Description

탄소나노튜브 안경렌즈 및 제조방법Carbon Nanotube Glasses Lens and Manufacturing Method
본 발명은 탄소나노튜브 안경렌즈에 관한 것으로, 안경렌즈의 원료로서 탄소나노튜브를 포함하며, 또한 안경렌즈 표면을 탄소나노튜브코팅처리하는 탄소나노튜브 안경렌즈에 관한 것이다.The present invention relates to a carbon nanotube spectacle lens, comprising a carbon nanotube as a raw material of the spectacle lens, and a carbon nanotube spectacle lens for carbon nanotube coating treatment on the surface of the spectacle lens.
또한, 본 발명은 탄소나노튜브 안경렌즈 제조방법에 관한 것으로, 안경렌즈의 원료로서 탄소나노튜브를 포함하며, 또한 안경렌즈 표면을 탄소나노튜브코팅처리하는 탄소나노튜브 안경렌즈 제조방법에 관한 것이다.The present invention also relates to a carbon nanotube spectacle lens manufacturing method, comprising a carbon nanotube as a raw material of the spectacle lens, and to a carbon nanotube spectacle lens manufacturing method for carbon nanotube coating treatment of the spectacle lens surface.
일반적으로, 안경렌즈는 투명 플라스틱 또는 유리로 된 기판의 외부 표면상에 렌즈의 강도와 경도 보강 및 반사율 저하를 위해 다수개의 코팅층을 형성한다. In general, spectacle lenses form a plurality of coating layers on the outer surface of a transparent plastic or glass substrate to enhance the strength and hardness of the lens and to reduce the reflectance.
렌즈의 내충격성은 외부 충격에 저항하는 특성으로서 렌즈의 파손을 방지하는 안전성면에서 중요한 성질이라 할 수 있는데, 안경렌즈의 표면강도와 경도를 보강하여 내충격성의 향상을 제공한다. The impact resistance of the lens is an important property in terms of safety to prevent breakage of the lens as a property to resist external impact, and provides an improvement in impact resistance by reinforcing the surface strength and hardness of the spectacle lens.
플라스틱 렌즈는 경량이면서도 내 충격성이 우수할 뿐만 아니라, 유리렌즈에 비하여 염색이 용이하기 때문에 오늘날 각종 안경렌즈의 생산에 사용되고 있다. Plastic lenses are used in the production of various spectacle lenses today because they are lightweight and have excellent impact resistance, and are easy to dye as compared to glass lenses.
플라스틱 렌즈는 가볍고 렌즈의 충격 강도가 크지만 긁히기가 쉬우며, 색수차가 높으며(저ABBE값), 유리 전이 온도(Tg)가 낮음으로 인해서, 고온에서의 처리 조건에서 변형될 수 있는 단점이 있다.Plastic lenses have the disadvantage that they can be deformed under high temperature processing conditions due to their light weight, high impact strength but easy to scratch, high chromatic aberration (low ABBE value) and low glass transition temperature (Tg). .
공개특허공보 공개번호 10-2011-0113354호에는 종래기술로서 기재되어 있길, 현재 사용되는 플라스틱 안경렌즈는 굴절율에 따라서 저굴절율 렌즈, 중굴절율 렌즈, 고굴절율 렌즈, 초고굴절율 렌즈 등으로 구분된다. 저굴절율 렌즈는 굴절율(refractive index: nd)이 1.49이고, 중굴절율 렌즈는 nd1.56이고, 고굴절율 렌즈는 nd 1.60이고, 초고굴절율 렌즈는 nd 1.64~1.74이다.Patent Publication No. 10-2011-0113354 describes as a prior art, currently used plastic spectacle lenses are classified into a low refractive index lens, a medium refractive index lens, a high refractive index lens, an ultra high refractive index lens and the like according to the refractive index. The low refractive index lens has a refractive index of nd 1.49, the medium refractive index lens has a nd1.56, the high refractive index lens has a nd 1.60, and the ultra high refractive index lens has a nd 1.64 to 1.74.
저굴절율 안경렌즈는 디에틸렌 글리콜 비스알릴 카보네이트계(“CR-39”)수지가 주로 사용되고, 중굴절율 안경렌즈는 디알릴 프탈레이트계 수지가 사용되며, 고굴절율 안경렌즈는 브롬화 에폭시 아크릴레이트계 및 티오우레탄계 수지가 사용되고, 초고굴절율 안경렌즈에는 티오우레탄계 및 에피설피드계 수지가 주로 사용되고 있다.The low refractive index eyeglass lens is mainly made of diethylene glycol bisallyl carbonate resin (“CR-39”) resin, the medium refractive index eyeglass lens is made of diallyl phthalate resin, and the high refractive index eyeglass lens is made of brominated epoxy acrylate and thio Urethane-based resins are used, and thiourethane-based and episulfide-based resins are mainly used for ultra high refractive index eyeglass lenses.
