디자인시트가 부착된 불연 무기질 보드 및 그 제조방법{Noninflammable Inorganic Board integrated with Design Sheet and Manufacturing method thereof}Non-flammable inorganic board with a design sheet and its manufacturing method {Noninflammable Inorganic Board integrated with Design Sheet and Manufacturing method thereof}

본 발명은 디자인시트가 부착된 불연 무기질 보드 및 그 제조방법에 관한 것으로, 보다 상세하게는 무기질 보드와 디자인시트를 무기바인더를 이용하여 접착함으로써 친환경적이며, 무기바인더를 이용해 접착시 고온 건조에 의해 무기질 보드가 변형되는 문제와 약한 접착력을 해결할 수 있는, 디자인시트가 부착된 불연 무기질 보드 및 그 제조방법에 관한 것이다.The present invention relates to a non-combustible inorganic board with a design sheet and a method for manufacturing the same, and more specifically, it is eco-friendly by adhering the inorganic board and the design sheet using an inorganic binder, and is inorganic by high temperature drying when bonding using an inorganic binder. It relates to a non-combustible inorganic board with a design sheet and a method of manufacturing the same, which can solve the problem of deformation and weak adhesion of the board.

최근 들어, 생활이 윤택해지고 풍족해짐에 따라 실내 인테리어에 많은 관심을 갖게 되면서, 초기에는 질감 및 미감이 우수한 천연목재인 고급원목이 각광을 받았으나, 원목의 경우에는 그 형태가 각양 각색으로 다양하고 크기에 한계가 있어 판재로의 가공성이 상당히 어려워 판재의 크기가 제한되는 한계가 있으며, 또한 그 가격이 일반적으로 고가이어서 고가의 고급 가구나 건축내장재 이외에 범용으로 널리 적용시켜 사용하기에는 상당한 경제적 부담이 발생하는 단점이 있었다.In recent years, as life has become richer and richer, as interest in indoor interiors has increased, initially, high-quality wood, which is a natural wood with excellent texture and aesthetics, has been spotlighted, but in the case of wood, its shape varies in various colors and sizes. There is a limitation in that the size of the plate is limited because it is difficult to process into a plate, and the price is generally expensive.Therefore, it has a considerable economic burden to be widely used in general use in addition to expensive high-end furniture and interior materials. There was.

이러한 원목의 단점을 감안하여 비교적 염가로 되는 재료로서는 통상적으로 중밀도 섬유판(Medium-Density Fiberboard, MDF), 합판, 석고보드 등과 같은 인조목이나 합성목을 가구용 판재나 건축용 내장판재로 널리 사용하고 있으며, 이러한 MDF, 합판, 석고보드 등의 내장판재를 표면 처리함에 있어서는 대체로 표면에 폴리염화비닐(polyvinyl chloride, PVC) 필름을 접착하거나 일반 도료로 페인팅하는 방법, 또는 열전사필름을 이용하여 표면에 열 접착시켜 표면을 무늬와 색상을 형성하는 방법 등으로 처리된 판재를 사용하고 있음도 널리 알려져 있다.In consideration of the shortcomings of such wood, artificial wood or synthetic wood such as medium-density fiberboard (MDF), plywood, gypsum board, etc. are generally widely used as materials that are relatively inexpensive. , In the case of surface treatment of interior boards such as MDF, plywood, gypsum board, etc., a film of polyvinyl chloride (PVC) is generally adhered to the surface or painted with a general coating, or heat is applied to the surface using a thermal transfer film. It is also widely known that plate materials treated by bonding to form surfaces and patterns are used.

그러나 MDF나 합판으로 구성한 판재의 경우에 있어서는 그 자체의 물성 상 난연성을 전혀 기대할 수 없기 때문에 화재발생시 쉽게 화염이 옮겨 붙어 화재사고가 대형화되는 문제점이 있을 뿐만 아니라, 이들의 재질 구성의 특성이나 표면에 부착되는 PVC 등의 필름 등에 의하여 연소될 때, 연기와 유독가스를 대량으로 발생시켜 화재 발생시 인명에 치명적인 피해를 가하게 되는 등의 문제점을 나타내고 있다.However, in the case of a plate made of MDF or plywood, since the flame retardance cannot be expected at all due to its physical properties, there is a problem that a fire is easily transferred and a fire accident is enlarged when a fire occurs, as well as the characteristics or surface of the material composition. When it is burned by a film such as attached PVC, it generates a large amount of smoke and toxic gases, causing a fatal damage to humans in the event of a fire.

