Description

Two tone painting method [

The present invention relates to a two-tone painting method of painting a uniform thickness while minimizing the use of a masking jig when painting a first colored area and a second colored area of a part by using first and second colors different from each other, The present invention relates to a multi-tone painting method for painting different colors on a plurality of divided surfaces.

As the aesthetic desires of people have increased in recent years, there is a tendency to emphasize color as well as the function of objects. Because color is a design element that can be changed easily and can maximize change, some people express their own personality and meet their aesthetic desires without being satisfied with the existing color of the object, but painted according to the symbol. In order to satisfy consumers' tastes, companies often make purchases by diversifying colors and patterns of products of the same type. There are also cases where paintings are made to give a texture coherence to a product composed of various materials. For example, in the case of automobiles, some materials made of plastic materials are painted to make them look like metal for light weight.

This trend has led to the development of techniques for coloring objects, and a variety of methods have been developed to paint two or more colors or patterns in addition to a method of painting a whole color in one color. Examples include masking tape and vinyl, laser, and masking jig, as well as a variety of shots and shots of different colors.

A typical method is to use a masking tape and a vinyl. The masking tape and the vinyl are used to cover the unpigmented surface as shown in FIG. 1A, and then the remaining exposed surface is painted. This method has the advantage of being able to easily paint even if there is a curvature on the painted surface, but it takes a long time because the masking tape and the vinyl are cut to an appropriate size and attached to the frame.

Another method is to paint multiple layers of various colors and then laser-etch the uppermost layer to reveal the lower layer. Japanese Patent Registration No. 10-1341887 exemplifies that a painted layer of a cosmetic container composed of a curved surface is laser-etched as shown in FIG. 1B. This method is simpler than the method using masking tape and vinyl, but the layer to be painted at the top has a limitation in that it is required to use a material which is melted by a laser, such as a metal.

Another method is to use a masking jig. Conventionally, the jig covers parts other than the surface to be painted, and is formed in various shapes and sizes according to the surface to be painted as in the example of Fig. 1C. The use of masking jig has the advantages of shortening the working time, painting several times with the same quality, improving the accuracy of painting and automating the process, compared to the methods mentioned above.

In the present specification, a method of painting using a masking jig as an example of painting a two-tone color on the left white background surface as shown in FIG. 2A will be described. As shown in FIG. 2A, a two-tone paint can be divided into (1) using one masking jig and (2) using two masking jigs. FIGS. 2B and 2C are enlarged sectional views of the completed coloring surface AA 'and enlarged sectional views of the completed coloring surface using one masking jig, respectively. FIGS. 2D and 2E show the order of the coloring method using two masking jigs, FIG. Hereinafter, for convenience of understanding, the thickness of a layer to be painted is exaggerated to be thick, and a painted surface in green is referred to as a first painted surface, and a painted surface in blue is referred to as a second painted surface.

(1) In the case of using one masking jig, as shown in FIG. 2B, 1) it is painted slightly wider than the first painted surface and then dried, 2) the first colored surface is covered with a masking jig, and 3) Coloring surface is painted, and 4) masking jig is separated. However, according to the method (1), as shown in FIG. 2C, the first painted layer and the second painted layer are partially overlapped, so that the thickness of the entire painted layer is not uniform. Therefore, if the quality of the paint is poor, if the paint is damaged, the overlapped paint layer tends to be peeled off compared to other paint layers painted with a uniform thickness, resulting in poor durability.

(2) The method of using two masking jigs is applied when painting expensive parts or parts requiring precise coloring. At this time, the masking jig covering the second colored surface is called a first masking jig, and the masking jig covering the first colored surface is called a second masking jig. This method comprises the steps of 1) coating and drying the first colored surface after covering the first masking jig, 2) separating the first masking jig, 3) covering the second masking jig, 4) painting and painting the second colored surface, And 5) separating the second masking jig. As shown in FIG. 2E, the method (2) can be painted with a uniform thickness unlike (1). However, according to the method (2), unlike the above method (1), there are disadvantages that two masking jigs are required. It is a well-known fact that it takes a lot of time and money to manufacture a masking jig in the case of a surface complicated part. In addition, according to this method, if the surface to which the two masking jigs are abutted is not made to have an accurate dimension, a gap may be formed, and the gap may not be painted. To prevent this, the masking jig must be manufactured accurately and precisely, which makes it difficult to manufacture, and it takes time and expense. If the work of fixing each masking jig is not precisely performed, a gap that is not painted may occur between the two coloring surfaces, or the two coloring surfaces may overlap. In addition, since each masking jig must be fixed to the product and then loosened, it takes a long time to work.

