Description
本発明は、プラスチックレンズ用洗浄剤組成物と、これを用いたプラスチックレンズの製造方法に関する。 The present invention relates to a cleaning composition for plastic lenses and a method for producing a plastic lens using the same.
眼鏡レンズ等のプラスチックレンズ基材の成形には、一般的に、１対の成形型が用いられる。この１対の成形型が、テープまたはガスケット等のシール材によりシールされることにより、シール材と１対の成形型とで囲まれたキャビティーが形成される。このキャビティーにモノマー等を注入し、モノマーを重合および硬化させることによりプラスチックレンズ基材が得られる。得られたプラスチックレンズ基材は、例えば、その外周について研磨され、洗浄され、アニーリングを経て、次に、その内面が研磨され、その後、洗浄される。外周を研磨する際および内面を研磨する際には、プラスチックレンズ基材はテープを用いてレンズ固定冶具に一時的に固定される。一方、成形型については、脱型後、洗浄され、複数のプラスチックレンズ基材を成形するために何度も繰り返し使用される。 In general, a pair of molds is used for molding a plastic lens substrate such as an eyeglass lens. The pair of molding dies are sealed with a sealing material such as a tape or a gasket, so that a cavity surrounded by the sealing material and the pair of molding dies is formed. A plastic lens substrate is obtained by injecting a monomer or the like into the cavity and polymerizing and curing the monomer. The obtained plastic lens base material is polished, cleaned, and annealed, for example, on the outer periphery, and then the inner surface is polished and then cleaned. When polishing the outer periphery and the inner surface, the plastic lens substrate is temporarily fixed to the lens fixing jig using a tape. On the other hand, the mold is washed after demolding and repeatedly used many times to mold a plurality of plastic lens substrates.
プラスチックレンズの製造工程において、プラスチックレンズ基材を成形型から離型した後、プラスチックレンズ基材に対して表面コーティングがなされるまでの間、プラスチックレンズ基材の表面には種々の汚れが付着する。上記汚れとしては、例えば、離型時にプラスチックレンズ基材に付着したオリゴマー状若しくはポリマー状の、プラスチックレンズ原料由来の樹脂汚れ（以下、「樹脂汚れ」ともいう。）、ガスケットからの転写成分（例えば、ガスケットからブリードアウトした可塑剤）、テープからの転写粘着物、外周研削や面取り時に付着した、高分子化合物からなる樹脂粉、指紋、その他雰囲気中のほこりなどがある。上記樹脂汚れは、モノマーをキャビティー内に注入した時にこぼれたプラスチックレンズ原料（未重合物）や、このプラスチックレンズ原料に付着した上記樹脂粉等を含む。 In the manufacturing process of a plastic lens, after the plastic lens substrate is released from the mold, various stains adhere to the surface of the plastic lens substrate until the surface is coated on the plastic lens substrate. . Examples of the stain include resin stains derived from plastic lens raw materials (hereinafter also referred to as “resin stain”) attached to the plastic lens substrate at the time of release, and transfer components from the gasket (for example, , A plasticizer bleeded out from the gasket), a transfer adhesive from the tape, resin powder made of a polymer compound adhered during peripheral grinding or chamfering, fingerprints, and other dust in the atmosphere. The resin stain includes a plastic lens raw material (unpolymerized) spilled when the monomer is injected into the cavity, the resin powder attached to the plastic lens raw material, and the like.
