英文摘要: The combustion catalysts with the properties of energetically, insensitivity and circumstance safety will be designed and synthesized by using typical pyridine-based, furazan-based derivatives. Their thermal decomposition property, safety performance and compatibility with other propellant components will be studied by TG, DSC, TG-DSC-MS-FTIR, mechanical sensitivity test and vacuum stability test. The catalytic effects of prepared combustion catalysts in the double base propellant will be evaluated by combustion rating test, and the novel combustion catalysts with a serious of good properties will be explored and researched. Utilizing the thermal decomposition and thermal analysis, combustion flame morphology, combustion wave temperature distribution and flame quenching techniques to reveal the relationship between chemical construction and catalytic effects from the micro perspective and illustrate the catalytic mechanism. Based on one dimensional gas-phase reaction theory, the combustion calculation model of typical propellant containing catalysts will be established. And then we can select new catalysts with good properties of energetically, insensitivity and circumstance safety. The research provides theoretic reference and technology support for the development of novel combustion catalysts in propellant.
