Description
1)1種以上のケトンの存在下に、少なくとも1種のポリオールと、少なくとも1種の第三級アミン中和ポリヒドロキシカルボン酸と、少なくとも1種のポリイソシアネートとを反応させることによる、1.5〜3wt.%(重量%)、特に1.7〜2.5重量%の遊離イソシアネート基含有率を有する、カルボキシレート官能性の、ゲル化していない、水分散性のポリウレタンプレポリマーを製造する工程と、
2)ポリウレタンプレポリマーのケトン溶液を、水と混合することによって水性分散体へ変換する工程と、
3)ポリウレタンプレポリマーの遊離イソシアネート基を水と、および/またはイソシアネート基に付加してウレア基を形成することができる少なくとも2個のアミノ基を有する少なくとも1種の化合物と反応させることによって、ポリウレタンプレポリマーを鎖延長させる工程と
を含む、樹脂固形分1gあたり10〜50mgKOHのカルボキシル価および樹脂固形分に対して5〜10重量%のケトン含有率を有する水性ポリウレタンウレア樹脂分散体の製造方法であって、
工程3)の完了後に得られる水性ポリウレタンウレア樹脂分散体が、樹脂固形分に対して5〜10重量%のケトンを含有するような方法で、工程1)に使用されるケトンの割合が選択される方法を提供する。
112mgのKOH/gのヒドロキシル価を有する24.08pbw(重量部)のポリエステルジオール(ヘキサンジオールおよびアジピン酸とイソフタル酸との2:1モル混合物から製造された)と1.32pbwのジメチロールプロピオン酸とを、攪拌機および還流冷却器を備え付けた反応容器中で11.6pbwのアセトンと混合した。ポリエステルジオールに対して0.004重量%のジブチルスズジラウレート触媒を添加した。混合物を50℃に加熱した後、9.45pbwのイソホロンジイソシアネートを加え、混合物を、一定のNCO値が得られるまで50℃で撹拌した。次に0.88pbwのジメチルイソプロピルアミンを加え、混合物を均一になるまで50℃で撹拌した。次に54.79pbwの脱イオン水を加えて水性分散体を形成し、その後6.48pbwのエチレンジアミンの6.25重量%水溶液を40℃で加えた。次に温度を50℃に上げて元に戻し、この温度を2時間維持した。次に還流冷却器を蒸留ブリッジで置き換え、アセトンを蒸留によって除去して3重量%の残留アセトン含有率まで下げた。蒸留中に同伴したいかなる水も、得られたポリウレタンウレア樹脂分散体中で35重量%の樹脂固形分含有率を達成することによって補った。
24.08pbwの比較例1に使用したポリエステルジオールと1.32pbwのジメチロールプロピオン酸とを、攪拌機および還流冷却器を備え付けた反応容器中で3pbwのアセトンと混合した。ポリエステルジオールに対して0.004重量%のジブチルスズジラウレート触媒を添加した。混合物を50℃に加熱した後、9.45pbwのイソホロンジイソシアネートを加え、混合物を50℃で撹拌した。反応中に粘度の大幅な増加があり、反応容器の内容物の撹拌はもはや可能ではなかった。それ故、合成を終了させた。
24.08pbwの比較例1に使用したポリエステルジオールと、1.32pbwのジメチロールプロピオン酸と0.88pbwのジメチルイソプロピルアミンとを、攪拌機および還流冷却器を備え付けた反応容器中で3pbwのアセトンと混合した。ポリエステルジオールに対して0.004重量%のジブチルスズジラウレート触媒を添加した。混合物を50℃に加熱した後、9.45pbwのイソホロンジイソシアネートを加え、混合物を、一定のNCO値が得られるまで50℃で撹拌した。次に54.79pbwの脱イオン水を加えて水性分散体を形成し、その後6.48pbwのエチレンジアミンの6.25重量%水溶液を40℃で加えた。次に温度を50℃に上げて元に戻し、この温度を2時間維持した。冷却後に35重量%樹脂固形分の水性ポリウレタンウレア樹脂分散体を得た。
24.08pbwの比較例1に使用したポリエステルジオールと、1.32pbwのジメチロールプロピオン酸と0.88pbwのジメチルイソプロピルアミンとを、攪拌機および還流冷却器を備え付けた反応容器中で3pbwのアセトンと混合した。ポリエステルジオールに対して0.004重量%のジブチルスズジラウレート触媒を添加した。混合物を50℃に加熱した後、9.45pbwのイソホロンジイソシアネートを加え、混合物を、一定のNCO値が得られるまで50℃で撹拌した。NCO基を脱官能基化するためにNCOに対して10%モル過剰のジブチルアミンを加えた。
