Description
プラスチック機能性高分子材料事典 426頁 産業調査会 事典出版センター 2004年
プレポリマー温度:約70〜80℃
発泡剤温度:約50〜60℃
金型温度:約50〜60℃
離型時間:約15〜20分間
二次架橋:120℃、24時間
成形は、成形密度0.5g/cm3のシート形状および自動車サスペンション用補助スプリング形状の評価用サンプルとして成形され、シート形状への成形は、30×60×150mmに成形されたブロックを二次加硫後に30×60×2mmスライスすることにより行われた。
数平均分子量Mn 2,000、水酸基価56のエチレンアジペート系ポリエステルポリオール100重量部を120℃で溶融させた後、予め120℃に熱した反応器に仕込み、撹拌しながらTODI 40重量部を加えて30分間反応させ、ウレタンプレポリマーを得た。また、60℃で溶融させた数平均分子量Mn 2,000、水酸基価56のエチレンアジペート系ポリエステルポリオール3937重量部に、水150重量部、1,4-ブタンジオール150重量部、整泡剤100重量部、アミン系触媒10重量部を加え、これらを2時間撹拌混合して発泡剤を得た。
実施例1において、発泡剤成分中、1,4-ブタンジオールの代わりにトリメチロールプロパン149重量部が用いられた。
数平均分子量Mn 2,000、水酸基価67のエチレンアジペート系ポリエステルポリオール100重量部を120℃で溶融させた後、予め120℃に熱した反応器に仕込み、撹拌しながらTODI 40重量部を加えて30分間反応させ、ウレタンプレポリマーを得た。また、60℃で溶融させた数平均分子量Mn 2,000、水酸基価56のエチレンアジペート系ポリエステルポリオール4436重量部に、水150重量部、1,4-ブタンジオール150重量部、整泡剤100重量部、アミン系触媒10重量部を加え、これらを2時間撹拌混合して発泡剤を得た。
実施例1において、TODI量を30重量部に変更し、またエチレンアジペート系ポリエステルポリオールを用いずに、他の各成分をそれぞれ同量用いて発泡剤が調製された。
比較例1において、発泡剤成分中、1,4-ブタンジオールの代わりにトリメチロールプロパン149重量部が用いられた。
実施例1において、TODIの代わりにMDI 45重量部を用いたウレタンプレポリマーが、またエチレンアジペート系ポリエステルポリオール量が2480重量部に、アミン系触媒量が8重量部にそれぞれ変更された発泡剤が用いられた。
数平均分子量Mn 2,000、水酸基価56のエチレンアジペート系ポリエステルポリオール100重量部を120℃で溶融させた後、予め120℃に熱した反応器に仕込み、撹拌しながらNDI 20重量部を加えて30分間反応させてウレタンプレポリマーを得た。また、水150重量部、1,4-ブタンジオール150重量部、整泡剤100重量部、アミン系触媒2重量部を2時間撹拌混合し、発泡剤を得た。
硬さ:スプリング式アスカーC型
引張強さ、破断時伸び:JIS K6261準拠(サンプル形状:ダンベル状3号形)
圧縮永久歪:JIS K6262準拠(13mm径、2mm厚シート3枚重ね、25%圧縮、80℃×70時間)
補助スプリング耐久性:10kN×1Hz×10万回圧縮後の亀裂有無で評価
亀裂が発生したものについては亀裂発生時の圧縮回数で評価
