DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wide and long amorphous metal sheet and a method for manufacturing the same. More specifically, the present invention provides a wide and long sheet that has no wrinkles, has a beautiful appearance, has a shielding effect against electromagnetic waves, and has sufficient mechanical strength for practical use. The present invention relates to an amorphous metal sheet and a method for manufacturing the same.

[Conventional technology]

BACKGROUND ART In recent years, with the development and spread of electronic devices, there has been a need for sheet materials that can protect these devices from the negative effects of static electricity and/or electromagnetic waves and have sufficient mechanical strength for practical use. Conventionally, conductive sheets containing conductive materials containing carbon powder or fibers, or metal foil or powder have been used to protect electronic devices from static electricity. The sheet cannot be said to be sufficiently effective in protecting electronic equipment from electromagnetic waves, nor can it be said that it has sufficient mechanical strength.

Therefore, by using amorphous metal, it has sufficient shielding and protection effects against both static electricity and electromagnetic waves, has excellent waterproof properties, and has sufficient mechanical strength for practical use. The use of laminated sheet materials has been attempted. However, in general, amorphous metals have a width of 2
．． It is supplied as a ribbon-shaped material with a width of 54 to 10.16 cm, and it is expected that a ribbon-shaped material with a width of 20.32 cm will be supplied in the near future. It was considered almost impossible to use it as a material.

[Problem to be solved by the invention]

The present invention aims to make it possible to use an amorphous metal material in the form of a sheet with a desired width. Furthermore, in the present invention, it is possible to efficiently produce a wide and long amorphous metal sheet using a thin film ribbon of amorphous metal as described above with simple operations and with excellent physical properties and performance such as appearance and strength. This is an attempt to provide a possible method.

[Means to solve the problem]

According to the present invention, a plurality of amorphous metal thin film ribbons are arranged in parallel in a lateral direction, the side edges of the ribbons adjacent to each other are conductively bonded, and the length direction of the ribbon is set as the width direction. A wide and long amorphous metal sheet is provided, which is characterized in that it is formed into a long shape.

According to the present invention, a plurality of amorphous metal thin film ribbons are arranged in parallel in a lateral direction, side edges of the ribbons adjacent to each other are electrically bonded, and the longitudinal direction of the ribbon is aligned in the width direction. Provided is a method for manufacturing a wide and long amorphous metal sheet, which comprises forming a wide and long sheet.

The amorphous metal thin film ribbon useful in the present invention may be formed from an amorphous metal sheet alone, or may be formed from an amorphous metal sheet and a conductive metal plating layer covering at least one surface of the amorphous metal sheet. It may be. Examples of conductive metals include copper, nickel,
Cobalt, iron, aluminum, gold, silver, tin, zinc, and alloys of two or more selected from these can be used. The plated thin film obtained by such plating is
The electric field shielding property of the plating layer is added to the magnetic field shielding property of the amorphous metal, and the thin film as a whole
It can exhibit excellent shielding effects against a wide range of electromagnetic waves from low frequencies to high frequencies. The conductive metal plating layer also has the effect of improving the solder or adhesive adhesion of the amorphous metal sheet.

The type of amorphous metal used in the present invention is not particularly limited as long as it has the effect of protecting electronic equipment from static electricity and electromagnetic waves, and can be selected from commercially available materials. In general, it is preferable to select an amorphous alloy which is obtained by adding one or more selected from boron, silicon, carbon, nickel balt, molybdenum, etc. to iron as a main component. For example, Allied's product name M [ETG

In addition to the above-mentioned alloys containing iron as a main component, alloys containing cobalt as a main component (for example, C05o2r+o).

C(hssl 108121 Co55Cr 26CI
Il, CO44M0311C20, C034Cr

201 Cua02r201 NtlSONISOI
T! 5ocuso) etc. can also be used.

These amorphous metal materials are supplied in the form of ribbons or narrow sheets as described above, so in order to use them in the present invention, a plurality of ribbon-like or narrow sheet-like amorphous metal materials must be connected to each other. Opposing side edges of ribbons arranged in parallel and adjacent to each other are adhered with an adhesive or solder to form a sheet-like body having a desired width. At this time, the adhesive is preferably electrically conductive.

