摘要:: 为了改善光敏树脂的燃烧性能，通过添加不同粒径和含量的高氯酸铵（AP）作为氧化剂，利用3D技术打印出含能树脂药柱。考察了AP在光敏树脂中的分散性及燃烧性能。结果表明：粒径为5.28 μm的AP在光敏树脂中的分散性最好；打印成型的含能树脂药柱燃速最快，残渣率最小。与打印成型的纯树脂药柱相比，该药柱的燃速提高了14倍，残渣率降低了94.30%。随着AP的质量分数从10%增至50%，药柱燃烧性能明显改善；当AP的质量分数为50%时，含能树脂药柱的燃速最高，残渣率最小，分别为1.05 mm/s和1.10 %。差热分析表明，含粒径为5.28 μm的AP的含能树脂药柱温度峰值出现最早，放热量最高。

Abstract:: In order to improve the combustion performance of photosensitive resin, energetic resin grain was printed by 3D technology by adding ammonium perchlorate (AP) with different particle sizes and contents as oxidant. Dispersion and combustion performance of AP in photosensitive resin were investigated. The results show that AP with a particle size of 5.28 μm has the best dispersibility in photosensitive resin, burning rate of energetic resin grain formed by printing is the fastest, and its residue rate is the smallest. Compared with the pure resin printed grain, burning rate of the grain increases by 93.34%, and residue rate reduces by 94.28%. With the increase of mass fraction of AP from 10% to 50%, combustion performance of grain is obviously improved. When mass fraction of AP is 50%, burning rate of energetic resin grain is the highest and the residue rate is the lowest, which are 1.05 mm/s and 1.10%, respectively. Differential thermal analysis results show that peak value of energetic resin grain containing AP with a particle size of 5.28 μm appears earliest, and the heat release is the highest.
