Description

건축용 심재 및 그 제조방법{CORE MATERIALS FOR BUILDING AND METHOD FOR MANUFACTURING THE SAME}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a core material for construction,

본 발명은 건축물에 사용되는 심재 및 그 제조방법에 관한 것으로서, 특히 심재층 상, 하측으로 각각 단열재층이 형성되는 건축용 심재 및 그 제조방법에 관한 것이다.The present invention relates to a core material used in a building and a manufacturing method thereof, and more particularly, to a core material for construction in which a heat insulating material layer is formed on each of a core layer and a lower layer, and a manufacturing method thereof.

일반적으로, 심재는 건축물의 벽면 및 출입문 등에 사용될 수 있다.Generally, the core material can be used for a wall of a building, a door, and the like.

일 예를 들어, 샌드위치 판넬은 강판과 강판 사이에 심재를 넣어 접착 또는 발포시켜 만들어진다.For example, a sandwich panel is made by sticking a core material between a steel sheet and a steel sheet and bonding or foaming them.

상기 샌드위치 판넬의 심재는 주로 폴리우레탄폼, 스치로폼 등이 많이 사용되고 있으며, 이러한 폴리우레탄폼, 스치로폼은 단열성이 우수한 제품이지만 유기질 재료의 연소 특성으로 인하여 화재 발생시 유해가스가 다량 발생하여 질식사를 유발할 수 있는 등의 우려가 높고, 가연성이 높아 대형 화재로 발전될 가능성이 높아 점차적으로 그 활용성이 떨어지고 있다.The polyurethane foam and the styrofoam are excellent in heat insulation property. However, due to the combustion characteristics of the organic material, a large amount of noxious gas is generated when a fire occurs, And it is highly likely to be developed into a large-scale fire due to its high flammability, so that its utilization is gradually deteriorating.

또한 샌드위치 판넬의 흡음성을 향상시키기 위해 폴리우레탄폼, 스치로폼으로 이루어지는 심재의 압축강도를 조절하여 사용하여 왔다.Also, in order to improve the sound-absorbing property of the sandwich panel, the compression strength of the core material made of polyurethane foam and styrofoam has been used.

하지만 심재의 흡음성을 구비하기 위하여 압축강도를 조절하거나, 대형 화재의 발생을 줄이기 위해 가연성이 높은 폴리우레탄폼, 스치로폼에 난연제를 도포하는 등의 별도의 공정을 필요로 한다.However, in order to adjust the compressive strength to reduce the occurrence of large fires, it is necessary to apply a flame retardant to polyurethane foams and styrofoam, which have high flammability.

따라서 이러한 공정이 늘어남에 따라 심재의 생산단가가 현저하게 높아져 가격경쟁력이 저하되는 단점이 있어왔다.Therefore, as the process increases, the production cost of the core material becomes remarkably high, and the price competitiveness is deteriorated.

대한민국 공개특허 제10-2004-0082770호 (2004.09.30)Korean Patent Publication No. 10-2004-0082770 (September 30, 2004)

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, 상, 하측으로 각각 단열재층이 형성되고, 상기 단열재층 사이로 난연 및 흡음기능이 구비되는 심재층이 구비되어 난연기능과 흡음기능이 향상되는 건축용 심재 및 그 제조방법을 제공하는데 그 목적이 있다.Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a heat insulating material layer on upper and lower sides, And a method for manufacturing the same.

또한 단열재층과 심재층을 접착하는 바인더로 하여금 난연기능이 강화되면서 접착강도가 향상되는 건축용 심재 및 그 제조방법을 제공하는데 또 다른 목적이 있다.Another object of the present invention is to provide a core for a construction in which a binder for bonding a heat insulating material layer and a core material layer has improved flame retardancy and adhesion strength and a method for manufacturing the same.

상기와 같은 목적을 실현하기 위하여 본 발명은, 강판과 강판 사이에 구비되는 심재에 있어서, 글라스 울, 미네랄 울, 암면 중 적어도 하나로 이루어지는 심재층; 및 상기 심재층의 상, 하측에 각각 구성된 단열재층을 제공한다.In order to achieve the above object, the present invention provides a core material provided between a steel sheet and a steel sheet, the core layer comprising at least one of a glass wool, a mineral wool and a rock surface; And a heat insulating material layer formed on upper and lower sides of the core layer, respectively.

