본 발명은 천연무늬목에 고기능성을 부여하기 위한 고기능성 천연무늬목 제조방법에 관한 것으로, 더욱 상세하게는 원목으로부터 얇게 켜진 무늬목을 치수안정처리, 보존처리등을 실시함으로써 안정된 래핑재료등으로 사용하기 위한 고기능성 천연무늬목 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a high-performance natural veneer for imparting high functionality to the natural veneer, and more specifically, to use as a stable wrapping material, etc. by performing a dimensional stability treatment, preservation treatment, etc. It relates to a method for producing high functional natural veneer.

목재가 갖는 천연적인 질감과 유려한 심미성 때문에 건축물에 마감재로 많이 사용되어 왔고, 래핑(rapping)기술이 발달함에 따라서, 파티클 보드(particle board), 중밀도섬유판(medium density fiber board), PVC, 알루미늄 등의 표면에 비닐계, PVC계, 무늬인쇄용지, LPM(Low Pressure Melamine), HPM(High Pressure Melamine)등의 래핑재료를 사용하여 래핑 또는 오버레이(overlay)를 실시하여 왔다. 그러나, 이러한 래핑재료에 의한 래핑은 천연의 목재의 질감과 심미감을 구현하는 데에 어려움이 있었다. 따라서, 래핑재료로서 천연무늬목에 대한 요구가 꾸준히 증가되고 있었으나, 천연무늬목은 수종에 따른 재질의 차이가 나고, 고흡수성,고흡습성, 부후성등으로 찢어지기 쉽고, 접을 수가 없으며, 수분에 의한 치수변동이 심할 뿐만 아니라 곰팡이 발생등으로 래핑재료로 사용하기에는 부적절하였다. 최근에 천연무늬목은 벽지로도 개발되어졌으나, 접착제의 건조시 무늬목이 수축하여 틈새가 발생되고, 무늬목과 무늬목의 이음부위에서 갈라짐등이 발생하는 등 여러 가지의 문제점들을 갖고 있다.Due to the natural texture and elegant esthetics of wood, it has been widely used as a finishing material in buildings, and as the wrapping technology is developed, particle board, medium density fiber board, PVC, aluminum Wrapping or overlaying has been performed on the surface of the back using a wrapping material such as vinyl, PVC, pattern printing paper, low pressure melamine (LPM), high pressure melamine (HPM), or the like. However, lapping by such lapping materials has been difficult to realize the texture and aesthetics of natural wood. Therefore, the demand for natural veneer as a wrapping material has been steadily increasing. However, natural veneer has a different material depending on the species, and it is easily torn due to its high absorbency, high hygroscopicity, and thickening, and cannot be folded. Not only was it fluctuating, it was also unsuitable for use as a wrapping material due to mold development. Recently, natural veneer has been developed as a wallpaper, but there are various problems such as cracking due to shrinkage of the veneer when the adhesive is dried, cracking at the joint part of the veneer and veneer.

본 발명은 이러한 문제점들을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 천연무늬목이 갖는 우수한 질감과 심미감은 최대한 살리면서, 고흡습성, 고흡수성, 부후성등의 문제점들을 해결하기 위한 천연무늬목의 고기능화 방법을 제공하기 위한 것이다.The present invention has been devised to solve these problems, the object of the present invention is to improve the natural veneer of natural veneer, while maintaining the excellent texture and aesthetics to the maximum, to solve the problems of high hygroscopicity, superabsorbency, thickening, etc. It is to provide a method.

상기 목적을 위하여 본 발명은, 천연무늬목의 함유수분변화시 발생될 치수변동을 억제하기 위한 충진제가 용해된 용액중에 상기 천연무늬목을 함침시킨 후 건조시키는 치수안정화 단계를 포함하는 것을 특징으로 하는 천연무늬목 제조방법에 있어서, 상기 충진제속에 함침시키는 단계전에 상기 천연무늬목의 일측면에 얇은 시트형 판지를 접착하는 단계를 더 포함하는 것을 특징으로 한다.For this purpose, the present invention, the natural veneer comprising a dimensional stabilization step of drying after impregnating the natural veneer in a solution in which a filler for suppressing the dimensional change generated when the moisture content of the natural veneer is changed In the manufacturing method, further comprising the step of adhering a thin sheet-like cardboard on one side of the natural veneer before impregnating the filler.

상기 시트형 판지는 종이류 또는 비닐 시트지가 바람직하다.The sheet-shaped cardboard is preferably paper or vinyl sheet paper.

상기 충진제는 폴리에틸렌글리콜(polyethylene glycol) 수용액이 바람직하다.The filler is preferably an aqueous polyethylene glycol solution.

상기 수용액의 농도는 20% 이상으로 하는 것이 바람직하다.It is preferable that the density | concentration of the said aqueous solution shall be 20% or more.

