터치패널용 강화유리 제조방법 { Manufacturing method of strengthed glass for touch panel }Manufacturing Method of Strengthed Glass for Touch Panel

본 발명은 강화유리 제조방법에 관한 것으로서, 특히 휴대폰, PDA, 내비게이션, 랩북 등 터치패널을 갖는 전자기기에 장착되는 강화유리를 제조함에 있어서, 기존의 방법 대신 마스킹 잉크를 사용하여 강화유리에 스크래치 등이 발생되지 않도록 강화유리를 제조하여 공정 단축 및 원가 경쟁력이 탁월한 터치패널용 강화유리 제조방법에 관한 것이다.The present invention relates to a method for manufacturing tempered glass, and in particular, in manufacturing tempered glass mounted on an electronic device having a touch panel such as a mobile phone, a PDA, a navigation system, a labbook, and the like, using a masking ink instead of a conventional method, scratching on tempered glass, etc. The present invention relates to a method for manufacturing tempered glass for a touch panel having excellent tempered glass and cost competitiveness by preventing tempered glass from occurring.

일반적으로 핸드폰 등에 장착되어 있는 표시창은 가격이 저렴하고 제작이 용이한 합성수지 재질인 아크릴수지가 사용되고 있다.In general, an acrylic resin, which is a synthetic resin material, is used for a display window mounted on a mobile phone, which is inexpensive and easy to manufacture.

하지만 최근에 핸드폰 등의 표시창에 터치패널이 장착되면서 기존의 아크릴 수지를 다음과 같은 이유로 사용할 수 없게 되었다. However, recently, as the touch panel is mounted on the display window of the mobile phone, the existing acrylic resin cannot be used for the following reasons.

(1) 열과 스크래치에 취약, (2) 표시창의 투과율이 유리보다 나쁘다 (3) 선명한 화면을 위해 휘도를 높여야 하나 상대적으로 배터리 소모가 많다. (1) It is vulnerable to heat and scratches, (2) The transmittance of display window is worse than glass. (3) The brightness needs to be increased for clear screen, but it consumes a lot of battery.

그래서 위의 문제점이 없는 강화유리가 모든 터치패널에 사용되고 있다. Therefore, tempered glass without the above problems is used in all touch panels.

현재 강화유리 가공 방식은 제조공정이 길고 수가공이 많아 생산성 및 경제 성 문제가 있다. Currently tempered glass processing method has a long manufacturing process and a lot of handwork, there are productivity and economic problems.

도 1은 종래의 터치 판넬 및 휴대단말기 강화유리 제조방법의 공정순서도이다.1 is a process flowchart of a method for manufacturing a conventional touch panel and a portable terminal tempered glass.

도 1에 도시 된 바와 같이 강화 유리 제조공정은, 원판 글라스가 입고되면 원판에 스크래치나 각종 이물질이 없는지를 검사(S1)하고, 원판 글라스를 카세트에 적재한 상태에 원판을 절단하여 글라스윈도우의 외형을 갖게 하되 외각(外殼)0.5mm - 2mm의 여유를 갖도록 절단 및 분할(S2)해 내고, 원판 글라스의 절단에 의해 분할된 글라스윈도우측에 남겨진 0.5mm - 2mm의 외각을 그라인딩 연마기를 사용하여 연마 처리함으로써 제거(S3)하고, 외각 연마가 완료된 글라스윈도우에 키버튼이나 카메라렌즈의 장착에 사용할 홀을 가공(S4)하며, 연마 처리된 글라스윈도우의 외곽면을 면취 가공 및 홀 내면을 연마하여 외형을 가공(S5)하는 단계를 포함하여 이루어진다.As shown in FIG. 1, the tempered glass manufacturing process, when the original glass is received, the original glass is inspected for scratches or other foreign matters (S1), and the original glass is cut in a state where the original glass is loaded in the cassette to cut the appearance of the glass window. Cutting and dividing (S2) to make a clearance of 0.5mm-2mm, and grinding the grinding edge of 0.5mm-2mm left on the side of the glass window divided by the cutting of the original glass using a grinding machine. Process to remove (S3), and process the hole to be used for mounting the key button or the camera lens in the glass window of the external polishing is completed (S4), and the outer surface of the polished glass window by chamfering and polishing the inner surface of the hole It comprises a step of processing (S5).

