| 摘 要： | 为改善含相稳定硝酸铵(PSAN)推进剂的力学性能,用乙二胺与PSAN颗粒表面反应,制备了乙二胺反应型包覆PSAN。FTIR证实乙二胺与AN之间发生了化学反应。通过吸湿性、接触角测量,对包覆效果进行了表征。结果表明,包覆后PSAN的表面极性明显降低,吸湿性也有一定程度改善。将包覆后的PSAN应用到BAMO-THF推进剂中,发现乙二胺包覆量为0.2%时对推进剂力学性能的改善效果最好,σm提高约46%,εm提高约83%。

| Abstract: | In order to improve the mechanical properties of the propellants containing phase-stabilized ammonium nitrate(PSAN),ethylenediamine was used to react with the surface of PSAN particle to prepare ethylenediamine reactively coated PSAN.The chemical reaction between ethylenediamine and AN was confirmed by FTIR and the coating effect was characterized by hygroscopicity and contact angles test.The results show that the surface polarity of coated PSAN particle decreases obviously and the hygroscopicity decreases ... |
