Embodiment 1
[0042] With 21.8g nano aluminum powder (80nm), 33.5g nano Fe 3 o 4 (50nm), 32.7gBa(NO 3 ) 2 , 4g RDX and 2.5g ferrocene were put into the ball mill and stopped after idling for 15 minutes without adding balls. Add 30 mL of absolute ethanol to the ball mill to make the material wet, then add balls, stop the ball mill after 1 hour, take out the wet material, and dry it in vacuum at 60°C to obtain a mixed Al / Fe 3 o 4 / Ba(NO 3 ) 2 materials.
[0043] Dissolve 2.5 g of NC (11.6% N), 2 g of PVB, and 1 g of DNT in 40 mL of acetone to form a binder solution.
[0044] Mix the above binder solution with Al / Fe 3 o 4 / Ba(NO 3 ) 2 The materials are mixed and kneaded evenly, and granulated with a 12-mesh screen before the materials are dry. The wet granules are evenly dispersed in the tray, and dried at 60°C to obtain the modeling powder.
[0045] Add the molding powder into the fragment mold and cold press at 30 MPa to form it. The formed fragments are kept at 65°C for 5 days ...
Embodiment 2
[0047] 27.4g nano aluminum powder (80nm), 37.4gMnO 2 , 23.2gKClO 4 , 5g PETN and 3g ferrocene were put into the ball mill, idle for 15 minutes without adding balls and then stop. Add 45 mL of absolute ethanol to the ball mill to make the material wet, then add balls, stop the ball mill after 2 hours, take out the wet material, and dry it in vacuum at 55°C to obtain the mixed Al / MnO 2 / KClO 4 materials.
[0048] Dissolve 2 g of NC (12.2% N), 1.5 g of PVB, and 0.5 g of DNT in 30 mL of acetone to form a binder solution.
[0049] Mix the above binder solution with Al / MnO 2 / KClO 4 The materials are mixed and kneaded evenly, and granulated with a 12-mesh screen before the materials are dry. The wet granules are evenly dispersed in the tray, and dried at 60°C to obtain the modeling powder.
[0050] The molding powder was added to the fragment mold and cold-pressed at 40 MPa to form, and the formed fragment was kept at 65°C for 6 days to obtain nano-Al / MnO 2 / KClO 4 Energeti...
Embodiment 3
[0053] 14.2g nanometer aluminum powder (80nm), 52.6gBi 2 o 3 , 21.2gNH 4 ClO 4 , 3g RDX and 2g ferrocene were put into the ball mill, idle for 15 minutes without adding balls, and then stop the machine. Add 40mL of absolute ethanol to the ball mill to make the material wet, then add balls, stop the ball mill after 1.5h, take out the wet material, and dry it in vacuum at 65°C to obtain the mixed Al / Bi 2 o 3 / NH 4 ClO 4 materials.
[0054] Dissolve 3.5 g of NC (12.6% N), 2 g of PVB, and 1.5 g of DNT in 50 mL of tetrahydrofuran to form a binder solution.
[0055] Mix the above binder solution with Al / Bi 2 o 3 / NH 4 ClO 4 The materials are mixed and kneaded evenly, and granulated with a 12-mesh screen before the materials are dry. The wet granules are evenly dispersed in the tray, and dried at 60°C to obtain the modeling powder.
[0056] The molding powder was added to the fragment mold and cold-pressed at 25MPa to form it. The formed fragment was kept at 60°C for 8 d...
