본 발명은 천정매립형 공기조화기등에 매우 적합한 단열강판과 이것을 사용한 공기조화기용 부재의 제조방법에 관한 것이다.The present invention relates to a heat-insulating steel sheet which is very suitable for a ceiling-embedded air conditioner and the like and a manufacturing method of an air conditioner member using the same.

일반적으로 천정매립형 공기조화기는 제7도에 나타낸 것처럼, 천정판(1)의 뒷면쪽에 공기조화기본체(2)를 설치하는 한편, 천정판(1)이 내면쪽에는 화장패널(3)를 설치하고 도면에서 대실선으로 나타낸 것처럼 실내공기를 공기조화기본체(2)내로 흡입하고, 이것을 열교환하여 냉풍 또는 난풍을 실내로 토출하여 냉난방하도록 되어 있다. 그리고 공기조화기본체(2) 및 화장패널(3)은 냉방운전시의 이슬부착방지와 난방운전시의 열손실 저감을 목적으로 여러곳에 단열재를 설치하고 있다.Generally, the ceiling-embedded air conditioner installs the air conditioner main body 2 on the rear side of the ceiling plate 1, as shown in FIG. 7, while the ceiling panel 1 installs the makeup panel 3 on the inner surface side. As shown by the solid line in the drawing, the indoor air is sucked into the air conditioner main body 2, and heat-exchanged to discharge cold air or warm air into the room for cooling and heating. In addition, the air conditioner main body 2 and the makeup panel 3 are provided with heat insulating materials in various places for the purpose of preventing dew adhesion during cooling operation and reducing heat loss during heating operation.

종래, 이 단열재는 일체성형의 LIM(Liquid Injection Mold)방식과 금형 성형으로 얻어지는 발포스티로폴등으로 되며, 제8도에 나타낸 것처럼 가령 공기조화기본체(2)의 케이싱(2a)의 내외면등에 이 단열재(4)를 붙이고 있다.Conventionally, the heat insulating material is formed of an integral molding liquid injection mold (LIM) method and a foamed styropol obtained by mold molding. As shown in FIG. 8, for example, the inner and outer surfaces of the casing 2a of the air-conditioning base body 2 are attached. The heat insulating material 4 is stuck.

그러나 이러한 종래의 LIM방식과 단열재의 점착방식에는 다음과 같은 과제가 있다.However, the conventional LIM method and the adhesive method of the heat insulating material has the following problems.

우선, LIM방식은 금형에 액상의 단열재를 흘려놓고 형성하는 것으로서 복잡한 형상인 것에는 응용할 수 없으며, 공기조화기본체(2)에 응용하는 경우에는 지그의 제작이 곤란할 뿐만 아니라, 주형재료의 누출을 방지할 수 없다. 또한, 발포스티로폴과 공기조화기본체(2)의 판금과 모울드 성형품등과는 열팽창계수가 다르므로 공기조화운전시에 판금과 발포스티로폴이 서로 스쳐서 마찰음이 발생할 뿐만 아니라, 결손이 발생되기 쉬워서 끼워맞춤부의 성형이 용이하지 않다. 또한 단열재(4)의 점착방식은 현재 가장 널리 보급되고 있는데, 제8도에 나타낸 것처럼 공기조화기본체(2)등의 성형품의 코너부와 단열재 상호의 맞춤면등에 틈새(g)가 형성되기 쉬워서 단열시일부족을 초래할 때가 많다.First of all, the LIM method is formed by pouring a liquid insulator into a mold and cannot be applied to a complicated shape. When the LIM method is applied to the air conditioner 2, it is difficult to manufacture a jig and prevent leakage of the molding material. Can't prevent it. In addition, since the coefficient of thermal expansion is different from the sheet metal of the foamed styropol and the air-conditioning base body (2), and the molded article, the sheet metal and the foamed styropole rub against each other during air conditioning operation, so that a friction noise is generated, and defects are likely to occur. Molding of parts is not easy. In addition, the adhesive method of the heat insulating material (4) is the most widely used now, as shown in Figure 8, the gap (g) is easily formed in the corner of the molded article, such as the air conditioning base body (2) and the mating surface of the heat insulating material, etc. Insulating seals are often lacking.

