이하 본 발명에 의한 고품 느낌의 동판 안내판 및 그 제작방법에 대하여 상세히 설명한다.Hereinafter, the copper plate guide plate of the high-quality impression according to the present invention and a manufacturing method thereof will be described in detail.

도 1은 본 발명에 의한 동판 제조 단계를 도시한 공정도이고, 도 2는 본 발명에 의해 가공된 동판의 단면도이며, 도 3은 본 발명에 의한 안내판의 사시도이다.1 is a process chart showing the copper plate manufacturing step according to the present invention, Figure 2 is a cross-sectional view of the copper plate processed by the present invention, Figure 3 is a perspective view of the guide plate according to the present invention.

본 발명에 의한 고품 느낌의 동판 안내판의 제작방법은 도 1에 도시한 바와 같이 용접단계, 스크래칭 단계, 에칭 단계, 산화발색 단계, 표면 도장 단계, 제1열처리 단계, 충전 단계 및 제2열처리 단계로 구성된다.The manufacturing method of the high quality copper plate guide plate according to the present invention is as shown in Figure 1 welding step, scratching step, etching step, oxidation coloration step, surface coating step, the first heat treatment step, the filling step and the second heat treatment step It is composed.

우선, 1.5~2.0㎜ 두께의 동판(110)을 절단 및 절곡 성형하고, 이를 용접하여 안내판의 형상을 제조하는 용접단계를 실시한다. 일반적으로 동판(110)을 용접할 때 동판(110)의 용접부위가 휘어지는 현상이 발생하는데, 이를 방지하기 위하여 동판(110)의 용접 접합부위를 충분히 예열한 후, 동-은(Cu-Ag)계열의 환봉을 가열하고 붕소를 묻힌 후 산소용접을 함으로써 동판(110)이 용접할 때 휘는 것을 방지하도록 한다.First, the copper plate 110 having a thickness of 1.5 to 2.0 mm is cut and bent, and a welding step of manufacturing the shape of the guide plate is performed by welding the copper plate 110. In general, when welding the copper plate 110, the welded portion of the copper plate 110 is bent, in order to prevent this, after sufficiently preheating the welded joint of the copper plate 110, Cu-Ag By heating the round bar of the series and buried boron oxygen welding to prevent the copper plate 110 is bent when welding.

상기와 같이 용접단계를 통해 동판(110)을 절단 및 굴곡하고 접합하여 안내판으로 가공한 후, 동판(110)의 표면을 스크래칭하는 스크래칭 단계를 실시한다.As described above, the copper plate 110 is cut, bent and bonded through a welding step, and then processed into a guide plate, and a scratching step of scratching the surface of the copper plate 110 is performed.

상기 스크래칭 단계는 동판(110) 표면의 먼지와 이물질을 제거하고, 용접단계를 거치며 동판(110)의 표면에 잔류하는 용접 이물질을 연마기로 제거하며, 고운 모래를 압축공기와 함께 동판(110)의 표면에 분사하여 표면에 잔류하는 이물질을 깨끗이 제거하고, 이후 동판(110)의 표면에 형성될 산화피막층이 더욱 잘 형성되도 록 한다.The scratching step removes dust and foreign matter from the surface of the copper plate 110, removes the welding foreign matter remaining on the surface of the copper plate 110 with a polishing machine through a welding step, and fine sand of the copper plate 110 together with compressed air. By spraying on the surface to remove the foreign matter remaining on the surface, and then to the oxide film to be formed on the surface of the copper plate 110 is better formed.

상기 스크래칭 단계를 통해 동판(110) 표면의 이물질이 제거된 안내판에 미리 준비된 디자인대로 그래픽 또는 문자의 형태대로 에칭(Etching)하여 안내판에 부식홈(150)을 형성하는 에칭단계를 실시한다. 에칭단계에서 사용되는 에칭액은 일반적으로 널리 사용되는 동판 에칭액을 사용한다.Through the scratching step, an etching step of forming a corrosion groove 150 in the guide plate is performed by etching (Getching) in the form of a graphic or a letter according to a design prepared in advance on the guide plate from which foreign substances on the surface of the copper plate 110 are removed. The etchant used in the etching step generally uses copper plate etchant which is widely used.