In the present invention, the amorphous metal thin film has a 10 to 70
- It is preferable to have a thickness of about 20 to 40 pm.
It is more preferable that the conductive metal plating layer formed on the amorphous metal thin film has a thickness of 0.1
It is preferable to have a thickness of p or more, and 0.1 to 5JI
It is more preferable to have a thickness of about m.

When the thickness of the amorphous metal thin film is greater than 70 mm, its rigidity becomes excessive and it may be difficult to wind it over a long length.

The wide sheet obtained by soldering has electrical conductivity as a whole and has excellent shielding properties. It is preferable to perform solder bonding continuously or in spots. Further, the ribbon may be adhered continuously or in spots with a conductive adhesive. If the ribbons are simply overlapped at their side edges without conductive bonding, or if they are bonded with a non-conductive adhesive, the electrical contact of the electrical thin film will be insufficient and the electric field shielding properties will be insufficient.

Further, the amorphous metal or the metal-plated amorphous metal may have a thin protective film such as a rust preventive agent, a corrosion preventive agent, or the like formed on its surface.

In parallel bonding of amorphous metal thin film ribbons as in the method of the present invention, it is natural and operationally efficient to arrange these ribbons in parallel in the longitudinal direction (i.e., the length direction of the sheet) and adhesively bond them. Because it is also a target,
In this way, 10 to 20 ribbons were lined up in the vertical direction and then glued together to form a wide sheet. However, when long and wide sheets manufactured in this way are used for lamination processing, the joints made by solder or adhesive take on an irregularly hard original state, while the thin metal parts remain flexible. When there is an imbalance in the stress in the original state in the longitudinal direction, and when continuous industrial processing is performed, the unevenness of this original state naturally narrows the width and causes wrinkles, resulting in a wide and long sheet with a uniform and beautiful appearance. It has been found that it is extremely difficult to obtain a laminated sheet of Therefore, as a result of further investigation, the present inventors discovered that instead of arranging and joining the thin film ribbons in parallel in the longitudinal direction, they were arranged in parallel in a direction approximately perpendicular to the length direction of the resulting sheet. The inventors have discovered that by arranging and joining the sheets, it is possible to obtain a wide and long sheet that is free from wrinkles as described above and has a uniform and beautiful appearance.

That is, the present invention is based on the extremely unique and original idea of obtaining a wide and long sheet by horizontally splicing thin film ribbons. This horizontal splicing may be performed by cutting the ribbon to a predetermined length, for example, 1 to 3 m, and then laying it horizontally and splicing it one by one, or by joining multiple ribbons one by one. This may be carried out by cutting vertically spliced sheets having a certain width into a predetermined length (for example, 1 to 3 m), and sequentially horizontally splicing these sheets.

According to the horizontal splicing of such amorphous metal thin film ribbons,
Not only can a sheet of any width be obtained, but even if the sheet is pulled in the direction of travel (longitudinal direction), the tensile force will be dispersed in the lateral direction, so the width will not become narrow or wrinkles will occur. do not have. In addition, when expanding the width of the obtained sheet, when vertically splicing is performed, there are streak-like hard parts and extremely soft parts in the vertical direction, so it is difficult to spread it uniformly when stretched with an expander etc. Although it is difficult,
In the case of horizontal joining, the width can be easily widened without causing such problems.

If desired, the resulting sheet can be laminated by forming a protective coating layer on at least one side. The laminated sheet processing method is not particularly limited and may be based on conventional methods, and examples thereof include the following. That is, the protective coating layer can be formed from a flexible polymeric material, which prevents it from being easily damaged by bending or deformation. Such flexible polymer materials include natural rubber, neoprene rubber, chloroprene rubber, silicone rubber, Hypalon and other synthetic rubbers, PVCl resin, ethylene-vinyl acetate copolymer (εvA) resin, polyacrylic resin, silicone resin, Polyurethane resin, polyethylene (
Synthetic resins such as PE) resin, polypropylene (PP) resin, polyester resin, fluororesin, polyamide resin, Surlyn resin, and in some cases, regenerated cellulose resin (cellophane) or cellulose acetate can be used.

Such a protective coating layer protects the wide sheet of amorphous metal thin film from tearing and tearing due to bending, winding, impact, etc.
Breakage and cracks can be prevented, or even if they occur, their expansion can be prevented, and local drop-off of the amorphous metal thin film can be prevented.

