The microcapsule technology is a technology of wrapping a trace amount of substance in a polymer film, and is a micro-packaging technology for storing solid, liquid or gas. Because of its advantages such as masking property, directionality and slow release, it is widely used in the fields of food, tobacco and cosmetics.
The invention prepares an aluminum foil formation reagent into a microcapsule structure, and disperses the microcapsule structure in a solvent to prepare a microcapsule dispersion liquid; and (3) impregnating the aluminum foil cathode region covered with the conductive polymer solid electrolyte layer into the reformulated microcapsule dispersion liquid wrapped with the aluminum foil formation reagent, drying to remove the solvent, and pre-embedding the aluminum foil formation reagent into the capacitor core. Because the microcapsule shell material has the characteristics of insolubility in cold water and solubilization in hot water, the microcapsule shell can not be broken to protect the aluminum foil formation reagent in the procedures of preparing the carbon-containing cathode layer, the silver-containing cathode layer, laminating and bonding and packaging the insulating resin. In the moisture absorption process, the shell of the microcapsule is broken under the action of high-temperature water vapor, the forming reagent is released, the forming reagent and the water vapor form a micro forming solution, and an aluminum foil reforming system is established by combining with electrification aging.
The method can efficiently repair the damaged part of the dielectric layer (the alumina oxide film layer) in the core by using the formed solution under the condition of less moisture absorption amount, increase the insulativity of the dielectric layer, greatly reduce leakage current, improve the aging effect, stabilize the capacity and equivalent series resistance of the product and reduce the reliability risk caused by over-moisture absorption saturation.