그리고 석고보드는 그 자체의 물성상 경성(硬性)이어서 인장력이 약하고, 유연성이 전혀 없어 외부 충격에 취약하여, 가공이나 시공시의 절단작업 또는 못질 등에 의한 충격이 가해지는 경우 표면이 쉽게 파손되는 단점을 지니고 있어 가공이나 시공에 상당한 어려움이 뒤따르는 등의 문제점이 있다.In addition, the gypsum board has its own physical properties, so it has a weak tensile force and is not susceptible to external shocks because it has no flexibility, and the surface is easily damaged when an impact is caused by cutting or nailing during processing or construction. It has problems such as significant difficulties in processing or construction.

이를 해결하고자, 난연성과, 유연성 및 보온성이 우수하고, 환경친화적인 마그네슘과 같은 무기질 소재로 된 마그네슘 보드가 개발되어, 각종 건물의 내장재 등으로 사용되기도 하였다.To solve this, magnesium boards made of inorganic materials, such as magnesium, which are excellent in flame retardancy, flexibility, and warmth, have been developed, and have been used as interior materials for various buildings.

그러나 이러한 종래 마그네슘 보드에는 다양한 무늬와 형태를 갖는 마감지가 잘 부착되지 않아, 점착성이나, 제품의 균일성 등이 떨어지며, 제품의 고유 형태가 변형되는 등 여러 가지 사용상의 문제점이 발생되었다.However, such conventional magnesium boards do not adhere well to finishes having various patterns and shapes, resulting in poor adhesiveness, product uniformity, etc., and various problems in use such as deformation of the product's original shape.

한편, 마그네슘 보드에 HPM(고압 멜라민 함침지), LPM(저압 멜라민 함침지)을 120 내지 180℃로 가열 접착시키거나, 접착제로 플라스틱류를 사용하여 부착시키면 한 방향으로 휨발생이 발생하여 휘어진 인테리어 자재로 공사에 적용하는데 어려움이 수반되는 2차 문제가 발생할 뿐만 아니라, 인테리어 공사 후 시간이 지남에 따라 계속되는 보드의 수분 흡수성과 기온 편차에서 발생되는 수축 팽창성에 의해 마그네슘 보드의 상면에 부착된 플라스틱 시트의 접착력이 저하되어 박리되는 문제가 발생된다.On the other hand, if the HPM (high pressure melamine impregnated paper) and LPM (low pressure melamine impregnated paper) are adhered to the magnesium board by heating to 120 to 180 ° C, or attached using plastics as an adhesive, bending occurs in one direction, resulting in a curved interior A plastic sheet attached to the upper surface of the magnesium board by not only the secondary problem that is difficult to apply to the construction with materials, but also due to the moisture absorption of the board that continues over time after the interior construction and the shrinkage expansion that occurs in temperature variations. The adhesive strength of the is lowered and the problem of peeling occurs.

대한민국등록특허공보 제10-1459417호(2014.11.07.)에는 마그네슘 보드를 이용한 패널 및 그 제조방법이 개시되어 있다.Korean Patent Registration No. 10-1459417 (2014.11.07.) Discloses a panel using a magnesium board and a manufacturing method thereof.

상기 마그네슘 보드를 이용한 패널 및 그 제조방법은 그라비아 인쇄가 아닌 디지털 인쇄 방식으로 문양, 색상 등의 미적 감각을 부여한 제1 및 제2 디지털 표면재를 적용함으로써, 소비자의 개별 취향에 따라 1장씩 원하는 디자인을 구현하는 방식으로 제조할 수 있으므로 소비자의 욕구를 충족시킬 수 있을 뿐만 아니라 디지털 방식으로 인쇄가 이루어지므로 HPM 방식으로 구현하기 어려운 세부적인 디자인을 구현할 수 있는 장점이 있지만, 마그네슘 보드와 디지털 표면재 사이에 에틸렌비닐아세테이트라는 유기접착제를 사용하기 때문에 최근 강화된 실내공기오염물질에 대한 기준을 만족시키지 못하는 문제가 있다.The panel using the magnesium board and its manufacturing method apply the first and second digital surface materials that give aesthetic sense of patterns, colors, etc. in a digital printing method, not gravure printing, so that the desired design can be selected one by one according to the individual taste of the consumer. Since it can be manufactured in an embodied manner, it not only satisfies the consumer's desire, but also has the advantage of realizing a detailed design that is difficult to implement with the HPM method because it is digitally printed, but ethylene is between the magnesium board and the digital surface material. Since vinyl acetate uses an organic adhesive, there is a problem that it cannot satisfy the recently strengthened standards for indoor air pollutants.