In addition to the above-mentioned effects, the protective coating layer may also have waterproofness, flame retardancy, flame retardancy, and other properties and effects, or may be mixed with necessary additives. It may be.

The thickness of the protective coating layer is not particularly limited as long as it can achieve the desired purpose, but generally it is preferably within the range of 1 to 701M, and preferably within the range of 3 to 30M. , even more preferred.

The protective coating layer may be formed by applying a thin film of the desired flexible polymeric material or by applying a liquid (solution or emulsion, latex, etc.) containing the flexible polymeric material. However, it may be formed by solidifying this coating liquid layer.

The protective coating layer and the amorphous metal thin film wide sheet may be directly bonded together or may be bonded together via an adhesive. There are generally no particular limitations on the types of adhesive materials used as the above adhesives, including incyanate adhesive materials, epoxy adhesive materials, polyacrylic adhesive materials,
Any of polyurethane-based adhesive materials, polyamide-based adhesive materials, rubber-based (especially synthetic rubber-based) adhesive materials, etc. may be used. In addition, acrylates containing amino groups, imino groups, ethyleneimine residues, alkylene diamine residues, acrylates containing aziridinyl groups, amino ester modified vinyl polymer-aromatic epoxy adhesives, amino nitrogen-containing methacrylate polymers, etc. Although this is the preferred adhesive material, other adhesives may also be used.

As mentioned above, solutions, pastes, straights or emulsions of flexible polymeric materials may be coated with known methods such as topping, coating, dipping, laminating, extrusion coating, for forming a protective coating layer.
Methods such as spraying, calendaring, etc. can be applied.

The protective coating layer may also contain a plasticizer, stabilizer, colorant, ultraviolet absorber, flame retardant, flame retardant, and other functional agents.

Furthermore, in the method of the present invention, the amorphous metal wide sheet formed by ribbon bonding is not necessarily flat, but is often wavy, and
There are also uneven steps at the joints. When a protective coating layer is formed on such a wide sheet with unevenness or waves, a large number of air bubbles may be generated between the protective coating layer and the surface of the amorphous metal sheet. The presence of such bubbles may cause local bulging or unevenness in the protective coating layer, reduce the adhesion and adhesive strength between the protective coating layer and the surface of the amorphous metal sheet, and may impair the appearance. In order to prevent the formation of such bubbles, it is preferable to form vent holes in the protective coating layer. The size and formation density of the deaeration holes are not particularly limited and can be set as appropriate, but the size of the deaeration holes is 0.1-1 mm in diameter.
It is preferable to form at a density of 10 to 100 pieces per 100 ci area. In order to form such deaeration holes, the deaeration holes may be formed in advance in the film of the flexible polymer material forming the protective coating layer, or when forming the protective coating layer. , air bubbles may be subjected to suction treatment to form deaeration holes.

In the present invention, one or more of the protective coating layer, adhesive layer, etc. may be made conductive or semiconductive, or insulating, depending on the use and required performance of the sheet obtained. Good too. Alternatively, each layer may be given different conductivity or insulation properties and these may be combined. By doing so, products with various properties or performances can be obtained.

By the way, when the above-mentioned amorphous metal is used in the form of a thin sheet, its tear strength is so low as to be almost zero, and it may easily tear under a low load. Furthermore, such thin sheets of amorphous metal may have relatively low tensile strength and may vary widely in tensile strength.

Therefore, if amorphous metal thin film ribbons are arranged in parallel and formed into a sheet, even if they are bonded by solder or adhesive at their opposing side edges, the longitudinal tensile strength of this sheet will increase. In some cases, the problem is that the quality is insufficient and the variation is large.

In the present invention, in order to solve the above-mentioned problems, a reinforcing layer made of at least one fiber sheet may be included in the above-mentioned protective coating, if desired. At this time, if a fiber sheet with a breaking elongation of 5% or less is used, the difference in elongation between the amorphous metal thin film sheet and the reinforcing layer will be small, and therefore the S-3 load curves of the two will be similar. Amorphous metal thin film sheet layers can exhibit relatively high tensile strength.

The fibers constituting such a fiber sheet include 130
It is preferable to have a tensile strength of kg/mm2 or more and a breaking elongation of 5% or less. There are no particular limitations on the type of fibers having such performance, but the following are exemplified.

