The present invention relates to a method for manufacturing a plastic card sheet, and more particularly, amethyst powder is contained in the sheets constituting the plastic card so that far-infrared rays and anions, which are beneficial to the human body, may be released to promote the health of the card holder. It relates to one invention.

In general, a plastic card is a kind of plastic money issued to a certain member for deferring the collection of goods and services for a certain period of time. The card is mainly a credit card or a cash card. It is widely used as a cash card, transportation card, medical card, membership card, etc. In Hyundai, various kinds of plastic cards differentiated according to customers' credit ratings are provided to customers.

Such plastic cards are mainly made of cards having a thickness of about 0.8 mm by laminating four to six thin synthetic resin sheets and thermally bonding them, and are mainly coated on top, top, core, bottom, and bottom coated papers. It is thermally bonded in a state where the backs are stacked one by one to form one plastic card.

The upper and lower printing papers constituting the plastic card are configured to dry after printing with ink and laminated on the card. At this time, the printing process is performed by mixing mineral powder with anion or far-infrared radiation in ink during printing. Functional cards have been proposed.

However, as described above, the conventional functional cards for mixing and printing the mineral powder into the ink have a problem such that the adhesion of the ink is remarkably lowered as the mineral powder is mixed into the ink, resulting in a large amount of poor printing. After the sheets were thermally bonded, a closed end occurred such that the sheets were separated from each other due to external conditions such as temperature change or bending of the card.

Therefore, if the mixing ratio of mineral powder is lowered, the emissivity of anion and far infrared rays is remarkably lowered, so that the desired health promotion effect can not be obtained, and the time required to properly control the mixing ratio of minerals in printing is required. As a result, the productivity of card manufacturing could not be improved.

The present invention has been made in view of the above-mentioned problems, and its object is to contain amethyst powder in the sheets constituting the plastic card so that far-infrared rays and anions are released to the human body, thereby promoting the health of the card holder. It is to provide a method for producing a sheet for.

Features of the present invention for achieving the above object, the top coated paper, the top printing paper, the core sheet, the bottom printing paper, the bottom coating paper and the like are laminated in a state in which the laminated sheet of each sheet constituting a single plastic card In the manufacturing method, 73 to 78% by weight of a synthetic resin raw material in a fine powder state having a particle size of 800 mesh or less, 14 to 17% by weight of amethyst powder having a particle size of 2,000 mesh or less, 4 to 5% by weight of a plasticizer, Preparing 4 to 5% by weight of a stabilizer; Adding the raw materials to a stirrer and mixing the mixture evenly for 30 to 40 minutes; An extrusion molding step of inserting the evenly mixed raw materials into an extruder, heating and melting them to a temperature of 160 to 190 ° C, and extruding the melted raw materials through a die by extruding with a screw; A calender processing step of rolling the melted raw material by extrusion molding while continuously passing between the pressure rollers to form a thin sheet-like sheet; Stacking the thin sheets formed by calendering and cutting them to a standard; Cut and completed sheets are to be achieved by the manufacturing method of the plastic card sheet, characterized in that at least one of the top coated paper, the top printing paper, the core sheet, the bottom printing paper, the bottom coating paper constituting the plastic card. It can be.

Example

As shown in FIG. 2, the plastic card 1 according to the present invention includes an upper coated paper 12a, an upper printing paper 11a, a core sheet 10, a lower printing paper 11b, and a lower coated paper 12b. The same plurality of thin sheets are thermally bonded in a state of being laminated in order to form a single plastic card, and the present invention relates to a method of manufacturing the sheets.

That is, 75 weight% of synthetic resin raw materials of the fine powder state which have a particle size of 800 mesh or less, 15 weight% of the amethyst powder which has a particle size of 2,000 mesh or less, 5 weight% of a plasticizer, and 5 weight% of stabilizer were prepared.

The synthetic resin raw material was used to purchase a PVC raw material made of fine powder through a synthetic resin manufacturing company.

The amethyst powder was used to obtain a quality Korean amethyst of high quality, pulverized into a fine powder through a pulverizer and collected by collecting through a filter dust collector, and mainly used to collect the fine powder particles scattered inside the sealed tank After collecting the generated electric dust collector was collected through a bag filter (bag filter).

Since the technique of capturing fine powder using the above-mentioned electric dust collector and a bag filter is already widely used in the technique of collecting and collecting the powder, its detailed description is omitted.

The plasticizer is added to the PVC raw material to increase the thermoplasticity to facilitate the molding of the raw material at a high temperature as a liquid DOP (dioctylphthalate) is used here.

The stabilizer is a chemical agent added to prevent or inhibit deterioration of the PVC raw material, and prevents photo deterioration and oxidation deterioration due to light and oxygen generated when the molded product is used for a long time. Or as used to inhibit the polymerization inhibitors (heavy compound) such as hydroquinone or catechol is used here, but the resin stabilizers used in PVC is very diverse and many types, so the present invention is not limited to the type of stabilizer no.

In some cases, a small amount of processing aid (Specialty PVC Resin) or impact modifier (BTA) may be added as other additives in addition to the plasticizer and the stabilizer to improve the mixing and durability.

Subsequently, the raw materials were put into a stirrer and mixed evenly for about 30 minutes.

The stirrer allowed the mixture to be evenly blended using a conventional stirrer in which stirring blades mounted inside the tank were slowly rotated by the power of a motor.

Subsequently, evenly mixed raw materials were introduced into an extruder, heated to a temperature of about 170 ° C., melted, and extruded with a screw to discharge the melted raw materials through a die.

Subsequently, calender processing was performed in which the raw material melted by extrusion molding was rolled while continuously passing between the pressure rollers to form a thin sheet-like sheet.

Subsequently, the thin sheets molded by calendering were stacked, cut to size, and then packaged to complete the manufacture of the sheets.

The sheets were mainly formed into sheets having different thicknesses between 0.08 and 0.4 mm, the core sheet 10 was 0.35 to 0.4 mm, and the upper and lower printing papers 11a and 11b were 0.12 to 0.16 mm, The upper and lower coated papers 12a and 12b used a thickness of 0.08 to 0.09 mm.

The sheet completed by the manufacturing method of the present invention is the upper coated paper 12a, the upper printing paper 11a, the core sheet 10, the lower printing paper 11b, the lower coating paper 12b constituting the plastic card (1). At least one sheet may be used, but in consideration of the thickness and position of the sheet, it is preferable to use two sheets of upper and lower printing sheets 11a and 11b.
