본 발명은 착색 및 입체표면을 갖는 스테인레스 강판에 관한 것으로, 특히 미러 스테인레스(mirror stainless) 강판에 스트립핑면, 에칭면, 광택면, 금도금층을 조화있게 형성하여 착색과 어울리면서 입체효과를 갖게하는 스테인레스 강판과 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stainless steel sheet having a colored and three-dimensional surface. In particular, a stainless steel sheet having a three-dimensional effect in harmony with coloring by forming a stripping surface, an etching surface, a glossy surface, and a gold plated layer on a mirror stainless steel sheet in harmony. And to a method of manufacturing the same.
현재 엘리베이터의 의장품으로 사용디는 스테인레스 강판의 표면에 도장, 실크스크린, 에칭 등의 기술을 이용하여 다양한 무늬 및 모양을 표출하고 있는데, 이중 에칭(etching) 기술이 가장 널리 적용되고 있다.Currently, as a design of elevators, various patterns and shapes are expressed on the surface of the stainless steel sheet using techniques such as painting, silk screen, and etching, and the double etching technique is most widely applied.
에칭기술은 제1도와 같은 공정으로 이루어지는데, 그 과정을 살펴보면 다음과 같다.The etching technique consists of a process as shown in FIG. 1 and the process is as follows.
(a)와 같은 흑백필름 원고를 (b)와 같이 실크스크린망(1)의 전면에 네가티브(Negative) 감광액이 균일하게 도포된 망틀(2)을 갖는 실크스크린망(1)상에 올려 놓고 압력을 가해 밀착시켜 노광한 다음 흑백필름 원고를 걷어낸다.The black-and-white film manuscript as shown in (a) is placed on a silk screen mesh (1) having a mantle (2) coated with a negative photoresist uniformly on the front of the silk screen mesh (1) as shown in (b). To close and expose the black-and-white film originals.
그후, 실크스크린망을 수세하면 광선을 받지 못해 용해되어 감광막이 제거되는 부분(3)과, 광선을 받아 감광막이 경화된 부분(4)을 갖는 실크스크린망을 얻게 된다,Subsequently, washing the silk screen net to obtain a silk screen net having a portion (3) in which the photosensitive film is removed by dissolution due to no light and a portion (4) where the photosensitive film is cured by receiving the light,
이와 같이 제조된 실크스크린망을 스테인레스 강판에 올려 놓고 아크릴 우레탄계 수지잉크를 전면에 도포한 후 실크스크린망을 제거하면 (c)와 같이 스테인레스 강판에 잉크가 마스킹된 면(5)과, 마스킹된지 않는 면(6)이 형성된다.When the silk screen net thus prepared is placed on a stainless steel sheet and the acrylic urethane resin ink is applied to the entire surface, and then the silk screen net is removed, the surface (5) on which the ink is masked on the stainless steel sheet as shown in (c), and is not masked. Face 6 is formed.
이어서 이 염화 제2철에 적하하면 마스킹되지 않은면(6)이 에칭되며, 그후 이를 건조, 탈막, 수세, 중화 등의 공정을 거침에 따라 (d)와 광택면(mirror)을 갖는 스테인레스 강판 소재에 무광택면을 갖는 에칭부(7)가 형성된다.Subsequently, when dropping on the ferric chloride, the unmasked surface 6 is etched, and then, as a result of drying, film removal, washing with water, neutralizing, etc., a stainless steel sheet having (d) and a polished surface (mirror). The etching part 7 which has a matte surface is formed in it.
그러나 이와 같이 화학부식만으로 1차원적인 깊이의 단차를 갖게 한 경우는 입체감의 표현에 한계를 갖는다.However, when the chemical corrosion alone has a one-dimensional depth step, the three-dimensional expression is limited.
또한, 상기 부식면에 이물질 등이 부착될 경우에는 부착된 이물질의 제거가 용이치 않게 되므로 오히려 의장효과를 저하시키게 된다.In addition, when foreign matters are attached to the corrosion surface, the removal of the attached foreign matters is not easy, but rather reduces the design effect.
본 발명은 종래와는 달리, 미러 스테인레스 강판에 스트립핑(Stripping)공정, 에칭공정, 금도금층 형성공정, 필요에 따라 금변색 공정을 복합적으로 행하여 착시 효과의 입체감을 갖는 스테인레스 강판을 얻고자 하는데 그 목적이 있다.Unlike the related art, the present invention seeks to obtain a stainless steel sheet having a three-dimensional effect of optical illusion by performing a combination of a stripping process, an etching process, a gold plating layer forming process, and a gold discoloration process on a mirror stainless steel sheet as necessary. There is a purpose.
