본 발명은 난연성을 갖는 함침무늬목의 제조방법 및 이용하여 제조된 합판에 관한 것으로서, 보다 상세하게는 각종 가구나, 건축물의 내외장재, 벽면 등에 적용되는 합판의 제조시 사용되어 난연성을 부여할 수 있도록 한 난연성을 갖는 함침무늬목의 제조방법과, 상기 함침무늬목을 사용하여 제조된 것으로 내수성이 우수하고, 화재의 발생시 불에 잘 타지 않아 화재에 의한 대형사고를 방지할 수 있는 난 연성 합판에 관한 것이다. The present invention relates to a method of manufacturing impregnated veneer having a flame retardancy and a plywood manufactured by using the flame retardant, which is used in the manufacture of plywood applied to various furniture, interior and exterior materials of the building, walls, etc. It relates to a method of manufacturing an impregnated veneer having a and a flame retardant plywood that is manufactured by using the impregnated veneer and has excellent water resistance and is not easily burned by fire when a fire occurs.
일반적으로 합판은 원목을 얇게 판상으로 절단시키고, 절단된 판상의 목재를 적층시킨 후 접착제로 접착시켜 제조하고 있다. 이렇게 제조된 합판은 각종 가구나, 건축물의 내외장재, 건축물의 벽면 등에 적용되고 있다. In general, plywood is manufactured by cutting a solid wood into a thin plate, laminating the cut plate-like wood and then bonding with an adhesive. The plywood thus manufactured is applied to various furniture, interior and exterior materials of buildings, walls of buildings, and the like.
그러나, 상기와 같이 제조된 합판을 단순히 판상의 목재를 적층시켜 제조된 것이므로 이를 내외장재로 활용하기 위해서는 그 표면에 별도로 제작된 무늬목을 부착하거나 도장을 실시하는 등의 후공정을 거치게 된다. However, since the plywood manufactured as described above is simply manufactured by laminating plate-like wood, in order to utilize it as an interior and exterior material, a post-process such as attaching a separately manufactured veneer or coating is performed on the surface thereof.
또한, 상기한 방법으로 제조된 기존의 합판은 목재로 제조됨에 따라 내수성이 약하여 물이나 습기등에 장기간 노출되면 썩거나 부풀어올라 터지는 결함을 가지고 있다. 뿐만 아니라 외부의 환경변화에 의해 쉽게 휘거나 변형이 일어나는 문제점이 있다. In addition, the conventional plywood produced by the above method is made of wood has a weak water resistance and has a defect that will rot or swell when exposed to water or moisture for a long time. In addition, there is a problem that bends or deformations are easily caused by external environmental changes.
아울러, 이와 같이 목재로 된 합판의 경우 불에 잘 타는 취약한 단점을 가지고 있어 화재 발생시 대형사고로 이어질 수 있는 문제점이 있다. 따라서 화재 발생시 불에 잘 타지 않는 합판의 개발이 매우 시급하게 요구되고 있는 실정이다. In addition, in the case of the plywood made in this way has a weak disadvantage that burns well, there is a problem that can lead to a large accident in the event of a fire. Therefore, the development of plywood that does not burn well in the event of fire is very urgently required.
이러한 요구에 부응하여 본 발명자는 별도의 후 공정 없이도 미려한 장식효과를 나타낼 수 있을 뿐만 아니라 난연성이 부여되어 불에 잘 타지 않으면서, 내수성이 우수한 합판을 연구한 끝에 본 발명을 완성하였다. In response to these demands, the present inventors completed the present invention after studying plywood having excellent water resistance while not only exhibiting a beautiful decorative effect without additional post-processing but also being provided with flame retardancy and not burning well.
따라서, 본 발명은 각종 가구나, 건축물의 내외장재, 벽면 등에 적용되는 합판의 제조시 사용되어 난연성을 부여할 수 있도록 한 난연성을 갖는 함침무늬목의 제조방법을 제공하는데 그 목적이 있다. Accordingly, an object of the present invention is to provide a method of manufacturing an impregnated veneer having a flame retardancy which is used in the manufacture of plywood applied to various furniture, interior and exterior materials of a building, a wall surface, and the like to impart flame retardancy.

