Abstract

The invention discloses a fusion casting explosive, and aims to solve the problems that an existing low-sensitivity fusion casting mixed explosive taking 2, 4-dinitroanisole (DNAN) and TNT as bases isrelatively low in Gurney energy, and a high-Gurney energy fusion casting mixed explosive taking 3, 4-dinitrofurazan-based furazan oxide as a base is relatively high in sensitivity and needs to be insensitive by adding an insensitive agent. The composition of the fusion casting explosive is composed of the following components in percentage by mass: 45% to 56% of 3, 4-dinitrofurazan-based furazanoxide (DNTF) (D50 30 [mu] m to 40 [mu] m), 38% to 43% of 5, 5-bistetrazole-1, 1-dihydroxylammonium dioxide (TKX-50) (D50 80 [mu] m-100 [mu] m), 5% to 10% of aluminum powder (FLQT3) and 1% to 2% of microcrystalline wax (80 #). The open cast explosive is high in detonation velocity and Gurney coefficient and moderate in mechanical sensitivity. The fusion casting explosive is suitable for armor-breaking warheads, explosion-killing warheads and explosion warheads.

Description

technical field [0001] The invention relates to a casting explosive, which is mainly used for a warhead for killing blasts, an armor-piercing warhead and a blasting warhead. Background technique [0002] With the increasingly harsh environment of modern warfare, the requirements for the energy and safety of weapons and ammunition systems continue to increase, and the third-generation high-energy explosives represented by 3,4-dinitrofurazanyloxyfurazan (DNTF for short) have become a research topic. Hot spots, which have a higher energy level (density 1.937g / cm 3 , detonation velocity 9250m / s), can be used to achieve higher metal acceleration capability, but its higher mechanical sensitivity (impact sensitivity 92%) restricts its application in weapon systems. When developing the formulation of DNTF-based melt-cast explosives, due to its high impact sensitivity, it is often necessary to add more insensitive agents, thereby reducing the overall energy output. Therefore, how t...
