By joining (20), it is possible to print the image 12 on the plated steel plate 10 by an inexpensive gravure printing method, and additional processes are not required, and printing errors occur because the plated steel plate is flat without rustling. Can be prevented.

또한, 발열 및 방사능 차폐 기능을 가진 필름(20)을 제조할 때, 베이스 필름(21)과 커버 필름(25)을 같은 폴리에틸렌 소재로 사용하여, 사용과정에서 열에 의해 베이스 필름(21)과 커버 필름(25)의 접합이 떨어지거나 뒤틀리는 현상을 방지할 수 있다.In addition, when manufacturing the film 20 having heat and radiation shielding function, the base film 21 and the cover film 25 are used as the same polyethylene material, and the base film 21 and the cover film are heated during the use process. (25) It is possible to prevent the phenomenon of falling off or distorting the joint.

더 나아가, 본 발명에 따른 발열도금강판 제조방법은 발열 및 방사능 차폐 기능을 가진 필름(20)에 열반사 필름(30)을 접합함으로써, 건물 내장재 패널의 두께를 얇게 형성할 수 있는 장점이 있다.Furthermore, the method of manufacturing a heat-resistant plated steel sheet according to the present invention has the advantage of being able to form a thin thickness of the building interior panel by bonding the heat-reflecting film 30 to the film 20 having heat and radiation shielding function.

상기와 같은 제조방법으로 제조된 본 발명에 따른 발열도금강판은 도금강판(10)의 정면에 이미지가 인쇄되고, 도금강판(10)이 특성상 정온 발열체(22)에서 발산하는 열을 외부로 방사하는 방열판 기능하고, 열반사 필름(30)에 의해 온전히 도금강판(10) 앞으로 방열됨으로써, 다른 건축 패널 보다 열을 더 효율적으로 잘 외부로 방사할 수 있어, 실내 보조 난방으로 사용되거나, 난방이 이루어지지 않고 있는 상가 화장실이나 외부 화장실의 내벽에 부착되는 패널 등을 사용될 수 있다.In the heating plated steel sheet according to the present invention manufactured by the above manufacturing method, an image is printed on the front of the plated steel plate 10, and the plated steel plate 10 radiates the heat radiated from the constant temperature heating element 22 to the outside due to its characteristics. It functions as a heat sink and is completely radiated in front of the plated steel plate 10 by the heat reflecting film 30, so that heat can be radiated to the outside more efficiently than other building panels, so it is used as an indoor auxiliary heating or heating is not performed. A panel attached to the inner wall of a commercial toilet or an external toilet can be used.

이와같이 난방이 이루어지지 않고 있는 상가 화장실이나 외부 화장실의 내벽 패널 등으로 사용될 경우, 상가 화장실이나 외부 화장실에 동파 방지를 위해 별도로 히터 등을 설치할 필요가 없게 된다. When used as an inner wall panel of a commercial toilet or external toilet that is not heated as described above, it is not necessary to separately install a heater or the like in the commercial toilet or external toilet to prevent freezing.

또한, 본 발명에 따른 발열도금강판은 비스무스 분말을 포함하는 용액이 코팅되어 있어, 건물의 벽에서 방출되는 방사능(특히, 라돈)을 차단하게 되어, 안전한 실내 환경을 구현할 수 있으며, 방사능에 의한 인체 피해를 최소화할 수 있게 된다.In addition, since the heating plated steel sheet according to the present invention is coated with a solution containing bismuth powder, it blocks radioactivity (especially radon) emitted from the walls of the building, thereby realizing a safe indoor environment, and Damage can be minimized.
