NOVELTY - Method for preparing a metal azide graphene composite involves (i) using water as a reaction medium and adding graphene oxide for ultrasonic treatment for 1 hour, (ii) adding soluble metal salt, nano metal or nano metal oxide, ultrasonically and fully stirring for 2 hours, continuously adding a binder, stirring for 6 hours, dissolving and dispersing uniformly, (iii) placing the uniformly dispersed solution obtained in step (ii) in a shaping mold, placing in liquid nitrogen for freeze-drying, carbonizing the obtained freeze-dried product, controlling the reaction temperature, controlling the protective gas flow rate at 10-30 ml/minute and reacting for 60-120 minutes to obtain a reaction product and (iv) placing sodium azide and stearic acid in a gas generator, controlling the reaction temperature at 100-150 degrees C, introducing azide acid generated by the reaction into a one-way vent tube containing the product after the reaction in step (iii) and controlling the reaction time. USE - The method is useful for preparing a metal azide graphene composite used as an explosive (claimed). ADVANTAGE - The method provides the azide graphene initiating explosive with a particle size that can reach hundreds of nanometers compared with the traditional azide, reduces electrostatic sensitivity, and designs the product into different shapes to match the micro-detonation system charging mode. DETAILED DESCRIPTION - Method for preparing a metal azide graphene composite involves (i) using water as a reaction medium and adding graphene oxide for ultrasonic treatment for 1 hour, (ii) adding soluble metal salt, nano metal or nano metal oxide, ultrasonically and fully stirring for 2 hours, continuously adding a binder, stirring for 6 hours, dissolving and dispersing uniformly, where total amount of soluble metal salt, nano metal or nano metal oxide and graphene oxide is calculated by 100 wt.% and the content of graphene oxide is 5-30 wt.%, (iii) placing the uniformly dispersed solution obtained in step (ii) in a shaping mold of different shapes, placing in liquid nitrogen for freeze-drying, carbonizing the obtained freeze-dried product under an anaerobic condition, controlling the reaction temperature at 300-1000 degrees C, controlling the protective gas flow rate at 10-30 ml/minute and reacting for 60-120 minutes to obtain a reaction product and (iv) placing sodium azide and stearic acid in a gas generator, controlling the reaction temperature at 100-150 degrees C, introducing azide acid generated by the reaction into a one-way vent tube containing the product after the reaction in step (iii) and controlling the reaction time for more than 24 hours. An INDEPENDENT CLAIM is included for the metal azide graphene composite prepared by the method.
