Description
본 발명은 수지안경 렌즈와 그 제조금형 세척용 세척제에 관한 것으로 좀더 상세하게는 수지를 주원료로 사용하는 안경 렌즈와 이를 성형하기 위해 사용하는 금형을 보다 효과적으로 세척하기 위한 세척제를 제공하는데 있다.The present invention relates to a resin eyeglass lens and a cleaning mold for cleaning the mold thereof, and more particularly, to provide a spectacle lens using a resin as a main raw material and a cleaning agent for more effectively cleaning a mold used for molding the same.
일반적으로 안경렌즈는 유리제와 합성수지를 주원료로 사용하는 수지안경렌즈가 대표적으로 사용되고 있다.In general, the spectacle lens is a resin eyeglass lens that is made of glass and synthetic resin as the main raw material.
이때 수지안경렌즈는 합성수지를 이용하여 금형으로 성형하는 것에 의해 제조되는 것으므로 금형에 붙은 각종 이물질 및 필연적으로 피착될 수 밖에 없는 원재료를 다음번의 성형을 위하여 반드시 세척공정을 거쳐야 한다.At this time, since the resin eyeglass lenses are manufactured by molding into a mold using synthetic resin, various foreign substances adhering to the mold and raw materials that are inevitably to be deposited must be washed for the next molding.
이러한 금형의 세척과 그에 의해 제조된 안경렌즈를 세척하기 위하여 세척제를 사용하고 있다.In order to clean the mold and to clean the spectacle lens manufactured by using the cleaning agent is used.
종래에는 이러한 금형의 세척과 안경렌즈의 세척을 위하여 염화메틸렌(Methylene chloride)과 같은 유기용제 또는 인화성 물질등으로 초음파진동에 금형에 묻어있는 수지를 녹이는 방법에 의하여 세척을 하여 왔다.Conventionally, in order to clean such a mold and to clean an eyeglass lens, an organic solvent such as methylene chloride (methylene chloride) or a flammable material has been washed by dissolving a resin attached to the mold in ultrasonic vibration.
그러나 수지를 녹여서 세정을 취한다고 하나 그 잔분이 남아 후처리가 반드시 필요하고 특히 염화메틸렌에는 염소용매가 함유되어 있고, 특히 염소성분의 강력한 휘발성으로 이를 사용하여 금형 및 안경렌즈를 세척할 때에 인체에 유해환경을 발생시키는 문제점이 있으며, 폐액의 처리를 위하여 별도의 비용이 필요한 단점은 물론이고 안경렌즈의 표면을 부식시키는 문제점이 발견되고 있다.However, the resin is melted and washed, but the remainder remains necessary for post-treatment. Especially, methylene chloride contains chlorine solvent. Especially, due to the strong volatility of chlorine, it is used to clean the mold and spectacle lens. There is a problem of generating a harmful environment, a disadvantage that requires a separate cost for the treatment of the waste liquid, as well as problems of corrosion of the surface of the spectacle lens has been found.
본 발명은 상기와 같은 유기용제를 사용함으로서 발생되는 가장 큰 문제점인 환경오염 및 작업자의 인체유해 문제를 근본적으로 배제하면서도 금형과 그 금형에 의하여 제조된 안경렌즈를 완벽하게 세척할 수 있도록 하는데 있다.The present invention is to completely clean the mold and the spectacle lens manufactured by the mold while fundamentally excluding the environmental pollution and human hazards that are the biggest problem caused by using the organic solvent as described above.
이러한 목적을 달성하기 위하여 본 발명에서는 종래와 같이 금형 및 안경렌즈에 붙어있는 수지를 녹이는 방법에 의하여 처리하는 것이 아니라 고비점 알콜을 사용하여 온도 40∼60℃에서 수지를 용해, 침투, 팽창시켜 알칼리와 함께 수지를 세분시키는 생분해에 의하여 금형이 세척될 수 있도록 하였다.In order to achieve this purpose, the present invention does not process by melting the resin attached to the mold and the spectacle lens as in the prior art, but dissolves, penetrates and expands the resin at a temperature of 40 to 60 ° C. using a high boiling alcohol to give alkali. The mold can be washed by biodegradation to subdivide the resin.
