There is a structure bonded by liquid adhesive.
이러한 구조의 출입문에 있어서, ①의 경우 비철계에 비해 무겁고 용접후의 변형이 크며, 제작공정이 복잡하다. 또, ②의 경우는 중량이 ①에 비해 가벼우나 표면재인 스테인레스 강판과 알루미늄 하니컴 코어 사이의 이액형 수지의 조직구조가 치밀한 금속에 균일하게 함침되지 못하기 때문에 접착력이 낮아 박리현상이 두드러지는 경향이 있다.In the door of this structure, ① is heavier than the nonferrous system, the deformation after welding is large, and the manufacturing process is complicated. In the case of ②, however, the weight is lighter than that of ①, however, since the structure of the two-component resin between the stainless steel sheet and the aluminum honeycomb core, which is a surface material, is not uniformly impregnated with a dense metal, the adhesion is low and the peeling phenomenon tends to be outstanding. have.

Alternatively, the structural technology of joining the interface between the surface material and the core material with a thermosetting resin adhesive sheet using a nomax honeycomb core as a core material is applied to a railway vehicle passage door to increase durability and suppress peeling.
본 발명은 상·하부 표면재에 모두 스테인레스 강판과 알루미늄판을 열경화성수지접착형 시트로 접합한 복합판넬 또는 상·하부 표면재중 한쪽 표면재를 알루미늄판으로 하고, 다른 한쪽 표면재는 앞서 말한 복합판넬을 사용하여 심재인 알루미늄 하니컴 코어, P.M.I 발포체 코어 또는 노맥스 하니컴 코어등과 상·하부 표면재의 알룸늄판 쪽이 서로 마주 보도록 표면재와 심재의 경계면을 열경화성수지접착형 시트로 접합함으로써 접착제의 균일한 함침으로 표면재와 심재간의 박리현상을 억제하고 표면강도를 높인 것이다.According to the present invention, a composite panel obtained by joining a stainless steel sheet and an aluminum plate to a thermosetting resin adhesive sheet on both the upper and lower surface materials, or one of the upper and lower surface materials as an aluminum plate, and the other surface material using the above-described composite panel The surface material and core material are bonded by the thermosetting resin adhesive sheet by bonding the interface between the surface material and the core material with a thermosetting resin adhesive sheet so that the aluminum honeycomb core, PMI foam core or nomax honeycomb core, and the aluminum plate of the upper and lower surface materials face each other. It inhibits the peeling phenomenon of the liver and increases the surface strength.

1, 1a-표면재(스테인레스 강판)1, 1a-surface material (stainless steel sheet)
2(a, b, c)-열경화성 수지 접착 시트2 (a, b, c) -thermosetting resin adhesive sheet
3, 3a-표면재(알루미늄판)3, 3a-surface material (aluminum plate)
4-심재(알루미늄제 하니컴 코어, P.M.I(폴리메트 아크릴 이미드) 발포체 코어 또는 노맥스 하니컴 코어)4-core material (aluminum honeycomb core, P.M.I (polymethacrylic imide) foam core or nomax honeycomb core)
제 1도에서, 스테인레 강판(1)의 이면에 열경화성수지접착형 시트(2)를 적층 이어서 알루미늄판(3)을 적층하여 접합한 복합판재와 알루미늄판을 상·하부 표면재로 하고, 이들 표면재 사이에 알루미늄 하니컴 코어, P.M.I발포체 코어 또는 노맥스 하니컴 코어를 심재(4)로 하는 표면재와 심재 사이의 경계면에 열경화성수지접착형 시트를 적층하여 표면재와 심재를 접합한다.In FIG. 1, the composite plate material and the aluminum plate which laminated | stacked the thermosetting resin adhesive sheet | seat 2 on the back surface of the stainless steel plate 1, and laminated | stacked the aluminum plate 3 by lamination | stacking are these surface materials The thermosetting resin adhesive sheet is laminated on the interface between the surface material including the aluminum honeycomb core, the PMI foam core, or the nomax honeycomb core as the core material 4 and the core material, and the surface material and the core material are bonded to each other.
상기와 같이 스테인레스 강판과는 이질적이고 구조상 작은 단면적 때문에 접합강도가 낮을 수 밖에 없는 알루미늄제 하니컴 코어를 접합함에 있어서 평판상의 알루미늄판을 미개체로 하여 간접적으로 접합하고, 열경화성 수지접합형 시트를 사용함으로써 이액상 접착수지와는 달리 접착수지 함침이 균일하게 이뤄지므로 접합강도가 한층 증대되는 것이다.As described above, in joining an aluminum honeycomb core that is heterogeneous with a stainless steel sheet and has a low bonding strength due to its small cross-sectional area, it is indirectly bonded by using a flat aluminum plate as an undivided object and using a thermosetting resin bonded sheet. Unlike two-liquid adhesive resin, the adhesive resin impregnation is made uniform, so the bonding strength is further increased.
