为了设计点火燃烧性能良好且兼容微笔直写工艺的B/KNO3（BPN）点火药配方，分别以聚偏氟乙烯（PVDF）、聚偏氟乙烯‑三氟氯乙烯（F2311）、聚偏氟乙烯‑六氟丙烯（F2602）、聚偏氟乙烯‑六氟丙烯‑四氟乙烯（F2461）、乙基纤维素（EC）、硝化纤维素（NC）、PVDF/NC为黏结剂，设计和制备了7种BPN基点火药油墨，并采用微笔直写装药工艺直写成型，考察了黏结剂种类对样品成型效果、点火燃烧特性和热分解特性的影响。结果表明，黏结剂组分的变化会导致BPN油墨的稠度指数表现一定的差异性，其稠度指数顺序为EC/B/KNO3>PVDF/B/KNO3>PVDF/NC/B/KNO3>NC/B/KNO3>F2311/B/KNO3>F2602/B/KNO3>F2461/B/KNO3，且不同稠度指数的油墨最终呈现不同的成型效果，直写样品截面矩形度的变化趋势与稠度指数一致；氟橡胶为黏结剂的BPN具有较高的燃速和较短的点火延迟，且氟橡胶H含量越高，样品线性燃速越快，不同黏结剂的BPN线性燃速顺序为：PVDF/B/KNO3>F2602/B/KNO3>PVDF/NC/B/KNO3>NC/B/KNO3>F2461/B/KNO3>F2311/B/KNO3>EC/B/KNO3，纤维素黏结剂在减少点火延迟上没有突出贡献；添加氟橡胶可以使BPN起始反应温度降低约145 ℃，NC可以使BPN主反应的起始反应温度降低45 ℃，而EC的添加仅可以使BPN主反应的起始反应温度降低约5 ℃。“,”In order to design the B/KNO3 （BPN） ignition powder formula with good combustion performance and compatibility with the direct ink writing technology， seven BPN‑based ignition powder ink were designed and prepared by direct ink writing technology with different binders including polyvinylidene fluoride （PVDF）， poly （vinylidene fluoride‑trifluorochloroethylene） F2311， poly （vinylidene fluoride‑hexafluoropropylene） F2602， poly （vinylidene fluoride‑hexafluoropropylene‑tetrafluoroethylene） F2461， ethylcellulose （EC）， nitrocellulose （NC） and PVDF/NC. The effects of different binder on the formability， ignition/combustion and thermal decomposition performance were investigated. The results show that the change of binder composition could result in the differentiation of the consistency index of BPN ink. The order of consistency index of different ink is EC/B/KNO3>PVDF/B/KNO3>PVDF/NC/B/KNO3>NC/B/KNO3>F2311/B/KNO3>F2602/B/KNO3>F2461/B/KNO3. The formability of the ink depend on its consistency index. The rectangularity variation tendency of the samples prepared by direct ink writing technology is consistent with the consistency index. The BPN‑based ignition powder containing fluorine rubber presented a higher burning rate and a shorter ignition delay. Meanwhile， the burning rate is faster when the H content is higher in the fluorine rubber. The order of linear burning rate of the BPN‑based ignition powder containing different rubber is： PVDF/B/KNO3>F2602/B/KNO3>PVDF/NC/B/KNO3>NC/B/KNO3>F2461/B/KNO3>F2311/B/KNO3>EC/B/KNO3. However， cellulose binder did not present any significant contribution to reduce the ignition delay. Adding fluorine rubber can reduce the initial reaction temperature of BPN‑based ignition powder by about 145 ℃. NC can reduce the initial reaction temperature of the main reaction of the powder by 45 ℃. The addition of EC can only reduce the initial reaction temperature of the main reaction by about 5 ℃.
