一実施形態では10重量%~約50重量%、および別の実施形態では5重量%~約50重量%のVORANOL(商標)CP260;一実施形態では1重量%~約50重量%、および別の実施形態では5重量%~約50重量%のヒマシ油;一実施形態では1重量%~約20重量%、および別の実施形態では5重量%~約20重量%のSIMULSOL TOFPプロピレンオキシド(PO)ポリオール;一実施形態では0重量%~約5重量%、および別の実施形態では1重量%~約5重量%のジプロピレングリコール;一実施形態では1重量%~約60重量%、および別の実施形態では30重量%~約50重量%のSPECFLEX(商標)NS540イソシアネート(2.3官能基を有するポリマーMDI);一実施形態では0重量%~約20重量%、および別の実施形態では0重量%~約10重量%のモレキュラーシーブ;一実施形態では0重量%~約10重量%、および別の実施形態では0重量%~約5重量%の湿潤剤;一実施形態では0重量%~約1重量%、および別の実施形態では0重量%~約0.5重量%の消泡剤;一実施形態では0重量%~約10重量%、および別の実施形態では0重量%~約5重量%の有機溶媒;ならびに一実施形態では0重量%~約1重量%、および別の実施形態では0重量%~約0.5重量%のTechpur Black。上記の成分の範囲は、配合物の100部(g)あたりのものである。
(I)ポリウレタン複合品組成物を提供するステップ
(II)構造材料がポリウレタン複合品組成物で実質的にコーティングされるように、ステップ(I)のポリウレタン複合品組成物を構造材料と接触させるステップ
(III)ステップ(II)のポリウレタン複合品組成物で実質的にコーティングされた構造材料を加熱するステップ。
吸水測定の概略手順
ステップ(1):試験環境の湿度を50%~約60%の湿度に制御する。
ポリオール配合物とイソシアネート配合物は別々に調製される。2つの配合物は完全に混合され、次に、混合物の粘度上昇を、ARES-G2 Rheometer(TA Instrumentsから入手可能)を介して、10/秒のせん断速度で測定することができる。データは10秒ごとに収集される。
配合物系は型に流し込まれ、試験のためにダンベルの形にカットされる。ISO527規格に記載されている手順に従って、引張強度試験を実施する。最大引張強度と弾性率特性は、すべての完全な複合配合試料について測定される。
実験計画法(混合物設計)は、3成分ポリオールブレンド(ヒマシ油、VORANOL CP260、およびSIMULSOL TOFP)をさまざまな比率でブレンドすることによって実施される。図4および5に記載されている状態図などの状態図は、混合物の混和性と混合物の適合性を検査することによって得られる。目視検査で評価された濁りまたは相分離された試料は、適合性がないものとして扱われる(例えば、図6を参照)。BO系のポリオールを試料組成物に添加する前後の状態図を比較する。より互換性のある試料は、試料組成物へのBO系のポリオールを添加した後に得られることが判定される。
反応性評価のすべての試料は、次の一般的な手順を使用して調製した。ポリオールまたはポリオールブレンドを最初に所定の投与量でブレンドし、次にFlackTekスピードミキサーを使用して2,000rpmで2分間混合した。次に、イソシアネート成分をポリオール部に加え、イソシアネートとポリオールとの得られた混合物を、Flack Tekスピードミキサーを使用して、2,000rpmでさらに2分間再び混合した。次に、各試料の粘度を測定した。流動時間は、粘度が2Pa-s(2,000cps)より高い粘度に達する時間として定義される。