이러한 세척제는 알칼리약품과 고비점 알콜 및 계면활성제를 혼합하여 본 발명에 부합하는 세척제를 얻을 수 있었다.Such detergents were mixed with alkali chemicals, high boiling alcohols and surfactants to obtain detergents consistent with the present invention.
이러한 본 발명은 수용성이여서 환경오염의 문제를 발생시키지 않으면서도 금형 및 안경렌즈를 용이하게 세척할 수 있도록 하는데 있다.The present invention is to be able to easily wash the mold and the spectacle lens without being a problem of environmental pollution because it is water-soluble.
이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
가성가리(Potassium hydroxide; KOH), 가성소다(Sodium hydroxide; NaOH),메타규산소다(Sodium silicate, Pentahydratte; Na2O SiO2H2O), 액규산소다(Sodium silicate; NaO nSiO2H2O)와 같은 알칼리약품중 2개이상을 선택하여 5∼32wt%로 조성하고, 물 59.9∼35wt%, 폴리프로필렌 글리콜(Polypropylene glycol; nC3H8O2), 폴리에칠렌글리콜[Polyethylene glycol; HOCH2(CH2OCH2)nCH2OH], 헥실렌글리콜(Hexylene glycol; C6H14O2)과 같은 고비점 알콜중 2개이상을 선택하여 35∼3wt%로 조성하고, 계면활성제 0.1∼10wt%, 저비점 알콜인 에칠알콜(C2H5OH)과 메탄올(Methanol;CH3OH)을 각각 0.1∼10wt%를 충분히 교반하여 얻은 조성물이 본 발명을 제공한다.Potassium hydroxide (KOH), sodium hydroxide (NaOH), sodium metasilicate (Sodium silicate, Pentahydratte; Na 2 O SiO 2 H 2 O), sodium silicate (NaO nSiO 2 H 2 O) Select two or more of the alkali chemicals, such as 5 to 32wt%, 59.9 to 35wt% water, polypropylene glycol (polypropylene glycol; nC 3 H 8 O 2 ), polyethylene glycol [Polyethylene glycol; Two or more high boiling alcohols such as HOCH 2 (CH 2 OCH 2 ) nCH 2 OH] and hexylene glycol (C 6 H 14 O 2 ) are selected and formulated at 35 to 3 wt%, and the surfactant is 0.1. The composition obtained by sufficiently stirring 0.1-10 wt% of ˜10 wt% and low boiling alcohol ethanol (C 2 H 5 OH) and methanol (Methanol; CH 3 OH), respectively, provides the present invention.
이러한 본 발명에서 상기한 가성가리(Potassium hydroxide; KOH), 가성소다(Sodium hydroxide; NaOH), 메타규산소다(Sodium silicate, Pentahydratte; Na2O SiO2H2O), 액규산소다(Sodium silicate; NaO nSiO2H2O)와 같은 알칼리약품에서 선택한 2개이상의 약품조성비를 5wt%이하로 조성되는 경우에는 금형을 세척하는 세척력이 크게 떨어지는 단점이 있는 반면에 그 조성비가 32wt%이상인 경우에도 세척력이 떨어질뿐만 아니라 수지안경렌즈를 성형하는 금형은 유리재질인 관계로 금형에 홈을 형성하거나 국소적으로 클렉이 발생하는 생기는 문제점이 있다.In the present invention, the caustic (Potassium hydroxide; KOH), sodium hydroxide (Sodium hydroxide; NaOH), sodium metasilicate (Sodium silicate, Pentahydratte; Na 2 O SiO 2 H 2 O), sodium silicate (Sodium silicate; NaO If the composition ratio of two or more chemicals selected from alkali chemicals such as nSiO 2 H 2 O) is less than 5wt%, the cleaning power to wash the mold is greatly reduced, whereas the cleaning power may be reduced even if the composition ratio is more than 32wt%. In addition, the mold for molding the resin eyeglass lens is a glass material, there is a problem that a groove is formed in the mold or a crack is generated locally.