Patent No. 10-1341887

According to the present invention, the masking jig and the masking liquid are painted in a uniform thickness while minimizing the number of masking jigs necessary for painting the first and second painted surfaces with the first and second colors different from each other, So that it is possible to improve the two-tone coloring method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the drawings are only illustrative of the content and scope of the technical idea of the present invention, and the technical scope of the present invention is not limited or changed. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples. Also, when reference numerals are used in the components of the claims, it is to be understood that they are merely illustrative and are not intended to limit the components.

In the flowchart of FIG. 3, which is one example of the present invention, the first colored area 11 and the remaining area except for the first colored area 11 are assumed to be the second colored area 12, There is no limitation on the shape and size of the painted surface. The first colored surface 11 and the second colored surface 12 are painted in a first color and a second color, which are different from each other, and are assumed to be green and blue, respectively. It is assumed that the masking jig 21 is seated on one of the two colored surfaces and, in one example, is seated on the first colored surface 11. [ In order to facilitate understanding of the colored layer, the thickness of the colored portion is exaggerated in the cross-sectional view, and the masking jig 21 is shown in a simple cover form for convenience of explanation.

The present invention is a two-tone painting method of painting a first colored area 11 and a second colored area 12 of a part in different colors using one masking jig 21 and masking liquid 30, (A) placing the masking jig (21) on the first colored surface (11) as shown; (B) painting and drying the exposed second colored surface (12) in a second color; (C) applying the masking solution (30) onto the second colored surface painted-dried; (D) The masking jig 21 is separated before the applied masking liquid 30 is dried or dried so that the masking jig 21 is easily separated, and the exposed first colored surface is subjected to a first painting ≪ / RTI > (E) separating the masking film (30).

In the step (A), the masking jig 21 is seated on the first colored surface 11. The edge of the masking jig 21 is formed in the same shape as the edge of the first colored surface 11. The masking jig 21 is seated with its edge exactly aligned so as to completely cover the first colored surface 11 .

In the step (B), the exposed second colored surface 12 is painted and dried. In this case, since the second colored surface 12, which is in contact with the peripheral portion of the outer peripheral surface of the masking jig 21, has a height difference from the masking jig 21, (See FIG. 3).

In the step (C), the masking liquid 30 is coated on the second painted surface 12 painted and dried. When the masking liquid 30 is applied, various methods such as spraying the masking liquid 30, painting with a roller and a brush can be utilized. The masking liquid 30 spreads evenly over the whole surface to be coated so that a part of the first colored surface 11 is not exposed. The masking jig 21 has a height difference between the masking jig 21 and the masking liquid 30 so that the masking jig 21 is coated with the masking liquid 30 to the whole or a part of the upper surface of the masking jig 21 Can be performed.

In the step (D), the masking jig 21 is separated before the applied masking liquid 30 is dried or dried so that the masking film 30 is easily separated, and the exposed first colored surface 30 11) is painted with a first paint and dried. The timing for separating the masking jig 21 may be such that when the masking liquid is slightly dried immediately after the masking liquid is applied and when the masking liquid is completely dried to form a thin film masking film, Depending on the subject or object. If the masking jig 21 is detached after the masking film 30 is formed, the upper surface of the masking film 30 may be exposed to the outside so that the outer peripheral portion of the first colored surface 11, which abuts the masking film 30, The entire or a part of the image can be painted.

In the step (E), the masking film 30 is separated to complete the two-tone painting. At this time, if the thickness of the masking film 30 is too small, it is difficult to separate the masking film 30. Therefore, it is preferable that the masking film 30 has a sufficient thickness when applying the masking solution 30.

Although the painting method based on two-tone is basically described in the present invention, it can be applied to multi-tone painting by applying the two-tone painting method. Although FIGS. 4A and 4B illustrate the partition surfaces to be painted with three colors and five colors, those skilled in the art will appreciate that the above-described method can be applied to other colors more easily.

