건축용 단열판재 및 그 제조방법{Insulating panel for construction and manufacturing method for thereof}Insulating panel for construction and manufacturing method for

본 발명은 콘크리트 건물에서 실내를 구획하는 외벽체 및 층간 슬래브의 단열을 위하여 설치 사용되는 건축용 단열판재 및 그 제조방법에 관한 것으로, 특히 형태보존성과 난연성을 가지는 건축용 단열판재 및 그 제조방법에 관한 것이다.The present invention relates to a building insulation board and a method for manufacturing the building used for the insulation of the outer wall and interlayer slab partitioning the interior in a concrete building, and more particularly to a building insulation board having a shape preservation and flame retardant and a method for manufacturing the same.

일반적으로 콘크리트 건물에서 실내를 구획하는 벽체와 층간 슬래브에는 실내를 냉난방하는 데 따른 에너지 손실을 방지하고 결로현상의 발생을 방지하기 위하여 단열판재를 설치하고 있다.In general, the walls and interlayer slabs that partition the interior of a concrete building are installed with insulation plates to prevent energy loss and condensation from occurring in the room.

종래 건축용 단열판재로서는 통상적으로 일정한 두께를 가지는 합성수지 발포판재가 널리 사용되어 왔으며, 최근에는 합성수지 발포판재의 취약성을 보완하기 위하여 대한민국 공개특허공보 2002-0063084호와 같이 합성수지 발포판재의 일 표면에 합성수지 보강판재를 접합한 건축용 복합 단열판재가 개발되어 사용되고 있다.Conventionally, as a heat insulating board for construction, a synthetic resin foam sheet having a predetermined thickness has been widely used, and recently, in order to compensate for the weakness of the synthetic resin foam sheet, a synthetic resin reinforcement is formed on one surface of a synthetic resin foam sheet such as Korean Patent Laid-Open Publication No. 2002-0063084. Building composite insulation boards in which plate materials are bonded have been developed and used.

상기 합성수지 보강판재는 폴리프로필렌 재질로서, 서로 일정 간격을 두고 평행하게 배치되는 한 쌍의 판부와 이들 한 쌍의 판부를 연결하는 복수개의 연결부로 구성되어 한 쌍의 판부와 복수개의 연결부 사이에 복수개의 공간이 형성되는 구조로 되어 그 자체에도 단열효과가 있다.The synthetic resin reinforcing plate material is a polypropylene material, consisting of a pair of plate portions arranged in parallel at a predetermined interval from each other and a plurality of connecting portions connecting the pair of plate portions of the plurality of plate portions and a plurality of connection portions It has a structure that forms a space itself has an insulating effect.

이러한 종래의 건축용 복합 단열판재는 합성수지 발포판재와 합성수지 보강판재를 일체로 접합하여서 된 것으로, 벽체와 슬래브의 코너부에 설치되어 실내를 냉난방하는 데 따른 에너지의 손실을 방지하고 결로가 발생됨을 방지하여 주는 동시에, 벽체와 슬래브의 코너부에 매설된 상태에서 합성수지 보강판재를 통하여 이질의 마감용 벽지를 부착시켜서 마감할 수 있게 하여 주는 장점을 가지게 되었다.The conventional composite insulation board for building is made by bonding the synthetic foam plate and synthetic resin reinforcement plate integrally, it is installed in the corner of the wall and the slab to prevent the loss of energy due to heating and cooling the room and to prevent condensation At the same time, it has the advantage of being able to finish by attaching a heterogeneous finishing wallpaper through a synthetic resin reinforcement plate in the state of being embedded in the corners of the wall and the slab.

이러한 건축용 복합 단열판재는 합성수지 발포판재와 합성수지 보강판재를 접착제로 접합하게 되는데 합성수지 발포판재와 합성수지 보강판재 간의 접합력이 취약하여 서로 박리되는 현상이 발생하여 시공하자를 초래할 뿐만 아니라 건축물의 벽체와 슬래브의 코너부에 접착하였을 때 벽체와 슬래브를 구성하는 콘크리트 재질과 합성수지 보강판재를 구성하는 합성수지(통상 폴리프로필렌임) 재질 간의 접착력이 취약하여 시공후 벽체와 슬래브의 코너부에서 떨어져서 원하는 단열, 결로방지효과가 저하되고 시공하자를 초래하게 되는 문제점이 있었다.The composite insulation board for building is bonded with synthetic resin foam plate and synthetic resin reinforcement plate adhesive, but the weak bonding force between the synthetic resin foam plate and the synthetic resin reinforcement plate is weak, causing peeling of each other, resulting in the construction of the walls and slabs of the building. When bonded to the corner part, the adhesive force between the concrete material constituting the wall and the slab and the synthetic resin material (usually polypropylene) constituting the synthetic resin reinforcement plate is weak so that it is separated from the corner part of the wall and the slab after construction to prevent the desired insulation and condensation. There was a problem that is lowered and causing construction failure.