이하 본 발명을 보다 상세하게 설명하면 다음과 같다. Hereinafter, the present invention will be described in more detail.
본 발명에 따른 난연성을 갖는 함침무늬목은 열경화성 수지 함침액에 탄산칼슘을 첨가 혼합하여서 된 난연함침액에 무늬목을 함침시킨 다음 건조하여 제조된다. Impregnated veneer having a flame retardancy according to the present invention is prepared by impregnating the veneer in the flame retardant impregnation liquid by adding and mixing calcium carbonate to the thermosetting resin impregnation liquid and then dried.
이때, 상기 난연함침액은 열경화성 수지 함침액 100중량부에 대하여 탄산칼슘을 60∼200중량부 첨가 혼합하여서 된 것이다. At this time, the flame-retardant impregnation liquid is obtained by mixing 60 to 200 parts by weight of calcium carbonate with respect to 100 parts by weight of the thermosetting resin impregnation liquid.
여기서 열경화성 수지 함침액은 통상의 시트 제조나 화장판 제조시 사용되는 멜라민수지, 페놀수지, 요소수지, 폴리에스테르수지, 에폭시수지 함침액에서 선택된 것을 적용하면 된다. Here, the thermosetting resin impregnation liquid may be selected from melamine resin, phenol resin, urea resin, polyester resin, epoxy resin impregnation liquid, which are used in the manufacture of ordinary sheets and decorative plates.
난연함침액은 상기한 통상의 열경화성 수지액침액에 탄산칼슘을 첨가 혼합하여 제조된 것인데, 이와 같이 탄산칼슘을 첨가하여 제조된 난연함침액은 우수한 난연효과를 나타낸다. 즉, 화재 발생시 고온에 의해 함침무늬목에 포함된 탄산칼슘이 분해되어 이산화탄소가 생성되며, 이렇게 생성된 이산화탄소는 소화능력을 가지고 있어 난연성을 가지게 된다. The flame retardant impregnation solution is prepared by adding and mixing calcium carbonate to the conventional thermosetting resin immersion liquid. The flame retardant impregnation solution prepared by adding calcium carbonate thus exhibits excellent flame retardant effect. In other words, calcium carbonate contained in the impregnated veneer is decomposed by the high temperature when a fire occurs, and carbon dioxide is produced, and thus the carbon dioxide produced has fire extinguishing ability.
이때, 탄산칼슘은 열경화성 수지 함침액 100중량부에 대하여 60중량부 미만으로 첨가할 경우 제조된 무늬목의 난연성이 충분히 개선되지 못하는 단점이 있으며, 그 첨가량이 200중량부를 초과할 경우 열경화성 수지 함침액과의 혼합이 용이하지 않아 작업성이 떨어지고 무늬목의 함침이 곤란하다는 문제점이 있으므로, 난연함침액은 열경화성 수지 함침액 100중량부에 대하여 탄산칼슘 60∼200중량부 첨가하여 제조된 것을 사용하는 것이 좋다. In this case, calcium carbonate has a disadvantage in that the flame retardancy of the manufactured veneer is not sufficiently improved when added to less than 60 parts by weight with respect to 100 parts by weight of the thermosetting resin impregnation solution, and when the addition amount exceeds 200 parts by weight, the thermosetting resin impregnation solution and Since there is a problem in that the mixing is not easy and the workability is poor and the veneer impregnation is difficult, it is preferable to use a flame retardant impregnation prepared by adding 60 to 200 parts by weight of calcium carbonate to 100 parts by weight of the thermosetting resin impregnation solution.
