为了研究含六硝基六氮杂异伍兹烷(CL-20)的聚叠氮缩水甘油醚(GAP)基含能热塑性弹性体(GAP-ETPE)发射药的力学性能,制备了几组含CL-20的ETPE基发射药试样,测量了其密度,并通过抗冲击实验、压缩试验对其力学性能进行了研究。结果表明,乙醇-丙酮-四氢呋喃混合溶剂对含氮量不同的硝化纤维素(NC)的溶解能力不同;ETPE分子量增大有利于提高该类发射药的抗冲击性能,但不利于抗压缩性能;混合棉有利于提高该类发射药的抗冲击性能和抗压缩性能。
In order to study the mechanical properties of polyaminated glycidyl ether (GAP)-based thermoplastic elastomer (GAP-ETPE) propellants contained 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaaza-tetracyclo-[5.5.0.05,9.03,11]-dodecane (CL-20),several groups of CL-20 ETPE-based gun-propellent were prepared.Their density were measured and their mechanical properties were studied by impact test and compression test.The results showed that the ethanol-acetone-tetrahydrofuran mixed solvent had different solubility to nitrocellulose (NC) with different nitrogen content.The increase of molecular weight of ETPE was beneficial to improve the impact resistance of such gun-propellant,but it was not conducive to compression resistance.Mixed NC was beneficial to improve the impact resistance and compression resistance of such gun-propellants.