これらの汚れの内、上記樹脂汚れは、強い粘着性を有しているため、プラスチックレンズ基材に強固に付着している。加えて、樹脂汚れと被洗浄物（プラスチックレンズ基材）とが、同質、即ち、類似又は同じ化学組成を有していることから、プラスチックレンズ基材を腐食する等の悪影響を及ぼすことなく樹脂汚れを除去することは容易ではない。指紋は、極性が小さく、油状であることから、樹脂汚れに対するのとは異なって、洗浄剤組成物が、指紋を溶解可能であることが重要である。ほこりに対しては、洗浄剤組成物がほこりの再付着を防止できることが重要である。この様に、プラスチックレンズ基材の表面に付着した種々の汚れには、除去が容易ではない汚れが含まれる上、相互に特性の異なる汚れが含まれるので、１種類の洗浄剤組成物のみを用いて洗浄を行うことにより、コーティング直前等において要求される高度に清浄な表面を得るのはきわめて困難である。 Among these stains, the resin stain has strong adhesiveness, and is thus firmly attached to the plastic lens substrate. In addition, since the resin dirt and the object to be cleaned (plastic lens base material) have the same quality, that is, similar or the same chemical composition, the resin does not adversely affect the plastic lens base material. It is not easy to remove the dirt. Since the fingerprint is small in polarity and oily, it is important that the cleaning composition is capable of dissolving the fingerprint unlike the resin stain. For dust, it is important that the cleaning composition can prevent re-deposition of dust. In this way, the various stains attached to the surface of the plastic lens substrate include stains that are not easy to remove, and also include stains having different characteristics from each other, so only one type of cleaning composition is used. It is extremely difficult to obtain a highly clean surface required immediately before coating, etc. by performing cleaning using the same.
このような背景下、樹脂汚れやほこり等、特性の異なった２種以上の汚れに対しても良好な洗浄性を有する洗浄剤組成物が、特許文献１や特許文献２等に開示されている。
しかし、特許文献２に具体的に記載された洗浄剤組成物（同文献の表１参照）をそのままプラスチックレンズ基材の洗浄に使用しても、特に、プラスチックレンズ基材を研磨する際に、プラスチックレンズ基材をレンズ固定冶具に仮止めするために（一時的に固定するために）使用するテープ由来の転写粘着物（以下、「粘着物汚れ」とも呼ぶ）等については、完全に除去できないことが判明した。 However, even when the cleaning composition specifically described in Patent Document 2 (see Table 1 of the same document) is used as it is for cleaning a plastic lens substrate, particularly when polishing the plastic lens substrate, The tape-derived transfer adhesive (hereinafter also referred to as “adhesive dirt”) used to temporarily fix the plastic lens substrate to the lens fixing jig cannot be completely removed. It has been found.
本発明は、プラスチックレンズ基材に付着した各種の汚れに対し汎用的に用いることができ、特に粘着物汚れを容易に除去できるプラスチックレンズ用洗浄剤組成物と、これを用いたプラスチックレンズの製造方法を提供する。 INDUSTRIAL APPLICABILITY The present invention can be used universally for various types of dirt adhered to a plastic lens substrate, and in particular, a plastic lens cleaning composition that can easily remove adhesive dirt, and production of plastic lenses using the same. Provide a method.
本発明のプラスチックレンズ用洗浄剤組成物は、アルカリと、アルキルグリコシドと、グリセリルエーテルと、炭化水素と、水とを含有し、前記組成物中、前記アルカリの含有量が、３〜８重量％であり、前記アルキルグリコシドの含有量が、８〜１８重量％であり、前記アルキルグリコシドの含有量を前記グリセリルエーテルの含有量で除した値が、３〜４である。 The plastic lens cleaning composition of the present invention contains an alkali, an alkyl glycoside, a glyceryl ether, a hydrocarbon, and water, and the content of the alkali in the composition is 3 to 8% by weight. The content of the alkyl glycoside is 8 to 18% by weight, and the value obtained by dividing the content of the alkyl glycoside by the content of the glyceryl ether is 3 to 4.
本発明のプラスチックレンズの製造方法は、洗浄剤組成物を用いてプラスチックレンズ基材を洗浄する洗浄工程を含み、前記洗浄剤組成物は、本発明のプラスチックレンズ用洗浄剤組成物である。 The manufacturing method of the plastic lens of this invention includes the washing | cleaning process of wash | cleaning a plastic lens base material using a cleaning composition, The said cleaning composition is the cleaning composition for plastic lenses of this invention.
本発明のプラスチックレンズ用洗浄剤組成物では、プラスチックレンズ基材に付着した各種の汚れに対し汎用的に用いることができ、特に、粘着物汚れを容易に除去できる。そのため、例えば、プラスチックレンズ基材の洗浄工程を簡略化できる。 In the cleaning composition for plastic lenses of the present invention, it can be used for various kinds of stains attached to the plastic lens substrate, and in particular, the adhesive stains can be easily removed. Therefore, for example, the cleaning process of the plastic lens substrate can be simplified.
