Abstract

PURPOSE:To keep a gluing part to the minimum necessity, prevent the glue remnant or contamination as much as possible and obtain the better work efficiency and finishing appearance by attaching a double faced adhesive tape previously on only parts which are needed for fixing on a vehicle or packaging film, and packaging necessary areas of the vehicle by the packaging film. CONSTITUTION:For a double faced adhesive tape to be used, a tackiness agent layer on the side to come into contact with the coated surface of a vehicle is formed with a restripping type tackiness agent made of a silicone glue, acrylic glue, etc. with an excellent heat resistance and weather resistance, and the one with more than 3 layer structure including a core material is preferred. As a core material, it is preferable to use a material with plasticizer resistance such as polyester film, etc. For a tackiness agent on the side to come into contact with the packaging film, the holding of the film for a long period of time and fixing efficiency are important, so a partial usage of adhesive may be possible. As a packaging film, a various types of materials can be used. For example, the usage of a material with elasticity such as polyvinyl chloride, nonwoven fabric, etc. is preferable. Also, a previously molded material into a curved shape may be used.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a method for packaging a vehicle.

[Conventional technology] Conventionally, when cars that have just been produced at a factory are stored outdoors or transported to a dealership, etc., it is necessary to prevent dirt and scratches on the car body, as well as to prevent corrosion caused by the outside air. To achieve this, various methods are used to protect the exterior of automobiles.

Conventionally, the following methods have been used to protect automobiles.

■ Protect the exterior of your car with wax-like removable paint.

■ Temporarily cover a car with a heat-shrinkable synthetic resin film and shrink-wrap the entire car by heating it (
(See Japanese Patent Publication No. 50-18837).

■ Temporarily cover a car with a thermoplastic synthetic resin film and wrap it by heating and pressurizing it from the outside.
(See Publication No. 315).

(2) A car is temporarily covered with a thermoplastic synthetic resin film, and the inside of the resin film is suctioned under reduced pressure to wrap the entire car in a skin pack (see Japanese Patent Laid-Open No. 53-55292).

■ Attach the entire surface of the adhesive-treated packaging film to the exterior of the car by hand.

[Problems to be Solved by the Invention] However, the above-described conventional method for protecting the exterior surface of a vehicle has the following drawbacks.

■ Application of removable paint has the disadvantage that it requires a great deal of effort to remove the paint, making it difficult to work with, and that windows, tires, etc. are prone to staining due to sagging during paint application.

- Shrink packaging requires large equipment including a heating device for packaging, requires a considerable amount of heat, and is therefore expensive, and is difficult to handle for opening/closing parts such as doors and bonnets.

■ Similar to (■) above, with heat and pressure packaging, it is difficult to deal with the opening and closing parts, and since it is full-face packaging, there is a space between the windshield and the packaging film, making it extremely difficult to operate when moving. becomes difficult.

■ Although skin pack packaging has good workability, it has the disadvantage that air bubbles tend to remain on the uneven surfaces of the car, and that air bubbles tend to leave behind after the packaging film is removed.

■ The method of pasting a packaging film that has been treated with adhesive on the entire surface is difficult to work with and takes time, and since the entire surface is treated with adhesive, the peeling force becomes heavy over time, and problems such as adhesive residue and contamination occur. It's easy to do.

The present invention improves the problems of the prior art, and provides a vehicle packaging method that is easy to work with and that minimizes the occurrence of adhesive residue or contamination on the exterior paint film of the vehicle. It is intended to.

[Means for Solving the Problems] In other words, the present invention provides, when wrapping a vehicle with a packaging film, a method for fixing the vehicle and the packaging film only in the region of the vehicle that requires wrapping. Alternatively, double-sided adhesive tape is applied in advance to only the portions of the packaging film necessary for fixing the vehicle and the packaging film on one side, and then the vehicle and the packaging film are bonded together using the double-sided adhesive tape. It is characterized by being wrapped while being fixed on the other side.

The double-sided adhesive tape used in the present invention must not leave adhesive residue or contamination when the packaging film is re-peeled, even after severe conditions such as when vehicles are exposed outdoors for long periods of time in the summer. Yes, the adhesive layer on the side that comes into contact with the painted surface of the vehicle is made of a removable adhesive made of silicone glue, acrylic glue, etc. with excellent heat resistance and weather resistance, and has a structure of three or more layers including a core material. is good.

In addition, in order to prevent substances contained in the packaging film, such as plasticizers and resins, from passing through the double-sided adhesive tape and transferring to the painted surface of the vehicle, a durable material such as polyester film is used as the core material for the double-sided adhesive tape. It is desirable to use a material with plasticizer properties.

Furthermore, the adhesive on the side that comes into contact with the packaging film does not need to be re-peeled, and long-term retention and fixation of the packaging film are important, so a permanent adhesive type is preferable. It is also possible to use some agents.

In the present invention, the portions to which the double-sided adhesive tape is attached are only the portions necessary to at least fix the vehicle and the packaging film. In addition, to prevent rainwater and dust from penetrating the surface of the vehicle when the vehicle is exposed to the wind and rain, the areas that require packaging such as the sides, ceiling, bonnet, and doors of the vehicle are sealed with packaging film. It is preferable to stick it around the area.

Double-sided adhesive tape can be attached in advance to the parts of the vehicle that are required for fixation as described above, or it can be attached to the outer periphery of packaging film that has been cut to match the shape of each part of the vehicle body. good.

