Description

중공형 패널 {HOLLOWNESS TYPE PANEL}Hollow Panel {HOLLOWNESS TYPE PANEL}

본 발명은 중공형 패널에 관한 것으로서, 보다 상세하게는 내부에 소정의 공간부가 형성되어 선박이나 철도차량 등의 바닥재 또는 천정재로 사용되는 중공형 패널에 관한 것이다.The present invention relates to a hollow panel, and more particularly, to a hollow panel used as a floor or ceiling material such as a ship or a railroad car with a predetermined space formed therein.

일반적으로, 중공형 패널은 평활도, 경량성, 내구성, 흡음성 및 내수성 등은 물론이고 시공성이 우수한 복합소재로서, 여러 산업분야에서 다양하게 사용되고 있다.In general, the hollow panel is a composite material having excellent workability as well as smoothness, light weight, durability, sound absorption and water resistance, and is widely used in various industrial fields.

이러한 중공형 패널의 대표적인 것 중의 하나의 허니컴 패널(Honeycomb Panel)이다.One of the typical ones of such a hollow panel is a honeycomb panel.

종래의 중공형 패널은 대부분은 심재의 상·하부에 플레이트 형상의 표피재가 한 쌍으로 부착되어 있는 구조를 지니고 있으며, 심재는 허니컴 형상으로 이루어진다.Most of the conventional hollow panel has a structure in which a plate-like skin material is attached to the upper and lower portions of the core material in pairs, and the core material has a honeycomb shape.

상기와 같은 중공형 패널은 나사나 볼트 등과 같은 결합수단에 의해 구조물 과 결합되나, 심재가 허니컴 형상을 가짐으로써 결합수단의 취부가 용이하지 않음은 물론이고 결합수단의 결합상태를 견고하고 안정적으로 유지하는 데 한계가 있다.The hollow panel as described above is coupled to the structure by a coupling means such as a screw or bolt, but since the core material has a honeycomb shape, mounting of the coupling means is not easy, as well as maintaining a firm and stable coupling state of the coupling means. There is a limit to this.

또한, 중공형 패널의 구조적 특징상 가장자리 부위의 강도가 상대적으로 취약하다는 단점이 있다.In addition, there is a disadvantage that the strength of the edge portion is relatively weak due to the structural characteristics of the hollow panel.

그리고 중공형 패널의 심재 및 표피재가 통전성 재질로 이루어짐으로 인해, 절연 기능이 저하되어 인체나 각종 설비에 전기적 부하가 발생될 가능성이 높다는 문제점이 있다.In addition, since the core material and the skin material of the hollow panel are made of an electrically conductive material, there is a problem in that an insulation function is deteriorated and electrical loads are likely to be generated in the human body or various equipment.

이는 결국, 중공형 패널의 기능성 및 사용성을 상대적으로 저하시키는 결과를 초래한다.This, in turn, results in a relatively low functionality and usability of the hollow panel.

본 발명은 절연 기능 및 가장자리 부위의 국부적 강도를 향상시킴과 아울러 구조물과의 결합시 나사나 볼트의 취부가 용이한 중공형 패널을 제공하고자 하는 데 그 목적이 있다.It is an object of the present invention to provide a hollow panel which improves the insulation function and the local strength of the edge portion and is easy to attach screws or bolts when combined with the structure.

본 발명에 따른 중공형 패널은 중공형의 심재; 상기 심재의 상·하부에 부착되는 표피재; 상기 심재의 가장자리에 결합되어, 상기 표피재 사이에 개재되는 에지프레임을 포함하며, 상기 에지프레임은 열경화성 수지가 침투되어 있는 다단 적층구조의 글래스매트인 것을 그 기술적 특징으로 한다.Hollow panel according to the present invention is a hollow core material; Skin material attached to upper and lower portions of the core material; The edge frame is coupled to the edge of the core material, the edge frame interposed between the skin material, the edge frame is characterized in that the glass mat of a multi-stage laminated structure in which the thermosetting resin penetrates.