상기 에칭단계를 통해 부식홈(150)이 형성된 동판(110)을 산화부식시켜 부식층(120)을 형성함으로써 오래된 고품(古品)의 안내판 느낌이 들도록 하는 산화발색 단계를 실시한다.Through the etching step, the copper plate 110 in which the corrosion grooves 150 are formed is oxidized and corroded to form the corrosion layer 120.

산화발색 단계는 질산철(Fe(NO3)2·6H2O) 10~70중량%, 질산구리(Cu(NO3)2) 10~70중량% 및 유화가리(K2S) 10~70중량%를 혼합하여 준비하고, 상기 혼합된 혼합액 30~70중량%와 물 30~70중량%를 혼합하여 산화액을 준비한다. 상기와 같은 비율로 질산철, 질산구리, 유화가리 및 물을 혼합하여 구성한 산화액으로 동판(110)을 산화시켰을 때 오래된 동판의 색상과 가장 비슷하고 자연스럽게 동판(110)이 산화 부식되어 부식층(120)이 형성되는 것이다.Oxidation color development step is 10 to 70% by weight of iron nitrate (Fe (NO 3 ) 2 · 6H 2 O), 10 to 70% by weight of copper nitrate (Cu (NO 3 ) 2 ) and 10 ~ 70 emulsified glass (K 2 S) The mixture is prepared by mixing by weight%, 30 to 70% by weight of the mixed mixture and 30 to 70% by weight of water to prepare an oxidizing solution. When the copper plate 110 is oxidized with an oxidizing solution formed by mixing iron nitrate, copper nitrate, emulsified glass and water in the same ratio as described above, the copper plate 110 is most similar to the color of the old copper plate. ) Is formed.

그리고, 상기 산화액 및 동판(110)을 약 50~70℃의 온도까지 가열한 후, 동판(110)을 산화액에 담구어 동판(110) 표면을 산화시킨다. 이때, 동판(110)과 산화액을 50~70℃의 온도까지 가열하는 이유는 상기 온도에서 동판(110)과 산화액의 부식반응이 활성화되어 발색이 잘 이루어지기 때문이다. 바람직하게는 60℃의 온도로 산화액과 동판(110)을 가열하는 것이 부식반응을 활성화 시킨다.Then, after the oxidizing solution and the copper plate 110 is heated to a temperature of about 50 ~ 70 ℃, the copper plate 110 is immersed in the oxidizing solution to oxidize the surface of the copper plate 110. At this time, the reason for heating the copper plate 110 and the oxidizing solution to a temperature of 50 ~ 70 ℃ is because the corrosion reaction of the copper plate 110 and the oxidizing solution is activated at the above temperature is well formed. Preferably, heating the oxidation liquid and the copper plate 110 to a temperature of 60 ℃ to activate the corrosion reaction.

상기와 같이 동판(110)을 산화액에 담구면 동판(110)의 표면이 균일하게 갈색을 띄게 되는데, 이때, 수세미나 거친 천 등을 이용하여 표면을 불규칙하게 문지르면서 자연상태에서 부식이 일어난 느낌이 들도록 가공한다. 그리고, 동판(110)을 자연건조한 후, 동판(110)을 50~70℃로 가열하고 산화액을 스프레이 분사함으로써, 동판의 표면을 불균일하게 부식시켜 오랜 세월동안 자연에서 자연스럽게 부식된 것처럼 보이도록 한다.When the copper plate 110 is immersed in the oxidizing solution as described above, the surface of the copper plate 110 is uniformly browned. At this time, the surface of the copper plate 110 is rubbed with a scouring pad or a rough cloth, and the corrosion occurs in a natural state. It is processed to lift. Then, after the copper plate 110 is naturally dried, by heating the copper plate 110 to 50 ~ 70 ℃ and spray spraying the oxidizing solution, the surface of the copper plate is unevenly corroded to look as naturally corroded in nature for many years. .

