| 摘 要： | 把混合固化剂、扩链剂聚乙二醇200(PEG200)、交联剂三羟甲基丙烷(TMP)、三官能度环氧乙烷四氢呋喃共聚醚(PET)、端异氰酸酯预聚物以及互穿网络的使用作为调整NEPE推进剂粘合剂网络结构的主要措施。采用单向拉伸手段,研究了它们对NEPE推进剂力学性能的影响。结果表明,TMP能提高推进剂的拉伸强度,异佛尔酮二异氰酸酯(IPDI)与PEG200混合使用能提高推进剂的最大延伸率;三官能度PET能使推进剂的强度和延伸率均有所提高,当粘合剂中三官能度PET的质量分数为50%时,推进剂常温下的拉伸强度和最大延伸率分别比空白样提高了16%和161%;端异氰酸酯预聚物能改善推进剂的力学性能,尤其是对提高最大延伸率有明显作用;将新型聚合物P31引入推进剂粘合剂体系形成互穿网络,推进剂在不同温度下的拉伸强度先增大后减小,延伸率一致增大,当P31的含量占粘合剂体系的5%时,拉伸强度达到最大值。 |

| Abstract: | The mixed curing agents,chain extender polyethylene glycol(PEG200),crosslinking agent tri(hydroxymethyl) propane(TMP),trifunctional copolyether of ethylene oxide and tetrahydrofuran(PET),isocyanate terminated prepolymer and interpenetrating network were used as the major measure to control NEPE propellant binder matrix structure.The effects of the method were studied during unilateral tensile testing.The results indicate that the addition of TMP and IPDI/PEG200 can enhance the tensile strength and the maxim... |