本発明のプラスチックレンズの製造方法では、本発明のプラスチックレンズ用洗浄剤組成物を用いてプラスチックレンズ基材を洗浄する工程を含むため、プラスチックレンズ基材の洗浄工程を簡略化できる。 Since the method for producing a plastic lens of the present invention includes a step of washing the plastic lens substrate using the plastic lens cleaning composition of the present invention, the washing step of the plastic lens substrate can be simplified.
本発明のプラスチックレンズ用洗浄剤組成物（以下、単に洗浄剤組成物ともいう。）は、アルカリと、アルキルグリコシドと、グリセリルエーテルと、炭化水素と、水とを含有し、アルカリ、アルキルグリコシド及びグリセリルエーテルの特定の含有量において、プラスチックレンズ基材に付着する粘着物汚れを顕著に除去できるものである。また、本発明の洗浄剤組成物は、アルキルグリコシドとグリセリルエーテルの両方を含んでいるので、本来水に溶解しない、オレフィン系炭化水素やパラフィン系炭化水素等の炭化水素を、すすぎ時のような高含水域でも分散させることができる。したがって、プラスチックレンズ基材の表面上に存在する、親水性のみならず新油性の、各種の汚れ（例えば、指紋等の油性汚れ、ほこり等の無機汚れ等）を容易に溶解し除去することが可能である。よって、プラスチックレンズ基材を洗浄する工程において本発明の洗浄剤組成物を用いれば、１種の洗浄剤組成物で上記各種の汚れを除去できるので、洗浄に要するコストを大きく低減できる。さらに、本発明の洗浄剤組成物は、従来の洗浄剤に比べ、引火性を考慮した厳密な水分管理を行う必要がなく扱いやすい。 The plastic lens cleaning composition of the present invention (hereinafter also simply referred to as a cleaning composition) contains an alkali, an alkyl glycoside, a glyceryl ether, a hydrocarbon, and water, and contains an alkali, an alkyl glycoside, and With a specific content of glyceryl ether, it is possible to remarkably remove the adhesive dirt adhering to the plastic lens substrate. In addition, since the cleaning composition of the present invention contains both alkylglycoside and glyceryl ether, hydrocarbons such as olefinic hydrocarbons and paraffinic hydrocarbons that do not inherently dissolve in water, such as during rinsing. It can be dispersed even in high water content areas. Therefore, it is possible to easily dissolve and remove various kinds of dirt (for example, oily dirt such as fingerprints and inorganic dirt such as dust) existing on the surface of the plastic lens substrate, which are not only hydrophilic but also new oily. Is possible. Therefore, if the cleaning composition of the present invention is used in the step of cleaning the plastic lens substrate, the above-mentioned various types of dirt can be removed with one cleaning composition, so that the cost required for cleaning can be greatly reduced. Furthermore, the cleaning composition of the present invention is easier to handle than the conventional cleaning agents because it is not necessary to perform strict moisture management considering flammability.
また、従来の炭化水素を含む水系洗浄剤を用いた場合は、被洗浄物に付着した洗浄成分がすすぎ槽に持ちこまれると白濁することから、被洗浄物から洗浄成分を洗い流す際のすすぎ時の負荷が大きかった。しかし、本発明の洗浄剤組成物は、炭化水素をすすぎ時のような高含水域でも安定に分散させることができるので、希釈しても透明であり、洗浄後のすすぎ工程の負荷を大幅に低減させることが可能となる。 In addition, when a conventional water-based cleaning agent containing hydrocarbons is used, the cleaning component adhering to the object to be cleaned becomes cloudy when brought into the rinsing tank. The load was great. However, since the cleaning composition of the present invention can stably disperse hydrocarbons even in a high water content region such as when rinsing, it is transparent even when diluted, and the load of the rinsing process after cleaning is greatly increased. It can be reduced.