After this, the packaging film is cut to match the shape of each part of the vehicle body and is fixed to the other adhesive layer of the double-sided adhesive tape attached to the vehicle side, or the above-mentioned double-sided adhesive tape is attached in advance. The wrapped packaging film is attached and fixed to the vehicle for packaging. At this time, it is preferable to limit the number of packaging films cut into the shapes of each part to the minimum required number, since if there are too many, the workability will deteriorate.

The packaging film used in the present invention can be made of various materials, but it is difficult to attach the packaging film to curved surfaces such as corners, so
For example, it is preferable to use a stretchable material such as a polyvinyl chloride film or a nonwoven fabric, and a material preformed into a curved shape may also be used.

Specific packaging film materials include paper, cloth, synthetic paper, synthetic leather, or composite materials thereof, polyolefin resins such as polyethylene, polypropylene, polyethylene-vinyl acetate copolymer, and nylon. , vinylon, polyester, polyurethane, ionomer resin, vinylidene chloride resin, polystyrene, polycarbonate, acrylic resin, and composites thereof, as well as fluororesin, polyimide, polyamideimide,
Examples include various materials such as polyether sulfone.

In addition, the packaging film can be subjected to printing, embossing, or other treatments as needed to improve its appearance.

[Operation] By applying double-sided adhesive tape in advance only to the parts necessary for fixing the vehicle or packaging film, and wrapping the necessary parts of the vehicle with the packaging film, the area to which adhesive tape is applied can be kept to the minimum necessary. can do. Therefore, it is possible to prevent adhesive residue and contamination as much as possible. In addition, since the double-sided adhesive tape is attached to the vehicle or packaging film in advance, curved surfaces can be fixed in a series of operations while applying tension to the packaging film, making it easier to work with other parts and packaging. The subsequent appearance finish will also be good. Furthermore, since the packaging does not cover the entire surface of the vehicle, it is easy to handle opening/closing parts such as doors.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Example 1 (Manufacturing example of double-sided adhesive tape) First, as shown in FIG. 3, acrylic rubber 2-pole At? '51 (product name, manufactured by Nippon Zeon ■) dissolved in toluene has a thickness of 20 mm after drying.
The adhesive layer 2 was applied on the packaging film side. Next, a core material 3 made of a polyethylene terephthalate film with a thickness of 25 μm coated with an undercoat 4 on both sides is layered on this packaging film-side adhesive blue agent layer 2, and the above-mentioned acrylic rubber solution is further applied on top of the core material 3 after drying. The thickness of
The vehicle side adhesive layer 5 is formed by applying the coating to a thickness of μm.
It was dried to produce a double-sided adhesive tape 6.

(Vehicle packaging example) Using the above-mentioned double-sided adhesive tape cut to a width of 30III11, first, as shown in FIG. The vehicle side adhesive layer 5 of the double-sided adhesive tape 6 was pasted around the area 12 and around the area 13 from the rear seat door to the upper part of the rear fender. Further, as shown in FIG. 2, double-sided adhesive tape 6 was similarly applied around the ceiling section 14, the bonnet section 15, and the trunk section 16 of the vehicle 10. The double-sided adhesive tape was attached at the periphery of each packaging area of the vehicle 10 so that each area was sealed with a packaging film.

Next, a packaging film with a thickness of 70 μm made of soft polyvinyl chloride containing 30% by weight of a polymeric plasticizer, which has been cut in advance to fit the shape of each packaging area, is wrapped with double-sided adhesive tape 6 to avoid wrinkles. It was attached and fixed to the packaging film side adhesive layer 2, and the vehicle was packaged.

Vehicles packaged in this manner had doors that could be opened and closed freely, no similar problems with self-propulsion, and a good exterior finish.

Next, the results of the weather resistance test (table evaluation) of the double-sided adhesive tape produced in the above production example will be explained.

The above-mentioned double-sided adhesive tape was attached to a painted board test piece (acrylic paint), and after covering it with the above-mentioned soft polyvinyl chloride resin film, it was exposed to an ultraviolet weatherometer for 100 hours and 200 hours, and the adhesion during re-alignment and separation was evaluated. The adhesive residue of the agent, contamination, and the condition of the coating film on the test piece were evaluated. The results are shown in Table 1.

Further, for comparison with the double-sided adhesive tape used in this example, similar tests were conducted using commercially available acrylic double-sided tape and rubber double-sided tape, respectively. The results are also shown in Table 1.

(Vehicle packaging example) Using the above double-sided adhesive tape cut into widths of 30II and 11, it was pasted around each packaging area of the vehicle in the same manner as in Example 1. 157zm on one side of 35g/M2)
A packaging film coated with a polyethylene laminate (blue) was fixed by pasting one adhesive layer on the packaging film side of a double-sided adhesive tape in the same manner as in Example 1, and packaging was performed.

In this example as well, the finished appearance was good.

In addition, the double-sided adhesive tape and nonwoven fabric with polyethylene laminate produced in this example were also tested for weather resistance (table evaluation) using test pieces coated with acrylic paint and polyester paint in the same manner as in Example 1. I did it.

The results are shown in Table 2.

(Margins below) ¥1 Figure Figure 2 [Effects of the invention As explained above, the vehicle packaging method of the present invention is a method in which the packaging film is fixed to the vehicle using double-sided adhesive tape only in the necessary parts. Compared to full-surface application, it is also easier to work with, for example, on curved surfaces, and produces a good finish with fewer bubbles and wrinkles during application. In addition, since the double-sided adhesive tape is in partial contact with the painted surface of the vehicle, there is less adhesive residue and contamination on the paint film.
It also has excellent storage stability on the exterior of the vehicle after the packaging film is peeled off.
