본 발명은 무늬목 시트에 관한 것으로, 더 상세하게는 합판, 중밀도 섬유판(MDF:Medium Density Fiber Board), 고밀도 섬유판(HDF:High Desity Fiber Board), PVC 타일, 스틸 패널(steel panel)등의 표면에 부착하여 천연무늬목의 질감, 촉감, 입체적 형상, 무늬 및 색감을 천연 그대로 살릴 수 있는 입체 목리를 갖는 무늬목 시트의 제조 방법 및 그 방법으로 제조한 입체 목리를 갖는 무늬목 시트에 관한 것이다.The present invention relates to a veneer sheet, and more particularly to the surface of plywood, medium density fiber board (MDF), high density fiber board (HDF), PVC tile, steel panel, etc. It relates to a method for producing a veneer sheet having a three-dimensional wood that can be attached to the texture, feel, three-dimensional shape, pattern and color of the natural veneer, and a veneer sheet having a three-dimensional wood produced by the method.

근래, 원목을 슬라이서를 이용하여 0.182mm 내지 0.5mm 두께로 얇게 절삭함으로써 얇은 무늬목을 얻고, 이를 MDF, HDF(이하, MDF 또는 HDF를 "보드"라고도 함), 합판, 합성수지 패널 등의 판재 표면에 접합하여 가구용 판재, 인테리어용 판재 등으로 사용한다. 이 때, 원목으로 부터 슬라이스된 천연 무늬목은 작업성을 위하여 시트 형태로 제작되어 사용된다. 즉, 천연 무늬목을 그대로 시트 형태로 만든 천연 무늬목 시트, 여러 장의 천연 무늬목을 적당히 재단한 후 수지나 접합사로 집성한 집성 무늬목 시트, 천연 무늬목을 스트립 형태로 재단하여 모자이크 형상으로 직조한 모자이크 무늬목 시트, 저급의 무늬목 시트 상에 고급의 무늬목 문양을 염색한 염색 무늬목 시트 등으로 성형되어 사용된다. 따라서, 이하에서는 집성 무늬목 시트, 천연 무늬목 시트 및 모자이크 무늬목, 염색 무늬목 시트를 통칭하여 무늬목이라고 한다. 이들 무늬목은 매우 얇아 손상되기 쉽고, 수분에 취약하며, 그대로는 판재 표면에 부착하기 어려우므로, 그 배면에 페놀 등 열경화성 수지를 함침한 크라프트지나 접착제가 함침된 부직포 등을 배접한 후 열압착하여 무늬목 시트 형태로 보관, 유통 및 사용하여 왔다. 수지 함침 크라프트지나 접착제 함침 부직포 등의 배접은 하부로 부터 수분이 침투하는 것을 방지하고, 강도를 보강하며, 보드나 합판등에 대한 접착성을 좋게 한다. Recently, thin wood is cut into 0.182mm to 0.5mm thickness using a slicer to obtain thin veneer, which is applied to the surface of plate materials such as MDF, HDF (hereinafter referred to as MDF or HDF "board"), plywood, and synthetic panel. It is used for joining furniture boards and interior boards. At this time, the natural veneer sliced from the solid wood is used in the form of a sheet for workability. In other words, natural veneer sheet made of natural veneer in the form of sheet, aggregate veneer sheet collected by resin or bonded after appropriately cutting several natural veneer, mosaic veneer sheet woven into mosaic by cutting natural veneer in strip form, It is molded and used as a dyed veneer sheet dyed with a high-quality veneer pattern on a low-grade veneer sheet. Therefore, in the following, aggregate veneer sheet, natural veneer sheet, mosaic veneer, and dyed veneer sheet are collectively referred to as veneer. Since these veneers are very thin, they are fragile, vulnerable to moisture, and difficult to adhere to the surface of the plate as they are, so they are kraft paper impregnated with thermosetting resins such as phenol or non-woven fabric impregnated with adhesive, and then thermo-compressed. It has been stored, distributed and used in sheet form. Backing of resin impregnated kraft paper or adhesive impregnated nonwoven fabric prevents water from penetrating from the bottom, reinforces strength, and improves adhesion to boards and plywood.

