[Industrial applications]

 TECHNICAL FIELD The present invention relates to a bright tape for molding a vehicle for solving unevenness in thickness, wrinkles, and the like that occur on the surface of the bright tape for molding used for vehicles such as automobiles made of synthetic resin.

[0002]

[Prior art]

 Conventionally, as a brilliant tape for this type of molding, a brilliant tape slit to a predetermined width is pasted with a reinforcing film such as polyester, and the reinforced film is peeled off after extrusion molding. However, in this case, the adhesive may remain on the surface of the bright tape, spots, wrinkles, etc. of the applied state of the adhesive may be left on the surface, or the solvent contained in the adhesive may remain and form bubbles. There was a problem of leaving uneven marks on the surface of the glitter tape. Further, the adhesive material tends to have uneven thickness when applied, and this uneven thickness may cause wrinkles and scratches on the surface of the glitter tape when the reinforcing film is peeled off. (See, for example, Japanese Patent Publication No. 3-58898).

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned problems in that the reinforcing film made of polyester or the like is directly adhered to the upper surface of the glitter tape and then peeled off, as described in the prior art. The intended place is to adhere with the polyethylene resin melt-laminated between the fluorine-based resin film and the polyester film so that there is no residue such as coating residue left like the one with an adhesive. The aim is to provide a bright tape for molding that can finish the surface very beautifully.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the bright tape for molding of the present invention comprises a fluororesin film and a polyester film on the upper part of the fluororesin film which is embedded in the molding substrate. Adhesion is made by melting and laminating with resin. A metal vapor-deposited film is applied to the lower surface of the fluorine-based resin film, and a vinyl chloride sheet is bonded to the lower surface of the film with an adhesive interposed between the film and the molded product to be integrated with the molding substrate inside the die during extrusion. It is formed by peeling off the uppermost polyester film and the polyethylene resin. Further, an adhesive is interposed between the polyethylene resin and the polyester film to integrally fix them.

【Example】

 The glitter tape body (1) embedded in the molding base (A) of the vehicle molding of the present invention is mounted on the outside of the vehicle such as wind molding or side molding. The glitter tape body (1) is composed of a fluorine-based resin film (5) in a tetrafluorinated, hexafluorinated copolymer (FEP) film or tetrafluorinated ethylene copolymer (ETFE) film, and its fluorine. The polyester film (7) is melted on the upper surface of the resin film (5) with the molten polyethylene resin (6) by heat and pressure by melt lamination, and the fluorine resin film (5) and the polyester film (7) And are polymerized and adhered by melt lamination with the polyethylene resin (6). After the above steps, a metal vapor deposition film (4) of aluminum, chromium or the like is applied to the lower surface of the fluorine resin film (5), and various adhesives (3) are interposed on the lower surface of the metal vapor deposition film (4). Then, the flexible vinyl chloride sheet (2) is polymerized and laminated.

Next, the glitter tape main body (1) is slit before extrusion molding, and when this glitter tape main body (1) is extrusion molded, the glitter tape main body (1) is polymerized integrally with the vinyl chloride of the molding substrate (1) inside the die. To mold. Immediately after the extrusion molding, or before mounting on a vehicle or the like, the polyester film (7) and the polyethylene resin (6) are peeled off. At this time, since the polyester film (7) is peeled off and the polyethylene resin (6) is also peeled together, the spots, wrinkles and scratches due to the adhesive after peeling do not remain.

Further, in order to improve the adhesiveness between the polyester film (7) and the polyethylene resin (6), the polyester film (7) is previously coated with an adhesive to melt the polyester resin (6). It may be laminated. In addition, fluorine-based resin films such as tetrafluorinated, hexafluorinated copolymer (FEP) or tetrafluorinated ethylene copolymer (ETFE) used in the present invention, and fluorine-based resins conventionally used. The tensile elongation with vinylidene fluoride (PVDF) is as follows. Resin name PVDF FEP ETFE Tensile elongation (%) 150 400 420 According to the above, there is a point that the fluorine-based film is stretched at the time of the metal vapor deposition film when the glitter tape body (1) is manufactured and the vapor deposition cannot be performed neatly.

[0008]

[Effect of device]

 As described above, according to the bright tape for molding of the present invention, the molding base and the main body of the bright tape are integrally molded at the time of extrusion molding, but the polyester film on the surface side of the bright tape heats the molding tape. In addition to the effect of being able to achieve sufficient protection at the time of peeling, it is possible to form a melt-laminated polyester resin between fluorine-based resins without sticking the fluorine-based resin polyester film with an adhesive when peeling. By sticking them together, there is no fear of leaving marks such as spots, wrinkles, etc., that remain after peeling off as if an adhesive was interposed. In addition, when the glitter tape is used, the top polyester film and polyethylene resin are peeled off, so that a fluorine resin film with a large tensile force on the surface causes wrinkles, etc. at the corners of the wind molding. There is an effect that does not. Furthermore, since a fluorine-based resin film with a large tensile elongation is used, when the metal vapor deposition film is applied, the fluorine-based resin film stretches and clean metal deposition cannot be achieved. It has the effect that the polyester film having the above can be reinforced and polymerized and adhered before the metal vapor deposition film is applied, so that the metal vapor deposition film can be deposited neatly.
