Description
図1に示すニーダーを用い、上記実施の形態と同様にして、上記粉状材料および液状材料から、エポキシ樹脂組成物を製造した。このとき、低温維持手段による設定温度を25℃、加熱手段による設定温度を150℃、冷却手段による設定温度を80℃とした。また、粉体供給手段からの上記粉状材料の供給量を、1時間あたり25kg(精度±3.0%)に設定した。さらに、加圧注入手段からの上記液状材料の供給量を、1時間あたり1678g(精度±1.5%)、その注入圧力を0.2MPa(精度0.1〜0.5MPa)に設定した。
上記実施例において、液状材料の供給口を、第1供給口と同じ上流位置に移動した。それ以外は、上記実施例と同様とした。
上記実施例において、液状材料の供給口を、第1供給口と第2供給口との間の上流位置に移動した。それ以外は、上記実施例と同様とした。
上記実施例において、液状材料の供給口を、冷却手段に対応する下流位置に移動した。それ以外は、上記実施例と同様とした。
上記実施例において、加圧することなく、液状材料を第2供給口から供給した。それ以外は、上記実施例と同様とした。
上記比較例1において、加圧することなく、液状材料を供給した。それ以外は、上記比較例1と同様とした。
上記実施例および比較例1〜5で製造されたエポキシ樹脂組成物の状態を目視にて検査した。その結果、実施例では、灰分ずれのない高品質のものが得られた。それに対し、比較例1では、液状材料の供給口が第1供給口と同じ上流位置であるため、加圧供給した液状材料の圧力が、第1供給口から逃げ、充分に混練できなかった。比較例2では、粉状材料が溶融されない状態で液状材料が供給されたため、スラリー状になった。比較例3では、粉状材料の溶融物が冷却された状態で液状材料が供給されたため、充分に均一に混合することができなかった。比較例4では、液状材料を加圧することなく供給したため、液状材料がニーダー内の圧力に押されて逆流し、粉状材料の溶融物と液状材料とが混練できなかった。比較例5では、液状材料の供給口が第1供給口と同じ上流位置であり、液状材料が、粉状材料と充分に混ざらず、ニーダー内に溜まり、灰分ずれが起こった。

Claims (3)
- 第1供給口とそれよりも下流側の第2供給口とを有するニーダーを用い、粉状材料と液状材料とから光半導体用樹脂組成物を製造する方法であって、上記第1供給口からニーダー内に上記粉状材料を供給し、そのニーダーにより、上記粉状材料を溶融させない温度で、その粉状材料を上記第2供給口側に送り込む工程と、加熱により、上記粉状材料を溶融させるとともに、上記第2供給口から上記液状材料を、ニーダー内の圧力よりも高い圧力で供給し、上記粉状材料の溶融物と、上記液状材料とを混練する工程と、その混練物を、冷却しながらさらに混練する工程とを備えることを特徴とする光半導体用樹脂組成物の製法。
- 上記液状材料が、硬化剤であり、上記粉状材料が、エポキシ樹脂,充填材,酸化防止剤,および硬化促進剤である請求項1記載の光半導体用樹脂組成物の製法。
- 上記粉状材料を溶融させない温度が、5〜50℃の範囲内に設定され、上記粉状材料を溶融させる加熱温度が、100〜170℃の範囲内に設定され、上記混練物を冷却する温度が、20〜85℃の範囲内に設定される請求項2記載の光半導体用樹脂組成物の製法。
