Description

무늬목 판재의 도장방법{Painting Method of Pattern Wood}Painting Method of Pattern Wood

본 발명은 목제 무늬목 판재의 도장방법에 관한 것으로, 보다 상세하게는 무늬목의 눈메꿈성(Fillering)도장 공정을 개선하여 도료의 절감과 작업성의 향상을 가져올 수 있도록 한 것이다.The present invention relates to a method of coating a wood veneer board, and more particularly, to improve the painting process of the wood veneer (Fillering) coating to reduce the paint and improve the workability.

일반적으로 합판과 같은 목재의 표면에 무늬목을 접착하여 제조되는 목제 무늬목 판재는 건축물의 내장재인 온돌마루나 각종 가구의 재료로 널리 사용되며, 이러한 무늬목 판재는 목재의 표면에 무늬목을 접착제로 접착하는 공정과 판재의 투명성및 평활성의 확보를 위한 수회의 도장공정을 거쳐 제조된다.Generally, wood veneer board manufactured by attaching veneer to the surface of wood such as plywood is widely used as a material for ondol floor, which is the interior material of buildings, and various furniture, and this veneer board is a process of adhering veneer to the surface of wood with adhesive Manufactured through several coating processes to ensure transparency and smoothness of the plate.

도 1은 종래 목제 무늬목 판재 도장 방법의 일예를 나타낸 공정도로서 무늬목 판재의 도장은 접착된 무늬목을 센딩하는 단계와, 다이렉트 롤 코터(Direct Roll Coater)에 의해 무늬목의 표면에 하도(下途)용 도료를 도포하는 단계와, 리버스 롤 코터(Reverse Roll Coater)에 의해 무늬목 표면에 도포된 젖은 상태의 도료를 눌러 그레인(나무결처럼 오목한 부위)으로 말어 넣음으로서 눈메꿈을 하는 단계와, 자외선에 의해 무늬목의 표면에 도포된 도료를 건조 경화시키는 단계와, 눈메꿈이 된 무늬목 위에 중도(中途)와 상도(上途)를 하는 공정으로 이루어진다.1 is a process diagram showing an example of a conventional wood veneer sheet coating method, the coating of the veneer sheet material is a step of sending the adhesive veneer, and a paint for the undercoat on the surface of the veneer by a direct roll coater (Direct Roll Coater) The step of applying the paint, and rolling the wet paint applied to the surface of the veneer by Reverse Roll Coater to roll it into the grain (concave-like concave), It consists of the process of carrying out dry hardening of the coating material apply | coated on the surface, and the process of carrying out intermediate | middle and top coat on the veneer which became snow-dried.

상기에서 무늬목의 센딩은 무늬목 표면의 거친 부분을 페이퍼 등으로 연마하는 공정으로, 무늬목의 표면에 있는 불순물이나 목제 판재에서 베어나오는 파라핀 등의 침전물을 절삭하고 매끄럽게 다듬어 주기 위한 것이다.In the above, the veneering of the veneer is a process of polishing a rough part of the surface of the veneer with a paper or the like to cut and smooth out impurities such as impurities on the surface of the veneer or paraffin deposits from the wood board.

상기 리버스 롤 코터에서 눈메꿈을 할 때 사용하는 도료로 아이솔레이터 도료가 널리 사용되며, 이 도료는 무늬목의 눈메나 목구를 차단하여 무늬목과 도료의 부착력을 증대시키고 이러한 부착력의 증대에 의해 차후 무늬목에 외부 충격이나 뒤틀림이 생기는 경우에도 도막의 깨짐이나 갈라짐이 최소한으로 억제된다.Isolator paint is widely used as a paint used to make eyes in the reverse roll coater, and this paint blocks the eyes and neck of the veneer, thereby increasing the adhesion of the veneer and the paint, and by increasing the adhesion, it is external to the veneer later. Even when an impact or distortion occurs, cracking or cracking of the coating film is minimized.

상기 중도와 상도용으로 사용되는 도료는 눈메꿈성과 살오름성이 좋은 연성의 에폭시 타입 도료와, 도막의 투명성과 평활도가 뛰어난 연성의 도료가 사용되는 것이 바람직하며, 그 외 우레탄이나 니스, 호마이카, 에폭시 등을 스프레이나 붓으로 도장하여 마감할 수도 있다.The paint used for the above-mentioned medium and top coats is preferably a soft epoxy type paint with good eye comfort and freshness, and a soft paint excellent in transparency and smoothness of the coating film. You can also finish by painting epoxy with a spray or brush.

