The present invention relates to a novel method for manufacturing a self-welding wire. More specifically, a thermosetting water-dispersed electrodeposition paint is electrodeposited, the electrodeposited layer is treated with an organic solvent, and after hardening by baking, a resin composition that undergoes a curing reaction by both ultraviolet irradiation and heating is applied. The present invention also relates to a method of manufacturing a self-bonding wire by irradiating ultraviolet rays. When manufacturing coils for electrical equipment, communication device coils, etc., the method of welding and integrating the wires by heat treatment after winding self-fusing wire is the conventional method of varnishing after winding. It has many advantages over the method of heating and curing, such as not requiring impregnated varnish and simplifying the process, and is particularly used for coils for small electrical devices. Conventionally, this type of self-fusing electric wire was produced by manufacturing a regular enamelled electric wire, then coating its surface with vinyl petitral resin, phenoxy resin, nylon, etc.
Currently, it is manufactured by baking. However, this type of self-fusing electric wire has various drawbacks, such as a complicated manufacturing process, a low adhesion between the wires during use, and the use of a large amount of solvent. As a result of extensive research in order to improve the above-mentioned drawbacks, the present inventors formed an electrodeposited layer by an electrodeposition coating method using a water-dispersed electrodeposition paint, and the deposited layer was coated with organic solvent vapor. It has been found that the above-mentioned drawbacks can be overcome by applying an ultraviolet curable resin composition after treatment and baking, and irradiating it with ultraviolet rays. That is, in the present invention, the formed electrodeposited layer is treated with organic solvent vapor, baked, and then coated with an ultraviolet curable resin composition and irradiated with ultraviolet rays, thereby achieving good adhesion between the self-fusing wires. Therefore, a self-fusing electric wire that can be widely used can be manufactured using a simple process of electrodeposition and ultraviolet irradiation, with almost no organic solvent used during manufacturing, and the production efficiency can be significantly improved. As the water-dispersed electrodeposition paint used in the present invention, water-dispersed electrodeposition paints such as acrylic, polyester, polyesterimide, and epoxy acrylic paints are preferably used. The organic solvent for treating the electrodeposited layer used in the present invention is not particularly limited as long as it dissolves or swells the particles of the water-dispersed electrodeposition paint, and preferred examples include dimethylformamide and dimethylacetamide. , N-methylpyrrolidone, etc. The ultraviolet curable resin composition used as the adhesive layer used in the present invention is a composition containing both an ultraviolet curing catalyst and a heat curing catalyst. The resin must be one that hardens both by UV rays and heat, has mechanical strength that can withstand winding after being irradiated with UV rays, and must be fused by heating after winding. ,
Epoxy resins are preferred. It is necessary to select catalysts for both of the above that do not interfere with the respective curing reactions, and examples of catalysts for ultraviolet curing include Lewis acid diazonium salts, BF 4 ,
As the heat curing catalyst, a boron trifluoride amine complex, such as an onium salt of PF 6 or SbF 6 , or a mixture of an aluminum complex and a silanol catalyst, is preferable. A weight ratio of ultraviolet curing catalyst/heat curing catalyst is preferably used in a range of 0.3 to 1.2. After the ultraviolet curable resin composition is applied,
First, it is brought into a B-stage state by irradiation with ultraviolet rays, and self-fusion becomes possible. Then, the uncured portion is cured by heating. The thickness of the fusion layer varies depending on the application, but it is preferably 3 to 10 μm from the viewpoint of adhesive strength after winding. A schematic explanatory diagram of an apparatus for manufacturing a self-fusing electric wire using a water-dispersed electrodeposition paint and an ultraviolet curable resin composition is shown in FIG. 1, and the manufacturing process will be explained based on the diagram. In FIG. 1, 1 is a bare copper wire, which is moved in the direction of the arrow by a winding device. The bare copper wire 1 is electrodeposited in an electrodeposition tank 2 containing water-dispersed electrodeposition paint, then treated with dimethylformamide vapor in a solvent treatment tank 3, baked in baking ovens 4a and 4b, and then transferred to a resin tank 5.
