ABSTRACT Nitrogen-rich and poly-nitrogen energetic materials have the advantages of high density, high formation enthalpy, and environmentally friendly as new energetic materials. Among them, cyclo-N5 − is one of the most representative ionic nitrogen compounds. However, at present, the studies are mainly in the field of synthesis. This study mainly explores the compatibility of NaN5 with traditional energetic materials, hydroxy-terminated polybutadiene (HTPB), and ammonium perchlorate (AP). The compatibility is an important parameter to evaluate the safety and reliability of propellants. Therefore, AP, cyclotetramethylenetetranitramine (HMX), cyclotrimethylenetrinitramine (RDX), hexanitrohexazaisowurtzitane (CL-20), HTPB were selected to study the compatibility of NaN5 in the means of differential scanning calorimetry (DSC). The results show that NaN5/AP, NaN5/HMX, NaN5/RDX, NaN5/CL-20 have good compatibility, whereas NaN5/HTPB exhibits moderate compatibility.

NaN5与传统含能材料和HTPB推进剂组分的相容性研究

摘要富氮和多氮含能材料作为新型含能材料具有密度高、生成焓高、环境友好等优点。其中，cyclo-N5 - 是最具代表性的离子氮化合物之一。但目前的研究主要集中在合成领域。本研究主要探讨了 NaN5 与传统含能材料、端羟基聚丁二烯 (HTPB) 和高氯酸铵 (AP) 的相容性。相容性是评价推进剂安全性和可靠性的重要参数。因此，选择AP、环四亚甲基四硝胺(HMX)、环三亚甲基三硝胺(RDX)、六硝基六氮杂异武兹烷(CL-20)、HTPB通过差示扫描量热法(DSC)研究NaN5的相容性。
