Description

합판용 장식필름 및 그 제조방법{Decotative film for plywood and manufacturing process thereof} Technical Field [0001] The present invention relates to a decorative film for plywood,

본 발명은 합판용 장식필름 및 그 제조방법에 관한 것으로, 더욱 상세하게는 폴리에틸렌테프탈레이트(PET: Polyethylene terephthalate) 또는 폴리프로필렌(PP: Polypropylene)재 필름의 이면(裏面)에 핫멜트(Hot melt)가 직접 도포되도록 하고, 합판의 표면에 장식필름을 부착할 때 합판에 핫멜트를 도포한 상태에서 장식필름을 부착시키는 것이 아니라, 핫멜트가 도포된 장식필름을 합판의 표면에 밀착시킨 상태에서 가온/가압롤러를 이용하여 열을 가하면서 가압하여 부착시킬 수 있도록 함으로써 합판의 표면에 부착된 장식필름의 수평도가 전체적으로 고르게 유지될 수 있도록 한 합판용 장식필름 및 그 제조방법에 관한 것이다. The present invention relates to a decorative film for a plywood and a method of manufacturing the same. More particularly, the present invention relates to a decorative film for a plywood, and more particularly to a decorative film for a plywood, The decorative film is applied directly to the surface of the plywood, and the decorative film is not adhered to the plywood in a state where the hot melt is applied to the plywood when the decorative film is attached to the surface of the plywood. The present invention relates to a decorative film for a laminating board and a method of manufacturing the decorative film for a laminating board, in which the horizontal degree of a decorative film adhered to the surface of the laminating board can be maintained evenly.

일반적으로, 합판 등의 판재는 건축물의 내부 또는 각종 가구, 도어, 광고재 등에 사용되는 인테리어 소재이다.Generally, a plate material such as a plywood is an interior material used for interior of a building, various furniture, doors, advertising materials, and the like.

이 같은 합판들은 사용되는 분야에 따라 표면에 다양한 무늬를 형성하거나, 빛이 반사될 수 있도록 광택 처리되어 사용되고 있으며, 이를 위하여 합판의 표면에 장식필름을 부착시켜 미려한 장식미가 구현된 인테리어 소재로 사용하고 있다. Such plywoods are used in various patterns formed on the surface according to the field of use or as being polished to reflect the light. For this purpose, a decorative film is attached to the surface of the plywood to use as an interior material having a beautiful decorative effect have.

이러한 장식필름은 재료를 보호하고 외관을 다양한 색상과 질감으로 표현한 마감재를 일컫는 것으로, 특히 실내 인테리어용품 건자재나 가구, 책상 등의 표면을 장식하는 재료로 많이 사용된다.Such decorative film refers to a finishing material which protects the material and expresses the appearance in various colors and textures, and is used as a material for decorating the surface of interior materials, furniture and desks.

이러한 장식필름은 일반적인 도장(塗裝)이나 라미네이팅(Laminating) 방법으로 제조될 수 있는데, 상기 라미네이팅 방법에 의한 필름(Laminating Film)은 접착형과 점착형이 있고, 사용하는 재료에 따라 멜라민 시트(Melamine Sheet)와 종이 그리고 PVC(Poly Vinyl Chloride), PP(Polypropylene) 장식시트로 나눌 수 있다.Such a decorative film can be produced by a general coating method or a laminating method. The laminating film according to the laminating method has an adhesive type and a sticking type. Depending on the material to be used, a melamine sheet Sheet and paper, PVC (Poly Vinyl Chloride) and PP (Polypropylene) decorative sheet.

또한, 최근에는 장식시트 최상층에 폴리에틸렌테레프탈레이트(PET:Polyethylene terephthalate) 또는 폴리프로필렌(PP:Polypropylene) 재질의 투명필름을 부가시킨 장식시트가 많이 사용되고 있는데, 상기 투명필름의 아래에는 그라비아 인쇄 등을 이용하여 인쇄층을 형성하며, 투명필름의 위에는 입체감 등을 부가하기 위하여 엠보싱(Embossing) 처리를 하기도 한다.In recent years, a decorative sheet in which a transparent film made of polyethylene terephthalate (PET) or polypropylene (PP) is added to the topmost layer of a decorative sheet is often used. Gravure printing or the like is used below the transparent film And a embossing process is performed on the transparent film in order to add a three-dimensional effect or the like.

이와 같은 장식시트는 오버레이(OVERLAY)용, 랩핑(WRAPPING)용, 멤브레인(MEMBRANE)용, 단부(EDGE)용 등으로 구분할 수 있으며, 오버레이용은 가구나 건축자재의 중밀도 섬유판(MDF:Medium Density Fiberboard)이나 PB(Particle Board)의 평평한 상부에 일반적으로 사용되고, 랩핑용은 소폭의 샷시나 몰딩부분 등 곡면가공이 필요한 부분에 사용된다. Such a decorative sheet can be classified into an overlay, a wrapping, a membrane, and an edge. The overlay can be divided into a medium density fiberboard (MDF) ) Or PB (Particle Board), and for lapping, it is used for parts requiring a curved surface such as a small sash or molding part.

