摘 要:为研制燃气清洁、成气性好、残渣率低的燃气发生剂,开展了基于相稳定硝酸铵(Phase Stabilized Ammonium Nitrate, PSAN)的燃气发生剂的配方筛选及制备工艺研究,并对配方的燃烧温度、成气量、残渣率、火焰形貌及安全性进行测试。结果表明:配方中氧化剂、黏合剂和增塑剂的最佳配比为40%、30%和30%;PSAN/PBT/A3、PSAN/PBT/BuNENA和PSAN/PET/A3三种配方的燃烧温度分别为1 441、1 611、1 309 K,成气量分别为55.2、49.3、57.7 mol/kg,凝聚相质量分数分别为6.75%、7.25%和6.57%;PSAN/PBT/A3燃烧火焰最明亮,PSAN/PBT/BuNENA火焰亮度减小并伴有大量碳烟产生,PSAN/PET/A3燃烧产生大量碳烟且仅含有微弱火焰;PSAN/PBT/A3、PSAN/PBT/BuNENA和PSAN/PET/A3燃气发生剂的撞击感度分别为34.4、21.6和35.8 cm,摩擦感度均较低。To develop gas-generating agents which are clean,high production,and have a low residue rate,the formulation screening and preparation process of gas-generating agents using PSAN were investigated.The combustion temperature,gas production,residue rate,flame morphology and safety of the formulation were tested.The results show that the optimum ratio of oxidant,binder and plasticizer in the formulation is respectively 40%,30%and 30%.The combustion temperatures of PSAN/PBT/A3,PSAN/PBT/BuNENA and PSAN/PET/A3 are respectively 1441 K,1611 K and 1309 K,and the gas production is 55.2 mol·kg-1,49.3 mol·kg-1 and 57.7 mol·kg-1.The condensed phase contents are respectively 6.75%,7.25%and 6.57%.The combustion flame of PSAN/PBT/A3 is the brightest.The flame brightness of PSAN/PBT/BuNENA decreases with a large carbon smoke emission,while the combustion of PSAN/PET/A3 produces a large amount of carbon smoke and contains only a weak flame.The impact sensitivities of PSAN/PBT/A3,PSAN/PBT/BuNENA and PSAN/PET/A3 gas generating agents are respectively 34.4,21.6 and 35.8 cm,and the friction sensitivities are low.
