Definitions
- the present invention relates to a plastic lens manufacturing method and a plastic lens manufacturing apparatus.
- Plastic lenses which have a higher refractive index and a higher Abbe number than inorganic lenses, are light and difficult to break, and can be dyed, so they are rapidly spreading to optical materials such as eyeglass lenses and camera lenses.
- Various types of molded articles for lenses have been developed and used so far, and a typical example among them is an optical molded article obtained from a polymerizable composition containing an isocyanate compound and a thiol compound (Patent Document 1). ).
- Plastic lenses are usually prepared by once preparing a polymerizable composition by stirring and mixing a polymerization reactive compound (hereinafter referred to as a polymerization monomer or monomer) and an additive in one preparation tank, and then a glass mold and a tape. Alternatively, it is manufactured by a casting polymerization method in which a polymerizable composition is injected into a cavity of a lens mold formed by a resin gasket and polymerized and cured by heating or emitting radiation.
- a polymerization reactive compound hereinafter referred to as a polymerization monomer or monomer
- the striae may be caused by injection traces when the polymerizable composition is injected into the lens mold, or flow traces where the polymerizable composition convects due to the effects of monomer heat generation or temperature difference from the surroundings during polymerization. Something that might cause is considered.
- the polymerizable composition When manufacturing a plastic lens industrially in large quantities, the polymerizable composition is usually transferred from a preparation tank to an injection nozzle into a lens mold through a resin pipe or the like. At this time, in particular, in a polymerizable composition having a short pot life and a polymerizable composition having a high viscosity at the time of preparation, an injection mark is generated, which causes a problem of causing striae. there were. In particular, in industrial production of plastic lenses, when these polymerizable compositions are prepared in large quantities, striae due to injection marks are likely to occur, and there is a problem that the yield of products in lens production decreases. It was.
- Patent Document 3 a method for producing a plastic lens in which a polymerization monomer is mixed with a motor-equipped mixing / discharging device in Patent Document 2 and a polymerizable composition is continuously injected into a plurality of lens molds has been proposed (Patent Document 3). ).
- the monomer is slowly cured over a long period of time so that the monomer does not flow, or underwater polymerization to increase heat conduction And so on.
- Patent Document 4 a method in which a monomer composition is pre-reacted and thickened to a specific range and then polymerized and cured by a temperature rising polymerization program similar to the conventional manufacturing method (Patent Document 4), a process of polymerizing and curing a monomer composition On the way, the molded body filled with the monomer composition is forcibly and regularly moved irregularly to eliminate the unevenness of the monomer during curing and suppress the occurrence of optical distortion or striae.
- Patent Document 5 Method of optimizing a temperature program for polymerizing a monomer composition
- Patent Document 6 Method of optimizing a temperature program for polymerizing a monomer composition
- Patent Document 7 Method of curing at a specific angle
- Patent Document 7 a method of polymerizing by irradiating microwaves in a state in which a mold filled with a monomer composition is immersed in a liquid
- JP-A-63-046213 JP 2014-166706 A International Publication No. 2010/050239 Pamphlet JP 2007-90574 A JP 2007-261054 A JP 2009-226742 A JP 2011-207152 A JP 2014-141033 A
- Patent Documents 2 to 3 If the conventional methods described in Patent Documents 2 to 3 are used, even a polymerizable composition having a short pot life can be immediately injected into the cavity of the lens mold after monomer preparation. There is a possibility that plastic lenses with reduced striae can be produced.

本発明のプラスチックレンズの製造装置は、
重合反応性化合物を含む溶液を撹拌混合して重合性組成物を調製する撹拌手段、および得られた前記重合性組成物を吐出する吐出口を備える調合槽と、

