본 발명은 대전현상방지를 위한 정전유도 차폐용 방수시트에 관한 것으로, 더욱 상세하게는 정전기 방지 및 전기장에 의한 유도전류 차폐능이 우수한 대전 방지용 차폐포를 포함하는 방수시트에 관한 것이다. The present invention relates to an electrostatic induction shielding waterproof sheet for preventing electrostatic phenomena, and more particularly, to a waterproof sheet including an antistatic shielding cloth having excellent antistatic and electric current shielding ability by an electric field.

최근 고유가 시대를 맞이하면서, 전기 바닥 난방에 대한 관심이 커지고 있 다. 전기 바닥난방의 방식으로는 니크롬선 등의 발열선을 이용한 선상발열체 방식과 카본 미세사 및 카본 미세 분말등을 도포하여 제작한 면상발열체 등이 있으며, 이러한 전기 난방방식은 온도조절이 용이하고, 공기가 오염되지 않으며, 위생적이고, 소음이 없으며, 빠른 발열 특성과 원적외선 방출 특성 등으로 인해 최근 각광 받고 있는 전기 난방 방식으로 자리잡고 있다. 이러한 장점들로 인해 최근에는 아파트, 일반주택, 펜션 등의 주거용 난방장치 상업용 건물의 난방장치, 작업장이나 창고, 막사 등의 산업용 난방장치, 농업용 난방장치 등에 널리 사용되고 있으며, 특히 최근에는 전기 난방의 장점을 최대로 누릴 수 있는 형태로 탄소가 지닌 자체 저항을 이용한 면상발열체의 개발과 응용이 활발하게 진행되고 있다.With the recent high oil price era, interest in electric floor heating is increasing. Electric floor heating methods include a linear heating element using a heating wire such as nichrome wire and a planar heating element made by coating carbon fine sand and carbon fine powder. Due to its non-polluting, hygienic, no-noise, fast heat-generating properties and far-infrared emission characteristics, it is becoming an electric heating method that has recently been in the spotlight. Due to these advantages, recently, residential heating devices such as apartments, general houses, pensions, etc. are widely used for heating of commercial buildings, industrial heating such as workshops, warehouses, barracks, and agricultural heating devices. The development and application of planar heating elements using the self-resistance of carbon in the form that can enjoy the maximum is actively underway.

그러나 전기 바닥 난방은 많은 장점에도 불구하고, 전기를 사용하는 그 특성상 정전기 및 전기장에 의한 유도전류가 필연적으로 발생하게 되며, 발생된 정전기 및 전기장에 의한 유도전류는 실생활에서 인간에게 많은 불쾌감을 유발할 뿐만 아니라, 건강에도 유해하다고 알려져 있어 심리적 공포감을 야기시키고 있다. However, despite the many advantages of electric floor heating, due to the nature of using electricity, induction currents due to static electricity and electric fields inevitably occur, and the induced currents caused by static electricity and electric fields not only cause a lot of discomfort to humans in real life. Rather, it is known to be harmful to health, causing psychological fear.

정전기, 전기장에 의한 유도 전류와 밀접한 관계가 있는 정전유도에 의한 대전현상은 위치별 전위차에 의해 발생되기 때문에 전위차가 발생된 위치를 서로 통전시키는 대전 방지 처리로 쉽게 제거할 수 있다는 사실이 알려져 있다. It is known that the charging phenomenon due to electrostatic induction, which is closely related to the induced current due to static electricity and electric field, is caused by the potential difference for each position, and thus can be easily removed by an antistatic treatment for energizing the positions where the potential difference occurs.

상기 사실에 기초하여, 최근에는 전기난방이 갖는 문제점들을 해결하기 위하여, 전기 열선 및 면상발열체 시공 시, 시공면 위에 도전성을 띄는 차폐막이나 차폐포를 올려놓아 위치 별 전위차를 제거함으로써, 전전현상을 방지하고, 그 결과 전기장에 의한 유도전류를 제거하는 방법이 이용되고 있으며, 또한 차폐막 혹은 차 폐포를 접지시킴으로써, 전기열선 및 면상발열체 상의 정전기를 방지시키는 방법이 주로 사용되고 있다. Based on the above facts, in order to solve the problems of electric heating in recent years, when installing electric heating wires and planar heating elements, by placing a conductive shielding film or a shielding cloth on the construction surface to remove the potential difference by position, to prevent electric phenomenon As a result, a method of removing an induced current by an electric field is used, and a method of preventing static electricity on an electric heating wire and a planar heating element is mainly used by grounding a shielding film or a shield.