상기 열경화성 수지는 에폭시, 실리콘, 불포화 폴리에스테르 및 페놀 중 어느 하나인 것이 바람직하다.It is preferable that the said thermosetting resin is any one of an epoxy, a silicone, unsaturated polyester, and a phenol.

상기 에지프레임은 글래스매트를 열경화성 수지에 함침하는 단계; 열경화성 수지가 함침된 글래스매트를 60∼100℃에서 반경화 상태로 건조하는 단계; 건조된 글래스매트를 다단으로 적층하는 단계; 적층된 글래스매트를 가압 성형하는 단계를 거쳐 제조되는 것이 바람직하다.The edge frame is impregnated with a glass mat in a thermosetting resin; Drying the glass mat impregnated with the thermosetting resin in a semi-cured state at 60 to 100 ° C .; Stacking the dried glass mat in multiple stages; It is preferable that the laminated glass mat is manufactured through pressure molding.

상기 에지프레임은 글래스매트를 다단으로 적층하는 단계; 적층된 글래스매트를 비닐로 밀봉하는 단계; 밀봉된 비닐에 진공펌프관 및 수지주입관을 연결하는 단계; 진공펌프관을 통해 밀봉된 비닐 내부의 공기를 제거하고, 그 압력을 이용하 여 수지주입관을 통해 열경화성 수지를 주입하는 단계를 거쳐 제조되는 것이 바람직하다.Stacking the glass mat in multiple stages; Sealing the laminated glass mat with vinyl; Connecting the vacuum pump tube and the resin injection tube to the sealed vinyl; It is preferable to remove the air inside the sealed vinyl through the vacuum pump tube, and to inject the thermosetting resin through the resin injection tube using the pressure.

본 발명에 따르면, 에지프레임을 통해 중공형 패널 가장자리 부위의 국부적 강도를 향상시킬 수 있을 뿐 아니라 나사나 볼트 등을 통한 구조물과의 결합이 용이하다.According to the present invention, not only the local strength of the hollow panel edge portion can be improved through the edge frame, but also the coupling with the structure through screws or bolts is easy.

또한, 에지프레임의 재질적 특성으로 인해 절연 기능이 한층 강화됨으로써 인체나 각종 설비에 전기적 부하가 발생되는 것을 간편하고 효율적으로 방지할 수 있다.In addition, the insulation function is further strengthened due to the material properties of the edge frame, thereby easily and efficiently preventing electrical loads from occurring in the human body or various facilities.

그로 인해, 중공형 패널의 기능성 및 사용성을 상대적으로 향상시킬 수 있다.Therefore, the functionality and usability of the hollow panel can be relatively improved.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1 내지 도 3에 도시된 바와 같이, 본 발명에 따른 중공형 패널은 중공형의 심재(20); 심재(20)의 상·하부에 부착되는 표피재(30a,30b); 심재(30a,30b)의 가장자리에 결합되어, 표피재(30a,30b) 사이에 개재되는 에지프레임(40)을 포함하여 구성된다.As shown in Figures 1 to 3, the hollow panel according to the present invention is a hollow core material 20; Skin materials 30a and 30b attached to upper and lower portions of the core material 20; It is coupled to the edge of the core material (30a, 30b), and comprises an edge frame 40 interposed between the skin material (30a, 30b).

심재(20)는 플레이트형의 허니컴(Honeycomb) 구조를 가지며, 필요에 따라 엠보싱(Embossing) 또는 물결무늬(Corrugation) 구조 등을 선택적으로 적용할 수 있다.The core 20 has a plate-type honeycomb structure, and optionally, embossing or corrugation structure may be selectively applied.

심재(20)의 재질로는 알루미늄과 같은 금속 또는 아라미드 계열의 합성수지가 사용될 수 있으며, 가격 측면에서 다소 불리한 점은 있지만 절연성 및 경량성이 상대적으로 우수한 아라미드 계열의 합성수지 재질을 사용하는 것이 바람직하다.As the material of the core material 20, a metal such as aluminum or an aramid-based synthetic resin may be used, but it is preferable to use an aramid-based synthetic resin material which is relatively disadvantageous in terms of cost but relatively excellent in insulation and light weight.

