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 -NO2 in 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.
