Abstract

Abstract: As regarding to inferior bonding of the interface between PBT propellant and HTPB liner，three alkynyl chemicals were introduced to HTPB liner to improve the interface bonding strength and studied via FTIR/ATR，2D IR correlation analysis，gel-content and bonding strength testing. The results indicated that the interface bonding could be improved by using click reaction of azide groups from PBT and alkyne groups from AC-1，AC-2 or AC-3. The peel strength could be increased 80%，40% and 70%，respectively when alkynyl parameter of AC-1，AC-2 and AC-3 were 0.097～0.127，0.051 and 0.097～0.141.

摘要： 针对极性差异较大的叠氮推进剂和丁羟衬层界面粘接体系，采用红外光谱及二维相关光谱分析、凝胶含量、粘接性能测试等方法研究了三种炔基化合物的引入对其界面粘接性能的改善效果。结果表明，在丁羟衬层中引入三种不同分子结构的炔基化合物AC-1，AC-2和AC-3均可提高叠氮推进剂/丁羟衬层的界面粘接强度，当AC-1，AC-2和AC-3的炔基参数[RA]分别为0.097～0.127、0.051和0.097～0.141时，叠氮推进剂/丁羟衬层界面粘接的剥离强度可分别提高约80%，40%和70%。
