Description
본 발명은, 냉장고용 도어강판의 제조방법에 관한 것으로, 더욱 상세하게는 도어강판의 긁힘을 방지할 수 있는 냉장고용 도어강판의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a door steel sheet for a refrigerator, and more particularly, to a method for manufacturing a door steel sheet for a refrigerator that can prevent scratching of the door steel sheet.
이하에서는 도 1 및 도 2를 참조하면서, 종래의 냉장고용 도어강판 및 도어의 제조방법에 대해서 설명한다.Hereinafter, with reference to FIGS. 1 and 2, a conventional method for manufacturing a door steel plate and a door for a refrigerator will be described.
도 1에 도시된 바와 같이, 종래의 냉장고용 도어강판은, 일명 VCM(vynil coated metal)으로 제작되었다. 즉, 철판(2)에 강화비닐(8)을 접착제(4)로 부착하여 제조하였다.As shown in Figure 1, the conventional door steel sheet for a refrigerator, aka VCM (vynil coated metal) was made. That is, it was manufactured by attaching the reinforced vinyl (8) to the iron plate (2) with an adhesive (4).
상기 강화비닐(8)은, 상기 철판(2)을 보호하는 역할을 한다. 또한, 상기 강화비닐(8)에는 도어의 미감을 부여하기 위해 안료(6)가 도색되어 있다.The reinforced vinyl 8 serves to protect the iron plate 2. In addition, the reinforced vinyl 8 is painted with a pigment 6 to give the door aesthetics.
한편, 상기와 같이 제작된 도어강판(1)은 원하는 형상으로 절곡된다. 그리고, 상기 도어강판(1) 내측(도 2에서는 하측)에는 일정한 형상으로 가공된 도어 라이너(9)가 결합되게 된다(도 2 참조).On the other hand, the door steel sheet 1 produced as described above is bent into a desired shape. In addition, the door liner 9 processed in a predetermined shape is coupled to the inside of the door steel plate 1 (lower side in FIG. 2) (see FIG. 2).
그리고, 상기 도어강판(1)과 상기 도어 라이너(9)로 이루어진 공간에는 발포재가 포함된 단열재(B)를 주입하게 되면, 도어가 완성되게 된다.In addition, when the heat insulating material B including the foam material is injected into the space formed by the door steel plate 1 and the door liner 9, the door is completed.
그런데, 상기와 같이 도어강판 제조방법에 의해 도어강판을 제조하면, 상기 도어강판 외부의 강화비닐은 강도가 낮기 때문에, 도어강판 및 도어 제작과정에서 도어강판 표면에 스크라치, 즉 긁힘 등으로 인한 불량이 많이 발생하여 폐기되는 문제점이 있었다.However, when the door steel sheet is manufactured by the door steel sheet manufacturing method as described above, since the reinforced vinyl outside the door steel sheet has low strength, defects due to scratches, that is, scratches, etc. on the door steel sheet surface during the door steel sheet and the door manufacturing process are prevented. There was a problem that occurred a lot occurs.
본 발명은 상기 문제점을 해결하기 위해서 안출된 것으로서, 본 발명의 목적은 도어강판의 긁힘을 방지할 수 있는 냉장고용 도어강판 제조방법을 제공하는 것이다.The present invention has been made to solve the above problems, an object of the present invention is to provide a door steel sheet manufacturing method for a refrigerator that can prevent the scratch of the door steel sheet.
또한, 본 발명의 다른 목적은, 도어의 변색을 방지하고 별도의 광택제를 사용하지 않아도 고광택을 유지할 수 있는 냉장고용 도어강판 구조를 제공하는 것이다.In addition, another object of the present invention is to provide a door steel plate structure for a refrigerator which can prevent discoloration of the door and maintain high gloss without using a separate varnish.

본 발명은 상기 문제점을 해결하기 위해서 안출된 것으로서, 본 발명에 의한 냉장고용 도어강판 제조방법은, 철판을 냉장고용 도어의 형상으로 절곡하는 단계와; 상기 철판에 안료를 입히고 유약을 바른 후 일정온도에서 가열하는 단계를 포함하여 구성되는 것을 특징으로 한다.The present invention has been made to solve the above problems, the method for manufacturing a door steel plate for a refrigerator according to the present invention comprises the steps of bending the iron plate in the shape of the door for the refrigerator; After coating the iron plate with a pigment and glaze is characterized in that it comprises a step of heating at a certain temperature.
상기한 구성에 의하면, 철판을 절곡한 후 상기 철판의 표면에 유약을 바르고 가열하여 마무리 하므로, 냉장고 도어강판 표면의 긁힘을 방지할 수 있는 이점이 있다. 또한, 도어강판의 표면을 유약으로 처리하므로 장기간 사용해도 냉장고 도어강판이 변색되는 것을 방지할 수 있고, 별도의 광택제를 사용하지 않아도 고광택을 유지할 수 있는 이점이 있다.According to the above configuration, after the iron plate is bent and glazed on the surface of the iron plate and finished by heating, there is an advantage that can prevent scratching the surface of the refrigerator door steel sheet. In addition, since the surface of the door steel sheet is treated with a glaze, the refrigerator door steel sheet can be prevented from discoloring even if used for a long time, and there is an advantage of maintaining high gloss without using a separate varnish.