따라서, 이 단열시일부족 부분에 이슬부착과 단열재(4)의 접착제가 시간경과에 따라 약화되어 단열재(4)가 떨어지기 쉬울 뿐만 아니라, 점착위치의 어긋남에 의한 단열불량등의 과제가 있다.Therefore, the dew-adhesion and the adhesive of the heat insulating material 4 weaken with time, and the heat insulating material 4 is not easy to fall, but there exist problems, such as a poor heat insulation by the shift | adhesion of a sticking position.

그래서 본 발명은 이러한 사정을 고려하여 되어진 것으로서, 그 목적은 단열시일성의 향상등을 도모할 수 있는 단열강판과 이것을 사용하는 공기조화기용 부재의 제조방법을 제공하는데 있다.Accordingly, the present invention has been made in consideration of the above circumstances, and an object thereof is to provide a heat insulating steel sheet capable of improving insulation sealing properties and a method for manufacturing an air conditioner member using the same.

본 발명은 강판의 적어도 한면에 미발포된 발포제를 포함한 합성수지를 피착하고, 이후 성형가공하고 나서 상기 발포제를 발포시키도록 한 것으로서 다음과 같이 구성된다.The present invention is configured to deposit a synthetic resin including an unfoamed foaming agent on at least one side of a steel sheet, and then to foam the foaming agent after molding.

즉, 본원 발명은, 표면처리한 강판을 포함한 강판의 적어도 한쪽면에 미발포된 발포제를 포함한 합성수지를 피착시킨 뒤 이 강판을 성형가공하고, 그후 상기 발포제를 발포시켜서 단열층을 형성시키는 것을 특징으로 한다.That is, the present invention is characterized in that a synthetic resin containing an unfoamed foaming agent is deposited on at least one surface of a steel sheet including a surface-treated steel sheet, followed by molding the steel sheet, and then foaming the foaming agent to form a heat insulating layer. .

또한, 본원 발명은 강판의 한쪽면이 프레코트메탈강판의 피의장면인 것을 특징으로 한다.In addition, the present invention is characterized in that one side of the steel sheet is the surface of the precoated metal steel sheet.

또한, 본원 발명은 강판의 성형가공부재가 공기조화기용 부재인 것을 특징으로 한다.In addition, the present invention is characterized in that the molded processing member of the steel sheet is an air conditioner member.

그리고 본원 발명은 강판의 적어도 한쪽면에 미발포된 발포제를 포함한 합성수지를 피착한 후, 이 강판을 공기조화기용 부재에 성형가공하고, 그후 적어도 상기 한쪽면에 표면처리하고, 그후 이 표면처리를 베이킹하는 공정과 상기 발포제를 발포시키는 공정을 동시에 실행하는 것을 특징으로 한다.In the present invention, after depositing a synthetic resin containing an unfoamed foaming agent on at least one side of the steel sheet, the steel sheet is molded into an air conditioner member, and then surface treated on at least one side, and then the surface treatment is baked. And a step of foaming the foaming agent.

강판의 적어도 한쪽면에 그 성형가공전에 미발포된 발포제를 포함한 합성 수지를 피착하므로 이 합성수지를 강판의 적어도 한쪽면에 일정하게 피착시킬 수 있다. 따라서, 이 강판을 공기조화기용 부재등에 성형가공하고, 그후에 상기 발포제를 발포시켜서 단열층을 형성할 때는 성형가공품의 코너부등에도 단열층을 일정하게 형성할 수 있어서, 단열 시일성을 높일 수 있다.Since at least one side of the steel sheet is coated with a synthetic resin including an unfoamed foaming agent before its molding, the synthetic resin can be uniformly deposited on at least one side of the steel sheet. Therefore, when the steel sheet is molded into an air conditioner member or the like, and then the foaming agent is foamed to form a heat insulating layer, the heat insulating layer can be uniformly formed at the corners of the molded article, and the heat-sealing sealability can be improved.