표피재(30a,30b)는 내구성 및 내강도성은 물론이고 절연성이 우수한 알루미늄 등과 같은 금속 재질 또는 페놀이나 멜라민 등과 같은 비금속 재질을 선택적으로 사용 가능하다.The skin materials 30a and 30b may selectively use a metal material such as aluminum having excellent durability as well as durability and strength resistance, or a nonmetal material such as phenol or melamine.

에지프레임(40)은 심재(20)의 가장자리를 완전히 둘러싸도록 결합되며, 바(bar) 형상을 가진다.The edge frame 40 is coupled to completely surround the edge of the core 20, and has a bar shape.

에지프레임(40)은 가장자리 부위의 국부적 강도를 향상시킴과 아울러 나사나 볼트의 취부를 용이하게 하기 위한 것이며, 동시에 절연 기능을 강화하기 위한 것이다.The edge frame 40 is intended to enhance local strength of the edge portion and to facilitate mounting of screws or bolts, and at the same time to reinforce the insulation function.

이에 따라, 에지프레임(40)은 열경화성 수지가 내부에 침투되어 있는 다단 적층구조의 글래스매트(glass mat)가 사용된다. 그리고 글래스매트에 침투되는 열경화성 수지로는 에폭시, 실리콘, 불포화 폴리에스테르 및 페놀 중 어느 하나를 사용하는 것이 바람직하다.Accordingly, the edge frame 40 uses a glass mat having a multi-stage lamination structure in which a thermosetting resin has penetrated therein. And as a thermosetting resin which permeates a glass mat, it is preferable to use any one of an epoxy, a silicone, unsaturated polyester, and a phenol.

한편, 도면에 도시되어 있는 에지프레임(40)은 접착제 등에 의해 서로 연결되어 있는 구조를 가지나, 이는 일 실시예에 불과한 것으로 일체형 구조를 가질 수 도 있다.On the other hand, the edge frame 40 shown in the drawing has a structure that is connected to each other by an adhesive or the like, which is only one embodiment may have an integrated structure.

그리고 중공형 패널의 핵심 구성인 에지프레임의 제조방법을 살펴보면 하기와 같다.And look at the manufacturing method of the edge frame which is the core configuration of the hollow panel as follows.

① 제1단계(S1) : 글래스매트를 열경화성 수지에 함침하는 단계.① first step (S1): impregnating the glass mat into the thermosetting resin.

이 때, 열경화성 수지로는 에폭시, 실리콘, 불포화 폴리에스테르 또는 페놀 등이 사용된다.At this time, epoxy, silicone, unsaturated polyester or phenol is used as the thermosetting resin.

② 제2단계(S2) : 열경화성 수지가 함침된 글래스매트를 반경화 상태로 건조하는 단계;② second step (S2): drying the glass mat impregnated with the thermosetting resin in a semi-cured state;

이 때, 글래스매트의 건조는 60∼100℃ 온도조건에서 이루어지는 것이 바람직하다.At this time, the glass mat is preferably dried at a temperature of 60 to 100 ° C.

③ 제3단계(S3) : 건조된 글래스매트를 일정의 길이로 절단한 후, 다단으로 적층하는 단계;③ third step (S3): cutting the dried glass mat to a predetermined length, and then laminating in multiple stages;

④ 제4단계(S4) : 적층된 글래스매트를 프레스를 통해 열 가압하여 일체로 성형하는 단계.④ fourth step (S4): the step of forming integrally by thermally pressing the laminated glass mat through a press.

이상에서 설명한 총 4단계를 거침으로써 에지프레임(40)의 제조과정이 완료된다.By going through the four steps described above, the manufacturing process of the edge frame 40 is completed.

또한, 중공형 패널의 핵심 구성인 에지프레임의 제조방법의 다른 실시예를 설명하면 하기와 같다.In addition, another embodiment of the manufacturing method of the edge frame that is the core configuration of the hollow panel is as follows.