The multi-tone painting method of the present invention is characterized in that (1) the masking jig (21) is seated on all of the partition surfaces (A) when the colored surface is partitioned into n surfaces and the adjacent partition surfaces are painted in different colors; 2) ensuring that all adjacent portions are surrounded by the masking jig 21; (B) repeating the process of painting and drying one of the partition surfaces corresponding to 2) of the step (A) until all the partition surfaces are painted; (C) applying a masking solution (30) onto the painted-dried partition surface in the immediately preceding stage, (2) applying a masking solution (30) to the partitioning surface corresponding to 1) A small step of selecting and separating one of the masking jigs 21 that are seated on the partition surface after the masking film 30 which is easy to be separated or dried before or after being dried is formed, (3) the separation of the masking jig 21 Repeating the painting process consisting of a small step of painting and drying the exposed section surface until all the section surfaces are painted; (D) removing all of the masking film 30 formed on the colored partition surface. FIG. 5 is a flow chart of an example of the multi-tone painting method, wherein the partition surface is based on the partition surface of FIG. 4B.

1) the masking jig 21 is seated, or 2) all the adjoining portions are surrounded by the masking jig 21 in the step (A). At this time, it is preferable to appropriately select the partition surface on which the masking jig 21 is seated so that the masking jig 21 can be used at a minimum. For example, as shown in FIG. 4A, there are three consecutively arranged first, second, and third partition surfaces, and when the second partition surface completely separates the remaining first and third partition surfaces, It is preferable that the masking jig 21 is seated. As another example, if there are five partition surfaces as shown in FIG. 4B, the masking jig 21 can be seated on the partition surfaces 3, 4, 5, or 1, 2, and 4 partition surfaces.

In step (B), one of the divisional surfaces is selected and painted and dried for all the divisional surfaces corresponding to 2) of the step (A) (in the example of FIG. At this time, it is possible to apply the coating to all or a part of the upper surface of the masking jig 21 so that each partition surface can be sufficiently painted on the outer peripheral portion abutting the masking jig 21. In the example of FIG. 5, the first and second partition surfaces are painted in the same color, and painting and drying are performed only once. However, in case of coloring with different colors, And repeating the steps of painting and drying.

In the step (C), three small steps are repeatedly painted on the partition surface corresponding to 1) of the step (A). ① In the small step, apply the masking solution (30) on the paint-dried partition surface in the immediately preceding step. The matters related to the masking liquid can be applied in the same manner as in step (C) of the two-tone painting method. In step (2), one of the masking jigs (21) seated on the partition surface is selected and separated before or after the applied masking liquid (30) is dried or dried so that the masking film (30) is easily separated. At this time, the timing for separating the masking jig 21 can be applied in the same manner as the step (D) of the two-tone painting method. (3) In the first stage, the partition surface exposed by the separation of the masking jig 21 is painted and dried. At this time, coloring may be performed to all or a part of the upper surface of the masking jig 21 so that the peripheral portion where each partition surface abuts the masking jig 21 or the masking film 30 can be sufficiently colored. In the case of the example shown in FIG. 5, the small steps of (1), (2) and (3) above were repeated three times on the partition surfaces 3, 4 and 5 where the masking jig 21 was seated.

In the step (D), the masking film 30 formed on the painted partition surface is completely removed to complete the painting.

On the other hand, in the step (B), 2) all of the partition surfaces surrounded by the masking jig 21 are all exposed. In this case, when the distance between the partition surfaces corresponding to 2) is close and all the partition surfaces are painted with different colors, there is a problem that when the selected partition surface is painted, the paint on the other partition surfaces becomes uneven Lt; / RTI > In order to prevent this, it is possible to further include a small step of forming a masking film 30 by applying a masking solution 30 on the painted-dried partition surface in the middle of the painting process for each partition surface and drying the applied coating solution.

If the color that is painted on the first selected partition face is darker than the color of the selected partition face later, when the color of the other partition face is painted during the first coloring, the color of the previously painted color is blurred Can be seen. In order to prevent this, it is possible to apply a method in which a masking liquid 30 is applied onto the entirety of the remaining partition surfaces before painting the first selected partition surface, and then the resultant is dried to form the masking film 30 have. In this case, it is possible to further include a small step of removing the masking film 30 covered on the partition surface before painting the next selected partition face.
