상기 절연성베이스원단(102)은 면상발열체(100)에 전원을 통전 시 자체적으로 발생되는 고온열에 견딜 수 있도록 내열성과 장기간 사용을 하기 위해 누전이나 물리적인 충격에 견딜 수 있는 절연성베이스원단(102)을 이용하여야 한다. 면상발열체(100)를 일반적으로 사용하는 온도는 상온 20~100℃내외로서 주로 난방용이나 찜질용으로 사용되고 있다. 상기와 같은 온도에 내열성을 갖는 절연성베이스원단(102)으로는 PET, PE, 폴리우레탄, 에폭시 원단 및 열접착성, 전기절연성, 난연성, 내굴곡성 및 접착제의 흐름성이 균일한 폴리이미드원단 등을 이용할 수 있으며, 가장 바람직하게는 PET를 사용하도록 한다. 이러한 상기 원단은 제조 시 자체적으로 형성된 미세 기공이 존재하는데, 이와 같은 기공을 통해 습기가 투습하여 저항발열부인 카본부와 실버부 및 합지되는 열가소성 코팅지(114)면의 접착력에 영향을 주어 카본(115)과 실버(118) 및 코팅지(114)의 열가소성수지층(125)이 습에 의해 박리되는 현상이 일어난다. 상기와 같은 문제점을 방지하기 위해 절연성베이스원단(102)의 인쇄되는 면에 코로나방전(110)을 시켜 카본부(115)와 실버부(118) 및 코팅지(114)가 접착이 우수하도록 처리된다. 코로나방전(110)이란 2개의 전극사이에 높은 전압을 가하면, 불꽃을 발하기 이전에 전기장의 강한 부분만이 발광하여 전도성을 갖는 현상을 말한다. 2개의 전극이 모두 평판 또는 지름이 큰 구와 같은 경우의 전기장은 거의 균일하지만, 한쪽 극 또는 양극이 봉상 또는 침상으로 되어 있으면, 그 극 부근의 전기장이 특히 강해져 부분적인 방전이 일어나 빛이나 소리를 낸다. 이와 같은 상태를 코로나 방전(110)이라고 하는데, 상기와 같이 절연성베이스 원단(102)의 인쇄면을 코로나 방전(110) 시킬 경우 상기 인쇄면에 코로나 방전(112)에 의한 요철이 발생되며, 여기에 프라이머 코팅층(113)을 형성시킨 절연성베이스원단(102)이 형성된다.The insulating base fabric 102 is an insulating base fabric 102 that can withstand a short circuit or physical shock for heat resistance and long-term use to withstand the high temperature heat generated when power is supplied to the planar heating element 100 Should be used. The temperature generally using the planar heating element 100 is about 20 ~ 100 ℃ room temperature is mainly used for heating or steaming. As the insulating base fabric 102 having heat resistance at the above temperature, PET, PE, polyurethane, epoxy fabric and polyimide fabric having heat adhesiveness, electrical insulation, flame retardancy, flex resistance, and flowability of the adhesive are uniform. It is available, and most preferably to use PET. The fabric has micro pores that are formed by itself during manufacturing, moisture is permeated through such pores to affect the adhesion of the carbon portion, the silver portion and the surface of the thermoplastic coated paper 114 to be laminated with the heat resistance resistance carbon (115) ) And the thermoplastic resin layer 125 of the silver 118 and the coated paper 114 is peeled off by moisture. In order to prevent the above problems, the carbon portion 115, the silver portion 118 and the coated paper 114 are treated to have excellent adhesion by making a corona discharge 110 on the printed surface of the insulating base fabric 102. Corona discharge 110 refers to a phenomenon in which when a high voltage is applied between two electrodes, only a strong portion of the electric field emits light before conducting a spark and has conductivity. The electric field is almost uniform when both electrodes are flat plates or spheres with large diameters, but if one pole or anode is rod-shaped or needle-shaped, the electric field near that pole is particularly strong, resulting in partial discharge resulting in light or sound. . Such a state is referred to as corona discharge 110, when the corona discharge 110 to the printing surface of the insulating base fabric 102 as described above, irregularities are generated by the corona discharge 112 on the printing surface, An insulating base fabric 102 having the primer coating layer 113 formed thereon is formed.

상기와 같이 절연성베이스원단(102)의 내면에 형성되는 프라이머 코팅층(113)은 아크릴계수지, 폴리에틸렌계수지, 폴리우레탄계수지, 폴리염화비닐계수지 중 1종 또는 1종 이상을 혼용하여 제작되는 합성수지로 형성하되, 두께는 0.5∼50㎛로 도포하여 형성하고, 바람직하게는 2∼5㎛의 두께로 도포하여 형성한다.As described above, the primer coating layer 113 formed on the inner surface of the insulating base fabric 102 is a synthetic resin produced by mixing one or more kinds of acrylic resins, polyethylene resins, polyurethane resins, and polyvinyl chloride resins. It is formed, but the coating is formed by applying a thickness of 0.5 to 50㎛, preferably by applying a thickness of 2 to 5㎛.

한편, 카본부(115)는 저항열에 의해 발열기능을 갖도록 일정한 패턴을 유지하여 프라이머코팅층(113)에 액체상태의 카본페이스트를 도포 건조한다. 이러한 카본페이스트의 수지성분은 절연성베이스원단(115)에 코팅된 프라이머코팅층(113)과 동일한 계통의 수지인 카본페이스트를 사용하도록 한다.On the other hand, the carbon portion 115 is dried by applying a liquid carbon paste to the primer coating layer 113 by maintaining a constant pattern to have a heat generating function by the heat of resistance. The resin component of the carbon paste is to use the carbon paste, which is a resin of the same type as the primer coating layer 113 coated on the insulating base fabric 115.

실버부(118)는 절연성베이스원단(102)에 인쇄된 카본부(115)의 양단 끝에 일정한 간격을 유지하여 인쇄 건조되며, 통전되는 전류를 카본부(115)로 접촉저항이 없이 원활히 전달하는 역할을 한다. 이러한, 상기와 같은 카본부(115)와 실버부(118)는 1°카본인쇄와 2°실버인쇄가 상호 바뀌어도 무방하다.The silver part 118 is printed and dried by maintaining a constant gap at both ends of the carbon part 115 printed on the insulating base fabric 102, and smoothly transmits the current to the carbon part 115 without contact resistance. Do it. In the carbon portion 115 and the silver portion 118 as described above, 1 ° carbon printing and 2 ° silver printing may be interchanged.

그리고, 금속전극(120)은 상기 실버부(118)와 접촉되도록 실버(118) 상부에 중첩시켜 공급되는 전류를 원거리의 실버부(118)까지 저항을 최소화하여 카본부(115) 전체에서 동일한 발열성능을 갖도록 형성된다. 상기 금속전극(120)의 재질로 는 동박판이나 알루미늄박판 또는 동이나 알루미늄을 주석으로 도금한 금속박판을 이용하며, 통전 시 실버부(118)의 원거리까지 전류의 저항을 최소화 시켜 카본부(115)에 전류를 원활히 전달함으로써 고온의 발열을 이루게 하는 역할을 한다.In addition, the metal electrode 120 overlaps the upper portion of the silver 118 so as to be in contact with the silver portion 118, thereby minimizing the resistance to the silver portion 118 of the distant portion. It is formed to have performance. As the material of the metal electrode 120, a copper plate or an aluminum plate, or a metal plate plated with copper or aluminum with tin, is used, and minimizes the resistance of the electric current to a long distance of the silver unit 118 when energizing the carbon unit 115. ) Makes the heating of high temperature by transferring the current smoothly.