Although it is effective in achieving the above effects, it has low elongation and low bending strength. Therefore, when a laminated sheet is required to have high bending resistance, it is preferable to mix the above-mentioned high-strength fibers with other #a fibers having high elongation and high bending strength. Although there is no particular limitation on the type of such high elongation fibers, examples thereof are as follows.

The fiber sheet reinforcing layer used is preferably composed of one or more fiber sheets containing the aforementioned high-strength fibers with a tensile strength of 130 kg/mm" or more and an elongation of 5% or less. In order to improve the bending resistance, It is preferable that high elongation fibers with a tensile strength of 130 kg/mm2 or less and a breaking elongation of 5% or more are mixed.Also, when the fiber sheet reinforcing layer is bonded to both sides of the thin film sheet, these two One of the fiber sheet reinforcement layers is 130k

The fibers in the fiber sheet include short fiber spun yarn, long fiber yarn,
The sheet may be in any form such as split yarn or tape yarn, and the sheet may be a woven fabric, a knitted fabric, a nonwoven fabric, or a composite fabric thereof. Generally, the fibers used in the laminated sheet of the present invention are long fibers (
It is preferably in the form of a filament and preferably forms a plain woven fabric. Further, a woven fabric constructed by stacking parallel warp and weft yarns so as to cross each other and pressing them with leno yarns is particularly preferable.

In addition, if the obtained laminated sheet needs to be flexible, it is preferable that the fiber sheet reinforcing layer be formed of a comparatively coarse knitted fabric, and if it is required to have high strength, It is preferable to use a knitted fabric with high density. Furthermore, in order to cover the high rigidity of the amorphous metal thin film sheet, it may be preferable that the fiber sheet reinforcing layer is formed of a coarse and lightweight knitted fabric.

What is an amorphous metal thin film sheet and a fiber sheet reinforcement layer?
Bonded by any method. Typically, the two are joined together via an adhesive or adhesive polymeric material. There are no particular limitations on the types of adhesive materials used for this purpose, including incyanate adhesive materials, epoxy adhesive materials, polyacrylic adhesive materials, polyurethane adhesive materials, polyamide adhesive materials, rubber adhesive materials (especially synthetic rubber type) adhesive material, etc. may be used. In addition, acrylates containing amino groups, imino groups, ethyleneimine residues, and alkylene diamine residues, acrylates containing aziridinyl groups, amino ester-modified vinyl polymer-aromatic epoxy adhesives, amino nitrogen-containing methacrylate polymers, etc. Although this is the preferred adhesive material, other adhesives may also be used.

In the present invention, if desired, the protective coating layer may be a coating layer made of a flexible waterproof resin.

Such flexible and waterproof resins include natural rubber, neoprene rubber, chloroprene rubber, silicone rubber, Hypalon and other synthetic rubbers, PVC resin, ethylene-vinyl acetate copolymer (EVA) resin, acrylic resin, silicone resin, and urethane resin. Resin, polyethylene (PE
) resin, polypropylene (PP) resin, polyester resin, fluororesin, and other synthetic resins can be used.

The flexible/waterproof resin coating layer is generally formed to have a thickness of 507 or more, and this thickness is preferably 50 to 5000/-1, more preferably 100 to 3000/-1, and even more preferably 200 to 2000/-1. /-.

The flexible/waterproof resin coating layer is flexible/waterproof (it may be formed from a single layer of sealant, but it may be formed from a base layer made of flexible/waterproof resin and formed on this base layer). , and a surface layer made of an antifouling/weather resistant synthetic resin.

In the present invention, fluorine-containing resins and acrylic resins can be used as the antifouling and weather-resistant synthetic resins. That is, the stain-proof and weather-resistant resin surface layer is formed by pasting a film made of a fluorine-containing resin or an acrylic resin on the base layer.

In general, fluorine base resins are flame retardant, stain resistant, and weather resistant, but they are not compatible with ordinary plastic adhesives, so it is extremely difficult to adhere them to the surface of the base layer as is. Therefore, by subjecting the surface of the fluorine-containing resin film to corona discharge or low-temperature plasma treatment to activate it as much as possible, it is possible to bond it with adhesives such as polyvinyl chloride polyepoxy, polyacrylic, and polyester resins. It increases affinity. Usually, the above treatment activates the surface portion of the fluorine-containing resin film. For this purpose, for example 100~
Corona discharge treatment is performed under the conditions of 200 V, 40 to 100 μF, and 1 to 2 A short circuit current.