이하, 본 발명을 설명한다.Hereinafter, the present invention will be described.
본 발명은 미러 스테인레스(mirror stainless)강판 표면에 광택면과 스트립핑(stripping)면이 일부 형성되고, 나머지 부위는 에칭면이 형성된다.In the present invention, the surface of the mirror stainless steel (mirror stainless steel) is partially formed on the surface of the gloss and stripping (stripping), the rest of the etching surface is formed.
그리고 금도금층이 상기한 에칭면의 일부와, 광택면 일부의 부분에 형성되는 등 착색 및 입체표면을 갖는 스테인레스 강판으로 이루어진다.The gold plated layer is formed of a stainless steel sheet having a colored and three-dimensional surface, such as being formed on a part of the etching surface and a part of the glossy surface.
상기 스테인레스 강판의 표면에 금도금층을 형성함에 있어서는 광택면에도 할 수 있으나, 금도금층을 형성하고자 하는 광택면의 일부분을 에칭한 후 에칭면과, 광택면에 금도금층을 형성하면 광택면에만 금도금층을 형성한 것과는 달리 에칭에 따른 무광택면에도 금도금층이 형성되므로 에칭면(무광택면)에 형성된 금도금층이 광택면의 금도금층과 어울리면서 착시효과를 나타내게 된다.When forming a gold plated layer on the surface of the stainless steel sheet may be on the polished surface, but after etching a part of the polished surface to form a gold plated layer, if the gold plated layer is formed on the etched surface and the polished surface, only the gold plated layer Unlike forming a gold plated layer is formed on the matte surface due to the etching, so the gold plated layer formed on the etching surface (matte surface) is matched with the gold plated layer of the glossy surface to exhibit an optical illusion effect.
뿐만 아니라 상기한 금도금층의 형성후 이를 전해수용액에서 전해처리로 변색시킴에 따라 금도금층이 금의 고유색깔인 황색과 변색에 따른 갈색 또는 녹색과 어울려 다양한 색깔을 표출하게 된다.In addition, after the formation of the gold plated layer is changed to the electrolytic treatment in the electrolytic solution, the gold plated layer will display a variety of colors by matching with the yellow or brown or green due to the discoloration of gold.
제2도는 본 발명의 실시예를 나타낸 제조공정도로써, 첨부된 도면을 참고하여 구체적으로 설명한다.2 is a manufacturing process diagram showing an embodiment of the present invention, with reference to the accompanying drawings will be described in detail.
본 실시예는 하나의 패턴만을 예시하였으나, 그 패턴은 임의로 선택할 수 있는 바 이에 국한하지 않는다.Although the present embodiment exemplifies only one pattern, the pattern is not limited to that which can be arbitrarily selected.
(a)와 와 같은 영상패턴이 상이한 4종의 필름원고(A)(B)(C)(D)를 감광액이 전면에 균일도포된 실크스크린망(이때 실크스크린망은 긴장되게 망틀에 지지된다)에 올려 놓고 노광밀착기를 이용한, 밀착한 다음 노광 및 수세한다.Four types of film manuscripts (A) (B) (C) (D) with different image patterns such as (a) are applied to the silk screen net where the photoresist is uniformly coated on the front surface. ), It adhere | attaches with an exposure closer, and it exposes and washes.
이에 따라 (b)와 같이 감광막이 제거된 부분(3)과, 경화된 부분(4)을 갖는 각각의 실크스크린망(A')(B')(C')(D')을 얻게 된다.As a result, each silk screen net A '(B') (C ') (D') having a portion 3 having the photoresist film removed thereon and a cured portion 4 as shown in (b) is obtained.
이와 같이 실크스크린망이 완성되면 준비된 미러 스테인레스(mirror stainless) 강판에, 먼저 하나의 실크스크린망(A')을 올려 놓는다.When the silk screen net is completed as described above, one silk screen net (A ') is placed on the prepared mirror stainless steel (mirror stainless) steel sheet.
그후, 전면에 내산잉크를 마스킹한 후, 실크스크린망(A')을 제거하면 미러 스테인레스 강판의 표면에 (c)의 (A)와 같이 마스킹된면(5)과, 마스킹되지 않은 면(6)이 형성된다.Then, after masking the acid-resistant ink on the front surface, the silk screen net (A ') is removed, and the masked surface (5) and the unmasked surface (6) on the surface of the mirror stainless steel sheet (6). ) Is formed.
