Abstract

PURPOSE:To enhance decorative value by melting an ethylene copolymer resin layer to laminate the same to the metal vapor deposition layer applied to a synthetic resin film and laminating a vinyl chloride resin sheet to said resin layer to bond the same to the resin layer under pressure and releasing the resin layer to transfer the metal vapor deposition layer and superposing a transparent ionomer resin layer to the surface of the metal vapor deposition layer to bond the same thereto under pressure. CONSTITUTION:A metal vapor deposition layer 3 is applied to the entire rear of a synthetic resin film 2 having smoothness in its longitudinal direction and, next, an ethylene copolymer resin layer 4 is melted to be laminated to the surface of the metal vapor deposition layer 3. Subsequently, a vinyl chloride resin sheet 6 is superposed on the ethylene copolymer resin layer 4 through an adhesive 5 to perform molding. By releasing the synthetic resin film 2, the metal vapor deposition layer 3 is transferred to the ethylene copolymer resin layer 4. Next, a transparent ionomer resin layer 9 is directly applied and superposed on the metal vapor deposition, layer 3 being the uppermost layer to form a bright tape 1. By this method, the tape excellent in brightness and prevented from the tearing of the metal vapor deposition layer or the generation of a spot thereon and also prevented from elongation at the time of molding can be obtained.

Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is a bright tape that is attached to the surface side of the molding currently available in India, which is fitted to the joint between the body panel and the glass panel of various vehicles. The main object of the present invention is to provide a method for producing a bright tape for vehicle window molding, which significantly increases the decorative value of the bright tape expressed on the upper surface of the molding.

(Prior Art) Conventionally, various methods have been used to apply a metal vapor deposition layer to be deposited and buried inside the bright tape used for this type of window molding. .

Namely, (1) a metal vapor-deposited layer made of a metal such as aluminum is formed directly on a longitudinal vinyl chloride sheet, and (2) a metal vapor-deposited layer of various metals is formed on the front or back surface of a polyester tape. What I wore,
As for <<3>>, there are currently known products in which a metal foil tape is interposed instead of the polyester. (Problems to be Solved by the Invention) As mentioned above, among the bright tapes used for conventional molding, in (1), vinyl chloride does not have a smooth surface due to its nature. Even if a metal vapor deposited layer was directly formed, there was a problem in that the brightness was extremely poor and the decorative value was low.In (2), a metal vapor deposited layer was applied to a polyester tape, and there was no problem in heat resistance. However, there is a problem in that polyester tape easily wrinkles when heated and bent at corners, etc., and in the case of bright tape that needs to be widened, many wrinkles occur, significantly detracting from the brightness and decorative value. In addition, in (3), the glitter tape that uses metal foil has a problem that the metal foil itself is very thin, so when it is laminated with various resin layers, there is a lot of damage to the metal foil. Wrinkles and spots are likely to occur, and this metal foil tape has a problem in that large and small wrinkles occur at bent portions such as corners, impairing the bright surface.

The present invention was made in view of the problems of the conventional technology, and its purpose is to create a metal vapor deposited layer located inside a glitter tape with good adhesive properties through a simple process. The present invention aims to provide a bright tape for molding that is thinly transferred onto materials, solves all the conventional drawbacks, and has excellent brightness and decorative value.

(Means for Solving the Problems) In order to achieve the above object, the method for manufacturing the glitter tape for molding of the present invention is first of all to provide excellent shine and prevent the occurrence of stains and wrinkles. A metal vapor deposition layer is applied to a smooth resin film such as polyester film or polypropylene using glitter tape.
An ethylene co-polymer resin layer is melt-laminated to this metal vapor deposited layer, and a vinyl chloride sheet is laminated and pressure-bonded to this ethylene co-polymer resin layer via an adhesive. And next, the smooth resin film! The metal vapor deposited layer is beautifully transferred to the surface of the ethylene co-polymer resin layer with excellent adhesive properties by applying the adhesive, and a transparent ionomer resin layer is directly polymerized and pressure-bonded to the surface of the metal vapor deposited layer to form a longitudinal direction. This is a method of manufacturing a bright tape.

