Claw-type polyene polyamine bonding agent, preparation method thereof and application of claw-type polyene polyamine bonding agent in composite solid propellant

The invention belongs to the technical field of composite solid propellants, and particularly discloses a claw-type polyene polyamine bonding agent, a preparation method thereof and application of the claw-type polyene polyamine bonding agent in the composite solid propellants. Long-chain polyether is arranged in the middle of the bonding agent and can be entangled with a bonding system, and claw-type polyene polyamine derivatives at two ends of the bonding agent contain a plurality of hydroxyl groups, cyano groups and other active groups, so that the bonding agent can better participate in curing of the bonding system and adsorb ammonium nitrate or ammonium perchlorate, and the bonding effect is remarkably improved. 本发明属于复合固体推进剂技术领域，具体公开了一种爪型多烯多胺键合剂、其制备方法和在复合固体推进剂中的应用。该键合剂中间为长链聚醚，可与粘合体系发生纠缠作用，其两端爪型多烯多胺衍生物含有多个羟基、氰基以及其他活性基团，更利于其参与粘合体系固化并吸附硝铵或者高氯酸胺，从而显著提升了键合效果。