또한 조성되는 폴리프로필렌 글리콜(Polypropylene glycol; nC3H8O2), 폴리에칠렌글리콜[Polyethylene glycol; HOCH2(CH2OCH2)nCH2OH], 헥실렌글리콜(Hexyleneglycol; C6H14O2)과 같은 고비점 알콜에서 선택한 2개이상의 약품조성비를 35wt%이상으로 조성되는 경우에는 그 이하의 조성비에 의하여서도 세척이 됨에도 불구하고 그 이상으로 조성하는 것은 비 경제적인 단점이 있었다.In addition, polypropylene glycol (Polypropylene glycol; nC 3 H 8 O 2 ), Polyethylene glycol [Polyethylene glycol; When two or more chemical composition ratios selected from high boiling alcohols such as HOCH 2 (CH 2 OCH 2 ) nCH 2 OH] and hexyleneglycol (C 6 H 14 O 2 ) are 35wt% or more, Despite being washed by the composition ratio, the composition was more economically disadvantageous.
그리고 그 조성비가 3wt%이하로 조성되는 경우에는 세척력의 저하로 인하여 금형에 묻은 수지가 떨어지지도 않아 세척이 되지 않게 된다.When the composition ratio is less than 3wt%, the resin deposited on the mold does not fall due to the deterioration of the washing power, and thus the washing is not performed.
계면활성제의 경우에는 비이온 계면활성제를 사용하고, 가장 적당한 것은 고급지방산(C12-C18)의 에틸렌 옥사이드 부가(EO-5-16)의 글리콜형태를 사용할 수 있다. 이러한 계면활성제는 분해된 오염물질을 유화, 분산시키는 작용을 하며 사용량은 보통 0.1 내지 10wt%가 적당하다. 사용량은 0.1wt%이하로 사용하면 분산능력이 미흡하고, 10wt%이상을 사용시 세정후 얼룩이 남을 문제점이 있다.In the case of surfactants, nonionic surfactants are used, and most preferably, glycol forms of ethylene oxide addition (EO-5-16) of higher fatty acids (C 12 -C 18 ) may be used. These surfactants act to emulsify and disperse the decomposed contaminants, and an amount of 0.1 to 10 wt% is usually appropriate. If the amount used is less than 0.1wt%, the dispersion capacity is insufficient, and when using more than 10wt%, there is a problem that stain remains after washing.
이러한 계면활성제의 보조역활을 위하여 필요에 의하여 선택적으로 모노에타놀아민(Monoethanolamine; H2NCH2CH2OH) 또는 트리에타놀아민(Triethanolamine; N(CH2CH2OH)3)을 사용할 수 있다.Monoethanolamine (H 2 NCH 2 CH 2 OH) or Triethanolamine (N (CH 2 CH 2 OH) 3 ) may optionally be used for the auxiliary role of the surfactant.
저비점 알콜인 에칠알콜(C2H5OH)과 메탄올(Methanol;CH3OH)을 각각 0.1∼10wt%식을 조성하게 되는 데 이러한 것은 교반후 수용액에 발생하는 수용액의 분리와 탁도를 제거하기 위하여 사용하게 된다.0.1 to 10 wt% of low-boiling ethanol (C 2 H 5 OH) and methanol (Methanol; CH 3 OH) are formulated to remove the separation and turbidity of the aqueous solution generated in the aqueous solution after stirring. Will be used.