Another method is to further polymerize an ethylene copolymer resin layer on the surface of the metal vapor-deposited layer, and then stack and press-bond the transparent ionomer resin layer on top of the layer to produce a bright tape in the longitudinal direction.

Furthermore, in order to protect the vinyl chloride sheet, which is easily deformed by heat during melt lamination and compression molding of the ethylene copolymer resin layer, a heat-resistant protective sheet is removably polymerized on the lower surface of the vinyl chloride sheet. There is a manufacturing method. (Printing) The present invention is a bright tape produced by the above-described manufacturing method, which is integrally embedded in the molding head (l1) of the molding (A) as shown in FIGS.

In the step (d) in FIG. 2, the polymerized resin film (2), which becomes the substrate constituting the metal vapor deposited layer (3), is peeled off to form the ethylene co-polymerized resin film (2) on which the metal vapor deposited layer (3) is polymerized.
This is the process of transferring and adhering to the polymer resin layer (41111).

The step in FIG. 2(e) shows a state in which the metal vapor deposited layer (3) is deposited on the ethylene copolymer resin layer (41) in a planar manner.

In the step (g) in FIG. 2, a transparent ionomer resin layer (9) is integrally applied and polymerized directly to the metal vapor deposited layer (3) on the uppermost surface to give a bright glow. This tape (1) is shaped into a certain shape.

It is something.

<<Effects of the Invention>> Since the present invention is configured as described above, it produces the effects described below.

In other words, according to this method of manufacturing a glitter tape, the metal vapor deposited layer is deposited in a thin mirror-like manner due to the transfer from a polyester or other resin film with good smoothness. In addition to preventing cuts and plaques, it also prevents elongation during ceremonial training. In addition, it has an excellent property of being able to reliably prevent wrinkles, cracks, etc. that occur when a part of a conventional corner is bent, and also sufficiently prevent wrinkles, unevenness, etc., even in corner portions using medium-wide glitter tape.

Furthermore, according to the present invention, there is the practicality that the metal vapor deposited layer is applied to a polyester table, and the metal vapor deposited layer is applied to the polyester table. There is also the effect that the glitter tape is not as thick as it is, and there are no wrinkles caused by slack at the bent corners.

Furthermore, in cases where metal foil is used in place of the conventional metal vapor deposited layer, the metal foil itself easily shrinks against the resin layer.
The present invention has the advantage of being able to satisfactorily solve wrinkles and the like that occur when corners are bent.

By melt-laminating an ethylene co-polymer resin layer on the surface of the metal vapor-deposited layer, the metal vapor-deposited layer deposited on a synthetic resin film such as polyester is completely bonded to the ethylene co-polymer resin layer, which has extremely good adhesion. is transferred firmly and flatly without any unevenness. Furthermore, the transparent ionomer resin layer deposited on the top layer of the bright tape serves to keep the metal vapor deposited layer clean at all times without discoloration or contamination over a long period of time.

Furthermore, by manufacturing a bright tape with a transparent ionomer resin layer on the top surface of which an ethylene co-polymer resin layer is melt-laminated on the top surface of the metal vapor deposition film, oxidation and contamination of the metal vapor deposition layer can be more reliably prevented. Moreover, the transparency and adhesiveness of the ethylene copolymer resin layer can be effectively exhibited, and it can be integrally and firmly bonded to the transparent ionomer resin layer on the surface.

In addition, in the present invention, a protective film that is resistant to ripening is polymerized on the underside of the vinyl chloride sheet in a peelable manner, so that defects such as elongation of the vinyl chloride during the second process can be prevented as much as possible, and accurate bright tape can be used over and over again. There is a characteristic that.
