包含聚氨酯的水分散体及其在生产片状基材中的用途
摘要：
本发明涉及包含如下组分的水分散体：(A)至少一种聚氨酯，(B)至少一种通式(Ia)或(Ib)的化合物，其中R1、R2和R3可以相同或不同且选自A1-NCO和A1-NH-CO-X，其中A1为具有2-20个碳原子的间隔基，和X选自O(AO)xR4，AO为C2-C4氧化烯，x为1-50的整数，和R4选自氢和C1-C30烷基，以及(C)至少一种具有反应性基团的聚硅氧烷化合物。
摘要（英）：

The invention relates to aqueous dispersions comprising (A) at least one polyurethane, (B) at least one compound of the general formula (Ia) or (Ib) in which R<1>, R<2> and R<3> may be identical or different and are selected from A<1>-NCO and A<1>-NH-CO-X, in which A<1> is a spacer having 2 to 20 carbon atoms and X is selected from O(AO)xR<4>, AO is C2-C4-alkylene oxide, x is an integer in the range from 1 to 50 and R<4> is selected from hydrogen and C1-C30-alkyl, (C) and at least one silicone compound having reactive groups.
