본 발명은 외부 충격을 흡수하면서 전자파를 감지하여 그 위치를 파악할 수 있는 시트에 관한 것으로, 특히 방습성 및 방식성이 우수하고 내구력이 향상된 충격흡수 및 전자파감지 시트에 관한 것이다.The present invention relates to a sheet that can detect the electromagnetic wave while absorbing an external impact, and to determine its position, and more particularly, to a shock absorbing and electromagnetic wave sensing sheet having excellent moisture resistance and corrosion resistance and improved durability.
일반적으로 주철 등으로 제조된 금속파이프나 합성수지로 제조된 PVC파이프를 도시가스공급관이나 수도관으로 많이 사용하고 있으나, 금속파이프를 지하에 매설할 경우 수분에 노출되어 쉽게 녹이 슬고 시공비가 비쌀 뿐 아니라 지진과 같은 외부충격에 의해 금속파이프 자체 및 그 결합부위가 쉽게 손상되므로 화재나 폭발사고 및 수재와 같은 2차적인 재난을 발생시킬 수 있는 문제점이 있었다.In general, metal pipes made of cast iron or PVC pipes made of synthetic resins are commonly used as city gas supply pipes or water pipes.However, when metal pipes are buried underground, they are easily exposed to moisture and are expensive to construct. Since the metal pipe itself and its joints are easily damaged by the same external impact, there is a problem that may cause secondary disasters such as fire, explosion, and flooding.
한편, PVC파이프는 제조 및 설치가 용이하고, 외부충격이 가해지더라도 쉽게 휘어지거나 깨지지 않으며, PVC파이프의 표면에 글자를 새겨 넣기가 용이한 반면, PVC파이프 표면에 새겨 넣은 글자가 습기에 쉽게 부식되어 손상되는 결점을 가지며, 특히, PVC파이프가 빛을 반사하지 않으므로 전자파를 사용하여 PVC파이프의 매설위치 등을 파악할 수 없는 결점이 있었다. 또한 이미 지중에 매설된 PVC파이프를 교체하거나 수리하기 위해 땅을 굴착하는 과정에서 PVC파이프 자체가 굴착기에 의해 손상되는 문제점도 있었다.On the other hand, PVC pipe is easy to manufacture and install, does not easily bend or break even when external impact is applied, and it is easy to engrave letters on the surface of the PVC pipe, whereas letters etched on the PVC pipe surface are easily corroded by moisture. There is a defect that is damaged, in particular, because the PVC pipe does not reflect light, there was a defect that can not determine the embedding position of the PVC pipe using electromagnetic waves. In addition, there is a problem that the PVC pipe itself is damaged by an excavator in the process of excavating the ground to replace or repair the PVC pipe already buried in the ground.
이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 방습성 및 방식성이 우수하고 내구력이 크게 향상되며 외부 충격에 대하여 완충작용을 수행하면서 전자파에 의해 쉽게 그 위치가 파악될 수 있는 충격흡수 및 전자파 감지 시트를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, the moisture absorption and corrosion resistance is excellent, the durability is greatly improved and the shock absorption can be easily identified by the electromagnetic wave while performing a buffer against the external impact And an electromagnetic wave sensing sheet.
상기와 같은 목적을 달성하기 위한 본 발명에 따른 충격흡수 및 전자파감지 시트는 알루미늄과 같은 금속박의 일면에 용융상태의 합성수지가 냉각압연피복되고, 이 금속박의 타면에 용융상태의 합성수지를 매개로 직교적층필름 및 발포수지층이 냉각압연적층 되는 구조로 된 것을 그 특징으로 한다.The impact-absorbing and electromagnetic wave sensing sheet according to the present invention for achieving the above object is a cold rolled synthetic resin of the molten state on one surface of a metal foil such as aluminum, orthogonal lamination through the molten synthetic resin on the other surface of the metal foil The film and the foamed resin layer are characterized by having a structure that is cold rolled laminated.

In the step of applying, the second adhesive layer 6 made of the same components as the first adhesive layer 3 is applied onto the metal foil layer 5 which has been subjected to the metal foil lamination process, and then the first metal protective layer is applied to the second adhesive layer 6.

Since it is produced in the form of coating the foamed resin layer 9 such as polyethylene, it is possible to block the moisture and air to prevent oxidation of the metal foil layer 5 in advance, and to block light by the metal foil layer 5. It can also be used as a wrapper to protect the inner package against external impacts.
또한, 금속박(5)이 금속탐지기에 의해 쉽게 탐지되므로 상기 시트(A)를 원통형시트(B)로 가공하여 지중선로, 수도관 또는 가스파이프(14)의 외부 표면을 감싼 상태에서 지중에 매설하게 되면 별도의 굴착작업없이 지상에서 금속탐지기를 사용하여 지하매설물의 위치를 정확하게 파악할 수 있으며, 발포수지층(9)이 시트(A)와 일체로 성형 부착되므로 지진이나 발파작업과 같은 외부충격이 파이프(14)에 직접 전달되는 것을 방지할 수도 있다. 금속박층(5)과 발포수지층(9) 사이에 적층되어 일체로 성형된 직교적층필름(8)은 시트(A)(B)의 인장강도를 증대시키는 한편 시트(A)(B)가 특정 방향을 따라 용이하게 절개되지 않도록 한다.In addition, since the metal foil 5 is easily detected by the metal detector, when the sheet A is processed into a cylindrical sheet B and embedded in the ground while covering the outer surface of the underground line, the water pipe, or the gas pipe 14. It is possible to pinpoint the location of underground buried material using a metal detector on the ground without any additional excavation work. Since the foamed resin layer 9 is integrally molded and attached to the sheet A, external shock such as earthquake or blasting work may be applied to the pipe ( 14) may be prevented from being delivered directly. The orthogonal laminated film 8, which is integrally formed by being laminated between the metal foil layer 5 and the foamed resin layer 9, increases the tensile strength of the sheets A and B while the sheets A and B are specified. Do not cut easily along the direction.
한편, 원통시트성형공정에 따라 제조된 원통형시트(B)를 도시가스파이프(14) 주위에 끼워 설치한 후, 원통형시트(B)의 중첩부분에 길이방향을 따라 성형된 덮개막(10)으로 절개부(15)를 덮고 상기 덮개막(10)을 시트(B)에 접착시키면, 원통형시트(B)가 파이프(14) 주위를 완전히 밀봉시키게 된다.On the other hand, after the cylindrical sheet (B) manufactured according to the cylindrical sheet forming process is fitted around the city gas pipe (14), and installed on the overlapping portion of the cylindrical sheet (B) along the longitudinal direction of the overcoat 10 By covering the cutout 15 and adhering the overcoat 10 to the sheet B, the cylindrical sheet B completely seals around the pipe 14.
또한, 합성수지 필름(1)위에 일정한 내용이 담긴 문자나 도형(2)을 인쇄하고 그 문자(2)위에 다시 합성수지로 된 금속보호층(4)을 피복하므로 문자나 도형(2)이 습기나 공기에 의해 부식·산화되는 것을 방지할 수 있다.In addition, a character or figure (2) containing a certain content is printed on the synthetic film (1), and the metal protective layer (4) made of synthetic resin is coated on the character (2) again, so that the character or figure (2) is damp or airy. Corrosion and oxidation can be prevented by
