Abstract

The invention discloses energy containing ionic salts of 4, 4'-bi [3, 3'-(1-H-5-tetrazolium)] furazan and a preparation method thereof, and belongs to the technical field of energy containing materials. The preparation method is as follows: mixing 4, 4'-bi [3, 3'-(1-H-5-tetrazolium)] furazan barium salt with an equal-molar sulfate of a corresponding cation, filtering precipitates, and evaporating out a filtrate to obtain the target product. The preparation method is simple and easy to industrialize. Nine energy containing ionic salts related in the invention are high in thermostability (Td: 213-289 DEG C), the degree of percussion sensitivity of most compounds is greater than 15J, all the energy containing ionic salts have excellent calculation detonation performance and are potential energy containing materials.

Description

technical field

[0001] The invention relates to 4,4'-bis[3,3'-(1-hydrogen-5-tetrazole)]furazan energetic ion salt and a preparation method thereof, belonging to the technical field of energetic materials. Background technique

[0002] Explosives with improved high temperature properties are often referred to as "heat resistant" or "heat stabilized" explosives. This kind of explosive is an explosive with high thermal stability, appropriate impact sensitivity and high energy, and is widely used in oil well drilling and aerospace. By analyzing some traditional explosives with good thermal stability, it can be found that introducing heterocycles into explosive molecules is an effective way to improve thermal stability. At the same time, the thermal stability of explosives can be further improved and the sensitivity can be reduced by forming energetic salts.

[0003] In recent years, energetic ionic salts have become a hotspot in the field of energetic materials research. Compa...