본 발명자는 대한민국 등록특허 10-654210호와 같이, 합성수지 보강판재를 구성하는 한 쌍의 판부의 표면에 합성수지 부직포 등의 섬유시트를 매립 및 표출되도록 한 합성수지 보강판재를 사용한 복합 단열판재를 개발하여 단열효과는 물론 시공성을 크게 향상시켰다.The present inventors developed a composite insulation board using a synthetic resin reinforcing plate material to be embedded and expressed a fiber sheet, such as a synthetic resin non-woven fabric on the surface of the pair of plate constituting the synthetic resin reinforcement plate material, such as Korea Patent Registration 10-654210 Of course, the workability was greatly improved.

그러나 위 등록특허의 복합 단열재는 폴리프로필렌 등으로 압출성형된 합성 수지 보강판재와 폴리프로필렌 등으로 제조된 합성수지 부직포 자체가 형태보존성이 낮기 때문에 복합 단열재를 제작하였을 때 전체적인 형태보존성이 저하되어 제작 및 시공과정에서 형태의 변경으로 인해 제조불량 및 시공하자를 초래하는 문제점이 있다.However, the composite heat insulating material of the above registered patent is because the synthetic resin reinforcement plate extruded with polypropylene and the synthetic resin nonwoven fabric itself made of polypropylene have low form preservation. Due to the change in form in the process there is a problem that leads to poor manufacturing and construction.

또한 상술한 종래의 건축용 단열재들은 그 구성요소인 합성수지 발포판재, 합성수지 보강판재 및 합성수지 부직포가 불연성이나 난연성을 보유하고 있지 않기 때문에 불연재나 난연재로서 사용할 수 없는 제약이 있다.In addition, the above-described conventional building insulation has a restriction that can not be used as a nonflammable material or a flame retardant material because the synthetic resin foam plate material, synthetic resin reinforcement plate material and synthetic resin nonwoven fabric does not have a nonflammable or flame retardant.

따라서 본 발명은 복합 단열재의 형태보존성을 크게 향상시켜 제조불량과 시공하자를 크게 저하시킬 수 있도록 한 건축용 단열판재 및 그 제조방법을 제공하려는 것이다.It is therefore an object of the present invention to provide a building insulation board and a method for manufacturing the same, which greatly reduce the shape preservation of the composite insulation and greatly reduce manufacturing defects and construction defects.

본 발명의 다른 목적은 합성수지 발포판재에 접합하여 복합 단열재를 제작하였을 경우에도 복합 단열재의 전체적인 형태보존성을 크게 향상시켜 제조불량과 시공하자를 크게 저하시킬 수 있도록 한 건축용 단열판재 및 그 제조방법을 제공하려는 것이다.It is another object of the present invention to provide a building insulation board and a method of manufacturing the same so as to significantly reduce the manufacturing defects and construction defects by greatly improving the overall shape preservation of the composite insulation even when the composite insulation is manufactured by bonding to a synthetic foam sheet.

본 발명의 또 다른 목적은 합성수지 발포판재와 접합하여 사용할 경우 접합불량이나 휨현상을 배제하고 생산성을 향상시킬 수 있도록 한 건축용 단열판재 및 그 제조방법을 제공하려는 것이다.Still another object of the present invention is to provide a building insulation board and a method for manufacturing the same, which can be used to improve productivity by excluding a bonding defect and warpage when used in combination with a synthetic resin foam plate.

본 발명은 상술한 목적을 달성하기 위하여, 합성수지 판재와, 상기 합성수지 판재의 표리면 중 적어도 어느 일측에 매립되는 다공성 불연보강재와, 상기 합성수지 판재의 표리면 측에 일부가 매설된 상태로 표출되며 난연재가 코팅된 합성수지 부직포를 포함하여 구성되는 건축용 단열판재를 제공한다.In order to achieve the above object, the present invention is a synthetic resin plate, a porous non-combustible reinforcement is embedded in at least one side of the front and back surfaces of the synthetic resin plate, and the part is embedded in the front and back surface side of the synthetic resin plate is expressed in a flame retardant material It provides a building insulation board comprising a coated synthetic resin non-woven fabric.