상기 수용액의 온도는 20 내지 50。C로 하는 것이 바람직하다.It is preferable that the temperature of the said aqueous solution shall be 20-50 degreeC.

상기 보존처리제는 붕산나트륨 분말의 수용액인 것이 바람직하다.The preservative is preferably an aqueous solution of sodium borate powder.

상기 보존처리제의 수용액의 농도는 10% 내지 50% 인 것이 바람직하다.The concentration of the aqueous solution of the preservative is preferably 10% to 50%.

상기 보존처리제의 수용액의 농도는 청변(blue stain)이 심한 수종일수록 고농도, 심하지 않은 수종일수록 저농도로 하는 것이 바람직하다.It is preferable that the concentration of the aqueous solution of the preservative is higher in the number of blue stains and in low concentrations in the less severe species.

또한, 본 발명에서 치수안정화단계와 보존처리단계는 동시에 실시하는 것이 바람직하다.In the present invention, the dimensional stabilization step and the preservation step are preferably performed at the same time.

또한, 본 발명에서 표면도장단계에서 연성의 UV경화형 우레탄수지를 도장하는 과정을 더 포함하는 것이 바람직하다.In addition, the present invention preferably further comprises the step of coating a soft UV curable urethane resin in the surface coating step.

또한, 상기 우레탄수지의 도막두께는 100μm 이하인 것이 바람직하다.Moreover, it is preferable that the coating film thickness of the said urethane resin is 100 micrometers or less.

또한, 본 발명은 상기의 공정에 의하여 제조되는 고기능성 천연무늬목을 특징으로 한다.In addition, the present invention is characterized by a highly functional natural veneer produced by the above process.

이하, 본 발명의 구성에 대하여 상세히 설명하기로 한다.Hereinafter, the configuration of the present invention will be described in detail.

원목으로부터 얇게 켠 천연무늬목이 일정 두께 이상인 경우에는 그대로 충진제의 수용액에 함침을 하고, 일정두께 이하인 경우에는 천연무늬목의 이면에 얇은 종이시트지나, 비닐시트지와 같은 얇은 시트형 판지를 접착시켜 후 공정에서 천연무늬목이 찢어지거나, 변형되는 것을 최소화 한다.If the natural veneers thinned from solid wood are more than a certain thickness, they are impregnated with an aqueous solution of filler as it is. If the thickness is less than a certain thickness, a thin sheet-like cardboard such as a sheet of paper or a vinyl sheet is adhered to the back of the natural veneers. Minimize tearing or deformation of the veneer.

이때 충진제는 폴리에틸렌 글리콜(PEG; polyethylene glycol)이 적합하며, PEG 수용액의 농도는 20% 이상이 바람직하며, 처리온도는 20 °C 내지 50 °C가 바람직하다. 수용액의 농도가 20% 이하인 경우에는 무늬목의 세포공극에 충진시키는 효과가 작고, 처리온도가 20 °C 이하일 경우에는 만족할 만한 충진효과를 기대하기가 어렵고, 50 °C를 초과하는 경우에는 과포화상태가 되어 건조시간이 장기화된다. 충진의 효과와 건조시간등을 고려할 때 40 °C 가 바람직하다. 이와 같은 함침을 시킨 후 천연무늬목을 건조시키면 무늬목의 공극 및 세포간극에 PEG분자가 잔류하게 되어 무늬목의 치수안정성을 향상시킬 뿐만 아니라 무늬목이 찢어지지 않고 유연하게 접힐 수 있는 성질을 구비하게 된다.At this time, the filler is polyethylene glycol (PEG) is suitable, the concentration of the PEG aqueous solution is preferably 20% or more, the treatment temperature is preferably 20 ° C to 50 ° C. When the concentration of the aqueous solution is 20% or less, the effect of filling the cell pores of the veneer is small, and when the treatment temperature is 20 ° C or less, it is difficult to expect a satisfactory filling effect. As a result, the drying time is prolonged. Considering the effect of filling and drying time, 40 ° C is preferred. When the natural veneer is dried after such impregnation, PEG molecules remain in the pores and cell gaps of the veneer, thereby improving the dimensional stability of the veneer and having the property of flexing the veneer without tearing.

상기 치수안정화단계 후에는 무늬목의 내부후성 및 내공팜이성을 부가하기 위해 보존처리를 실시한다. 목재의 보존처리제는 시중에 다양하게 시판되는 목재용 보존처리제를 사용할 수 있으나, 이러한 것들은 포르말린계통의 것으로 인체에 유해한 영향을 가져올 수 있으므로 무해한 곰팡이 방지제를 사용하는 것이 바람직하다. 바람직하기로는 붕산나트륨분말을 물에 용해시켜 사용하되, 붕산나트륨의 농도는 10 내지 50% 까지 다양하게 사용할 수 있다. 이때, 청변(blue stain)이 심한 침엽수계통의 수종은 고농도의 수용액을 사용하고, 변색이 심하지 않은 수종의 천연무늬목에 대하여는 저농도로 한다.After the dimensional stabilization step, preservation treatment is performed to add weather resistance and porosity resistance of the veneer. Wood preservatives may be used for various commercially available wood preservatives, but these are formalin-based, because it may have a harmful effect on the human body, it is preferable to use a harmless fungicide. Preferably, the sodium borate powder is used by dissolving it in water, and the concentration of sodium borate may be used in various ways from 10 to 50%. At this time, the species of the coniferous tree with a severe blue stain use a high concentration of aqueous solution, and the low concentration for the natural veneer of the species that is not discolored severely.

