The processing characteristics, microstructures and mechanical properties of the azide nitramine gun propellant and double-base gun propellant which were both prepared with a method free of volatile solvent were studied by means of a two roller calendar, SEM and tensile strength tester. The results indicate that the rolling and plasticizing temperature, plasticizing times and molding pressure of the azide nitramine gun propellant for the high nitrogen contents( 12.6 ％, 13.0 ％ ) of NC are lower than those of the double-base gun propellant. DIANP( 1,5-Diazido-3-nitrazapentane) can efficiently plasticize the high nitrogen content of NC, the mechanical properties of the gun propellant with DIANP are excellent within a wide range of temperature. The plastication of DIANP on the high nitrogen content of NC is better than that of NG, this can contribute to the gun propellant with a satisified flexibility and an improved low temperature mechanical properties.%采用双滚筒炼胶压延机、扫描电镜、材料试验机等试验对比分析了叠氮硝胺发射药和双基发射药无溶剂法制备的工艺性能、发射药内部形貌、发射药静态力学性能等.结果表明,对于含氮量(质量分数)分别为12.6%、J3.0%的高氮量硝化棉,叠氮硝胺发射药比双基发射药的压延塑化温度、塑化遍数、成型压力均较低.1,5-二叠氮基-3-硝基氮杂戊烷(DIANP)对高氮量硝化棉能充分塑化均匀,高、低、常温力学性能优,说明DIANP对高含氮量硝化棉的溶塑能力优于NG,使发射药具有较好的柔韧性,改善了发射药的低温力学性能.