상기 발명에서 의장처리 해야 할 강판의 한쪽면에는 미발포된 발포제를 포함한 합성수지가 피착되고, 강판의 가열에 의해 상기 발포제를 발포시키는 공정과 동시에 상기의 면에 가령 실크스크린 인쇄등의 처리를 한 것을 인쇄인화하는 공정과 동시에 실행할 수 있으므로 제조시간을 단축시킬 수 있을 뿐만 아니라, 양산성을 높일 수 있다. 또한, 발포제를 발포시키는 공정과 도장등의 도막을 정화시키는 강판의 표면처리를 베이킹하는 공정과 강판 및 발포제의 가열에 의해 동시에 실행할 수 있으므로, 제조시간의 단축과 합리화를 모두 도모할 수 있어서 양산성을 높일 수 있다.In the invention, a synthetic resin containing an unfoamed foaming agent is deposited on one side of the steel sheet to be treated, and at the same time as the foaming agent is foamed by heating the steel sheet, the surface is treated such as silk screen printing. Since it can be performed simultaneously with the printing process, not only can the manufacturing time be shortened, but also the mass productivity can be improved. In addition, since the process of foaming the foaming agent and the surface treatment of the steel sheet for purifying the coating film such as coating can be performed simultaneously with the heating of the steel sheet and the foaming agent, both production time can be shortened and rationalization can be achieved. Can increase.

이하, 본원 발명의 실시예를 도면에 의거하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described based on drawing.

제1a도~c도는 강판에, 미발포된 발포제를 포함한 합성수지를 피착하는 제1의 방법을 나타내는 도면으로서, 이 방법은 제1a도에 나타낸 것처럼 기초가 되는 합성수지로서 폴리염화 비닐수지(PVC)(11) 또는, 폴리에틸렌과 폴리스틸렌 등의 합성수지와 가소제(12), 안정제(13), 착색제(14)를 브렌더(15) 등으로 혼합시킨다.1a to c are diagrams showing a first method of depositing a synthetic resin containing an unfoamed foaming agent on a steel sheet, which is a polyvinyl chloride resin (PVC) as the synthetic resin as a base as shown in FIG. 11) Alternatively, synthetic resins such as polyethylene and polystyrene, the plasticizer 12, the stabilizer 13, and the colorant 14 are mixed with the blender 15 or the like.

그후, 이것을 믹서(16)로 혼합하여 겔 상태로하고 나서 발포제(17)를 첨가하여 믹싱로울(18)로 충분히 혼합한다.Thereafter, this is mixed with the mixer 16 to make a gel state, and then a blowing agent 17 is added to the mixing roll 18 to sufficiently mix.

이어서 이것을 제1b도에서 나타낸 칼렌로울(19)에 걸어서 미발포된 수지시트(20)를 제조한다.Subsequently, this is hanged on the Callen roll 19 shown in FIG. 1B, and the unfoamed resin sheet 20 is manufactured.

단, 상기 각 혼합공정에서의 온도는 발포제(17)의 화성화, 즉 발포제의 온도이하로 유지해야만 하며, 그 온도는 가령 130℃~150℃의 범위로 관리할 필요가 있다. 상기 발포제(17)로서는 150℃ 전후로 발포화되지 않는 것을 선정할 필요가 있으며, 분해온도가 높아서 가스발생량이 많은 것이 좋다. 가령 아조잘본 애시드등의 아조화합물과, 디 니트로소 펜타 메틸렌 테트라민등의 니트로소 화합물, 4,4′-옥시비스 벤젠설포닐세미카르 바지드 등이 있다.However, the temperature in each mixing process must be maintained at the temperature of the chemical conversion of the blowing agent 17, that is, below the temperature of the blowing agent, and the temperature must be managed in the range of 130 ° C to 150 ° C, for example. As the blowing agent 17, it is necessary to select one which is not foamed at around 150 ° C, and the gas generation amount is good because the decomposition temperature is high. For example, there are azo compounds such as azozabonbon acid, nitroso compounds such as dinitroso pentamethylene tetramine, and 4,4'-oxybis benzenesulfonyl semicarbamide.