그리고, 외형 가공이 완료된 글라스윈도우의 양면을 표면연마(S6)하고 수세단계(S7) 및 열처리에 의한 강화단계(S8) 등 후공정을 수행하면 글라스윈도우의 제조 및 생산을 완료하게 된다.Then, the surface of the glass window is finished, both surface polishing (S6) and performing the post-process, such as washing step (S7) and the strengthening step (S8) by heat treatment to complete the manufacture and production of the glass window.

그런데, 기존의 제조기술에 의한 터치패널 및 휴대단말기용 글라스윈도우 가공방식은 원판을 먼저 절단하여 글라스윈도우를 분할해내고 외각을 연마하여 제거하므로 재료 누수가 많고 제조공정이 길어진다.However, the glass window processing method for the touch panel and the portable terminal according to the existing manufacturing technology cuts the original plate first, divides the glass window, and polishes and removes the outer shell, thus increasing material leakage and lengthening the manufacturing process.

또한, 유리에 보호막 없이 제조를 하기 때문에, 유리 표면에 발생한 불량(스크래치, 이물질, 지문 등)을 제거하기 위해 별도의 표면 연마 공정을 수행함으로 공정 수가 증가하고 이 연마 공정은 전부 수가공을 통해 이루어짐으로 작업성 및 생산성이 저하되는 문제점이 있다.In addition, since the glass is manufactured without a protective film, the number of processes is increased by performing a separate surface polishing process to remove defects (scratches, foreign substances, fingerprints, etc.) generated on the glass surface, and all the polishing processes are made by hand. As a result, workability and productivity are deteriorated.

도 2는 본 발명의 실시예에 따른 강화유리 제조방법의 공정순서도이다.2 is a process flowchart of the tempered glass manufacturing method according to an embodiment of the present invention.

도 2에 도시된 바와 같이, 본 발명의 터치패널용 강화유리 제조방법은, 인쇄단계(S10)와, 건조단계(S20)와, 절단단계(S30)와, 가공단계(S40)와, 잉크제거단계(S50)와, 강화단계(S60)와, 세정단계(S70)와, 검사단계(S80)로 이루어진다.As shown in FIG. 2, the method for manufacturing a tempered glass for a touch panel of the present invention includes a printing step S10, a drying step S20, a cutting step S30, a processing step S40, and ink removal. It consists of a step S50, a reinforcement step S60, a cleaning step S70, and an inspection step S80.

상기 인쇄단계(S10)는, 입고된 원판유리의 양면에 마스킹 잉크를 인쇄하는 단계이다.The printing step (S10) is a step of printing the masking ink on both sides of the stock glass.

상기 마스킹 잉크는 에폭시 레진(Epoxy Resin), 안료, 첨가제, 솔밴트 등을 포함하여 이루어진다.The masking ink includes an epoxy resin, a pigment, an additive, a solvent, and the like.

상기 마스킹 잉크는 부피비로, 에폭시레진:80~90%, 안료, 첨가제, 솔밴트:10~20% 로 이루어진다.The masking ink is composed of epoxy resin: 80 to 90%, pigment, additive, and solvent: 10 to 20% by volume.

상기 에폭시 레진은 마스킹 잉크의 80% 이상을 차지하는 주성분으로써, 상기 원판유리에 마스킹 잉크가 도포된 후 상기 마스킹 잉크가 필름화되도록 하는 물질이다.The epoxy resin is a main component occupying 80% or more of the masking ink, and is a material that allows the masking ink to be filmed after the masking ink is applied to the disc glass.

상기 안료는 마스킹 잉크의 색깔을 좌우하는 물질이다.The pigment is a substance that influences the color of the masking ink.

상기 첨가제는 상기 에폭시레진을 액상화시키면서 마스킹 잉크의 여러 성분들이 제역할을 하도록 도와주는 물질이다.The additive is a material that helps various components of the masking ink to liquefy the liquefied epoxy resin.

