Description

Manufacturing method of character elastic pad for key ring with virus blocking ability

The present invention relates to a method for manufacturing a character elastic pad for a key ring having a virus blocking ability, and more particularly, to a method for producing a character elastic pad for a key ring having a three-dimensional shape, having a virus blocking ability by releasing chlorine dioxide. .

Character objects (or pads) for key chains are ornaments that are joined by key chains to bags, diary notes, cell phones, school supplies, etc. Initially, they were manufactured only in a two-dimensional planar structure, but recently, three-dimensional three-dimensional objects were made to meet the diverse needs of consumers. The method of manufacturing in structure is in the spotlight.

A character object having a three-dimensional three-dimensional structure includes a base sheet, a foam layer formed on an upper surface of the base sheet to impart a three-dimensional effect, and a printing layer covering the outer surface of the foam layer.

In this method of manufacturing a character object, a PVC sol layer or a protruding layer for embossing is formed in order to enhance a three-dimensional effect.

However, conventional character objects can easily be scratched or cracked due to external impacts when used.In particular, characters whose color layers are located on the surface are easily deformed by the external environment. The accessory effect is disappearing.

Meanwhile, due to rapid environmental changes in the global village such as warming, humanity is exposed to indiscriminate attacks from new pathogens such as new influenza that have not been dealt with. In addition, in the global era, as international exchanges are increasing, the rate of infectious disease infection is rapidly crossing continents and the extent of infection is spreading to the global level. In this era of war with viruses and bacteria, the easiest way to prevent the spread of pathogens at the level of ordinary citizens is to manage the hands, which are the carriers of bacteria and viruses.

Of course, few people are unaware of the importance of handwashing through the constant publicity of the media and health authorities. Nevertheless, the reason why practically does not work well is that there are not so many realistic obstacles. First of all, when there is a need to wash hands realistically, there is no guarantee that there will be a handwashing water supply nearby, and even if you can wash your hands 8 times a day, if you have a guideline that requires you to thoroughly wash your hands 8 times a day for at least 20 seconds, a ``conjunctivitis patient'' It is difficult to practice without. And even if you wash your hands, if you come into contact with an infected object, such as a handle, the previous hand washing is meaningless.

In this respect, it is required to develop a character elastic pad for a key ring that has a decorative beauty and accessory effect that character objects pursue, and has a function of blocking viruses and bacteria.

Referring to Figures 1 to 7, a method for manufacturing a character elastic pad for a key ring having a virus blocking ability according to an embodiment of the present invention, the character pattern printing step (S100); Pressure-sensitive adhesive application step (S200); PVC elastic foam intervening step (S300); Character pattern transfer step (S400); Chlorine dioxide-releasing material arrangement step (S450); And a character elastic pad manufacturing step (S500). The present invention can manufacture a character elastic pad 500 for a key ring having a three-dimensional shape and virus blocking ability by including these steps.

In detail, the step of printing the character pattern portion (S100) is a step of printing the character pattern portion 200 on the transfer sheet 100 on which a release layer (not shown) is formed.

In the step of printing the character pattern (S100), the transfer paper coating layer 110 may be formed by performing urethane or PVC transparent coating on the transfer paper 100. The transfer paper coating layer facilitates printing of the character pattern 200 on the transfer paper 100.

In the character pattern printing step (S100), the printing method may use any one printing method selected from offset printing, sublimation printing, silk screen printing, digital printing, gravure printing, and indigo printing.

On the other hand, as shown in FIG. 8, it is understood that a plurality of character patterns 200 on which various characters, etc. are printed, are printed on the transfer paper 100 through the above-described printing method during the character pattern printing step (S100). I can.

The pressure-sensitive adhesive applying step (S200) is a step of forming the pressure-sensitive adhesive layer 250 by applying a pressure-sensitive adhesive on the character pattern portion 200 printed in the character pattern printing step (S100).

In the step of applying the pressure-sensitive adhesive (S200), a coating means for applying the pressure-sensitive adhesive to the surface of the transfer paper 100 on which the character pattern part 200 is printed may be performed. The coating means may include a coating roller unit having a coating roller, a cooling roller, or the like, or a screen printing unit performing a screen printing method.

In the step of interposing the PVC elastic foam (S300), a pair of transfer papers 100 to which an adhesive is applied in the pressure-sensitive adhesive application step (S200) are provided, and the PVC elastic foam (300) between the pair of transfer papers (100) This is the step of intervening. The term "PVC elastic foam" used in the present invention refers to a foam having resilience as a PVC material, and is referred to as PVC casting, PVC casting foam, PVC casting fabric, PVC casting foam, and the like. In addition, the PVC elastic foam may be a cell formed by mixing a foaming agent using PVC as a raw material and generating gas under a constant temperature and pressure time.