이하, 첨부된 도면을 참조하면서, 본 발명에 의한 바람직한 실시예에 대해서 설명한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
먼저, 도 3을 참조하면서 본 발명에 의한 냉장고용 도어강판 제조방법에 대해서 설명한다.First, the manufacturing method of the door steel plate for a refrigerator by this invention is demonstrated, referring FIG.
본 발명에 의한 냉장고용 도어강판 제조방법은, 두 단계로 구성된다.The method for manufacturing a door steel sheet for a refrigerator according to the present invention includes two steps.
첫번째 단계는, 도어강판(22)을 구성하는 철판(12)을 절곡하여 도어형상으로 제작하는 단계이다.The first step is to bend the iron plate 12 constituting the door steel plate 22 to produce a door shape.
두번째 단계는, 상기 방법으로 제작된 철판(12)에 안료(14)를 입히고 유약(16)을 바른 후, 일정온도에서 가열하는 단계이다. 이때, 가열온도는 1500℃ 이상으로 한다.The second step is to apply a pigment 14 to the iron plate 12 produced by the above method and to apply a glaze 16, and then to heat at a constant temperature. At this time, heating temperature shall be 1500 degreeC or more.
상기와 같이 본 발명에 의한 도어강판 제조방법은, 철판(12)을 냉장고용 도어 형상으로 절곡한 후 표면처리를 하기 때문에, 철판(12)의 절곡 과정에서 가해질 수 있는 도어강판의 표면 긁힘 등을 방지할 수 있다.As described above, in the method of manufacturing a door steel sheet according to the present invention, since the iron plate 12 is bent into a shape of a door for a refrigerator, the surface treatment is performed, and thus the surface scratches and the like of the door steel sheet which may be applied in the bending process of the iron plate 12 may be applied. You can prevent it.
상기와 같은 제조방법에 의해 제조된 본 발명에 의한 도어강판(22)은, 도어 형상의 철판(12)과, 상기 철판(12) 상면에 입혀진 안료(14)와, 상기 안료(16) 상면에 발라지고 가열된 유약(16)으로 구성된다.The door steel sheet 22 according to the present invention manufactured by the above-described manufacturing method includes a door-shaped iron plate 12, a pigment 14 coated on the upper surface of the iron plate 12, and an upper surface of the pigment 16. It consists of a glazed and heated glaze 16.
상기한 구성의 냉장고용 도어강판(22)은, 안료(14) 상면에 유약(16)을 바르고 고온에서 가열하였기 때문에, 철판(12)와 완전히 일체화되어 있어 분리되지 않으며, 접착제를 사용할 필요가 없다. 또, 고온에서 가열된 유약(16)은 강도가 강하기 때문에, 냉장고 도어강판 및 도어 제작시 충격에 의해 긁힘이 발생되지 않는다.Since the door steel sheet 22 for refrigerators having the above-described structure is coated with glaze 16 on the upper surface of the pigment 14 and heated at a high temperature, the door steel sheet 22 for refrigerator is completely integrated with the iron plate 12 and is not separated, and there is no need to use an adhesive. . In addition, since the glaze 16 heated at a high temperature has a strong strength, scratches are not generated due to an impact when the refrigerator door steel sheet and the door are manufactured.
그리고, 상기 유약(16)에 의해 상기 철판(12) 및 안료(14)가 공기와 접하는 경우가 드물기 때문에, 도어강판(22)이 변색되는 것을 방지할 수 있다.In addition, since the iron plate 12 and the pigment 14 rarely come into contact with the air by the glaze 16, it is possible to prevent the door steel plate 22 from being discolored.
또한, 상기 유약(16)은 고광택이므로,별도의 광택제를 사용하지 않아도 고광택을 유지한 수 있는 이점이 있다.In addition, the glaze 16 has a high gloss, there is an advantage that can maintain a high gloss without using a separate varnish.
도 4를 참조하면 알 수 있듯이, 상술한 바와 같이 제작된 도어강판(22)과 일정형상으로 가공된 도어라이너(24)가 결합되고, 상기 도어강판(22)과 도어라이너(24)로 이루어진 공간에 발포재가 포함된 단열재가 충진되면, 냉장고용 도어가 완성된다.As can be seen with reference to Figure 4, the door steel plate 22 manufactured as described above and the door liner 24 processed in a predetermined shape is coupled, the space consisting of the door steel plate 22 and the door liner 24 When the insulating material containing the foam is filled in, the door for the refrigerator is completed.
상술한 바와 같이, 본 발명에 의한 냉장고용 도어강판은 철판을 가공한 후 유약을 바르고 고온에서 가열하는 방식으로 표면처리하였기 때문에, 도어강판의 표면이 긁히는 것을 최대한 방지할 수 있는 효과는 도모할 수 있다.As described above, since the door steel sheet for the refrigerator according to the present invention is surface-treated in a manner of applying a glaze and heating at a high temperature after processing the steel sheet, the effect that can prevent the surface of the door steel sheet from scratching as much as possible can be achieved. have.
본 발명의 또 다른 효과는, 장기간 사용해도 도어강판의 표면이 변색되거나, 별도의 광택제를 사용하지 않아도 고광택을 유지할 수 있다는 점이다.Another effect of the present invention is that even when used for a long time, the surface of the door steel sheet can be discolored, or high gloss can be maintained without using a separate varnish.