또한, 치수안정처리와 보존처리단계는 PEG와 붕산나트륨이 모두 수용성이므로 물에 PEG와 붕산나트륨을 동시에 용해시켜 한번의 공정으로 마칠 수 있다.이때, 무늬목내의 약재의 함침량은 원목의 수종에 따라 약제의 침투성이 상이하므로 조절이 필요하지만 무늬목의 전건중량 기준으로 30% 이상 함침되도록 처리시간을 조절하는 것이 바람직하다.In addition, since the PEG and sodium borate are both water-soluble, the pulp stabilization treatment and the preservation treatment step can be completed by dissolving PEG and sodium borate in water at the same time in one step. Since the permeability of the drug is different, adjustment is necessary, but it is preferable to adjust the treatment time so as to be impregnated by 30% or more based on the total dry weight of the veneer.

상기 보존처리공정을 실시한 후에 천연무늬목의 표면에 내오염성, 내마모성, 내세척성, 그리고 내후성을 향상시키기 위하여 표면도장을 한다. 래핑후에 도장을 하는 것이 이상적이라 할 수 있으나, 래핑자재는 요철부위가 많아 표면도장하기가 곤란하고, 대량생산 체제에서는 보존처리공정 후에 표면도장을 실시하여 래핑을 하는 것이 유리하다. 기존의 표면도장 재료로는 목공용 도료가 일반적이라 할 수 있으나, 이러한 도료에 의한 표면도장은 경화 후에 단단한 피막을 형성하게 되어 래핑과정에서 천연무늬목이 부러지거나 찢어지는 현상이 발생하게 되고, 예각진 부분을 래핑하는 경우에 이러한 현상이 두드러지게 나타난다. 따라서 표면도장 후에도 유연성을 갖도록 하기 위하여 침투성 천연오일(건성유)을 표면에 붓도장 혹은 스프레이도장을 한다. 또한, 표면도장은 연성의 UV경화형 우레탄수지를 도장함으로써 단시간에 대량의 천연무늬목을 도장할 수 있다. 연성의 UV경화형 우레탄수지를 도장은 수회에 걸쳐 실시될 수 있으나, 유연성을 잃지 않기 위하여 도막두께가 100μm를 넘지 않도록 한다.After performing the preservation treatment process, the surface of the natural veneer is coated with a surface to improve stain resistance, abrasion resistance, washing resistance, and weather resistance. It may be ideal to apply the coating after lapping, but the lapping material has many uneven parts, which makes it difficult to coat the surface. In the mass production system, it is advantageous to perform lapping by surface coating after the preservation treatment process. Conventional surface coating materials may be referred to as woodworking paints, but surface coatings by such paints form a hard film after curing, which causes natural veneer to break or tear during lapping. This phenomenon is noticeable when the part is wrapped. Therefore, in order to have flexibility even after surface coating, penetrating or spray coating of permeable natural oil (dry oil) is performed on the surface. In addition, the surface coating can coat a large amount of natural veneer in a short time by coating a soft UV-curable urethane resin. Coating may be carried out several times, but flexible UV-curable urethane resin, so that the coating thickness does not exceed 100μm in order not to lose flexibility.

이하, 구체적인 실시예에 대하여 설명하기로 한다.Hereinafter, specific embodiments will be described.

두께 0.28mm 인 스프루스 무늬목에 농도30% PEG-1000용액에 붕산나트륨 분말을 20% 농도로 용해시킨 후 무늬목을 2분 함침하여 롤타입의 건조기에서 건조한 무늬목을 PVC창호재에 래핑한 후, 물속에 3일 넣었다가 꺼낸 결과, 수분차단효과가 우수하여 무늬목의 형상이 변화되거나, 변색현상이 일어나지 않았다. 그러나, 비교대상의 무처리된 무늬목에는 심한 변색과 변형이 일어났다.Sodium borate powder was dissolved in a 30% PEG-1000 solution at a concentration of 0.28mm in spruce veneer, and 20% of sodium borate powder was impregnated. As a result of putting it in and taking it out for 3 days, the moisture barrier effect was excellent, so that the shape of the veneer did not change or discolored. However, severe discoloration and deformation occurred in the untreated veneer of the comparison.
