DETAILED DESCRIPTION OF THE INVENTION
The invention of this application has the features as described above, and an embodiment thereof will be described below.
FIG. 1 of the accompanying drawings is a cross-sectional configuration diagram illustrating a multicolored coated product of the present invention and a coating method therefor.
[0009]
For example, as illustrated in FIG. 1, in the multicolor coated product of the present invention, the base material (P) having the joint groove portion (D) has different colors (A) and (B) on the right and left of the joint groove portion (D). In addition, a color boundary (L) is provided in the joint groove (D). More specifically, in the case of FIG. 1, the joint groove portion (D) is V-shaped, and each of the groove inner wall surfaces (WA) (WB) is a base material on which each of them is continuous. (P) The surface color (A) is the same as (B). That is, in FIG. 1, the color (A) of the left groove inner wall surface (WA) is the same as the color (A) of the left substrate surface, while the color (B) of the right groove inner wall surface (WB) ) Is the same as the color (B) of the right substrate surface.
[0010]
Here, the “groove portion” will be further described. More preferably, from the viewpoint of appearance design and paintability, a V-shaped one as shown in FIG. 1 is considered, but it is not necessarily limited. Absent. It may be a groove having a bottom surface, a partially penetrating groove, or a curved groove. The base material surface that is “continuous” on the inner wall surface of the groove means a state “to reach the base material surface through another inner wall surface or an opposite inner wall surface” as can be seen from the example of FIG. This means that one groove inner wall surface and the base material surface are in immediate contact with each other.
[0011]
In the case of the multicolored coated product of the present invention as described above, the groove (D) is not painted with a third color different from the colors (A) and (B) as in the prior art. A) The visual effect of the combination of (B) is clear, and the presence of the joint groove (D) gives a unique sense of depth and depth. When the third color is applied to the groove (D) with respect to the colors (A) and (B), a sharp contrast between the colors (A) and (B) cannot be obtained. A) The combination sense of (B) may be impaired. Such a problem does not occur in the present invention.
[0012]
In the method for coating a multicolored coated product of the present invention, as illustrated in FIG. 1, the spray end (S) is placed at the boundary (L) of the color in the joint groove (D) as spray coating with a coating gun (G). It is characterized by painting to match.
In this method, as illustrated in FIG. 1, spray coating is applied from the lateral direction of the joint groove portion (D) to the base material surface having the same color (A) and the inner wall surface (WA) of the joint groove portion continuous thereto. To be considered.
[0013]
More specifically, FIG. 2 illustrates a case where a three-color coating of three colors (A), (B), and (C) is applied to the base material (P) as a planar arrangement of the coating gun.
Five paint guns are used, and each paint gun has a paint of a necessary color via a regulator by pump A, pump B and pump C corresponding to colors (A), (B) and (C), respectively. Will be sent. Painting is done in three steps. step1, step2, and step3. The painting of color (A) is step 1 and step 3 with two painting guns (1) and (3), the painting of color (B) is step 2 with one painting gun (2) and the painting of color (C) is As in the case of the color (A), the process is performed at step 1 and step 3 by the two coating guns (1) and (3).
[0014]
In order to clear the boundary between the colors, it is preferable to adjust the spray painting with a painting gun to be performed at a relatively low pressure. This is because, if the pressure is too high, the boundary between the colors tends to become blurred due to the spread of the sprayed paint. Although it depends on the distance between the coating gun and the substrate, as a general guideline, it is considered that the coating pressure is adjusted to a low pressure of 50 kg / cm ² or less.
[0015]
In the painting method of the present invention, by using a paint gun that can switch between multiple colors, it is possible to change the paint color partially by switching instantaneously.
For example, as illustrated in FIG. 3, for the first base material, the color (A) is applied by the paint guns (G1) and (G2), and the color (B) is applied by the paint gun (G3). Apply the paint, and instantly switch between multiple colors. On the second substrate, paint the color (C) with the paint gun (G1) (G2), and paint the color (A) with the paint gun (G3). For the guns (G4) and (G5), paint the color (B). In this way, it is possible to produce a coated product combining various colors on a continuous production line.
[0016]
As such a switchable paint gun, as illustrated in FIG. 4, a paint gun that can be switched by an electromagnetic valve is exemplified.
Of course, the invention of this application is not limited by the above examples. Various details are possible.
[0017]
【The invention's effect】
As explained in detail above, the invention of this application provides a multicolored coated product with grooves, which has a clear contrast between different colors and has a unique depth due to the presence of the grooves, and has an excellent appearance design of multicolored coating.
