摘要
Abstract
To improve properties ot the surface deterrents of azidonitramine gun propellant,deterrent precursors 2,4,6-tris(3-butyne-l-yloxy)-1,3,5 triazine(TPYT) and 1,3,5,-triethynylbenzene(TEB) were designed and synthesized using 3-butyn-1-ol and 2-methyl-3-butyn-2 ol as raw materials.The reactivity between the deterrent precursor and azide were researched by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR).The deterred propellants DAG-DG-1 and DAG-DG-2 were prepared by rotating-drum spraying technique,and their combustion performance were measured by the closed-bomb test.The results show that TPYT and TEB can react with glycidyl azide polymer(GAP) at 60℃ and 50℃ respectively.At 60℃,TPYT and TEB can fully react with GAP in 24h and 12h respectively,revealing that their reaction activities are strong,TPYT and TEB can be used for surface deterring of azidonitramine gun propellant and make the progressive burning factor of deterred gun propellants DAG-DG-1 and DAG-DG--2 reach 1.78 and 1.44 respectively and obtain good burning progressivity.关键词