또한 한번의 중도와 상도로 원하는 정도의 도막이나 평활도를 얻지 못하거나 또는 이루고자 하는 특성을 얻을 수 없을 때에는 상기 공정을 부분적으로 반복하거나 이들 공정을 혼용하여 실행할 수 있다.In addition, when the desired degree of coating or smoothness cannot be obtained or the desired characteristics can not be obtained with a single degree of midway and topography, the above steps may be partially repeated or a combination of these processes may be performed.

상기와 같은 종래의 방법은 다이렉트 롤 코터에서 무늬목의 표면에 하도용 도료를 도포한 후 리버스 롤 코터에서 무늬목의 그레인을 눈메꿈하는 작업이 행하여지기 때문에 다음과 같은 문제점이 있다.The conventional method as described above has the following problems because the work of grating the grain of the veneer in the reverse roll coater after applying the coating material for the surface of the veneer in the direct roll coater is performed.

즉, 종래 방법에 의하면 무늬목 판재가 다이렉트 롤 코터에 상,하로 설치된 롤러 사이를 통과하는 동안 상부에 설치된 롤러가 무늬목의 표면에 도료를 묻혀 도포하는 방법이어서 무늬목의 표면으로 한번에 충분한 양의 도료를 도포하는 것이 곤란하고 따라서 이후 리버스 롤 코터에 의해 눈메꿈 작업을 수행할 때 눈메꿈성이 떨어지는 문제가 있다.That is, according to the conventional method, while the veneer board is passed between the rollers installed up and down on the direct roll coater, the roller installed at the top is coated with the paint on the surface of the veneer so that a sufficient amount of paint is applied to the surface of the veneer at once. It is difficult to do so, there is a problem that the eyes are inferior when performing the snow work by the reverse roll coater.

이는 무늬목의 표면에 많은 양의 도료가 도포되어야만 리버스 롤러가 도포된 도료를 누르면서 무늬목의 눈매 및 목구로 충분히 밀어 넣어 눈메꿈 작업을 수행할 수 있음에도 불구하고 상기 다이렉트 롤 코터에서는 무늬목의 표면에 충분한 양의 도료를 한번에 도포하는 것이 불가능하기 때믄이다.Although a large amount of paint must be applied to the surface of the veneer, while the reverse roller can be applied to the eyeball and the neck of the veneer while pressing the paint applied, the direct roll coater has a sufficient amount on the surface of the veneer. This is because it is impossible to apply paint at once.

물론 상기와 같은 다이렉트 롤 코터에 의한 하도용 도료의 도포와 리버스 롤 코터에 의한 눈메꿈 작업을 수회 반복하면 원하는 수준의 눈메꿈 작업이 가능하지만, 이러한 경우 작업시간이 오래 걸려 생산성의 저하를 초래하게 된다.Of course, if the application of the paint for the undercoat by the direct roll coater and the eye work by the reverse roll coater are repeated several times, the desired level of eye work can be achieved. do.

또한 상기 종래의 방법은 다이렉트 롤 코터에 사용된 하도용 도료를 회수 할 수 없어 도료가 많이 소요되는 결점도 있다.In addition, the conventional method has a drawback in that the paint for the undercoating used in the direct roll coater cannot be recovered, which requires a lot of paint.

본 발명은 무늬목이 부착된 판재가 커튼 코터와 리버스 롤 코터를 통과하는 동안 무늬목의 눈메꿈 작업이 수행되도록 함으로서 한번에 양호한 눈메꿈 작업이 가능해지는 무늬목 판재의 도장방법을 제공하기 위한 것이다.An object of the present invention is to provide a method of painting veneer board material that enables good eye work at a time by allowing the eye wood work to be performed while the wood board with the wood veneer passes through the curtain coater and the reverse roll coater.

상기와 같은 목적을 달성하기 위한 본 발명의 실시예에 따라 판재의 표면에 접착된 무늬목을 센딩하는 단계와, 커튼 코터에 의해 무늬목의 표면에 하도용 도료를 도포하는 단계와, 리버스 롤 코터에 의해 무늬목 표면에 도포된 젖은 상태의 도료를 눌러 그레인으로 말어 넣음으로서 눈메꿈을 하는 단계와, 자외선에 의해 무늬목의 표면에 도포된 도료를 건조 경화시키는 단계와, 눈메꿈이 된 무늬목 위에 중도와 상도를 하는 공정으로 이루어진 무늬목 판재의 도장방법이 제공된다.Sending the veneer adhered to the surface of the plate according to an embodiment of the present invention for achieving the above object, the step of applying a coating material for the surface of the veneer by a curtain coater, by a reverse roll coater Applying the wet paint applied to the surface of the veneer and rolling it into the grain to dry the eyes, dry-hardening the paint applied to the surface of the veneer by ultraviolet rays, and the middle and top coats on the applied veneer Provided is a coating method of a veneer board made of a step.