상기 산화액을 이용하여 동판(110)을 부식시키면 동판(110)의 표면이 구리빛에서 갈색으로 부식되며 발색된다.When the copper plate 110 is corroded using the oxidizing solution, the surface of the copper plate 110 is corroded to brown and colored.

상기 산화발색 단계를 통해 동판(110)의 표면에 부식층(120)이 형성된 후에 표면도장 단계를 실시한다. After the corrosion layer 120 is formed on the surface of the copper plate 110 through the oxidation-coloration step, the surface coating step is performed.

표면도장 단계는 산화발색 단계를 통해 형성된 부식층(120)을 보호하기 위하여 우레탄계열의 무기질 도료를 동판의 표면에 도포함으로써, 부식층(120) 상부에 보호층(130)을 형성하는 것이다. 우레탄 계열의 도료는 열처리를 통해 상기 에칭단계를 통해 형성된 부식홈(150)에 충진되는 에나멜 페인트(140)와 산화발색된 부식층(120) 표면의 보호를 견고하게 하기 때문에 우레탄 계열의 도료를 사용하는 것이 바람직하다.The surface coating step is to form a protective layer 130 on the corrosion layer 120 by applying a urethane-based inorganic paint on the surface of the copper plate in order to protect the corrosion layer 120 formed through the oxidation-coloration step. The urethane-based paint uses a urethane-based paint because it hardens the protection of the enamel paint 140 and the oxide-colored corrosion layer 120 filled in the corrosion groove 150 formed through the etching step through heat treatment. It is preferable.

표면도장 단계를 통해 보호층(130)이 형성된 동판(110)을 120~140℃의 온도에서 40~60분 동안 가열하는 제1열처리 단계를 실시한다. 이러한 표면도장 단계를 통하여 보호층(130)이 동판(110)과 견고하게 결속하도록 하는 것이다. 상기 열처리 단계가 만일 140℃ 온도보다 높은 온도에 이루어지면 동판(110)에 열 변형이 발생 하게 되고, 120℃ 온도보다 낮으면 열처리가 제대로 이루어지지 않기 때문에 120~140℃의 온도범위에서 열처리를 하는 것이 바람직하다.The first heat treatment step of heating the copper plate 110 having the protective layer 130 formed through the surface coating step at a temperature of 120 to 140 ° C. for 40 to 60 minutes. Through the surface coating step, the protective layer 130 is to be firmly bound with the copper plate (110). If the heat treatment step is made at a temperature higher than 140 ℃ temperature heat deformation occurs in the copper plate 110, if lower than 120 ℃ temperature heat treatment is not performed properly because the heat treatment in the temperature range of 120 ~ 140 ℃ It is preferable.

When the paint 140 is filled in the corrosion groove 150, the paint 140 that is incorrectly painted outside the corrosion groove 150 may be wiped off using an enamel thinner. This is because the corrosion layer 120 may be wiped together.

상기와 같이 에나멜 신너로 페인트(140)를 닦아 낼때 보호층(130)의 강도가 에나멜 페인트보다 강하기 때문에 보호층(130)과 부식층(120)이 닦여나가지 않고 그대로 남아있게 되는 것이다.When the paint 140 is wiped with the enamel thinner as described above, since the strength of the protective layer 130 is stronger than that of the enamel paint, the protective layer 130 and the corrosion layer 120 remain without being wiped off.

상기의 충전단계를 거친 동판(110) 즉, 안내판을 120~140℃의 온도에서 40~60분간 가열하는 제2열처리 단계를 통하여 부식홈(150)에 충전된 페인트(140)가 부식홈(150)에 견고하게 부착 결속되도록 한다.The paint 140 filled in the erosion grooves 150 through the second heat treatment step of heating the copper plate 110, ie, the guide plate, for 40 to 60 minutes at a temperature of 120 to 140 ° C through the filling step is the erosion grooves 150. ) To be firmly attached.
