편광필름, 편광렌즈 및 이의 제조방법{A polarized film, a polarized lens and a method for producing the same}A polarized film, a polarized lens and a method for producing the same

본 발명은 편광렌즈에 관한 것으로, 더욱 상세하게는 편광렌즈의 최외곽에 부착되는 CR39의 접착력을 부여시키기 위한 편광필름, 편광렌즈 및 이의 제조방법에 관한 것이다.The present invention relates to a polarizing lens, and more particularly, to a polarizing film, a polarizing lens, and a manufacturing method for imparting the adhesive force of the CR39 attached to the outermost of the polarizing lens.

편광필름이란 입사광의 수직 또는 수평 편파를 구분하여 통과시키거나 차단시킬 수 있는 성질의 필름을 말한다. 액정디스플레이(LCD) 모듈의 백라이트에서 나오는 빛의 세기는 모든 방향으로 균등하나 편광렌즈는 광 중에서 편광 축과 동일한 방향의 광만 투과시키고 그 외는 흡수 또는 반사하여 특정 방향의 편광을 만드는 역할을 한다. The polarizing film refers to a film having a property of passing or blocking vertical or horizontal polarization of incident light. Although the intensity of light emitted from the backlight of the liquid crystal display (LCD) module is equal in all directions, the polarizing lens transmits only the light in the same direction as the polarization axis of the light, and absorbs or reflects the other light to make polarization in a specific direction.

상기 편광필름은 액정디스플레이(LCD)를 사용하는 손목시계, 전자수첩, 노트북, 컴퓨터, 캠코더 등의 화상 표시장치나 선글라스와 같이 편광을 요구하는 분야에서 광범위하게 이용되고 있다.The polarizing film has been widely used in fields requiring polarization, such as sunglasses, image display devices such as wristwatches, electronic notebooks, notebooks, computers, camcorders, and sunglasses using a liquid crystal display (LCD).

In this state, the CR39 units, which are optical lenses, are respectively cured in the casting process on the TAC film, thereby completing a polarized lens.

그러나 상기한 바와 같은 종래 기술에서는 다음과 같은 문제점이 있다.However, the above-described conventional techniques have the following problems.

상술한 과정에 의해 완성된 편광렌즈에서 CR39 단위체는 TAC 필름과 쉽게 분리되는 문제점이 있다. 이는 상기 CR39 단위체와 TAC 필름 사이의 접착력이 충분하지 않아서이다. 따라서, 제품을 사용하는 도중에 외부 충격 등에 의해 쉽게 분리되어 소비자의 제품에 대한 신뢰성을 떨어뜨리는 결과를 가져온다.CR39 unit in the polarization lens completed by the above process has a problem that is easily separated from the TAC film. This is because the adhesive force between the CR39 unit and the TAC film is not sufficient. Therefore, during the use of the product, it is easily separated by an external impact or the like, resulting in a decrease in the reliability of the product of the consumer.

따라서, 본 발명의 목적은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위한 것으로, TAC 필름과 CR39 단위체의 접착력을 향상시킬 수 있는 편광필름, 편광렌즈 및 이의 제조방법을 제공하는 것이다.Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a polarizing film, a polarizing lens, and a method for manufacturing the same, which can improve the adhesion between the TAC film and the CR39 unit.

이하 본 발명에 의한 편광필름, 편광렌즈 및 이의 제조방법의 바람직한 실시예를 첨부된 도면을 참고하여 상세하게 설명한다.Hereinafter, a preferred embodiment of a polarizing film, a polarizing lens, and a manufacturing method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 의한 편광렌즈의 제조과정을 보인 구성도이고, 도 2는 본 발명에 의한 편광렌즈의 바람직한 실시예의 구성을 보인 구성도이다.1 is a block diagram showing a manufacturing process of a polarizing lens according to the present invention, Figure 2 is a block diagram showing a configuration of a preferred embodiment of a polarizing lens according to the present invention.

