The following description is provided to assist the understanding and implementation of the present invention, but the present invention is not limited thereto. It will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention as set forth in the following claims.

먼저, 도 1은 본 발명의 무금속 탄소나노튜브 발열체를 사용하는 전기매트(100)의 내부도를 나타낸 것으로서, 부직포 등의 원단(10) 상에 다중벽 탄소나노튜브(MWCNT), PLA, PBT 및 PBAT로 만들어진 탄소나노튜브 발열체(20)를 병렬로 배치한 다음, 각 상기 발열체(20)를 전선(70)으로 연결한다.1 is an internal view of an electric mattress 100 using a metal-free carbon nanotube heating element of the present invention. The metal martensitic carbon nanotube (MWCNT), PLA, PBT And the carbon nanotube heating elements 20 made of PBAT are arranged in parallel, and each of the heating elements 20 is connected to the electric wire 70.

상기에서, 병렬로 연결된 발열체(20)와 전선(70)과의 연결은 도 2에 나타낸 바와 같이 인서트사출접착(80)한다.In the above, the connection between the heating elements 20 connected in parallel and the electric wire 70 is insert injection bonding 80 as shown in FIG.

또한, 상기 원단(10) 상에 병렬로 배치된 발열체(20) 사이에는 2개 이상의 온도센서(40)를 부착시켜 사용 시 매트(100)의 온도를 감지하게 하고, 하나 이상의 온도퓨즈(30)를 부착시켜 과부하 시의 전류를 차단하게 한다.Two or more temperature sensors 40 may be attached between the heating elements 20 arranged in parallel on the fabric 10 so that the temperature of the mat 100 is sensed during use and at least one temperature fuse 30, So that the current at the time of overloading is cut off.

상기에서 발열체(20)를 연결하는 전선(70) 및 온도센서(40)와 온도퓨즈(30)를 연결하는 전선(70)은 통상의 온도조절기(50)와 연결되고, 상기 온도조절기(50)는 외부의 어댑터(60)를 통하여 에너지원(도시되지 않음)과 연결되게 된다.The electric wire 70 connecting the heating element 20 and the electric wire 70 connecting the temperature sensor 40 and the thermal fuse 30 are connected to the conventional temperature controller 50, Is connected to an energy source (not shown) through an external adapter 60.

상기와 같이 원단(10)에 발열체(20), 온도퓨즈(30), 온도센서(40) 등을 전선(70)으로 연결하여 마감하면 그 상면을 또 다른 원단으로 감싼 다음 상, 하면에 표면원단을 놓고 재봉 등의 방법으로 마감하면 본 발명의 전기매트(100)가 완성된다.When the heating element 20, the thermal fuse 30, the temperature sensor 40 and the like are connected to the fabric 10 by the electric wire 70 as described above, the upper surface of the fabric is wrapped with another fabric, The electric mat 100 of the present invention is completed.

When the temperature is overheated, the temperature fuse 30 operates to change the current A 220V alternating current drawn from a household outlet is converted from an adapter 60 to a direct current, and the electric current is supplied to the electric wire 70 through the temperature regulator 50, (20), there is no danger of electric shock and the thermal efficiency is increased.

이하에서는 본 발명에서 사용하는 다중벽 탄소나노튜브를 사용하는 탄소나노튜브 발열체(20)에 대하여 설명한다.Hereinafter, a carbon nanotube heating element 20 using the multi-walled carbon nanotubes used in the present invention will be described.

상기 본 발명에서 사용하는 탄소나노튜브 발열체(20)는 다중벽 탄소나노튜브(Multi-Walled CNT, MWCNT)와 PLA(Poly Lactic Acid), PBT(Polybutylene Terephthalate) 및 PBAT(Polybutylene Adipate-co-terephthalate)를 몰딩 컴파운드로 만든 후 이를 압출하여 약 3.5~4.0mm 두께의 굵기로 발열선이 되게 만든 것이다.The carbon nanotube heating element 20 used in the present invention may be a multi-walled carbon nanotube (MWCNT), a poly lactic acid (PLA), a polybutylene terephthalate (PBT), a polybutylene adipate-co-terephthalate (PBAT) Made into a molding compound, and extruded to make a heating wire with a thickness of about 3.5 to 4.0 mm.

바람직하게는 MWCNT 12~15wt%, PLA 10~14wt%, PBT 61~73wt%, 그리고 PBAT 5~10wt%를 몰딩 컴파운드로 만든 후 이를 압출하여 만든다.Preferably, 12 to 15 wt% of MWCNT, 10 to 14 wt% of PLA, 61 to 73 wt% of PBT, and 5 to 10 wt% of PBAT are molded into a molding compound and then extruded.

상기와 같이 만들어진 발열선이 두께 3.75mm, 길이 1000mm일 때 발열선 1개 당 DC 12V를 넣으면 0.24A가 흐르게 되었고, 발열선 자체의 온도는 45℃가 되었다.When the heating wire made as described above was 3.75 mm in thickness and 1000 mm in length, 0.24 A was flowed when DC 12 V was applied per heating wire, and the temperature of the heating wire itself was 45 ° C.

상기와 같은 조건으로 도 1과 같이 구성하고 단열원단(10)을 상, 하로 덮었을 때는 온실효과로 인하여 55~60℃가 되었다.1 under the same conditions as described above. When the insulating fabric 10 was covered with the top and the bottom, the temperature was 55 to 60 deg. C due to the greenhouse effect.

상기와 같은 탄소나노튜브로 만들어지는 발열체(20)인 발열선은 열용량이 작기 때문에 열을 품고 있지 않고 외부로 90% 이상을 방출하는 특성을 갖고 있어서, 금속발열체에 비해 온화하고 따뜻한 특성을 갖고 있고 열을 방출하는 양이 많기 때문에 결과적으로 매트 내부로 골고루 열을 전달시키게 되는 장점을 가지게 되어, 본 발명에서 사용하는 것이다.Since the heating wire 20, which is a heating element 20 made of carbon nanotubes, has a characteristic of emitting 90% or more of heat to the outside because of its small heat capacity, it has a milder and warmer characteristic than a metal heating element, So that the heat is uniformly transferred to the inside of the mat, which is used in the present invention.

상기 표 7에서도 확인할 수 있듯이 본 발명은 음이온을 방출하는 발열체를 사용함으로서 인체에도 유익한 방석을 제공할 수 있게 된다.As can be seen in Table 7, the present invention can provide a cushion useful for the human body by using a heating element that emits negative ions.

또한 본 발명에서 사용하는 발열체인 발열사는 온도계수가 PTC(Positive Temperature Coefficient)를 갖고 있어서, 발열사 자체가 온도 자기제어기능이 있고, 저온(0~10℃) 시 발열 특성이 상승되며, 과열방지 및 절전 기능이 있는데 이는 온도가 상승하면 발열체가 팽창하고 나노탄소튜브의 접점점이 이격되어 전기전도성이 다운/업 되어 일정한 온도를 유지할 수 있으며, 과전압이나 과전류가 흐를 경우 자체 퓨즈기능을 갖고 있어서, 200℃ 이상 시에는 자체 단선되어 본 발명에서 유용하게 사용할 수 있다. In addition, the heating yarn, which is a heating element used in the present invention, has a temperature coefficient of PTC (Positive Temperature Coefficient), so that the heating yarn itself has a temperature self-controlling function and the heating characteristic is raised at low temperature (0 to 10 ° C) This is because when the temperature rises, the heating element expands, the contact points of the nano carbon tubes are separated, the electric conductivity can be down / up to maintain a constant temperature, and when the overvoltage or the overcurrent flows, It can be used by itself in the present invention.