As shown in FIG. 2, in the step of interposing the PVC elastic foam (S300), the transfer paper coated with the adhesive is arranged vertically apart so that the above-described character patterns 200 face each other, and the thickness is 0.5 mm ~ 6 A pair of PVC elastic foams 300 in cm may be interposed.

In this way, the PVC elastic foam 300 having a thickness in the above-described range is important in giving a three-dimensional texture to a user. If the thickness is less than 0.5 mm, the effect of imparting a three-dimensional texture is insignificant, and if the thickness exceeds 6 cm, the character pad is not easily detached during the character elastic pad manufacturing step (S500), which will be described later, and the product is less complete.

The character pattern part transfer step (S400) includes the transfer paper 100, the character pattern part 200, the adhesive layer 250, PVC elastic foam (300) sequentially arranged in the PVC elastic foam interposition step (S300). , Chlorine dioxide emission material 450, PVC elastic foam 300, adhesive layer 250, character pattern portion 200 and transfer paper 100 using a thermal compression means on the transfer paper 100 by thermocompression This is a step of transferring the character pattern part 200 onto the PVC elastic foam 300.

Referring to FIG. 2, in the character pattern transfer step (S400), the character pattern part 200 is transferred by thermal compression under a pressure (F) of 0.2 MPa or more and a temperature of 40 to 150° C. Foam 300 can be obtained. Such pressure and temperature are good for achieving the object of the present invention described above.

The chlorine dioxide-releasing material disposing step (S450) is a step of disposing a chlorine dioxide-releasing material 450 that releases a certain amount of gaseous chlorine dioxide between the pair of PVC elastic foams 300.

As shown in FIG. 4, the chlorine dioxide-releasing material 450 may be a chlorine dioxide solution tablet 451, a chlorine dioxide solution powder 452, or a chlorine dioxide solution pack 453.

The chlorine dioxide solution tablet 451, the chlorine dioxide solution powder 452, and the chlorine dioxide solution pack 453 may be manufactured using aqueous chlorine dioxide independently of each other.

Specifically, the chlorine dioxide water is obtained by dissolving chlorine dioxide in purified water.

For example, the chlorine dioxide water pack 453 may be manufactured by injecting the chlorine dioxide water onto the surface of the pack made of a soft plastic material (for example, urethane) with a hollow inside using an injector such as a syringe.

In addition, the chlorine dioxide water tablet 451 is formed by mixing a gel mixture obtained by mixing 1000 to 5000 parts by weight of purified water and 1000 to 5000 parts by weight of a superabsorbent polymer with respect to 100 parts by weight of the chlorine dioxide water, The aqueous chlorine dioxide powder 452 may be obtained by mixing the gel mixture with a mixed powder. Here, the mixed powder may include powder such as an activator, a drying agent, an adhesive, a release agent, and a foaming agent.

As shown in Figure 3, the character elastic pad manufacturing step (S500) is a high-frequency mold 10, the PVC elastic foam 300 on which the chlorine dioxide-releasing material 450 is disposed in the chlorine dioxide-releasing material disposing step (S450). ) By applying a high frequency and pressing one side (upper or lower) of the PVC elastic foam 300 to produce a character elastic pad 500 having a three-dimensional shape corresponding to the character pattern 200 .

As another example, as shown in FIG. 4, the character elastic pad manufacturing step (S500) comprises a PVC elastic foam 300 in which the chlorine dioxide emitting material 450 is disposed in the chlorine dioxide emitting material disposing step (S450). Character elastic pad 500 in which a three-dimensional shape corresponding to the character pattern 200 is molded by applying a high frequency using a pair of high frequency molds 10 and pressing both sides (or upper and lower surfaces) of the PVC elastic foam 300 ) Is a step of manufacturing.

In detail, referring to FIG. 6, at the time of manufacturing the character elastic pad (S500 ), the high frequency mold 10 has a protrusion 11 having a three-dimensional shape corresponding to the character pattern 200, and has the protrusion part. (11) A pair of high-frequency molds 10 having a key hook protrusion 12 forming a hook portion to which the key ring is coupled to one end are disposed.

In more detail, in the character elastic pad manufacturing step (S500), after placing a pair of high-frequency molds 10 on the PVC elastic foam 300, by applying a high frequency to the pair of high-frequency molds 10 Character elastic pad 500 in which a three-dimensional shape corresponding to the character pattern 200 is formed by rapidly heating to about 100 to 150° C. and pressing on the PVC elastic foam 300 while descending the high frequency mold 10 Can be manufactured.

In the character elastic pad manufacturing step (S500), when the high frequency mold 10 is used, the rim of the protrusion 11 protrudes the highest, so that the rim of the character pattern 200 is most severely fused. In this way, when the fused portion is formed along the edge of the character pattern portion 200, it can be easily detached along the fused portion.

