doi:10.12382/bgxb.2021.0198

Abstract

Abstract: 5-AT/NaIO₄/CuO composite particles are prepared to obtain low-temperature gas-generating agents by spray drying method. The size and morphology of 5-AT/NaIO₄/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/NaIO₄/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.

Key words: gas-generatingagent, low-temperature, 5-aminotrazole, sodiumperiodate, spraydrying