이렇게 열경화성 수지 함침액에 탄산칼슘을 첨가 혼합하여 제조된 난연함침액에 함침되는 무늬목은 합판이나 화장판 등의 제조에 일반적으로 사용되는 것을 적용하면 된다. Thus, the veneer impregnated in the flame retardant impregnation liquid prepared by adding and mixing calcium carbonate to the thermosetting resin impregnation liquid may be applied to those generally used in the manufacture of plywood and decorative plates.
이때, 상기 무늬목은 고형분함량이 30∼50%가 되도록 함침시키고 110∼150℃에서 건조하게 된다. 여기서, 고형분함량이 30% 미만일 경우 충분한 양의 탄산칼슘이 포함되지 않아 무늬목의 난연성 개선효과가 저하될 뿐만 아니라 접착력이 저하되는 단점이 있으며, 고형분함량이 50%를 초과할 경우 제조된 난연성을 갖는 함침무늬목을 사용하여 합판을 제조하는 과정에서 열가압 성형시 수지가 프레스 밖으로 흘러내리고 건조속도가 늦어지며, 특히 고형분함량이 50중량부를 초과하도록 함침 하는 것이 매우 곤란하다는 문제점이 있으므로, 무늬목의 고형분함량은 상기 범위 내로 하는 것이 좋다. At this time, the veneer is impregnated to a solid content of 30 to 50% and dried at 110 to 150 ℃. Herein, when the solid content is less than 30%, a sufficient amount of calcium carbonate is not included, so that the effect of improving the flame retardancy of the veneer is not only lowered, but also the adhesion is lowered, and when the solid content exceeds 50%, In the process of manufacturing plywood using impregnated veneer, the resin flows out of the press and slows down the drying rate, and in particular, it is very difficult to impregnate the solid content to exceed 50 parts by weight. It is good to carry out in the said range.
상기와 같이 무늬목을 난연함침액에 함침시킨 후 건조하면 본 발명에 따른 함침무늬목을 얻을 수 있는데, 건조는 110∼150℃에서 실시하면 되고, 휘발분 함량이 3.0∼5.0%가 될 때까지 건조하면 충분하다. After impregnating the veneer in the flame retardant impregnation solution as described above, the impregnated veneer according to the present invention can be obtained. The drying may be performed at 110 to 150 ° C., and the drying is sufficient until the volatile content is 3.0 to 5.0%. Do.
이렇게 제조된 함침무늬목은 난연성을 가지게 되는데, 이는 화재발생시 함침무늬목에 함유된 탄산칼슘이 고온에 의해 분해되어 이산화탄소를 발생시키면, 발생된 이산화탄소가 소화능력을 가지고 있어 우수한 난연성을 가지게 되는 것이다. The impregnated veneer thus prepared has flame retardancy, which means that when a fire occurs, the calcium carbonate contained in the impregnated veneer decomposes by high temperature to generate carbon dioxide, and thus the generated carbon dioxide has an extinguishing ability and thus has excellent flame retardancy.
상기와 같이 제조된 함침무늬목은 합판을 포함하여 각종 시트지의 제조에 사용될 수 있다. Impregnated veneer prepared as described above may be used in the manufacture of various sheet paper including plywood.
본 발명에 따르면 상기 함침무늬목을 이용하여 합판을 제조하는 방법과 상기 제조방법에 의해 제조된 합판을 제공한다. According to the present invention, there is provided a method of manufacturing plywood using the impregnated veneer and a plywood manufactured by the manufacturing method.
