아래에서는 각 구성요소에 대하여 상세히 설명한다.Hereinafter, each component will be described in detail.
본 발명에 따른 난방용 발열체는 기본적으로 나일론, 테프론, 복합수지 및 카본블랙의 조합으로 이루어지는데, 나일론, 테프론 및 복합수지는 먼저 혼합되어 복합물을 형성하고, 이후에 카본블랙과 혼합된다.Heating element according to the present invention basically consists of a combination of nylon, Teflon, composite resin and carbon black, nylon, Teflon and composite resin is first mixed to form a composite, and then mixed with carbon black.
나일론(Nylon)은 폴리아미드(Polyamid)계의 합성섬유의 일반명으로서, 융점이 200℃ 정도에서 형성된다. 본 발명에서 사용되는 나일론의 종류에는 한정이 없으며, 6-나일론, 6,6-나일론, 6,10-나일론, 7-나일론, 9-나일론, 11-나일론 등이 사용될 수 있다. 본 발명에 따른 난방용 발열체의 나일론은 복합물의 전체 중량 대비 50 내지 75%를 차지한다.Nylon is a common name for polyamide-based synthetic fibers and has a melting point of about 200 ° C. The type of nylon used in the present invention is not limited, and 6-nylon, 6,6-nylon, 6,10-nylon, 7-nylon, 9-nylon, 11-nylon and the like can be used. Nylon of the heating element according to the invention occupies 50 to 75% of the total weight of the composite.
테프론(Teflon)은 폴리불화에틸렌계 합성섬유의 상품명으로서, 융점이 280℃ 정도에서 형성된다. 본 발명에 따른 난방용 발열체의 테프론은 복합물의 전체 중량 대비 10 내지 20%를 차지한다.Teflon is a trade name of polyfluoroethylene-based synthetic fibers and has a melting point of about 280 ° C. Teflon of the heating element for heating according to the present invention accounts for 10 to 20% of the total weight of the composite.
복합수지는 여러 가지의 합성수지들을 혼합하여 제조한 것으로서, ABS(Acrylonitrile Butadiene Styrene), PVC(Polyvinyl Chloride), PC(PolyCarbonate), PS(Polystyrene), PP(PolyPropylene) 등의 조합으로 이루어질 수 있다. 본 발명에 따른 난방용 발열체의 복합수지는 복합물의 전체 중량 대비 15 내지 30%를 차지한다.Composite resin is prepared by mixing a variety of synthetic resins, it may be made of a combination of ABS (Acrylonitrile Butadiene Styrene), PVC (Polyvinyl Chloride), PC (PolyCarbonate), PS (Polystyrene), PP (PolyPropylene). The composite resin of the heating element for heating according to the present invention accounts for 15 to 30% of the total weight of the composite.
이와 같이 본 발명에 따른 난방용 발열체의 복합물은 후술할 카본블랙의 함량에 따라 결정되는데, 전체 중량 대비 70 내지 85%를 차지한다.Thus, the composite of the heating element according to the present invention is determined according to the content of the carbon black to be described later, occupies 70 to 85% of the total weight.
카본블랙 1 내지 500㎛ 크기의 탄소로서, 함유량에 따라 발열되는 온도의 크기가 결정된다. 본 발명에 따른 카본블랙의 함량은 전체 중량 대비 15 내지 30%를 차지한다. 만약 카본블랙의 함량이 30%를 초과할 경우 발열체의 온도가 높아지고, 축열로 인해 온도가 더욱 높아져 발열체가 녹는 문제가 발생한다. 15% 미만의 경우에는 발열 온도가 낮아 열효율이 떨어진다.Carbon Black As carbon having a size of 1 to 500 µm, the size of the temperature generated by the content is determined. The content of carbon black according to the present invention accounts for 15 to 30% of the total weight. If the carbon black content exceeds 30%, the temperature of the heating element becomes high, and the temperature increases due to heat storage, thereby causing a problem of melting the heating element. If less than 15%, the heat generation temperature is low, the thermal efficiency is lowered.
아래에서는 본 발명에 따른 난방용 발열체의 제조방법을 설명한다.Hereinafter, a manufacturing method of a heating element for heating according to the present invention will be described.

First, the composite, each material in the range of 50 to 75% by weight of nylon, 10 to 20% by weight of teflon and 15 to 30% by weight of the composite resin is placed in a mixer, melted and mixed at a temperature of 280 to 300 ℃, and solidified at room temperature.