그리고, 제1c도에 나타낸 것처럼 송출로울러(21)에 검겨 있는 긴띠형의 강판(22)의 일단부를 감는 로울(23)쪽으로 송출하고, 그 도중에서 강판(22)의 도면에서 상면상에 호퍼(24)에서 접착제(25)를 주입하여 전면적이고 일정하게 도포하고 있다. 이 접착제(25)로서는 내구성이 있는 아크릴계와 아크릴에스테르계, 또는 폴리염화비닐수지속의 가소제(12)의 이행현상이 있는 경우에는 니트릴부타디엔 고무(NBR)계를 사용하면 좋다. 또한, 이 호퍼(24)의 하류쪽 강판(22)의 상면상에는 추출로울(26)에서는 상기 미발포된 발포제를 포함한 수지시트(20)에서 추출되고, 강판(22)의 접착제(25)의 도포면에 두쌍의 압접로울(27),(28)에 의해 압착되고, 미발포 단열강판(22a),(28)에 의해 압착되고, 미발포 단열강판(22a)을 감는 로울(23)로 감는다.Then, as shown in FIG. 1C, one end of the long band-shaped steel sheet 22 wound on the feeding roller 21 is fed toward the roll 23, and in the meantime, a hopper (on the upper surface in the drawing of the steel sheet 22). In 24, the adhesive 25 is injected to apply the whole surface uniformly. As the adhesive 25, a nitrile butadiene rubber (NBR) system may be used when there is a transition phenomenon between the durable acrylic and acrylic ester plasticizers or the plasticizer 12 in the polyvinyl chloride resin. Moreover, on the upper surface of the downstream steel plate 22 of this hopper 24, the extraction roll 26 extracts from the resin sheet 20 containing the said unfoamed foaming agent, and the coated surface of the adhesive agent 25 of the steel plate 22 is carried out. It is crimped by two pairs of contact rollers 27 and 28, and it is crimped | bonded by the unfoamed heat insulation steel sheets 22a and 28, and is wound by the roll 23 which winds up the unfoamed heat insulation steel sheet 22a.

이후, 이 미발포 단열강판(22a)을 가령 제2도에 나타낸 것처럼 직사각형 판형으로 각각 절단한 뒤 구부림과 수축, 펀칭, 결합 등의 2차 가공을 하여 가령 공기조화기의 본체 케이싱등의 공기조화기용부재등으로 성형 가공한다.Subsequently, the unfoamed insulating steel sheets 22a are cut into rectangular plate shapes as shown in FIG. 2, and then subjected to secondary processing such as bending, shrinkage, punching, and bonding, for example, air conditioning such as a main body casing of an air conditioner. Molding is done with a member for use.

이 성형가공 완료후에 전자선 조사로와 가열로(29)내에 이 성형가공기를 넣어서 전자선 조사와 가열에 의해 수지시트(20)의 발포제(17)를 제2도에 나타낸 것처럼 발포시켜 발포단열층(30)을 강판(22)의 가령 외주면에 형성한다.After the molding process is completed, the molding machine is placed in the electron beam irradiation furnace and the heating furnace 29, and the foam insulation layer 30 is formed by foaming the foaming agent 17 of the resin sheet 20 as shown in FIG. 2 by electron beam irradiation and heating. It forms in the outer peripheral surface of the steel plate 22, for example.

따라서, 본 실시예에 따르면 강판(22)의 적어도 한쪽면에 수지시트(20)를 일정하게 접착하고 나서 발포제(17)를 발포화하므로 이 발포 단열층(30)을 강판(22)의 성형가공품 코너부 등에도 일정하게 형성할 수 있어서 단열시일성을 높일 수 있다.Therefore, according to the present embodiment, since the foaming agent 17 is foamed after uniformly adhering the resin sheet 20 to at least one side of the steel sheet 22, the foam insulation layer 30 is formed into a molded article corner of the steel sheet 22. Since it can form uniformly to a part etc., heat insulation sealing property can be improved.

