新型离子型二茂铁基燃烧催化剂的制备及性能
Preparation and Performance of Novel Ionic Ferrocene-Based Combustion Catalysts
摘要
Abstract
In this study,two ferrocene-based catalysts,[FcCH2N(CH3)3+][PbCl3-]·CH3CN(1)and[FcCH2N(CH3)3+]5[BF4-]4[I-](2)(where Fc=Ferrocene),were selected as the research objects to systematically investigate and evaluate their regulatory ef-fects on the combustion performance of solid propellants.TG-DSC tests revealed that both catalysts exhibit excellent thermal sta-bility,with decomposition temperatures of 433.3℃and 481.6℃,respectively.The catalytic effect of the two compounds on the thermal decomposition of ammonium perchlorate(AP)was studied via DSC.When the mass fraction of the added catalyst was 3%,compounds 1 and 2 reduced the thermal decomposition temperature of AP by 48.9℃and 61.1℃,respectively.To fur-ther verify the practical application efficiency of the catalysts,their catalytic performance was evaluated based on a hydroxyl-terminated polybutadiene(HTPB)solid propellant formulation.When compounds 1 and 2 were incorporated into the formulation as combustion catalysts at a mass fraction of 2.5%respectively,the burning rate of the propellant increased from 4.06 mm·s-1 to 8.99 mm·s-1 and 9.06 mm·s-1 under a combustion chamber pressure of 3 MPa.Within the pressure range of 3-10 MPa,the pressure exponent of the propellant decreased from 0.32 to 0.24 and 0.16,respectively.In summary,compound 2 possesses outstanding combustion catalytic performance and holds potential application prospects in high-performance solid propellant systems.关键词
