Embodiment 1

[0032] Configure 30ml 0.1mol / L Fe(NO 3 ) 3 9H 2 O methanol solution, add 1g oxidant ammonium dinitramide (ADN) and stir until the solution is orange-red and transparent; add 0.5g nano-aluminum powder and 10ml 1,2-propylene oxide (PO) to the prepared solution . The color of the liquid gradually deepened, forming a reddish-brown wet gel. After standing and aging for 3 days, supercritical carbon dioxide drying was carried out at 45°C and 9.0MPa to obtain ADN / Al / Fe 2 o 3 Nanocomposite energetic materials.

Embodiment 2

[0034] Configure 30ml 0.2mol / L Al(NO 3 ) 3 9H 2 O to ethanol solution, add 2g oxidant ammonium dinitramide (ADN) and stir until the solution is transparent; add 1.0g nano-aluminum powder and 11ml 1,3-propylene oxide (TMO) to the prepared solution respectively. The color of the liquid gradually deepened, forming a reddish-brown wet gel. After standing and aging for 6 days, supercritical carbon dioxide drying was carried out at 46°C and 9.2MPa to obtain ADN / Al / Al 2 o 3 Nanocomposite energetic materials.

Embodiment 3

[0036] Configure 30ml 0.3mol / L Cu(NO 3 ) 2 ·6H 2 O to the ethylene glycol solution, add 3g oxidant ammonium dinitramide (ADN) and stir until the solution is transparent; add 1.5g nano-aluminum powder and 12ml 3,3-dimethyloxetane to the prepared solution Butane (DMO). The color of the liquid gradually deepened to form a reddish-brown wet gel. After standing and aging for 9 days, supercritical carbon dioxide drying was carried out at 47°C and 9.5MPa to obtain the ADN / Al / CuO nanocomposite energetic material.

Abstract

The invention relates to an ADN / A1 / MxOy-based nano composite energetic material and a preparation method thereof, the method comprises the following steps: dissolving metal (M) salt in a solvent to prepare a solution with a certain mole concentration, weighing an oxidizing agent ammonium dinitramide (ADN) and adding in the above solution, stirring until the solution is in a transparent, respectively adding a fuel nano aluminium powder and a proton trapping agent, stirring for 10-20 minutes, standing and aging for several days, and performing supercritical drying by carbon dioxide, and obtaining the ADN / A1 / MxOy-based nano composite energetic aerogel. The preparation method has the advantages of strong operationality, controllable proportion of oxidizing agent to fuel and simple required equipment, the obtained product has the advantage of good safety performance, is suitable for amplification production, and provides thinking for development of the future energetic material, the ADN / A1 / MxOy-based nano composite energetic material can completely or partially replace the current dangerous and complex energetic material possibly, and is an important direction for development of the nano energetic materials such as solid propellant, and explosives and powders.

Description

technical field [0001] The present invention relates to a kind of composite material—ammonium dinitramide (ADN) / aluminum powder (Al) / metal oxide (M x o y )-based nanocomposite energetic materials. The nanocomposite energetic materials prepared by this method have good prospects in improving the safety characteristics of energetic components, energy release efficiency and mechanical properties, and can be applied to solid propellants, propellants Explosives and pyrotechnics and other fields. Background technique [0002] Nanocomposite energetic materials can realize the nanonization of energetic materials, and solve the problem of agglomeration or adsorption with other substances due to their large specific surface area, high surface energy, and high surface activity during the preparation, storage, and use of ultrafine particles. Phenomenon. In addition, the nanocomposite treatment makes the nanocomposite energetic particles integrate the characteristics of each single co...
