摘要/Abstract

摘要： 为了探究NEPE推进剂药浆固化初期高黏度、高模量的流变特性成因,采用流变试验方法、红外光谱分析手段,研究了HMX,AP,NPBA与硝酸酯黏合剂的混合体系流变性能,以及NPBA与HMX的作用力。结果表明,NPBA与HMX的相互作用是NEPE推进剂药浆流变特性的主要成因；NPBA的—OH与HMX的—NO₂易形成氢键；通过调节固化催化剂或提高固化温度等方法,可以缩短或消除NEPE推进剂固化反应初期高模量现象。 

Abstract: With the purpose of exploring the high viscosity and high modulus rheological behavior causes of NEPE propellant slurry in its early curing stage, this thesis adopts methods of rheological test and infrared spectrum analysis to study the hybrid system rheological properties via the interactions between nitrates and HMX, AP, NPBA, respectively, as well as to study the acting force of the interaction between HMX and NPBA. The results show that the interaction between NPBA and HMX is the main cause of rheological behavior of NEPE propellant slurry.—OH in NPBA and —NO_2in HMX can produce H-bond easily, and the high modulus rheological behavior of NEPE propellant slurry in its early curing stage can be shortened or eliminated by adjusting the amount of curing catalyst or raising the curing temperature. 
