Abstract
본 고안은 자동차의 천정판용 기재에 관한 것으로서, 종래에는 천정판 형태로 먼저 성형되는 골판지 기재의 강성을 유지하고자 기재를 이루는 상, 하판지의 내부에 얇은 은박지 등의 보강재를 전체적으로 또는 필요부위에만 부분적으로 내장시켜 사용하고 있으나, 이는 그 강도가 그리 강하지 못하여 생산된 천정판의 후변형률이 많이 발생하고, 특히 천정판의 테두리를 절단칼날로 트리밍할 때 천정판을 구성하는 표피지(10)의 발포포옴(20)과 골판지(30)의 접면부위가 쉽게 벌어지는 경향이 있어 절단칼날을 이용한 트리밍 작업을 하기가 어려웠다.The present invention relates to a substrate for a ceiling plate of a vehicle, and conventionally to reinforce the reinforcement material such as thin silver foil in the upper and lower boards of the upper and lower boards to form the substrate in order to maintain the rigidity of the corrugated substrate first formed in the form of a ceiling plate, or only partially Although it is used in a built-in, this strength is not so strong that a lot of deformation of the produced ceiling plate is generated, in particular, foam foam of the skin (10) constituting the ceiling plate when trimming the edge of the ceiling plate with a cutting blade The contact area between the 20 and the corrugated cardboard 30 tends to be easily opened, so it is difficult to trim the cutting blade.
따라서 본 고안은 발포포옴(120)과 부직포(110)로 이루어지는 표피재(100)가 표면에 부착되는 자동차의 천정판 성형용 기재를 구성함에 있어서, 지그재그 파상형으로 성형되는 속지(310)의 양면에 접착필름(341)(342)을 각각 부착하고 그 표이면에 평판의 상판지(320)와 하판지(330)를 융착하여 자동차의 천정판용 기재로 형성한 것으로서, 별도의 보강재 없이도 천정판으로의 성형성이 양호하고 후변성이 별로 없으면서도 절단칼날로 테두리 트리밍을 효과적으로 행할 수 있어 트리밍부위가 벌어지거나 휠 우려가 없음에 따라 트리밍 부위의 두께를 양호하게 유지할 수 있어 천정판 조립시 전후 글라스와의 밀착성을 높혀 자동차의 품질향상과 경쟁력을 높힐수 있는 것이다.Therefore, the present invention, when constructing a base plate for forming a ceiling plate of a vehicle in which the skin material 100 consisting of the foam foam 120 and the nonwoven fabric 110 is attached to the surface, both sides of the inlay 310 is formed in a zigzag wave shape. The adhesive films 341 and 342 are attached to each other, and the upper plate 320 and the lower plate 330 of the flat plate are fused to the surface of the plate to form the base plate of the vehicle. It has good moldability and does not have much rearrangement, so it is possible to effectively trim the rim with a cutting blade, so that the thickness of the trimming part can be maintained well as there is no fear of opening of the trimming part or wheels. It can improve the quality and competitiveness of automobiles by increasing the adhesion of automobiles.
Description
본 고안은 자동차의 천정판을 성형하기 위해 사용하는 기재에 관한 것으로써, 더욱 상세히는 자동차 천정판으로의 성형성을 높히고 소정형태로 성형된 천정판이 후변형되는 것을 방지하면서 그 테두리를 절단칼날로 원활히 트리밍할 수 있도록 강도를 유지시켜 주는 자동차의 천정판용 기재를 제공하기 위한 것이다.The present invention relates to a substrate used for forming a ceiling plate of an automobile, and more particularly, to improve the formability to the vehicle ceiling plate and to prevent the post-deformation of the ceiling plate formed in a predetermined shape with the cutting blade An object of the present invention is to provide a substrate for a ceiling plate of an automobile that maintains strength so that it can be trimmed smoothly.