뿐만 아니라, 무늬목은 사용 도중 마찰 등에 의하여 쉽게 마모되거나 손상되므로 그 표면 강화를 위하여 무늬목 상면에 멜라민 함침 오버레이지를 적층하고 열압착하여 코팅된다. 무늬목에 수지 함침 크라프트지 또는 접착제 함침 부직포 등을 배접하거나, 멜라민 함침 오버레이지를 코팅하는 데는 열프레스에 의한 열압착이 사용된다. 멜라민 함침 오버레이지는 셀룰로오스지에 내마모 실리카 또는 알루미나를 분포시켜 성형한 오버레이지를 열경화성 수지인 멜라민 수지에 함침한 후 건조시킨 것이다. 이러한 멜라민 함침 오버레이지는 열압착할 경우 투명한 상태가 된다.In addition, the veneer is easily worn or damaged by friction or the like during use, so that the surface of the veneer is laminated with melamine impregnated overlay paper and coated by thermocompression to strengthen the surface. Thermo-compression by heat press is used to apply resin impregnated kraft paper or adhesive impregnated nonwoven fabric to the veneer or to coat melamine impregnated overlay paper. Melamine-impregnated overlay paper is formed by dispersing wear-resistant silica or alumina on cellulose paper and then drying the overlay paper by impregnating it with melamine resin, which is a thermosetting resin. The melamine impregnated overlay paper becomes transparent when thermally compressed.

종래의 멜라민 함침 오버레이지를 적층한 무늬목 시트 제조 과정에서는 열압착시 프레스의 평탄한 면에 의하여 천연무늬목이 갖는 표면의 목리(grains)가 모두 평탄화되어 버려, 천연무늬목이 원래 가지고 있던 목리의 형상, 질감 및 촉감이 상실되는 문제점이 있었다. 그 것은 멜라민 함침 오버레이지가 열프레스의 평탄한 면에 의하여 평탄화 되면서 경화되어 버리기 때문이다. 따라서, 무늬목 시트의 제조 과정 중 열압과정에서 입체적인 무늬목의 목리 등이 모두 평탄화 되어, 열압 후에는 천연무늬목의 형태, 입체감, 질감 등이 상실되게 되는 것이다. 이를 보완하기 위하여 열프레스의 가압면에 그루브를 형성하여 목리와 비슷한 요철이 멜라민 함침 오버레이지에 남게 하기도 하지만, 무늬목의 실제 목리와 그루브의 모양이나 형상이 일치하지 않아 천연무늬목의 형태, 입체감이나 질감을 그대로 느끼게 하지는 못하고 있다.In the process of manufacturing veneer sheet laminated with the conventional melamine impregnated overlay paper, all the grains of the surface of natural veneer have been flattened by the flat surface of the press during thermocompression, so that the shape, texture and There was a problem that the touch is lost. This is because the melamine impregnated overlay paper is hardened while being flattened by the flat surface of the heat press. Therefore, the three-dimensional veneer of the three-dimensional veneer in the manufacturing process of the veneer sheet is flattened, after the thermal pressure, the shape, three-dimensional, texture, etc. of the natural veneer will be lost. To compensate for this, grooves are formed on the pressing surface of the heat press, so that unevenness similar to wood remains on the melamine-impregnated overlay paper.However, since the actual wood of the veneer does not match the shape or shape of the groove, the shape, solidity and texture of the natural veneer It doesn't make you feel it.

상술한 종래 무늬목 시트의 제조 방법이 갖는 문제점을 해결하고자 안출된 본 발명은 무늬목 시트의 제조 과정에서 무늬목 상면에 멜라민 함침 오버레이지를 코팅하면서도 목리의 평탄화나 훼손 없이, 입체적인 천연무늬목의 목리를 그대로 살려, 자연적인 질감, 색감 및 입체감을 느낄 수 있는 입체 목리를 갖는 무늬목 시트의 제조 방법 및 그 방법으로 제조한 입체 목리를 갖는 무늬목 시트를 제공하는 데 그 목적이 있다. The present invention devised to solve the problems of the above-described method of manufacturing a veneer sheet, while coating the melamine impregnated overlay paper on the top surface of the veneer sheet in the manufacturing process of the veneer sheet, without the flattening or damage of the tree, the tree of the three-dimensional natural veneer, It is an object of the present invention to provide a method for producing a veneer sheet having a solid wood which can feel a natural texture, color and three-dimensional feeling, and a veneer sheet having a solid wood produced by the method.