前記配管の少なくとも一部に設置され、前記調合槽から吐出された前記重合性組成物を再混合するとともに前記レンズ注型用鋳型内に注入する混合手段と、を備える。
<プラスチックレンズの製造装置>
図1に示すように、本実施形態のプラスチックレンズの製造装置10は、重合反応性化合物を含む溶液を撹拌混合して重合性組成物を調製する撹拌手段22、および得られた前記重合性組成物を吐出する吐出口24を備える調合槽20と、
注入口32を備え、注入口32を介して内部に移送された前記重合性組成物を硬化して成形体を得るレンズ注型用鋳型30と、
吐出口24および注入口32を連結し、調合槽20内の前記重合性組成物をレンズ注型用鋳型30内に移送する配管40と、
配管40に設置され、調合槽20から吐出された前記重合性組成物を混合しながら送液し、レンズ注型用鋳型30のキャビティー38に注入する混合器50と、を備える。
調合槽20はステンレス鋼材等から構成することができる。撹拌手段22は上部が駆動部に接続されており、所定の回転数で回転させることができる。
固定部材34は、注入口32を備えており、注入口32を介してレンズ注型用鋳型30のキャビティー38に重合性組成物を注入することができる。
混合器50としては、静止型混合器または動的混合器を挙げることができる。
本実施形態のプラスチックレンズの製造方法は以下の工程を含む。
工程a:重合反応性化合物を含む溶液を調合槽20の内部26で撹拌して混合する。
工程b:工程aにより得られた重合性組成物を調合槽20から吐出するとともに混合器50に送液し、次いで混合器50内に通過させることにより重合性組成物を再混合しながら送液する。そして、レンズ注型用鋳型30のキャビティー38内に注入する。
工程c:レンズ注型用鋳型30において重合性組成物を硬化する。
工程d:硬化した樹脂をレンズ注型用鋳型30から離型してプラスチックレンズ成形体を得る。
本実施形態のプラスチックレンズの製造方法は、重合性組成物を再混合しながら送液し、レンズ注型用鋳型内に注入する工程を備えており、特に、ポットライフが短く粘度が上昇し易い重合性組成物や、調合時に高粘度になる重合性組成物であってもレンズ注型用鋳型30のキャビティー38への注入直前に再度混合することにより注入痕が原因となる脈理を著しく低減することができる。
重合反応性化合物やその他の成分を添加する順序や添加速度は特に制限はなく、任意に設定することができる。
重合反応性化合物を含む溶液は、容量や撹拌羽根の形状等により適切な条件が変化するが、攪拌手段22により攪拌速度50~500rpm程度で、0.5~1.0時間程度の間、攪拌される。また、攪拌時の溶液の温度は10~20℃程度である。
重合性組成物を調製した後、減圧下での脱泡処理が行われる。
本発明の効果の観点から、工程aで調製された重合性組成物の20℃における粘度は、好ましくは10~1000mPa・s、さらに好ましくは50~1000mPa・s、特に好ましくは50~500mPa・sとすることができる。粘度は、B型粘度計(ブルックフィールド社/型番:LVT、ローターNo.2、ローター回転数30rpm)を使用して測定することができる。
工程aにより得られた重合性組成物は、調合槽20から吐出口24を介して吐出され、配管40を通って混合器50に送液される。
調合槽20から吐出するには、内部26の圧力を利用することができる。また、調合槽20に設けられた図示しないポンプを用いて吐出することもできる。吐出量は混合器50の処理能力に基づいて、バルブ42で調整され、連続的に吐出してもよく、断続的に吐出してもよい。なお、配管40に設けられた濾過装置により、重合性組成物を濾過することができる。
そして、混合器50を通過した重合性組成物は、注入口32を介してレンズ注型用鋳型30のキャビティー38内に注入される。なお、レンズ注型用鋳型30内に注入する際の重合性組成物の粘度を下記範囲とするために、混合器50からレンズ注型用鋳型30への送液は短時間で行うことが好ましい。つまり、本実施形態のプラスチックレンズの製造装置は、混合器50の吐出口とレンズ注型用鋳型30の注入口32との距離が短くなるように構成されることが好ましい。
この粘度範囲にある重合性組成物であれば、レンズモールドのキャビティー内に重合性組成物を注入する場合、注入痕の発生をより抑制し、結果として脈理の発生を効果的に抑制することができる。
次いで、レンズ注型用鋳型30のキャビティー38に注入された重合性組成物を硬化する。
具体的には、まず、重合性組成物が注入されたレンズ注型用鋳型30をオーブンや温水中等の加熱可能装置内で、加熱、あるいは活性エネルギー線を照射して重合を行うことで重合硬化し、樹脂化する。
通常、0℃から40℃の範囲の温度で開始し、その後徐々に80℃から150℃の範囲にまで昇温させ、その温度で1時間から6時間加熱したのち徐冷するのが一般的である。
なお、レンズ注型用鋳型30のキャビティー38内に偏光フィルムを固定しておき、プラスチック偏光レンズを製造することもできる。
硬化した樹脂をレンズ注型用鋳型30から離型し、凸面を備えるプラスチックレンズ成形体を得ることができる。なお、プラスチックレンズ成形体の厚みは通常0.1~100mm程度である。
さらに、本実施形態で得られるプラスチックレンズは、必要に応じ、外周研磨、裏面研磨、帯電防止処理、染色処理、調光処理等を施してもよい。
このようなプラスチックレンズは、メガネ用のレンズ、特に視力補正用レンズとして有用である。

注入口32を備え、注入口32を介して内部に移送された前記重合性組成物を硬化して成形体を得るレンズ注型用鋳型30と、
吐出口24および注入口32を連結し、調合槽20内の前記重合性組成物をレンズ注型用鋳型30のキャビティー38内に移送する配管40と、