At this time, as shown in Figure 7, the character elastic pad 500 according to the present invention is integrally bonded by fusion bonding the upper and lower edges of the PVC elastic foam 300 by high-frequency fusion using the high-frequency mold 10 , Characterized in that the central portion of the elastic pad 500 has a hollow structure and is formed by embedding the above-described chlorine dioxide emitting material 450 in the hollow structure.

On the other hand, as shown in Figure 6, the pair of high-frequency mold 10 is made of an upper plate (shown as (a) in Figure 6) and a lower plate (shown as (b) in Figure 6), the above In addition to the one key ring protrusion 12, it may further include a corrugated portion 13. The corrugated portion 13 is formed on one surface of the high-frequency mold 10, and is formed at a relatively lower height than the protruding portion 11. Accordingly, since heat energy due to high frequency is intensively generated in the wrinkle portion 13, it is possible to further impart a three-dimensional effect to the surface of the character elastic pad 500 to be finally manufactured.

Furthermore, the present invention minimizes the defect rate and improves the efficiency of work by including a failure determination unit 20 that detects a voltage difference applied to the upper and lower plates of the high frequency mold 10 during the character elastic pad manufacturing step (S500). You can increase it.

The failure determination unit 20 measures the voltage V1 applied to the upper plate and the voltage V2 applied to the lower plate of the high-frequency mold 10, but if the following Equation 1 is not satisfied, it may be determined as a failure or failure. As a specific and non-limiting example, when the voltage applied to the high frequency mold 10 is different, the position of the protrusions 11 formed on the upper and lower plates of the high frequency mold 10 may be shifted, resulting in loss, or It may be a defect due to abrasion of the protrusion 11 due to frequent use.

[Equation 1]

((V1-V2)/V2)×100 ≤ 10

In addition, as shown in FIGS. 9 to 11, various characters, etc. are printed through the character elastic pad manufacturing step (S500) according to an embodiment of the present invention, but the character elastic pad 500 manufactured by molding in an embossing shape is It can be seen that it is manufactured.

In addition, as shown in Figs. 12 and 13, after the character elastic pad manufacturing step (S500), a key ring is coupled to a hook formed on the character elastic pad 500, and a character elastic pad set with a key ring ( 501, 502) can be completed.

14 is a result of measuring the amount of chlorine dioxide released in the gas phase to the character elastic pad 500 for a key ring having virus blocking ability according to an embodiment of the present invention.

The method of measuring the amount of chlorine dioxide emission was measured using a chlorine dioxide meter (model: GASTIGER 2000) in a measuring room maintained at a room temperature of 23 to 26 °C and a relative humidity of 23 to 24 %.

As shown in FIG. 14, since the character elastic pad 500 manufactured as described above includes the chlorine dioxide emitting material 450, it can be seen that the gaseous chlorine dioxide emission amount is 0.02 to 0.03 ppm. The amount of gaseous chlorine dioxide released is an amount capable of sufficiently expressing the virus blocking function. In addition, it was confirmed that the virus blocking sticker 200 maintains a gaseous chlorine dioxide emission of 0.02 to 0.03 ppm for at least 30 days at room temperature.

As described above, the method of manufacturing a character elastic pad for a key ring having a virus blocking ability according to the present invention includes a character pattern printing step (S100), an adhesive application step (S200), a PVC elastic foam interposition step (S300), and a character pattern part By including the transfer step (S400), the chlorine dioxide emitting material arrangement step (S450) and the character elastic pad manufacturing step (S500), the above-described character pattern portion 200 is printed and molded to have an embossed shape, and a detachable form It is manufactured with.

On the other hand, the method for manufacturing a character elastic pad for a key ring having a virus blocking ability according to another embodiment of the present invention is to remove the above-described transfer paper 100 before the character elastic pad manufacturing step (S500), and then remove the PVC transparent film. It may include; a PVC transparent film disposing step (S470) to be disposed on the PVC elastic foam.

As shown in FIG. 15, after the chlorine dioxide-releasing material disposing step (S450), the PVC transparent film disposing step (S470) is performed, and then the character elastic pad manufacturing step 500 is performed. After performing step (S470) and performing the character elastic pad manufacturing step 500, it is possible to form a certain texture and touch on the surface of the character elastic pad 500.

In addition, unlike FIG. 15, the present invention may perform the chlorine dioxide-releasing material disposition step (S450) after the PVC transparent film disposition step (S470), and then perform the character elastic pad manufacturing step 500. .

In addition, the PVC transparent film disposing step (S470) may solve the problem that occurs during the character elastic pad manufacturing step (S500). That is, the above-described character pattern portion 200 is attached to the inside of the lower plate protrusion 11 of the high-frequency mold 10 due to high pressure and high heat, thereby damaging the printed matter. However, as the PVC transparent film arranging step (S470) is included, the PVC transparent film is easily fused or deformed by heat, pressure, and high frequency during the character elastic pad manufacturing step (S500) unlike other materials. Therefore, the above problems can be solved.
