The present invention relates to a pile rug that includes at least one amorphous metal sheet layer and has excellent shielding properties against electromagnetic waves.

[Conventional technology]

With the development and spread of electronic devices in recent years, these devices are being installed at
There is a need for a floor covering that can protect against the harmful effects of static electricity and/or electromagnetic radiation.

Conventionally, for the above purpose, the upper surface layer of a rug is formed of conductive fibers, or the backing layer of a rug is formed of carbon powder or carbon fibers, or metal foil or a conductive material containing metal powder. It has been put into practice to form it by However, the conductive carpet as described above has insufficient electromagnetic wave shielding properties, and therefore cannot sufficiently protect electronic equipment from the harmful effects of electromagnetic waves.

[Problem that the invention seeks to solve]

The present invention solves the problem of low electromagnetic wave shielding properties of conventional conductive rugs, and provides a new pile rug that has excellent electromagnetic shielding properties and can sufficiently protect electronic equipment from the harmful effects of electromagnetic waves. This is what we are trying to provide.

[Means for solving problems]

The electromagnetic wave shielding pile rug of the present invention comprises a base fabric made of a fiber material, a fiber top layer consisting of a fiber pile layer extending from the base fabric onto the surface thereof, and a fiber top layer formed on the back side of the fiber top layer. a backing layer having at least one metal sheet-containing layer and at least one polymer material layer, the metal sheet-containing layer having a plurality of amorphous metal thin film ribbons arranged in parallel; It is characterized by containing at least one amorphous metal sheet formed by adhering adjacent and opposing side edges to each other.

In the pile rug of the present invention, the pile top surface layer is composed of a base fabric layer made of a fiber material and a pile layer made of piles extending from the base fabric layer onto the surface of the base fabric layer.

There are no particular restrictions on the type of fiber that forms the top layer of the pile, and it can be made from natural fibers such as cotton, linen, and wool, or synthetic polymers such as polyester, polyethylene, polypropylene, nylon 6, nylon 66, and acrylic polymers. It may be formed using one or more types of synthetic fibers such as synthetic fibers, semi-synthetic fibers such as cellulose acetate, and furthermore, glass fibers, carbon fibers, and metal fibers may be used in combination. These fibers may be used in the form of cotton, yarn (spun yarn or multifilament yarn), tape yarn, split yarn, monofilament having a circular or irregular cross section, flat monofilament, or the like. Further, the raised fabric used for the pile top surface layer may be any of the known raised fabrics such as cut pile fabric, loop pile fabric, needle-punch raised fabric, and tufted raised fabric. The pile top surface layer may contain a conductive material such as carbon fiber or metal fiber.

In the rug of the present invention, the polymer material layer in the backing layer, which is laminated and bonded to the back side of the pile top layer, is formed using a thermoplastic polymer material or rubber as a base material. Examples of such polymer materials include polyvinyl chloride (PVC), polyurethane, ethylene-vinyl acetate copolymer, polypropylene, asphalt, and bitumen, and examples of rubber include natural rubber, SBR, and chlorsulfone. Synthetic rubber such as modified polyethylene rubber can be used. The most preferred polymeric material is PVC, which contains plasticizers, fillers,
It may also contain colorants, stabilizers and/or other modifiers. The base material may contain fillers such as atactic polypropylene and/or bitumen, and/or conductive additives such as carbon black, conductive fibers, and metal powder.

In the pile fiber comprising a pile top surface layer and a backing layer of the present invention, the backing layer includes at least one layer containing an amorphous metal sheet.

Previous attempts have been made to utilize amorphous metals to develop materials that have high shielding and protection effects against both static electricity and electromagnetic waves. Generally, amorphous metal is supplied as a ribbon-shaped material with a width of 2.54 to 10.16 cm, and it is expected that a width of 20.32 cm will be supplied in the near future. Therefore, it was considered impossible to utilize such a ribbon-like or narrow-width material in the field of wide-width sheets as in the present invention.

