METHOD FOR MANUFACTURING RESIN FILM FOR THIN FILM-CAPACITOR AND THE FILM THEREFOR |
摘要 |
The present invention provides a method for manufacturing a film for a film capacitor in which a film can be prepared by melt extrusion molding in a thin film having a thickness of 10 μm or less and in which a cost can be cut by simplifying a manufacturing step thereof and a film for a film capacitor. It is a method for manufacturing a film for a film capacitor comprising the steps of charging a melt extrusion molding equipment 10 with a molding material 1 to mold a film 20 for a film capacitor by extruding from a dice 12, interposing the above extruded and molded film 20 for a film capacitor between a pressing roll 31 and a metal roll 32 to cool it and winding up the cooled film 20 for a film capacitor having a thickness of 10 μm or less in order on a winding tube 41 of a winding device 40, wherein the molding material 1 is prepared by adding a fluorocarbon resin to a PEI resin having a glass transition point of 200° C. or higher and a dielectric breakdown voltage of 100 V/μm or more; and a uniaxial elongational viscosity of the above molding material 1 is controlled to a range of 6,000 to 20,000 Pa·s. |
