Among these, electromagnetic pulse refers to a wavelength generated by the interaction between electricity and magnetism, and occurs naturally in all kinds of electromagnetic products such as electrical appliances used in homes, information and communication devices, or natural phenomena such as lightning strikes. It is also caused by a nuclear explosion.

These electromagnetic pulses are powerful enough to physically destroy electronic devices, and electronic devices exposed to electromagnetic pulses can be seriously damaged by malfunctions or breakdowns due to the effects of large energy pulses. For electronic devices, a means for protecting against external unexpected electromagnetic pulses is required.

On the other hand, in addition to the server room, a protective means for protecting electronic equipment and communication equipment, which are also used in military units, national institutions, various industrial research institutes, hospitals, and the like, was required. And, the electronic equipment protection rack to add the function to protect the electromagnetic pulse to the rack for protecting the electronic equipment.

In general, a rack for protecting electronic equipment is provided with an accommodation space in which electronic equipment is disposed, and a door for opening or closing the accommodation space is provided, and the front or part of the door is made of transparent tempered glass.

Therefore, in order to check the state of the electronic equipment disposed in the conventional electronic equipment protection rack, the administrator moved to the corresponding electronic equipment protection rack and visually checked or opened the door, where the improved technology is an electronic equipment protection rack. Alternatively, a temperature sensor, a humidity sensor, a pollution detection sensor, and the like are placed in a server room in which the rack for protecting the electronic equipment is disposed to check whether there is an error through the information collected from the sensor.

However, a general rack for protecting electronic equipment has a problem that it is difficult to check with the naked eye because a plurality of electronic equipment is disposed therein, difficult to check in real time when an abnormality occurs, so it is difficult to prevent the spread of damage.

On the other hand, the electronic equipment protection rack used in military units uses an electronic equipment protection rack that adds a function to protect the electromagnetic pulse, which indicates that the electronic equipment is damaged even by the attack of the enemy's electromagnetic pulse that may occur in practice. It is to prevent.

However, the conventional electronic equipment protection rack has a problem that it is difficult to check with the naked eye because a plurality of electronic equipment is disposed inside the same as the rack for protecting the electronic equipment.

In addition, in the case of the rack for protecting the electronic equipment installed in the equipment that requires mobility to be used outdoors, the interior is narrow because it is designed to have only a minimum volume, a plurality of electronic equipment is arranged in a narrow interior. Therefore, there is a problem that it is difficult to visually check the operation state of the deployed electronic equipment, and because it is difficult to check the internal state of the electronic equipment protection rack, there is a problem that damage can not be confirmed in real time and spread the damage.

As shown in FIG. 11, the EMP shielding layer 70 is provided on the body 51 constituting the rack surface for protecting the electronic equipment or the signal analysis device 50 so that the EMP has an inner accommodating space of the body 51. In order not to damage the components disposed on the non-conductive film 71, a non-woven layer 72 made of a long-fiber or short-fiber nonwoven fabric attached to one surface of the non-conductive film 71, and the non-conductive It is attached to the other surface of the film 71 and has a mesh structure of 3mm to 5mm intervals, a mesh net 73 made of any one of polyester or glass fiber, and the mesh It is attached to one side of the net 73 and includes a reinforcing layer 74 made of a long fiber or short fiber nonwoven fabric and a gel-like filler 75 impregnated in the nonwoven fabric layer 72 and the reinforcing layer (74).

The non-conductive film 71 is formed of any one selected from polyethylene terephthalate (PET), polypropylene, polyolefin, polyester, polystyrene, polyamide, and polycarbonate, and has a thin film having a thickness of 30 to 60 μm. As a form, it has a restoring force to easily bend or maintain its original shape by external force, prevents the penetration of moisture, and is resistant to impact and scratches.

The nonwoven fabric layer 72 is attached to one surface of the non-conductive film 71 and is made of a long fiber or short fiber nonwoven fabric and is formed of 300 g / m 2 to 500 g / m 2 of long or short fibers as a material.

At this time, it is preferable to reduce the thickness by pressing the selected material to increase the strength at the same time. This nonwoven fabric layer is a bonding medium that allows the filler 75 and the nonconductive film 71 to be integrated with each other.

In this case, the nonwoven fabric layer 72 may be attached by heat while being pressed against the non-conductive film 71, but is not limited thereto.

The mesh net 73 is attached to the other surface of the non-conductive film 71, that is, the non-woven fabric layer 72, and is formed at intervals (sizes) of 3 mm to 5 mm, and a reinforcing layer 74 to be described later. It is a medium which makes the nonelectroconductive film 71 integrate with each other.

On the other hand, the mesh net 73 is a lifting phenomenon in the process of hardening the filler material 75 is impregnated in the mesh net to improve the tensile strength by mixing at least one of the warp and the weft yarn at least one strand of a metallic material It is desirable to prevent this from occurring.

The reinforcing layer 74 is attached to one surface of the mesh net 73 and is made of a long fiber or short fiber nonwoven fabric, and formed to have a relatively low density compared to the nonwoven fabric layer 72 to impregnate the filler 75 Or it is easier to penetrate, and the integral attachment function with the non-conductive film 71 by the mesh is maintained. This reinforcing layer 74 is composed of a long fiber or short fiber nonwoven fabric of 100g / ㎡ ~ 200g / ㎡.

The filler 75 is impregnated in the nonwoven fabric layer 72 and the reinforcement layer 74, each layer after being applied to the nonwoven fabric layer 72 and the reinforcement layer 74 while maintaining a gel (gel) state is formed in a semi-solid form Penetrates into the fine gaps of the nonwoven fabric.

When the filler 75 has a gap between the body 51 and the shielding layer 70 in a state in which it is attached to the body 51, the EMP shielding layer 70 fills the gap while filling the gap with the body 51. ) To prevent them from escaping.

The filler 75 is a low density polyethylene (LDPE) having a melt index of at least 0.5 g / 10 min and a density of 0.910 to 0.914 g / cm 3 and a high density having a melt index of at least 0.5 g / 10 min and a density of 0.958 to 0.960 g / cm 3. Polyethylene (HDPE) is blended in a weight ratio of 1: 5 to 1:10.

The low density polyethylene is excellent in workability because of its low density, and the high density polyethylene is excellent in impact resistance. The shielding function was also found to be excellent.

In particular, in the combination of the low-density polyethylene and the high-density polyethylene, it has been shown that workability is greatly improved by blending polyethylene having the above physical properties.

In the filler, when the content of the low density polyethylene and the high density polyethylene is different, if the content of the low density polyethylene is too small, the fluidity decreases during the extrusion process, resulting in an increase in the defective rate of the product, and the content of the low density polyethylene When too much, the impact resistance is lowered and the physical properties are lowered, and at the same time, the electromagnetic shielding performance is also lowered.
