摘要
以5-氨基四唑为原料,碱性条件下氧化得到偶氮四唑钾（PZT）.采用红外、元素分析等对其进行了表征,其化合物分子式为C2N10K2·3H2O.热重分析和差示扫描量热分析表明,PZT在315 ～350 K范围内,发生吸热反应,失去结晶水,在539.3 K时,出现最大放热峰.将PZT作为消焰剂用于发射药装药中,在初速912 m·s^-1,膛压279.4 MPa,PZT含量为2％的装药条件下,采用高速摄影和烟箱法测试了枪口烟焰.结果表明,与制式消焰剂硫酸钾相比,PZT可使枪口火焰面积减少71.4％,火焰温度降低400℃,且枪口烟雾较小,具有良好的抑制枪口烟焰效果.
A potassium 5,5＇-azotetrazolate（PZT） was synthesized through alkaline oxidation reaction using 5-aminotetrazole as a starting material. The structure of PZT was characterized by IR and elemental analysis and then the molecular formula C2 N10 K2 · 3H20 was confirmed. Thermogravimetry and differential scanning calorimetry results show that endothermic reaction occurs and PZT loses crystal water from 315 K to 350 K. The maximum exothermic peak appears at 539.3 K. As flame inhibitor used in gun propellant charges at following： initial velocity 912 m ~ s-1 , pressure 279.4 MPa, PZT content 2%, the effects of PZT on muzzle flame and smoke were tested by high speed photography method and a smoke box method. Results show that the flame area decreases by 71.4% and the flame temperature reduces by 400℃ when PZT used instead of the common flame inhibitor K2SO4. The high- nitrogen flame inhibitor PZT has better effect in reducing muzzle flame and smoke than K2SO4.
