稳定的水性聚氨酯 - 聚脲分散体

Stabilized aqueous polyurethane-polyurea dispersions
摘要：
The present invention relates to a binder composition containing A) at least one aqueous polyurethane-polyurea dispersion and B) at least one stabilizer containing a) at least one amine having a structural unit corresponding to formula (I)  which has no hydrazide groups, b) at least one compound having a structural unit corresponding to formula (II) —CO—NH—NH—  (II)  and c) optionally a stabilizing compound other than a) and b). The polyurethane dispersions are manufactured in the presence of components a) and b). It is possible for components a) and b), depending on the grade used, to be incorporated into the polymer framework as structural units.For this reason binder compositions comprising A) at least one aqueous polyurethane dispersion, containing structural units of at least one stabilizing agent or mixture of stabilizing agents B) based on a) at least one amine with the general formula (I),  which has no hydrazide groups, b) at least one compound with the general formula (II), —CO—NH—NH—  (II)  and c) optionally a stabilizing compound other than a) and b). are also the subject matter of the invention in question. The present invention also relates to a process for the preparation of these binder compositions.Further, the present invention relates to coating, adhesive and sizing compositions containing the binder compositions according to the invention.Finally, the present invention also relates to glass fibers sized with sizing compositions containing the binder compositions according to the invention.
摘要（中）：

本发明涉及含有A）至少一种水性聚氨酯 - 聚脲分散体的粘合剂组合物，以及B）至少一种稳定剂，其含有a）至少一种具有对应于没有酰肼基团的式（I）结构单元的胺，b ）至少一种具有对应于式（II）的结构单元的化合物<？in-line-formula description =“In-Line Formulas”end =“lead”→> CO-NH-NH-（II） -line-formula description =“In-line Formulas”end =“tail”？>和c）任选的a）和b）以外的稳定化合物。 在组分a）和b）存在下制备聚氨酯分散体。 组分a）和b）可能取决于所用的等级作为结构单元并入聚合物框架中。 为此，粘合剂组合物包含：A）至少一种包含至少一种稳定剂或稳定剂混合物的结构单元的水性聚氨酯分散体，B）基于a）至少一种具有通式（I）的胺，其不具有 酰肼基团，b）至少一种具有通式（II）的化合物，<？in-line-formula description =“In-line Formulas”end =“lead”→CO-NH-NH-（II） ？in-line-formula description =“In-line Formulas”end =“tail”？>和c）任选的a）和b）以外的稳定化合物。 也是本发明的主题。 本发明还涉及制备这些粘合剂组合物的方法。 此外，本发明涉及包含根据本发明的粘合剂组合物的涂料，粘合剂和施胶组合物。 最后，本发明还涉及用含有本发明的粘合剂组合物的施胶组合物定尺寸的玻璃纤维。
