Abstract

The invention discloses a co-self-assembled explosive with a dense unit cell accumulation structure and a preparation method thereof. A fresh anhydrous formaldehyde-containing HNIW explosive solutionis prepared, a recrystallization technology is utilized for supersaturation, synergistic co-self-assembly of formaldehyde and HNIW is driven so as to form HNIW / HCHO co-self-assembled explosive crystals with a highly ordered accumulation structure and periodic arrangement. The molecular molar ratio of HNIW to formaldehyde molecules in the prepared co-self-assembled explosive is 2:1, and formaldehyde molecules are embedded in a unit cell cavity, so that the unit cell accumulation structure of the co-self-assembled explosive is very compact, the unit cell accumulation rate is as high as 84.01%, and the co-self-assembled explosive has good thermal stability and low sensitivity. Formaldehyde molecules are embedded to increase the unit cell accumulation dense rate and improve the reaction degree, released gas amount and safety performance of high-energy explosive, thus providing a new thought for high-energy explosive performance control.

Description

technical field

[0001] The invention relates to high-energy explosive crystal construction technology, in particular to a co-self-assembled explosive with a dense unit cell packing structure and a preparation method thereof. Background technique

[0002] Modern weapons put forward higher requirements for energetic materials such as "precise strike, high-efficiency damage, high survivability and environmental adaptability", which makes traditional energetic materials face severe challenges. In early 2017, metallic hydrogen and N 5 - The successful preparation of ions has drawn more attention to the subject of energetic materials. The pursuit of high-energy explosives with high energy, high safety, and excellent comprehensive performance has become a research hotspot in the field of energetic materials. Hexanitrohexaazaisowurtzitane (HNIW) is currently a single-substance explosive that can be prepared in large quantities, has the highest energy and relatively excellent compr...