상기 합판의 제조방법은 열경화성 수지 함침액에 탄산칼슘을 첨가 혼합하여서 된 난연함침액에 무늬목을 함침시킨 다음 건조시켜 얻어진 함침무늬목을 적어도 1겹이상 적층하여 함침무늬목층을 형성하고, 상기 함침무늬목층의 상면과 하면에 각각 멜라민수지에 오버레이지를 함침시킨 다음 건조하여 얻어진 함침오버레이지를 적층하여 차단층을 형성하고, 상기 차단층 각각의 외표면에 무늬목을 적층하여 상하 무늬목층을 형성하고, 상기 상하 무늬목층의 외표면에 상기 함침오버레이지를 적층하여 함침오버레이지층을 형성한 다음 프레스상에서 열가압성형하는 것이다. The manufacturing method of the plywood is impregnated veneer veneer obtained by impregnating the veneer in the flame retardant impregnation liquid by adding and mixing calcium carbonate to the thermosetting resin impregnation liquid and then dried to form an impregnated veneer layer by forming at least one layer, the impregnated veneer layer The upper and lower surfaces of the melamine resin were impregnated with overlay paper, and then the impregnated overlay obtained by drying was formed to form a barrier layer. The veneer layer was formed on the outer surface of each barrier layer to form an upper and lower veneer layer. The impregnated overlay layer is formed by laminating the impregnated overlay layer on the outer surface of the layer, followed by thermopress molding on a press.
이렇게 제조된 합판은 도 1에 도시된 바와 같이 열경화성 수지 함침액에 탄 산칼슘을 첨가 혼합하여서 된 난연함침액에 무늬목을 함침시킨 다음 건조시켜 얻어진 함침무늬목을 적어도 1겹이상 적층하여 형성된 함침무늬목층(11)과, 상기 함침무늬목층(11)의 상면과 하면에 각각 멜라민수지에 오버레이지를 함침시킨다음 건조하여 얻어진 함침오버레이지를 적층하여 형성된 차단층(12,13)과, 상기 차단층(12,13) 각각의 외표면에 무늬목을 적층하여 형성된 상하 무늬목층(14,15)과, 상기 상하 무늬목층(14,15)의 외표면에 멜라민수지에 오버레이지를 함침시킨다음 건조하여 얻어진 함침오버레이지를 적층하여 형성된 함침오버레이지층(16,17)을 포함하게 된다. The plywood thus prepared is an impregnated veneer layer formed by stacking at least one or more layers of impregnated veneer obtained by impregnating the veneer in the flame retardant impregnation obtained by adding and mixing calcium carbonate to the thermosetting resin impregnation as shown in FIG. (11) and a barrier layer (12, 13) formed by laminating an impregnated overlay obtained by impregnating overlay paper on the upper surface and the lower surface of the impregnated patterned wood layer (11) and then drying, and the barrier layer (12, 13) The upper and
여기서, 함침무늬목을 제조하는 것에 대해서는 전술한 바와 같으며, 본 발명에서는 상기 함침무늬목을 적어도 1겹이상 적층하여 함침무늬목층(11)을 형성하게 된다. 함침무늬목의 적층개수는 제조할 합판의 두께를 고려하여 적절히 선택적으로 이루어질 수 있는 것이다. Herein, the manufacturing of the impregnated veneer is as described above, and in the present invention, the impregnated
상기 함침무늬목층(11)의 상면과 하면에는 각각 멜라민수지에 오버레이지를 함침시킨다음 건조하여 얻어진 함침오버레이지를 적층하여 형성된 차단층(12,13)이 형성된다. 이때 함침오버레이지는 멜라민수지에 오버레이지를 고형분함량이 60∼80%가 되도록 함침시키고 90∼110℃에서 건조시켜 얻어진 것을 사용하게 된다. On the upper and lower surfaces of the impregnated patterned
상기 차단층(12,13)은 함침무늬목의 열경화성수지가 열가압시 상·하부로 베어나와 무늬목층(14,15)으로 베어드는 것을 방지하기 위하여 형성된 것으로서, 오버레이지는 각종 가구나, 바닥재, 도어, 인테리어 용품에 일반적으로 적용되는 표면재를 사용하면 되고, 상기 오버레이지가 함침되는 멜라민수지는 통상의 시트 제 조나 화장판 제조시 사용되는 것을 적용하면 된다. The
상기 차단층(12,13) 각각의 외표면에는 무늬목을 적층하여 형성된 상하 무늬목층(14,15)이 형성된다. 여기서 무늬목은 전술한 바와 같이 합판이나 화장판 등의 제조에 일반적으로 사용되는 것을 적용하면 된다. On the outer surface of each of the
상기 상하 무늬목층(14,15)의 외표면에는 각각 함침오버레이지를 적층하여 형성된 함침오버레이지층(16,17)이 형성된다.