제3a도, b도는 상기 강판(22)의 한쪽면에 발포제(17)를 포함한 수지(20)를 피착시키는 다른 방법을 나타내고 있다.3A and 3B show another method of depositing the resin 20 including the foaming agent 17 on one side of the steel sheet 22.

즉, 제3a도에 나타낸 것처럼 PVC(11), 가소제(12), 안정제(13), 착색제(14)를 브렌더(15)로 혼합한 후 믹서(16)로 미발포된 발포제(17)와 용제(31)를 혼합하고, 또한 혼합하여 수지용액(32)을 제조한다.That is, as shown in FIG. 3a, the PVC 11, the plasticizer 12, the stabilizer 13, and the colorant 14 are mixed with the blender 15, and then the foaming agent 17 unfoamed with the mixer 16 and The solvent 31 is mixed and mixed to prepare a resin solution 32.

이후, 제3b도에 나타낸 것처럼 송출로울(21)과 감는로울(23)사이에 길게 설치된 강판(22)의 가령 도면에서 상면상에 상기 수지용액(32)을 호퍼등에서 주입하여 전면적이고도 일정하게 도포하여 건조로(33)내를 통과시킴으로써 발포제(17)를 발포시키지 않도록 하여 수지시트(20)가 피착된 미발포 단열강판(22a)을 형성한다.Subsequently, as shown in FIG. 3B, the resin solution 32 is injected onto the upper surface of the steel sheet 22 provided between the feeding roll 21 and the winding roll 23 in a hopper or the like to be uniformly coated on the whole surface. By passing through the drying furnace 33 to prevent the foaming agent 17 from being foamed, the unfoamed insulating steel sheet 22a to which the resin sheet 20 is deposited is formed.

또한, 제4도는 재차 미발포 단열강판(22a)을 형성하는 다른 방법을 나타내고 있으며, 시트 압출기(34)에서 상기 수지시트(20)를 압출하여 가열연신장치(35)로 이 수지시트(20)를 늘리고, 송출로울(21)에서 송출되는 강판(22)의 도면에서 상면상에 이 수지시트(20)를 두상의 압접로울(22a)을 감는 로울(23)로 감도록 되어 있다. 이들 미발포 단열강판(22a)에는 전술한 제2도에 나타낸 공정에 의해 얻어진 미발포 수지(22)를 발포시킨 발포 단열층(30)의 단열층이 형성된다. 이처럼 발포 단열층(30)을 형성한 강판(22)은 제5도에 나타낸 공기조화기에 적용된다.4 shows another method of forming the unfoamed insulating steel sheet 22a again, and the resin sheet 20 is extruded from the sheet extruder 34 to the heating and stretching device 35. The resin sheet 20 is wound on the upper surface of the sheet of steel sheet 22 sent out from the delivery roll 21 by a roll 23 which winds the two-phase press contact rolls 22a. In these unfoamed heat insulating steel sheets 22a, a heat insulating layer of the foamed heat insulating layer 30 obtained by foaming the unfoamed resin 22 obtained by the process shown in FIG. 2 is formed. The steel sheet 22 in which the foamed heat insulating layer 30 is formed is applied to the air conditioner shown in FIG.