또한 강판과 강판 사이에 구비되는 건축용 심재의 제조방법에 있어서, 글라스울, 미네랄울, 암면 중 어느 하나가 폼 형태로 이루어지는 심재층과 단열재층을 준비하는 준비단계; 상기 심재층의 두께가 상기 단열재층의 두께 이하가 되도록 가공하는 가공단계; 상기 심재층 및 단열재층의 외면에 코팅제를 도포한 후 건조시키는 코팅단계; 및 상기 심재층 및 상기 단열재층을 바인더를 이용하여 접착하는 접착단계를 제공한다.Also, the present invention provides a method of manufacturing a core material for construction provided between a steel sheet and a steel sheet, comprising the steps of: preparing a core material layer and a heat insulating material layer, each of which is made of a foamed material such as glass wool, mineral wool or rock wool; A processing step of processing the core material layer so that the thickness of the core material layer is equal to or less than the thickness of the heat insulating material layer; A coating step of applying a coating agent to the outer surface of the core material layer and the heat insulating material layer, followed by drying; And a bonding step of bonding the core layer and the heat insulating layer using a binder.

전술한 바와 같이 본 발명에 따르면, 단열재층과 더불어 상기 단열재층 사이로 난연 및 흡음기능이 구비되는 심재층이 구비되어 난연기능과 흡음기능이 향상되고, 구조적인 강도 및 중량이 가벼워 시공과 운반성이 우수한 건축용 심재를 얻을 수 있는 효과가 있다.As described above, according to the present invention, since a core layer having flame retardancy and sound absorption function is provided between the heat insulating material layers in addition to the heat insulating material layer, the flame retarding function and the sound absorbing function are improved and the structural strength and weight are light, It is possible to obtain an excellent structural core material.

또한 단열재층과 심재층을 접착하는 바인더로 인해 난연기능이 강화되면서 접착강도 또한 향상되어 양질의 건축용 심재를 얻을 수 있는 효과가 있다.Further, since the binder for bonding the heat insulating layer and the core layer enhances the flame retardant function, the bonding strength is also improved, and thus a high quality core for construction can be obtained.

이하 본 발명의 실시를 위한 구체적인 내용을 첨부한 도면을 참조하여 더욱 상세하게 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 건축용 심재의 바람직한 형태를 나타내는 사시도이고, 도 2는 본 발명에 따른 건축용 심재의 바람직한 형태를 나타내는 분해사시도로서, 여기서 본 발명에 따른 건축용 심재는 샌드위치 판넬을 이루는 강판과 강판 사이에 구성되어 단열성 및 흡음성을 구비하도록 구성된다.FIG. 1 is a perspective view showing a preferred embodiment of the core for construction according to the present invention, FIG. 2 is an exploded perspective view showing a preferred embodiment of the core for construction according to the present invention, wherein the core for construction according to the present invention comprises a steel plate, So as to have a heat insulating property and a sound absorbing property.

이를 위해 도 1, 2에 도시된 바와 같이 본 발명은 상, 하측으로 각각 경량이어서 가공성 및 취급성이 뛰어나고 단열성이 우수한 것이 특징인 단열재층(10)이 구비된다.To this end, as shown in FIGS. 1 and 2, the present invention is provided with a heat insulating material layer 10 characterized by being light weighted on the upper and lower sides, respectively, and excellent in workability and handling property and excellent in heat insulation.

상기 단열재층(10)은 EPS(Expanded Poly-styrol), 난연 EPS, 우레탄 폼, 페놀 폼, 무기재 혼합 페놀폼, 비드법 2종 폼 중에서 적어도 하나로 이루어질 수 있다.The heat insulating material layer 10 may be formed of at least one of EPS (Expanded Poly-styrol), flame retardant EPS, urethane foam, phenol foam, inorganic re-mixed phenol foam, and bead type foam.

또한 상기 단열재층(10) 사이로 글라스울, 미네랄울, 암면 중 어느 하나로 이루어지는 심재층(20)이 포함된다.Also, the core layer 20 made of any one of glass wool, mineral wool, and rock wool is included between the heat insulating layers 10.

