Description
7つのプレポリマーを合成し、典型的な一液型PU接着製剤中で評価した。
ラボリアクター中でポリオール(1)、ポリオール(2)及び可塑剤を混合する。真空下で混合物を攪拌し、120℃まで加熱する。物質の温度が120℃に達したら、真空下で50℃まで冷却する。次いで、イソシアナートを添加し、混合物を窒素雰囲気下で5分間攪拌する。触媒を添加し、混合物を30分間反応させ、次いで、イソシアナート含有量を測定する。イソシアナート含有量が(過剰量のジブチルアミンを添加し、1NのHClを用いて逆滴定を行うことにより)推定値の0.25%未満から0.1%超までである場合、真空を設定し、さらに20分間混合物を混合させる。表3はプレポリマー中のウレタン及び尿素単位(ハードセグメント)の含有量を表す。列H及び列Lは、参照プレポリマー製剤と発明プレポリマー製剤の間の差異は主に総尿素及びウレタンハードセグメントの量にあることを示す。
表4は、製剤化した接着剤の製剤設計の詳細を示す。プレポリマーは基本粘性が低いため、プレポリマーD、E及びFを使用する接着製剤は可塑剤を必要としない。
プレポリマー、カーボンブラック、焼成シリカ、未コーティングカオリン、コーティング済カオリン、可塑剤、及びイソシアナートを遊星型ミキサーに入れ、窒素雰囲気下、30℃で10分間混合する。次いで真空に設定し、混合物をさらに30分、30℃で混合する。混合物が均一になったら、触媒(1)及び触媒(2)を混合物に添加し、10分間、窒素雰囲気下、30℃で混合する。次いで真空に設定し、混合物をさらに20分間混合する。
適用された方法
DIN 53504に準じた引張強度、引張弾性係数、引張伸び。
DIN ISO 34−1に準じた引裂抵抗。
DIN EN 1465に準じた実験せん断強度:基板:電着スチール、接着面積:10*25mm、接着層の厚さ:2mm
表5は、プレポリマー自体の試験データを示す。MDIよりもHDIを使用したプレポリマーは他の製剤と比較して有意な粘性の低下を示し、ゆえに、当該プレポリマーは、当該プレポリマーまたは接着性剤のいずれかに対し可塑剤を加えることなく使用することができる。
表6は、調製された接着性剤の試験データを示す。以下を結論づけることができる:
・全ての発明製剤は、20MPaを超える弾性係数を満たす。
・発明製剤は、高い弾性係数と、200%を超える高いバルク伸長を兼ね備えている。
・30MPaを超える最も高い弾性係数は、芳香族(たとえばMDI)ジイソシアナートよりも脂肪族(たとえばHDI)ジイソシアナートを使用することにより得られる。
・PPOよりもPTMEGをベースとしたポリエーテルポリオールを使用することにより、バルク伸長及び引裂強度はさらに有意に増加される。
・純粋にPPOをベースとしたプレポリマーは、弾性係数要求を満たさない。
・発明製剤は、凝集破壊様式と併せて高い重ねせん断強度を示す。