이때 0.1wt%이하로 조성하는 경우에는 탁도가 여전히 발생하는 반면에 10wt%이상으로 조성하지 않아도 탁도의 제거 및 수용액의 분리가 발생하지 않아 그 이상으로 조성하는 것은 비 경제적이였다..At this time, when the composition was less than 0.1wt%, turbidity was still produced, whereas it was not economical to remove the turbidity and the separation of the aqueous solution even if the composition was not more than 10wt%.
이러한 본 발명에 있어서 상기의 조성비로 혼합함에 있어서 반드시 40℃이하로 냉각을 하여야하는데 이는 물과 가성가리(Potassium hydroxide; KOH), 가성소다(Sodium hydroxide; NaOH), 메타규산소다(Sodium silicate, Pentahydratte; Na2O SiO2H2O), 액규산소다(Sodium silicate; NaO nSiO2H2O)와 같은 알칼리약품을 혼합할 때 발생하는 열을 하강시켜서 고비점 알콜인 폴리프로필렌 글리콜(Polypropylene glycol; nC3H8O2), 폴리에칠렌글리콜[Polyethylene glycol; HOCH2(CH2OCH2)nCH2OH], 헥실렌글리콜(Hexylene glycol; C6H14O2)의 혼합시에 농도 및 색상의 변화를 방지하기 위하여 냉각시켜야 한다.In the present invention, when mixing at the above composition ratio, the temperature must be cooled to 40 ° C. or less, which is water and caustic (Potassium hydroxide; KOH), sodium hydroxide (NaOH), sodium metasilicate (Sodium silicate, Pentahydratte; Polypropylene glycol (NC), a high boiling alcohol, is reduced by lowering the heat generated when mixing alkaline chemicals such as Na 2 O SiO 2 H 2 O) and sodium silicate (NaO nSiO 2 H 2 O) 3 H 8 O 2 ), polyethylene glycol; When mixing HOCH 2 (CH 2 OCH 2 ) nCH 2 OH] and hexylene glycol (C 6 H 14 O 2 ), it should be cooled to prevent the change of concentration and color.

Turbidity was removed.
이러한 수용액과 종래에 사용하여 오던 세척법에 따라 물리적인 방법에 의하여 세척력을 비교하여 보았고, 그 비교예는 다음과 같았다.The washing power was compared by the physical method according to the aqueous solution and the washing method conventionally used, and the comparative example was as follows.
비교예 1Comparative Example 1
35℃를 유지하는 염화메틸렌(Methylene chloride)에 수지가 베어 있는 금형과 안경렌즈를 투입하여 초음파를 10분간 가한 다음 금형 및 렌즈를 꺼내어 다시 5% 알카리세제에 투입하여 초음파를 1분간 가한후, 금형과 랜즈를 꺼내어 물에 투입하여 초음파를 10분간 가한 후 수세한 다음 건조시켰다.Methylene chloride is maintained at 35 ° C, and the resin-bearing mold and the spectacle lens are put in the ultrasonic wave for 10 minutes, the mold and the lens are removed, and the mold and lens are put in 5% alkaline detergent and the ultrasonic wave is applied for 1 minute. The lens and the lens were taken out and put in water, sonicated for 10 minutes, washed with water, and dried.
이러한 세척과정을 거친 금형 및 안경렌즈를 육안으로 검사한 결과 금형의 테두리에 약간의 수지 및 이물질이 그대로 피착되어 있음을 발견할 수 있었고, 안경렌즈는 표면에 약간의 부식면이 발생된 것을 발견할 수 있었다.As a result of visual inspection of the mold and the spectacle lens after such a cleaning process, it was found that some resin and foreign substance was deposited on the edge of the mold as it was, and the spectacle lens was found to have some corrosion surface on the surface. Could.
그리고 작업중에 염화메틸렌의 휘발성으로 인하여 작업환경이 지극히 유해하였고, 특히 그 폐액을 별도로 처리하기 위하여 별도의 장치가 필요하였고, 현재 그로한 별도의 장치를 사용하고 있다.In addition, the working environment was extremely harmful due to the volatility of methylene chloride during the operation, and in particular, a separate device was needed to treat the waste liquid separately, and a separate device is currently used.

