(JA) 水性ポリウレタン樹脂分散体及びそれを含有するコーティング用組成物
Abstract:
(EN) The invention provides an aqueous polyurethane resin dispersion wherein a polyurethane resin obtained by reacting (A) a polyurethane prepolymer, which is obtained by reacting (a) a polyisocyanate compound, (b) a polyol compound containing a polycarbonate polyol having a number-average molecular weight of 800 to 3,500, and (c) an acidic group-containing polyol compound, and (B) a chain extender is dispersed in an aqueous medium; the chain extender (B) contains a polyamine compound having a total of three or more amino groups and/or imino groups per molecule; and the polyurethane resin has a urethane bond content of 5 - 10 wt% by solid content, a urea bond content of 2 - 7 wt% by solid content, and a carbonate bond content of 15 to 40 wt% by solid content, but does not contain ether bonds or ester bonds, has a crosslinking point density of 1.0×10-4~1.0×10-3 mol/g, has an acid value of 12 to 20 mg KOH/g, and has a weight-average molecular weight of 100,000 or greater.
(FR) Selon l'invention, dans un milieu aqueux, est dispersée une résine polyuréthane obtenue par réaction : (A) d'un prépolymère de polyuréthane obtenu par réaction (a) d'un composé polyisocyanate, (b) d'un composé polyol contenant un polycarbonate-polyol de masse moléculaire moyenne en nombre comprise entre 800 et 3500 et (c) d'un composé polyol comprenant un groupe acide; et (B) d'un agent d'extension de chaîne. Ledit (B) agent d'extension de chaîne comprend un composé polyamine qui possède au total dans chaque molécule au moins trois groupes amino et/ou groupes imino. Ladite résine polyuréthane présente, pour chacune selon la norme de teneur en matières solides, une teneur en liaisons uréthane de 5 à 10% en masse, une teneur en liaison urée de 2 à 7% en masse, une teneur en liaison carbonate de 15 à 40% en masse, une densité de point de réticulation de 1,0x10-4 à 1,0x10-3 moles/g sans liaison éther ni liaison ester, un indice d'acidité de 12 à 20mgKOH/g, et une masse moléculaire moyenne en poids d'au moins 100000.
(JA)  本発明は、(a)ポリイソシアネート化合物、(b)数平均分子量が800~3500であるポリカーボネートポリオールを含むポリオール化合物、並びに(c)酸性基含有ポリオール化合物を反応させて得られる(A)ポリウレタンプレポリマーと、(B)鎖延長剤とを反応させて得られるポリウレタン樹脂が、水系媒体中に分散されており、前記(B)鎖延長剤が、1分子中にアミノ基及び/又はイミノ基を合計で3つ以上有するポリアミン化合物を含有し、前記ポリウレタン樹脂は、それぞれ固形分基準で、ウレタン結合の含有割合が5~10重量%であり、ウレア結合の含有割合が2~7重量%であり、カーボネート結合の含有割合が15~40重量%であり、エーテル結合及びエステル結合を有さず、架橋点密度が1.0×10-4~1.0×10-3モル/gであり、酸価が12~20mgKOH/gであり、かつ重量平均分子量が100,000以上である、水性ポリウレタン樹脂分散体を提供する。