更に本発明の洗浄剤組成物によれば、後述するように、アルキルグリコシドとグリセリルエーテルとの特定比率においてアルカリと組み合わせることにより、アルキルグリコシド単独よりも表面張力を下げ、油汚れに対する浸透力および溶解力を高めることが可能となるだけでなく、アルキルグリコシドによる乳化力、すすぎ易さを維持できる。すなわち、本発明の洗浄剤組成物は、所定量のアルキルグリコシドを含むので高い乳化力を有し、すすぎ易さも良好である。 Furthermore, according to the cleaning composition of the present invention, as will be described later, by combining with an alkali at a specific ratio of alkylglycoside and glyceryl ether, the surface tension is lowered as compared with the alkylglycoside alone, and the penetrating power and solubility to oil stains are reduced. Not only can the power be increased, but also the emulsifying power and ease of rinsing with the alkyl glycoside can be maintained. That is, since the detergent composition of the present invention contains a predetermined amount of alkyl glycoside, it has high emulsifying power and is easy to rinse.
なお、本発明の洗浄剤組成物は、低温でも十分な洗浄性能を有するが、特に５０℃以上の温度において高い洗浄性能を有する。 The cleaning composition of the present invention has sufficient cleaning performance even at a low temperature, but has high cleaning performance particularly at a temperature of 50 ° C. or higher.

（１）試料約０．３ｇを試験管に採取した。（２）この試験管を１００±５℃に設定したブロックヒーターにて加熱し、試料の水分を蒸発させた。（３）そして、試験管内に、無水酢酸：ピリジン＝１：１（重量比）の溶液を５ｍＬ加え、混合した。（４）次いで、試験管を１００±５℃に設定したブロックヒーターにて９０分間加熱し、アセチル化反応を行った。（５）その後、この試験管を１００±５℃に設定したブロックヒーターにて窒素を吹き込みながら加熱し、試験管内の無水酢酸及びピリジンを蒸発させた。（６）続いて、無水酢酸及びピリジンを蒸発させた後の試験管内にトルエンを５ｍＬ加え、アセチル化物と十分に混合し、アセチル化物をトルエンに溶解させた。（７）その後、窒素を吹き込みながら、この試験管を１００±５℃に設定したブロックヒーターにて加熱し、試験管内のトルエンを蒸発させた。（８）（６）〜（７）の操作を３回行った。（９）その後、トルエンを蒸発させた後の試験管内にテトラヒドロフラン（特級）を３ｍＬ加え、アセチル化物と十分に混合し、アセチル化物をテトラヒドロフランに溶解させた。（１０）そして、得られた溶解液から、メッシュ径０．２μｍのフィルターを用いて不溶物を除去し、高速液体クロマトグラフ法（ＨＰＬＣ）による測定を行った。 (1) About 0.3 g of a sample was collected in a test tube. (2) The test tube was heated with a block heater set to 100 ± 5 ° C. to evaporate the moisture in the sample. (3) Then, 5 mL of a solution of acetic anhydride: pyridine = 1: 1 (weight ratio) was added to the test tube and mixed. (4) Next, the test tube was heated with a block heater set at 100 ± 5 ° C. for 90 minutes to carry out an acetylation reaction. (5) Then, this test tube was heated while blowing nitrogen with a block heater set at 100 ± 5 ° C. to evaporate acetic anhydride and pyridine in the test tube. (6) Subsequently, 5 mL of toluene was added to the test tube after evaporating acetic anhydride and pyridine, and the mixture was sufficiently mixed with the acetylated product to dissolve the acetylated product in toluene. (7) Then, while blowing nitrogen, this test tube was heated with a block heater set to 100 ± 5 ° C. to evaporate toluene in the test tube. (8) The operations (6) to (7) were performed three times. (9) Thereafter, 3 mL of tetrahydrofuran (special grade) was added to the test tube after evaporating toluene, and the mixture was sufficiently mixed with the acetylated product to dissolve the acetylated product in tetrahydrofuran. (10) Then, insoluble matters were removed from the obtained solution using a filter having a mesh diameter of 0.2 μm, and measurement was performed by high performance liquid chromatography (HPLC).