An ultraviolet curable resin composition is applied thereon, passed through a die 6, and then irradiated with ultraviolet rays in an ultraviolet irradiation furnace 7 to obtain a self-fused wire. Note that the drawing speed, electrodeposition conditions, ratio of electrodeposited film to fusion layer thickness, baking conditions, ultraviolet irradiation conditions, etc. will depend on the purpose of use of the wire,
It can be freely changed depending on the required characteristics. Next, the method of the present invention will be explained with reference to Examples and Comparative Examples. Production example 1 Lauryl sulfate ester soda in 100 reaction pot

Bisphenol type epoxy resin) 70Kg, Epicote 10C1 (manufactured by Ciel Chemical Co., Ltd., bisphenol type epoxy resin) 10Kg and DER431 20Kg,
0.5Kg of triphenylsulfonium antimony fluoride as a catalyst for UV curing while stirring at room temperature.
0.5 kg of boron trifluoride monoethylamine complex as a heat curing catalyst and 0.25 kg of anthraquinone as a sensitizer were added and sufficiently dissolved to obtain an ultraviolet curable resin composition (hereinafter referred to as B-2). Examples 1 to 4 Using the apparatus shown in Figure 1, a bare copper wire with a diameter of 0.8 mm was run at a linear speed of 15 m/min using the water-dispersed electrodeposition paint listed in Table 1, and the water-dispersed electrodeposition paint was applied. Approximately 10 V of DC voltage was applied in tank 2 for electrodeposition, dimethylformamide vapor treatment was performed in treatment tank 3 at 150 to 200°C, and passing through baking furnace 4a at 200 to 300°C for 15 seconds.
Subsequently, it was passed through a baking furnace 4b at 300 to 400°C for 15 seconds. Thereafter, the ultraviolet curable resin composition shown in Table 1 was applied using a die in the resin tank 5, and the ultraviolet curable resin composition shown in Table 1 was applied using a mercury lamp with an output of 10 KW in the ultraviolet irradiation furnace 6 for 20 minutes.
The self-fused wires shown in Table 1 were obtained by irradiating ultraviolet rays at a drawing speed of m/min. The resulting self-fused wire was wound tightly around a mandrel with a diameter of 6 mm to a length of 50 mm, and heated at 160°C for 15 minutes and at 180°C for 15 minutes.
Cured by heating at 200°C for 15 minutes.
A sample (closely wound coil) was prepared. A load was applied to one end of the sample prepared under each of the above conditions at room temperature, and the weight of the sample to be disassembled, that is, the adhesive strength at room temperature, was measured, and the results are shown in Table 1. In addition, the temperature at which the adhesive force of 100g is maintained for the sample prepared under the conditions of 160°C x 15 minutes,
Measure heat shock, deteriorated winding, and breakdown voltage,
It is shown in Table 1. Comparative example: Using polyester water-dispersed electrodeposition paint,
An electrodeposited layer was formed on a 0.8 mm bare copper wire, and the wire was passed through a baking furnace under the same conditions as in Example 1. Thereafter, a vinyl formal resin was applied by dip coating according to a conventional method to obtain the self-fused wire shown in Table 1. The obtained self-fused electric wire was tightly wound around a mandrel in the same manner as in Example 1, and heated and cured at 160° C. for 15 minutes to prepare a sample. Using the prepared sample, as in Example 1, the adhesive strength at room temperature, the temperature at which the adhesive strength of 100 g is maintained,
Measure heat shock, deteriorated winding, and breakdown voltage,
It is shown in Table 1. From the results in Table 1, it can be seen that the self-fusing electric wire according to the present invention has superior adhesion at room temperature and at the temperature at which it maintains an adhesive force of 100 g, compared to electric wire obtained by the conventional dip coating method.
