一种用于快速点燃高密度烟火药的高能点火药及其制造方法

一种用于快速点燃高密度烟火药的高能点火药。该点火药成分按重量比为奥克托今20～40％、铝粉60～80％、三氧化二铁0～7 .5％，石墨0～1％和氟橡胶0～5％。当其装药密度为2 .0761～2 .2243g/cm3时，爆速大于5635m·s-1，爆压大于10 .4GPa，固体残渣量大于81 .99％，爆温大于3064K，爆热大于4 .34MJ·Kg-1，爆容大于617L·Kg-3。该点火药用于点燃闪光烟火药，试验结果表明，与火药点火相比，该点火药能够提高闪光烟火药在可见光和近红外区的辐射强度。另外，该点火药具有点火快速、高能量、耐投射过载等优点。

High-energyignition charge used for rapidly igniting high-density pyrotechnic composition

A high-energy ignition chargeused for rapidly igniting a high-density pyrotechnic composition includes, by weight,20-40% of octogen, 60-80% of aluminum powder, 0-7.5% of Fe2O3, 0-1% ofgraphite, and 0-5% of fluororubber. When the charge density of the ignitioncharge is 2.0761-2.2243 g/cm<3>, the detonation velocity is 5635 m.s<-1>,the detonation pressure is higher than 10.4 GPa, the solid residue quantity ishigher than 81.99%, the explosion temperature is higher than 3064 K, the explosionheat is larger than 4.34 MJ.kg<-1>, and the explosion specific volume is617 L.kg<-3>. The ignition charge is used for igniting a flashing pyrotechniccomposition. A test result proves that compared with powder ignition, theignition charge can increase the radiation strength of the flashing pyrotechniccomposition in visible light and near-infrared light zones; in addition, theignition charge is quick in ignition, is high in energy and is resistant toprojection overload.
