Problems solved by technology

However, in this case, the excessive amount of lubricant causes problems such as clouding of the film (lubricating layer) such as cloudiness, and appearance of air bubbles, particles, unevenness, and collapse on the surface of the film. Defective (poor shape)

Embodiment 1

[0069] To 100 parts by mass of polyamideimide paint HI-406-30 (manufactured by Hitachi Chemical Co., Ltd.), Mitsui "HI-WAX 110P" manufactured by Chemical Corporation, "Plenact KR41B" manufactured by Ajinomoto Seiko (Fine Techno Co., Ltd.) corresponding to 1 part by mass of the polyamideimide resin component as a titanium coupling agent, and "Plenact KR41B" as a polyisocyanate The unstabilized polyamide obtained by reacting trimethylolpropane and diphenylmethyl diisocyanate in a polar solvent with respect to 50 parts by mass of the polyamideimide resin component in a molar ratio of 1:3 An isocyanate compound (Coroneto 2503, manufactured by Nippon Polyurethane Industry Co., Ltd.) was used to obtain a paint.

[0070] Next, this paint was applied and fired on the previously shown base to obtain an insulated wire.

Embodiment 2

[0072] Insulated wires were obtained in the same formulation as in Example 1 except that 10 parts by mass of a titanium coupling agent, 200 parts by mass of an unstabilized polyisocyanate compound, and 10 parts by mass of a lubricant were added.

Abstract

There is provided a insulated electric wire with an electric conductor on which at least a lubricating layer is formed, in which a lubricant is added to the lubricating layer so that granular bodies, with sizes of 5 nm to 3 [mu]m, which are formed by coagulation of the lubricant disperse on a surface of the lubricating layer.

Description

technical field [0001] The present invention relates to an insulated electric wire such as an enameled wire having excellent coil insertability. Background technique [0002] For motors and transformers, for example, coils are formed by winding insulated wires, inserting a plurality of coils into stator slots, and thereafter, welding end portions of the inserted plurality of coils to each other. [0003] Since the insulated wire is wound at high speed when forming a coil, in order to reduce damage to the surface of the insulated wire that may be caused when the coil is formed, it is desired to have an insulated wire with excellent winding linearity, that is, to improve the lubricity of the surface of the insulated wire. [0004] As a method of improving the lubricity of insulated wires, for example, it has been proposed to add a slip agent (lubricant) such as polyethylene oxide to the base resin to obtain a resin coating, apply the resin coating to the insulating layer, and ...
