Abstract

PURPOSE:To contrive the improvement of operational efficiency by covering the not coating part of the object to be coated with the masking material formed of a plastic material. CONSTITUTION:A masking material 1 made of aluminum and the like, formed into a sheet-like shape and having one edge bonded with a adhesive tape 2 throughout its length is cut into a predetermined length. This masking material is so positioned as to enclose an not coating part 3a on a bumper 3 and the tape 2 is attached to a boundary between the uncoated part and a coating part 3b. The masking material is bent in the direction of the allow A and encloses the entire surface of the not coating part 3a. The masking part forced out from the rear end of the bumper 3 is bent inwardly, the overlapped parts are made round into a small sealed or blocked condition or the part corresponding to the curved contour of the bumper 3 is pressed to be deformed, thereby correcting the masking material to a proper shape. At this time, since the masking material 1 itself is plastic, the shape of the masking material can be retained, even if an external force is released.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a masking method applied during painting.

[Conventional technology]

BACKGROUND ART Conventionally, when painting an object to be painted, etc., masking has been applied to the required portions of the object.

For masking, a masking material formed into a sheet of resin such as polypropylene is usually used, and the non-painted parts of the object to be painted are covered with this masking material. At this time, an adhesive tape or the like is interposed between the masking material and the object to be painted at a portion of the masking material corresponding to the boundary line of the coating to eliminate a gap between the two.

When masking is applied in this way, even if the paint is applied to the entire object to be painted, the paint will not be applied to the parts covered by the masking material, making it extremely easy to work on the parts to be painted. can.

[Problem to be solved by the invention]

By the way, when masking is applied as described above,
It is desirable to make the masking material match the shape of the object to be painted, and to perform painting with the gap between the masking material and the object completely eliminated. In other words, by matching the masking material to the shape of the object to be painted, it is possible to prevent paint from entering unpainted areas through the gap between the two, and prevent mist-like paint from re-adhering to painted areas due to reflection from the masking material. can do.

However, when a resin masking material is used as in the conventional method described above, in order to make the masking material match the shape of the object to be coated, it is necessary to apply adhesive tape around the entire periphery of the masking material. , it is necessary to apply adhesive tape to areas other than those corresponding to the boundary line, which makes the work extremely complicated.

In view of the above-mentioned circumstances, an object of the present invention is to provide a masking method that can improve workability.

[Means to solve the problem]

In the masking method according to the present invention, a non-painted part of an object to be painted is covered with a masking material molded from a plastic material.

[Effect]

According to the above configuration, the masking material conforms to the shape of the object to be painted due to its own plasticity.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, the present invention will be described in detail based on drawings showing embodiments.

FIG. 4 conceptually shows the masking material 1 applied to the masking method according to the present invention. This masking material 1 is formed into a sheet shape from aluminum, and an adhesive tape 2 is adhered to the entire length of the negative side edge.

Hereinafter, with reference to FIGS. 1 to 3, a method for painting a portion of a four-wheel vehicle bumper (object to be painted) 3 using the masking material 1 will be described.

First, the masking material 1 is cut to a required length (sufficiently longer than the bumper 3), and as shown in FIG.
Adhesive tape 2 is pasted on the part located at the boundary with the painted part 3b in a.

Next, the masking material 1 is bent in the direction of the arrow in FIG. 1(b) to cover the entire surface of the non-painted portion 3a of the bumper 3, as shown by the two-dot chain line in the figure.

Furthermore, the portion of the masking material 1 protruding from the rear end of the bumper 3 is bent inward and placed along the back surface of the bumper 3, as shown in FIG.

From this state, shaping is performed such as rolling the overlapping parts of the masking material 1 into small shapes and sealing them, or pressing and deforming the parts corresponding to the curved shape of the bumper 3, and the masking of the bumper 3 is completed.

The above-mentioned shaping work of the masking material 1 can be easily carried out without applying a large force because the masking material 1 is formed from an aluminum sheet material, and furthermore, since the masking material 1 itself has plasticity. , it remains in that state even when the external force is removed.

After masking is completed as described above, if the bumper 3 is painted by spraying or the like, the paint will be applied only to the areas other than those covered by the masking material 1, so as shown in FIG. The bumper 3 can be easily painted differently.

Moreover, in painting the bumper 3, since the masking material 1 also has heat resistance, the paint can be forcibly dried using a heating device.

In the above embodiment, the masking material 1 is formed by forming aluminum into a sheet shape, but the present invention is not limited to this, and masking materials can be formed using other materials as long as they have plasticity. It does not matter if it is composed of materials.

Further, in the above embodiment, the bumper 3 for a four-wheeled vehicle is exemplified as the object to be painted, but it is of course applicable to other objects to be painted.

〔Effect of the invention〕

As explained above, according to the masking method of the present invention, since the masking material conforms to the shape of the object to be painted due to its own plasticity, it is necessary to use a holding means such as an adhesive tape around the entire periphery of the masking material. This makes the work easier.
