본 발명은 자동차외부흠집의 부분도장방법에 관한 것으로, 특히 도장부위의 범위가 적고 도장부위의 가장자리가 기존도막층에 대하여 윤곽의 형태로 나타나지 않도록한 자동차, 특히 승용자동차 외부흠집의 부분도장방법에 관한 것이다.The present invention relates to a partial coating method of the exterior scratch of the automobile, and in particular, to a partial coating method of the exterior scratch of a vehicle, in particular a passenger vehicle, in which the range of the painted portion is small and the edge of the painted portion does not appear in the form of a contour with respect to the existing coating layer. It is about.
일반적으로 자동차, 예를 들어 승용차의 도장에 있어서는 전체외면을 도장하는 전도장, 판넬단위를 도장하는 구분도장과, 승용차외부판넬의 일부분에 생긴 흠집을 도장하는 부분도장이 있다. 본 발명은 외부판넬의 일부분에 생긴 흠집을 도장하는 부분도장에 관련된 것이다.In general, in the coating of automobiles, for example, passenger cars, there are conductive coatings for coating the entire outer surface, division coatings for coating the panel unit, and partial coatings for scratches on a portion of the outer panel of the vehicle. The present invention relates to a partial coating for painting scratches on a portion of the outer panel.
종래기술의 부분도장방법에 있어서는 판넬의 한 부분에 나타난 일반적으로 요입형의 흠집에 퍼티(putty)와 같은 흠집충전제를 충전하고, 흠집부위를 방청하고 살오름성을 보이도록 하는 초벌도료(prime sufacser)를 도포한 다음 초벌도료층의 표면을 연마하여, 초벌도료층상에 색상도료를 도포하고 그 위에 상도도료인 투명도료를 도포한 후 투명도료층을 투명도료에 용제를 첨가한 투명도료브랜딩제를 도포하여 브랜딩처리하며 최종적으로 공택처리하는 과정으로 수행되고 있다. 제1도∼제3도를 참조하여 전형적인 종랙기술의 부분도장과정설명키로 한다. 제1도(A∼F)는 이러한 종래기술의 부분도장과정을 보인 것으로, 제1도(A)에서는 승용차의 어느한 외부판넬(1)에 일반적으로 요입형으로 나타나는 흠집(2)이 있는 것으로 보이고 있다. 도면에서 이러한 흠집(2)은 이해를 돕기 위하여 고장되게 표현하였다. 이러한 흠집(2)은 일반적으로 요입형이거나 이에 가까운 형태이고 평면에서 보았을 때에는 다양한 형태를 보일 것이다. 도면에서는 설명을 간편히 하기 위하여 원형인 것으로 도시하였다. 외부판넬(1)의 흠집(2)을 부분도장하는 첫번째 과정은 퍼티와 같은 흠집충전제(3)를 흠집(2)에 충전하는 것이다. 흠집충전제(3)가 충전된 부위에는 흠집(2)의 주위를 방청하고 흠집(2)부위가 살올름성을 보이도록 초벌도료를 도포하여 초벌도료층(4)을 형성한다. 도면에서 초벌도료층(4)은 중앙이 볼록한 볼록렌즈형으로 표현되어 있으나 실제로 이러한 초벌도료층(4)은 박막도층의 형태이며, 도면에서는 이러한 초벌도료층(4)의 가장자리가 흠집(2)의 주위에서 극히 얇은 점층부를 형성하고 있음을 설명하기 위하여 중앙이 볼록한 형태로 표현하였다. 이후에, 초벌도료층(4)의 표면은 번수400∼600의 샌드페이퍼를 이용하여 연마처리되어 상도부착성을 향상시키고 초벌도료층(4) 표면의 미세홈을 제거한다(제1도 D 참조). 표면연마된 초벌도료층(4)의 표면에는 스프레이건을 이용하여 색상도료가 도층되어 색상도료층(5)이 도층된다. 이러한 색상도료층(5)의 가장자리는 초벌도료층(4)의 범위를 약간 넘어선 범위까지 확대되며 색상도료의 색상은 흠집(2)이 생긴 외부판넬(1)의 기존도막의 색상과 일치하는 색상이다. 이어서, 색상 도료층(5)상에 투명도료층(6)이 형성되고 이 투명도료(6)은 이에 사용된 투명도료에 100∼200%의 용제를 혼합한 투명도료부랜딩제를 이용하여 브랜딩 처리된다.In the conventional method of partial coating, the primer sufacser is filled with a filler, such as a putty, on a generally indented scratch on the panel, and prevents the scratch and shows salvage. ), And then polish the surface of the primary paint layer, apply a color paint on the primary paint layer, apply a transparent paint, which is a top coat, and then apply the transparent paint branding agent with the transparent paint layer added to the transparent paint. It is applied to the process of coating, branding and finally public treatment. With reference to FIGS. 1 to 3, a partial coating process description of a typical vertical rack technique will be described. 1A to F show a partial coating process of the prior art, and in FIG. 1A, there is a scratch 2 that is generally indented on an outer panel 1 of a car. It is showing. In the drawings, such scratches 2 are shown to be broken for better understanding. These scratches 2 are generally concave or near and will show a variety of shapes when viewed in plan. The drawings are shown as being circular for simplicity of explanation. The first process of partially painting the scratches 2 of the outer panel 1 is to fill the scratches 2 with a scratch filler 3 such as a putty. The area filled with the scratch filler 3 is rusted around the scratches 2, and the primary paint layer 