본 고안은 면상발열체에 관한 것으로, 더욱 상세하게는 원적외선을 다량으로 방사하고 난방에 이용되는 면상발열체로서, 통상의 인쇄원단인 절연성베이스원단, 저항에 의해 발열기능을 하는 카본발열부, 상기 카본발열부의 양단에 금속성잉크로 인쇄 형성시킨 제2도전층, 물리적인 충격으로 동박전극에 의해 제2도전층과 카본발열부가 손상되지 않도록 상기 제2도전층과 동박전극 사이에 형성되는 손상방지절연층 또는 전류의 통전 및 동박전극에 의한 손상이 되지 않도록 제2도전층으로부터 이격된 동박전극과 제2도전층 상부에 적층되어 형성되는 손상방지도전층, 원거리까지 전류를 공급하도록 형성되는 동박전극, 상기 절연성베이스원단을 밀폐시키도록 합지되는 코팅지를 포함하는 면상발열체에 관한 것이다.The present invention relates to a planar heating element, and more particularly, a planar heating element which emits a large amount of far-infrared rays and is used for heating, an insulating base fabric which is a normal printing fabric, a carbon heating unit that generates heat by resistance, and the carbon heating unit A second conductive layer formed by printing a metallic ink on both ends of the negative portion; a damage preventing insulating layer formed between the second conductive layer and the copper foil electrode such that the second conductive layer and the carbon heating portion are not damaged by the copper foil electrode due to a physical impact; or The copper foil electrode spaced apart from the second conductive layer and the damage prevention conductive layer formed by being stacked on the second conductive layer so as not to be damaged by the current supply and the copper foil electrode, and the copper foil electrode formed to supply current to a long distance, the insulating property It relates to a planar heating element comprising a coated paper laminated to seal the base fabric.

일반적으로, 기온이 낮은 동절기 바닥 난방용이나 생물의 발아촉진용, 도로 융설용 등 발열을 요하는 장소나 제품에 면상발열체가 이용되고 있다.In general, planar heating elements are used in places and products that require heat, such as for heating floors at low temperatures in winter, for promoting germination of living organisms, and for melting roads.

종래의 면상발열체로 2004년 10월 28일 출원된 실용신안출원번호 제20-2004-0030553호와 같이 절연성이 우수한 절연필름의 상면에 고저항체인 액상의 카본페이스트를 적당한 간격을 두고 도포하여 카본발열부를 형성한 후에, 카본부의 양단에 각각 열전도를 향상시키기 위해 도전성의 실버페이스트를 도포하여 실버부를 형성하는 것과 동시에 카본발열부가 균일하게 발열되도록 상기 카본발열부의 양단끝을 따라 실버라인을 형성한 다음, 실버부에 구리박판(동박전극)을 대고, 절연필름을 코팅시켜 제조된다.As a conventional planar heating element, a high-resistance liquid carbon paste is applied on the upper surface of an insulating film having excellent insulation, such as Utility Model Application No. 20-2004-0030553, filed on October 28, 2004, at an appropriate interval, thereby generating carbon. After forming the portion, to form a silver portion by applying a conductive silver paste on both ends of the carbon portion to improve the thermal conductivity, respectively and at the same time to form a silver line along both ends of the carbon heat generating portion so that the carbon heat generating portion uniformly It is manufactured by coating an insulating film on a silver foil (copper foil electrode).

상기한 종래의 통상적인 면상발열체는 전류를 동박전극(구리박판)에서 카본발열부로 원활히 공급되도록 전도성이 우수한 실버부를 적용하고 있으나, 상기 실버부의 상부에 접촉되도록 적층되는 동박전극의 모서리부가 물리적으로 짓눌릴 경우 실버부를 손상시켜 카본발열부와 접촉됨에 따라 동박전극과 카본발열부 간에 전기적인 쇼트현상이 발생되어 화재로 이어지는 문제점을 가지고 있다.The conventional planar heating element of the related art applies a silver portion having excellent conductivity so that electric current is smoothly supplied from the copper foil electrode (copper thin plate) to the carbon heating portion, but the edge portion of the copper foil electrode laminated to contact the upper portion of the silver portion is physically crushed. In case of reel, as the silver part is damaged and the carbon heat generating part is in contact, electrical short phenomenon occurs between the copper foil electrode and the carbon heat generating part, which leads to a fire.

