Description
본 발명은 가구용 목재 보드 및 그 제조방법에 관한 것으로서, 보다 구체적으로는 고경도를 가지며, 방수 성능이 우수하고 접착력이 우수하여 장기간 사용에도 들뜨거나 벗겨지지 않으며, 폼알데하이드 및 휘발성 유기화합물 방출이 저감되는 등, 인체에 무해한 환경 목재 보드 및 그 제조방법에 관한 것이다.More particularly, the present invention relates to a wood board for furniture and a method of manufacturing the same, and more particularly, to a wood board for furniture and a method of manufacturing the wood board, And an environmental wood board harmless to the human body, and a manufacturing method thereof.
근래에 들어서는 소비자들의 생활수준이 향상됨에 따라 건축 내장재 대하여 단순한 마감재의 기능 외에 쾌적한 주거환경과 성능을 요구하게 되었고, 제품의 가격도 저렴하면서 품질이 좋은 제품을 선호하게 되었다.In recent years, as the living standards of consumers have improved, besides the function of a simple finish material for a building interior material, a pleasant living environment and performance have been demanded.
일반적으로 건축용 또는 가구용에 사용되고 있는 목재로는 원목(천연목재)과 MDF, PB, 집성목 등과 같은 합성목의 소재가 주로 사용되고 있다.Wood, which is generally used for building or furniture, is mainly made of wood (natural wood), synthetic wood such as MDF, PB, and gypsum.
통상적으로 건축용 또는 가구용 목재의 표면처리 방법에 있어서는 MDF, PB등 목재의 표면에 LPM 이나 HPM 시트를 부착하거나, 열전사필름을 접착시키거나, 목재 표면에 직접 코팅층을 형성하는 방법이 있다.Conventionally, in the method of surface treatment of wood for architectural use or furniture, there is a method of attaching LPM or HPM sheet to the surface of wood such as MDF or PB, adhering a thermal transfer film, or forming a coating layer directly on the wood surface.
LPM 이나 HPM 시트를 부착하는 공정에 있어서, MDF 및 PB의 경우, 목재를 가공하여 재단한 후 목재의 표면에 요소수지 또는 멜라민 수지를 도포한 후 진공상태에서 120~150도의 열로 LPM 이나 HPM 시트를 MDF 및 PB의 표면에 부착시키는 방법을 사용하고 있다.In the process of attaching LPM or HPM sheet, in the case of MDF and PB, after cutting the wood, it is coated with urea resin or melamine resin on the surface of the wood, and LPM or HPM sheet MDF, and PB.
또한 열전사필름을 목재의 표면에 접착시키는 공정에 있어서 MDF 및 PB의 경우, 목재를 가공하여 재단한 후 목재의 표면에 열전사필름이 잘 접착하도록 사포로 MDF 표면에 기스를 내어 본드를 스프레이 방식으로 도포 후 건조 시켜 열전사필름으로 목재의 표면과 옆면을 덮어 요소수지 또는 멜라민 수지를 도포한 후 진공상태에서 120~150도의 열로 LPM 이나 HPM 시트를 열전사필름을 압착시켜 MDF 및 PB의 표면에 부착시키는 방법을 사용하고 있다.In the process of bonding the thermal transfer film to the surface of the wood, in the case of MDF and PB, after the wood is cut and cut, the wood is dipped in the MDF surface with a cloth so that the thermal transfer film adheres well to the surface of the wood, And then dried and coated with a thermal transfer film to cover the surface and side of the wood, then apply urea resin or melamine resin, press LPM or HPM sheet in vacuum at 120 ~ 150 degree to press the thermal transfer film, And the like.
또한, 열전사필름을 목재의 표면에 접착시키는 공정에 있어서 원목과 집성목의 경우, 목재를 가공하여 재단한 후 목재의 표면에 열전사필름이 잘 접착되도록 사포로 목재의 표면에 기스를 내어 열전사필름 잉크의 색과 유사한 안료를 스프레이 도포방식으로 도포, 건조한 후 목재 표면의 눈매를 핸드코드를 이용하여 매운 다음 본드를 스프레이 도포 방식으로 도포 후 건조 시켜 열전사필름으로 표면과 옆면을 덮어 진공상태에서 120~140도의 열로 약 2분간 열전사필름을 압착시켜 목재의 표면과 옆면에 잉크를 전이시킨 후 열전사필름을 떼어내어 하도, 상도로 마감처리를 하고 있다.In addition, in the process of bonding the thermal transfer film to the surface of the wood, in the case of the wood and the glued wood, after the wood is cut and cut, the heat is transferred to the surface of the wood, After spraying and drying the pigment similar to the color of the film ink, the eye of the wood surface is spun using a hand cord, and then the bond is applied by spray coating method and dried, and the surface and the side surface are covered with the thermal transfer film, The thermal transfer film is pressed for about 2 minutes with heat of 120 ~ 140 degrees to transfer the ink to the surface and the side of the wood, and then the thermal transfer film is peeled off to finish with the upper and lower surfaces.
한편, 목재 표면에 직접 코팅층을 형성하는 방법은 대한민국 등록특허 제10-1506344호에 개시되어 있는데, 구체적으로 폴리올 100중량부와, 아크릴 모노머 10~30중량부와, 이소시아네이트 50~100중량부를 혼합하여 이루어지는 바인더를 마련하는 S1단계와; 상기 바인더에 몬모릴로나이트, 일라이트, 게르마늄 및 벤토나이트 중에서 적어도 하나를 포함하는 다공성 무기 분말 5~20중량부를 혼합하여 이루어지는 코팅액을 마련하는 S2단계와; 상기 코팅액을 이용하여 MDF(Medium density fiberboard) 또는 PB(Paticle board)로 이루어지는 목재보드 상에 코팅층을 형성하는 S3단계;를 포함하며, 상기 코팅액에는 적어도 2종 성분이 혼합된 나노 광촉매 0.01~1중량부와 나노 은 0.01~1중량부를 더 포함하되, 상기 나노 광촉매는 TiO2 및 WO3 가 1 : 1.2의 중량비로 혼합되어 가시광 영역의 광에너지가 공급되는 환경에서 광촉매 활성을 가지도록 구성되는 것을 특징으로 하는 친환경 목재보드 제조방법이 개시되어 있다.On the other hand, a method of forming a coating layer directly on the surface of wood is disclosed in Korean Patent No. 10-1506344.
