Research on Application of Energetic Triazole Ionic Salts in Solid Propellant.

DSC thermal analysis method is employed to evaluate the compatibility of four kinds of energetic triazole ionic salts with some solid propellant main components. The effects of four energetic triazole ionic salts on the combustion properties of glycidyl azide polymer (GAP)propellant are investigated. The results indicate that four kinds of energetic triazole ionic salts have good compatibility with GAP, and nitrocellulose (NC), but they are sensitive with cyclotrimethylene trinitramine (RDX) and nitrocellulose/nitroglycerine (NC+NG) except 3,4,5-triamino-1,2,4-triazolium nitrate (2a). GAP propellant containing containing 1,2,4- triazolium nitrate (1a) has higher burining rate in the range of 12~16 MPa. GAP propellant containing 1,2,3-triazolium nitrate (1b) has higher burning rate in the range of 7~10 MPa. The burning rate pressure exponents for the propellants containing 3,4,5-triamino-1,2,4-triazolium nitrate (2a) and 3,4,5-triamino-1,2,4-triazolium dinitramide (2b) are decreased in the range of 10~16 MPa.
