Problems solved by technology

However, the composite energetic material prepared by this method has the disadvantages of unstable performance and poor preparation process safety.
At the same time, adding harder components (metal nano-ions) to explosives will also increase the mechanical sensitivity of the target composite and reduce its safety performance

Abstract

The invention discloses a preparation method of an energetic material ignited by a near-infrared laser, which comprises the following steps: dissolving an energetic metal-organic coordination framework material into water at a certain temperature, and then adding CHNO high-energy explosive crystals; standing at room temperature In 1 to 2 days, a new type of energetic material with a layer of energetic metal-organic framework material grown on the surface of the CHNO high-energy explosive crystal is obtained, that is, the target energetic material. The novel energetic material provided by the invention can promote the rapid development of laser ignition technology, and also provide new ideas for the development of novel laser ignition energetic materials.

Description

A kind of near-infrared laser ignition energetic material and preparation method thereof technical field The present invention relates to energetic material technical field, be specifically related to a kind of near-infrared laser ignition energetic material and preparation thereof method. Background technique [0002] The laser ignition mechanism of energetic materials can be divided into two types: photothermal effect mechanism and laser direct dissociation mechanism. in, The mechanism of the photothermal effect is that the molecules of the energetic material instantly generate high-energy heat by absorbing the energy of the laser photon, thereby triggering the energetic Material ignites. The mechanism of direct laser dissociation means that the molecules of energetic materials absorb laser photons of a specific frequency and dissociate, resulting in into highly reactive molecular fragments, thereby triggering a chemical chain reaction and realizing the ignition of...
