Description
본 발명은 건축물에 사용되는 샌드위치 판넬용 심재 및 그 제조방법에 관한 것으로서, 특히 상, 하측으로 각각 단열재층이 형성되고, 상기 단열재층 사이로 흡음층과 골판지층이 각각 형성되는 샌드위치 판넬용 심재 및 그 제조방법에 관한 것이다.The present invention relates to a core material for a sandwich panel used in a building and a method of manufacturing the same. More particularly, the present invention relates to a core material for a sandwich panel in which a heat insulating material layer is formed on each of upper and lower sides, And a manufacturing method thereof.
일반적으로, 샌드위치 판넬은 강판과 강판 사이에 심재를 넣어 접착 또는 발포시켜 만들어지는데, 이때 사용되는 심재는 단열성이 뛰어난 재질을 사용하며, 이는 비교적 가볍고 단열이 우수하기 때문에 건축물 판넬 등에 많이 사용되고 있다.Generally, a sandwich panel is made by sticking a core material between a steel sheet and a steel sheet and bonding or foaming the core material. The core material used in this case is made of a material having excellent heat insulation property, which is relatively light and excellent in heat insulation.
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 질식사 등의 우려가 높고, 가연성이 높아 대형 화재로 발전될 가능성이 높아 점차적으로 그 활용성이 떨어지고 있다.The polyurethane foam and the styrofoam are excellent in the heat insulation property. However, due to the combustion characteristic of the organic material, a large amount of noxious gas is generated when a fire occurs, so that the risk of suffocation It is highly likely to develop into a large fire due to its high flammability, and 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 조절하는 별도의 공정을 야기시키게 되고, 그리고 대형 화재의 발생을 줄이기 위해 가연성이 높은 폴리우레탄폼, 스치로폼에 난연제를 도포하여 사용하여 왔다.However, in order to have the sound absorbing property of the core material, a separate process of controlling the compressive strength is caused, and a flame retardant is applied to polyurethane foam and styrofoam having high flammability in order to reduce occurrence of a large fire.
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.
본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, 상, 하측으로 각각 단열재층이 형성되고, 상기 단열재층 사이로 다수의 벌집 형태의 구조를 가진 흡음층과 골판지층이 각각 구비되어 단열기능뿐만 아니라 흡음층과 골판지층의 진동에 의해 흡음층과 골판지층에 통과된 음파를 흡음시켜 흡음효율이 향상되는 샌드위치 판넬용 심재 및 그 제조방법을 제공하는데 그 목적이 있다.Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a sound insulating layer and a corrugated cardboard layer, And it is an object of the present invention to provide a core material for a sandwich panel which is improved in sound absorption efficiency by absorbing sound waves passed through a sound-absorbing layer and a corrugated cardboard layer by vibration of a sound-absorbing layer and a corrugated cardboard layer.
또한 단열재층과 흡음층과 골판지층을 접착하는 바인더로 하여금 난연기능이 강화되면서 접착강도가 향상되는 샌드위치 판넬용 심재 및 그 제조방법을 제공하는데 또 다른 목적이 있다.Another object of the present invention is to provide a core material for a sandwich panel in which a binder for bonding a heat insulating material layer, a sound-absorbing layer and a corrugated cardboard layer to each other is improved in flame retardancy and adhesive strength, and a method for producing the same.
상기와 같은 목적을 실현하기 위하여 본 발명은, 강판과 강판 사이에 구비되는 샌드위치 판넬용 심재에 있어서, 상, 하측으로 각각 EPS패널인 단열재층; 상기 단열재층 사이로 벌집 형태가 다수로 배열되고, 재질은 종이 또는 부직포인 흡음층; 상기 단열재층과 흡음층 사이에 파형으로 연장되는 심지와, 상기 심지의 양측에 구비되는 판지로 이루어져 심지와 판지로 인해 공기부가 형성되며, 재질은 종이 또는 부직포인 골판지층;이 포함되는 샌드위치 판넬용 심재를 제공한다.In order to achieve the above object, the present invention provides a core material for a sandwich panel provided between a steel sheet and a steel sheet, comprising: a heat insulating material layer as an EPS panel on upper and lower sides; A plurality of honeycomb shapes are arranged between the heat insulating material layers, and the material is a paper or non-woven fabric; And a corrugated cardboard layer formed of a cardboard provided on both sides of the core and extending from corrugations between the heat insulating material layer and the sound-absorbing layer, and air formed by corrugation and cardboard, and made of paper or a nonwoven fabric.

여기서 도 3에 도시된 바와 같이 상기 흡음층(20)를 이루는 각 면마다 통공(21)이 다수 형성된다.Here, as shown in FIG. 3, a plurality of through

한편, 단열재층(10)과 흡음층(20)과 골판지층(30)은 각각 바인더에 의해 접착된다.On the other hand, the heat insulating
상기 바인더는 아크릴계 바인더 30 ~ 45중량%, 벤토나이트용액은 30 ~ 45중량%, 난연제 10 ~ 15중량%, 불소발수제 5 ~ 8중량%, 안티몬 2 ~ 5중량%로 이루어진다.The binder comprises 30 to 45% by weight of an acrylic binder, 30 to 45% by weight of a bentonite solution, 10 to 15% by weight of a flame retardant, 5 to 8% by weight of a fluorine-containing water repellent, and 2 to 5% by weight of antimony.
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 흡음층(20)과 골판지층(30)의 재질은 종이 또는 부직포로 이루어지기 때문에 보다 안정된 강도까지 구비할 수 있게 되는 것이다.In addition, since the sound-absorbing
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.

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 코팅제의 분말가루는 인체에 무해한 난연제 기능을 수행하며, 아크릴 수지와 더불어 단열기능을 수행할 수 있도록 한다.The powder of the coating agent functions as a flame retardant harmless to the human body and can perform an insulating function in addition to the acrylic resin.
또한 실란커플링제는 바인더의 접착력 및 점성을 향상시켜 코팅제의 분말가루와 접착력을 좋게 하고 우수한 접착강도를 구비하여 코팅공정이 효율적으로 이루어져 생산성을 향상시키게 한다.In addition, the silane coupling agent improves the adhesive force and viscosity of the binder, improves the adhesive force with the powder of the coating agent, and has an excellent bonding strength, thereby improving the productivity by efficiently performing the coating process.