또한, 상기와 같이 동박전극의 모서리에 의해 실버부 및 카본발열부가 손상되는 것을 방지하도록 본 고안자가 2007년 2월 28일 출원한 대한민국 실용신안등록출원번호 제20-2007-003632호와 같이 손상방지층을 실버부와 동박전극 사이에 절연성원단을 소정의 폭으로 형성시켜 실버부의 손상을 방지하였으나, 손상방지층을 구성하는 절연성원단의 가공하는 비용이 상승되고, 손상방지층을 적용하기 위해 코팅기의 구조를 전면적으로 바꿔야하는 문제점과 실버부의 상부에 적용 시 불량률이 많아져 제조단가가 상승되는 문제점이 있었다. 또한, 동박전극이 실버부(제2도전층)이 상부에 적층되지 않고 이격되어 동박전극에 의한 실버부(제2도전층)의 손상을 제거하도록 동박전극이 실버부(제2도전층)로부터 이격된 구조가 요구된다.In addition, the damage prevention layer as described in Korean Utility Model Registration No. 20-2007-003632 filed February 28, 2007 to prevent the silver portion and the carbon heat generating portion is damaged by the edge of the copper foil electrode as described above In order to prevent damage to the silver part by forming an insulating fabric between the silver part and the copper foil electrode in a predetermined width, the cost of processing the insulating fabric constituting the damage prevention layer is increased, and the structure of the coating machine is applied to apply the damage prevention layer. There was a problem in that the manufacturing cost is increased due to the problem that should be replaced with the defect rate increases when applied to the upper portion of the silver. In addition, the copper foil electrode is separated from the silver portion (second conductive layer) without being stacked on top so that the copper foil electrode is separated from the silver portion (second conductive layer) so as to eliminate the damage of the silver portion (second conductive layer) by the copper foil electrode. Spaced structures are required.

따라서 본 고안은 전기한 바와 같은 문제점을 해결하기 위한 것으로서, 카본발열부의 양단에 전류를 원활히 공급되도록 구성되는 제2도전층을 구성시키고, 열가소성수지 또는 열경화성수지로 인쇄 형성되는 손상방지절연층 또는 제2도전층으로 부터 일정거리가 이격 되는 동박전극에서 상기 제2도전층으로 통전이 되어지도록 상기 동박전극과 제2도전층 상부에 손상방지도전층을 적층시켜, 제2도전층과 카본발열부가 손상되지 않고 안정적으로 장기간 사용할 수 있는 면상발열체를 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the problems as described above, and constitute a second conductive layer configured to smoothly supply current to both ends of the carbon heat generating portion, and the damage prevention insulating layer or the printed material formed of thermoplastic resin or thermosetting resin A damage preventing conductive layer is laminated on the copper foil electrode and the second conductive layer so as to conduct electricity from the copper foil electrode spaced a predetermined distance from the second conductive layer to the second conductive layer, thereby damaging the second conductive layer and the carbon heating portion. The purpose is to provide a planar heating element that can be used stably for a long time.

