| titleOfInvention | Sintered aluminum electrolytic capacitor ultrahigh-voltage anode foil and preparation method thereof |
| abstract | The invention discloses a sintered type aluminum electrolytic capacitor ultrahigh voltage anode foil and a preparation method thereof, wherein the sintered type aluminum electrolytic capacitor ultrahigh voltage anode foil comprises the following steps: 1) mixing spherical aluminum powder with a solvent and an adhesive to prepare aluminum powder slurry; 2) selecting an aluminum foil substrate, and coating the aluminum powder slurry on the surface of an anode foil; vacuum drying treatment is carried out after coating; 3) sintering the coated and dried aluminum foil; 4) and carrying out low-pressure to ultrahigh-pressure anodic oxidation treatment after the sintering process, and obtaining the sintered aluminum electrolytic capacitor anode foil after the last anodic oxidation process. The aluminum foil is prepared by preparing high-purity aluminum powder, a solvent and an adhesive into aluminum powder slurry, then uniformly coating the aluminum powder slurry on the surface of an aluminum foil substrate, and sintering under a certain condition to ensure that the aluminum powder and the aluminum foil substrate are mutually sintered together to form a three-dimensional porous aluminum foil. The method has the advantages of simple process, environmental protection, raw material saving and avoidance of generation of a large amount of acid and alkaline waste liquid containing metal ions generated by the traditional corrosion process. |
