摘要: 为改善含RDX复合固体推进剂的安全性能和力学性能,采用化学包覆方法,对RDX进行了聚3,4-乙烯二氧噻吩(PEDOT)包覆处理,并对包覆前后的RDX进行SEM,FTIR,DTA,TGA,XPS和XRD分析表征。对包覆RDX的表面导电性能进行测试,导电率达5×10-5S/cm,对包覆RDX的机械感度进行了测试,撞击、摩擦感度得到显著降低。进一步对PEDOT/RDX和RDX的PET四组元推进剂进行了装药,得出包覆后推进剂的拉伸性能比未包覆的有显著提高,同时PEDOT包覆RDX后,固体推进剂的能量没有损失。

Abstract: To improve the safe and mechanical properties of composite solid propellant with RDX,chemical modification method was used to modify RDX with Poly (3,4-ethylenedioxythiophenes). The microstructure and morphology of modified RDX and RDX were characterized by SEM,FTIR,DTA,TGA,XPS and XRD measurements. The surface conductivity of modified RDX had greatly increased to 5×10-5 S/cm. The impact sensitivity and friction sensitivity of modified RDX had greatly decreased. In addition,PET propellants with PEDOT/RDX and RDX were manufactured,and the tensile property of PET propellant with PEDOT/RDX was higher than that with RDX,and the energy had no decrease.