상기한 공정(A)을 거친 강판을 전해탱크에서 스트립핑(stripping) 처리한다.The steel sheet subjected to the above step (A) is stripped in an electrolytic tank.
이때 전해탱크내에 담겨진 수용액은 황산 10-40%, 질산 5-25%이고 나머지는 물로 이루어지며, 양극은 Pd(납)판으로 하고 음극은 소재인 스테인레스 강판으로 하여, 전류밀도 10-40A/m2에서 수십초에서 수분동안 전해처리하므로써 스트립핑이 완료된다.At this time, the aqueous solution contained in the electrolytic tank is 10-40% sulfuric acid, 5-25% nitric acid and the remainder is made of water. The anode is made of Pd (lead) plate and the cathode is made of stainless steel plate, and the current density is 10-40A / m. Stripping is completed by electrolysis for 2 to several tens of seconds.
그후, 스트립핑된 스테인레스 강판을 전해탱크에서 꺼내어 수세, 건조 등을 거침에 따라 마스킹된 내산잉크가 탈막되어 (A')와 같이 광택면(8)을 갖는 스테인레스 강판에 반광택면을 갖는 스트립핑면(9)이 형성된다.After that, the stripped stainless steel sheet was removed from the electrolytic tank and washed with water, dried, and the like, and the masked acid-resistant ink was removed, thereby stripping the surface having a semi-gloss surface on the stainless steel sheet having the glossy surface 8 as shown in (A '). (9) is formed.
상기한 스트립핑 공정은 스테인레스 강판의 광택면 일부를 걷어내어 반광택표면을 갖게 하는 것이다.The stripping process is to remove part of the glossy surface of the stainless steel sheet to have a semi-gloss surface.
상기 스트립핑공정을 거친 스테인레스강판(A')을 1차 에칭하는데, 이때 1차 에칭은 스테인레스강판(A')에 (b)의 (B')에 도시한 실크스크린망을 올려 놓고 전면에 내산잉크를 마스킹한 후 실크스크린망(B')을 걷어낸다.The stainless steel sheet A 'subjected to the stripping process is first etched, and the primary etching is performed by placing the silk screen net shown in (B') of (b) on the stainless steel sheet A 'and putting it on the front surface. After masking the ink, the silk screen net (B ') is removed.
이에 따라 스테인레스 강판의 표면에 (d)의 (B)와 같이 마스킹면(5)과, 마스킹되지 않은 면(6)이 형성된다.Thereby, the masking surface 5 and the unmasked surface 6 are formed in the surface of a stainless steel plate like (B) of (d).
그후, 마스킹되지 않은 면(6)을 공지의 에칭방법으로 에칭한 후, 내산잉크를 탈막하면 (B')와 같이 에칭된 면(10)과, 스트립핑면(9) 그리고 광택면(8)(8a)이 표출된다.Thereafter, the unmasked surface 6 is etched by a known etching method, and when the acid resistant ink is removed, the etched surface 10, the stripping surface 9 and the glossy surface 8 ( 8a) is expressed.
이어서 상기한 (B')의 스테인레스 강판 상면에 (b)의 (C')와 같은 실크스크린망을 올려 놓고 내산잉크로 전면을 마스킹한 후 실크스크린망(C')을 걷어내면 (e)의 (C)와 같은 마스킹면(5)(5a)과, 마스킹 안된 면(6)이 형성된다.Subsequently, a silk screen net such as (C ') of (b) is placed on the upper surface of the stainless steel plate of (B'), masked the entire surface with an acid resistant ink, and then the silk screen net (C ') is rolled out. The masking surface 5 (5a) similar to (C) and the unmasked surface 6 are formed.
그리고 (C)강판을 공지의 에칭방법으로 2차 에칭하고 내산잉크를 탈막하면 (C')와 같이 광택면(8a)상에 에칭면(11)(11a)이 형성된다.When the (C) steel sheet is secondarily etched by a known etching method and the acid resistant ink is removed, etching surfaces 11 and 11a are formed on the glossy surface 8a as shown in (C ').
상기한 2차 에칭은 여기에 금도금층을 형성하기 위한 전단계이다.The secondary etching described above is a preliminary step for forming the gold plated layer therein.
이어서 (C')의 스테인레스 강판 상면에 (b)의 (D')와 같은 실크스크린망을 올려놓고 내산잉크로 전면을 마스킹한 다음 실크스크린망(D')을 걷어내면 (f)의 (D)와 같은 상태가 된다.Subsequently, a silk screen net such as (D ') of (b) is placed on the upper surface of the stainless steel plate of (C'), and the entire surface is masked with an acid resistant ink, and then the silk screen net (D ') is rolled out. ) Will be in the same state.