그리고 복합물 70 내지 85 중량%와 카본블랙 15 내지 30 중량%를 믹서에 넣은 뒤 250 내지 260℃의 온도에서 용융시켜 혼합한 다음 압출하여 성형한다. 이때 성형되는 압출물의 형태는 단면이 원형 또는 다각형으로 이루어질 수 있으며, 그 형상에 한정되지 않는다.Then, 70 to 85% by weight of the composite and 15 to 30% by weight of carbon black are placed in a mixer, melted and mixed at a temperature of 250 to 260 ° C, and extruded to form. In this case, the shape of the extrudate to be formed may have a circular or polygonal cross section, and is not limited thereto.
그리고 실제 사용 시에는 압출물을 커버할 수 있도록 외피를 형성시키는 것이 바람직한데, 이때 사용되는 외피에는 한정이 없으나 일반적인 합성수지를 사용할 경우에는 발열체의 온도로 인해 녹을 수 있으니 융점이 적어도 120℃ 이상의 복합수지를 이용하는 것이 바람직하다.And in actual use, it is desirable to form an outer sheath to cover the extrudate, but there is no limitation to the outer sheath used, but when using general synthetic resin, it may melt due to the temperature of the heating element, so that the melting point is at least 120 ° C. It is preferable to use.

시험예 Test Example
위에서 제조된 실시예 1 내지 4의 발열체의 양끝에 각각 +, - 전극을 연결하고 220V의 전압으로 전류를 흘려준 뒤 24시간 후에 각 실시예에 따른 발열체의 온도를 각각 측정하였으며, 실시예 1의 결과는 도 1에 도시되어 있고, 실시예 2의 결과는 도 2에 도시되어 있으며, 실시예 3의 결과는 도 3에 도시되어 있고, 실시예 4의 결과는 도 4에 도시되어 있다.After connecting the + and-electrodes to both ends of the heating element of Examples 1 to 4, respectively, and flowing a current at a voltage of 220 V, the temperature of the heating element according to each example was measured after 24 hours, respectively. The results are shown in FIG. 1, the results of Example 2 are shown in FIG. 2, the results of Example 3 are shown in FIG. 3, and the results of Example 4 are shown in FIG. 4.
도 1 및 2에 도시된 바와 같이 카본블랙이 30% 함유된 실시예 1 및 2는 발열체의 온도가 90℃까지 상승하였으며, 발열체가 녹아내리는 현상은 발견되지 않았다. 그리고 도 3 및 도 4에 도시된 바와 같이 카본블랙이 15% 함유된 실시예 3 및 4는 발열체의 온도가 60℃까지 상승하였으며, 발열체가 녹아내리는 현상은 발견되지 않았다.As shown in FIGS. 1 and 2, in Examples 1 and 2 containing 30% of carbon black, the temperature of the heating element was increased to 90 ° C., and the phenomenon in which the heating element melted was not found. In addition, as shown in FIGS. 3 and 4, in Examples 3 and 4 containing 15% of carbon black, the temperature of the heating element was increased to 60 ° C., and the phenomenon in which the heating element melted was not found.
이와 같이 본 발명은 높은 온도에서도 녹지 않고 높은 내구성을 유지하면서 사용할 수 있어 비닐하우스, 단독 주택과 같이 외부 환경에 노출이 많아 열손실률이 높은 장소에 사용되더라도 높은 온도를 유지할 수 있는 장점이 있다. 즉, 일반적으로 발열체는 외부에 노출되지 않고 시멘트 등에 매립되어 설치되므로 최대 온도가 낮을 경우 전달되는 온도가 낮은 문제점이 있으나, 본 발명에 따른 난방용 발열체는 위에서 살펴본 바와 같이 100℃에 근접한 온도까지 상승할 수 있어 비닐하우스나 단독 주택에서도 상당한 수준의 온도를 유지할 수 있다.As such, the present invention can be used while maintaining high durability without melting even at a high temperature, so there is an advantage of maintaining a high temperature even when used in a place with a high heat loss rate due to high exposure to the external environment such as a vinyl house or a single house. That is, in general, the heating element is embedded in cement, etc., without being exposed to the outside, so the maximum temperature is low, but the temperature delivered is low. However, the heating element according to the present invention may rise to a temperature close to 100 ° C. as described above. It can be maintained at a considerable temperature even in a plastic house or a detached house.
또한 본 발명은 복합수지와 카본블랙의 배합비율로 인해 PTC(Positive temperature coefficient) 효과를 높임으로써 일정 수준의 온도에 도달할 경우 높은 저항으로 인해 전도성이 낮아져 과열되는 것을 방지할 수 있어 안전하다.In addition, the present invention is safe by increasing the PTC (Positive temperature coefficient) effect due to the compounding ratio of the composite resin and carbon black to prevent overheating due to high resistance when reaching a certain level of temperature.