상기 접착층은 상기 무기질 보드와 상기 불연처리된 디자인시트를 접착하는 역할을 수행한다. 상기 접착층은 액상규산칼륨을 사용하는 것이 바람직하다. 상기 접착층에 액상규산나트륨을 사용하는 경우에는 백화현상이 발생하는 문제가 있다. The adhesive layer serves to bond the inorganic board and the non-flammable design sheet. It is preferable to use liquid potassium silicate as the adhesive layer. When liquid sodium silicate is used for the adhesive layer, there is a problem that whitening occurs.

본 발명에 따른 액상규산칼륨은 비중(20℃)이 1.318~1.330인 것이 바람직하고, 비중(20℃)이 1.318 미만이면 접착력이 떨어져 강도가 약해지는 문제가 있고, 비중(20℃)이 1.330 초과이면 끈적거려 보드 표면에 도포하기 어려운 문제가 있다.The liquid potassium silicate according to the present invention preferably has a specific gravity (20 ° C) of 1.318 to 1.330, and if the specific gravity (20 ° C) is less than 1.318, there is a problem that the strength of the adhesive falls and the specific gravity (20 ° C) exceeds 1.330. There is a problem that the back side is sticky and difficult to apply to the surface of the board.

액상규산칼륨의 몰비 계산은 다음과 같다.The molar ratio calculation of liquid potassium silicate is as follows.

규산칼륨의 몰비 = (SiO2/K2O)의 중량비 × 1.568Molar ratio of potassium silicate = weight ratio of (SiO 2 / K 2 O) × 1.568

본 발명에 따른 액상규산칼륨은 SiO2 대 K2O의 몰비가 3.5~3.7인 것이 바람직하고, SiO2 대 K2O의 몰비가 3.5 미만이면 접착력이 떨어지는 문제가 있고, SiO2 대 K2O의 몰비가 3.7 초과이면 끈적거려 보드 표면에 도포하기 어려운 문제가 있다.In the liquid potassium silicate according to the present invention, the molar ratio of SiO 2 to K 2 O is preferably 3.5 to 3.7, and when the molar ratio of SiO 2 to K 2 O is less than 3.5, there is a problem of poor adhesion, and SiO 2 to K 2 O If the molar ratio of is more than 3.7, there is a problem that it is sticky and difficult to apply to the board surface.

상기 접착층의 두께가 0.1㎜미만이면 접착력이 떨어지는 문제가 있고, 접착층의 두께가 0.3㎜초과이면 건조 시간이 오래 걸리고 표면이 매끈하지 않거나 깔끔하지 않게 되는 문제가 있다.If the thickness of the adhesive layer is less than 0.1 mm, there is a problem of poor adhesion, and if the thickness of the adhesive layer exceeds 0.3 mm, it takes a long time to dry and there is a problem that the surface is not smooth or neat.

상기 접착층에 접착되는 불연처리된 디자인시트는 원하는 색상 및 무늬를 디자인한 합성수지, 부직포, 종이 또는 섬유를 사용할 수 있으며, 이에 한정되지 아니한다.The non-flammable design sheet adhered to the adhesive layer may use synthetic resin, non-woven fabric, paper or fiber designed with desired colors and patterns, but is not limited thereto.

상기 불연처리된 디자인시트는 디자인시트를 액상규산칼륨이 담겨있는 탱크에 함침처리하는 것을 의미한다. 상기 탱크에 담겨있는 액상규산칼륨은 상기 접착층에서 사용하는 액상규산칼륨과 동일한 것을 사용할 수 있다. The non-flammable design sheet means that the design sheet is impregnated into a tank containing liquid potassium silicate. The liquid potassium silicate contained in the tank may be the same as the liquid potassium silicate used in the adhesive layer.

상기 함침처리시 탱크에 담겨있는 액상규산칼륨의 온도는 30~40℃인 것이 바람직하다. 탱크에 담겨있는 액상규산칼륨의 온도가 30℃ 미만이면 디자인시트의 불연처리가 미흡한 문제가 있고, 탱크에 담겨있는 액상규산칼륨의 온도가 40℃ 초과이면 상태가 묽어져서 불연처리가 미흡한 문제가 있다.The temperature of the liquid potassium silicate contained in the tank during the impregnation treatment is preferably 30-40 ° C. When the temperature of the liquid potassium silicate contained in the tank is less than 30 ° C, there is a problem that the nonflammable treatment of the design sheet is insufficient, and when the temperature of the liquid potassium silicate contained in the tank exceeds 40 ° C, the state is dilute and there is a problem that the nonflammable treatment is insufficient. .
