2. Description of the Related Art Conventionally, a protective film has been attached to a painted surface in order to temporarily protect the painted surface until a painted object such as an automobile reaches the user's hand. However, when the washer nozzle is projected from the painted surface like a bonnet, the protective film cannot be simply attached to the entire bonnet because the washer nozzle needs to be used during transportation of the vehicle.

Therefore, JP-A-5-237935 discloses a method using two kinds of adhesive films.
In this method, a perforated adhesive film is attached to the coated surface around the washer nozzle while avoiding the washer nozzle protruding from the coated surface, and then the original adhesive film is attached to the entire bonnet from above. Then, the washer nozzle portion rises like a tent, so that portion is cut by a cutter so that the perforated adhesive film and the original adhesive film are overlapped.

SUMMARY OF THE INVENTION In the conventional method, rainwater is applied to the painted surface from the opening of the adhesive film formed by removing the original adhesive film covering the washer nozzle due to wrinkles or the like formed on the adhesive film. However, there is a problem that the quality of the coating film may deteriorate.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to form an opening in a protective adhesive film and attach it to a coated surface. Even if there is, it is an object of the present invention to provide a method for attaching a protective pressure-sensitive adhesive film that can reliably prevent rainwater and the like from entering the painted surface through the opening.

[0006]

In order to solve the above problems, the present invention is to attach a perforated protective adhesive film to a coated surface so as to surround a protrusion protruding from the coated surface, and then to adhere the perforated protective adhesive film. A protective pressure-sensitive adhesive film is attached to the entire painted surface to be protected from above the film, and then the protective pressure-sensitive adhesive film is removed so that the protrusions are exposed to form an opening, and rainwater or the like is further discharged from the opening of the protective pressure-sensitive adhesive film. It is provided with a means for preventing the invasion of the paint surface.

Means for preventing rainwater and the like from entering the coated surface through the opening of the protective pressure-sensitive adhesive film is to attach a waterproof tape along the edge of the opening of the protective pressure-sensitive adhesive film.

The means for preventing rainwater or the like from entering the painted surface through the opening of the protective pressure-sensitive adhesive film includes a blotting paper interposed between the perforated protective pressure-sensitive adhesive film and the protective pressure-sensitive adhesive film. May be

[Function] By attaching the waterproof tape to the opening of the protective pressure-sensitive adhesive film, rainwater or the like can be prevented from entering the painted surface through wrinkles or the like formed at the bonding portion between the perforated protective pressure-sensitive adhesive film and the protective pressure-sensitive adhesive film. It can be prevented. In addition, by interposing a blotter paper between the perforated protective adhesive film and the protective adhesive film, rainwater and the like that enter through the wrinkles and the like that occur at the bonded portion are absorbed and rainwater and the like reach the coated surface. Can be prevented.

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is an explanatory view showing a work order of the method of attaching the protective adhesive film according to claim 2, and FIG. 2 is a state of attaching the protective adhesive film around the washer nozzle by the method of attaching the protective adhesive film according to claim 2. FIG. 3 is an explanatory view showing a work order of the method for attaching the protective adhesive film according to claim 3, and FIG. 4 is a diagram showing the protective adhesive film around the washer nozzle according to the method for attaching the protective adhesive film according to claim 3. It is a top view which shows a pasting state.

In the method of attaching the protective pressure-sensitive adhesive film according to the second aspect of the present invention, as shown in FIG. 1A, the washer nozzle 2 does not hang around the washer nozzle 2 protruding from the coated surface of the bonnet 1 first. Stick the perforated patch 3 on the painted surface as shown. As the perforated patch 3, polyvinyl chloride, polyethylene, polypropylene,
Any material such as polyester, paper, cloth or metal foil can be used.

Next, a protective adhesive film 4 is attached to the upper surface of the bonnet 1, that is, the entire coated surface. This protective adhesive film 4 is made of the same material as the perforated patch 3. Then, as shown in FIG. 1B, the perforated patch 3
The protective adhesive film 4 is cut into a square shape by a cutter or the like so that the washer nozzle 2 is exposed so as to be larger than the opening and smaller than the outer diameter of the perforated patch 3.

Thereafter, as shown in FIG. 1C, a waterproof tape 5 is attached so as to cover the opening edge portion of the protective adhesive film 4 and the step portion formed by the perforated patch 3. By applying the waterproof tape 5 as described above, as shown in FIG. 2, the protective adhesive film 4 is exposed from the opening side of the protective adhesive film 4 to the coated surface of the bonnet 1 due to the wrinkles formed in the bonding portion of the perforated patch 3 and the protective adhesive film 4. The communication path that communicates is reliably cut off.
Therefore, it is possible to reliably prevent rainwater or the like from entering the coated surface of the bonnet 1.

Further, in the method of sticking the protective pressure-sensitive adhesive film according to the third aspect, as shown in FIG. 3A, first, the washer nozzle 2 protruding from the coated surface of the bonnet 1 is used.
Stick the perforated patch 3 on the painted surface so that the washer nozzle 2 does not get caught around.

Next, as shown in FIG. 3B, an annular blotting paper 6 is attached around the washer nozzle 2 onto the perforated patch 3.

After that, a protective adhesive film 4 is attached to the entire coated surface of the bonnet 1. Then, as shown in FIG. 3C, the protective pressure-sensitive adhesive film 4 is formed into a rectangular shape by a cutter or the like so that the washer nozzle 2 is exposed to be larger than the opening of the perforated patch 3 and smaller than the inner diameter of the blotter paper 6. Disconnect.

By interposing such a blotter paper 6 at the bonding portion between the perforated patch 3 and the protective adhesive film 4, as shown in FIG. 4, the perforated patch is provided from the opening side of the protective adhesive film 4. Rainwater and the like that enter through the wrinkles generated at the bonding portion of the protective adhesive film 3 and the protective adhesive film 4 are absorbed by the absorbent paper 6. Therefore, it is possible to reliably prevent rainwater or the like from entering the coated surface of the bonnet 1.

In this embodiment, the upper surface of the hood 1 of the automobile is shown as the painted surface and the washer nozzle 2 is shown as the projection, but the present invention is not limited to this.

[0019]

As described above, according to the present invention, a waterproof tape is attached along the opening edge portion of the protective adhesive film, or a blotter paper is provided between the perforated protective adhesive film and the protective adhesive film. By providing an intervening prevention means, it is possible to reliably prevent rainwater and the like from entering the painted surface, and maintain the quality of the painted surface.

When the protective pressure-sensitive adhesive film is attached to the perforated protective pressure-sensitive adhesive film, even if some wrinkles may occur on the protective pressure-sensitive adhesive film, rainwater or the like may be applied to the coated surface by the action of the waterproof tape or absorbent paper. Since it is possible to reliably prevent the intrusion, it becomes possible to easily and quickly attach the protective pressure-sensitive adhesive film, and the workability can be improved.
