摘要:
以聚叠氮缩水甘油醚（GAP）为包覆层材料，甲苯二异氰酸酯（TDI）为交联剂，二月桂酸二丁基锡（DBTDL）为催化剂，乙酸乙酯为溶剂，采用原位聚合法，制备了GAP-TDI/RDX复合材料。利用SEM、FT-IR、XRD、DTA对样品进行了形貌表征和性能测试；利用DTA对其热分解特性进行了研究，结合不同升温速率下的DTA曲线对样品的热分解动力学参数进行了计算。结果表明，GAP成功包覆在RDX表面。所制备的GAP-TDI/RDX复合材料的热分解表观活化能相比原料RDX降低了4.6 kJ/mol，说明复合材料的热分解活性得到提高；GAP-TDI/RDX复合材料的特性落高H50从15.2 cm提升至25.6 cm。
Abstract:
A GAP-TDI/RDX composite was prepared via in-situ polymerization by using Glycidyl azide polymer (GAP) as a coating material, toluene diisocyanate (TDI) as a crosslinking agent, dibutyltin dilaurate (DBTDL) as a catalyst, and ethyl acetate as a solvent. Morphology and performance of the samples were characterized by SEM, FT-IR, XRD and DTA. Thermal decomposition characteristics of the sample were studied by DTA, and thermal decomposition kinetic parameters of the sample were calculated by integrating the DTA curves at different heating rates. The results show that GAP successfully coats on the surface of RDX. The apparent activation energy of thermal decomposition of the prepared GAP-TDI/RDX composites is 4.6 kJ/mol lower than that of the raw material RDX, indicating that the thermal decomposition activity of the composites has been improved. The characteristic drop height, H50, of the GAP-TDI/RDX composite increases from 15.2 cm to 25.6 cm.
