Embodiment 1
[0024] 1) Put metal aluminum with a purity of more than 99.5% in a vacuum furnace, and after melting at 680°C, add white carbon black into the vacuum furnace according to the mass ratio of white carbon black and aluminum as 1:300, and maintain the vacuum at 50rpm Disperse the white carbon black and the molten aluminum for 5 minutes at a high speed, so that the molten aluminum stays in the porous spaces of the white carbon black;
[0025] 2) After cooling the molten aluminum-silica composite obtained in step 1), grind it under the protection of argon, and use the pore size of 100-150nm silica as the isolation film for aluminum powder granulation, which is not only easy to grind, pulverize and disperse , and the obtained aluminum powder has uniform particle size distribution and low oxygen content;
[0026] 3) Add 100 parts by weight of the aluminum powder obtained in step 2) and 0.5 parts by weight of acrylate to the reaction mixer, raise the temperature to 80°C, stir and dispe...
Embodiment 2
[0030] 1) Put metal aluminum with a purity of more than 99.5% in a vacuum furnace, and after melting at 680°C, add white carbon black into the vacuum furnace according to the mass ratio of white carbon black and aluminum as 1:400, and maintain the vacuum at 100rpm Disperse the white carbon black and the molten aluminum for 5 minutes at a high speed, so that the molten aluminum stays in the porous spaces of the white carbon black;
[0031] 2) After cooling the molten aluminum-silica composite obtained in step 1), grind it under the protection of argon, and use the pore size of 100-150nm silica as the isolation film for aluminum powder granulation, which is not only easy to grind, pulverize and disperse , and the obtained aluminum powder has uniform particle size distribution and low oxygen content;
[0032]3) Add 100 parts by weight of the aluminum powder obtained in step 2) and 0.5 parts by weight of methacrylate into the reaction mixer, raise the temperature to 80°C, stir and...
Embodiment 3
[0036] 1) Put metal aluminum with a purity of more than 99.5% in a vacuum furnace. After melting at 680°C, add white carbon black into the vacuum furnace according to the mass ratio of white carbon black and aluminum at 1:500, and maintain the vacuum at 80rpm Disperse the silica and molten aluminum for 3-5 minutes at a high speed, so that the molten aluminum stays in the porous voids of the silica;
[0037] 2) After cooling the molten aluminum-silica composite obtained in step 1), grind it under the protection of argon, and use the pore size of 100-150nm silica as the isolation film for aluminum powder granulation, which is not only easy to grind, pulverize and disperse , and the obtained aluminum powder has uniform particle size distribution and low oxygen content;
[0038] 3) Add 100 parts by weight of the aluminum powder obtained in step 2) and 0.5 parts by weight of styrene into the reaction mixer, raise the temperature to 100°C, stir and disperse at a high speed of 400 rp...
