摘要
采用光电子能谱(XPS)和显微红外光谱(M IR)研究了4种键合剂(M APO,22#,HX-752,T 313)与CL-20的相互作用。结果表明,键合剂可以作为CL-20的包覆剂;由于海因和三聚异氰酸酯键合剂(22#)的环状结构以及具有较多的极性基团,对CL-20的包覆性最好。含CL-20的NEPE推进剂力学性能测试结果表明,22#键合剂对提高含CL-20的NEPE推进剂体系的力学性能非常有利,其拉伸强度和断裂延伸率均有较大的提高,分别增加了18.8%和103.4%。
The interaction between four bonding agents and CL-20 was investigated by means of XPS and MIR. The analysis proves that bonding agents can act as the liner of CL-20 and a bonding agent containing hydantoin and tripolyisocynate, which is defined as 22^# , is the best liner of CL-20 owing to its cyclic structure and polar groups. The mechanical properties of NEPE propellant containing CI.-20 with 22^# as bonding agent were studied by tensile test. The test results show that the mechanical properties of NEPE propellant are improved and the tensile strength and elongation-to-break are improved by about 18.8% and 103.4% respectively owing to the addition of CL-20. And the tensile strength of propellant increase with the increasing of the content of PET with three functional groups （f=3） as bonding agent.
