Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a water vein and an electromagnetic wave shielding sheet, wherein the water vein and the electromagnetic wave shielding sheet are firmly held between the metal thin plate layer and the covering layer for protecting the metal thin plate layer so that even if the metal thin plate layer is thinly formed to a thickness of 0.1 mm or less, The upper and lower coating layers 20 and 30 and the openings 30 and 30 are formed in order to prevent damage to the metal thin plate layer due to the peeling phenomenon and to provide a pleasant feeling even when applied to bedding covered with improved air permeability. 40).

The sowing and electromagnetic wave shielding sheet according to the present invention comprises a thin metal sheet layer 10 and upper and lower cover layers 20 and 30 bonded to both sides of the thin metal sheet layer 10, And a plurality of openings 40 formed in the upper and lower coating layers 20 and 30 so as to form an air passage while being connected to each other at a plurality of locations.

Here, the thin metal plate layer 10 is a thin thin plate (copper plate, aluminum plate, silver plated plate) of 0.1 mm or less. The present invention is applied to a metal thin plate layer 10 having a thickness of 0.01 mm ), And even if a 0.01 mm thin plate is used, the damage of the thin metal sheet 10 due to creasing, tearing and breaking can be prevented by the opening and closing portions 40 and 40 of the upper and lower cover layers 20 and 30 do.

The upper and lower coating layers 20 and 30 are formed by selectively selecting at least one of a nonwoven fabric, a woven fabric, a film, PE, and a foam. For example, 20 are formed of a PET film layer so as to facilitate printing processing and the lower cover layer 30 is formed of a PP nonwoven fabric layer for preventing slippage. As another example, when the sheet is used for insertion into the bedding, The cover layers 20 and 30 may be all formed of a nonwoven fabric or a woven fabric layer. At this time, the upper and lower coating layers 20 and 30 and the thin metal plate layer 10 are bonded together by means of an adhesive, a thermal fusion, and an ultrasonic fusion bonding, So that the local peeling-off phenomenon is prevented.

On the other hand, after the upper and lower coating layers 20 and 30 are bonded to both sides of the metal thin plate layer 10, a finishing band is attached (sewn, adhered, fused) to the edge portion, A seat adjacent to the connecting plate can be easily connected and separated by a detachment means including a velcro, a zipper, a zipper, and a taping when a plurality of sheets are connected to a living room.

The openings 40 may be formed by joining the upper and lower coating layers 20 and 30 in the state of being formed on the metal thin plate layer 10 or by bonding the thin metal plate layer 10 and the upper and lower cover layers 20 and 30 To form an opening portion 40 in a joined state. 2 (a) shows a state in which the upper and lower coating layers 20 and 30 are in contact with each other after a plurality of openings are formed in the metal thin plate layer, and the upper and lower coating layers 20 and 30 are connected to each other 2 (b) shows an open portion 40 in a state where the thin metal plate layer 10 and the upper and lower cover layers 20 and 30 are first bonded to each other. At this time, The upper and lower coating layers 20 and 30 are interlocked with each other by using a punch pin having a sharp tip or using a punching needle N having a saw tooth structure N1 on the outer circumferential surface.

The opening 40 is formed by press-molding in the form of a hole or a long hole so that the embossed portion 42 is formed on one side of the thin metal plate layer 10 and the engraved portion 44 is formed on the other side. 3, the opening 40 is penetrated by a pressing force of a conical pin having a conical tip, so that the engaging portion 44 is formed on the side of the side on which the pressing pin acts, The metal thin plate layer 10 is opened to form the embossed portion 42.

When the upper and lower coating layers 20 and 30 are bonded to both sides of the metal thin plate layer 10, the engraved portions 44 are partially accommodated in the embossed portion 42, and the engraved portions 44 are joined to the inside of the cover layer The bonding strength of the upper and lower coating layers 20 and 30 is firmly maintained and the upper and lower coating layers 20 and 30 are formed by the bonding force in the direction orthogonal to the sheet surface by the embossed portion 42 and the engraved portion 44, The peeling of the coating layers 20 and 30 is prevented.

On the other hand, the coating layer joined to one surface of the thin metal plate layer 10 protrudes in the form of protrusion by the embossing portion 42 to function as a pressurizing protrusion, which is effective for improving blood circulation.

Further, the opening 40 is formed in a hole or a long hole shape. 4 shows a state in which the openings 40 are formed by partially cutting the metal thin plate layer 10 so as to form the openings 40. The openings 40 are formed by the upper and lower coating layers 20 and 30 Which is used as a joining space to be connected to each other, is easily deformed to the metal thin plate layer 10, and flexibility is added to the sheet.

It also provides excellent heat transfer when installed on the floor in winter due to the air circulation and temperature transfer. Especially, when it is used for covering bedding, air circulation and water discharge are smooth, There is an advantage to be provided.

The metal thin plate layer 10 is corrugated or embossed to form a depression 11 and the depression 11 is closed by the upper and lower cover layers 20 and 30, (11a). The depression 11 is formed by corrugating or embossing the metal thin plate layer 10 as shown in FIG. 6, and when the upper and lower cover layers 20 and 30 are bonded to the upper and lower surfaces of the metal thin plate layer 10, Thereby forming the adiabatic buffer cap 11a. Therefore, the heat insulation of the seat is improved by the adiabatic shock absorbing cap portion 11a, and the shock absorbing function can be utilized as a mat for use as a play mat for infants.

Meanwhile, the depressed portion 11 is filled with a functional member including charcoal, celeste, loess, germanium, and wormwood to function as a water shedding function, and has far-infrared radiation, anion effect, and electromagnetic wave shielding function.

The metal thin plate layer 10 is formed to have at least a double structure with the boundary of the intermediate layer 50 and the openings 40 formed in the adjacent metal thin plate layers 10 are shifted to disagree with each other . 5 shows a state in which two metal thin plate layers 10 are bonded to each other with the intermediate layer 50 as a boundary. At this time, the openings 40 of the metal thin plate layer 10 located at the upper part and the metal The positions of the openings 40 of the thin plate layer 10 are shifted from each other.

Therefore, even if the size of the opening 40 is enlarged, the opening portions are complementarily shielded by the plurality of metal thin plate layers 10 stacked in the longitudinal direction. Therefore, in order to improve the flexibility of the metal thin plate layer 10, It is advantageous that the sowing and electromagnetic wave shielding efficiency is maintained to be excellent.

On the other hand, the intermediate layer is formed by selectively selecting at least one of a nonwoven fabric, a fabric, a film, a PE, and a foam in the same manner as the coating layer.