상기 심재층(20)을 이루는 글라스울, 미네랄울, 암면은 모두 무기섬유로서 유기섬유에 비하여 내열성이 크고 흠음기능과 더불어 난연기능이 우수한 것이 특징이다.The glass wool, mineral wool, and rock wool which constitute the core layer 20 are all inorganic fibers, which are superior in heat resistance to organic fibers and have excellent flame retardancy as well as brittle function.

따라서 건축물의 벽면 또는 지붕을 이루는 샌드위치 판넬의 심재에 유입된 음파는 심재층(20)에 의해 감쇄됨으로서 소음을 흡음하게 되는 것이다.Therefore, the sound waves introduced into the core of the sandwich panel constituting the wall or the roof of the building are attenuated by the core layer 20, so that noise is absorbed.

또한 내열성이 좋은 무기섬유인 심재층(20)이 심재 내부에 구비됨으로서 고열에 의해 샌드위치 판넬에 다소간의 수축작용이 발생되어도 심재층(20)의 변형이 방지되어 샌드위치 판넬에 대한 공극발생이 최소화되면서도 화재시 화재 전파가 억제되는 튼튼한 건축물 구조를 구현할 수 있게 된다.Also, since the core material layer 20, which is inorganic fiber having good heat resistance, is provided inside the core material, deformation of the core material layer 20 is prevented even if a slight shrinking action is generated in the sandwich panel due to high temperature to minimize the occurrence of voids in the sandwich panel It is possible to realize a robust building structure in which fire propagation is suppressed in case of fire.

그리고 상기 단열재층(10)과 심재층(20)의 두께비율은 1 : 0.4 ~ 0.65 : 1로 이루어짐이 바람직하며, 상기 두께비율 범위에서 심재층(20)은 적어도 하나 이상으로 이루어짐이 바람직하다.The thickness ratio of the heat insulating material layer 10 and the core material layer 20 is preferably 1: 0.4-0.65: 1, and the core material layer 20 is preferably at least one.

이는 상기 두께비율로 단열재층(10)과 심재층(20)이 형성되었을 때 단열재층(10)의 단열효율과 심재층(20)의 흡음효율이 극대화되면서, 심재층(20)이 다수로 적층되었을 때 흡음효율이 좋아지기 때문이다.This is because the heat insulation efficiency of the heat insulating material layer 10 and the sound absorbing efficiency of the core material layer 20 are maximized when the heat insulating material layer 10 and the core material layer 20 are formed at the above thickness ratio, The sound absorption efficiency is improved.

한편, 단열재층(10)과 심재층(20)의 흡음판(23)과 더불어 다수로 적층되는 심재층(20)은 각각 바인더에 의해 접착된다.On the other hand, the heat-insulating layer 10 and the core layer 20, which are laminated in many layers together with the sound-absorbing plate 23 of the core layer 20, are each bonded by a binder.

상기 바인더는 아크릴계 바인더 30 ~ 45중량%, 벤토나이트용액은 30 ~ 45중량%, 난연제 10 ~ 15중량%, 불소발수제 5 ~ 8중량%, 안티몬 2 ~ 5중량% 및 황산바륨 1 ~ 3중량% 로 이루어진다.Wherein the binder comprises 30 to 45 wt% of an acrylic binder, 30 to 45 wt% of a bentonite solution, 10 to 15 wt% of a flame retardant, 5 to 8 wt% of a fluorine-containing water repellent, 2 to 5 wt% of antimony, and 1 to 3 wt% .

상기 바인더의 구성요소에 대해 살펴보면, 아크릴계 바인더는 통상적으로 합성수지를 접착할 때 가장 많이 사용되는 접착제로 사용되며, 아크릴계 바인더가 상기 범위로 혼합될 때 후술되는 바인더의 구성요소들이 혼합되어도 바인더로서 접착기능은 유지할 수 있게 된다.As for the components of the binder, the acrylic binder is generally used as an adhesive most commonly used for bonding synthetic resin, and when the acrylic binder is mixed in the above range, even when the components of the binder described below are mixed, Can be maintained.

또한 심재층(20)의 재질은 무기섬유로 이루어지기 때문에 보다 안정된 강도까지 구비할 수 있게 되는 것이다.Further, since the material of the core layer 20 is made of inorganic fibers, it is possible to provide a more stable strength.