일반적으로 자동차의 천정판은 주로 골판지 재질의 기재를 먼저 소정의 천정판 형태로 성형한 후 그 표면에 발포된 피이포옴(P.E Foam : 이하 발포포옴 이라칭함)과 화학섬유 재질의 부직포 등이 결합된 표피재를 융착하여 생산하고 있으며, 상기한 골판지 재질의 지재는 천정판 성형시의 성형성과 성형된 천정판의 강도를 원활하게 유지시키기 위해 사용되며, 또한 천정판의 후변형됨을 방지하기 위해 사용된다.In general, the ceiling plate of a car is mainly formed of a corrugated base material into a predetermined ceiling plate form, and then the foamed foam (PE foam) or chemical fiber nonwoven fabric is bonded to the surface thereof. It is produced by fusing the skin material, and the corrugated paper material is used to smoothly maintain the moldability and strength of the molded ceiling plate when forming the ceiling plate, and is also used to prevent post deformation of the ceiling plate. .
즉, 도 1 및 도 2에서와 같이 발포포옴(12)과 부직포(11)로 이루어진 표피재(10)의 이면에 부착되는 골판지 재질의 기재(30)는 대개 지그재그의 파상형으로 형성된 속지(31)의 표, 이면에 각각 평판으로된 상판지(32)와 하판지(33)가 각각 부착되는 구성으로 되어 있으며, 이때 상기 파상형의 속지(31)는 종이재질로만 되어 있고, 상기 속지(31)의 표면과 이면에 접면되어 부착되는 상판지(32)와 하판지(33)는 각각의 접면부쪽에 접착필름이 부착된 구조로 되어 있는데, 이러한 골판지 기재(30)의 강도는 접착필름이 부착된 상, 하판지의 강도에 의해 유지된다고 할 수 있다.That is, the corrugated base material 30 attached to the back surface of the skin material 10 made of the foam foam 12 and the nonwoven fabric 11, as shown in Figs. The upper plate 32 and the lower plate 33 made of flat plates are respectively attached to the table and the back surface of the table, wherein the wave-shaped inlay 31 is made of only a paper material, and the inlay 31 is attached thereto. The upper cardboard 32 and the lower cardboard 33, which are attached to the surface and the rear surface of the sheet), are attached to each of the contact portions, and the adhesive film is attached to each of the contact surfaces. The strength of the corrugated substrate 30 is that of the adhesive film. It can be said that it is maintained by the strength of the upper and lower cardboard.
그런데 상기와 같이 상, 하판지의 접촉면에 접착필름만을 부착한 경우에는 골판지 기재의 강도가 약하다고 할 수 있어 종래에는 도 2 에서와 같이 상, 하판지 (32)(33)중 어느 하나에 또는 두 판지(32)(33)에 다같이 얇은 은박지 등의 보강재(35)를 전체적으로 넣어 내장시키거나 또는 천정 램프 및 선바이저 등이 설치되는 소정부위에만 부분적으로 넣어 골판지 기재(30)의 강도를 보다 높게 유지시켜 사용하고 있다.However, when only the adhesive film is attached to the contact surface of the upper and lower cardboard as described above, it can be said that the strength of the corrugated substrate is weak, and conventionally, either one of the upper and lower cardboards 32, 33 or two cardboard as shown in FIG. Reinforcement materials 35 such as thin silver foils are embedded in (32) and (33) as a whole, or partially inserted only in predetermined portions where ceiling lamps and sun visors are installed to keep the strength of the corrugated substrate 30 higher. I use it.
하지만 상기와 같이 보강재(35)를 사용하는 경우에도 그 기재(30)의 강도가 양호하지 못하여 성형된 천정판의 후변형률이 많이 발생하고, 특히 성형된 천정판의 테두리를 절단칼날로 절단하여 트리밍할 때 천정판을 구성하는 표피재(10)의 발포포옴(12)과 골판지 기재(30)의 접면 테두리 부위가 쉽게 벌어지는 현상이 많이 발생하여 절단칼날을 이용한 트리밍 작업을 하기가 상당히 어려움에 따라 작업능률이 떨어짐은 물론 품질이 떨어져서 가격 및 품질 경쟁력이 낮게되는 문제점이 있었다.However, even when the reinforcing material 35 is used as described above, the strength of the base material 30 is not good, so that a large amount of back strain of the formed ceiling plate is generated, and in particular, the edge of the formed ceiling plate is cut with a cutting blade and trimmed. When a lot of phenomena in which the fold edge of the foam foam 12 and the corrugated cardboard substrate 30 of the skin material 10 constituting the ceiling plate is easily opened, the trimming work using a cutting blade is difficult to work. Not only is the efficiency lowered, but the quality was lowered, causing a problem of low price and quality competitiveness.