4 is formed by applying a primary paint so that the scratches 2 show salvability. In the drawing, the primary paint layer 4 is represented by a convex lens type with a convex center, but in practice, the primary paint layer 4 is in the form of a thin film layer, and in the drawing, the edges of the primary paint layer 4 are scratched (2). In order to explain the formation of an extremely thin viscous layer around the center, it is expressed in a convex form. Subsequently, the surface of the primary paint layer 4 is polished using sandpaper having a number of 400 to 600 to improve top coat adhesion and to remove microgrooves on the surface of the primary paint layer 4 (see FIG. 1D). . On the surface of the surface-polished primary paint layer 4, a color paint is coated using a spray gun, and the color paint layer 5 is coated. The edge of the color paint layer 5 extends to a range slightly beyond the range of the primary paint layer 4, and the color of the color paint matches the color of the existing paint of the outer panel 1 where the scratches 2 are formed. to be. Subsequently, a transparent paint layer 6 is formed on the color paint layer 5, and the transparent paint 6 is branded using a transparent paint sub-landing agent mixed with 100 to 200% of a solvent in the transparent paint used therein. Is processed.
그러나, 종래기술의 이러한 부분도장방법에 있어서는 브랜딩처리부위에 나타나는 페인트더스트와 오렌지필(orange peel) (도막이 고루지 못하고 귤껍질모양으로 울퉁불퉁한 상태)이 도막건조후 컴파운드연마제로 연마하여 없앨 수는 있다. 최종처리과정으로 브랜딩 처리된 부분을 광택처리시에 투명브랜딩처리부분, 특히 투명도료층(6)을 포함하는 색상도료층(6)의 가장자리부부은 부착력이 약하여 박리현상이 일어나거나 흠집주위의 기존도막층과의 사이에 단차이가 나타날 수 있다. 이때에 기존도막층상의 투명도료층의 단차이가 난 턱부분에서는 빛이 다른 방향으로 굴적되어 가장자리부위에 윤곽이 나타나게 된다. 또한 색상도료층(5)을 도충하는 과정에서는 그 도층범위를 정확히 한정하기 어려워 예상범위가 필요이상 확대된 상태에서 색상도료가 도층될 수 밖에 없다.However, in this partial coating method of the prior art, the paint dust and orange peel (uneven coating and unevenness of orange peel) appearing on the branded portion can be removed by polishing with a compound polishing agent after drying the coating. have. When the branded portion is polished in the final process, the transparent branding portion, in particular, the edge portion of the color paint layer 6 including the transparent paint layer 6 has weak adhesive force, causing peeling phenomenon or existing coating film around the scratches. Differences may appear between layers. At this time, in the jaw portion of the transparent paint layer on the existing coating layer, light is accumulated in different directions, so that the outline appears at the edge portion. In addition, in the process of plunging the color paint layer 5, it is difficult to precisely limit the layer range, and the color paint is inevitably coated in a state in which the expected range is enlarged more than necessary.
본 발명에 있어서는 종래의 이와같은 점을 감안하여 창안한 것으로, 초벌도료층을 미세연마하고 색상도료층은 색상도료의 도포범위를 리버스마스킹으로 한정하여 1차도포하고 이러한 1차색상도료층을 다시 미세연마 후 2차색상도료를 브랜딩도장하는 과정을 도입하므로서 색상도료층의 가장자리에서 윤곽이 나타나지 않도록함과 동시에 색상도료층이 필요이상 확대되지 않도록한 것인바, 이를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention, invented in view of such a conventional point, the fine coating layer is finely polished, and the color coating layer is applied firstly by limiting the application range of the color coating to reverse masking, and again applying the primary color coating layer. By introducing the process of branding coating of secondary color paint after micropolishing, the contour of the color paint layer is prevented from appearing and the color paint layer is not enlarged more than necessary. This will be described in more detail based on the accompanying drawings. Is as follows.