즉, 공기조화기(40)의 본체 케이싱(41)의 내외양면에, 제6도에 나타낸 것처럼 발포단열층(30)을 각각 형성하는 동시에, 간막이판(42), 송풍기(43)의 덕트와 팬케이싱, 드레이팬(44), 토출구(45)등 강판(22)에 의해 복잡한 형상으로 성형되는 공기조화기용부재에 대해서도 이들 강판(22)에는 미발포된 발포제(17)를 포함한 수지시트(20)를 전면적이고도 일정하게 피착하고 있다.That is, the foam insulation layer 30 is formed on the inner and outer surfaces of the main body casing 41 of the air conditioner 40, respectively, and at the same time, the ducts and fans of the partition plate 42 and the blower 43 are formed. Regarding the air conditioner member formed into a complicated shape by the steel sheets 22 such as the casing, the drain pan 44, and the discharge port 45, the steel sheets 22 include the resin sheet 20 including the unfoamed foam 17. Is being deposited all over the place.

따라서, 발포제(17)의 발포후에 형성되는 발포스티로폴의 발포단열층(30)은 성형품의 각부에 일정하고도 전면적으로 형성되므로, 종래예와 같이 성형품의 코너부에 단열층의 틈새(g)가 형성되거나, 단열층끼리의 맞춤면에 틈새등이 형성되는 것을 방지할 수 있어서 단열시일성을 높일 수 있다.Therefore, since the foam insulation layer 30 of the foamed styrofool formed after foaming of the foaming agent 17 is uniformly and entirely formed at each part of the molded article, the gap g of the heat insulation layer is formed at the corner of the molded article as in the conventional example. It is possible to prevent the formation of gaps and the like on the mating surfaces of the heat insulating layers, so that the heat insulating sealability can be improved.

그리고, 강판(22)의 한쪽면에 수지시트(20)가 피착되어 미발포 단열강판(22a)의 뒷면에, 도장등의 표면 처리를 한 경우에는 그 도장의 도포막 경화를 위한 베이킹 공정을 수지시트(20)에 포함되어 있는 상기 발포제(17)의 발포화 공정과 마찬가지로 강판(22)의 가열에 의해 실행하므로, 이 도포막 경화의 베이킹 공정과 발포제(17)의 발포화 공정을 가열함으로써 동시에 실행할 수 있어서, 제조시간의 단축을 도모할 수 있을 뿐만이 아니라, 제조단가 저감을 도모할 수 있다.When the resin sheet 20 is deposited on one side of the steel plate 22 and the surface of the unfoamed heat-insulated steel sheet 22a is subjected to surface treatment such as coating, the baking process for curing the coating film of the coating is performed. In the same manner as the foaming step of the foaming agent 17 contained in the sheet 20, it is performed by heating the steel sheet 22, so that this baking film curing step and the foaming step of the foaming agent 17 are simultaneously heated. In addition, the manufacturing time can be shortened, and the manufacturing cost can be reduced.

또한 프레코트메탈강판(도시하지 않음)에 의장이 처리된 상기 수지시트(20)를 피착하는 경우에 있어서도 강판(22a)에 공기조화기용 부재등으로 성형가공한 뒤, 이 프레코트메탈강판의 피의장면에 마크와 형명, 디자인등을 가령 실크스크린 인쇄등으로 인쇄하고, 그후 인쇄 인화공정을 상기 수지시트(20)에 포함되어 있는 상기 발포제(17)의 발포화공정과 동시에 가열함으로써 실행할 수 있으며, 이 경우에는 양 공정을 동시에 실행할 수 있으므로 제조시간의 단축을 도모할 수 있다.Also in the case of depositing the resin sheet 20 whose design is treated on a precoated metal steel sheet (not shown), the precoated metal steel sheet may be formed by molding the steel sheet 22a with a member for an air conditioner. It is possible to carry out printing by printing a mark, a model name, a design, etc. on the scene by, for example, silk screen printing, and then heating the print printing process simultaneously with the foaming process of the blowing agent 17 included in the resin sheet 20, In this case, since both processes can be performed simultaneously, manufacturing time can be shortened.

그리고, 본 실시예에 따르면 단열층을 형성하는 수지시트(20)는 강판(22)의 송출로울(21)과 감는로울(23)사이를 이동하는 강판(22)에 피착시켜 행하고, 이것에 의해 미발포단열강판(22a)이 형성되기 때문에 특별한 설비를 필요로 하지 않고 양산할 수 있다.In addition, according to the present embodiment, the resin sheet 20 forming the heat insulating layer is deposited on the steel sheet 22 moving between the feeding roll 21 and the winding roll 23 of the steel sheet 22. Since the foamed insulating steel sheet 22a is formed, it can be mass-produced without requiring special equipment.