이들 도면에 도시된 바에 따라 편광렌즈가 제조되는 과정을 중심으로 설명하 면, 편광렌즈를 제조하는 형틀로서의 역할을 수행하는 가스켓(10)이 구비된다. 그리고, 상기 가스켓(10)의 상하부에는 각각 가스켓(10)과 함께 형틀로서의 역할을 수행하는 몰드체(12)가 각각 구비된다. 그리고, 상기 몰드체(12)의 사이에 합지된 폴리비닐알코올 필름(20)과 TAC 필름이 위치하도록 한다.Referring to the process of manufacturing a polarizing lens as shown in these drawings, the gasket 10 is provided as a template for manufacturing a polarizing lens. In addition, upper and lower portions of the gasket 10 are respectively provided with a mold body 12 which serves as a mold together with the gasket 10. In addition, the polyvinyl alcohol film 20 and the TAC film laminated between the mold bodies 12 are positioned.

상기 폴리비닐알코올 필름(20)의 제조과정을 간단하게 설명하면, 폴리비닐알코올 롤 필름(도시되지 않음)을 요오드 용액 또는 염료로 염색하여 상기 필름 내로 요오드 이온을 확산시킨 후, 상기 폴리비닐알코올 롤 필름을 일축 방향으로 연신시켜 필름 형상의 폴리비닐알코올 필름(20)을 제조한다. 전술한 바와 같은 폴리비닐알코올 롤 필름의 연신 및 염착공정을 수행함으로써, 입사된 광이 편향하여 평행 방향의 광선은 흡수되고 수직 방향의 광선만 폴리비닐알코올 필름(20)을 통과하도록 하는 편광 효과가 나타난다. Briefly describing the manufacturing process of the polyvinyl alcohol film 20, after dyeing a polyvinyl alcohol roll film (not shown) with an iodine solution or a dye to diffuse iodine ions into the film, the polyvinyl alcohol roll The film is stretched in the uniaxial direction to produce a film-shaped polyvinyl alcohol film 20. By performing the stretching and dyeing process of the polyvinyl alcohol roll film as described above, the incident light is deflected so that light in the parallel direction is absorbed and only the light in the vertical direction passes through the polyvinyl alcohol film 20. Appears.

이러한 연신 공정에 의해 형성된 폴리비닐알코올 필름(20)의 양면에는 TAC 필름(22)이 부착되는데, 상기 TAC 필름(22)을 부착하기 전에 상기 TAC 필름(22)의 표면에는 코팅처리가 이루어진다(S10). 상기 코팅처리는 아래에서 설명될 CR39 단일체(30)가 상기 TAC 필름(22)에 보다 견고하게 부착되기 위해 하는 공정이다. 즉, 종래와 같이 상기 TAC 필름(22)의 표면에 별도의 공정없이 CR39 단일체(30)를 부착하여 CR39 단일체(30)가 쉽게 분리되는 것을 방지하기 위해 이와 같은 코팅처리를 하는 것이다. The TAC film 22 is attached to both surfaces of the polyvinyl alcohol film 20 formed by the stretching process, and the surface of the TAC film 22 is coated before attaching the TAC film 22 (S10). ). The coating is a process in which the CR39 monolith 30 to be described below is more firmly attached to the TAC film 22. That is, by attaching the CR39 unitary body 30 without a separate process on the surface of the TAC film 22 as in the prior art, such coating treatment is performed to prevent the CR39 unitary body 30 from being easily separated.

상기 코팅처리는 다음과 같은 물질들에 의해 이루어진다.The coating is performed by the following materials.

우선, 상기 TAC 필름(22)의 표면에 직접 코팅되는 물질인 바인더(Binder)로 는 실리카 졸(Silica sol.) 15 ~ 40%, 아크릴 모노머(Acrylic monomers) 20 ~ 50%, 실란 화합물(Organo-functional silane) 1 ~ 15%가 포함된다.First, the binder (Binder), which is a material directly coated on the surface of the TAC film 22, includes 15 to 40% of silica sol, 20 to 50% of acrylic monomers, and a silane compound (Organo-). functional silane) 1 to 15%.

