含退役双基发射药的低爆速炸药的研究

Development of A Low Detonation Velocity Explosive Containing Double-base Propellant

研究了一种含双基发射药的低爆速炸药.这种炸药以双基发射药作为敏化剂,以硝酸铵作为氧化剂,二者混合后形成低爆速炸药.炸药由质量分数为7 5 % - 8 0 % 的硝酸铵、1 5 % - 2 2 % 的双基发射药、1 % - 5 % 的密度调节剂和1 % - 3 % 的工艺添加剂组成.试验表明,在低爆速炸药中,随双基发射药质量分数的不同,可制备出满足不同需求的低爆速炸药产品.产品密度控制在0. 76 - 1.02g/cm^3 之间,爆速在1 500 - 2 200 m / s 之间,猛度在8.8 - 9 . 7 m m 之间,殉爆距离达到4 c m .分析探讨了双基发射药的含量、粒度、密度、直径等对爆速的影响.

A low detonation velocity explosive containing double-base propellant was developed by mixing the doublebase propellant as a sensitizer with ammonium nitrate as an oxidant. The explosive contains( mass fraction) 75%-80%ammonium nitrate,15%-22% double-base propellant,1%-5% density modifier and 1%-3% process additives. Testing results show that a series of low detonation velocity explosives could be produced to meet with various product requirements by changing the mass fraction of double-base propellant. Production control can be well realized within a density range of0. 76-1. 02 g / cm3,a detonation velocity range of 1500-2200 m/s,a brisance range of 8. 8-9. 7 mm,and a sympathetic detonation distance up to 4 cm. The influence on detonation velocity was analyzed and discussed due to the variations in content,granularity,density and diameter of double-base propellants.