Such discharge treatment gives the fluorine-containing resin film the desired adhesive ability; however, the surface treatment of the fluorine-containing resin film used in the present invention is not limited to this, and other surface treatments can be used to improve the adhesiveness to the same level or higher. Any material that has the following effects may be used.

As the resin constituting the fluorine-containing resin film, various polyfluoroethylenes synthesized from monomers in which one or more hydrogen atoms of ethylene are replaced with fluorine atoms, such as polytetrafluoroethylene, or some There are various polyfluorochloroethylenes containing chlorine, such as polytrifluorochloroethylene, but also include polyvinyl fluoride, polyvinylidene fluoride, polydichlorodifluoroethylene, and others. Film thickness is generally 0

Furthermore, the fluorine-containing resin film may be mixed with other resins such as MMA, etc., as long as the object of the present invention is achieved.

Commercially available fluorine-containing resin films that can be used in the present invention include Tetra Film (DuPont trademark),
There are Afflex Film (Asahi Glass trademark), KFC Film (Kenbetsu Kagaku), etc.

In the present invention, it is preferable that a film-like fluorine-containing resin with a substantially smooth surface is adhered to the upper surface of the base layer, but there is also a method of applying a fluorine-containing resin solution or emulsion. The fluorine-containing resin film used in the present invention preferably has a tensile strength of 100 kg/cnf or more.

In the present invention, the antifouling/weather resistant resin surface layer may be formed of polyacrylic resin. For this purpose, an acrylic resin film is generally used, but a method of applying an acrylic resin solution or emulsion onto the base layer and drying may also be used.

Acrylic resin films that can be used in the present invention include:
It preferably has a tensile strength of 100 kg/cat or more, 1 to 50 g/my, preferably 3 to 30 g/m
s or a thickness of 3 microns or more (usually 3 to 50 microns), more preferably 4 to 30 microns. The acrylic resin film to be applied may be one manufactured by the T-die method, the inflation method, or any other method. Further, although either a stretched film or an unstretched film may be used, the elongation of the film is preferably about 100 to 300%. Also,
As mentioned above, the thickness is usually about 3 μm to 50 μm, but it may be made somewhat thicker or thinner if sufficient weather resistance and antifouling properties are achieved. The film material is a polyalkyl methacrylate film, for example, a film whose main material is methyl methacrylate, ethyl methacrylate, propyl methacrylate, butyl methacrylate, etc., or acrylate,
A homopolymer or copolymer containing vinyl acetate, vinyl chloride, styrene, acrylonitrile, methacrylonitrile, etc. as a homomonomer or comonomer component is preferably formed into a film. Such films may be adhesively bonded or otherwise applied to the surface of the base layer.

In the present invention, the stain-proof and weather-resistant resin surface layer formed on the flexible and waterproof resin base layer includes, in addition to the above-mentioned fluorine-containing resin and acrylic resin, a polyvinylidene fluoride resin layer and an acrylic resin. It may consist of a laminate of layers, or a laminate of a polyvinylidene fluoride resin layer, an acrylic resin layer, and a polyvinyl chloride resin layer. In these laminates, the thickness of the polyvinylidene fluoride resin layer is 2 to 3
The thickness of the acrylic resin layer is preferably 2 to 4 microns, and the thickness of the polyvinyl chloride resin layer is preferably 40 to 45 microns, but the thickness is not limited to these values.

The adhesion amount of the liquid was adjusted to 100%, and it was dried in a dryer at 90° C. for 1 minute. Next, this coating layer was heat-treated at 180° C. for 1 minute to fix the polyvinyl chloride.

The thickness of the resulting flexible and waterproof resin base layer was 0.3 mm.

5 voices) was applied by heating. The obtained amorphous alloy laminate sheet had good shielding properties against electromagnetic waves, excellent waterproof properties, antifouling properties, and weather resistance, and was also capable of being bonded by heat fusion. Such excellent thermal fusion bondability makes it possible to use amorphous metal membranes in sheet materials (for example, sheets for large tents), which was previously unthinkable, and makes it possible to sew amorphous metal membranes that could not be sewn in the past. , it has become possible to simplify its use and expand its field of use.

