Description

【産業上の利用分野】
本発明はエポキシ部分エステル化物の製造方法に関する。詳細には得られるエポキシ部分エステル化物が貯蔵安定性に優れ液晶封止用途に好適に用いる事の出来るエポキシ部分エステル化物の製造方法に関する。
【0002】
【従来の技術】
従来からビスフェノールA型エポキシ樹脂とアクリル酸またはメタクリル酸とから誘導される多価アクリレート化物または多価メタクリレート化物の製造方法は知られており、例えば特許2593019号では3価のリン化合物を触媒とするエポキシエステルの製造方法が知られるが、エポキシエステル合成後は3価の触媒を酸化させることで不活性化させ、貯蔵安定性を付与させる方法が提案されている。しかし該製造方法では触媒不活性処理を必須とする課題がある。また、特開平11−21333号公報には、有機硫黄化合物を触媒として用いてなるエポキシエステルの製造方法が提案されている。その方法によれば、合成段階でエポキシ基とカルボキシル基とが安定に共存でき貯蔵安定性が飛躍的に向上したエポキシエステルが製造できるとしている。
しかしながら、公知技術には合成物がエポキシ基とアクリレート基および/またはメタクリレート基を高濃度で含有してなる貯蔵安定性に優れたエポキシ部分エステル化物の製造方法が見当たらない。(特許文献1、2)

【発明が解決しようとする問題点】
本発明の目的は、貯蔵安定性に優れると同時に電子分野の塗料用途ならびに接着シール用途に好適に用いることのできるラジカル重合ならびに熱硬化の両方の硬化機能を持つエポキシ部分エステル化物の製造方法を提供することである。
【0006】
【問題点を解決するための手段】
本発明者らは、本発明の問題点を解決するために鋭意検討を行なった結果、エポキシ部分エステル化物の製造に際し、付加反応触媒として3級アミンを、また重合禁止剤としてフェノチアジンをそれぞれ用いることで前記課題が解決できることを見出し、本発明を達成した。
【0007】
すなわち、本発明とは、エポキシ樹脂のエポキシ基1当量に対してアクリル酸及び/またはメタクリル酸の0.3〜0.75当量を反応させてなるエポキシ部分エステル化物を得る際に、付加反応触媒として3級アミンまたはその塩をエポキシ基1当量に対し0.0005〜0.005モルの範囲内で、および重合禁止剤としてフェノチアジンをエポキシ部分エステル化物中に占める割合で、0.005〜0.1質量%の範囲内でそれぞれ用いてなるエポキシ部分エステル化物の製造方法である。
【0008】
【発明の実施の形態】
以下、本発明のエポキシ部分エステル化物の製造方法に関し、詳細に説明する。
本発明のエポキシ部分エステル化物とは、以下のエポキシ樹脂のエポキシ基1当量に対してアクリル酸及び/またはメタクリル酸の0.3〜0.75当量を反応させてなるエポキシ部分エステル化物である。よって該エポキシ部分エステル化物とは官能基としてエポキシ基とアクリレート基および/またはメタクリレート基をそれぞれ含有するものを指す。
【0009】
該エポキシ樹脂としては、既に公知の物質から選択されて良く、特に制約はない。そのエポキシ樹脂としては、例えば、以下の化合物が挙げられる。
【0010】