제4도(A∼H)는 본 발명의 방법에 따른 도장과정을 설명하고 있는 것으로, 제1도에 관련하여 설명된 종래기술의 경우와 같이 도면을 다분히 과정적이고 설명적으로 표현하였다.4A to 4H illustrate a painting process according to the method of the present invention, and as in the case of the related art described with reference to FIG.
제4도(A)에서 외부판넬(10)의 흠집(12)내에 퍼티와 같은 흠집충전제(14)가 충전되고 그 위에 초벌도료층(16)이 도층된다. 이러한 초벌오료층(16)은 통상적인 방법으로 연마된다. 특 번수 600∼800의 샌드페이퍼를 이용하여 수샌딩연마된다. 이후에 연마된 초벌도료층(16)상에 색상도료가 1차도층된다. 이때에 색상도료의 확산을 방지하기 위하여 리버스마스크(18)을 이용하여 마스킹한 후 색상도료를 도층하여 1차색상도료층(20)을 형성한다. 다음으로 리버스마스크(18)를 제거하고 1차색상도료층(20)과 그 주변을 변수 800∼1000의 샌드페이퍼를 이용하여 수샌딩연마된다. 이때의 연마정도는 초벌도료층(16)이 드러나지 않을 정도로 제한하는 것이 좋다. 이와같은 1차색상도료층(20)의 연마후에 이러한 1차새상도료층(20)을 형성하는데 사용된 색상도료에 10∼20%의 부피비로 용제를 혼합하여 2차 색상도료의 도층과 브랜딩처리를 동시에 수행토록한다. 이로써 2차색상도료층(22)이 형성되고 이 과정에서 색상도료의 브랜딩처리가 이루어져 가장자리의 색얼룩이 방지된다. 2차색상도료의 브랜딩처리로 1차색상도료층(20)의 연마홈이 제거되고 색상도료가 메탈릭입자를 포함하는 것인 경우 이들 메탈릭입자가 불규칙하게 배열되어 색얼룩현상이 두드러지게 하거나 윤곽으로 나타나게 되는 가장자리부분이 브랜딩처리되어 제거된다. 이후 투명도료층(24)이 도층되고 투명도료브랜딩처리되는 통상적인 과정(제4도의 G, H)이 수행된다.In FIG. 4 (A), a scratch filler 14 such as a putty is filled in the scratches 12 of the outer panel 10, and the primary paint layer 16 is coated thereon. This primary fertilizer layer 16 is polished in a conventional manner. It is sand sanded using sand paper with a special number of 600 to 800. Subsequently, the primary color of the color paint is polished on the primary paint layer 16 polished. At this time, in order to prevent the spread of the color paint masking using the reverse mask 18, and then the color paint layer to form a primary color paint layer (20). Next, the reverse mask 18 is removed, and the primary color paint layer 20 and the surroundings thereof are sand sanded using sandpaper having a variable of 800 to 1000. At this time, the degree of polishing is preferably limited so as not to reveal the primary paint layer (16). After polishing of the primary color paint layer 20, the solvent is mixed with the color paint used to form the primary new paint layer 20 in a volume ratio of 10 to 20%, and the coating and branding treatment of the secondary color paint is performed. To run simultaneously. As a result, the secondary color paint layer 22 is formed, and in this process, the color paint is branded to prevent color smudges at the edges. If the polishing groove of the primary color paint layer 20 is removed by the second color paint branding process and the color paint contains metallic particles, these metallic particles are irregularly arranged to make the color spots stand out or contour. The edges that appear are branded and removed. Thereafter, the usual process (G, H of FIG. 4) is performed in which the transparent paint layer 24 is coated and the transparent paint branding is performed.
이와같은 본 발명은 1차색상도료층(20)이 도층된 후 미세연마되고 2차색상도료의 도층과 브랜딩처리되는 것이 종래 기술에 대하여 특징이 있는 것이다. 1차색상도료층(20)은 추후 시행되는 2차색상도료의 도층과 브랜딩처리과정에 의하여 그 도층범위를 필요 이상 확대할 필요가 없으며 가장자리부분에서 나타나는 단차이나 색의 얼룩이 2차색상도료의 도층과 브랜딩처리후 형성되는 2차색상도료층(22)에 의하여 제거된다. 투명도장층(24)의 형성과 그 브랜딩처리과정은 종래기술에 따르므로 이에 대한 설명은 생략키로 한다.The present invention is characterized by the prior art that the primary color paint layer 20 is finely ground and then branded with the coating layer of the secondary color paint. The primary color paint layer 20 does not need to enlarge the coating range more than necessary by the coating process and the branding process of the secondary color paint which will be performed later. And by the secondary color paint layer 22 formed after the branding treatment. Since the transparent coating layer 24 is formed and its branding process is according to the prior art, description thereof will be omitted.