다른 실시예로서는 제 2도에 나타난 바와 같이, 스테인레스 강판(1)의 일면에 열경화성수지접착형 시트(2)를 적층한 후 알루미늄판을 적층 접합하고, 상기 알루미늄판(3)의 이면에도 열경화성수지접착형 시트(2a)를 적층한 후 알루미늄 하니컴 코어, P.M.I 발포체 또는 노맥스 하니컴 코어(4)의 이면에도 열경화성수지접착형 시트(2b)를 적층한 다음에 다시 알루미늄판(3a)을 적층 접합하고, 그 이면에 열경화성수지접착형 시트(2c)와 스테인레스 강판(1a)을 적층 접합한다.As another embodiment, as shown in FIG. 2, after the thermosetting resin adhesive sheet 2 is laminated on one surface of the stainless steel sheet 1, an aluminum plate is laminated and bonded, and the thermosetting resin adhesive is also bonded to the back surface of the aluminum plate 3. After laminating the mold sheet 2a, the thermosetting resin adhesive sheet 2b was also laminated on the back surface of the aluminum honeycomb core, PMI foam or nomax honeycomb core 4, and then the aluminum plate 3a was laminated and bonded again. The thermosetting resin adhesive sheet 2c and the stainless steel plate 1a are laminated together on the back surface.
각 실시예에서 스테인레스 강판(1, 1a)은 내마모성과 내식성이 우수한 두께 0.3~0.8㎜의 얇은 판이다.In each embodiment, the stainless steel sheets 1 and 1a are thin plates having a thickness of 0.3 to 0.8 mm excellent in wear resistance and corrosion resistance.
제 2실시예에서 얻어지는 출입문재는 제 1실시예의 출입문재에 비해 강도가 우수하고, 표면이 외상(긁힘)으로부터 안전해지는 이점이 더 있다.The door material obtained in the second embodiment is superior in strength to the door material of the first embodiment, and further has the advantage that the surface is safe from trauma (scratching).
이상 설명한 바와 같은 본 발명은 표면재인 스테인레스강판과 심재인 알루미늄제 하니컴 코어, P.M.I 발포체 코어 또는 노맥스 하니컴 코어를 접촉면적이 넓고 알루미늄제 하니컴 코어와는 친화성을 가진 알루미늄판을 매개체로 하여 접착제로 접합한 것으로, 일반 압연강재 또는 스테인레스 강재로 프레임에 내·외판을 용접한 구조의 출입문재 또는 스테인레스 강판을 표면재로 하고 프레임과의 사이에 알루미늄 하니컴 코어를 접합한 구조로 된 종래 철도차량용 출입문재에 비해 훨씬 가벼우면서도 튼튼하다.As described above, the present invention is a stainless steel sheet as a surface material and a honeycomb core made of aluminum, a PMI foam core, or a nomax honeycomb core made of a core material, which has a wide contact area and is bonded to the aluminum plate having an affinity with an aluminum honeycomb core as an adhesive. Compared to conventional railway vehicle door doors, the door door material is made of ordinary rolled steel or stainless steel welded to the frame with a stainless steel sheet, and the aluminum honeycomb core is bonded to the frame. Much lighter and stronger.
또, 표면재인 스테인레스 강판과 심재인 알루미늄제 하니컴 코어, P,M.I 발포체 코어 또는 노맥스 하니컴 코어를 접촉면적이 넓고 알루미늄 하니컴 코어와는 친화성을 가진 알루미늄판을 매개체로 하여 접착제로 접합한 것의 알루미늄판 이면에 스테인레스 강판을 덧붙인 출입문재는 한쪽에만 스테인레스강판을 붙인 철도차량용 출입문재에 비해 표면의 외상을 막는데 유효하다.In addition, an aluminum sheet in which a stainless steel plate, which is a surface material, and a honeycomb core made of aluminum, a P, MI foam core, or a nomax honeycomb core, which are bonded to each other with an adhesive is made of an aluminum plate having a wide contact area and affinity with the aluminum honeycomb core. Door material with stainless steel plate on the back side is more effective in preventing surface trauma than door material for railroad cars with stainless steel plate on one side.
본 발명은 철도차량용 출입문재에 관한 것이며, 특히 스테인레스 강판과 알루미늄판을 열경화성수지접착형 시트로 접합한 복합판이나 알루미늄판을 표면재로 하고 알루미늄 하니컴 코어, P.M.I(폴리메트 아크릴 이미드) 발포체 코어 도는 노맥스 하니컴 코어를 심재로 하여 표면재와 심재의 경계면을 열경화성수지접착형 시트로 접합하는 구조기술을 철도량 통로문에 적용하여 내구성 증대와 차량경량화를 제시하는데 그 목적이 있다.TECHNICAL FIELD The present invention relates to a doorway material for a railroad car, and in particular, an aluminum honeycomb core, a PMI (polymethacrylic imide) foam core, or a composite plate or an aluminum plate in which a stainless steel sheet and an aluminum plate are bonded with a thermosetting resin adhesive sheet. The purpose of this study is to propose the increase of durability and the weight reduction of vehicle by applying structural technology to join the interface between the surface material and the core material by thermosetting resin adhesive sheet using the nomax honeycomb core as the core material.
