Fe-MOF催化AP热分解行为及对HTPB推进剂燃烧性能的影响
Thermal decomposition behavior of AP catalyzed by Fe-MOF and its effect on the combustion performance of HTPB propellant
摘要
Abstract
In order to effectively control the combustion of hydroxyl-terminated polybutadiene(HTPB)solid propellant,the cata-lyst Fe-MOF was synthesized by coordination self-assembly method.The effect and mechanism of Fe-MOF on the thermal decomposi-tion process of ammonium perchlorate(AP)were studied by catalytic performance combined with in-situ monitoring of gas products,so as to explore the effect of Fe-MOF on the safety performance and combustion performance of HTPB propellant.The results show that the thermal decomposition temperature of AP is reduced to 362.5℃under the action of Fe-MOF.The mechanism is that Fe-MOF can be transformed in situ to produce Fe2O3 nanoparticles with good dispersion during the catalytic process.The intermediate product NH3 of AP decomposition can be oxidized by lattice oxygen oxidation to produce representative products such as N2O,NO and NO2.The combination of ligand consumption of reactive oxygen species accelerates the decomposition of AP.Fe-MOF has excel-lent catalytic effect on the combustion performance of propellant.Under the premise of high safety,the burning rate is increased by 35％.This study provides a reference for exploring the influence of Fe-based catalyst materials on the decomposition process of AP and verifying the safety performance and combustion performance in HTPB.关键词
