Abstract
Official abstract text for this publication.
An insulated wire, having at least one layer as an insulation layer, on an outer periphery of a conductor, wherein at least one layer as the insulation layer is composed of a mixed resin of a crystalline resin (A) and a resin (B) having a glass transition temperature higher, by 30° C. or more, than a glass transition temperature of the crystalline resin (A), in which the glass transition temperature is measured by a thermomechanical analysis, and a mixing mass ratio of the mixed resin (a mass of the crystalline resin (A):a mass of the resin (B)) is 90:10 to 51:49; a coil; an electric or electronic equipment; and a method of producing the insulated wire.
First claim
Opening claim text (preview).
The invention claimed is: 1. An insulated wire, comprising at least one layer as an insulation layer, on an outer periphery of a conductor, wherein at least one layer as the insulation layer is composed of a mixed resin of a crystalline resin (A) and a resin (B) having a glass transition temperature higher, by 30° C. or more, than a glass transition temperature of the crystalline resin (A), in which the glass transition temperature is measured by a thermomechanical analysis, and a mixing mass ratio of the mixed resin (a mass of the crystalline resin (A):a mass of the resin (B)) is 90:10 to 51:49, and wherein the crystalline resin (A) includes at least one resin selected from polyetheretherketone, polyetherketoneketone, polyetherketone, polyetherketoneetherketoneketone, and polyphenylene sulfide. 2. The insulated wire claimed in claim 1 , wherein the glass transition temperature of the resin (B) is higher, by 50° C. or more, than the glass transition temperature of the crystalline resin (A). 3. The insulated wire claimed in claim 1 , wherein the resin (B) includes at least one resin selected from polyphenylsulfone, polysulfone, polyethersulfone, and polyetherimide. 4. The insulated wire claimed in claim 1 , wherein the insulation layer composed of the mixed resin is an extrusion covering resin layer. 5. The insulated wire claimed in claim 1 , comprising a thermosetting resin layer including at least one resin selected from polyamideimide, polyetherimide, polyimide, and H-class polyester, on the outer periphery of the conductor. 6. A coil, wherein the insulated wire claimed in claim 1 is subjected to winding working. 7. An electric or electronic equipment, comprising the coil claimed in claim 6 . 8. A method of producing an insulated wire, comprising at least one layer as an insulation layer, on an outer periphery of a conductor, wherein at least one layer as the insulation layer is composed of a mixed resin of a crystalline resin (A) and a resin (B) having a glass transition temperature higher, by 30° C. or more, than a glass transition temperature of the crystalline resin (A), in which the glass transition temperature is measured by a thermomechanical analysis, and a mixing mass ratio of the mixed resin (a mass of the crystalline resin (A):a mass of the resin (B)) is 90:10 to 51:49, and wherein the method comprises: a step of extruding a resin composition, including the mixed resin, on the outer periphery of the conductor, to form the insulation layer. 9. The method of producing the insulated wire claimed in claim 8 , comprising: a step of forming a thermosetting resin layer including at least one resin selected from polyamideimide, polyetherimide, polyimide, and H-class polyester, on the outer periphery of the conductor.
