DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection method for temporarily protecting a painted surface when a painted vehicle is transported or exported.

[0002]

2. Description of the Related Art Conventionally, as a technique for temporarily protecting a painted surface from rain, splashed pebbles, salt damage, etc., when transporting a finished vehicle that has been painted and assembled or exporting it overseas. For example, a technique as disclosed in JP-A-3-267171 is known. In this method, instead of applying wax or the like to the painted surface of the completed car and protecting it,
A plastic film having a peelable pressure-sensitive adhesive is attached to cover the vehicle body. For example, after thermoplastic resin is softened, it is adhered to the upper surface of the vehicle body using a vacuum and protected. Like that.

[0003]

However, in such a technique, since one protective film is used to cover the entire surface of the vehicle, the front window, the side window,
A protective film is stuck to a part that does not need to be protected, such as a rear window, which raises a problem of increased cost. In addition, even if such a protective film is transparent, when mounted on a truck such as a car carrier, a ship, or the like, the visibility may not be sufficiently obtained when attempting to mount the film by self-propelled driving. In the case of a film having a layer, the field of view is extremely limited, which may cause danger. Also, in order to secure such a field of view, it is not possible to use a colored film such as white or black, which is effective in protecting the coating film. An extra process such as cutting was required, which increased the cost. Furthermore, the film end portion is only adhered in a state of being wound on the back side of the front and rear end portions such as a bonnet or the like, and its adhesive force is also weak, and the above-mentioned vacuum-based adhesion is not strong. Therefore, there is a problem that the film is easily peeled off during transportation. When rain and wind hit the peeled portion, the film gradually turned up, exposing the area to be protected, and could not fulfill its original purpose.

[0004]

[Means for Solving the Problems] To solve such problems.
The present invention temporarily protects the painted surface of a painted vehicle
A method, spray the strippable paint with other spray coating process by a coating method along the outer edge of the coercive Mamorusu should range without dust, such as roller or brush
A step of applying to an application width not affected by dust,
Strippable paint over a smaller area to protect
And spray coating.
Performs prior to square the process, characterized by being so provided overlapped portion coating the application range of each other.

[0005]

[Action] Spray dust the strippable paint with other spray coating process by a coating method without dust roller or brush or the like along the outer peripheral edge of the range to be protected
By applying a coating width that is not affected by the above, and spray-applying the strippable paint in a range narrower than the range to be protected, the efficiency of the coating operation can be improved, and the subsequent operation steps can be simplified. In other words, if you try to apply the strippable paint over the entire area of the coating surface to be protected, the spray dust adheres to the front grille or small gaps, making it difficult to remove, and masking measures are required.
While problems arise in workability and cost, work efficiency is poor if an attempt is made to apply the entire area to be protected with a roller or brush.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for temporarily protecting a paint film of a vehicle body according to the present invention will be described.

[0007] When a painted finished vehicle is transported by a car carrier or exported overseas by ship, the painted surface is protected from deterioration, damage and the like during transportation to prevent a reduction in commercial value. There is a need.

[0008] As described above, if the protective film is applied over the entire surface of the vehicle as described above, it is uneconomical to attach the protective film to an unnecessary portion such as a window. Hood,
It is also conceivable to cut the film according to the shape of the area to be protected, such as a door or a fender, and to stick it only at a truly necessary place.

However, the shapes of such hoods and doors differ depending on the target model, and the cutting operation becomes very complicated, and it is difficult to automate the operation. In addition, the adhesiveness of the film edge cut according to the shape becomes a problem,
It is necessary to devise it so that it does not easily come off.

[0010] Further, as described above, when the spray coating is to be applied to the entire surface of the coating, the spray dust scatters to a peripheral unnecessary portion, particularly when the peripheral portion is applied,
For example, if it gets into and adheres to a gap in a front grill or the like, it is almost impossible to remove it later. Therefore, measures such as masking are required for such portions in advance, which leads to a significant increase in cost.

On the other hand, if an attempt is made to apply the entire surface of the coating surface with a roller, brush, or the like, the work efficiency is poor and time is required.

Therefore, in the present invention, when the coating surfaces of the hood 2, roof 3 and trunk 4 of the vehicle 1 as shown in FIG. A range of a certain width as indicated by hatching along the outer peripheral edge of the trunk portion 4 is coated with a stripper paint by a coating method that does not involve dust such as a roller or a brush to form a coating layer a, and then, or Before that, a coating layer b is formed by spray-coating the inside surrounded by hatching (portions indicated by dots in the figure), and between the coating layer a by a roller or the like and the coating layer b by spray coating as shown in FIG. To form an overlaid portion c.

The coating width (hatching width) by the roller or the like is set based on a distance such that the influence of the spray dust does not reach the surrounding windows or the like during spray coating for coating the inside. And
Also, the order of application by a roller or the like and spray application may be different.

Hereinafter, specific embodiments will be described.

For example, a roller having a width of 100 mm with wool or mohair operated by a coating robot or a roller of the same size made of urethane sponge or a brush having a width of 50 mm can be stripped along the outer peripheral edge of the area to be protected. Paint (Lapp Guard L, manufactured by Kansai Paint Co.) is applied in a width of 100 to 150 mm.

In this case, it is preferable to apply the coating not only on the coating surface but also on, for example, a washer nozzle and around the antenna.

Thereafter, the same paint is spray-coated on the inside using an airless type or air atomization type coating gun, so that the previously applied portion and the overcoated portion are formed. At this time, if an airless type coating gun is used, the spray dust is small, and the film thickness can be increased by one spraying, so that the working efficiency is improved and it is convenient.

According to this method, a protective film can be easily formed only at a place where protection is required, and the protective layer applied and formed in such a manner is more likely to be peeled off during transportation than when a film is attached. There is no.

[0019] Further, the provision of the over-painted portion allows one.
It becomes a single film, and the procedure for peeling is simple.

[0020]

As described above, the method for temporarily protecting a paint film of a vehicle body according to the present invention does not cause problems such as a restriction on the field of view during self-propelled traveling when the entire vehicle body is covered with a protective film, or the peeling of the film. A reliable protective layer can be formed at a necessary place by the strippable paint. or,
The cost can be reduced by not forming a protective layer in unnecessary places. In addition, by combining the application using a roller or the like and the spray application, unnecessary application in a subsequent process can be efficiently performed.