본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 천정판의 형태로 먼저 성형되는 골판지 기재의 성형성을 높히고 이러한 기재에 표피재를 융착하여 소정형태로 성형한 천정판이 휘거나 후변형되는 것을 효과적으로 방지하면서도 절단칼날로 테두리부위를 원활히 트리밍할 수 있을 정도로 천정판의 강도를 유지시켜 줄 수 있는 자동차의 천정판용 기재를 제공하는데 있다.The present invention is to solve the conventional problems as described above, the object of the present invention is to improve the formability of the corrugated substrate is first formed in the form of a ceiling plate and the ceiling plate molded in a predetermined form by fusing the skin material to such a substrate It is to provide a base plate for a ceiling plate of a vehicle that can maintain the strength of the ceiling plate to effectively prevent the bending or post-deformation to trim the edge portion with a cutting blade smoothly.
이와 같은 본 고안의 목적은 부직포와 발포포옴으로 이루어진 표피재가 표면에 부착되는 자동차 천정판 성형용 기재를 구성함에 있어서, 지그재그 파상형으로 성형되는 속지의 양면에 접착필름을 부착한 후 상기 속지의 표이면에 평판의 상판지와 하판지를 융착함으로써 달성되는 것이다.The purpose of the present invention is to construct a base plate for forming a vehicle ceiling plate, wherein the skin material consisting of a nonwoven fabric and a foam foam is attached to the surface, and after attaching the adhesive film to both sides of the inlay, which is formed in a zigzag wave shape, the table of the inlay It is achieved by fusing the top and bottom sheets of flat plate on the back side.
이러한 본 고안은 파상형의 속지가 양면에 융착된 접착필름에 의해 그 강도가 상당히 강해짐에 따라 종래처럼 상판지나 하판지의 내부에 은박지 등의 보강지를 별도로 넣지 않더라도 성형된 천정판이 후변형됨을 효과적으로 방지할 수 있고, 또한 절단칼날로 천정판의 테두리를 절단할 때 표피재와 기재의 테두리가 벌어질 우려가 없으므로 상기 목적을 효과적으로 달성할 수가 있다.The present invention is effective to prevent the deformed ceiling plate is not deformed even if the reinforcement such as tinfoil paper in the upper or lower paper as in the prior art as the strength is significantly stronger by the adhesive film fused on both sides of the inlay. In addition, when cutting the edge of the ceiling plate with a cutting blade, there is no fear that the edges of the skin material and the base material may be opened, thereby achieving the above object effectively.

이하 본 고안의 목적을 효과적으로 달성할 수 있는 바람직한 실시예를 들어 그 기술 구성 및 작용 효과를 첨부한 별첨의 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, which are attached to the accompanying drawings.
도 3 는 본고안의 기재와 표피재가 부착된 상태를 일부 확대하여 도시한 횡단면도로서, 이에 도시된 바와같이 본 고안은 발포포옴(120)과 부직포(110)로 이루어지는 표피재(100)가 표면에 부착되는 자동차의 천정판 성형용 기재를 구성함에 있어서, 지그재그 파상형으로 성형도는 속지(310)의 양면에 접착필름(341)(342)을 각각 부착하고 그 표이면에 평판의 상판지(320)와 하판지(330)를 융착하여 자동차의 천정판용 기재로 형성한 것을 특징으로 하는 것이다.Figure 3 is a cross-sectional view showing a partially enlarged state of the substrate and the skin material attached to the present invention, as shown in the present invention is a skin material 100 consisting of foam foam 120 and nonwoven fabric 110 is attached to the surface In constructing a base plate for forming a ceiling plate of a vehicle, in a zigzag wave shape, the molding degree is attached to the adhesive films 341 and 342 on both sides of the inlay 310, and the upper plate 320 of the flat plate on the back surface thereof. And the lower cardboard 330 is formed as a base plate for a vehicle.