그러나 면상발열체의 경우 열선 등의 선상발열체와는 다르게 전면 발열방식을 채택하여 통전 면적이 넓고 습기에 취약하고, 기계적 손상발생확률이 높아, 차폐포를 시공하기 전에 견고한 방수 시트를 이용하여 방수, 방호처리를 실시할 필요가 있다. 이에 따라 방수 공사 후 차폐포를 시공하게 되는데, 통상의 차폐포로 사용되는 금속사 직물은, 직물의 특징상 고정이 어렵고, 콘크리트 및 접착제 타설시 형태 안정성이 좋지 못하여 시공상의 많은 문제점을 지니게 된다. However, in the case of planar heating elements, unlike the linear heating elements such as heating wires, the front heating method is adopted so that the energizing area is wide, vulnerable to moisture, and the probability of mechanical damage is high. It is necessary to perform the process. Accordingly, the construction of the shielding fabric after the waterproof construction, the metal yarn fabric used as a conventional shielding fabric, it is difficult to fix due to the characteristics of the fabric, and has a lot of problems in construction due to poor shape stability when pouring concrete and adhesive.

따라서, 본 발명은 전기바닥난방에 있어 대전현상을 제거하여 인간에게 불쾌감과 건강에 해악을 끼치는 정전기와 전기장에 의한 유도전류를 제거하면서도 시공의 편의성을 도모할 수 있도록 하기 위하여 차폐포를 방수시트와 일체화한 제품을 제공하는 것을 목적으로 한다. Therefore, the present invention is to remove the charging phenomenon in the electric floor heating to remove the induced current caused by static electricity and electric field harmful to humans unpleasant and health, and to facilitate the construction of the shielding cloth with a waterproof sheet and It is an object to provide an integrated product.

상기한 목적을 달성한 본 발명에 의하면, 정전유도 차폐용 방수시트에 있어서, 금속사 직물 차폐포와, 상기 차폐포의 일면 또는 양면에 방수시트가 합지된 것을 특징으로 하는 정전유도 차폐용 방수시트가 제공된다. According to the present invention to achieve the above object, in the electrostatic induction shielding waterproof sheet, the electrostatic induction shielding waterproof sheet, characterized in that the waterproofing sheet is laminated on one or both sides of the metal yarn fabric shielding cloth and the shielding fabric is Is provided.

또한 본 발명에 의하면, 상기 차폐포의 양면에 방수시트가 합지되고, 상기 방수시트들중 어느 한 방수시트 위에 부직포가 합지된 것을 특징으로 하는 정전유도 차폐용 방수 시트가 제공된다. According to the present invention, there is provided a waterproof sheet for electrostatic induction shielding, characterized in that the waterproof sheet is laminated on both sides of the shielding cloth, and the nonwoven fabric is laminated on any one of the waterproof sheets.

또한 본 발명에 의하면, 상기 차폐포의 한 끝단 또는 양 끝단에 접지접속을 위한 리드선이 연결된 것을 특징으로 하는 정전 유도 차폐용 방수 시트가 제공된다. In addition, according to the present invention, there is provided a waterproof sheet for electrostatic induction shielding, characterized in that a lead wire for ground connection is connected to one or both ends of the shielding cloth.

이하, 본 발명을 보다 상세하게 설명하기로 한다. Hereinafter, the present invention will be described in more detail.

본 발명에 따르는 정전유도 차폐용 방수시트에 있어서, 금속사 직물 차폐포와, 상기 차폐포의 일면 또는 양면에 방수시트가 합지된 구조를 갖는다. In the electrostatic induction shielding waterproof sheet according to the present invention, a metal yarn fabric shielding fabric and a waterproof sheet are laminated on one or both surfaces of the shielding fabric.

Preferred examples of the metal yarns that can be used to prepare the metal yarn fabric shielding fabric include copper yarns, stainless yarns, silver yarns, gold yarns, wires, zinc yarns, tin yarns or a mixture of two or more thereof.