여기서, 함침오버레이지는 전술한 바와 같이 멜라민수지에 오버레이지를 고형분함량이 60∼80%가 되도록 함침시키고 90∼110℃에서 건조시켜 얻어진 것을 사용하게 된다. Here, the impregnation overlay is obtained by impregnating the overlay paper in the melamine resin so that the solid content is 60 to 80% and drying at 90 to 110 ° C as described above.
이때 오버레이지는 각종 가구나, 바닥재, 도어, 인테리어 용품에 일반적으로 적용되는 표면재로서 목무늬나 추상무늬 등 다양한 패턴이 형성된 것을 사용할 수 있는데, 이러한 문양을 갖는 오버레이지를 멜라민수지에 함침하여 얻어진 함침오버레이지를 최외측의 표면에 형성함에 따라 별도의 후가공 공정을 실시하지 않아도 합판의 표면이 미려하게 나타나는 이점이 있다. In this case, the overlay paper is a surface material generally applied to various furniture, flooring, doors, and interior items, and various patterns such as wood patterns or abstract patterns can be used. The overlay impregnated overlay obtained by impregnating the overlay paper with melamine resin with such a pattern is optimal. As it is formed on the outer surface, there is an advantage that the surface of the plywood is beautiful even without a separate post-processing step.
특히, 상기와 같이 함침오버레이지를 무늬목의 외표면에 적층하여 함침오버레이지층(16,17)을 형성하게 되면 표면의 마감뿐만 아니라 수지에 의해 내수성을 갖게 된다. 따라서 물이나 습기등에 장기간 노출되어도 썩거나 부풀어올라 터지는 것이 억제되며, 외부의 환경변화에 의해 쉽게 휘거나 변형이 일어나지 않는다는 이점이 있다.In particular, when the impregnated
상기와 같이 하여 적층이 완료되면 프레스상에서 열가압 성형하게 된다. 열 가압 성형은 다양한 조건에서 실시할 수 있으며, 바람직하게는 성형시 합판의 파열이나 변형을 고려하여 110∼150℃의 온도에서 20∼60분간 10∼60kgf/㎠의 압력하에서 실시하는 것이 좋다. When lamination is completed as described above, the thermoforming is performed on a press. Thermo-press molding may be carried out under various conditions. Preferably, the molding may be performed under pressure of 10 to 60 kgf / cm 2 for 20 to 60 minutes at a temperature of 110 to 150 ° C. in consideration of rupture or deformation of the plywood.
이렇게 얻어진 본 발명에 따른 합판은 각종 가구나, 건축물의 내외장재, 벽면 등에 사용될 수 있으며, 외표면에 각각 함침오버레이지가 형성되어 있어 미려한 장식효과를 얻을 수 있으며, 수지에 의해 내수성을 가진다. 아울러 내부에 내장된 함침무늬목에 의하여 난연성을 가지므로 화재의 발생시 불에 잘 타지 않아 화재에 의한 대형사고를 방지할 수 있는 이점이 있다. 특히 함침무늬목에 포함된 탄산칼슘은 화재 발생시 고온에서 이산화탄소를 발생시키며, 발생된 이산화탄소는 소화능력을 가지고 있어 난연성을 배가시키는 이점을 가지고 있다. Thus obtained plywood according to the present invention can be used for various furniture, interior and exterior materials of the building, wall, etc., the impregnated overlay is formed on the outer surface, respectively, to obtain a beautiful decorative effect, it has a water resistance by resin. In addition, since the impregnated veneer is built in flame retardancy, it does not burn well in case of fire, which has the advantage of preventing large accidents caused by fire. In particular, the calcium carbonate contained in the impregnated veneer generates carbon dioxide at high temperature during fire occurrence, and the generated carbon dioxide has an extinguishing ability and thus doubles flame retardancy.
