Description
まず、反応性溶媒としてブチルグリシジルエーテル(ジャパンエポキシレジン社製、商品名:BGE)を用意し、このブチルグリシジルエーテル50質量部に四級アンモニウム塩が層間に挿入されている層状粘土鉱物(コープケミカル社製、商品名:STN)を10質量部添加し、超音波ホモジナイザー(BRANSON社製、商品名:MODEL450)を用いて膨潤させた後、3本ロールミル混合機(井上製作所社製、商品名:S−4 3/4×11)を10回以上通過させて混練した。
上記した実施例1において、3本ロールミル混合機によるせん断応力を加えた混練と混練後の反応性溶媒の減圧除去を行わずに高電圧機器用絶縁材料を作製した。具体的には、まず反応性溶媒としてのブチルグリシジルエーテル(ジャパンエポキシレジン社製、商品名:BGE)10質量部に、四級アンモニウム塩が層間に挿入されている層状粘土鉱物(コープケミカル社製、商品名:STN)を2質量部添加し、超音波ホモジナイザー(BRANSON社製、商品名:MODEL450)を用いて膨潤させた。
上記した実施例1において、四級アンモニウム塩が層間に挿入された層状粘土鉱物に代えて、層間にナトリウムイオンが存在する層状粘土鉱物を用い、これを直接ビスフェノールA型エポキシ樹脂に添加・混合すると共に、シランカップリング剤・γ-グリシドドキシ-プロピルトリメトキシシランを添加せずに絶縁材料を作製した。
上記した実施例1において、反応性溶媒であるブチルグリシジルエーテルに代えてトルエンを用いて層状粘土鉱物を膨潤させると共に、3本ロールミル混合機によるせん断応力を加えた混練およびトルエンの減圧除去を行わずに絶縁材料を作製した。
