Problems solved by technology

[0003] At present, the pyrotechnic coloring agents used are mainly inorganic alkali metal and alkaline earth metal salts, which have the universal properties of inorganic salts and are very easy to absorb moisture. At the same time, perchlorate, chloride salt and nitrate are all water pollutants. They are also very harmful to human health

Abstract

The invention discloses a chemical formula of [Cs(ABTNA)H 2 O] n An insensitive energetic metal-organic framework and a preparation method thereof, comprising the following steps: Step 1: Take a certain amount of deionized water and place it in a round-bottomed flask, place a certain amount of 3-amino-3'-nitroamino-5, 5'-link-1,2,4-triazole is suspended in deionized water and stirred to make it a uniformly dispersed ligand suspension for use; Step 2: Weigh a certain amount of metal cesium salt in a beaker, Add a certain amount of deionized water to configure a certain concentration of cesium metal salt solution, and stir it until it becomes a clear cesium metal salt solution for later use; step 3: heat the ligand suspension prepared in the above step 1 to a certain concentration After temperature, slowly add the cesium metal salt solution prepared in step 2 into the ligand suspension, keep the reaction temperature for a period of time after the addition is completed, then cool naturally, filter and dry the resulting product crystals to obtain pure .

Description

technical field [0001] The invention relates to the technical field of energetic composite materials, and more specifically relates to an insensitive energetic metal-organic framework and a preparation method thereof. Background technique [0002] Pyrotechnics typically consist of an oxidizer and combustibles mixed together in an exothermic chemical reaction. Most importantly, redox reactions must be exothermic, self-sustaining, and under certain conditions independent. Flammable metal powders are often used as flammable substances in pyrotechnics. Oxidants cause the oxidative combustion of combustibles and generate light and heat, and play a role in pyrotechnics by decomposing oxygen at high temperatures. Commonly used are chlorates, perchlorates, and nitrates. In order to increase the strength of the agent, delay the burning speed of pyrotechnics, and enrich the color of the pyrotechnic agent, a small amount of additives, such as epoxy resin and dextrin, are often used. ...
