Problems solved by technology
[0003] The purpose of the present invention is to solve the above-mentioned aluminum electrolytic capacitor production process in which wood fiber electrolytic paper to be carbonized is added between the anode foil and the cathode foil, and there is a different material insulating barrier between the anode and the cathode, resulting in the contact between the anode and the cathode. The problem of high resistance and interface resistance, and provide a composite insulating paper aluminum electrolytic polymer capacitor production method that can overcome the above shortcomings

Embodiment Construction
[0013] Such as image 3 As shown, the present invention is to add 30-60μm thick synthetic fiber electrolytic paper 7 such as acrylic fiber or nylon fiber between the anode foil 1 and the cathode foil 2, and add 30-60μm wood with the same thickness inside the core. The fiber electrolytic paper 3 is superposed and wound. then press figure 2 The process shown continues to carry out the following process. The carbonization process is completed by heat treatment for 30 to 180 minutes at a temperature of 200 to 300°C. The synthetic fiber electrolytic paper 7 added between the anode foil 1 and the cathode foil 2 is melted and adhered to the electrode foils 1 and 2 to cause the anode foil 1 and the cathode foil 2 to adhere more closely, while the wood fiber on the inside remains after carbonization. Maintain the damaged fibrous tissue. The core after carbonization of the polymer conductive liquid is soaked so that the polymer conductive liquid can be fully absorbed and then cured at a te...

A producing method for compound insulating paper aluminum electrolytic macromolecule capacitor, the method is: the using method and the material of the electrolytic paper using for the core winding of the aluminum electrolytic macromolecule capacitor joins synthetic fiber material electrolytic paper between the anode and the cathode that replaces the firmer way to join a wood fiber between the anode and the cathode and the inner side of the core respectively, but joins the former wood fiber electrolytic paper at the inner side of the core or using with the opposite structure, uses strongpoint of the synthetic fiber and the wood fiber by the compound method using different material electrolytic paper, at the condition, when processing charring to the core in the following working procedure, it is not only the anti-high-pressure identity of the wood fiber can be exerted, but also the compound fiber liquates and adhibits between the anode and the cathode as the center to form the thick and close electric-conduction macromolecule layer, insures the well electric-conduction route of the anode and the cathode, thereby can improve the power of the capacitor and the well resistance identity.
Description
Technical field [0001] The invention relates to a method for producing an aluminum electrolytic polymer capacitor, in particular to a method for producing a composite insulating paper aluminum electrolytic polymer capacitor. Background technique [0002] The structure of the previous aluminum electrolytic polymer capacitor core is as figure 1 As shown, a 30-60 μm thick wood fiber electrolytic paper 3 is added between the anode foil 1 and the cathode foil 2, and the same material of electrolytic paper 3 is also added on the inside, each layer is added, and two layers are added for winding ( winding) to form the core. The purpose of using wood fiber electrolytic paper 3 is to prevent the anode and cathode from being short-circuited when they collide with each other due to mechanical equipment during winding, and to prevent the AL with numerous functional micro-etched pore structures formed between the anode and the cathode. 2 O 3 The acidified film is not damaged or destroyed.
