摘要 针对丁羟四组元推进剂存在的工艺性能与力学性能的问题,设计合成了新型硼酸酯键合剂。选用二乙醇胺、1-溴代正丁烷、丙烯腈、冰乙酸为原料,合成了N,N-二羟乙基正丁胺、N-(2-腈乙基)二乙醇胺、N,N-二羟乙基乙酰胺中间体。对二乙醇胺和丙烯腈反应的产物做了红外和气-质联用分析,证实合成产物为目标化合物。利用所合成的中间体及甲基二乙醇胺与硼酸三正丁酯,合成了4种新型硼酸酯键合剂,采用丁羟四组元推进剂配方装药,验证了它们的使用效果。结果表明,新合成的4种键合剂都能明显改善药浆流动流平性,其中BA-3和BA-4具有很好的键合效果,显著提升了推进剂的力学性能。 Aiming at the existing problems of processing property and mechanical property of high-energy hydroxyl-terminated polybutadiene propellant,the new borate-ester bonding agents was synthesized.With the diethanolamine,1-bromobutane,acrylonitrile,and glacial acetic acid as raw materials,the intermediates N,N-two hydroxyethyl n-butyl amine,N-(2-cyanoethyl) diethanolamine,and N,N-two hydroxyethyl ethyl amide were synthesized.The reaction product of diethanolamine and acrylonitrile was analyzed by using IR and GC-MS method.It has been testified that the product is target compound.Four kinds of new borate-ester bonding agents were synthesized by utilizing the synthesized intermediates as well as the methyldiethanolamine and tributyl borate.By using the formula of high-energy hydroxyl-terminated polybutadiene propellant,it has been verified that all the newly synthesized bonding agents could improve the flow of the slurry,and among them,BA-3,BA-4 have good bonding effects,which significantly improve the mechanical properties of the propellants.
