Description

[Detailed description of the invention] This invention relates to a decorative band made of synthetic resin that is adhered to the surfaces of vehicles, architecture, furniture, etc. to increase the decorative value of the design and maintain beauty over a long period of time. It is something.

Conventionally, this type of decorative band generally uses a constituent material mainly made of vinyl chloride, which can be provided at low cost. However, this vinyl chloride-based material has drawbacks such as deterioration in brightness and discoloration during long-term use.

In addition, when a glitter tape is integrally molded with a vinyl chloride band on the outer periphery except for a part of the surface, there is a drawback that rainwater gradually infiltrates from the joint between the glitter tape and the band. The inside of the tape becomes contaminated, resulting in a very unsightly decorative band.Also, with the polyester tape used as the core of conventional glitter tape, which is coated with aluminum, the fusion bonding strength is uneven during molding. The disadvantage is that the aluminum vapor deposited surface undergoes a chemical change from the longitudinal ends, becoming aluminum hydroxide, which disappears and makes the product look very unsightly.

This invention is an attempt to solve the above-mentioned drawbacks, and is made by firmly adhering ionomer resin, which is relatively expensive and incompatible with vinyl chloride, which has excellent brightness over a long period of time, to the surface of the decorative band. At the very least, it is intended to make the decorative band permanently beautiful and to prevent it from shrinking and expanding due to temperature changes. Also,
The purpose of this invention is to obtain a decorative band with excellent brightness for a long period of time by using an aluminum foil sheet of glitter tape embedded inside the decorative band.

Its main structure is that the decorative band is formed from a surface sheet made of ionomer resin, a glitter tape embedded inside, and a base sheet made of vinyl chloride, and the glitter tape is provided with an aluminum foil sheet inside. At the same time, an ionomer resin film compatible with the adherend sheet is superposed on its upper surface. Further, a vinyl chloride sheet that is compatible with the base sheet is adhered to the lower surface of the aluminum foil sheet through an adhesive. Therefore, according to this decorative band, incompatible synthetic resins can be easily integrated using the internal glitter tape as a medium by replacing the material of the glitter tape, which has the effect of strengthening the whole and the effect of the glitter tape. By interposing an aluminum foil sheet inside, the metallic luster is maintained for a long period of time. In addition, the main body of the decorative band is made of inexpensive vinyl chloride, and the top sheet is made of an expensive ionomer resin with excellent brightness, making the product extremely inexpensive.

Next, an embodiment of this invention will be described with reference to the drawings. A decorative band main body 1 made of synthetic resin is molded into a longitudinal band shape, and a covering sheet 2 made of ionomer resin appears on the surface and is buried inside. Bright tape 4 and base sheet 3 made of vinyl chloride
It is composed of. The adhesive sheet 2 is made of a transparent ionomer resin, and has downwardly bent pieces 5, 5 formed on both sides in the longitudinal direction so as to cover both sides of the bright tape 4.

Further, on both sides of the base sheet 3 in the longitudinal direction,
The bent pieces 5, 5 are formed by forming upward standing pieces 6, 6.
It has a shape that covers it from both sides.

Next, an aluminum foil sheet 7 is placed inside the bright tape 4, and an ionomer resin film 8 which is compatible with the adherend sheet 2 is polymerized thereon.
Vinyl chloride 9, which is compatible with the base sheet 3, is adhered to the lower surface of the aluminum foil sheet 7 through various adhesives 10.

This idea is as mentioned above, and according to this decorative band body, the bright tape embedded inside is used as a medium to utilize the advantages and advantages of two types of incompatible synthetic resins, and the adhesive is used. It is an excellent product that can reliably and firmly mold both synthetic resins into one piece without using them, and prevents them from tearing or peeling at the time of extraction from the mold even if two types of incompatible synthetic resins are heated and extruded, which is a disadvantage of conventional methods. effective.

In addition, this decorative band has the practical effect of reliably preventing rainwater from entering through the joint with the inner glitter tape, thereby reliably protecting the glitter tape from contamination, discoloration, and the like. By providing an ionomer resin film on the top surface of the bright tape and superimposing the ionomer resin film on the surface, welding of the ionomer resins to each other is ensured, and the two are tightly and firmly welded. It has excellent transparency and weather resistance, and protects the aluminum foil sheet from contamination so that it can be used beautifully for a long period of time.

In addition, the vinyl chloride sheet on the bottom surface of the bright tape is integrally bonded to the non-adhesive aluminum foil sheet on the top using an adhesive, so it not only ensures the bonding of the various composite layers of the bright tape, but also ensures the internal Since the adhesive does not come into direct contact with the air, there is no need to worry about it peeling off over a long period of time, and the vinyl chloride of the base sheet and the bottom vinyl sheet, which are the main constituent materials of the decorative band body, can be easily welded and bonded. This has the effect of significantly strengthening the decorative band. In addition, it is practical to use comparatively inexpensive vinyl chloride as a main ingredient and an expensive ionomer resin only in the necessary areas of the topsheet to provide a decorative band at a significantly low cost. Furthermore, the aluminum foil sheet embedded inside the bright tape eliminates the inaccuracies caused by the fusion bonding and strength during molding, which is the case with aluminum vacuum-deposited on the polyester tape that is the core of the conventional bright tape. At the same time, it has an excellent effect that has not been found in the past in that the aluminum vapor-deposited surface undergoes a chemical change from the longitudinal end edge, and it eliminates the extremely unsightly defects caused by flaking and spots.