그리고, 상기 바인더를 TAC 필름(22)에 코팅시키기 위한 용매(Solvent)로서 에탄올(Ethanol)이 5 ~ 10%, 이소프로필 알코올(Isopropyl alcohol) 15 ~ 20%, 이소부탄올(Isobutanol) 15 ~ 30%, 아세트산에틸(ethyl acetate) 5 ~ 15%가 포함된다. 상기 바인더 및 용매로 사용되는 물질의 함유량은 반드시 상술한 내용에 한정되는 것은 아니다. 결국, 상기 용매는 바인더를 녹여 상기 TAC 필름(22)의 표면에 코팅막(24)이 형성되도록 한다.In addition, as a solvent for coating the binder on the TAC film 22, 5-10% of ethanol, 15-20% of isopropyl alcohol, 15-30% of isobutanol , 5-15% ethyl acetate. The content of the substance used as the binder and the solvent is not necessarily limited to the above contents. As a result, the solvent melts the binder so that the coating film 24 is formed on the surface of the TAC film 22.

상기 코팅처리는 그라비아 코팅, 나이프 코팅 등 다양한 방식에 의해 이루어질 수 있는데, 본 실시예에서는 바람직하게 슬롯다이(Slot die) 방식에 의해 이루어진다. 상기 슬롯다이 방식은 슬롯을 따라 코팅액이 배출되도록 한 것으로서, 상기 TAC 필름(22)의 표면에 골고루 코팅막(24)이 형성되도록 하는 이점이 있는 방식이다.The coating treatment may be performed by various methods such as gravure coating, knife coating, etc. In the present embodiment, a slot die method is preferable. The slot die method is to allow the coating liquid to be discharged along the slot, which is an advantage in that the coating film 24 is evenly formed on the surface of the TAC film 22.

다음으로, 상기 폴리비닐알코올 필름(20)의 양면에는 TAC 필름(22)을 부착된다(S20). 즉, 상기 TAC 필름(22)에서 코팅이 되지 않은 면이 상기 폴리비닐알코올 필름(20)과 부착된다. 참고로, 상기 TAC 필름(Tri Acetyl Cellulose film)(22)은 티비, 모니터, 노트북, 휴대폰 등에 사용되는 LCD 부품인 편광판을 보호해주는 필름의 일종으로 뛰어난 광학적 특성을 지닌 디스플레이용 전자재료이다.Next, the TAC film 22 is attached to both sides of the polyvinyl alcohol film 20 (S20). That is, the uncoated side of the TAC film 22 is attached to the polyvinyl alcohol film 20. For reference, the TAC film (Tri Acetyl Cellulose film) 22 is a kind of film for protecting a polarizing plate, which is an LCD component used in TVs, monitors, notebooks, mobile phones, etc., and is an electronic material for display having excellent optical characteristics.

상기 TAC 필름(22)은 상기 폴리비닐알코올 필름(20)의 기능을 보호하고, 아울러, 연신된 폴리비닐알코올필름(102)이 재수축되는 현상을 방지할 수 있다. 또 한, 상기 폴리비닐알코올 필름(20)은 매우 얇은 재질이기 때문에 상대적으로 경화된 재질인 TAC 필름(22)이 부착됨으로써 상기 폴리비닐알코올 필름(20)을 보호하고 이후의 공정을 보다 쉽게 할 수 있도록 한다.The TAC film 22 may protect the function of the polyvinyl alcohol film 20, and may also prevent the stretched polyvinyl alcohol film 102 from being recontracted. In addition, since the polyvinyl alcohol film 20 is a very thin material, the TAC film 22, which is a relatively hardened material, is attached to protect the polyvinyl alcohol film 20 and to facilitate subsequent processes. Make sure

상기 TAC 필름(22)을 상기 폴리비닐알코올 필름(20)에 쉽게 부착하기 위해서는 상기 폴리비닐알코올 필름(20)에 부착하기 전에 이른바, 전처리 공정을 수행하여야 한다. 상기 전처리 공정은 알칼리 처리 단계, 수세 단계 및 건조 단계 등으로 이루어진다. 이상의 전처리 공정은 이미 공지된 기술이므로 구체적인 설명은 생략하기로 한다.In order to easily attach the TAC film 22 to the polyvinyl alcohol film 20, a so-called pretreatment process should be performed before attaching the TAC film 22 to the polyvinyl alcohol film 20. The pretreatment process consists of an alkali treatment step, a water washing step and a drying step. Since the pretreatment process is a known technique, a detailed description thereof will be omitted.

