Abstract

PURPOSE: To prepare an insulated wire having low friction coefficient and high abrasion resistance without lowering the heat resistance of the base resin, by coating a wire with an insulation paint containing a specific amount of boron nitride powder having specific particle diameters, and baking the coated wire.
CONSTITUTION: The objective insulated wire can be prepared by coating a conductor with an insulation paint obtained by adding 0.5W10wt% of boron nitride powder having an average particle diameter of ≤10μ to the resin component (e.g. polyesterimide) of the paint, and baking the coated wire. The coating may be carried out by applying the paint directly to the conductor or pref. by applying the paint to the conductor coated with other insulation film. The thickness ratio of the top layer to the interlayer is pref. 1W5 to 10. For the homogenous dispersion of boron nitride powder, the dispersing operation is pref. carried out either by dispersing the boron nitride in the insulation paint in high concentration (≥50wt%) and then diluting the concentrate with the insulation paint free of the additive, or by dispersing boron nitride powder in a solvent such as Xylene, and then adding the insulation paint to the dispersion.
USE: Coils of electrical or communication equipment.
