Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a decorative strip made of synthetic resin with excellent aesthetics that can be attached to the surface of vehicles, furniture, etc. to enhance the decorative value of the design while also serving a reinforcing role.

(Prior Art) This type of decorative band generally uses a constituent material mainly composed of vinyl chloride resin in order to provide it at low cost. Products mainly composed of vinyl chloride resin have the disadvantage that their metallic luster deteriorates during long-term use, or they are subject to severe peeling and discoloration.
Therefore, a decorative band is known in which an ionomer resin film with the same effect is provided on the uppermost surface of an ionomer resin covering sheet used on the surface and a glitter tape embedded inside. (For example, Japanese Utility Model Application Publication No. 61-62099) (Problem to be solved by the invention) In the conventional technology, the bonding between the adherend sheet and the bright tape is integral and strong, and the temperature The effect of preventing contraction and expansion in response to changes is recognized. However, the ionomer resin used in conventional glitter tape has very poor fluidity, making it difficult to create a thin resin film.
There was also the problem that the brightness appearing on the surface of the lower metal vapor deposited film was extremely poor, and the bright tape itself was difficult to bend because the ionomer resin film had poor bendability. In addition, the metal evaporated film of aluminum or the like used in the conventional bright tape has a problem in that the metal photoresistivity is greatly deteriorated due to oxidation of the aluminum.

This idea was made in view of these conventional problems, and its main purpose is to:
The surface of the decorative strip retains its luster beautifully for a long period of time, and by using an ethylene copolymer resin sheet inside the glitter tape embedded inside the decorative strip, it is able to adhere to the metal vapor-deposited film. The improved elasticity prevents the metal vapor deposited film from peeling off, and the entire decorative band is flexible, has excellent bendability, and does not cause wrinkles.
The purpose of this invention is to provide a decorative band whose purpose is to maintain photosensitivity over a long period of time by means of a double layer of metal vapor deposition.

(Means for Solving the Problems) In order to achieve the above object, this invention consists of a decorative strip main body 1 consisting of a surface adhesive sheet 2 of ionomer resin, an internal glitter tape 5, and a base sheet 3 of vinyl chloride. It has been done. This bright tape 5 has
An ethylene copolymer resin sheet 11 that is compatible with the ionomer resin is provided on the top, and an aluminum metal vapor-deposited film 8 is provided on both the front and back sides of the bottom surface.
The polyester film 7 coated with 9 is polymerized. Ethylene and
A co-polymer resin sheet 12 has been polymerized. A vinyl chloride sheet 13 is polymerized and adhered to the lower surface of this ethylene copolymer resin sheet 12 via an adhesive 10. Then, the vinyl chloride sheet 13 and the substrate sheet 3 made of vinyl chloride are integrally fused.

This decorative band body 1 uses the bright tape 5 inside as a medium to reliably maintain the beautiful brightness of the surface for a long period of time, and the ethylene-based intermediate portion of the bright tape 5 embedded inside the decorative band body 1 is
The copolymer resin sheets 11 and 12 firmly adhere the metal deposition film, and the product as a whole is flexible and has good bendability.

(Function) The decorative band of this invention has the above-mentioned structure,
To use this decorative band on vehicles, furniture, architecture, etc., attach adhesive tape or various adhesives to the back side of the substrate sheet 3 and adhere it to the object to be attached. The metal vapor-deposited films 8 and 9 of aluminum or the like of the bright tape 5 create a deep metal shine over a long period of time, increasing the decorative value, and also make the decorative band body 1 easy to bend and prevent wrinkles from forming. It is something.

(Example) An example of this invention will be explained with reference to the drawings.
The decorative band main body 1 is made of synthetic resin and is molded into a longitudinal band shape, and has an adhesive sheet 2 on the surface made of ionomer resin, a bright tape 5 embedded inside, and a vinyl chloride layer underneath the bright tape 5. It is integrally molded with a substrate sheet 3 consisting of the following.

A transparent ionomer resin is used for the adherend sheet 2, and downwardly bent pieces 6, 6 are formed on both sides in the longitudinal direction so as to cover both sides of the bright tape 5. It's summery. Next, the bright tape 5 is provided with an ethylene copolymer resin sheet 11 having compatibility with the ionomer resin at the top. On the lower surface of this ethylene copolymer resin sheet 11, a metal vapor deposited film 8 and a metal vapor deposited film 9 of aluminum are respectively deposited on both the front and back sides of the polyester film 7. An ethylene copolymer resin sheet 12 is polymerized and bonded to the lower surface of the metal vapor deposited film 9 located below the polyester film 7. A vinyl chloride sheet 13 is polymerized on the lower surface of the ethylene copolymer resin sheet 12 with various adhesives 10 interposed therebetween. This vinyl chloride sheet 13 is firmly and integrally polymerized and bonded to a substrate sheet 3 made of vinyl chloride resin of the same quality.

(Effects of the invention) Since this invention is configured as described above, it has the following effects. That is, according to this decorative band, the merits and benefits of each type of synthetic resin, which are incompatible with each other, are demonstrated using a glitter tape embedded inside an adhered sheet of ionomer resin, which has excellent transparency and durability. It has the effect of molding the whole thing firmly and integrally by utilizing it. In addition, the ethylene copolymer resin inside the bright tape is flexible and easy to bend, so it has the effect of bonding well with the metal vapor deposited film. In addition, this decorative band has the effect of reliably preventing rainwater from entering through the joint with the glitter tape buried inside, and also protecting the glitter tape from discoloration. By providing the ethylene co-polymer resin sheet on the top of the bright tape, it is compatible with the ionomer resin of the adherend sheet, so the bonding surfaces of the two are firmly fused and integrated. It has the effect of In addition, since the ethylene copolymer resin film is used on the top and bottom of the bright tape, it has very good fluidity with respect to the metal evaporated film, and a thin resin film can be easily formed to provide sufficient coverage. It has the effect of protecting the metal deposited film. Furthermore, since the ethylene copolymer resin film is more flexible than the ionomer resin, it has excellent bendability and extensibility, and has the practical effect of being extremely bendable even at corner portions and free from wrinkles. Furthermore, since the glitter tape has a structure in which a metal vapor-deposited film of aluminum is coated on both the front and back sides of the polyester film located inside the glitter tape, it produces a brighter and darker shine for a longer period of time than with conventional single-layer metal vapor-deposit films. Each metal vapor deposited film is protected by an ethylene copolymer resin sheet with good fluidity on its surface, so there is no need to worry about oxidation or contamination. In addition, since the vinyl chloride sheet at the bottom of the bright tape is polymerized with the vinyl chloride substrate sheet, the two are firmly welded and bonded, which has the excellent effect of integrally bonding the whole.
