Abstract：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 1 441 K, 1 611 K and 1 309 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.