상술한 목적을 달성하고자 하는 본 발명에 따른 입체 목리를 갖는 무늬목 시트의 제조 방법은 Method for producing a veneer sheet having a three-dimensional wood according to the present invention to achieve the above object

무늬목 하부에 접착제 함침 부직포 또는 수지 함침지를 배접하고, 무늬목 상면에는 멜라민 함침 오버레이지를 합지한 후 열압착하여 성형되는 무늬목 시트에 있어서, 열압착시 상기 멜라민 함침 오버레이지 상면에 금속 박막을 올려 놓고 열압착하여, 무늬목의 목리가 입체적으로 살아나게 한 것을 특징으로 한다.In the veneer sheet formed by bonding the adhesive impregnated non-woven fabric or resin impregnated paper to the lower part of the veneer, and laminating the melamine impregnated overlay paper on the upper surface of the veneer, and heat-compressing the sheet. It is characterized in that the wood of the veneer is raised three-dimensionally.

이 때 상기 무늬목은 천연 무늬목 시트, 집성 무늬목 시트, 모자이크 무늬목 시트, 염색 무늬목 시트를 포함한다.At this time, the veneer includes a natural veneer sheet, aggregate veneer sheet, mosaic veneer sheet, dyed veneer sheet.

이하, 첨부한 도면을 참조하여 본원 발명의 바람직한 실시 예를 상세히 설명한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본원 발명은 천연무늬목 단판, 천연무늬목 시트 및 모자이크 무늬목에 모두 적용가능하나, 첨부한 도면에는 천연무늬목 시트와 모자이크 무늬목을 이용하여 무늬목 시트를 제조하는 경우를 예시적으로 도시하였다. 또한, 무늬목 하부에는 페놀수지, 멜라민 수지, 요소 수지 등 열경화성 수지를 크라프트지에 함침한 수지 함침 크라프트지가 배접될 수 도 있으나, 첨부한 도면에서는 예시적으로 접착제 함침 부직포를 배접한 경우를 도시하였다.The present invention is applicable to both natural veneer veneer, natural veneer sheet and mosaic veneer, the accompanying drawings illustrate a case of manufacturing a veneer sheet using a natural veneer sheet and mosaic veneer. In addition, a resin-impregnated kraft paper impregnated with a thermosetting resin such as a phenol resin, melamine resin, and urea resin may be disposed on the lower part of the veneer, but in the accompanying drawings, an adhesive impregnated nonwoven fabric is illustrated as an example.

도 1은 금속 박막(3), 멜라민 함침 오버레이지(4), 천연무늬목 시트(1a) 및 접착제 함침 부직포(2)를 이용하여 입체 목리를 갖는 무늬목 시트를 열압착에 의하여 제조하는 경우, 각 구성요소의 적층 순서를 보여 주는 분리 사시도이다.FIG. 1 shows that when a veneer sheet having three-dimensional grains is manufactured by thermocompression bonding using a metal thin film 3, melamine-impregnated overlay paper 4, natural veneer sheet 1a, and adhesive-impregnated nonwoven fabric 2 An exploded perspective view showing the stacking order of the elements.

