CERAMIC INSULATION COATED ELECTRIC WIRE, SELF-FUSING CEREMIC INSULATION COATED ELECTRIC WIRE, COATING COMPOSITION, AND COIL AND VOICE COIL FOR SPEAKER

摘要

A coating composition containing a zirconium compound and a silicon compound is spread over a conductor (1) for baking to form a ceramic insulation coating (2), and a fusion paint obtained by dissolving polyamide resin or polyimide resin with an organic solvent is spread for baking to form a fusion coating (3). Whereby, a self-fusing ceramic insulation coated electric wire capable of retaining coil characteristics at high temperatures can be obtained. In addition, the wire is suitably used for windings such as a voice coil for a high-output speaker.
