Definitions
- the present invention relates to a self-fusing insulated wire used for manufacturing a deflection yoke coil used for a television receiver, a computer display, and the like.
- the self-fused insulated wire has a fusion layer on the outermost layer, the outermost fusion layer dissolves or swells after coiling in the mold, heating by current, solvent treatment, etc. Since the wires can be fused and solidified, it is possible to easily make a self-supporting coil. In this way, self-fusing insulated wires increase the productivity of electrical equipment coils and reduce manufacturing costs, making them suitable for coil applications such as home electrical equipment, ⁇ A equipment, electrical equipment, and deflection yokes for CRT displays. It is widely used.
- the use of polarizing yoke coils which are frequently used in recent years, such as CRT display devices, is progressing in miniaturization, heat resistance, high voltage, and high frequency.
- the deflection yoke coil has an initial distortion when the coil is formed, that is, when the coil is wound on the winding mold and then heat-fused to form the coil. It can be evaluated by measuring the neck diameter of the coil divided by the amount of torsion), and the dimensional change at room temperature and high temperature is small.
- a self-fusing insulated wire that can meet such demands must have excellent heat deformability and adhesive strength characteristics even at room temperature and high temperature.
- epoxy resin (funoxy resin) has been used as the fusion resin for forming the fusion layer of the self-fusing insulated wire.
- copolymers with a good balance of heat resistance and adhesiveness have been used.
- Polyamide resin is used.
- Such a self-fusing insulated wire is formed by applying and baking an insulating paint, for example, a polyesterimide paint, a polyesterimid urethane paint, or a polyurethane paint, on a conductor a plurality of times.
- an insulating paint for example, a polyesterimide paint, a polyesterimid urethane paint, or a polyurethane paint
- a resin component mainly composed of a polymerized polyamide resin is used as a phenolic organic solvent such as cresol, phenol, xylenol, etc. It is manufactured by applying a fusing paint dissolved in such as by a die, introducing it into a baking furnace and evaporating the solvent to form a fusing layer.
- This production method has the following advantages: for fusion coating, any resin can be used as long as it is soluble in a solvent, and the viscosity required for application to insulated wires can be reduced.
- the phenolic organic solvent inevitably volatilizes into the work environment and contaminates the environment.
- a small amount of a phenolic organic solvent remains.
- the self-fusing insulated wire is coiled around a mold, and then heated and formed into an electric device coil.
- the phenol-based insulated wire is contained in the fusion layer of the self-fusing insulated wire. If a small amount of the organic solvent remains, there is a problem that the organic solvent is volatilized at the time of electric heating during coil winding work.
- the phenolic organic solvent is harmful to the odor and the environment. Therefore, in order to solve these problems, it is necessary to reduce the amount of the phenolic organic solvent remaining in the fusion layer as much as possible.
- Japanese Patent Application Laid-Open No. H10-154440 discloses that, based on 100 weight parts of copolyamide resin, By adding 2 to 10 parts by weight of a high melting point nylon having a melting point of 00 to 300 ° C, the coil is wound around a winding mold and then heat-sealed to form a coil. It describes techniques for reducing initial strain and dimensional change and improving adhesion. However, when a solvent containing an alcohol-based solvent is used for the purpose of reducing odor, the solubility of the high melting point nylon may not be sufficient.

However, odor is generated from the phenolic resin during winding of the DY coil, and the effect of reducing the odor is not sufficient. Also, the dimensional change after winding the DY coil is described, but is not sufficient. However, it does not disclose an alcohol-soluble copolymerized polyamide resin having a specific flexural modulus.
