Abstract

The invention discloses an air conditioner aluminum foil material. The air conditioner aluminum foil material comprises the following elements by weight percentage: 0.05%-0.1% of copper, 0.01%-0.05% of zirconium, 0.02%-0.05% of vanadium, 0.01%-0.03% of magnesium, 0.01%-0.1% of silicon, 0.03%-0.1% of manganese, 0.01%-0.05% of rare earth, 0.02%-0.1% of nickel, 0.02%-0.1% of titanium and the balance of aluminum. The air conditioner aluminum foil material gains properly improved strength and enhanced extensibility, so as to meet the strength requirements when used as a radiating fin, and meet the extension requirements for cutting. The invention also discloses a surface treatment method of the air conditioner aluminium foil. The method includes refining, stress removal, cold rolling, foil rolling, washing, alkali cleaning, pickling and film coating, and improves the hydrophobic properties of aluminum foil surface.

Description

technical field [0001] The invention relates to an aluminum alloy material, in particular to an air conditioner aluminum foil material. The invention also relates to a surface treatment method for making the air conditioner aluminum foil. Background technique [0002] At present, the radiator of the refrigerator of the air conditioner is generally made of aluminum alloy material, which is light in weight and low in cost compared with the copper radiator, and is suitable for large-scale use. In the prior art, in order to reduce the manufacturing cost and reduce the weight and volume of the refrigerator, the thickness of the heat dissipation fins of the refrigerator is reduced, so that the mechanical strength of the heat dissipation fins is reduced, and the phenomenon of flipping is prone to occur, which affects the work of the refrigerator Efficiency, when the strength of the cooling fins is improved by changing the material composition, damage will occur during punching. Th...