본 발명의 방법에 따르면 무늬목 판재의 도장 시 무늬목의 눈메꿈 작업이 커튼 코터와 리버스 롤 코터에 의해 한번의 작업으로 이루어지기 때문에 생산성의 향상을 가져오게 되고, 커튼 코터에서는 사용된 도료를 회수하여 반복 사용하는 것이 가능하므로 도료의 절약과 이로 인한 원가의 절감을 가져오게 된다.According to the method of the present invention, when the veneer sheet is painted, the blinding operation of the veneer is performed by the curtain coater and the reverse roll coater in a single operation, and thus the productivity is improved, and the curtain coater recovers the used paint and repeats it. It is possible to use, which leads to saving of paint and thus cost.

도 2는 본 발명에 따른 무늬목 판재의 도장방법을 순차적으로 도시한 공정도로서, 본 발명은 무늬목의 표면을 센딩하는 단계와, 커튼 코터(Curtain Coater)에 의해 무늬목의 표면에 하도용 도료를 도포하는 단계와, 리버스 롤 코터에 의해 무늬목 표면에 도포된 젖은 상태의 도료를 눌러 그레인으로 말어 넣음으로서 눈메꿈을 하는 단계와, 자외선에 의해 무늬목의 표면에 도포된 도료를 건조 경화시키는 단계와, 눈메꿈이 된 무늬목 위에 중도와 상도를 하는 공정으로 이루어진다.Figure 2 is a process diagram sequentially showing the coating method of the veneer board according to the present invention, the present invention is the step of the step of the surface of the veneer, and the coater (Curtain Coater) to apply the paint for the coating on the surface of the veneer Steps to dry eyes by pressing the wet paint applied to the surface of the veneer by a reverse roll coater and rolling it into the grain; and drying and curing the coating applied to the surface of the veneer by ultraviolet rays; This is done by the process of the middle and top coat on the veneer.

상기에서 무늬목의 센딩은 무늬목 표면의 거친 부분을 페이퍼 등으로 연마하는 공정이다.Sending the veneer in the above is a process of polishing the rough surface of the veneer surface with a paper or the like.

상기 커튼 코터는 도료를 커튼막과 같은 형태로 하방으로 흘리면서 피도물의 표면에 도료를 도포하는 장비로서, 도료가 커튼막과 같은 형태로 하방으로 흘러내리면서 도포되므로 판재가 커튼 코터를 통과하는 동안 무늬목의 표면에 많은 양의 도료를 도포하는 것이 가능해진다.The curtain coater is a device for applying the paint to the surface of the coating while flowing the paint downward in the form of a curtain film, the coating is applied while flowing down downward in the form of a curtain film, so that the veneer while passing through the curtain coater It is possible to apply a large amount of paint to the surface of the.

상기 커튼 코터에 의해 표면에 많은 양의 도료가 도포된 판재는 리버스 롤 코터로 이송되고 이 리버스 롤 코터에 의해 무늬목의 표면에 도포된 도료가 젖은 상태로 눌려지면서 무늬목의 눈메와 목구로 밀려들어가는 눈메꿈 작업이 이루어지는데, 상기와 같이 커튼 코터에 의해 무늬목의 표면에 많은 양의 도료가 도포된 상태의 판재가 리버스 롤 코터로 이송되어 오기 때문에 리버스 롤 코터에서의 눈메꿈 작업이 한번에 만족할만한 수준으로 이루어지게 되는 것이다.The plate coated with a large amount of paint on the surface by the curtain coater is transferred to the reverse roll coater, and the paint applied to the surface of the veneer is pressed in the wet state by the reverse roll coater, and the eyes are pushed into the eyes and the neck of the veneer. As the above-mentioned work is done, the sheet is applied to the reverse roll coater with a large amount of paint applied to the surface of the veneer by the curtain coater as described above. Will be done.

또한 상기 커튼 코터는 커튼 형태로 흘러내린 도료를 회수하여 순환시키면서 반복적으로 사용하는 구조로 되어 있기 때문에 다이렉트 롤 코터를 사용하는 종래 방법에 비해 도료를 절감할 수 있게 된다.In addition, the curtain coater has a structure that is repeatedly used while recovering and circulating the paint flowed down in the form of a curtain it is possible to reduce the paint compared to the conventional method using a direct roll coater.

상기 리버스 롤 코터에서 눈메꿈이 된 판재는 다음 공정으로 이송되어 무늬목의 표면에 도포된 도료가 자외선에 의해 건조 경화되고, 이후 무늬목 위에 중도와 상도를 하여 제품을 얻는다. The sheet made of snow in the reverse roll coater is transferred to the next process so that the paint applied to the surface of the veneer is dried and cured by ultraviolet rays, and then the product is obtained by applying a middle and top coat on the veneer.