調合槽20はステンレス鋼材等から構成することができる。撹拌手段62は上部が駆動部に接続されており、所定の回転数で回転させることができる。
本実施形態のプラスチックレンズの製造方法は以下の工程を含む。
工程i:重合反応性化合物を含む溶液を調合槽20の内部26で撹拌混合する。
工程ii:工程iにより得られた重合性組成物を調合槽20から吐出するとともに混合槽60に送液し、次いで混合槽60で重合性組成物を攪拌して再混合する。そして、レンズ注型用鋳型30のキャビティー38内に注入する。
工程iii:レンズ注型用鋳型30において重合性組成物を硬化する。
工程iv:硬化した樹脂をレンズ注型用鋳型30から離型してプラスチックレンズ成形体を得る。
本実施形態のプラスチックレンズの製造方法は、重合性組成物を攪拌して再混合し、レンズ注型用鋳型内に注入する工程を備えており、ポットライフが短く粘度が上昇し易い重合性組成物や、調合時に高粘度になる重合性組成物であってもレンズ注型用鋳型30のキャビティー38への注入直前に再度混合することにより注入痕が原因となる脈理を著しく低減することができる。
工程iにより得られた重合性組成物は、調合槽20から吐出口24を介して吐出され、配管40を通って混合槽60に送液される。
調合槽20から吐出するには、内部26の圧力を利用することができる。また、調合槽20に設けられた図示しないポンプを用いて吐出することもできる。吐出量は混合槽60の処理能力に基づいて、バルブ42で調整され、連続的に吐出してもよく、断続的に吐出してもよい。なお、配管40に設けられた濾過装置により、重合性組成物を濾過することができる。
重合性組成物を攪拌して再混合した後、減圧下での脱泡処理を再度行うことができる。
再混合された重合性組成物は、吐出口64を介して吐出され、注入口32を介してレンズ注型用鋳型30のキャビティー38に注入される。なお、レンズ注型用鋳型30内に注入する際の重合性組成物の粘度を下記範囲とするために、混合槽60からレンズ注型用鋳型30への送液は短時間で行うことが好ましい。つまり、本実施形態のプラスチックレンズの製造装置は、混合槽60の吐出口64とレンズ注型用鋳型30の注入口32との距離が短くなるように構成されることが好ましい。
この粘度範囲にある重合性組成物であれば、レンズモールドのキャビティー内に重合性組成物を注入する場合、注入痕の発生をより抑制し、結果として脈理の発生を効果的に抑制することができる。
例えば、第1実施形態において、2つ以上の混合器50を直列に備えるプラスチックレンズの製造装置を用いることもでき、また第2実施形態において、2つ以上の混合槽60を直列に備えるプラスチックレンズの製造装置を用いることもできる。さらに、1つ以上の混合器50と1つ以上の混合槽60とを直列に備えるプラスチックレンズの製造装置を用いることもできる。

続いて重合性組成物が注入されたモールド型を、重合オーブンへ投入、20℃~140℃まで50時間かけて徐々に昇温して重合した。重合終了後、オーブンからモールド型を取り出し、キャビティー内から成形体を離型し、レンズを得た。
得られた100枚の各レンズの脈理の有無を観察したところ、脈理が発生し易い中心厚10mmのレンズにおいて、脈理は全く確認されなかった。また、調製後のレンズから任意に1枚を選択してアニール処理し樹脂の性状測定を行ったところ、外観が○、屈折率(ne)1.602、アッベ数(νe)39、Tg140℃で良好な物性を示した。
実施例3と同様の調合操作にて重合性組成物を得たのち、1.8μPTFE製フィルターにて加圧方式によるろ過を行いながら別の中継槽に移し、パドル翼が装着された攪拌機にて撹拌速度200rpmで20℃において3分間撹拌を行った。これを実施例3で使用した同形状のキャビティー内に20℃において5g/秒の速度で直接注入した後、重合を行い、レンズを得た。注入時の重合性組成物の粘度は、90mPa・sであった。

実施例1における送液ラインにおいて、スタティックミキサーを設置せず、吐出口径2.4mmの汎用注入ノズルで、モールド型のキャビティー内に重合性組成物を注入した以外は実施例1と同様の操作でレンズを得た。得られた各レンズ100枚の脈理の有無を観察したところ、全てのレンズで脈理が確認された。また、調製後のレンズから任意に1枚を選択してアニール処理し樹脂の性状測定を行ったところ、外観が○、屈折率(ne)1.602、アッベ数(νe)39、Tg140℃で良好な物性を示した。