【0017】
エポキシ化ポリブタジエン、エポキシ化ポリイソプレン等のエポキシ化ジエン重合体、3,4ーエポキシー6ーメチルシクロヘキシルメチルー3,4ーエポキシー6ーメチルシクロヘキサンカーボネート、ビス(2,3ーエポキシシクロペンチル)エーテル等が具体的な例として挙げられる。これらエポキシ樹脂は、分子蒸留法等により高純度化を行なっているものを使用することがより好ましい。
【0018】
本発明で用いられるアクリル酸及び/またはメタアクリル酸には特に限定はなく、市販の物をそのまま用いて良い。アクリル酸及び/またはメタアクリル酸の使用割合は、エポキシ樹脂のエポキシ基1当量に対してアクリル酸及び/またはメタクリル酸の0.3〜0.75当量の範囲内で、好ましくは0.4〜0.6当量の範囲内、特に好ましくは0.48〜0.52当量の範囲内で良い。0.3〜0.75当量の範囲内であれば電子分野の塗料用途ならびに接着シール用途に好適に用いることのできるラジカル重合ならびに熱硬化の両方の硬化機能を持つエポキシ部分エステル化物を実質的に合成でき好ましい。
【0019】
また本発明では付加反応触媒としては3級アミン及びまたはその塩の使用が必須要件である。
以下に具体例を挙げて説明する。
【0020】
3級アミンとしては、例えば、ジエタノールアミン、トリエタノールアミン、ジメチルベンジルアミン、トリスジメチルアミノメチルフェノール、トリスジエチルアミノメチルフェノールとそれらの塩類に代表されるものから選択されて良く、特にトリエタノールアミンとすることが好ましい。付加反応触媒としてトリエタノールアミンを選択すると、得られるエポキシ部分エステル化物の貯蔵安定性に富むことは勿論の事、製造したエポキシ部分エステル化物から該触媒をイオン交換水による洗浄で容易に除去分離可能であり、高純度化エポキシ部分エステル化物の製造を可能にする意味でも好ましい。前記の付加反応触媒の使用割合は、エポキシ基1当量に対し0.0005〜0.005モルの範囲内で、より好ましくは0.001〜0.003モルの範囲内で用いられる。0.0005〜0.005モルの範囲内の使用により、本発明のエポキシ部分エステル化物が安価に製造できると共に貯蔵安定性が実質確保でき好ましい。
【0021】
また本発明のエポキシ部分エステル化物の製造方法では、反応系中に重合禁止剤を含有させることが肝要である。エポキシ樹脂とアクリル酸及び/またはメタクリル酸との付加反応系中には原料由来の既に公知の重合禁止剤とフェノチアジンとを併用して良く、肝要なことは、該反応系中または反応生成物中にはフェノチアジンの必要量を含有させることである。
【0022】
公知の重合禁止剤としては、例えば、ハイドロキノン、メチルハイドロキノン、エチルハイドロキノン、t−ブチルハイドロキノン、ハイドロキノンメチルエーテル、ハイドロキノンエチルエーテル、ジ−t−ブチル−p−クレゾール、カテコール、t−ブチルカテコールなどに代表される多価フェノール化合物に代表される。すなわち、アクリル酸及び/またはメタクリル酸原料由来の重合禁止剤の存在は何ら問題ない。
【0023】
該反応系または反応生成物中へのフェノチアジンの必要量とは、エポキシ部分エステル化物中に占める割合で、0.005〜0.1質量%の範囲内、好ましくは0.01〜0.05質量%の範囲内で用いる。0.005〜0.1質量%の範囲内であれば得られるエポキシ部分エステル化物の貯蔵安定性が実質確保できる。
【0024】
また、本発明のエポキシ部分エステル化物の製造方法では、水溶性の金属不活剤をエポキシ部分エステル化物中に占める割合で、0.001〜0.1質量%の範囲内で、好ましくは0.001〜0.01質量%の範囲内で用いる事がより好ましい。0.001〜0.1質量%の範囲内で用いることで合成装置ならびに原料由来で含有することがある極微量不純物、すなわち、鉄、銅、ニッケル、錫、鉛等に代表される遷移金属イオン物質のレドックス硬化活性を実質抑制でき好ましい。水溶性の金属不活剤としては、エチレンジアミン四酢酸、エチレンジアミン四酢酸二ナトリウム塩、エチレンジアミン四酢酸四ナトリウム塩、ニトリロトリ酢酸ナトリウム塩などに代表され、特にエチレンジアミン四酢酸二ナトリウム塩とすることが好ましい。
【0025】
また本発明のエポキシ部分エステル化物の製造方法では、一般的には、付加反応温度条件として80〜135℃の範囲、好ましくは100〜120℃の範囲で実施される。その際、反応系中に空気を吹き込んだ状態下で行うことが好ましい。また気相重合防止の観点で、該付加反応場はエポキシ樹脂に対して良溶解性を示す還流溶剤存在下や紫外線が遮光された反応器中等で実施されて良い。溶剤存在下の反応では反応終了後に脱溶剤工程を加えることが好ましい。還流溶剤としては、一般的に、例えばベンセン、トルエン、キシレンなどが例示できる。
【0026】
また本発明のエポキシ部分エステル化物の製造方法で得たエポキシ部分エステル化物は、使用される用途に応じて、イオン交換法などで得た超純水で洗浄するなどの高純度化精製するなどの後処理工程によっても何ら制約を受けることなく安定して使用できる。
【0027】
また本発明のエポキシ部分エステル化物の製造方法で得たエポキシ部分エステル化物は、貯蔵安定性に優れると共に、一分子中にほぼ理論量のエポキシ基とメタクリレート基及び/またはアクリレート基を有することから光硬化ならびに熱硬化の両方の硬化形式で硬化させて使用される用途に好適である。該用途としては塗料分野、接着剤分野、電子部品封止分野が挙げられる。

[Industrial applications]
The present invention relates to a method for producing a partially esterified epoxy product. More particularly, the present invention relates to a method for producing an epoxy partial esterified product, which has excellent storage stability and can be suitably used for liquid crystal sealing.
[0002]
[Prior art]
Conventionally, a method for producing a polyhydric acrylate or polyhydric methacrylate derived from a bisphenol A type epoxy resin and acrylic acid or methacrylic acid is known. For example, Japanese Patent No. 2593019 uses a trivalent phosphorus compound as a catalyst. Although a method for producing an epoxy ester is known, a method has been proposed in which after the synthesis of the epoxy ester, a trivalent catalyst is oxidized to inactivate the catalyst to impart storage stability. However, the production method has a problem that a catalyst deactivation treatment is essential. Further, Japanese Patent Application Laid-Open No. 11-21333 proposes a method for producing an epoxy ester using an organic sulfur compound as a catalyst. According to this method, an epoxy ester in which an epoxy group and a carboxyl group coexist stably at the synthesis stage and storage stability is dramatically improved can be produced.
However, there is no known method for producing a partially esterified epoxy compound having excellent storage stability in which the synthesized product contains an epoxy group and an acrylate group and / or a methacrylate group at a high concentration. (Patent Documents 1 and 2)