However, the present inventors constructed a wide thin film from a ribbon-like or narrow amorphous metal thin film,
Using this wide amorphous metal sheet, we succeeded in developing a pile rug with excellent electromagnetic shielding properties. To obtain such a wide amorphous metal sheet, a plurality of amorphous metal thin film ribbons are arranged in parallel, and the side edges of adjacent ribbons are adhered. If necessary, this wide sheet may be reinforced with a protective coating layer made of a flexible polymer material on at least one surface thereof to provide a wide and long amorphous metal laminate sheet.

The amorphous metal thin film ribbon useful for the pile rug of the present invention may be formed from an amorphous metal sheet alone, or may be formed from an amorphous metal thin film and a conductive metal plating layer covering at least one surface of the amorphous metal thin film. It may consist of.

Examples of conductive metals used for plating 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 from such a metal has the electric field shielding property of the plating layer added to the magnetic field shielding property of the amorphous metal, and the thin film as a whole is resistant to a wide range of electromagnetic waves from low frequencies to high frequencies. It can show excellent shielding effect. The conductive metal plating layer also has the effect of improving the adhesion of the amorphous metal thin film to solder or adhesive.

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, iron is the main component, along with boron, silicon, carbon, nickel, cobalt,
It is preferable that the material be selected from amorphous alloys obtained by adding one or more selected from , molybdenum, and the like. For example, the product name from Allied
METGLAS No.2605SC (Fe: 81%, B: 13.5%,
(Si: 3.5%, C: 2% amorphous alloy), No.
2605S-2 (amorphous amorphous alloy with Fe: 78%, B: 13%, Si: 9%), No. 2605-CO (Fe: 87 parts, B:
14 parts, Si: 1 part, Co: 18 parts amorphous alloy), No.2826-MB (Fe: 40%, Ni: 38%, Mo:
4%, B:18% amorphous alloy), etc. can be used.

In addition to the above-mentioned alloys whose main component is iron,
Alloy systems containing cobalt as the main component (e.g.
Co ₉₀ Zr ₁₀ , Co ₇₈ Si ₁₀ B ₁₂ , Co ₅₆ Cr ₂₆ C ₁₈ ,
Co ₄₄ Mo ₃₆ C ₂₀ , Co ₃₄ Cr ₂₈ Mo ₂₀ C ₁₈ ), nickel-based alloys (e.g. Ni ₉₀ Zr ₁₀ ,
Ni ₇₈ Si ₁₀ B ₁₂ , Ni ₃₄ Cr ₂₄ Mo ₂₄ C ₁₈ ), and other metal-based alloys (e.g. Pd ₈₀ Si ₂₀ ,
Cu ₈₀ Zr ₂₀ , Nb ₅₀ Ti ₅₀ , Ti ₅₀ Cu ₅₀ ), 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 amorphous metal materials in the form of ribbons or narrow sheets must be mutually used. The opposite side edges of adjacent ribbons are bonded with adhesive or solder to form a sheet-like body having a desired width.
At this time, the adhesive is preferably electrically conductive.

In the pile rug of the present invention, the thickness of the amorphous metal sheet is not particularly limited;
It is preferable to have a thickness of 100 μm or less,
More preferably, it has a thickness of 70 μm or less,
This thickness is more preferably in the range of 10 to 70 μm, even more preferably in the range of 20 to 40 μm.

When the thickness of the amorphous metal thin film exceeds 70 μm, its rigidity becomes excessive and it may be difficult to wind it over a long length. The resulting rug also becomes difficult to handle.

There is no particular limitation on the thickness of the conductive metal plating layer formed on the amorphous metal thin film, but in order to fully exhibit its effect, it is preferably 0.1 μm or more thick, and 0.1 to 5 μm. It is more preferable to have a thickness of about

The wide sheet obtained by soldering amorphous metal thin film ribbon has conductivity as a whole,
It has excellent electromagnetic shielding properties. It is preferable that solder bonding be performed continuously or in spots. The ribbon may also be bonded continuously or in spots with a conductive adhesive. If the ribbons are simply overlapped at their side edges and not bonded with a conductive adhesive, or if they are bonded with a non-conductive adhesive, the electrical contact of the amorphous metal thin film will be insufficient and the electric field shielding properties will be poor. Sometimes that's enough.

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

Further, the amorphous metal thin film ribbon may be warp-spliced by the above-mentioned joining method, but the weft-spliced ribbon is easier to handle during processing, and wrinkles are not formed on the amorphous metal sheet. It has the advantage of being difficult.

