정온 발열 소자의 제조방법 및 그의 정온 발열 소자{Method for manufacturing PTC heating element and PTC heating element thereof }Method for manufacturing a constant temperature heating element and its constant temperature heating element TECHNICAL FIELD

본 발명은 내굴곡성 있는 면상 발열소자에 정온(定溫) 기능을 부여하기 위한 것으로, 전원 인가용 편조 전극선과 발열 소자 간의 계면 층에 반도성 세라믹스 복합체로 구성되는 것에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to providing a constant temperature function to a planar heat generating element having a bend resistance, and relates to a semiconductor ceramic composite composed of an interface layer between a power supply braided electrode line and a heat generating element.

반도체란 금속과 같은 도체(전기전도도 104~106Ω-1cm-1)와 유리나 자기와 같은 절연체(전기전도도 10-20~10-12Ω-1cm-1)와의 중간의 전기전도성(예를 들면, 10-10~102Ω-1cm-1)을 갖는 물질군의 총칭이다. 단, 반도체의 특징은 전기 전도도의 크기 그 자체보다 오히려 온도 및 전압 변화나 미량의 불순물의 존재 등으로 전기적 성질이 현저하게 변화하는 것이며, 이 성질을 다양한 응용분야에 이용한다. 예를 들면 반도체는 극저온에서는 절연체에 가깝게 전기전도성을 나타내지 않지만, 온도가 상승하면 급격히 전도성을 나타내게 된다. 이것은 금속이 온도 상승에 의해 전기전도성이 감소하는 것과 대조적이다.A semiconductor is an electrical conductivity intermediate between a conductor such as a metal (electric conductivity 10 4 ~ 10 6 Ω -1 cm -1 ) and an insulator such as glass or porcelain (electric conductivity 10 -20 ~ 10 -12 Ω -1 cm -1 ) For example, 10 -10 to 10 2 Ω -1 cm -1 ) is a generic name of a group of materials. However, the characteristic of the semiconductor is that the electrical properties are remarkably changed due to temperature and voltage changes or the presence of trace impurities, rather than the magnitude of the electrical conductivity itself, and this property is used for various applications. For example, semiconductors do not exhibit electrical conductivity close to insulators at cryogenic temperatures, but become rapidly conductive when temperatures rise. This is in contrast to the decrease in electrical conductivity of metals due to temperature rise.

다음은 반도성 세라믹스로서, 현재 공업적으로 볼 때 BaTiO3는 고유전율을 이요한 자기콘덴서가 압도적으로 많고, 강유전체 본래의 성질을 이용한 것은 적다.The following is semiconducting ceramics. Currently, industrially, BaTiO 3 has an overwhelming number of magnetic capacitors with high dielectric constants, and few uses ferroelectric intrinsic properties.

이온성 결정으로 생각되는 BaTiO3는 그 비저항(比抵抗)이 보통 1010Ωcm이상되는 좋은 절연체이지만, 순도가 좋은 BaTiO3에 희토류 Bi, Sb 등을 미량 첨가하여 소결체를 만들면 상온 비저항(比抵抗)이 101~103Ωcm까지 크게 저하하여 세라믹 반도체가 된다. 이 세라믹스 반도체는 강유전 상(相)에서 상유전 상(相)으로 상(相)전이가 일어나는 온도, 즉 큐리온도 부근에서 비저항(比抵抗)이 103~105배 가량 급격히 증가하는 이상(異常) 현상이 나타나고, 이를 정(正)온도계수(Positive Temperature Coefficient, PTC)라 부른다.BaTiO 3 that are considered to be of ionic crystals is that the resistivity (比抵抗) Normal 10 10 Ωcm good insulator, but the room temperature resistivity (比抵抗) with a purity of addition of rare earth Bi, Sb and so on in good BaTiO 3 traces of creating a sintered body which is at least This greatly decreases to 10 1 to 10 3 Ωcm to form a ceramic semiconductor. This ceramic semiconductor has an abnormal increase in the specific resistance of 10 3 to 10 5 times in the vicinity of the Curie temperature at which the phase transition occurs from the ferroelectric phase to the phase dielectric phase. ) Phenomenon, which is called positive temperature coefficient (PTC).

발열 소자용으로는 소형난방기(온풍기), 소형가열기구, 정온(定溫)가열기 등 광범위한 시장이 있다.There are a wide range of markets for heating elements, such as small heaters (heaters), small heaters, and constant temperature heaters.

온풍 발열소자용 PTC에 대한 전형적인 형상은 하모니카 방식, 허니콤 방식, 핀 방식 등이 있다.Typical shapes for the PTC for warm air heating elements include harmonica, honeycomb, and fin.

그러나 반도성 세라믹스는 취성(brittleness)이 있고, 일정한 형상으로만 성형할 수 있어, 유연한 면상 발열소자와 내굴곡성 있는 그물망 발열소자로 응용할 수 없는 문제점들이 있다. However, semiconducting ceramics have brittleness and can only be molded into a certain shape, and thus there is a problem in that they cannot be applied to flexible planar heating elements and flexible mesh heating elements.

There is a problem that can not provide a safe heating element because there is no constant temperature function that increases rapidly by about 10 3 ~ 10 5 times.
