| titleOfInvention | Method for preparing super-hydrophobic spherical ammonium dinitramide based on interfacial tension |
| abstract | The invention discloses a method for preparing super-hydrophobic spherical ammonium dinitramide based on interfacial tension, which comprises the following steps: firstly, melting ammonium dinitramide crystals and spraying the ammonium dinitramide crystals onto a low-surface-energy material; and step two, after the surface of the ammonium dinitramide crystal is coated with a layer of low surface energy material, cooling to solidify and crystallize the ammonium dinitramide crystal, thereby obtaining the super-hydrophobic spherical ammonium dinitramide. The invention combines the super-hydrophobic concept and the sphericization two methods for reducing the hygroscopicity of the ADN, the super-hydrophobic spherical ADN crystal is prepared by a solid-phase melting method, the particle size is adjustable, the hygroscopicity is greatly reduced, the adopted main process does not use a liquid solvent or a non-solvent, the method is green and environment-friendly, the process is simple, the cost is low, particularly, under the conditions that the temperature is 60 ℃, the relative humidity is 80 percent and the test time is 400 hours, the moisture absorption rate is reduced by 55 percent compared with the ADN raw material, which is much higher than that of other reported ADN moisture-absorption-preventing methods, and a technical route is provided for the wide application of the ADN in a solid propellant. |
