的热安全性、环境适应性和可靠性。新配方密度为2.041 g/cm^3,爆热为8 834.3 J/g。
A new binder system was used to improve the forming performance of CL-20 based aluminized PBX explosive with high detonation heat. Through the study of process optimization, the optimal mechanical dry mixing process condition was obtained as duration of 20-30 min within the temperature range of 70-85 ℃ and the best pressuring operation was confirmed as holding time of 60 minutes at charge temperature of 85 ℃ and under specific pressure of 3 300 kg/cm^2. Detonation heat, vacuum stability, explosion point and environmental adaptability of the new formula were tested. Results show that the new formula has high detonation heat, good thermal safety, environmental adaptability and reliability. Density and detonation heat of the new formula are 2.041 g/cm^3 and 8 834.3 J/g respectively.
