| titleOfInvention | Preparation method of fine particle NTO |
| abstract | The invention belongs to the technical field of energetic materials, and particularly relates to a preparation method of fine particle NTO. The invention provides a preparation method of fine particle NTO, which comprises the following steps: dropwise adding a dissolving solution of the raw material NTO into cold water under the stirring condition, and sequentially filtering and drying the mixed material liquid to obtain fine particle NTO; the solvent of the dissolving solution is nitrogen methyl pyrrolidone; the temperature of the dissolving solution is 60-80 ℃; the temperature of the cold water is 0-5 ℃; the stirring speed is 300-500 r/min. The preparation method provided by the invention has simple process, and the prepared NTO particles are finer and have narrower particle size distribution range. |