또한, 멤브레인용은 곡면가공이 많은 일반가구나 문 등에 사용되고, 단부용은 가구나 책상 등의 모서리 부분 또는 상판의 곡면에 사용되며, 근래에는 전자제품이나 기타 금속 철판의 외부에 철판용 장식시트가 사용되고 있다.In addition, the membrane is used for general furniture and doors with many curved surfaces, the end is used for corners of furniture, desk, etc., or curved surfaces of the top plate. Recently, decorative sheets for iron plates have been used outside of electronic products or other metal plates .

상기한 바와 같은 종래의 장식시트는 소재가 다른 경우 소재간의 열융착에 의한 부착이 용이하지 않아 접착제를 이용한 방법을 적용하였다. 하지만 접착제를 적용할 경우 별도의 설비가 요구되며, 가열시 층간 박리가 발생하는 단점이 있다.In the case of the above-mentioned conventional decorative sheet, when the material is different, adhesion by heat fusion between materials is not easy, and a method using an adhesive is applied. However, when an adhesive is applied, a separate facility is required and there is a disadvantage that delamination occurs during heating.

한편, 종래 장식필름을 합판의 표면에 부착시키는 방법을 살펴보면, 도 1에 도시된 바와 같이, 합판(10)의 표면에 접착제인 핫멜트(Hot melt:11)를 녹여 도포하고, 상기 합판(10)의 표면에 도포된 핫멜트(11)의 표면에 장식필름(12)을 부착시키는 것이 일반적이다.1, a hot melt 11 as an adhesive is melted and applied to the surface of the plywood 10, and the plywood 10 is heat- The decorative film 12 is generally adhered to the surface of the hot melt 11 applied to the surface of the hot melt 11.

그러나, 이와 같은 종래의 합판(10)에 대한 장식필름(12)의 부착방식에서는 합판(10)의 표면에 대한 핫멜트(11)의 도포상태가 전체적으로 균일하게 이루어지지 않고 울퉁불퉁하기 때문에 수평도가 유지되지 않아 장식필름의 수평상태 또한 불균일하게 이루어져 품질이 고르지 못하다는 심각한 문제가 있다. However, in the conventional method of attaching the decorative film 12 to the plywood 10, since the application state of the hot melt 11 to the surface of the plywood 10 is not uniform as a whole but is uneven, And the horizontal state of the decorative film is also nonuniform, which is a serious problem that the quality is uneven.

이와 같은 장식필름과 관련된 기술로서, 대한민국 등록실용신안공보 등록번호 제20-0441232호(명칭: 장식시트, 이하 '선행기술"이라 함)가 제안되었다.As a technique related to such a decorative film, Korean Registered Utility Model Registration No. 20-0441232 (name: decorative sheet, hereinafter referred to as "prior art") has been proposed.

상기 선행기술은 '폴리프로필렌, 폴리에틸렌테레프탈레이트 또는 폴리염화비닐로 된 기재 필름에 에틸렌비닐아세테이트 또는 저밀도 폴리에틸렌을 압출코팅하여 코팅층을 형성하여 제조된 투명필름에, 폴리염화비닐, 폴리프로필렌 또는 폴리에틸렌테레프탈레이트로 이루어진 인쇄층을 열합판하여 이루어지는 것'을 그 기술적 구성의 요지로 하는 것이다.The prior art described above is a method in which a transparent film made by extrusion coating ethylene vinyl acetate or low density polyethylene on a base film made of polypropylene, polyethylene terephthalate or polyvinyl chloride to form a coating layer is coated with polyvinyl chloride, polypropylene or polyethylene terephthalate Is formed by thermal lamination of a print layer made of a metal material.

상기한 선행기술에서는 다양한 소재의 기재 필름에 에틸렌비닐아세테이트 또는 저밀도 폴리에틸렌을 코팅하므로써 접착제 없이 다양한 소재를 열합판할 수 있고, 또한 친환경적인 효과가 있을 수 있으나, 이와 같이 제조되는 장식시트를 합판에 부착시킬 때에는 앞서 기술한 종래의 방법에 의하여 부착시키기 때문에 종래기술의 문제점을 전혀 해소할 수 없다는 문제가 있다. In the prior art described above, ethylene vinyl acetate or low density polyethylene is coated on a substrate film of various materials, so that it is possible to heat-laminate various materials without using an adhesive, and it may be eco-friendly. However, There is a problem in that the problem of the prior art can not be solved at all because it is attached by the conventional method described above.