The amorphous metal thin film sheet used in the rug of the present invention may be used as is, or may be laminated and composited with a protective coating layer to form an amorphous metal sheet-containing layer as described above.

The protective coating layer is preferably made of a flexible polymeric material and therefore not easily damaged by bending or deformation. Such flexible polymeric materials include natural rubber, neoprene rubber, chloroprene rubber, silicone rubber, Hypalon and other synthetic rubbers, or PVC.
Resin, ethylene-vinyl acetate copolymer (EVA)
Synthetic resins such as resins, polyacrylic resins, silicone resins, polyurethane resins, polyethylene (PE) resins, polypropylene (PP) resins, polyester resins, fluorine-containing resins, polyamide resins, ionomer resins, and in some cases recycled Cellulose resin (cellophane) or cellulose acetate can be used.

The protective coating layer formed from the above-mentioned material prevents the wide sheet of amorphous metal thin film from tearing, breaking, or cracking due to bending, winding, impact, etc., or prevents such occurrence. too,
It is possible to prevent its expansion and to prevent the amorphous metal thin film from falling off locally. In addition to the above-mentioned effects, the protective coating layer may also have waterproofness, flame retardancy, flame retardancy, and other desired properties and effects, or may be mixed with necessary additives. It may be hot.

There is no particular limitation on the thickness of the protective coating layer as long as it achieves the desired purpose, but it is generally between 1 and 2.
Preferably within the range of 70 μm, 3 to 30 μm
It is even more preferable to fall within this range.

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.

As mentioned above, when solutions, pastes, straights or emulsions of flexible polymeric materials are used for forming the protective coating layer, known methods such as topping, coating, dipping,
Methods such as lamination, extrusion coating, spraying, calendering, 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.

When the flexible polymer material thin film for the protective coating layer is attached to the amorphous metal thin film sheet, the two may be directly bonded or may be bonded via an adhesive. There are generally no particular limitations on the types of adhesive materials used as the above adhesives, including isocyanate adhesive materials, epoxy adhesive materials, polyacrylic adhesive materials, polyurethane adhesive materials, polyamide adhesive materials, rubber adhesive materials (especially Any synthetic rubber-based adhesive material may be used. In addition, amino groups, imino groups, ethyleneimine residues,
Acrylates containing alkylene diamine residues, acrylates containing aziridinyl groups, amino ester-modified vinyl polymer-aromatic epoxy adhesives, amino nitrogen-containing methacrylate polymers, etc. are also preferred adhesive materials, but other adhesives may also be used in combination. You may.

In addition, in the pile rug of the present invention, the amorphous metal wide sheet formed by ribbon bonding is not necessarily flat, and in many cases,
It is undulating in a wavy manner, and there are uneven steps at the joints. When a protective coating layer is formed on such a wide sheet with unevenness and waves, between the protective coating layer and the surface of the amorphous metal sheet,
Many air bubbles may become trapped. 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 such trapping of air bubbles, it is preferable to form vent holes in the protective coating layer. There are no particular limitations on the size or formation density of the degassing holes, and they can be set as appropriate; however, the size of the degassing holes is 0.1 to
It is preferable that the particles be formed at a density of 10 to 100 pieces per 100 cm ² of 1 mm. In order to form such degassing holes, degassing 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. Alternatively, air bubbles may be suctioned from the film side to form degassing holes. Further, degassing holes may be formed in the amorphous metal thin film.

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

When the amorphous metal sheet used in the pile rug of the present invention is made of metal foil having a thickness of 50 μm or less, its mechanical strength is extremely low. Especially when using amorphous metal thin film,
Its mechanical strength is extremely low, its tear strength is almost zero, and it easily tears under low loads. Furthermore, such amorphous metal thin films have relatively low tensile strength and have large variations in strength. Therefore, if amorphous metal thin film ribbons are arranged in parallel to form a sheet, even if they are bonded by solder or adhesive at their opposing side edges, the longitudinal tension of this sheet will be Problems may arise in that the strength is insufficient and also has large variations.