도 1을 참조하면, 열프레스에 의하여 본 발명에 따른 입체 목리를 갖는 무늬목 시트를 제조하기 위하여는 우선 접착제 함침 부직포(2)를 가장 하부에 배치하고, 그 상부에 천연무늬목 시트(1a)를 적층하며, 상기 천연무늬목 시트(1a) 상부에 멜라민 함침 오버레이지(4)를 적층한다. 그리고, 마지막으로 금속 박막(3)을 멜라민 함침오버레이지(4) 상에 적층한다. 열프레스에 의하여 상기 금속 박막(3)의 상면을 열압착하여 상기 접착제 함침 부직포(2), 천연무늬목 시트(1a) 및 멜라민 함침 오버레이지(4)를 일체로 접착시킨다. 이 때, 접착은 부직포에 함침된 접착제와, 가열된 멜라민 함침 오버레이지의 용융 멜라민 수지에 의하여 이루어진다. 접착이 완성된 후 상기 금속 박막(3)은 제거된다.Referring to Figure 1, in order to manufacture a veneer sheet having a three-dimensional wood according to the present invention by hot pressing, first, the adhesive-impregnated nonwoven fabric 2 is disposed at the bottom, and the natural veneer sheet 1a is laminated thereon. Then, the melamine impregnated overlay paper (4) is laminated on the natural veneer sheet (1a). Finally, the metal thin film 3 is laminated on the melamine impregnation overlay 4. The upper surface of the metal thin film 3 is thermally compressed by thermal press to integrally bond the adhesive impregnated nonwoven fabric 2, the natural veneer sheet 1a, and the melamine impregnated overlay paper 4. At this time, the adhesion is made by an adhesive impregnated in the nonwoven fabric and the molten melamine resin of the heated melamine impregnated overlay paper. After the adhesion is completed, the metal thin film 3 is removed.

본 발명의 특징은 무늬목의 입체적인 목리나 문양이 그대로 살아 날 수 있도록 하기 위하여, 열압착 전에 무늬목 상면에 소성이 크고 무른 금속 박막(3)을 올려 놓는데 있다. 금속 박막(3)으로는 알루미늄 호일, 은박지 등이 적당하나 반드시 이에 한정되는 것은 아니며, 열프레스에 의하여 압착할 경우 하부에 구비된 무늬목의 입체적인 목리가 금속 박막(3)에 각인되어 보호될 수 있을 정도로 무른 금속 박막이나 이와 대체적으로 사용 가능한 소재의 박막이면 충분하다. 이렇게 함으로써, 열압과정에서 입체적인 무늬목의 목리가 평탄화되지 않고, 열압착 후에도 그대로 남게 된다.A feature of the present invention is to place a plastic film having a large and soft plasticity on the upper surface of the veneer before thermocompression so that three-dimensional grains or patterns of the veneer can survive. Aluminum foil, silver foil, etc. are suitable as the metal thin film 3, but are not necessarily limited thereto. When pressing by heat press, three-dimensional wood of the veneer provided at the bottom may be imprinted on the metal thin film 3 to be protected. A thin metal thin film or a thin film of a generally usable material is sufficient. By doing so, the wood of the three-dimensional veneer is not flattened in the thermocompression process, and remains even after thermocompression bonding.

상기 접착제 함침 부직포(2)에 함침되는 접착제는 초산비닐계 접착제인 것이 바람직하다. 부직포를 초산비닐계(PVAc:PolyVinylAcetate) 접착제로 함침하여 열압착할 경우, 페놀수지 등을 함침한 크라프트지에 비하여 환경 오염의 염려가 없으면서도, 수분 침투가 효과적으로 차단되고, 보드나 합판 등에 대한 접착성이 좋아 바람직하다.It is preferable that the adhesive agent impregnated in the said adhesive impregnation nonwoven fabric 2 is a vinyl acetate type adhesive agent. When the nonwoven fabric is impregnated with PVAc (PolyVinylAcetate) adhesive and thermo-compressed, water penetration is effectively blocked and there is no risk of environmental pollution compared to kraft paper impregnated with phenolic resin, and adhesiveness to board or plywood This is preferable and good.

상기 천연무늬목 시트(1a)의 배면에 접착제 함침 부직포(2)를 우선 가접합 한 후 텐더라이저에 의하여 유연화하고, 여기에 상기 멜라민 함침 오버레이지(4)와 금속 박막(3)을 적층하여 열압착할 수도 있다. 본 발명에 따른 무늬목을 보드나 합판의 가장자리의 곡면에 부착하기 용이하게 하기 위하여 유연화 공정을 더 거칠 수 있는 것이다. 따라서, 목질 또는 용도에 따라 유연화가 더 이상 필요하지 않을 경우에는 텐더라이저에 의한 유연화 공정은 불필요하다.The adhesive impregnated nonwoven fabric 2 is first temporarily bonded to the back surface of the natural veneer sheet 1a, and then softened by a tenderizer, and the melamine impregnated overlay paper 4 and the metal thin film 3 are laminated thereon and thermally compressed. You may. In order to facilitate the attachment of the veneer according to the invention to the curved surface of the edge of the board or plywood, the softening process may be further roughened. Therefore, the softening process by the tenderizer is unnecessary when the softening is no longer necessary depending on the wood or the application.