得られたＨＰＬＣチャートの各ピークに相当するアセチル化したアルキルグリコシドの分子量を質量分析法で測定した。そして、得られた分子量に基づき、ＨＰＬＣチャートの各ピークに各糖縮重合度のアセチル化したアルキルグリコシドを振り当てた。更に、各ピーク面積を上記検出器に付属するコンピュータにより算出した。 The molecular weight of the acetylated alkyl glycoside corresponding to each peak of the obtained HPLC chart was measured by mass spectrometry. And based on the obtained molecular weight, the acetylated alkyl glycoside of each sugar condensation polymerization degree was allocated to each peak of a HPLC chart. Further, each peak area was calculated by a computer attached to the detector.
続いて、以下に示す計算式を用いて糖縮重合度を算出した。なお、以下において、ＡＧ-nは、糖縮重合度ｎ（ｎ＝１，２・・・・）のアセチル化したアルキルグリコシドを示す。また、Ｓnは、糖縮重合度ｎ（ｎ＝１，２・・・・）のアセチル化したアルキルグリコシドが振り当てられたＨＰＬＣピークの面積を示す。 Subsequently, the degree of sugar condensation polymerization was calculated using the following formula. In the following, AG 1 -n represents an acetylated alkyl glycoside having a degree of sugar condensation polymerization n (n = 1, 2,...). Further, S n represents an acetylated area of HPLC peaks alkylglycoside is allotted thereto with the Tochijimi polymerization degree n (n = 1,2 ····).
（糖縮重合度を求めるための計算式）
ＡＧ-1の分子量＝〔アセチル化したグルコースの分子量−ＯＨの分子量〕＋Ｒ1ＯＨの分子量＝３３１．２＋１７２．３＝５０３．５
ＡＧ-2の分子量＝ＡＧ-1の分子量＋さらに縮合したグルコースのアセチル化物の分子量＝ＡＧ-1の分子量＋２８８
同様に、ＡＧ-nの分子量＝ＡＧ-(n-1)の分子量＋２８８
ＡＧ-nのモル比＝Ｓn／ＡＧ-nの分子量／Σ（Ｓi／ＡＧ-iの分子量）
糖縮重合度＝Σ（ＡＧ-jのモル比×ｊ）
なお、アセチル化したグルコースの分子式はＣ14Ｈ20Ｏ10で、縮合したグルコースのアセチル化物の分子式はＣ12Ｈ16Ｏ8である。
(Calculation formula for determining the degree of sugar condensation polymerization)
Molecular weight of AG- 1 = [molecular weight of acetylated glucose−molecular weight of OH] + molecular weight of R 1 OH = 331.2 + 172.3 = 503.5
Molecular weight of AG -2 = molecular weight of AG -1 + molecular weight of further condensed acetylated glucose = molecular weight of AG -1 +288
Similarly, molecular weight of AG −n = molecular weight of AG − (n−1) +288
AG −n molar ratio = S n / AG −n molecular weight / Σ (S i / AG −i molecular weight)
Sugar polycondensation degree = Σ (molar ratio of AG- j × j)
The molecular formula of acetylated glucose is C 14 H 20 O 10 , and the molecular formula of condensed acetylated glucose is C 12 H 16 O 8 .
上記計算式にて得られた数値を以下の表２に示す。なお五量体（ＡＧ-5）はＨＰＬＣにおいて検出されなかった。 The numerical values obtained by the above calculation formula are shown in Table 2 below. The pentamer (AG -5 ) was not detected by HPLC.
表２より、本実施例で使用したアルキルグリコシドの糖縮重合度（ｙ）は、ｙ＝ＡＧ-1のモル比＋ＡＧ-2のモル比×２＋ＡＧ-3のモル比×３＋ＡＧ-4のモル比×４＝１．４３により算出された。 From Table 2, the degree of sugar polycondensation (y) of the alkyl glycoside used in this example is y = AG −1 molar ratio + AG −2 molar ratio × 2 + AG −3 molar ratio × 3 + AG −4 molar ratio. It was calculated by x4 = 1.43.
