▎ 摘　　要

NOVELTY - Device comprises air outlet end (3) of air guide tube (1) is fixed on inner bottom of sealing reaction kettle (2). The air guide pipe includes inner pipe and outer pipe (5), which are sleeved with each other. The space between inner pipe and outer pipe is steam dispersion space, which is used to transport atomized graphene dispersion liquid. The inner pipe is used to transport aluminum alloy powder mixed with hot air. The air outlet end includes first nozzle (6) and second nozzle. The second nozzle is wrapped around outside of the first nozzle. The first nozzle includes fixing plate and multiple first steam spraying pipes. The multiple first steam spraying pipes are arranged obliquely in different directions. The first nozzle is arranged at air outlet end of inner pipe. The inlet end of inner pipe is connected with hot air blower. The second nozzle includes multiple second steam spraying holes. The second steam spraying hole is connected to atomizer through steam conveying pipe. USE - The device is useful for preparing graphene aluminum alloy (claimed). ADVANTAGE - The device: reduces the difficulty of mixing graphene and aluminum alloy powder; improves mixing uniformity; and promotes interface bonding. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene aluminum alloy by preparing the oleuropein solution including adding 0.02-0.05 g graphene oxide to 0.1-0.5 mg/ml 400 ml oleuropein solution to obtain a graphene dispersion. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device for preparing graphene aluminum alloy.
