摘要
为了改善力学性能,合成了与硝化甘油(NG)、硝化纤维素(NC)具有良好相溶性的新型热塑性聚氨酯弹性体(TPUE),并应用于改性双基推进剂研究中。研究了热塑性聚氨酯弹性体对硝胺改性双基推进剂的能量性能、力学性能、燃烧性能以及工艺性能的影响。结果表明,在改性双基推进剂中引入TPUE,推进剂的工艺性能、力学性能,尤其是低温力学性能明显提高,燃速和爆热会稍有降低。
In order to improve the mechanical properties, a novel thermoplastic polyurethane elastomer(TPUE) with good miscibility with NG and NC is synthesized and used in modified double base propellant. The effects of TPUE on the mechanical properties, technique properties, combustion and energy properties of nitramine modified double base propellant are studied. It is concluded that when the TPUE is introduced into modified double base propellant, the mechanical properties especially at low temperature,and the technique properties are remarkably improved and the burning rate and explosion heat are slightly lowered.
