| titleOfInvention | Double-layer core-shell structure thermite and preparation method thereof |
| abstract | The invention discloses a double-layer core-shell structure thermite and a preparation method thereof, which comprises the steps of firstly adding micron-sized aluminum powder into N, N-dimethylformamide, uniformly mixing, adding an acid solution, stirring at room temperature for reaction for 30-60 min, and obtaining an Al powder dispersion liquid; dissolving PVDF in N, N-dimethylformamide to obtain a PVDF solution; heating the Al powder dispersion liquid to 55-60 ℃, adding a PVDF solution, and reacting for 3-6 h under the temperature condition to obtain a PVDF-coated aluminum primary product; mixing the primary product with sodium dodecyl sulfate and metal M salt, heating to 80-85 ℃, adding a urea solution, and reacting for 3-6 h under the temperature condition to obtain a precursor; and (3) preserving the heat of the precursor for 2-4 h at 280-380 ℃ in an air environment to obtain the double-layer core-shell structure thermite. The double-layer core-shell structure thermit prepared by the method provided by the invention utilizes the synergistic promotion effect between the fluorine-containing polymer PVDF and the metal oxide, so that the thermal reaction performance, the energy release efficiency and the energy release rate of the thermit are obviously improved. |