이와같이 형성된 본 고안의 기재를 금형에 의해 소정형태의 천정판으로 성형하였을 때 지그재그의 파상형으로 된 속지(310)가 표이면에 융착된 접착필름(341)(342)에 의해 상당히 강한 강도를 유지하고 있으므로 상하판지(320)(330)의 내부에 종래처럼 은박지 등의 보강재를 넣지 않더라도 천정판 형태로의 성형성이 매우 양호하면서도 성형후의 후변형성이 별로 없는 것이다.When the substrate of the present invention formed as described above is molded into a ceiling plate of a predetermined form by a mold, the zigzag wavy inlay 310 maintains a very strong strength by the adhesive films 341 and 342 fused to the surface. Since the upper and lower cardboards 320 and 330 do not contain reinforcing materials such as silver foil as in the prior art, formability in the form of a ceiling plate is very good, and there is little post-forming after molding.
그리고 본고안은 상기와 같이 천정판 형태로 성형된 기재의 표면에 부직포(110)와 발포포옴(120)으로 이루어진 표피재(100)를 융착하여 천정판을 성형한 후 그 테두리를 절단칼날로 트리밍할 때에도 상기와 같이 파상형 속지(310)의 양면에 융착된 접착필름(341)(342)에 의해 강한 강도를 유지하고 있는 본 고안의 기재가 발포포옴(120)과 부직포(110)로 이루어진 표피재(100)를 매우 양호하게 받쳐줌에 따라 천정판의 테두리 트리밍 부위가 휘어지는 것을 방지할 수 있고, 트리밍부위의 발포포옴(120)과 본 고안의 기재 사이가 벌어질 우려가 없다.And the present proposal is to fuse the skin 100 consisting of a non-woven fabric 110 and a foam foam 120 on the surface of the substrate formed in the form of a ceiling plate as described above to form a ceiling plate trimming the edge with a cutting blade Even when the substrate of the present invention is maintained by the adhesive film 341, 342 fused on both sides of the corrugated inlay 310 as described above is the skin consisting of foam foam 120 and nonwoven fabric 110 By supporting the ash 100 very well, it is possible to prevent the edge trimming portion of the ceiling plate from bending, and there is no fear of the gap between the foam foam 120 of the trimming portion and the substrate of the present invention.
또한 상기와 같이 본 고안의 기재에 의해 천정판의 후변형성이 별로 없고 트리밍 부위가 벌어질 우려가 없음에 따라 천정판의 테두리 두께를 매우 양호하게 유지할 수 있으면서도 천정판 전체의 휨 현상을 효과적으로 방지할 수 있으므로 천정판을 조립할 때 전후 글라스와의 밀착성을 높힐 수 있어 자동차의 내장재 설치에 따른 품질을 상당히 높힐 수 있는 것으로서 그만큼 경쟁력이 향상되는 것이다.In addition, as described above, according to the present invention, since there is little post-deformation of the ceiling plate and there is no fear of opening of the trimming part, the edge thickness of the ceiling plate can be maintained very well, while effectively preventing the warpage of the entire ceiling plate. Therefore, when assembling the ceiling plate can improve the adhesion with the front and rear glass, which can significantly increase the quality of the interior of the car interiors, and the competitiveness will be improved.
이상에서 상술한 바와 같이 본 고안의 기재는 양면에 접착필름이 부착되어 강도가 양호하게 유지되는 파상형 속지에 의해 별도의 보강재를 사용하지 않고서도 천정판의 성형성이 양호하면서도 성형후의 후변형성이 별로 없으며, 특히 절단 칼날로 테두리를 트리밍하더라도 트리밍부위가 벌어지거나 휠 우려가 없으므로 트리밍 부위의 두께를 양호하게 유지할 수 있어 천정판 조립시 전후 글라스와의 밀착성을 높힐 수 있음에 따라 자동차의 품질을 향상시켜 경쟁력을 높힐 수 있는 것이다.As described above, the substrate of the present invention has a good shapeability of the ceiling plate and no post-deformation after molding, without using a separate reinforcement, by the wavy inlay in which the adhesive film is attached to both sides to maintain good strength. In particular, even when trimming the rim with a cutting blade, the trimming area does not have to be opened or the wheels are kept, so the thickness of the trimming area can be maintained well, and the adhesion of the glass to the front and rear glass can be improved when the ceiling plate is assembled. You can increase your competitiveness.
