<Industrial Application Field> The present invention relates to a laminated amorphous alloy ribbon suitable for use as an iron core for power transformers, motors, etc., and a method for manufacturing the same. <Conventional technology> Molten alloys such as Fe-B-Si and Co-Fe-Si are heated at 10 5 to 10 6 °C/
When rapidly solidified at a cooling rate of about seconds, an amorphous alloy ribbon (hereinafter referred to as ribbon) with a thickness of about 20 to 50 μm and having a disordered atomic arrangement is obtained. Such amorphous alloy ribbon has excellent soft magnetic properties, especially Fe
The -B-Si system has a relatively high saturation magnetic flux density and extremely low iron loss, so it is attracting attention as a promising alternative material to the silicon steel sheets currently used as core materials for transformers and motors. Such amorphous alloy ribbon is usually left as a single plate to make wound cores or stacked cores to assemble transformers, but generally speaking, the ribbon thickness is compared to conventionally used silicon steel sheets. Because it is thin and thin, it has the disadvantage of requiring a large number of man-hours for lamination processing. Efforts have been made to eliminate this drawback, such as increasing the thickness of the ribbon, but it has been reported that iron loss deteriorates. If a plurality of ribbons can be bonded together, the number of lamination steps can be reduced, and eddy current loss does not particularly increase, which is advantageous in terms of iron loss. In recent years, attempts have been made to glue ribbons together for this purpose; for example, as proposed in JP-A-56-36336 and JP-A-58-175654, adhesives are evenly applied to the ribbon. After that, pasting
After drying, solidifying and adhering, the core is generally manufactured by shearing and laminating or winding. <Problems to be Solved by the Invention> When a laminated ribbon is created by applying a highly heat-resistant adhesive uniformly to the surface of the ribbon using the conventional method, when forming the ribbon by winding it, the adhesive is removed. Not only is there a disadvantage that non-uniform stress is applied to the ribbon due to the restraint by the layers, deteriorating the magnetic properties, but also
It has been found that depending on the type of highly heat-resistant adhesive or annealing conditions, core loss may deteriorate even when no deformation such as winding is applied. Therefore, it is an object of the present invention to provide a laminated amorphous alloy ribbon and an advantageous method for laminating the ribbons without worrying about non-uniform stress exerted on the ribbon, that is, without deteriorating core loss due to adhesion. <Means for Solving the Problems> As a result of extensive research into an amorphous alloy ribbon laminate that does not cause property deterioration due to adhesion and an advantageous method for producing the same, the inventors discovered that adhesive is interposed in dots. This discovery was made based on the knowledge that an amorphous alloy ribbon laminate with less deterioration of properties could be obtained by a coating method using a coating method. The invention is as follows. In other words, a heat-resistant adhesive whose main component is a heat-resistant polymer compound (excluding borosiloxane resin) is interposed between multiple amorphous alloy ribbons in a dotted manner, and the area where the heat-resistant adhesive is applied is 1. An amorphous alloy ribbon laminate, which is bonded to each other at a coating rate of 1 to 10% and an average interlayer coating amount of 0.5 to 3 g/m 2 . When manufacturing a laminate by bonding multiple amorphous alloy ribbons, a heat-resistant polymer compound (excluding borosiloxane resin) is applied to the surface of one or more amorphous alloy ribbons. Adhesive as the main component is applied in dots, and the applied area ratio of the adhesive is 1 to 10%, and the average amount applied between layers is 0.5.
A method for manufacturing an amorphous alloy ribbon laminate, characterized in that after the concentration of the amorphous alloy ribbon is reduced to 3 g/m 2 , another amorphous alloy ribbon is stacked on top of the other amorphous alloy ribbon, and then pressure is applied to adhere the laminated plate to each other. When laminating and adhering multiple metal foils, the general method is to apply adhesive as evenly as possible to the entire metal surface, stack them, and apply light pressure with a pressure press or pressure roll to bond them. . If non-uniform stress is generated in the ribbon due to adhesion, the cause may be a difference in thermal expansion coefficient between the adhesive layer and the metal ribbon, or non-uniform thickness of the adhesive layer. Therefore, one way to suppress the generation of non-uniform stress in the ribbon, which causes iron loss deterioration, is to eliminate the above-mentioned differences. However, in the case of the combination of an amorphous alloy ribbon and a highly heat-resistant resin, which is the object of the present invention, the thermal expansion coefficient of the polymer compound is much larger, and there is no degree of freedom in making the thermal expansion coefficients the same. In order to solve the above-mentioned problems in the conventional technology, the present invention makes the bonded part dotted and arranges an unbonded part around the bonded point to alleviate the uneven stress generated at the bonded part. It is aimed at Furthermore, in order to fully demonstrate the magnetic properties of the amorphous magnetic alloy ribbon, annealing in a magnetic field at 300 to 350°C is essential, so the adhesive used must be heat resistant. In addition, the present inventor has previously described an amorphous alloy ribbon laminate and its manufacturing method using an adhesive mainly composed of borosiloxane resin that can withstand high-temperature annealing in a magnetic field of 300 to 450°C. Although a patent application has been filed, the present invention does not require as much heat resistance as the borosiloxane resin of the earlier invention, and is annealing under the relatively commonly applied annealing temperature condition of 300 to 350°C. The present invention provides a laminate using an adhesive whose main component is a heat-resistant polymer compound excluding borosiloxane resin, and an effective method for manufacturing the same. Area ratio 1-10%, average coating amount 0.5-3
