Description
イソシアネート成分は、少なくとも1種のポリイソシアネートと、ポリエステルポリオール、ポリエーテルポリオール、及びそれらの組み合わせからなる群から選択される少なくとも1種のポリオールと、イソシアネート基(すなわち、R−N=C=O)と反応する2つ以上のOH基を有し、かつO=C−O−、O=C−C−O−、O=C−C=C−O−、またはそれらのプロトン化形態から選択される水素架橋基を含有する少なくとも1種のポリオールと、を含む反応物質(「プレポリマー反応物質」)の反応生成物である少なくとも1種のイソシアネートプレポリマーを含む。プレポリマー反応物質の各々を以下に詳細に論述する。
無溶剤接着剤組成物は、ポリエステルポリオール、ポリエーテルポリオール、及びそれらの組み合わせからなる群から選択される少なくとも1種のポリオールを含むポリオール成分を更に含む。ポリオール成分は、任意選択的に、2つ以上のOH基及び水素架橋基を有するポリオール、接着促進剤、及びジオールまたはトリオールモノマーを含み得る。
実施例を調製するために使用された原料は、以下の表1において商品名及び供給者によって特定されている。
実施例の接着剤組成物から調製されたラミネートを結合強度試験に供する。Instron Corporationから入手可能な5940シリーズ単一カラムテーブルトップシステムを使用して、250mm/分のクロスヘッド速度下でのT−剥離試験のためにラミネートを15mm幅のストリップに切断する。試験中、各ストリップの尾部を手でわずかに引っ張って、尾部が剥離方向に対して90°の角度を保つようにする。3つのストリップを各サンプルについて試験し、平均値を計算する。結果はN/15mm単位である。比較的高い値は、より良好な結合強度を示す。
