Description

[Detailed Description of the Invention] (Industrial field of application) The present invention enhances a decorative value excellent in design by adhering to a surface of a vehicle such as an automobile or furniture or the like in a straight or bent position. The present invention relates to a decorative belt made of a synthetic resin, such as a vehicle, which has an excellent aesthetic appearance and can perform a role and a reinforcing role against contact and the like.

(Prior Art) Generally, for this type of decorative strip, a constituent material mainly composed of vinyl chloride resin is used in order to provide it in a good appearance and at a low cost. The constituent material mainly composed of this vinyl chloride resin is used. This vinyl chloride resin-based resin has the drawbacks that it discolors during long-term use, the internal metallic luster deteriorates, and wrinkles occur at the bent portions of the corners, making them unsightly. Therefore, a decorative band is known in which an ionomer resin adhered sheet used on the surface and an ionomer resin film having the same effect are provided on the uppermost surface of the glitter tape embedded inside. (For example, Japanese Utility Model Laid-Open No. 61-62099) In addition, the aluminum vapor deposition film vapor-deposited on the core portion of the polyester film used for the conventional glitter tape embedded in the decorative strip has very excellent glitter. However, it has a drawback that it is easily peeled off due to its very weak vapor deposition force, and it becomes wrinkled to make it dirty, and that it is very weak against bending at the corners.

Further, the vinyl chloride sheet used as the lowermost part of the glitter tape has a problem that cracks and the like occur due to poor elongation of the sheet at room temperature or low temperature.

(Problems to be Solved by the Invention) The ionomer resin used in the glitter tape in the above-mentioned conventional technique has extremely poor fluidity of the material, and it is difficult to form a thin resin film, so that the metal under There was a problem that the brightness that appeared on the surface of the deposited film was extremely poor.

The present invention has been made in view of these problems, and the purpose thereof is to retain the brilliance expressed on the surface of the decorative strip for a long period of time. The ethylene co-polymer resin sheet is used on the upper surface to prevent peeling of the metal vapor deposition film as much as possible, and the vapor deposition power is remarkably enhanced by depositing the chrome vapor deposition film on the lower surface side of the polyester film in the bright tape. Along with
It is intended to provide a decorative strip which prevents wrinkles, unevenness and the like which occur in a polyester film at high temperature due to bending of a corner portion.

Further, a polyurethane sheet is polymerized on the lowermost surface of the glitter tape to obtain heat resistance and decorativeness which remarkably improves stretchability against bending and the like.

(Means for Solving the Problems) In order to achieve the above object, according to the decorative strip of the present invention, the glitter tape (5) located inside the decorative strip (1).
The top surface of ethylene is compatible with ionomer resin.
The co-polymer resin sheet (11) is positioned, and the aluminum vapor-deposited film (8) is vapor-deposited on the upper surface and the chrome vapor-deposited film (9) is vapor-deposited on the lower surface on the lower surface of the ethylene co-polymer resin sheet (11). A polyester film (7) is polymerized. Then, a polyurethane sheet (12) is bonded and adhered to the lower surface of the chrome vapor deposition film (9) via an adhesive (10). A substrate sheet (3) made of vinyl chloride is polymerized and integrated on the lower surface of the polymer urethane sheet (12).

(Operation) The present invention is configured as described above, and in order to use this decorative strip for a vehicle such as an automobile and furniture, an adhesive tape or various adhesives is attached to the back surface of the substrate sheet (3). The metal vapor deposition film of aluminum and chrome on the surface of the adherend sheet (2) allows a heavy metal selection to appear for a long period of time to enhance the decorative value and to enhance the decorative value. It strengthens the bent part and prevents peeling and unevenness of the deposited film.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. A decorative belt (1) formed of a synthetic resin in a longitudinal band shape has an adhered sheet (2) made of an ionomer resin on an outer circumference located on the surface. , A glitter tape (5) embedded in the inside,
It is integrally molded under the glitter tape (5) with a substrate sheet (3) made of vinyl chloride. A transparent ionomer resin is used for the adherend sheet (2). Downward bending pieces (6) on both sides in the longitudinal direction
By forming (6), both side surfaces of the glitter tape (5) are covered.

An ethylene copolymer resin sheet (11) compatible with the ionomer resin is located on the uppermost surface of the glitter tape (5). An aluminum vapor deposition film (8) is vapor-deposited on the upper surface side of the ethylene-co-polymer resin sheet (11), and a chrome vapor deposition film (9) is deposited on the lower surface side.
The polyethylene film (7) vapor-deposited is polymerized. Next, a polyurethane sheet (12) made of a constituent material such as urethane elastomer is polymerized and adhered to the lower surface of the chrome vapor deposition film (9) through an adhesive (10). Further, the substrate sheet (3) made of vinyl chloride is polymerized and adhered to the lower surface of the polyurethane sheet (12) to be integrally molded.

(Effects of the Invention) Since the present invention is configured as described above, it has the following effects. In this decorative strip, the transparency and durability are very excellent, and the glitter tape embedded inside the adherend sheet is used as a medium to utilize the advantages and advantages of each of the incompatible types of synthetic resin to make the whole. It has the effect of firmly and integrally molding. Since the ethylene-co-polymer resin sheet on the top of the glitter tape is compatible with the ionomer resin of the adherend sheet, there is an effect that the joint surfaces of both are firmly joined. In addition, the ethylene-co-polymer resin sheet is more flexible than the ionomer resin and therefore suitable for flexibility and stretchability, and has an excellent effect that it is easily bent even at the corner portion and wrinkles do not occur. Furthermore, by depositing an aluminum vapor deposition film on the upper surface side of the transparent polyester film located inside the glitter tape and a chrome vapor deposition film on the lower surface side, the chrome vapor deposition film has the disadvantage that conventional aluminum has a weak vapor deposition force. It has the effect of reinforcing and preventing peeling of the vapor-deposited film over a long period of time, unevenness and contamination.

Also, by polymerizing and using a polyurethane sheet at the bottom of the glitter tape, it is possible to reliably prevent cracks and the like caused by a conventional vinyl chloride sheet due to its excellent heat resistance and high elongation rate of the sheet itself. There is a practical effect.
