Description

난연성 기능을 갖는 마루판{floor board to prevent burning}Floorboard with flame retardant function {floor board to prevent burning}

본 고안은 난연성 기능을 갖는 마루판에 관한 것으로, 특히 난연성 처리가 된 메라핀화장판과 바란스시이트를 판재에 접착시켜 화재의 위험으로부터 보호해주는 난연성 기능을 갖는 마루판에 관한 것이다.The present invention relates to a floorboard having a flame retardant function, and more particularly to a floorboard having a flame retardant function to protect the risk of fire by adhering the flame retardant treatment meparin cosmetic plate and the balance sheet to the plate.

첨부한 도1은 종래의 마루판재의 일예를 도시한 것으로, 이에 도시한 마루판재는 내수 합판(1)의 상면에 0.3~0.6mm 정도 두께를 가진 무늬목(2)을 접착시킨 후 표면에 도장처리를 하여 제조한 것이며, 열 및 습기에 대한 치수 안정성이 우수한 반면 표면이 얇은 무늬목(2)으로 처리되어 있기 때문에 표면 강도가 약하여 충격에 의한 찍힘이나 긁힘이 생기기 쉽고, 가연성 물질로 구성되어 있을 뿐 아니라 내화학성 및 내오염성이 약한 문제점이 있었다.Figure 1 shows an example of a conventional floorboard material, the floorboard material shown therein is coated on the surface after the veneer (2) having a thickness of about 0.3 ~ 0.6mm on the upper surface of the water-resistant plywood (1) It is manufactured by using the product, and it has excellent dimensional stability against heat and moisture, but because the surface is treated with thin veneer (2), its surface strength is weak, so that it is easy to cause scratches or scratches due to impact, and is not composed of combustible materials. There was a weak chemical resistance and fouling resistance.

따라서, 흔히 마루판은 도2에 도시한 바와 같이, 내수 합판(3)의 상면에 0.6mm 정도의 비난연성 메라민화장판(4)을 접착시키고 내수 합판(3)의 하면에는 바란스시이트(5)를 접착시킨 구조로 제조되며, 이와 같은 마루판은 상면에 부착된 메라민화장판(4)이 HPL(high pressure melamine laminate)로 구성되어 있으므로 표면물성이 뛰어나고, 내수 합판(3)의 사용으로 인해 습기에 의한 변형이 적은 것이 장점이다.Therefore, the floorboard is often bonded to the non-flammable melamine cosmetic board 4 of about 0.6mm on the upper surface of the water-resistant plywood 3, as shown in Figure 2 and the balance sheet (5) on the lower surface of the water-resistant plywood (3) It is manufactured in a bonded structure, and such a floorboard is excellent in surface properties because the melamine cosmetic board (4) attached to the upper surface is composed of a high pressure melamine laminate (HPL), due to the use of a water-resistant plywood (3) Less deformation is an advantage.

또한, 바닥의 습기에 의한 변형을 차단하기 위해 하면에 처리된 바란스시이트(5)가 습기차단 기능을 갖도록 함으로써 제품의 변형을 줄일 수 있으며, 바란스시이트(5)의 표면은 샌딩처리를 하여 접착력을 향상시키도록 한다.In addition, in order to block deformation caused by moisture on the floor, the balance sheet 5 treated on the lower surface may have a moisture blocking function, thereby reducing deformation of the product, and the surface of the balance sheet 5 is sanded to improve adhesion. Try to improve.

그러나 이와 같은 제품도 난연기능을 갖지 못하므로 바닥에 유류 또는 가연물질에 의해 화재가 발생하면 보호받을 수 없는 문제점이 있었다.However, such a product also does not have a flame retardant function, there was a problem that can not be protected when a fire occurs by oil or flammable material on the floor.

