Description

기능성 면상발열체{Functonal sheet type heating element}Functional sheet heating element {Functional sheet type heating element}

본 발명은 기능성 면상발열체에 관한 것으로, 보다 상세하게는 탄소도전체로 이루어진 방열층을 포함하는 면상발열체에 실리카블랙 및 단열재료 중 적어도 어느 하나를 포함함으로써 원적외선 방출 또는 단열효과를 갖는 면상발열체에 관한 것이다.The present invention relates to a functional planar heating element, and more particularly, to a planar heating element having a far-infrared emitting or heat insulating effect by including at least one of silica black and a heat insulating material in a planar heating element including a heat radiation layer made of a carbon conductor. will be.

일반적으로 면상발열체는 발열률이 우수하고, 온도조절이 용이할 뿐 아니라 소음이 거의 없어 가정용 및 산업용으로 다양한 분야에 적용되고 있다.In general, planar heating elements have excellent heating rate, easy temperature control, and almost no noise, so they are being applied to various fields for home and industrial use.

이러한 면상발열체는 얇은 면상의 전도성 발열체 양단에 금속 전극을 설치하고 절연재로 절연 처리한 후 금속 전극에 정격 전압을 인가하면 면 전체에서 발열이 이루어지게 된다. 이러한 면상발열체의 전극은 은, 구리 등이 이용되고, 탄소로 구성된 발열체로는 카본 페이스트, 카본 섬유 등이 이용되고 있다.In such a planar heating element, when metal electrodes are installed on both ends of a thin conductive heating element, insulated with an insulating material, and then a rated voltage is applied to the metal electrode, heat is generated over the entire surface. For the electrode of such a planar heating element, silver, copper, etc. are used, and carbon paste, carbon fiber, etc. are used as a heating element composed of carbon.

종래기술에 따른 면상발열체는 지속적인 발열과 외부 힘에 의한 발열 구조의 손상으로 화재의 위험이 높고, 발열 효율의 저하가 발생되고 있어 면상발열체가 대안으로 제시되고 있으나, 면상발열체는 전기를 사용하는 특성상 정전기 및 전기장에 의한 유도전류가 필연적으로 발생하게 되며, 발생된 정전기 및 전기장에 의한 유도전류는 실생활에서 불쾌감을 유발할 뿐만 아니라, 건강에도 유해하다고 알려져 있어, 면상발열체 사용의 기피 요인으로 자리 잡고 있다.The planar heating element according to the prior art has a high risk of fire due to continuous heat generation and damage to the heating structure by external forces, and a decrease in heating efficiency is occurring. Induction current by static electricity and electric field inevitably occurs, and induced current by static electricity and electric field generated not only causes discomfort in real life, but is also known to be harmful to health, so it is positioned as a factor to avoid using planar heating elements.

이러한 단점을 해결하기 위해 면상발열체 위에 도전성을 띄는 차폐막이나 차폐포를 올려놓아 위치별 전위차를 제거함으로써 대전현상을 방지 및 절연효과를 나타내는 방법이 이용되고 있으나, 위치가 변경되거나 그 기능이 상실되는 등 문제가 발생하고 있다.In order to solve this drawback, a method is used to prevent the charging phenomenon and to show an insulating effect by placing a conductive shielding film or shielding cloth on the planar heating element to remove the potential difference by position, but the position is changed or its function is lost, etc. A problem is occurring.