In order to solve the above-mentioned problems, in the backing layer having at least one amorphous metal sheet-containing layer disposed in the pile rug of the present invention, this backing layer is formed of a fiber fabric. The at least one fiber-reinforced layer is disposed adjacent to the amorphous metal sheet-containing layer. The fiber reinforcement layer is also effective in improving the dimensional stability, preventing warping, and improving the placement stability of pile carpets in general, and tile carpets in particular.

Since the amorphous amorphous metal thin film has an extremely low elongation at break, the fiber fabric for the fiber reinforcing layer in the present invention is a fiber having an elongation at break of 5% or less and preferably a tensile strength of 130 Kg/mm ² or more. It is preferable to use one consisting of: When such a low elongation fiber reinforced layer is placed close to the amorphous metal sheet layer, the shapes of the S-S load curves of both are similar, so the fiber reinforced layer provides greater reinforcement than the amorphous metal sheet layer. The effect can be shown. Particularly in the case of rugs, they are constantly subjected to tread pressure, and as a result, loads are applied to the rug in the direction of expansion. Since the elongation of the amorphous metal thin film is low, there is a risk of it being torn due to this elongation force. At this time, if a fiber reinforcing layer containing low elongation fibers is used, the elongation of the entire rug can be suppressed and tearing of the amorphous metal thin film can be prevented. The types of fibers having such performance are not particularly limited, but are exemplified by the following.

■■■ Turtle shell [0014] ■■■ As mentioned above, there are no particular limitations on the types of fibers and fabrics that form the fiber reinforcing layer, and the fabrics include woven fabrics,
It may be either a knitted fabric or a nonwoven fabric, but a coarse woven fabric or knitted fabric, or a nonwoven fabric is most preferable.
The type of fibers forming these fabrics is not particularly limited and may be any of glass fibers, polyester fibers, polyamide fibers, polypropylene fibers, rayon fibers, etc., but glass fibers and polyester fibers are preferred.

There are no particular restrictions on the placement position of the fiber reinforcing layer as long as at least one of the layers is placed close to the amorphous metal sheet layer. position), the lower layer portion (back surface portion), or the intermediate layer portion. Additionally, the fiber reinforcement layer may be the only layer disposed in close proximity to the amorphous metal sheet layer.

There are no particular limitations on the basis weight (weight) or thickness of the fabric forming the fiber reinforcing layer, but for example, when it is placed in the middle layer of the backing layer, it is 10 to 200 g/m ²
It is preferable to have a basis weight of 50 to 150 g/m ²
It is more preferable to have a basis weight of . In addition, when the fiber reinforcing layer is arranged on the lower layer (back side) of the backing layer, its basis weight is preferably 10 to 100 g/ ^m2 , more preferably 20 to 70 g/ ^m2 . .

When the fiber reinforcement layer is disposed within the backing layer, the fabric forming it impregnates a portion of the polymeric material forming the backing layer to provide suitable hardness and stiffness.

Also, when the fiber reinforcement layer is arranged to form the back side of the backing layer, it may be impregnated with a portion of the polymer material to give suitable hardness and rigidity. If it oozes out onto the back side of the rug, it will have a non-slip effect on the rug.

In the pile rug of the present invention, at least one layer of amorphous metal sheet must be included in at least the backing layer. Preferably, the backing layer is composed of two layers, upper and lower, made of a polymer material, and an amorphous metal sheet layer disposed between them. In addition to the amorphous metal sheet layer disposed in the backing layer, other metal sheet layers may be incorporated into other layers, such as the pile top layer.

The pile rug of the present invention may be in the form of an elongated carpet. However, such long carpets are troublesome to transport, carry in, and install the flooring, and when local stains occur, it is impossible to locally replace them, and local repairs can significantly impair the aesthetics. There is a problem with this.

In recent years, carpet tiles of various shapes, such as squares, rectangles, and rhombuses, have come into use as bedding materials to solve the above-mentioned problems. Such carpet tiles have the advantages of being easy to transport, carry in, and install, allowing for local replacement, and being able to form desired patterns by combining carpet tiles of various colors. are doing.

The pile rug of the present invention may be in the form of a tile carpet having the above advantages.

The amorphous metal sheet layer included in the pile rug of the present invention may be a single layer or may be a plurality of layers. Further, the amorphous metal sheet may be a non-porous sheet or may have one or more holes.
