中文摘要:
      为了探究聚缩水甘油醚硝酸酯增塑剂(PGNN)在含能推进剂、高聚物粘结炸药(PBX)中应用的可能性,合成了不同数均分子量的PGNN,研究了增塑剂分子量与密度、黏度、玻璃化转变温度及挥发性的关系。采用热重法(TG)研究了PGNN与推进剂、炸药主要组分的相容性,通过感度测试和运输振动试验考察了PGNN的贮运安全性。结果显示,数均分子量为523的PGNN具有较高的密度(1.43 g·cm-3)、较低的玻璃化转变温度(-56 ℃)和较低的挥发性(60 ℃,0.096 mg·cm-2·h-1);PGNN与奥克托今(HMX)、高氯酸铵(AP)、黑索今(RDX)、Al等相容,安全性好,摩擦感度和撞击感度均为0,在4 h的模拟高速公路运输试验中,无燃烧、爆炸等发生。研究表明,数均分子量约500的PGNN是理想的齐聚物增塑剂

英文摘要:
      To explore the application possibilities of polyglycidyl nitrate plasticizer (PGNN) in propellants and PBX explosives, a series of PGNN with different number average molecular weight were synthesized. The relationships between molecular weight and density, viscosity, glass transition temperature and volatility were studied. The compatibility of PGNN with the main components of propellants and explosives were investigated by TG, and the hazard during storage and transportation were studied by sensitivity test and transport vibration test. Results show that PGNN with molecular weight of 523 has a higher density (1.43 g·cm-3), lower glass transition temperature (-56 ℃) and lower volatility (60 ℃, 0.096 mg·cm-2·h-1). PGNN is compatible with HMX, RDX, AP and Al etc., and has good safety characteristics. Both the friction sensitivity and the impact sensitivity are 0, and no combustion or explosion occurs during the 4 hours of simulated highway transportation test. This research reveals that PGNN with molecular weight of about 500 is an ideal oligomer plasticizer.