이러한 상태에서 광택면(8a)N과 에칭면(11)(11a)에 금도금을 실시하여 금도금층을 형성한 다음 마스킹된 내산잉크를 탈막하여 (g)와 같은 완성품을 얻게 된다.In this state, gold plating is performed on the polished surface 8a and the etching surfaces 11 and 11a to form a gold plated layer, and then the masked acid resistant ink is removed to obtain a finished product as shown in (g).
상기한 공정을 거쳐 얻어지는 금도금층(12)은 무광택을 갖는 에칭면(11)(11')과, 광택면(8a)으로 이루어지게 된다.The gold plated layer 12 obtained through the above process is composed of an etching surface 11 (11 ') having a matt and a glossy surface 8a.
따라서 금색의 광택차이로 서로 상이한 표면시각 효과를 갖게 된다.Therefore, the difference in surface visual effects is achieved by the difference in gloss of gold.
또한, 본 발명은 필요에 따라 금도금층(12)의 색상을 다양하게 변화시킬 수 있는데, 이때는 금도금층(12)만을 남기고 타부분은 실크스크린망(D')을 이용하여 마스킹한후 이를 CrO3, 황산, 인산, 등의 전해수용액에서 전해처리하면 금색상(황색)이 변화되어 (금색의 변색은 갈색계열의 gradation 단계를 나타냄) 갈색, 또는 녹색과 어울리게 되므로 다양한 색상을 띄게 된다.In addition, the present invention can vary the color of the gold plated layer 12 as needed, in this case, leaving only the gold plated layer 12 and the other part is masked using a silk screen net (D ') and then CrO 3 When electrolytic treatment is carried out in an electrolytic solution of sulfuric acid, phosphoric acid, etc., the color of gold (yellow) is changed (gold discoloration represents the gradation stage of brown series), so it becomes diverse with brown or green color.
제3도는 스트립핑공정을 거침에 따라 형성된 스트립핑면(9)을 확대하여 나타낸 단면도이고, 제4도는 미러 스테인레스 강판의 표면을 에칭한 에칭면(10)을 나타낸 것이다.3 is an enlarged cross-sectional view of the stripping surface 9 formed through the stripping process, and FIG. 4 is an etching surface 10 in which the surface of the mirror stainless steel sheet is etched.
상기한 도면에 나타난 바와 같이 스트립핑에 따라 얇게 표면을 뜯어낸 부분과, 에칭에 의한 다소 깊은 식각에 따라 동일면상에서 그 깊이의 단차가 발생됨은 물론 에칭면(10)은 무광택인데 반해, 스트립핑면(9)은 반광택으로 나타나게 되므로 착시효과를 갖게 된다.As shown in the drawings, the step of thinly peeling off the surface according to the stripping and the step of the depth is generated on the same surface due to the somewhat deep etching by etching, as well as the etching surface 10 is matt, whereas the stripping surface ( 9) appears to be semi-gloss, so it has an optical illusion effect.
이상에서 완성된 본 발명은 (g)와 같이, 스트립핑면(9)에 따른 반광택면(13), 표면의 에칭(10)에 따른 무광택면(14), 공정이 수반되지 않은 미러(mirror) 상태의 광택면(8), 에칭면(11)(11a)과 광택면(8a)에 도금된 금도금층(12)이 복합적으로 형성됨에 따라 단차깊이 및 여러형태의 광택무늬가 한데 어우러져 착시효과의 극치를 나타내게 된다.The present invention completed as described above (g), the semi-gloss surface 13 according to the stripping surface 9, the matte surface 14 according to the etching (10) of the surface, the mirror without the process As the polished surface 8, the etching surface 11, 11a and the gold plated layer 12 plated on the glossy surface 8a are formed in a complex state, step depth and various types of glossy patterns are combined to provide an optical illusion effect. Extreme values will be shown.
상기한 제2도는 단순한 형태의 실시예만을 예시하였으나, 필름의 영상무늬를 여러 형태로 함은 물론 상기한 단순배열이 아닌 입체적인 배열을 비롯하여 이들의 패턴이 겹치도록 하여 상기 공정을 수행하면 한폭의 풍경화를 연상할 수 있는 다양한 형태의 표면 효과를 얻게 된다.Although FIG. 2 illustrates only an embodiment of a simple form, the image pattern of the film is not only in various forms, but also the three-dimensional arrangement including the three-dimensional arrangement, not the simple arrangement described above, and the pattern is overlapped to perform the landscape. You can get a variety of surface effects that can be associated with.
