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 ℃.
