The invention belongs to the technical field of aluminum electrolytic capacitors, and particularly relates to a preparation method of an explosion-proof aluminum electrolytic capacitor. The preparation method comprises the following steps of: 1, winding positive electrode foil, inner-layer electrolytic paper, negative electrode foil and outer-layer electrolytic paper which are sequentially laid from inside to outside together to form a wound core package, wherein a positive electrode lead wire is arranged on the positive electrode foil to led out a positive electrode of the capacitor, and a negative electrode lead wire is arranged on the negative electrode foil to lead out a negative electrode of the capacitor; 2, immersing the core package and then placing it in a tubular aluminum shell with a bottom, and covering an opening of the aluminum shell with a rubber plug; 3, chamfering and pre-sealing the opening of the aluminum shell; 4, further curling and sealing the opening of the aluminum ...