The tensile strength of this laminated sheet was measured: 11
8.3 kg/ 3 cmS latitude: 115.8 kg/ 3
cva, and the elongation at break is 3.3% in warp and 3.6% in latitude.
This is sufficient for practical use, and the variation in tensile strength is approximately 3 kg/3 cm for each direction.
The performance could not exceed that of a single sheet of amorphous metal, and there was little variation in strength. Therefore, the minimum tensile strength of the amorphous metal sheet is 65 kg/3 c.
There was no need to worry about m. In addition, the weaknesses in the solder joints were sufficiently compensated for. Moreover, the variation in tensile strength was approximately 3 kg/3 cm, and very stable and desirable sheets were obtained. In addition, the bending resistance of the laminated sheet obtained in the same manner as above without using polyester cloth was

, Bending: When the treatment was performed 1000 times and the strength retention rate after treatment compared to before treatment was measured, it was 85% for those using polyester cloth, while it was 30% for those without polyester cloth. Laminated sheets containing polyester cloth are suitable for applications that involve bending, and laminated sheets that do not contain polyester cloth are suitable for applications that do not require bending.

Further, in this example, the above operation was carried out over a length of approximately 500 m, and a product with a uniform and beautiful appearance was obtained without any wrinkles.

As a comparative example, 13 pieces of the same copper-plated amorphous metal ribbons as above were joined vertically and soldered together, and a wide long sheet with a width of about 1 m was processed in the same way, but quite severe wrinkles occurred every 30 ctn. However, as it was, it was not desirable as a product.

In addition, dangerous manual work was required to prevent the formation of wrinkles, and favorable results could not be obtained.

The entire surface of the ribbon-shaped body (25 mm thick) was plated with copper to a thickness of 1 mm. These copper-plated amorphous alloy ribbons are arranged horizontally (laterally) in parallel to each other,
The side edges of each were soldered together to create a wide long sheet with a width of about 1 m. This wide sheet is continuously fed out horizontally, and the release paper is coated with nylon on both sides of the sheet.
Apply 2-gold to a thickness of 2μ on one side, and make a diameter of about 0.3 m.
A transfer paper with micropores of 500 m in diameter formed at a density of approximately 25 holes per 200 cd of area is stacked in a sandwich shape with one side coated with nylon 12 facing the amorphous metal thin film side, and this laminate is heated with a heating roll. The nylon 12 resin was melt-transferred by heat-pressing from both sides, and the release paper was peeled off to create a wide and long amorphous metal thin film sheet material with a protective coating layer of 2JM thick on both sides.
It was rolled up to the length of . The obtained amorphous metal thin film sheet material had almost no air bubbles, had a smooth and flat surface, had a good appearance with no wrinkles, and had almost no sense of the presence of a protective coating layer. For comparison, 13 similarly plated amorphous metal ribbons were arranged in the vertical direction and bonded with solder to produce a laminated sheet in the same manner as above. This sheet had small wrinkles here and there, and was not preferable compared to the sheet obtained above.

Example 3 The same wide amorphous alloy ribbon as described in Example 2 (but without plating) was joined with a conductive adhesive and the same operation as in Example 2 was performed, resulting in almost the same result as in Example 2. The results were obtained.

〔Effect of the invention〕

According to the present invention, by adopting a horizontal joining method that was difficult to think of in the past, the drawback that wrinkles easily occur in operations for manufacturing long products can be completely eliminated, and wrinkles can be easily generated by simple operations. It is possible to easily obtain a product that is free from wrinkles and wrinkles. Therefore, the present invention
The present invention has great industrial effects as it provides a method for manufacturing products with beautiful appearance without requiring special care. Furthermore, the product obtained according to the present invention has an excellent electromagnetic wave shielding effect, and is therefore useful for forming a simple shield room. In addition, the present invention is applicable to fields where amorphous metals have not been usable due to their high rigidity, low adaptability to other materials, and difficulty in sewing and integration, i.e., for outdoor membrane structures such as tent seat houses. The present invention enables the use of amorphous metals for applications such as flooring materials such as floor sheets for rooms equipped with electronic equipment, indoor interior materials such as wallpaper and blinds, various covering sheets, packaging materials, and packing materials.
