본 발명은 가구용 표면재인 데코시트의 표면을 보호하기위해 부착되는 데코시트 보호필름 및 그 제조방법에 관한 것으로,The present invention relates to a decorative sheet protective film attached to protect the surface of a decorative sheet, which is a surface material for furniture, and a manufacturing method thereof,
표면에 PU(Polyurethane)가 인쇄된 데코시트 PU(Polyurethane)의 상부에, PU(Polyurethane) 2액형 도료를 2회 이상 코팅하고 건조로에서 건조 후 권취하되, On the upper part of the decorative sheet PU (Polyurethane) with PU (Polyurethane) printed on the surface, coat PU (Polyurethane) two-component paint more than twice, dry in a drying furnace, and then wind up,
상기 PU(Polyurethane) 2액형 코팅공정 사이에는 내부에 액을 포함하지않은 건조조를 통과하며, 권취 후 바로 점착제를 도포하지않고 밀폐공간에서 고온숙성 후 점착제를 도포함으로써, 내열성 및 내구성이 개선된 데코시트 보호필름 및 그 제조방법에 관한 것이다.Between the PU (Polyurethane) two-component coating process, it passes through a drying tank that does not contain liquid inside, and by applying the adhesive after aging at a high temperature in an enclosed space instead of applying the adhesive immediately after winding, it is a decor with improved heat resistance and durability. It relates to a sheet protective film and a manufacturing method thereof.
일반적으로 가구 및 건축 내장재로는, 값비싼 원목 대신에 합판, 중밀도섬유판(MDF), 하드보드(hardboard), 파티클보드(particle board) 등의 목질계 기초재 또는 기타 각종 재질의 재료가 사용되는데, 이러한 재료는 그 표면의 거칠기, 강도 및 미감이 좋지 않아, 표면 보호, 모양 부여, 전도성 및 난연성 등과 같은 특정의 기능을 부여할 수 있도록, 종이 또는 합성수지재 등 다양한 종류의 데코시트가 사용된다.In general, for furniture and building interior materials, wood-based base materials such as plywood, medium-density fiberboard (MDF), hardboard, and particle board or other various materials are used instead of expensive hardwood. , These materials have poor surface roughness, strength and aesthetics, so various types of decorative sheets such as paper or synthetic resin materials are used to give specific functions such as surface protection, shape, conductivity and flame retardancy.
가구 및 건축 내장재로 사용되는 데코시트는, HPL(high pressure laminate), LPL(low pressure laminate), LPM(low pressure melamine), PVC(polyvinylchloride), PC(polycarbonate) 등의 마감 포일(finishing foil)이 주로 사용되는데, 상기 데코시트는 이동 또는 보관 중 표면이 손상될 수 있으므로 그 표면에 데코시트 보호필름을 부착하여 사용한다.Decorative sheets used as furniture and interior materials for construction include finishing foils such as HPL (high pressure laminate), LPL (low pressure laminate), LPM (low pressure melamine), PVC (polyvinylchloride), and PC (polycarbonate). It is mainly used, since the surface of the decorative sheet may be damaged during movement or storage, it is used by attaching a decorative sheet protective film to the surface.
가구 및 건축 내장재로 사용되는 데코시트는 표면에 나무무늬 등 다양한 모양이 인쇄되고 그 상부에는 인쇄면을 보호하기 위한 코팅층이 형성될 수 있으며,Decor sheets used as furniture and building interior materials may have various patterns such as wood patterns printed on the surface, and a coating layer to protect the printed surface may be formed on the top.
이와 같이 구성된 데코시트의 표면에 상기 데코시트 보호필름이 부착되어 사용되는 것이다.The decorative sheet protective film is attached to the surface of the decorative sheet configured as described above.
도 4는 종래기술에 따른 데코시트 보호필름의 단면도로서,Figure 4 is a cross-sectional view of a decorative sheet protective film according to the prior art,
종래의 데코시트 보호필름은 PE(Polyethylene) 또는 PU(Polyurethane)재질로 구성되며, PE(Polyethylene) 또는 PU(Polyurethane)재질로 된 필름(1)이 PU(Polyurethane) 코팅액조의 코팅롤러를 통과하는 동안, 상기 필름(101) 표면에 PU(Polyurethane) 코팅층(103)이 도포되고, 건조로를 통과하는 동안 상기 PU(Polyurethane)은 완전건조되며, 권취롤러에서 권취된 후 점착제 도포 공정을 진행하여 상기 필름(101) 저면에 점착제층(102)이 형성되는 것이다.The conventional decorative sheet protective film is composed of PE (Polyethylene) or PU (Polyurethane) material, while the film (1) made of PE (Polyethylene) or PU (Polyurethane) material passes through the coating roller of the PU (Polyurethane) coating bath. , A PU (Polyurethane)
그런데 이와 같이 형성된 종래의 데코시트 보호필름은, 저온에서는 별 문제가 발생되지않았지만 고온에 취약한 문제점이 발생되었다.However, the conventional decorative sheet protective film formed in this way did not cause any problems at low temperatures, but was vulnerable to high temperatures.
예를 들어, 데코시트 보호필름의 표면에 매직잉크로 표시한 경우 저온에서는 별 문제가 발생되지않았지만, 장거리 수송을 위해 컨테이너에 보관하거나 열대기온에 노출될 시에는 매직잉크가 상기 데코시트 보호필름을 투과하여 데코시트에 전사되므로, 데코시트가 손상되는 문제점이 발생한다.For example, if the surface of the decorative sheet protective film is marked with magic ink, there is no problem at low temperatures, but when stored in a container for long-distance transportation or exposed to tropical temperatures, the magic ink degrades the decorative sheet protective film. Since it penetrates and is transferred to the decorative sheet, a problem in that the decorative sheet is damaged occurs.
이러한 데코시트의 손상은 고객의 클레임을 동반하므로, 경제적 손실이 발생하고 제품의 신뢰도 및 브랜드 이미지를 실추시키는 문제점이 있었다.Since the damage to the decorative sheet is accompanied by a customer's claim, there is a problem in that economic loss occurs and the reliability and brand image of the product is lost.