또한, 수지시트(20)의 피막 두께 조절은 매우 용이하므로, 발포스티롤의 발포단열층(30)의 두께 조절도 매우 용이하게 실행할 수 있다.In addition, since the film thickness of the resin sheet 20 can be adjusted very easily, the thickness of the foam insulation layer 30 of foamed styrol can also be adjusted very easily.

또한, 수지시트(20)속의 발포제(17)의 혼입량을 적절히 조절함으로써 발포단열층(30)의 발포배율을 용이하게 조정할 수 있으며, 그 단열성능을 적절히 제어할 수 있다. 또한, 베이스레진을 여러 가지로 변형시킴으로써 재료특성이 다른 단열층을 적절히 형성할 수 있다. 그리고, 도장과 실크 스크린 인쇄등에 의한 강판(22)의 표면처리 베이킹 공정을 발포제(17)의 발포화 공정과 동시에 실행할 수 있으므로, 그 제조시간의 단축을 도모할 수 있다.In addition, by appropriately adjusting the amount of the blowing agent 17 in the resin sheet 20, the expansion ratio of the foam insulation layer 30 can be easily adjusted, and the thermal insulation performance can be appropriately controlled. In addition, by modifying the base resin in various ways, a heat insulating layer having different material properties can be appropriately formed. And the surface treatment baking process of the steel plate 22 by coating and silkscreen printing can be performed simultaneously with the foaming process of the foaming agent 17, and the manufacturing time can be shortened.

이상 설명한 것처럼 본 발명은, 표면처리를 한 강판을 포함한 강판의 적어도 한쪽면에 미발포된 발포제를 포함한 합성수지를 피착한 뒤, 이 강판을 공기조화기용 부재등에 형성가공하고, 그후에 상기 발포제를 발포시켜서 단열층을 형성시키므로 강판에는 미발포된 발포제를 포함한 합성수지를 전면적이고도 일정하게 피착할 수 있다.As described above, the present invention deposits a synthetic resin containing an unfoamed foaming agent on at least one side of a steel sheet including a steel sheet subjected to surface treatment, and then forms the steel sheet on an air conditioner member, and then foams the foaming agent. Since the insulating layer is formed, the synthetic steel including the unfoamed foaming agent can be deposited on the steel sheet in a full and constant manner.

따라서, 이 합성수지를 피착한 강판을 공기조화기용 부재등으로 형성가공하고, 그후에 미발포제를 발포시켜서 단열층을 형성할 때에는 이 단열층이 성형가공부재에 전면적이고도 일정하게 형성되어 종래예와 같이 성형가공품의 코너부에 단열층의 틈새를 형성하는 것을 방지할 수 있다. 그 결과, 본 발명에 따르면 단열시일성을 높일 수 있다.Therefore, when the steel sheet on which the synthetic resin is deposited is formed and processed into an air conditioner member or the like, and then foamed with a non-foaming agent to form a heat insulating layer, the heat insulating layer is formed on the molded processing member as a whole and uniformly. Formation of the clearance gap of a heat insulation layer can be prevented in a corner part. As a result, according to the present invention, heat insulation sealing property can be improved.

또한, 강판의 한쪽면에 도장과 실크스크린 인쇄등이 표면처리를 하는 경우에는 그 표면처리의 베이킹 공정을 발포제의 발포화 공정과 동시에 할 수 있으므로, 제조시간의 단축을 도모할 수 있는등 합리화를 도모할 수 있다.In addition, in the case of surface treatment such as painting and silkscreen printing on one side of the steel sheet, the baking process of the surface treatment can be performed at the same time as the foaming step of the blowing agent, so that the manufacturing time can be shortened. We can plan.