상기 솔밴트는 마스킹 잉크가 원판유리에 도포될 때, 균일성 유지와 빠른 건조를 도와주는 역할을 한다.The solvent serves to help maintain uniformity and quick drying when the masking ink is applied to the disc glass.

상기 건조단계(S20)는 상기 마스킹 잉크가 인쇄된 원판유리를 건조하는 단계이다.The drying step (S20) is a step of drying the original glass on which the masking ink is printed.

상기 건조단계(S20)에서는 마스킹 잉크가 인쇄된 원판유리를 100 ~ 120℃ 정도에서 약 10가량 건조하여, 상기 마스킹 잉크가 필름화되어 상기 원판유리의 양면에 밀착되도록 한다.In the drying step (S20), the masking ink is printed on the original glass about 10 to about 10 ℃ at about 100 ~ 120 ℃, the masking ink is filmed to be in close contact with both sides of the original glass.

상기 절단단계(S30)는, 상기 건조단계(S20)에 의해 건조된 상기 원판유리를 일정한 크기의 단위유리로 절단하는 단계이다.The cutting step (S30) is a step of cutting the original glass dried by the drying step (S20) into a unit glass of a predetermined size.

이때, 상기 단위유리라 함은, 핸드폰, PDP, 랩북 등 터치패널을 갖는 전자기기에서 터치패널용으로 장착될 수 있도록 절단된 크기의 유리를 말한다.In this case, the unit glass refers to a glass of a cut size so that it can be mounted for a touch panel in an electronic device having a touch panel such as a mobile phone, a PDP, a labbook, and the like.

상기 절단단계(S30)에서는 상기 원판유리는 CNC Glass 절단기 또는 Laser Glass 절단기를 이용하여 단위유리로 절단한다.In the cutting step S30, the disc glass is cut into unit glass using a CNC glass cutter or a laser glass cutter.

상기 가공단계(S40)는, 절단된 상기 단위유리의 외곽을 연마하거나 홀 또는 홈을 형성하는 단계이다.The processing step (S40) is a step of grinding the outer portion of the cut unit glass or to form a hole or groove.

상기 가공단계(S40)에서 상기 단위유리의 외곽을 연마하거나 홀 또는 홈을 형성할 때, 상기 단위유리의 상하면에는 상기 마스킹 잉크가 필름화되어 접착되어 있기 때문에, 상기 단위유리에 스크래치가 발생하거나 이물질이 접착되지 않도록 할 수 있다.When the outer surface of the unit glass is polished or holes or grooves are formed in the processing step (S40), since the masking ink is filmed and adhered to the upper and lower surfaces of the unit glass, scratches are generated or foreign matters on the unit glass. This can be prevented from adhering.

상기 잉크제거단계(S50)는, 가공된 상기 단위유리에 인쇄된 상기 마스킹 잉크를 제거하는 단계이다.The ink removing step (S50) is a step of removing the masking ink printed on the processed unit glass.

상기 마스킹 잉크는 상기 건조단계(S20)에서 필름화되고, 필름화된 상기 마스킹 잉크는 상기 잉크제거단계(S50)에서 잉크제거용액에 의해 상기 단위유리로부터 박리되어 제거된다.The masking ink is filmed in the drying step S20, and the masking ink filmed is peeled off and removed from the unit glass by an ink removing solution in the ink removing step S50.

상기 잉크제거단계(S50)에서는 단위유리를 상기 잉크제거용액에 침지시키되, 상기 잉크제거용액은, KOH, 글루콘산 소다(Sodium Gluconate, NaC6H11O7), 증류수가 혼합되어 이루어진다.In the ink removal step (S50), the unit glass is immersed in the ink removal solution, the ink removal solution, KOH, sodium gluconate (Sodium Gluconate, NaC 6 H 11 O 7 ), distilled water is mixed.