도 1에 도시된 바와 같이 아래로 부터 순차적으로 적층된 접착제 함침 부직포(2), 천연무늬목 시트(1a) 및 멜라민 함침 오버레이지(4)는 열프레스에 의하여 열압착되어 일체가 된다. 이 때, 열프레스에 의한 열압착은 30~35Kg/㎠ 압력하에서 온도를 160℃까지 점증시키면서 열압착하며, 100℃이하에서 10~20분, 100℃ 이상에서 40 ~ 50분간 열압착하는 것이 바람직하다. 이 것은 멜라민 오버레이지에 함침된 멜라민 수지와 부직포에 함침된 초산비닐계 접착제가 용융되어 무늬목 상면 또는 하면에 침투한 후 경화하는 데 필요한 압력, 온도 및 시간이다. 이러한 조건으로 열압착하여야, 사용 중 물이나 습기가 스며들거나 열이 가해지더라도 부직포가 쉽 게 분리되지 않는다. 열압착이 끝나면, 금속박막(3)은 제거되며, 냉각에 의하여 접착제 함침 부직포(2), 천연무늬목 시트(1a) 및 멜라민 함침 오버레이지(4)가 층을 이루면서도 멜라민 함침 오버레이지(4)에 무늬목의 목리가 그대로 구현된 무늬목 시트를 얻게 된다.As shown in FIG. 1, the adhesive impregnated nonwoven fabric 2, the natural veneer sheet 1a, and the melamine impregnated overlay paper 4 sequentially stacked from below are thermally compressed and integrated by a heat press. At this time, thermocompression bonding by heat press is thermocompression while increasing the temperature up to 160 ° C under pressure of 30-35Kg / cm 2, and thermocompression bonding under 10 ° C at 100 ° C and 40-50 minutes at 100 ° C or higher. Do. This is the pressure, temperature and time required for the melamine resin impregnated in the melamine overlay paper and the vinyl acetate-based adhesive impregnated in the nonwoven fabric to melt and penetrate the upper or lower surface of the veneer, and to cure. Thermocompression under these conditions prevents the nonwovens from easily separating even if water, moisture, or heat are applied during use. At the end of the thermocompression bonding, the metal thin film 3 is removed, and by cooling, the adhesive impregnated nonwoven fabric 2, the natural veneer sheet 1a, and the melamine impregnated overlay paper 4 are layered and the melamine impregnated overlay paper 4 is formed. You will get a veneer sheet with the wood of the veneer.

도 2는 금속 박막(3), 멜라민 함침 오버레이지(4), 모자이크 무늬목(1b) 및 접착제 함침 부직포(2)를 이용하여 입체 목리를 갖는 무늬목 시트를 열압착에 의하여 제조하는 경우, 각 구성요소의 적층 순서를 보여 주는 분리 사시도이다.FIG. 2 shows that when a veneer sheet having three-dimensional grains is manufactured by thermocompression bonding using a metal thin film 3, melamine-impregnated overlay paper 4, mosaic veneer 1b, and adhesive-impregnated nonwoven fabric 2, each component Is an exploded perspective view showing the stacking order of the.

도 2에 도시된 실시 예가 도 1에 도시된 실시 예와 다른 점은 천연무늬목 시트(1a) 대신에 모자이크 무늬목(1b)을 사용한 점에 있다. 모자이크 무늬목(1b)을 사용할 경우 유연성이 우수하고, 다양한 디자인을 갖는 무늬목 시트를 만들 수 있다.2 differs from the embodiment illustrated in FIG. 1 in that the mosaic veneer 1b is used instead of the natural veneer sheet 1a.
