[0029] The invention provides a method for preparing an aluminum-based composite material, comprising the following steps:
[0030] After mixing aluminum, hydroxide and chloride, ball milling is carried out under a protective atmosphere to obtain an aluminum-based composite material.
[0031] In the present invention, in terms of mass parts, the mass parts of the aluminum, hydroxide and chloride are preferably respectively:
[0032] 60-95 parts of aluminum;
[0033] 5-25 parts of hydroxide;
[0034] Chloride 0-15 parts.
[0035] In the present invention, in terms of parts by mass, the aluminum is preferably 60-95 parts, more preferably 65-85 parts, and most preferably 70-80 parts. In the present invention, the aluminum is preferably metal aluminum powder, the purity of the metal aluminum powder is preferably ≥99%, and the particle size of the metal aluminum powder is preferably 100-200 mesh, more preferably 120-180 mesh. In the present invention, the particle size of the m...