본 발명은 중굴절율 안경렌즈에 사용되는 디알릴 프탈레이트계 수지에 관한 것으로 이 수지로 만든 렌즈의 내충격성을 향상시키기는 방법을 제공하기 위한 것이다. 렌즈의 특성 가운데 내충격성은 외부 충격에 파손되지 않고 저항하는 특성으로서 안경착용자의 안전성 측면에서 매우 중요한 특성이라 할 수 있다. 그러나 본 발명과 관련된 디알릴 프탈레이트 안경렌즈는 화학구조적으로 내충격성이 다른 플라스틱 안경렌즈보다 약하다는 결점이 있다.The present invention relates to a diallyl phthalate resin used in a medium refractive index spectacle lens and to provide a method for improving the impact resistance of a lens made of the resin. Impact resistance among the characteristics of the lens is a characteristic that is resistant to external shocks without being damaged, which is very important in terms of safety of eyewear wearers. However, the diallyl phthalate spectacle lens according to the present invention has a drawback that chemically impact resistance is weaker than that of other plastic spectacle lenses.
디알릴 프탈레이트계 수지 조성물을 이용한 플라스틱 광학재료용 단량체 조성물이 일본 특허공개 제2005-15670호에 개시되어 있다. 이 특허출원에서는 디알릴 화합물을 주성분으로 하는 중합성분 100 중량부에 대하여 이소프로필-n-프로필 퍼옥시 디카보네이트를 필수성분으로 하는 디알킬 퍼옥시 디카보네이트계 라디칼 중합개시제 성분 0.01 내지 10 중량부를 포함하는 플라스틱 광학재료용 단량체 조성물을 개시한다. 그러나 이 수지 조성물도 양호한 충격강도를 나타내는 데에는 한계가 있는 것으로 드러난다.A monomer composition for plastic optical materials using a diallyl phthalate resin composition is disclosed in Japanese Patent Laid-Open No. 2005-15670. This patent application contains 0.01 to 10 parts by weight of a dialkyl peroxy dicarbonate-based radical polymerization initiator component having isopropyl-n-propyl peroxy dicarbonate as an essential component with respect to 100 parts by weight of a polymer containing a diallyl compound as a main component. A monomer composition for plastic optical materials is disclosed. However, this resin composition also turns out to have a limit in showing good impact strength.
또한 중굴절율을 갖는 디알릴 프탈레이트계 수지 조성물에 대한 종래의 문제점은 디알릴 프탈레이트 모노머에 다가알콜을 에스테르 교환시켜 합성한 올리고머로 렌즈를 성형하여도 강도개선 효과가 매우 미미하다는 점이다.In addition, a conventional problem with the diallyl phthalate-based resin composition having a medium refractive index is that even when the lens is molded with an oligomer synthesized by transesterifying polyhydric alcohol to the diallyl phthalate monomer, the strength improvement effect is very insignificant.
특히 다가알콜의 몰비를 높여주면 강도개선 효과는 어느 정도 있지만 올리고머 용액점도가 급격히 상승하게 되어 몰드주입시 어려움이 있고 열경화 후에 이형성이 악화되는 경향이 있다.In particular, if the molar ratio of the polyhydric alcohol is increased, the effect of improving the strength to some extent, but the oligomer solution viscosity is sharply increased, there is a difficulty in mold injection and the releasability tends to worsen after heat curing.
따라서 상기 디알릴 테레프탈레이트 올리고머(A), 디알릴 이소프탈레이트 올리고머(B), 또는 상기 (A)와 (B)로 이루어지는 올리고머(이하 ‘기초수지’) 100 중량부에 대하여, 디알릴 오르소프탈레이트 올리고머(C) 10~40 중량부, 및 디부틸푸말레이트(D) 3~10 중량부를 포함하는 것을 특징으로 하는 내충격성 플라스틱 안경렌즈 수지조성물이 공개되어 있다.Therefore, diallyl orthophthalate based on 100 parts by weight of the diallyl terephthalate oligomer (A), diallyl isophthalate oligomer (B), or an oligomer (hereinafter, 'base resin') consisting of (A) and (B). An impact resistant plastic spectacle lens resin composition comprising 10 to 40 parts by weight of an oligomer (C) and 3 to 10 parts by weight of dibutyl fumarate (D) is disclosed.
등록특허공보 등록번호 10-0506300호에 종래기술로 공개되어 있는 바와 같이, 수년 동안 안경 렌즈의 제조에 플라스틱 소재가 사용되어 왔다. 플라스틱은 유리에 비해서 착용자에게 많은 이점을 주는데, 특히 이의 밀도가 낮아서 렌즈가 더 가볍고 렌즈의 충격 강도가 크다. 반대로, 플라스틱 렌즈는 긁히기가 쉬우며, 색수차가 높으며(저ABBE값), 유리 전이 온도(Tg)가 낮음으로 인해서, 고온에서의 처리 조건에서 변형될 수 있으며, 이로 인해서 렌즈가 “왜곡”되거나 또는 광학 왜곡의 정도가 크게 된다. 또한 플라스틱 렌즈는 일반적으로 유리에 비해서 굴절률이 낮기 때문에, 렌즈의 두께가 증가되며 미적인 어필이 감소하게 되는 경향이 있다. 디에틸렌 글리콜 비스(알릴 카보네이트)로 제조된 표준 “CR-39”형 렌즈는 굴절률이 1.498 이다.As disclosed in the prior art in Korean Patent Publication No. 10-0506300, plastic materials have been used for the manufacture of spectacle lenses for many years. Plastic offers many advantages for the wearer over glass, especially its low density, making the lens lighter and the impact strength of the lens larger. In contrast, plastic lenses are easy to scratch, have high chromatic aberrations (low ABBE values) and low glass transition temperatures (Tg), which can be deformed under high temperature processing conditions, causing the lens to “distort” or Or the degree of optical distortion becomes large. Plastic lenses also generally have a lower refractive index than glass, which increases the thickness of the lens and tends to reduce aesthetic appeal. Standard “CR-39” type lenses made of diethylene glycol bis (allyl carbonate) have a refractive index of 1.498.
