Description
本出願は、2018年11月16日出願の日本出願第2018-215711号に基づく優先権を主張し、前記日本出願に記載された全ての記載内容を援用するものである。
光ファイバの耐ボイド特性を向上する観点から、フィラーを含有する樹脂組成物を用いてプライマリ樹脂層を形成することで、プライマリ樹脂層の強度を高めることが考えられる。しかしながら、プライマリ樹脂層に用いられる樹脂組成物は、通常、シランカップリング剤を含有していることから、フィラーを添加すると、樹脂組成物が増粘し易く、ポットライフが短くなる傾向にある。
本開示によれば、ポットライフが長い光ファイバ被覆用の樹脂組成物、及び、当該樹脂組成物から形成されるプライマリ樹脂層を備える光ファイバを提供することができる。
最初に、本開示の実施形態の内容を列記して説明する。本開示の一態様に係る樹脂組成物は、ウレタン(メタ)アクリレートオリゴマー、モノマー、光重合開始剤及びシランカップリング剤を含有するベース樹脂と、紫外線硬化性の官能基を有する表面修飾無機酸化物粒子とを含み、表面修飾無機酸化物粒子における表面修飾量が、0.2mg/m2以上である。
本開示の実施形態に係る樹脂組成物及び光ファイバの具体例を、必要により図面を参照しつつ説明する。なお、本発明はこれらの例示に限定されず、請求の範囲によって示され、請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。以下の説明では、図面の説明において同一の要素には同一の符号を付し、重複する説明を省略する。
本実施形態に係る樹脂組成物は、ウレタン(メタ)アクリレートオリゴマー、モノマー、光重合開始剤及びシランカップリング剤を含有するベース樹脂と、紫外線硬化性の官能基を有する表面修飾無機酸化物粒子とを含む。
本実施形態に係る表面修飾無機酸化物粒子は、無機酸化物粒子の表面が紫外線硬化性の官能基を有するシラン化合物により処理され、無機酸化物粒子の表面に紫外線硬化性の官能基が導入されている。すなわち、表面修飾無機酸化物粒子は、無機成分と有機成分とから構成されている。官能基は、アクリロイル基、メタクリロイル基又はビニル基であってもよい。このような官能基を有することで、耐ボイド特性の高い樹脂層を形成し易くなる。
本実施形態に係るベース樹脂は、ウレタン(メタ)アクリレートオリゴマー、モノマー、光重合開始剤及びシランカップリング剤を含有する。
図1は、本実施形態に係る光ファイバの一例を示す概略断面図である。光ファイバ10は、コア11及びクラッド12を含むガラスファイバ13と、ガラスファイバ13の外周に設けられたプライマリ樹脂層14及びセカンダリ樹脂層15を含む被覆樹脂層16とを備えている。
(オリゴマー)
オリゴマーとして、Mn4000のポリプロピレングリコール、イソホロンジイソシアネート、ヒドロキシエチルアクリレート及びメタノールを反応させることにより得られたウレタンアクリレートオリゴマーを準備した。
モノマーとして、ノニルフェノールEO変性アクリレート(東亞合成株式会社の商品名「アロニックスM-113」、n≒4)、N-ビニルカプロラクタム及び1,6-ヘキサンジオールジアクリレートを準備した。
光重合開始剤として、2,4,6-トリメチルベンゾイルジフェニルホスフィンオキシドを準備した。
シランカップリング剤として、3-メルカプトプロピルトリメトキシシランを準備した。
ウレタンアクリレートオリゴマー60質量部、ノニルフェノールEO変性アクリレート22.8質量部、N-ビニルカプロラクタム4.8質量部、1,6-ヘキサンジオールジアクリレート1.6質量部、2,4,6-トリメチルベンゾイルジフェニルホスフィンオキシド2.7質量部及び3-メルカプトプロピルトリメトキシシラン0.8質量部を混合して、ベース樹脂を調製した。
表面修飾無機酸化物粒子として、3-メタクリロキシプロピルトリメトキシシランで表面処理されているシリカ粒子(以下、単に「シリカ粒子」という。)を含むシリカゾル(MEK分散液)を準備した。
未修飾のシリカ粒子を含むシリカゾル(MEK分散液)を準備した。
ベース樹脂と、シリカゾルとを混合した後、MEKの大部分を除去して、樹脂組成物中のシリカ粒子の含有量が10質量%となるように、樹脂組成物を調製した。
樹脂組成物にクロロホルムを加えて遠心分離を行い、沈殿物を回収した。沈殿物にアセトンを加えて遠心分離を行い、上澄みを除去した後、沈殿物に再度アセトンを加えて遠心分離、上澄み除去を行う操作を4回行い、シリカ粒子を取り出した。乳鉢ですりつぶしたシリカ粒子を室温で12時間減圧乾燥して揮発分を除去した。遠心分離は、30000rpmで120分間の条件で行った。乾燥後のシリカ粒子を80℃で12時間減圧処理し、細孔分布測定装置(マイクロメリティクス製の「ASAP-2020」)を用いて、窒素吸着BET法によりシリカ粒子の比表面積(m2/g)を測定した。
表面修飾量(mg/m2)=有機成分の割合/比表面積
スピンコータを用いて、樹脂組成物をポリエチレンテレフタレート(PET)フィルムの上に塗布した後、無電極UVランプシステム(Dバルブ)(ヘレウス製)を用いて、1000±100mJ/cm2の条件で硬化させ、PETフィルム上に厚み200±20μmの樹脂層を形成した。樹脂層をPETフィルムから剥がし、樹脂フィルムを得た。
樹脂組成物を容器に入れて60℃で保管し、樹脂組成物が増粘して塗布できなくなる時期を調べた。