상기 잉크제거용액은, 부피비로 KOH:3~8%, 글루콘산 소다:5~10%, 증류수:82~92% 로 이루어지고, 용액온도는 50~60℃이며, 침지시간은 5~15분이 되도록 한다.The ink removal solution, KOH: 3 ~ 8%, Sodium Gluconate: 5 ~ 10%, Distilled water: 82 ~ 92% by volume ratio, the solution temperature is 50 ~ 60 ℃, immersion time is 5 ~ 15 minutes Be sure to

상기 마스킹 잉크가 도포된 상기 단위유리를 상기 잉크제거용액에 넣을 경우, KOH의 K이온이 에폭시 레진의 카본체인을 짜르고, 이후 글로콘산 소다의 수많은 OH이온이 끈어진 카본들과 결합하여 최종적으로 필름화된 마스킹 잉크를 단위유리로부터 박리시키게 된다.When the unit glass coated with the masking ink is added to the ink removing solution, K ions of KOH squeeze the carbon chain of epoxy resin, and then combine with numerous OH ions of soda gluconate and finally the film. The masking ink is liquefied from the unit glass.

상기 강화단계(S60)는 상기 마스킹 잉크가 제거된 상기 단위유리를 강화하는 단계이다.The step of strengthening (S60) is a step of strengthening the unit glass from which the masking ink is removed.

상기 단위유리를 강화하는 방법으로는, 열처리 방식과 화학처리 방식이 있는데, 화학처리 방식을 사용함이 바람직하다.As a method of strengthening the unit glass, there are a heat treatment method and a chemical treatment method, and a chemical treatment method is preferably used.

화학처리 방식으로는, 질산칼륨 및 세라믹 안료용액이 함유된 강화용액에 상기 단위유리를 넣고 400~500℃의 온도로 4~6시간 침지시켜 단위유리를 강화시킨다.In the chemical treatment method, the unit glass is placed in a tempered solution containing potassium nitrate and a ceramic pigment solution and immersed at a temperature of 400 to 500 ° C. for 4 to 6 hours to strengthen the unit glass.

상기 강화단계(S60)에서 단위유리를 강화용액에 넣으면, 유리에 내재된 나트륨이온과 질산칼륨 용액의 칼륨이온이 이온교환이 이루어지는바, 유리표면에 분포하는 작은 이온(나트륨이온)은 빠져나오고 그 자리에 질산칼륨 용액 내의 큰 이온 (칼륨이온)이 들어가게 됨으로써, 유리 표면의 밀도가 높아져 표면압축이 이루어지게 된다.When the unit glass is put into the tempered solution in the step of strengthening (S60), the sodium ions and the potassium ions of the potassium nitrate solution in the glass are ion-exchanged, and small ions (sodium ions) distributed on the glass surface are released. As large ions (potassium ions) in the potassium nitrate solution enter the site, the density of the glass surface is increased and surface compression is achieved.

그리고, 상기 세라믹 안료용액은 단위유리를 강화시키면서 유리의 색상을 좋게 하는 역할을 한다.The ceramic pigment solution serves to enhance the color of the glass while strengthening the unit glass.

상기 세정단계(S70)에서는 강화된 상기 단위유리를 세정하는 단계로써, 초음파 세정을 통해 단위유리를 세정함이 바람직하다.In the cleaning step (S70) as a step of cleaning the strengthened unit glass, it is preferable to clean the unit glass through ultrasonic cleaning.

상기 검사단계(S80)는 세정된 상기 단위유리를 검사하는 단계이다.The inspection step (S80) is a step of inspecting the cleaned unit glass.

상기 단위유리는 검사 후 포장을 하여 출고를 하게 된다.The unit glass is packaged and shipped after inspection.

위와 같이 상기 원판유리를 절단하거나, 상기 단위유리를 가공함에 있어서, 유리의 상면과 하면에 각각 상기 마스킹 잉크가 도포되어 있기 때문에, 절단 또는 가공시 유리에 스크래치 등이 발생하지 않도록 하여, 유리의 불량률을 감소시킬 수 있다.In the cutting of the original glass or processing the unit glass as described above, the masking ink is applied to the upper and lower surfaces of the glass, respectively, so that no scratch or the like occurs in the glass during cutting or processing, so that the defective rate of the glass is reduced. Can be reduced.
