Abstract

PROBLEM TO BE SOLVED: To contrive the improvement of the workability for pasting a protective self-adhering film to an automotive painted surface for protection. SOLUTION: A protective self-adhering film 1 for protecting an automotive painted surface by pasting it onto the surface of the automotive painted film has the same shape as that of the surface of the painted film. A large number of the protective self-adhering films 1 are laminated to one another. By pasting the protective self-adhering film 1 separated form the laminate onto the surface of the painted film, the protection of the surface of the painted film is contrived and the trimming work after pasting is made unnecessary and the improvement of the workability is contrived.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated protective film which is applied to the surface of a coating film of an automobile to protect the coating film.

[0002]

2. Description of the Related Art In general, a protective adhesive film is applied to the surface of a coating film to prevent the surface of the coating film from being stained or damaged during transportation of the vehicle until it reaches a customer's hand. Has been commonly practiced in the past.

[0003]

By the way, when sticking the protective adhesive film to the surface of the coating film, conventionally, the protective adhesive film is pulled out from the film roll, and is stuck on the coating film surface in order from the end, and then the cutter knife is used. The protective adhesive film is formed in the same shape as the surface of the coating film by the trimming operation to be used to remove an extraneous portion in the periphery, which is very troublesome.

In protecting the front bonnet having the washer nozzle, if the entire front bonnet is covered with a protective adhesive film, the washer nozzle cannot be tested and the windshield cannot be cleaned. After sticking, the portion facing the washer nozzle was cut off using a cutter knife, and at this time, there was a risk of damaging the coating film surface with the cutter knife.

[0005] An object of the present invention is to improve workability in protecting automobile coating films by sticking a protective adhesive film.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a protective pressure-sensitive adhesive film for protecting a paint film by attaching the paint film to the surface of a paint film of an automobile is formed in the same shape as the paint film surface. And a structure in which many of the protective adhesive films are laminated.

Further, in the present invention, a configuration is employed in which a hole is formed in the protective adhesive film so as to face a portion not requiring protection on the coating film surface.

According to the above construction, since the protective pressure-sensitive adhesive film has the same shape as the surface of the coating film to be protected, the protective pressure-sensitive adhesive film is peeled off and attached to the coating surface by a simple operation. The entire surface can be protected, and workability can be improved because trimming work is unnecessary.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a laminated protective film for protecting the surface of a coating film on a front hood of an automobile. This laminated protective film comprises a large number of laminated protective adhesive films 1.

As shown in FIG. 2, the protective pressure-sensitive adhesive film 1 has a pressure-sensitive pressure-sensitive adhesive layer 3 on one surface of a film substrate 2.

Here, as the film substrate 2, polyvinyl chloride, polyethylene, polypropylene, polyester or the like can be employed.

On the other hand, examples of the pressure-sensitive adhesive layer 3 include vinyl resin, polyester resin, alkyd resin, silicone resin, natural rubber, and synthetic rubber.

The protective pressure-sensitive adhesive film 1 is formed in the same shape as a front hood of an automobile. The protective adhesive film 1 has a hole 4 at a position facing a washer nozzle provided on the front bonnet, into which the washer nozzle can be inserted.

After laminating a large number of the protective pressure-sensitive adhesive films 1, the protective adhesive film 1 may be punched into the same shape as the front bonnet, or may be trimmed into the same shape as the front bonnet before lamination.

[0016] The laminated protective film having the above structure is
One protective adhesive film 1 is peeled off, and as shown in FIG. 3, the protective adhesive film 1 is attached to the front hood of the automobile A to protect the coating film surface. In this case, as shown in FIG. 4, the protective adhesive film 1 is attached so that the washer nozzle b provided on the front bonnet a is inserted into the hole 4 formed in the protective adhesive film 1.

Here, since the protective adhesive film 1 is formed in advance in the same shape as the front bonnet a, the trimming work after the application of the protective adhesive film 1 can be omitted, and the protective adhesive film 1 can be removed.
Is provided with a hole 4 at a portion facing the washer nozzle, so that it is not necessary to perform a hole forming operation after attaching the film.

Therefore, the work of protecting the coating film surface by attaching the film can be performed efficiently in a short time, and it is not necessary to cut the protective adhesive film using a cutter knife, so that the coating film surface is damaged. The inconvenience described above can be completely eliminated.

In order to facilitate the peeling of the protective pressure-sensitive adhesive film 1, the pressure-sensitive adhesive layer 3 at the corner of the protective pressure-sensitive adhesive film 1 is removed or a piece of paper is adhered to the pressure-sensitive adhesive layer 3 at the corner. It is good to provide an impossible part.

In the embodiment, the protective adhesive film 1 of the laminated protective film is formed in the same shape as the front bonnet. However, the protective adhesive film 1 conforms to the surface shape of the coating requiring protection. Let it. For example,
When protecting the coating surface of the roof, it has the same shape as the roof. When protecting the coating surface of the trunk lid, it has the same shape as the trunk lid. Furthermore, when protecting the paint film surface of the door, it is formed in the same shape as the door,
A hole is made in the part facing the pull handle.

[0021]

As described above, according to the present invention, the protective pressure-sensitive adhesive film for protecting the coating film by pasting it on the surface of the coating film is formed in the same shape as the surface of the coating film. The subsequent trimming operation can be omitted, and workability can be improved.

Further, since holes are formed in advance in portions that do not require protection, it is not necessary to make holes after attaching the film, and since there is no need to use a cutter knife, there is no danger of damaging the coating film surface. .