대한민국 실용신안등록번호 제20-0341343호와 대한민국 실용신안등록 번호 제20-0100534대한민국 특허등록번호 제10-0468651, 대한민국 실용신안 등록번호 제20-0408349, 20-0433719, 20-0375245호 등에는 저항열에 의해 발열되는 카본발열부의 양단에 전도성이 우수하면서 동박전극과 접촉에 따른 스파크현상을 제거하도록 실버부를 형성한 후 도전성점착제나 열에 의해 녹는 핫멜트접착제가 형성된 구리박판이 적용된 면상발열체가 개발되었다. 종래의 면상발열체 중 도전성점착제를 이용한 경우 열에 의해 점착제의 성분이 열적 변화되어 점착력이 떨어지는 문제점이 생겼으나, 이를 보완하기 위해 더욱 발전된 도전성 핫멜트접착제가 개발되었다. 이러한 상기 핫멜트접착제는 종래 전도성점착제에 비해 접착력이 뛰어나 안전성이 더욱 안정되었으나 중저온 열에 의해 변형되는 특성을 갖는 핫멜트수지는 카본발열부에서 발생된 열과 물리적인 충격에 의해 쉽게 변형되기 쉬워 도전성을 갖는 핫멜트접착제의 저항이 불안정한 문제점을 가지고 있다.Resistance to Korea Utility Model Registration No. 20-0341343 and Korea Utility Model Registration No. 20-0100534 Korea Patent Registration No. 10-0468651, Korea Utility Model Registration No. 20-0408349, 20-0433719, 20-0375245 The planar heating element was developed by applying a copper plate formed with a conductive adhesive or a hot melt adhesive melted by heat after forming a silver part to have excellent conductivity at both ends of the heat generated carbon heat generating part and to remove spark phenomenon caused by contact with the copper foil electrode. In the case of using a conductive adhesive among the conventional planar heating elements, the components of the adhesive are thermally changed due to heat, resulting in a problem in that the adhesive strength is lowered, but a more advanced conductive hot melt adhesive has been developed to compensate for this. The hot melt adhesive has better adhesive strength than the conventional conductive adhesive, which is more stable. However, the hot melt resin having a property of being deformed by low and low temperature heat is easily deformed by heat and physical impact generated in the carbon heating unit, and has a hot melt. The adhesive's resistance is unstable.

The conductive adhesive layer 155 may be formed on one or both surfaces of the damage preventing insulating layer 130 or the damage preventing conductive layer 160 using a one-component or two-component synthetic resin in which a curing reaction is caused by a curing agent. In addition, after mixing a predetermined amount of the hot-melt resin and the curable resin may be added to the conductive powder and the curing agent to form a conductive adhesive layer 155 that can increase the adhesive strength.

상기 경화반응이 일어나는 1액형 또는 2액형 합성수지는 경화반응 되는 수지에 전도성분말과 경화제 및 용제 등을 소정의 양으로 투입 혼합한 후 일정한 두께로 손상방지도전층(160)의 단면 또는 양면에 형성한다. 상기와 같이 형성된 손상방지도전층(160)을 제2도전층(120)과 동박전극(140) 사이에 형성시킨 후 일정시간동안 경화시켜 카본발열부(115)에서 발생된 열이나 외부의 열에 의해 상기 제2도전층(120)에서 동박전극(140)이 이탈되거나 박리되지 않고, 물성 또한 변형이 없이 안정된 저항을 유지할 수 있는 효과가 있다.The one-component or two-component synthetic resin in which the curing reaction occurs is mixed with a conductive powder, a curing agent and a solvent in a predetermined amount into the resin to be cured, and then formed on one or both sides of the damage preventing conductive layer 160 in a predetermined thickness. . The damage preventing conductive layer 160 formed as described above is formed between the second conductive layer 120 and the copper foil electrode 140 and then cured for a predetermined time by heat generated from the carbon heat generating unit 115 or external heat. The copper foil electrode 140 is not separated or peeled off from the second conductive layer 120, and there is an effect of maintaining a stable resistance without physical properties and deformation.

The copper foil electrode and the second conductive layer are stacked on top of each other to prevent damage to the carbon heating unit and the second conductive layer, and at the same time, it is possible to provide a planar heating element which can be safely used for a long time by smoothly conducting current.
