Abstract

PURPOSE:To increase masking efficiency and to prevent masking failure by applying masking to a hinge, which partly projects from the surface of an automobile body outer sheet to be subjected to multicolor coating, by combining a patterned tape with a masking agent. CONSTITUTION:An ordinary patterned tape previously cut into the prescribed shape is stuck on the sheet surface having perfectly flat surface and the sheet surface part having large curvature in a hinge (h). An ordinary masking agent is applied to a sliding surface 4, a surface 5 in a sheet-thickness direction, and a peripheral part 6 of the stuck tape by means of a brush, an oiler, a sponge, etc. It is preferable to apply the masking agent so that it overlaps the edge of the patterned tape by about 1-2mm.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for masking a hinge.

More specifically, the present invention relates to a method for masking hinges that appear on the outer surface of an automobile body that is painted in multiple colors, and that allows masking to be performed reliably in a short period of time.

[Prior Art and Problems to be Solved by the Invention] The back door of off-road type automobiles usually adopts a side hinge system, and in order to increase the door opening angle, the mail part and the filler part that make up the hinge are The structure is such that the mail part and pin part are exposed on the outer surface of the automobile body (see Figure 2).

When applying multicolor painting such as two-tone painting to an automobile body having such a structure, it is common to provide a parting portion between a plurality of side hinges from a design point of view.

For example, when applying two-tone paint to a car as shown in Figure 2, the upper hinge (11) and the lower hinge (1
2), a parting portion is provided between the two. Conventionally, the first color is applied to the lower half of the body and then baked, the area below the cutout is masked with paper, and then the second color is applied to the upper half of the body. was.

However, when painting the second color, the back door may be opened and closed in order to paint the inside of the door or the door opening, but with the paper masking method described above, when opening and closing the back door, the hinges must be opened and closed. The paper for the second part was torn, and the paint for the second part was smeared onto the lower hinge, severely damaging the appearance of the hinge area.

For this reason, it is common practice to attach mold tape or apply a masking agent such as strip paint only to the hinge portion. The method of attaching the mold tape is to simply attach tape cut to match the shape of the hinge (separate tape for the male part and female part must be prepared) to the designated area, so it can be used over a wide area. It can mask surfaces quickly and has excellent workability. On the other hand, in the method of applying a masking agent, a liquid masking agent is applied using a brush, an oiler, a sponge, etc., so even curved surfaces and details can be freely masked.

However, in the method of pasting a mold tape, it is very difficult to reliably apply the tape to curved surfaces and details, and there is a problem that some areas are inevitably masked. In addition, with the method of applying masking agent, it takes time to coat a wide surface, and the film thickness distribution becomes uneven, so when the masking is removed, it does not peel off cleanly and breaks in the middle, resulting in thin film parts. The problem is that it remains as is.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, it is an object of the present invention to provide a hinge masking method that eliminates the drawbacks of the prior art and allows reliable masking in a short period of time.

[Means for Solving the Problems] A method for masking a hinge of the present invention is a method for masking a hinge that appears on the outer surface of an automobile body that is painted in multiple colors, and includes A masking agent is applied to the sliding surface, the thickness direction surface, and the peripheral edge of the mail part and the pin part, and mold tape is applied to the main surface of the plate other than the sliding surface, thickness direction surface, and peripheral edge. It is characterized by being worn.

In other words, the masking method of the present invention utilizes the advantages of mold tape and masking agent, and combines them to compensate for each other's shortcomings.The masking method of the present invention utilizes the advantages of mold tape and masking agent, and combines them to compensate for the drawbacks of each other. The curved surface portion is masked with a masking agent.

[Example] The hinge masking method of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an enlarged explanatory view of a hinge appearing on the outer surface of an automobile body as shown in FIG. 2. FIG. In Figure 1,
(h) is a hinge, and the hinge (h) has a mail part (
1), a female part (2), and a bottle part (3).

Of the hinge (h), an ordinary mold tape cut in advance into a predetermined shape is pasted to the wide main surface of the plate (the area shown by diagonal lines in FIG. 1). In this specification, the main surface of the plate includes not only a completely flat surface but also a curved surface with a large curvature to which a mold tape can be attached.

The sliding surface (4) between the male part (1) and the female part (2) (the part that is exposed when the door is opened and hidden when the door is closed), in the plate thickness direction. A water-based coating containing vinyl acetate as the main component is applied to the surface (the side surface of the board that constitutes the male and female parts, for example, the part shown in (5) in Figure 1) and the peripheral part (6). Ordinary masking agents such as film-protecting wax are brushed off,
Applied with an oiler, sponge, etc. In addition, in order to perform masking reliably, the masking agent is preferably applied so as to overlap the edge of the mold tape to some extent (approximately 1 to 2IiI11).

In this way, mold tape is pasted on the main surface of the plate, which has a relatively large area, and masking agent is applied to other surfaces, such as sliding surfaces, so the work can be done efficiently and in a short time. In addition, it is possible to perform masking reliably without producing any masking defects.

[Effects of the Invention] As explained above, according to the masking method of the present invention, a method of attaching tape and a method of applying a masking agent are used depending on the part of the hinge, and the advantages of each are utilized to overcome the disadvantages. This makes it possible to mask and then remove the mask in a short time, and it is also possible to reliably mask the hinge that moves when the door is opened or closed during painting work.
