[0018]

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

FIG. 1 shows an example in which a coating film is protected on a trunk lid 10 as an opening / closing member of a vehicle body. After the vehicle body coating is dried, first, the trunk lid 10 in an open state is shown.
The re-peeling pressure-sensitive adhesive 2 is applied in a predetermined width along the outer periphery of the back surface of the.

The removable pressure-sensitive adhesive 2 is a trunk lid 1
On the back surface of 0, 20 to 5 from the outer peripheral end toward the inner peripheral
A predetermined width of 0 mm and 1 to 100 μm (preferably 1
It is applied to the entire circumference in a thickness of 0 to 30 μm).

Here, the removable pressure-sensitive adhesive 2 is composed of an adhesive such as a water-based rubber-based pressure-sensitive adhesive or a water-based acrylic-based pressure-sensitive adhesive, and as the water-based pressure-sensitive adhesive, polytron (Asahi Kasei Kogyo Co., Ltd. Or manufactured by Rikidyne (manufactured by Sankyo Chemical Industry Co., Ltd.).

Next, the surface of the trunk lid 10 is covered with the plastic film 3 cut into a predetermined size, and then the outer periphery of the plastic film 3 is covered with the trunk lid 1.
Bend to the back of 0. Then, the outer peripheral edge of the plastic film 3 is pressed against the layer of the removable pressure-sensitive adhesive 2 applied to the back surface of the trunk lid 10.

The plastic film 3 has a thickness of 1 to 100.
It is made of a bendable film-like resin having a thickness of 0 μm (preferably 30 to 50 μm), for example, a film of polyethylene or polyethylene or a polyethylene / polypropylene copolymer.

Here, when the thickness of the plastic film 3 is less than 1 μm, the rigidity of the plastic film 3 itself is insufficient. Therefore, when the plastic film 3 is fixed to the vehicle body, positioning is performed by the influence of external force such as wind. The work may be difficult, while if it exceeds 1000 μm, the rigidity of the plastic film 3 becomes excessive,
The bending work at the end of the trunk lid 10 becomes difficult and the work efficiency is reduced. Therefore, by setting the thickness of the plastic film 3 to 1 to 1000 μm, and more preferably 30 to 50 μm, the plastic film 3 can be efficiently positioned and fixed to the trunk lid 10.

The size of the plastic film 3 is set to be larger than the outer peripheral surface of the trunk lid 10 and has a predetermined width (for example, 70 mm) to the outer periphery of the trunk lid 10.
It is formed in advance so as to project.

The plastic film 3 covering the outer peripheral surface of the trunk lid 10 has its outer peripheral end bent to the rear end of the trunk lid 10, and the outer peripheral end of the plastic film 3 is applied to the rear peripheral surface of the trunk lid 10. The removable pressure-sensitive adhesive 2 is fixed by being pressed. In addition, since the removable pressure-sensitive adhesive 2 is applied to the back surface of the trunk lid 10, it is possible to prevent the coating film on the outer peripheral surface of the trunk lid 10 from being damaged by the operator's error during the applying operation. is there.

After that, the trunk lid 10 whose surface is covered with the plastic film 3 is closed to complete the protection of the coating film.

Here, the relationship between the coating width of the removable pressure-sensitive adhesive 2 and the peeling strength indicating the force required for peeling the plastic film 3 is as shown in FIG. 2 according to the experiment by the inventor of the present application. It was

Here, the peeling strength is "JIS K
The force required for peeling the plastic film 3 was measured based on the "automobile adhesive test method" defined in "6829-1994", and the result of this experiment is defined in "17.3.1" of the JIS standard. "180 degree peel test"
The measurement conditions are a temperature of 20 ° C., a humidity of 70% and a pulling speed of 300 ± 30 mm / min. For details of the experimental method, refer to the above JIS standard.

In FIG. 2, the peeling strength increases as the coating width of the removable pressure-sensitive adhesive 2 increases. By setting the coating width of the removable pressure-sensitive adhesive 2 to 20 to 50 mm, the peeling strength is 3 to 8 N (preferably 4 to 6 N).
The peeling strength can be set within the range of 3 to 8
If N, the plastic film 3 can be fixed against external force such as wind, while the plastic film 3 can be easily peeled off.

If the peeling strength is less than 3N, the adhesion of the plastic film 3 is low at the time of traveling at high speed when transporting the finished vehicle on a trailer or the like, so that it may be peeled off from the vehicle body according to the experiments by the inventor of the present application. On the other hand, when the peeling strength exceeds 8 N, not only the force required for peeling becomes excessive and the workability is deteriorated, but also when the plastic film 3 is deteriorated with time, the peeling strength is deteriorated. There is a case where the plastic film 3 is partially broken and a great amount of labor is required for this peeling work.

Therefore, by setting the coating width of the removable pressure-sensitive adhesive 2 to 20 to 50 mm, the peeling strength of the plastic film 3 becomes 3 to 8 N, and the plastic film 3 covering the outer peripheral surface of the trunk lid 10 is obtained. While it can be held against external force such as wind pressure, the plastic film 3 can be easily peeled off after the end of storage or transportation.

Further, the thickness of the removable pressure-sensitive adhesive 2 is set to 1
˜100 μm (preferably 10-30 μm)
The reason is as follows.

If the coating thickness is less than 1 μm, not only is it extremely difficult to form a layer of the removable pressure-sensitive adhesive 2 on the vehicle body, but also a predetermined adhesive force cannot be secured, so the plastic film 3 Peels off easily.

