Abstract
The invention discloses a breakage-proof aluminum alloy. The breakage-proof aluminum alloy comprises a plurality of anodized aluminum alloy sheets and organosilicone sealing adhesive layers which are used for connecting the aluminum alloy sheets, wherein the micropores of anodized films on the surfaces of the anodized aluminum alloy sheets are vacuumized. The invention further discloses a preparation method of the breakage-proof aluminum alloy. The anodized aluminum alloy sheets are adhered together by an organosilicone sealing adhesive through the micropores on the anodized films, the interiors of the micropores are vacuumized due to the water absorbing capacity of the organosilicone sealing adhesive, and thus the aluminum alloy can be improved in overall hardness, and the aluminum alloy has a certain vibration resistance and impact resistance.