가성가리(KOH) 5wt%, 물 50wt%, 메타규산소다(Na2O SiO2H2O) 17wt%, 폴리프로필렌 글리콜(Polypropylene glycol; nC3H8O2), 폴리에칠렌글리콜[Polyethylene glycol; HOCH2(CH2OCH2)nCH2OH], 헥실렌글리콜(Hexylene glycol; C6H14O2),알킬 폴리 옥시 에텔 에테르(Alkyl polyoxy ethyl ether)을 각각 3wt%씩, 계면활성제로서 알킬폴리옥시 에틸에테르(C12-C18) 5wt% 및 에칠알콜(C2H5OH)과 메탄올(Methanol;CH3OH)을 각각 7wt%를 혼합한 세척제에 수지가 베어 있는 금형 및 안경렌즈를 투입하여 초음파를 10분간 가한 다음 금형과 안경렌즈를 꺼내어 다시 5% 알카리세제에 투입하여 초음파를 1분간 가한 다음 금형과 안경렌즈를 꺼내어 물에 투입하여 초음파를 10분간 가한 후 수세한 다음 건조시켰다.Caustic (KOH) 5 wt%, water 50 wt%, sodium metasilicate (Na 2 O SiO 2 H 2 O) 17 wt%, polypropylene glycol (polypropylene glycol; nC 3 H 8 O 2 ), polyethylene glycol [Polyethylene glycol; HOCH 2 (CH 2 OCH 2 ) nCH 2 OH], Hexylene glycol (C 6 H 14 O 2 ), Alkyl polyoxy ethyl ether (3wt%) each, alkylpoly as a surfactant A resin-containing mold and spectacle lens were added to a cleaning agent mixed with 5 wt% of oxy ethyl ether (C 12- C 18 ) and 7 wt% of ethanol (C 2 H 5 OH) and methanol (Methanol; CH 3 OH). After the ultrasonic wave was added for 10 minutes, the mold and the spectacle lens were taken out, and then put into the 5% alkaline detergent, the ultrasonic wave was added for 1 minute, the mold and the spectacle lens were taken out and put into water, the ultrasonic wave was added for 10 minutes, washed with water, and dried.
이러한 세척과정을 거친 금형과 렌즈를 육안으로 검사한 결과 금형에 피착된 수지를 발견할 수 없었고, 또한 안경렌즈에는 이물질이 전혀 피착되어 있지 않았을 뿐만 아니라 그 표면에 부식이 발생하지 않아 그 만큼 생산성을 향상시킬 수 있었고, 상기한 세척제는 수용성이여서 환경오염의 문제를 발생시키지는 않았다.As a result of visual inspection of the mold and lens that went through this cleaning process, the resin deposited on the mold could not be found. Also, there was no foreign matter deposited on the spectacle lens, and corrosion was not generated on the surface. It was possible to improve and the above-mentioned cleaning agent was water soluble so that it did not cause the problem of environmental pollution.
이상 상기에서 살펴본 바와 같이 본 발명에 의한 세척제는 수용성이므로 친 환경적이면서도 수지 안경렌즈 및 금형에 뭍어있는 수지에 침투하여 이를 팽창시켜 생분해함으로서 금형의 세척력을 증대시키고, 안경렌즈에 이물질의 피착이 발생되지 않았고, 특히 안경렌즈의 표면을 부식시키지 않으므로 생산성을 향상시킬 수 있는 매우 유용한 발명임이 분명하다.As described above, since the cleaning agent according to the present invention is water-soluble, it penetrates into the resin spectacle lens and the resin stuck to the mold and expands the biodegradation to increase the washing power of the mold, and the deposition of foreign matter on the spectacle lens. It is obvious that the invention is a very useful invention that can improve productivity since it does not corrode the surface of the spectacle lens.
