Description

Plastic card using mother pieces and its manufacturing method {PLASTIC CARD USING MOTHER-OF-PEARL AND FABRICATING METHOD THEREOF}

The present invention relates to a plastic card using a mother piece, and more particularly to a plastic card and a method of manufacturing the same for inserting a mother-of-pearl which takes advantage of the natural mother-of-pearl in a plastic card to reliably plant an image as an advanced card. It is about.

First, a first conventional technology as a method of manufacturing a general plastic card will be described with reference to FIGS. 1 and 2.

First, referring to Figures 1 and 2, when describing the conventional conventional plastic card and its manufacturing technique, as shown in an exploded perspective view of the plastic card of Figure 1, such a card is a front transparent synthetic resin sheet of PVC material (10) ), Front printed sheet 20, white sheet 40, rear printed sheet 30, and rear transparent synthetic resin sheet 11, and these cards are transparent synthetic resin sheet 10, front printed sheet in a matching process. 20, the white sheet 40, the back printing sheet 30, and the back transparent synthetic resin sheet 11 to which the magnetic strip 110 is attached are temporarily bonded together.

Referring to the press forming process of such a card with reference to Figure 2, in the above-described laminating process, the matching is completed by heating the sheet at the appropriate temperature and press pressure through the mold press (120, 130) and the heater 140 and bonded by press The work is done. In addition, such a card is cut into a sheet of a card by pressing the sheet after the punching process in the punching process, and the hologram and the sign plate for preventing forgery and alteration on a part of the surface are stamped at a constant pressure and temperature in a stamping process. And inspection and packaging processes.

On the other hand, in recent years, for the forgery of credit cards by inserting a material of various materials in a part of the plastic card, but the high-quality adhesive or material other than the plastic has appeared a lot of problems in the adhesion and durability, the mother-of-pearl The plastic card manufacturing technology used is made by attaching a hot melt adhesive to a thinly processed mother-of-pearl and pre-bonding it to a printing sheet and heat-pressing it to get stuck inside the card body to prevent it from protruding to the surface, and at the same time, it is not inconvenient to use in various terminals. It is done.

By the way, plastic cards using natural mother-of-pearl have been tried by various card manufacturers, but problems occur in the method of bonding mother-of-pearl to the plastic and durability of mother-of-pearl breaking, and mother-of-pearl protrudes over the card, causing problems in using the terminal. There was a limit to the card production.

Therefore, the second prior art to solve the problems of the first prior art, by attaching a hot melt adhesive to the natural mother-of-pearl in the card manufacturing method of expressing the image by printing the unique design of the card as in the prior art, the problem of adhesion By applying the primer varnish on the printed sheet to which the mother-of-pearl is bonded, the mother-of-pearl and the front transparent PVC sheet are adhered to each other to deliver a clear natural mother-of-pearl effect compared to a plastic card using a simple adhesive. The present invention provides a plastic card and a manufacturing method using natural mother-of-pearl, which can reduce the defect rate of the card and reduce the working time by the strong bonding.

As shown in FIGS. 3 to 6, the front holographic plastic card using the hologram foil to which the second prior art is applied, the front synthetic resin transparent sheet 10 and the holographic transfer sheet 60 under the front synthetic transparent sheet 10 After the varnish (70) is coated on the UV printing and the holographic printing sheet 100 coated with a urethane adhesive, and the back printing sheet (30) to match through the adhesive glue on the holographic printing sheet (100) And, it is bonded to the thermosetting adhesive on the back printing sheet 30, the magnetic strip 110 and the sign plate 150 is composed of a transparent synthetic resin sheet 11 that can be printed.

3 to 6, the holographic foil sheet 50 using the second holographic foil sheet 50 of the prior art will be described in more detail. The holographic foil sheet 50 is laminated on the PVC white sheet 40. Thermal transfer through.

Next, as shown in FIG. 4, the primer varnish 70 is coated on the hologram transfer sheet 60 to which the hologram foil sheet 50 is transferred through silk printing, which is a surface of the hologram transfer sheet 60. It is made of a silver metal component to prevent the ink from forming in the case of UV printing and to prevent the occurrence of bleeding, but also to play a role of making the image of the hologram well visible to the user, the urethane adhesive (90) The UV printing layer 80 and the synthetic resin transparent sheet 10 serves to bond the cross-linking role.

Next, as shown in FIG. 5, the front synthetic resin transparent sheet 10, the rear printing sheet 30, and the rear synthetic transparent sheet 11 to which the magnetic strip 110 is attached, have a hologram transferred and a printed layer. The holographic printing sheet 100 and the laminating process to be bonded using a thermosetting adhesive. Each sheet is placed between the planar lower mold 130 and the planar upper mold 120 and laminated by applying a heat of 155 ° C. to the heater 140 at a pressure of 17 kg / cm 2 for 15 minutes.

Thus, the front synthetic resin transparent sheet 10, the hologram is transferred to the holographic printing sheet 100 having a UV printing layer, the rear printing sheet 30, and the rear synthetic resin transparent sheet 11 is attached to the magnetic strip (110) When laminating the adhesive glue layer is generated between the sheets (10, 100, 30).

As a result, according to the second conventional technology, the holographic foil sheet 50 is adhered to the white sheet 40 through thermal transfer to secure the adhesive force between the holographic foil sheet 50 and the white sheet 40 and a primer. The varnish 70 enables UV printing and the urethane adhesive 90 enables adhesion between the UV printing layer 80 and the front synthetic transparent sheet 10 and at the same time changes the hologram image or color. The back hologram effect is fully shown.

As described above, the magnetic sheet 110 and the signature plate 150 are bonded to the lower synthetic resin sheet 11, the rear printing sheet 30, and the upper synthetic resin sheet 10, and the printed sheet on which the hologram is transferred ( An example of a configuration in which 100) is bonded using laminating is shown in detail in FIG. 6.

Therefore, the front hologram plastic card that can be shipped as a more advanced card in a relatively simple manufacturing process than the conventional plastic card was possible.

However, the above-described second plastic card of the prior art also uses a thin film hologram to the last and is insufficient to give a luxurious pattern and luster peculiar to natural mother-of-pearl. When the mother pieces having a considerable thickness are embedded in the plastic card in a general manner, the thermal expansion rate and strength of the mother pieces are different, so that the plastic sheet and the metal pieces are peeled off at a high temperature or when the card is bent, which causes problems in durability. In addition, even if the mother-in-law is successfully inserted into the card, there is a problem that the luster unique to the mother-of-pearl disappears when the transparent resin sheets 10 and 11 are coated thereon.

However, in recent years, ultra high-end cards ranging from several hundred thousand won to one hundred thousand won are being released. In some cases, gold is coated on the outside by applying irregularities to existing plastic cards, depending on the need for more luxury cards. Of course, since the gold coating peels off with frequent use, there is still a need in the industry to solve the problem.

The present invention has been made in order to solve the above problems, the object of the plastic card is to ensure the durability, while utilizing the natural mother-of-pearl in the plastic card as a generally uncomplicated process, while also utilizing the unique luster of natural mother-in-law To provide.
