NOVELTY - An aluminum alloy curtain wall comprises a square aluminum tube, a polydimethylsiloxane resin layer arranged on an outer side of a mounting wall of the square aluminum tube, a UV resin layer arranged on an outer side of the polydimethylsiloxane resin layer, a rubber layer arranged on an inner side of the mounting wall of the square aluminum tube, hemispheric protrusions arranged on a surface of the rubber layer, and a grating structure arranged on an outer side of a light receiving wall of the square aluminum tube. A surface of the grating structure is provided with a graphene layer. The protrusions with semicircular sections are arranged on the inner side of left and right side walls of the square aluminum tube in the direction of the inner cavity of the aluminum material. The grating structure has a grating cycle of 880 nm, a duty ratio of 0.5 and a thickness of 400 nm. USE - Aluminum alloy curtain wall. ADVANTAGE - The aluminum alloy curtain wall has simple structure, is convenient to prepare and use, and is suitable for industrial production.