이와 같이, 상기 폴리비닐알코올 필름(20)의 양면에 TAC 필름(22)이 부착되어 합지된 상태가 도 1에 도시되어 있다. As such, a state in which the TAC film 22 is attached and laminated on both surfaces of the polyvinyl alcohol film 20 is illustrated in FIG. 1.

다음으로, 상기 가스켓(10)과 몰드체(12) 사이에 합지된 폴리비닐알코올 필름(20)과 TAC 필름(22)이 위치하도록 한다. 이 상태가 되면, 상기 몰드체(12)와 TAC 필름(22)의 사이에는 주입공간(26)이 형성된다. 상기 주입공간(26)은 상기 TAC 필름(22)의 상하부에 각각 형성된다. Next, the polyvinyl alcohol film 20 and the TAC film 22 laminated between the gasket 10 and the mold 12 are positioned. In this state, an injection space 26 is formed between the mold 12 and the TAC film 22. The injection spaces 26 are formed in upper and lower portions of the TAC film 22, respectively.

그리고, 상기 주입공간(26)에는 CR39 단일체(30)가 주입된다. 상기 CR39 단일체(30)는 플라스틱렌즈의 일종으로서 광학적으로 가장 안정되어 선명한 시야를 제공하는 렌즈이다. 상기 CR39 단일체(30)는 주물의 형태로 상기 주입공간(26)에 주입된 후에 경화되면 코팅막(24)이 형성된 상기 TAC 필름(22)의 표면에 견고하게 부착된다(S30). In addition, the CR39 unit 30 is injected into the injection space 26. The CR39 unitary body 30 is a type of plastic lens that is optically the most stable and provides a clear field of view. The CR39 monolith 30 is hardened after being injected into the injection space 26 in the form of a casting and is firmly attached to the surface of the TAC film 22 on which the coating film 24 is formed (S30).

이와 같이 완성된 편광렌즈의 형상이 도 2에 잘 도시되어 있다. 본 발명에 의한 편광렌즈에서 상기 CR39 단일체(30)는 TAC 필름(22)에 코팅막(24)을 통해 부착된다. 이와 같이 상기 CR39 단일체(30)가 경화되어 완전하게 부착되면 종래보다 뛰어난 접착성을 가지게 된다. 따라서, 외부의 충격에 의해 상기 CR39 단일체(30)가 상기 TAC 필름(22)으로부터 쉽게 분리되는 것이 방지될 수 있다.The shape of the polarized lens thus completed is well illustrated in FIG. 2. In the polarizing lens of the present invention, the CR39 unitary body 30 is attached to the TAC film 22 through the coating film 24. As such, when the CR39 monolith 30 is hardened and completely attached, the CR39 monolith 30 has superior adhesiveness than before. Therefore, the CR39 monolith 30 can be easily prevented from being separated from the TAC film 22 by an external impact.

본 발명의 권리범위는 위에서 설명된 실시예에 한정되지 않고 청구범위에 기재된 바에 의해 정의되며, 본 발명의 기술분야에서 통상의 지식을 가진 자가 청구범위에 기재된 권리범위 내에서 다양한 변형과 개작을 할 수 있다는 것은 자명하다.The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.

예를 들어, 본 실시예에서는 상기 TAC 필름(22)의 표면에 먼저 코팅막(24)을 형성하고 상기 TAC 필름(22)을 폴리비닐알코올 필름(20)의 양면에 부착시켰으나, 이와 반대로 상기 폴리비닐알코올 필름(20)의 양면에 TAC 필름(22)을 부착시킨 상태에서 코팅막(24)을 형성하는 공정도 가능할 것이다.For example, in the present embodiment, the coating film 24 is first formed on the surface of the TAC film 22 and the TAC film 22 is attached to both surfaces of the polyvinyl alcohol film 20.