첨부한 도3에 도시한 종래의 마루판은 0.6mm 정도의 비난연처리된 메라민화장판(6)을 MDF, 파티클보드(7)의 상면에 접착시켜 가공한 제품으로써 MDF, 파티클보드(7)의 하면에는 비난연성의 종이 시이트(8)가 접착되어 있다.The conventional floorboard shown in FIG. 3 is a product obtained by attaching a non-flammable and treated melamine cosmetic plate 6 of about 0.6 mm to the upper surface of the MDF and the particle board 7 and processing the MDF and the particle board 7. On the lower surface, a non-flammable paper sheet 8 is bonded.

이와 같은 종래의 제품은 상면에 접착된 메라민화장판(6)으로 HPL를 사용하므로 표면물성은 뛰어난 반면 내수성 및 치수안정성이 불량하며 난연기능이 없으므로 화재시 위험성이 있었다.Such a conventional product uses HPL as the melamine cosmetic plate 6 adhered to the upper surface, so that the surface properties are excellent, while the water resistance and dimensional stability are poor, and there is no flame retardant function.

또한, 도4의 마루판은 0.2mm 정도의 저압메라민 함침적층판(low pressure melamine laminate)(9)을 MDF(10) 상면과 하면에 처리하는 구조로 되어 있으며, 상면에 접착된 저압메라민 함침적층판(9)은 그 표면에 투명보호층(9a)이 처리되어 있으므로 내마모성, 내스크래치형, 내약품성은 우수하나 MDF(10)의 특성상 내수성에 의한 두께 팽창으로 인한 단차이로 벗겨짐 또는 치수변형이 심하게 나타나고 난연기능이 없으므로 화재시 위험한 문제점이 있었다.Further, the floorboard of FIG. 4 has a structure in which a low pressure melamine laminate 9 having a thickness of about 0.2 mm is treated on the upper and lower surfaces of the MDF 10, and the low pressure melamine impregnated laminate 9 adhered to the upper surface. ) Has abrasion resistance, scratch resistance, and chemical resistance because the transparent protective layer 9a is treated on the surface thereof, but due to the characteristics of the MDF 10, peeling or dimensional deformation appears severely due to the difference in thickness due to water resistance. There was no function, so there was a dangerous problem in fire.

따라서, 본 고안은 상술한 바와 같은 종래 마루판들의 문제점을 감안하여 안출한 것으로서, 난연처리된 메라민화장판과 난연처리된 바란스시이트를 각각 별도로 생산하여 내수 합판의 상면과 하면에 각각 접착함으로써, 화재시 마루판의 연소를 막고 인명과 재산의 피해를 줄일 수 있는 난연성 기능을 갖는 마루판을 제공하는데 그 목적이 있다.Therefore, the present invention has been devised in view of the problems of the conventional floorboards as described above, by producing a flame-retardant Meramine cosmetic plate and a flame-retardant varnish sheet separately and bonded to the upper and lower surfaces of the domestic plywood, respectively, in case of fire It is an object of the present invention to provide a floorboard having a flame retardant function that can prevent combustion of floorboards and reduce the damage to life and property.

상기와 같은 목적을 달성하기 위하여 본 고안은 난연첨가제가 함유된 메라민수지를 각각의 시트에 함침시킨 후 고온(130~145℃)고압(50~100㎏/㎠) 프레스로 열경화시켜 제조하는 메라민화장판과, 난연첨가제가 함유된 메라민수지와 페놀수지를 크라프트지에 함침건조한 후 적층하여 고온고압 프레스로 열경화시켜 제조되는 바란스시이트와, 상기 메라민화장판과 바란스시이트 사이에 접착되는 내수 합판으로 구성되는 난연성 기능을 갖는 마루판을 제공한다.In order to achieve the above object, the present invention impregnates the melamine resin containing a flame retardant additive in each sheet, and is then prepared by thermosetting with a high temperature (130-145 ° C.) high pressure (50-100 kg / cm 2) press. It is composed of a varnish sheet, a varnish sheet prepared by impregnating and drying a melamine resin and a phenol resin containing a flame retardant additive in a kraft paper, followed by lamination and thermosetting by a high temperature and high pressure press, and a water-resistant plywood bonded between the melamine cosmetic sheet and the varnish sheet It provides a floorboard having a flame retardant function.
