Description
(a)ジイソシアネート又はポリイソシアネート
(b)ポリエーテルポリオール又はポリエステルポリオール、及び
(c)任意の発泡剤
を反応させることにより調製される。
実験中に、緯編スペーサーファブリック強化PU複合体の柔軟性、密度、硬度及び機械的特性を測定した。
2.複合体を調製するための手順
表1に示すA成分(スポーツシステム用、A成分を35℃に維持)とB成分を、それぞれ対応する成分を混合して調製した。同時に、型の温度を23℃に維持した。次いで、A成分65gとB成分45gを1つのプラスチックカップに入れ、混合機(EWTHV0,5,タイプ、ヴォルラースミキサー)を用いて7から8秒間混合した。A成分とB成分の混合物62gを型に入れた。次いで、図3の緯編スペーサーファブリックを、生地の頂部層と底部層が型の底面と平行になるように上記混合物内に入れ、生地が型の中間に位置するようにした。その後、型を閉じた。15分後に型を開き、サンプルを取り出し、室温で24時間保持して硬化させ、このように緯編スペーサーファブリック強化PU複合体を得た(図9)。