After applying it in dots so as to give a weight of g/m 2 , it is pre-dried, and another amorphous alloy ribbon is layered on top of the other amorphous alloy ribbon and bonded to each other by pressure bonding. Further, adhesive is applied again in dots on the surface of this ribbon, and the subsequent steps are repeated to produce a laminated amorphous alloy ribbon. Here, it is also possible to perform dot-like application of the adhesive to a plurality of ribbons at the same time and perform pressure bonding only once. Further, examples of suitable application forms of the adhesive in point bonding are as shown in FIGS. 1a to 1d. The invention will be explained based on experimental data. Polyesterimide resin was dispersed and applied in dots on one side of an amorphous alloy ribbon of Fe 78 B 10 Si 12 composition with a plate thickness of 28 μm and a plate width of 5 cm, with an area ratio of approximately 5% and an average coating amount of 0.05. -3g/ m2 . After air-drying, other ribbons were stacked on top of each other, adhesive was applied in approximately the same amount as the first layer, a third ribbon was stacked on top of the other ribbons, and the ribbons were pressed down between pressure rolls and bonded together. Then, the adhesive was bonded by heating at 250°C for 5 minutes. The laminated ribbon produced through the above steps was annealed at 350° C. for 2 hours under a magnetic field of 200 A/m, and then cooled as it was. Figure 2 shows changes in iron loss due to differences in average coating amount. As is clear from the figure, adhesive 0.5-3
It can be seen that the iron loss is improved by coating at g/m 2 . The reason why the average coating amount between layers is limited to 0.5 to 3 g/m 2 is because sufficient adhesive strength cannot be secured with less than 0.5 g/m 2 , and if it exceeds 3 g/m 2 , the amount of coating is limited to 0.5 to 3 g/m 2 . This is because the deterioration of the magnetic properties due to the decrease in the product moment cannot be ignored. Next, typical experimental data regarding the advantages of dotted coating, which is the gist of the present invention, will be shown. Experiments similar to those described above were conducted, and Table 1 shows the results of varying the adhesive application area ratio.

接着の有利な方法が提供される。[Table] Here, the magnetic field annealing conditions were 350°C for 2 hours. As shown in Table 1, the iron loss is improved at a coating area ratio of 1 to 10%, but as the area ratio increases, the iron loss also increases, and when the area ratio is 100%, the iron loss increases. It can be seen that the loss is actually worse compared to the one without bonding. In the present invention, the adhesive application area ratio is limited to 1 to 10% because if it is less than 1%, sufficient adhesive strength cannot be ensured, whereas if it exceeds 10%, uneven stress occurs in the bonded area. This is because the iron loss is insufficiently alleviated and the iron loss deteriorates. Adhesives that can be suitably used in the present invention are those whose main component is one or a mixture of two or more heat-resistant polymer compounds such as polyamideimide, polyesterimide, polyimide, phenoxy, and phenylmethyl silicone resin. . The dot application proposed in the present invention drastically reduces the amount of adhesive used compared to full surface application.
The associated cost reduction cannot be ignored either. <Example> Example 1 An Fe 78 B 10 Si 12 amorphous magnetic alloy ribbon with a width of 5 cm and a plate thickness of 25 μm was coated with an area ratio of 5% and an average coating amount between layers of 0.8.
A polyimide resin adhesive was applied in dots so that the adhesive was g/m 2 , air-dried at 100° C. for 1 minute, and then 5 sheets were pressed together using a roll. Next, continuous heating was performed at 250° C. for 3 minutes to produce a laminated amorphous alloy ribbon.
This laminated ribbon was annealed at 350° C. for 2 hours in a magnetic field of 20 Oe, and then cooled. Iron loss W 13/50 at 1.3T was 0.11W/Kg. There was no peeling of the adhesive layer, and it could be handled as a laminated ribbon even after annealing. Example 2 The same process as in Example 1 was carried out except that the area ratio was 10% and the average coating amount was 1.5 g/m 2 . Iron loss W 13/50 at 1.3T was 0.12W/Kg. Comparative Example 1 Without bonding thin strips by applying adhesive,
It was treated in the same manner as in Example 1. W 13/50 after magnetic field annealing
was 0.14W/Kg. Since there is no lamination, it is thin,
It was inconvenient to handle. Comparative Example 2 The treatment was carried out in the same manner as in Example 1, except that the coating amount between the ribbon layers was 1.4 g/m 2 and the coating was applied uniformly over the entire surface. Iron loss W 13/50 after magnetic field annealing at 350℃ is 0.19W/
It was Kg. Comparative example 3 Formal resin was used as adhesive, other conditions were as in Example 1
processed in the same way. By magnetic field annealing at 350℃,
Adhesive strength was lost and it became impossible to handle it as a laminated ribbon. <Effects of the Invention> According to the present invention, an amorphous alloy ribbon laminate without core loss deterioration due to adhesion can be obtained, and an advantageous method of lamination adhesion is provided.
