摘要
采用高分子钝感剂NA聚酯湿法钝感得到叠氮硝胺和高能硝胺两种钝感发射药,用高温加速长贮寿命试验的方法来研究NA钝感剂在发射药中的迁移性能。利用密闭爆发器和内弹道试验法,对加速长贮前后的两种钝感发射药动、静态燃烧性能进行研究,结果表明,加速长贮前后两种钝感发射药的爆热、p-t曲线及内弹道性能没有明显变化。利用显微红外光谱法测定两种钝感发射药长贮前后NA钝感剂的浓度分布,结果发现浓度分布也没有变化。表明NA钝感剂抗迁移能力强,可以满足叠氮硝胺发射药和高能硝胺发射药的长贮性能要求,用其制得的钝感发射药具有良好的弹道稳定性能。
Two kinds of desensitized propellants 1,5-diazido-3-nitrazapentane（DIANP） propellant and high-energy nitramine propellant） were desensitized with polymer deterrent NA in water medium.The migrations of NA deterrent in two kinds of propellants were investigated by accelerated aging tests,closed-bomb tests and interior ballistic tests respectively.The concentration profiles of deterrent NA in two kinds of propellants before and after long-term storage were studied by FTIR microspectroscopy.Results show that there are not significant changes in the explosion heat,p-t curves,interior ballistic and the concentration profiles.The migration ability of NA deterrent is weak in DIANP and nitramine propellants.The propellants desensitized by polyester NA should be stable in the interior ballistic.