기술의 진보로 인해 플라스틱 렌즈 성능에서의 개선이 가능하게 되었다. 코팅으로 인해서 긁힘 방지가 개선되었다. Advances in technology have enabled improvements in plastic lens performance. The coating improved scratch resistance.
일부의 플라스틱은 ABBE값이 비교적 높아서 색수차의 효과를 최소로 하는데 적절하다.Some plastics have relatively high ABBE values and are suitable for minimizing the effects of chromatic aberration.
기계 및 광학 렌즈 처리 장치 및 방법에서의 진보로 인해서 유리 전이 온도가 낮은 소재를 사용할 수 있게 되었다. 굴절률이 높은 플라스틱 및 물리적인 렌즈 디자인 개선은 플라스틱 렌즈의 미적인 어필을 개선시키는데 일조하였다.Advances in mechanical and optical lens processing apparatus and methods have allowed the use of materials with low glass transition temperatures. High refractive index plastic and physical lens design improvements have helped to improve the aesthetic appeal of plastic lenses.
이러한 개선점은 플라스틱 렌즈 시장에 있어서 수용되고 있고, 플라스틱 렌즈가 미국에서 대다수의 안경류를 구성하고 있어서, 우수한 안경 렌즈는 하기와 같은 특성을 갖는 성능에 대한 기대를 증대시키고 있다.These improvements have been accepted in the plastic lens market, and since plastic lenses make up the majority of eyewear in the United States, excellent eyeglass lenses are increasing expectations for performance having the following characteristics.
그리고 프탈산 무수물을 사용하여 제조된 수지는 통상적으로 “오르토 수지”로 칭하며; 이소프탈산으로 제조된 것은 “이소 수지”로 칭한다. And resins prepared using phthalic anhydride are commonly referred to as "ortho resins"; What is made of isophthalic acid is called "iso resin".
안경 렌즈를 제조하는데 바람직한 특성에 대해서는 긁힘 방지가 우수한 통상의 이소 수지는 일반적으로 착색속도가 느리다. 반대로, 통상의 오르토 수지는 통상적으로 긁히기 쉽지만, 착색속도는 빠르다. 모든 불포화 폴리에스테르수지는 다소 불균일하게 중합되어 내부 광학 왜곡 또는 가시 “파”를 야기한다.As for the desirable properties for producing spectacle lenses, conventional iso resins having excellent scratch resistance generally have a slow coloring speed. In contrast, conventional ortho resins are usually easy to scratch, but have a high coloration rate. All unsaturated polyester resins polymerize somewhat unevenly, causing internal optical distortion or visible “waves”.
전술한 바와 같이, 스티렌은 불포화 폴리에스테르 조성물과의 가교 희석제 단량체로서 흔히 사용된다. 스티렌의 비율이 증가할수록, 굴절률 또한 증가한다. 그러나, 고 농도의 스티렌을 사용하는 것은 렌즈 내에서의 광학 왜곡을 형성하도록 야기하는 중합 조성물 내에서 반응의 발열이 크게 되어 렌즈의 광학 왜곡을 형성하게된다. 광학 균일도를 개선시키고(광학왜곡을 감소시킴), 불포화 폴리에스테르 수지계 안경 렌즈 조성물에서의 착색 속도를 증가시키면서, 고 굴절률 및 색상을 유지하는 것은 쉬운 일이 아니다.As mentioned above, styrene is commonly used as crosslinker diluent monomer with unsaturated polyester compositions. As the proportion of styrene increases, the refractive index also increases. However, the use of high concentrations of styrene results in large heat generation of the reaction in the polymerizing composition that causes the optical distortion to form in the lens, resulting in optical distortion of the lens. It is not easy to maintain high refractive index and color while improving optical uniformity (reducing optical distortion) and increasing the coloration speed in unsaturated polyester resin based spectacle lens compositions.

On the outer surface of the lens, a water repellent coating layer having a water film preventing effect is formed. The conventional spectacle lens of this structure is a plastic substrate whose main material is a non-conductive material, so if the surface of the lens is wiped with gauze or rubbed on clothes, hair, etc., static electricity is generated on the lens and foreign matter such as dust in the air is easily attached. There is a problem that needs to be cleaned frequently and dirty. In addition, the spectacle lens accumulates fatigue in the eyes of a user due to reflection of light and deterioration of blood circulation when worn for a long time, and causes a disease in the eyes when contaminated with bacteria.
