Description
本出願は、2017年12月27日に出願されたイタリア特許出願第102017000149966号の利益を主張する。
接着剤組成物は、多種多様な目的に有用である。例えば、接着剤組成物は、ポリエチレン、ポリプロピレン、ポリエステル、ポリアミド、金属、メタライズ、紙、またはセロハンなどの基材を一緒に接合させて、複合フィルム、すなわち、積層体を形成するために使用される。異なる最終使用用途における接着剤の使用は一般に知られている。例えば、接着剤は、包装産業において、特に食品包装のために使用されるフィルム/フィルムおよびフィルム/ホイル積層体の製造に使用することができる。積層用途で使用される接着剤、すなわち「積層接着剤」は、一般に、溶剤ベース、水ベース、および無溶剤の3つのカテゴリーに分類することができる。接着剤の性能は、カテゴリーによって、また接着剤が塗布される用途によって変わる。
いくつかの実施形態では、イソシアネート成分は、一緒にブレンドされた2種以上のイソシアネートを含むイソシアネートブレンドを含む。イソシアネートは、イソシアネートプレポリマー、イソシアネートモノマー、ポリイソシアネート(例えばダイマー、トリマー等)、およびそれらの2つ以上の組み合わせからなる群から選択することができる。本明細書で使用される場合、「ポリイソシアネート」は、2つ以上のイソシアネート基を含有する任意の化合物である。イソシアネートプレポリマーとは、イソシアネートおよびポリオールを含む反応物の反応生成物である。本明細書で使用される場合、「イソシアネートプレポリマー」は、ポリイソシアネート自体であり得る。
いくつかの実施形態では、ポリオール成分は、高反応性アミン開始ポリオールおよびシリコーン系添加剤を含む。
ポリオール成分中にアミン開始ポリオールを含めることによって、既存の二成分無溶剤接着剤組成物に使用される従来のポリオールよりも高い反応性および速い硬化が提供される。アミン開始ポリオールは、第1級ヒドロキシル基および少なくとも1つの第3級アミンを組み込む主鎖を含む。いくつかの実施形態では、ポリオール成分は、非アミン開始ポリオールである別のタイプのポリオールを含むこともできる。各ポリオールタイプは、1種類のポリオールを含み得る。あるいは、各ポリオールタイプは、異なる種類のポリオールの混合物を含み得る。いくつかの実施形態では、一方のポリオールタイプは1種類のポリオールであってもよく、他方のポリオールタイプは異なる種類のポリオールの混合物であってもよい。
いくつかの実施形態では、ポリオール成分は、シリコーン系添加剤をさらに含む。いくつかの実施形態では、シリコーン系添加剤は、消泡剤、または脱泡剤である。いくつかの実施形態では、シリコーン系添加剤は、湿潤剤である。いくつかの実施形態では、ポリオール成分は、消泡剤のみを含む。いくつかの実施形態では、ポリオール成分は、湿潤剤のみを含む。いくつかの実施形態では、ポリオール成分は、消泡剤および湿潤剤の両方を含む。シリコーン系添加剤を含めることによって、濡れ性が向上し、従来の無溶剤積層接着剤で発生する空気の閉じ込めの問題が低減されると考えられる。
いくつかの実施形態では、非アミン開始ポリオールは、任意に、接着剤組成物中、例えばポリオール成分中に含まれ得る。非アミン開始ポリオールの例としては、ポリエステルポリオール、ポリエーテルポリオール、ポリカーボネートポリオール、ポリアクリレートポリオール、ポリカプロラクトンポリオール、ポリオレフィンポリオール、天然油ポリオール、およびこれらの2つ以上の組み合わせが含まれるが、これらに限定されない。好ましくは、非アミン開始ポリオールは、ASTM D2196の方法で測定して、25℃で30~40,000mPa・s、または50~30,000mPa・s、または70~20,000mPa・sの粘度を有する。好ましくは、非アミン開始ポリオールは、ASTM D2196の方法によって測定して、25℃で100~10,000mPa・sの粘度を有する。
開示された無溶剤接着剤組成物のイソシアネート成分およびポリオール成分は、別々に配合され、望ましくは、それがラミネート構造を形成するまで貯蔵されることが企図される。好ましくは、イソシアネート成分およびポリオール成分は、25℃で液体状態である。成分が25℃で固体であっても、必要に応じて成分を加熱して液体状態にすることが可能である。接着剤組成物のポットライフが硬化プロセスから切り離されるので、成分は無期限に保存することができる。
本開示は、開示された接着剤組成物および既存の接着剤組成物を例示する例(例証的実施例「IE」、比較例「CE」、集合的に「実施例」)を説明することによって、ここで、さらに詳細に説明される。しかしながら、本開示の範囲は、当然ながら、実施例に限定されない。