벤토나이트용액은 벤토나이트와 물이 혼합되어 이루어진 것으로 벤토나이트가 가지는 특유의 다른 물질과 혼합하여 다른 물질을 화학적으로 영향을 주지 않으면서 서로 점결시키는 성질로 인해 접착력이 향상될 수 있게 되는 것이다.The bentonite solution is a mixture of bentonite and water, and can be mixed with other unique materials of the bentonite so that the adhesive strength of the bentonite can be improved due to the property of gluing the other materials without chemically affecting them.

난연제는 바인더를 이루는 성분들 중 기체상에서 연소될 수 있는 물질들의 농도를 희석시켜 주게 되어 화재발생을 최소화하면서도 연소시에는 연기의 방출량을 현저히 감소시켜 화재발생에 의한 피해를 줄여준다 또한 고열 또는 고온에도 충분한 접착력을 발휘할 수가 있게 한다.The flame retardant dilutes the concentration of materials that can burn on the gas among the constituents of the binder, thereby minimizing the occurrence of the fire, while significantly reducing the amount of smoke released during the combustion, thereby reducing the damage caused by the fire. So that sufficient adhesive force can be exerted.

불소발수제는 바인더의 발수성능을 부여하여 지면에서 발생되는 냉기 및 외부 온도차이로 의하여 발생되는 응결수에 의한 수분을 방수하여 상시 높은 단열성능을 유지할 수가 있도록 하는 것이다.The fluorine water repellent agent imparts the water repellency of the binder to water, thereby watering the condensation water generated by the difference between the cold air generated from the ground and the external temperature to maintain high heat insulation performance at all times.

안티몬은 방염제의 기능을 구비하는 것으로 난연제와 더불어 샌드위치 판넬용 심재의 화재에 대한 피해를 최소화하도록 한다.Antimony has the function of flame retardant and minimizes the damage to fire of sandwich panel core together with flame retardant.

여기서 상기 바인더 100중량부를 기준으로 황토, 토르마린, 옥, 숯으로 이루어진 군에서 선택된 1종 또는 2종 이상 혼용되어 이루어진 원재료가 20 ~ 30㎚로 분쇄가공되는 친환경물질 3 ~ 5중량부와, 황산바륨 3 ~ 5중량부가 혼합된다.3 to 5 parts by weight of an eco-friendly material in which a raw material mixed with at least one selected from the group consisting of loess, tourmaline, jade and charcoal is pulverized to 20 to 30 nm based on 100 parts by weight of the binder, 3 to 5 parts by weight are mixed.

상기 친환경물질은 음이온이 발생되는 성분들로서 샌드위치 판넬용 심재로 사용될 때 인체에 유익한 음이온이 방출되어 항균, 항습 등의 효과를 도모할 수 있게 되는 것이다.When the eco-friendly material is used as a core material for a sandwich panel as an anion-generating component, an anion beneficial to the human body is released, thereby achieving effects such as antibacterial and humidity.

또한 황산바륨은 바인더를 이루는 구성요소들과 친환경물질을 혼합할 때에 침강이나 층분리 현상이 일어나지 않고 골고루 분산 시키기 위한 침강 방지겸 분산제 역할을 하게 되는 것이다.Also, barium sulphate serves as a sedimentation preventing and dispersing agent for dispersing evenly the components constituting the binder and the environment-friendly substance without sedimentation or layer separation.

상기 단열재층(10)과 심재층(20)의 외면에는 물 40 ~ 45중량%와, 질석, 세라믹, 펄라이트, 황토, 점토로 이루어진 군에서 선택된 1종 또는 2종 이상 혼용되어 이루어진 분말가루 40 ~ 45중량%와, 아크릴 수지 5 ~ 10중량%와, 실란커플링제 5 ~ 10중량%로 이루어지는 코팅제가 도포된다.The outer surface of the heat insulating material layer 10 and the core material layer 20 may contain 40 to 45 wt% of water and 40 to 45 wt% of powdery powder mixed with one or more kinds selected from the group consisting of vermiculite, ceramics, pearlite, , 5 to 10% by weight of an acrylic resin, and 5 to 10% by weight of a silane coupling agent.
