Abstract

PURPOSE:To obtain a two-tone color painted product without stepped zones due to the thickness of a masking tape by applying a second color paint in such a condition that the end of a side on which a second color coat of the masking tape is formed is afloat. CONSTITUTION:A masking tape 3 is pasted on an object to be coated with a first color coat 2 formed in advance in such a manner that the tape covers a portion which becomes a parting line. Then the end of a second color coat is stripped off up to the position of the parting line. This end is bent inward in advance so that it may not adhere to the object to be coated 1 to form the floating part 4 of the tape. If the second color paint is sprayed using an ordinary spray gun 7 under this condition, the paint is introduced under the floating part 4 of the tape by entrainment of spray mists. Consequently, the coat under the floating part 4 of the formed second color coat 6 is thin and becomes thicker gradually from the parting line. Therefore, no stepped zone generates between both color coats 2, 6.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a two-tone painting method.

(Prior art) In the two-tone painting method, in order to form a highly accurate parting line, a first paint color layer 2 is formed by coating and baking a paint of a first paint color on the object 1 to be painted, As shown in FIG. 4, this is coated by spraying the paint of the second color while it is protected with masking tape 3.

(Problems to be Solved by the Invention) However, in the above coating method, as shown in FIG. 5, the second color layer 6 is thicker than the first color layer 2 by the masking tape 3, Therefore, a step will occur at the parting line. By the way, tape (design tape) is sometimes attached to two-tone painted products in order to draw stripes or letters.

At this time, if there is a level difference as described above, a level difference also occurs on the surface of the design tape 9, as shown in FIG. Such a step, like the boundary between the first paint color N2 and the second paint color layer 6,
If the color is different on both sides of the step, it is not so noticeable, but if the color on both sides of the step is the same, such as on the surface of a design tape, it is clearly visible to the naked eye as a highlight line, which is unfavorable in terms of appearance. .

The formation of highlight lines can be prevented by using a thicker decorative tape, but thicker decorative tapes are not only expensive but also undesirably easy to peel off. Therefore, an object of the present invention is to provide a two-tone painting method using a masking tape that does not cause a difference in level due to the thickness of the masking tape.

(Means for Solving the Problems) In order to achieve the above object, the two-tone coating method of the present invention protects the painted area with masking tape after forming a first color layer on the object to be coated. In the two-tone painting in which the second paint color layer is applied with the masking tape, the second paint color layer is applied with the end of the masking tape on the side where the second paint color layer is formed raised.

The masking tape is pasted on the first colored layer so as to cover the parting line between the first colored layer and the second colored layer, and the side of the tape where the second colored layer is formed. Peel off the edge of the paper to the parting line to make it stand out. It is preferable that the raised portion be folded back toward the adhesive surface and adhered so that it does not stick to the object to be coated.

Coating is carried out by spraying from a spray gun or the like in the same way as in the usual method.

(Function) According to the present invention, when the second paint color is sprayed with the end of the masking tape raised, the second paint color enters below the raised masking tape due to the paint spray mist being involved. . As a result, a second painted color layer is formed as a parting line where the masking tape adheres to the object to be coated.

The paint film on the part that was under the lifted masking tape is thin, but gradually increases in thickness from the parting line. As a result, a two-tone coated product with no step difference between the first color layer and the second color layer can be obtained.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a state in which a masking tape 3 is adhered to an object 1 to be coated on which a first color layer has been previously formed by the two-tone coating method of the present invention.

The masking tape 3 is pasted so as to cover the part that will become the parting line, and the end on the second painted layer side is peeled off to the position of the parting line. The end portion is bent inward in advance to form a tape floating portion 4 so as not to adhere to the object 1 to be coated. In this state, a two-tone second paint color is sprayed using an ordinary spray gun 7 or the like to form a second paint color N6 as shown in FIG. At this time, the paint of the second paint color enters under the tape floating part 4 and forms a thin film part 5 of the second paint color layer. The thin film portion 5 gradually increases in thickness from the point where the masking tape 3 is attached to the object to be coated. Therefore, the second painted color layer 6 is formed as a smooth continuous surface without creating a step between it and the first painted color layer 2.

A design tape 9 was attached to the thus formed two-tone painted object 8 as shown in FIG. Since there is no difference in level between the first color layer and the second color layer of the two-tone painted object 8, the design tape 9 has no difference in level, and no highlight lines or the like occur, giving it an excellent appearance. present.

(Effects of the Invention) The two-tone coating method of the present invention forms the second colored layer with the edges of the masking tape raised, so
There is no difference in level between the first color layer and the second color layer due to the thickness of the masking tape. Therefore, when a design tape is pasted on top of this and a pattern or character is drawn, highlight lines due to differences in level will not occur on the design tape. For this reason, as in the case of using a thicker design tape to prevent unevenness in the design tape in the conventional method,
Problems such as an increase in tape cost and easy peeling of the tape do not occur. Therefore, a coated product exhibiting an excellent appearance can be obtained by a simple method at low cost.
