Beschreibung
Zusammenfassung:	The invention discloses an aluminum alloy profile for an antique building, belongs to the technical field of building profile processing, and aims to solve the technical problems that in the prior art, the bonding strength between an aluminum alloy matrix and an antique paint film is insufficient, and the hydrophobic property and the impact resistance of the antique paint film need to be further improved. The aluminum alloy antique paint comprises an aluminum alloy matrix and an antique paint film coated outside the aluminum alloy matrix, and is prepared by the following steps: preparing a polyurethane emulsion containing a siloxane chain segment and a polyethylene glycol chain segment, mixing the polyurethane emulsion with a pretreatment toner with polysiloxane coating and amino modification, a defoaming agent, a dispersing agent, a curing agent and a flatting agent in proportion to form an antique paint vehicle; surface treatment is carried out after multiple times of roller coating, so that a paint film on