On the other hand, the removable pressure-sensitive adhesive 2 has a thickness of 10
If it exceeds 0 μm, the adhesive force increases, and not only a great deal of labor is required for the peeling work of the plastic film 3, but also the peeling-type pressure-sensitive adhesive 2 undergoes cohesive failure during this peeling, which causes the coating of the vehicle body. The removable pressure-sensitive adhesive 2 may remain on the film.

Therefore, the thickness of the removable pressure-sensitive adhesive 2 is set to 1 to 100 μm (preferably 10 to 30 μm) so that the plastic film 3 is firmly fixed, while the plastic film 3 remains on the vehicle body when peeled off. It is possible to reduce the removable pressure-sensitive adhesive 2.

In this way, since the outer peripheral surface of the trunk lid 10 is protected by the plastic film 3, the coating film is protected from environmental factors (stepping stones, dust, iron powder, gas, chemicals, etc.) in the storage and transportation processes. It can be stored or transported without degrading its value.

On the other hand, in order to remove the plastic film 3 after finishing transportation, open the trunk lid 10 and
This is performed by peeling the outer periphery of the plastic film 3 fixed to the outer periphery of the back surface of the trunk lid 10.

The plastic film 3 has a peripheral edge portion of 20.
Since it is only fixed with a width of ~ 50 mm, it can be peeled off more easily than the conventional example, and the trunk lid 10
The re-peelable pressure-sensitive adhesive 2 applied to the outer periphery of the back surface of the can be easily washed off with water or the like, reducing the labor required for the peeling work of the plastic film 3 as compared with the conventional example, and at the same time coating the vehicle body. The removable pressure-sensitive adhesive 2 remaining on the film can be reliably removed.

Although not shown, the same protection method as described above can also be applied to the hood as an opening / closing member of the vehicle body. The hood can be freely opened / closed to surely protect the coating film. The plastic film 3 can be easily peeled off.

FIG. 3 shows the second embodiment. In contrast to the first embodiment in which the trunk lid 10 which is the opening / closing member of the vehicle body 1 is covered with the plastic film 3, the present embodiment is different from the first embodiment. The roof 11 which is a fixed outer plate of the vehicle body 11 is coated with the plastic film 3.

First, the removable pressure-sensitive adhesive 2 similar to the above is applied in a predetermined width from the outer peripheral end of the roof 11 for protecting the coating film toward the side surface of the vehicle body 1.

In this case, since the removable pressure-sensitive adhesive 2 cannot be applied to the back surface of the roof 11, the roof 11
The re-peelable pressure-sensitive adhesive 2 is applied with a width of 20 to 50 mm to the upper and lower ends of the front and rear glass and the upper end of the door 12 along the outer periphery of the.

Next, as in the first embodiment, the roof 11 is made of the plastic film 3 cut into a predetermined size.
And the outer peripheral edge of the plastic film 3 is pressed against the layer of the removable pressure-sensitive adhesive 2 to fix it to the vehicle body 11 in the same manner as above, and the plastic film 3 is used to securely protect the coating film while carrying it. After the above process is completed, the plastic film 3 can be easily peeled off, and the removable pressure-sensitive adhesive 2 applied to the front and rear glass and the door 12 can be easily removed with water or the like.

FIG. 4 shows the third embodiment. In contrast to the second embodiment in which the re-peelable pressure-sensitive adhesive 2 is applied to the upper end portion of the door 12, in the present embodiment, the sash 14 of the door 12 is used. The re-peelable pressure-sensitive adhesive 2 is applied to the outer peripheral side surface of the roof side rail 13 as a door opening portion to which the weather strip 15 disposed on and off is attached in a width of 20 to 50 mm in the same manner as described above. Is the same as in the second embodiment.

The plastic film 3 is fixed in the longitudinal direction of the vehicle body in the same manner as in the second embodiment, and the lateral side of the plastic film 3 is fixed by the removable pressure sensitive adhesive 2 applied to the roof side rail 13. At the same time, since it is sandwiched between the weather strip 15 provided on the sash 14 of the closed door 12 and the roof side rail 13, the plastic film can be reliably resisted against external force such as wind applied during transportation of the vehicle. It is possible to hold 3.

In the third embodiment, the releasable pressure-sensitive adhesive 2 is applied to the roof side rails 13,
The door 12 shown in FIG. 4 without applying the removable pressure-sensitive adhesive 2.
The plastic film 3 may be sandwiched between the weather strip 15 and the roof side rail 13 in this case. In this case, since the application area of the removable pressure-sensitive adhesive 2 is reduced, the work of attaching and detaching the plastic film 3 The work efficiency can be improved by simplifying the work of applying or removing the peelable pressure-sensitive adhesive 2.

In the above embodiment, the plastic film 3 is made of polyurethane, polyimide,
Nylon, polyethylene, polypropylene, polycarbonate or plasticized vinyl chloride can be used.

Further, a tackifier or a softening agent may be added to the plastic film 3, and as the tackifier, rosin, rosin ester, chroman resin, terpene resin, hydrocarbon resin, oil-soluble phenol resin, etc. are softened. As the agent, fatty acid ester, animal or vegetable oil, wax, petroleum heavy fraction, etc. can be appropriately used in combination depending on the material of the plastic film 3, and further, a filler, a pigment, an antiaging agent, a stabilizer and the like are blended. be able to.

Further, for a portion having a relatively small protective area such as the front and rear fenders, a plastic film 30 having a layer of the re-peelable pressure-sensitive adhesive 2 similar to the conventional example may be used together. .
