基于点击化学反应的键合剂应用研究

为改善ADN基三唑交联固化体系固体推进剂的粘合剂/固体填料间的界面作用,提高其力学性能,设计合成了基于点击化学反应的键合剂N-炔丙基-2,2'-二羟乙基胺(BA-2)、N-炔丙基-3,3'-二丙腈基胺(BA-7),并采用DSC证明2种键合剂与ADN具有良好的相容性;采用DSC和FT-IR表征了键合剂与以GAP为代表的含能粘合剂的反应性,二者可在60℃进行成环反应;测试并计算了键合剂与ADN的界面特性参数,证明BA-2和BA-7与ADN有较好的吸附作用,有望在ADN基三唑交联固化体系取得应用。

Research on application of bonding agentsbased on "click chemistry"

Two kinds of bonding agent based on"click chemistry" ( BA-2&BA-7) were synthesized and explored for applica-tion in the solid rocket propellants cured by triazole-crosslinked curing system. Compatibility between BAs and ADN was investiga-ted by DSC and it turns out to be compatible with ADN. The reaction capability between BAs and GAP was investigated by means of DSC and FT-IR. The results show that the BAs can react with GAP. Besides, the surface properties have shown that the BAs can be adsorbed on the surface of ADN, thus the synthesized BAs are potentially useful in the triazole-crosslinked curing system.