상기 금속사 직물 차폐포는 금속사 만으로 제조할 수도 있으나, 금속사를 천연섬유사, 합성섬유사 등과 혼직하여 제조할 수도 있다. 이러한 천연 또는 합성 섬유사의 바람직한 예로는 폴리에칠렌사, 폴리프로필렌사, 폴리에스터사, 아크릴사, 면사, 나일론사 등이 있다. The metal yarn fabric shielding fabric may be made of only metal yarn, but may also be mixed by mixing the metal yarn with natural fiber yarn, synthetic fiber yarn and the like. Preferred examples of such natural or synthetic fibers include polyester, polypropylene, polyester, acrylic, cotton, nylon and the like.

금속사 직물 차폐포는 그 두께가 지나치게 얇거나 두꺼우면 방수시트와의 합지가 곤란하게 되거나 정전유도 차폐효과가 미흡하게 될 수도 있으며 난방효과를 떨어뜨릴 수가 있다. 금속사 직물 차폐포의 두께 0.05 ~ 3mm의 범위내에서는 방수시트와의 합지가 용이하고 정전유도 차폐효과 및 난방효과도 우수하게 되므로 상기 한 범위내로 차폐포의 두께를 조절하는 것이 바람직하다. Metal yarn fabric shielding cloth is too thin or too thick, it is difficult to combine with the waterproof sheet or the electrostatic induction shielding effect may be insufficient and may reduce the heating effect. Within the range of 0.05 to 3 mm in thickness of the metal yarn fabric shielding cloth, it is preferable to adjust the thickness of the shielding cloth within the above range because the lamination with the waterproof sheet is easy and the electrostatic induction shielding effect and the heating effect are also excellent.

또한 금속사 직물 차폐포에 이용되는 금속사나 합성섬유사의 중량단위가 100 ~ 3000 데니어가 되도록 하는 것이 바람직하다. In addition, it is preferable that the weight unit of the metal yarn or synthetic fiber yarn used for the metal yarn fabric shielding cloth is 100 to 3000 denier.

또한, 금속사 직물 차폐포는 그 직조 밀도로 위사가 인치당 1~100, 경사가 인치당 1~100인 것이 바람직하다. In addition, it is preferable that the weft density of the metallic yarn fabric shielding fabric is 1-100 per inch, and the inclination is 1-100 per inch by the weave density.

금속사 직물 차폐포의 일 끝단 또는 양 끝단에는 리드선을 형성시켜 접지접속을 용이하게 하는 것이 바람직하다. It is preferable to form a lead wire at one or both ends of the metal yarn fabric shielding fabric to facilitate ground connection.

본 발명의 정전유도 차폐용 방수시트에서 차폐포와 합지되는 방수시트의 재질로는 아스팔트, 부틸합성고무, 부타디엔 합성고무, 니트릴 합성고무, 천연고무 등이 바람직하다. As the material of the waterproof sheet laminated with the shielding cloth in the waterproof sheet for electrostatic induction shielding of the present invention, asphalt, butyl synthetic rubber, butadiene synthetic rubber, nitrile synthetic rubber, natural rubber, and the like are preferable.

방수시트는 그 두께가 지나치게 얇거나 두꺼우면 차폐포와의 합지가 곤란하게 되거나 방수효과가 미흡하게 될 수도 있으며 난방효과를 떨어뜨릴 수가 있다. 방수시트의 두께 0.1 ~ 10mm의 범위내에서는 차폐포와의 합지가 용이하고 방수효과 및 난방효과도 우수하게 되므로 상기한 범위내로 방수시트의 두께를 조절하는 것이 바람직하다. If the thickness of the waterproof sheet is too thin or too thick, it may be difficult to combine with the shielding cloth, or the waterproof effect may be insufficient, and the heating effect may be reduced. Within the range of the thickness of the waterproof sheet is 0.1 ~ 10mm it is preferable to adjust the thickness of the waterproof sheet within the above range because it is easy to be laminated with the shielding cloth and excellent waterproof effect and heating effect.

본 발명에서 제공하는 차폐용 방수 시트는 차폐포의 일체화 과정 및 위치에 따라 2가지 형태, 즉 함침형과 표면형으로 나눌 수 있다. 이를 첨부도면을 참조하여 설명하면 다음과 같다.

It is possible to improve the bonding force with the back. Polyester, cotton, glass, polypropylene is suitable as the material of the nonwoven fabric 4 laminated on the upper surface of the waterproof sheet 3 in the impregnation type, and the weight per area of the nonwoven fabric is 5 to 500 g / m 2.
