聚醚环酰胺固体推进剂用键合剂的合成及使用性能

以丙三醇、环氧乙烷、环氧丙烷、氯化亚砜、异氰脲酸等为原料,合成了聚醚环酰胺键合剂。将其应用到推进剂(GAP/HMX/Al/AP)配方中,对成型后的推进剂进行力学性能测试和断面电子显微镜分析。结果表明,此类键合剂可以改善与推进剂中氧化剂的界面粘结性能,有效地提高成型后的推进剂在不同温度下的最大延伸率,但对抗拉伸强度的提高作用不明显。

Synthesis and Performances of Polyether Heretocycle Amide Bonding Agent

In order to solve the dewetting problem of nitramine propellants, polyether heterocycle amide bonding agent was prepared from glycerin, ethylene oxide, propylene oxide,propanetriol and isocyanuric. After incorporated into a glycidyl azide polymer(GAP)/cyclotetramethylene tetranitramine(HMX)/aluminum powder(Al)/ammonium perchlorate(AP) propellant, its mechanical properties were tested and its tensile fracture surface morphologies were investigated by SEM. The results show that the bonding agent can improve the maximum elongation ratio of the propellant at room, low and high temperatures effectively as well as the adhesion between oxidant and binder. But the tensile strength of the propellant need to be improved.
