摘　　要：为获得低燃温气体发生剂,利用喷雾干燥法制备5-氨基四唑(5-AT)/NaIO_(4)/CuO复合粒子作为气体发生剂配方。通过扫描电子显微镜对5-AT/NaIO_(4)/CuO复合粒子的复合效果进行表征,用同步热分析仪、氧弹量热仪、热电偶和靶线法分别对5-AT/NaIO_(4)/CuO复合粒子的放热量、温度和燃速进行测试。结果表明:由喷雾干燥法制备的样品为2~4μm微球且混合均匀;纳米CuO的加入使得燃烧热平均降低约300 J/g,燃温平均降低约100℃,最低为1013℃;该气体发生剂的最大燃速为3.94 mm/s,最小为0.76 mm/s,配方残渣率平均降至约6.7%;该配方具有燃烧温度低、固体残渣含量低的特点。5-AT/NaIO_(4)/CuO composite particles are prepared to obtain low-temperature gas-generating agents by spray drying method. The size and morphology of 5-AT/NaIO_(4)/CuO particles are characterized by scanning electron microscope. The combustion performances of gas-generating agents were tested using TG-DSC,automatic oxygen bomb calorimeter,thermocouple and target line method. The results show that 5-AT/NaIO_(4)/CuO composite particles are characterized as 2~4 μm microspheres and well-distributed. The addition of nano CuO reduces average combustion heat by 300 J/g and combustion temperature by 100 ℃.The minimum combustion temperature is 1 013 ℃,and the maximum and minimum burning rates are 3.94 mm/s and 0.76 mm/s respectively. The supplement of nano CuO effectively reduces the burning residuals with the residue rate of about 6.7%. The formula is characterized as low combustion temperature and little residuals.
