(5)水性聚氨酯胶粘剂可与多种水性树脂混合,以改进性能或降低成本。此时应注意离子型水性胶的离子性质和酸碱性,否则可能引起凝聚。因受到聚合物间的相容性或在某些溶剂中的溶解性的影响,溶剂型聚氨酯胶粘剂只能与为数有限的其他树脂胶粘剂共混。

一般来说,水性聚氨酯的固态强度比溶剂型聚氨酯制品的强度差,但通过原料、配方、工艺的选择,能使水性聚氨酯的性能与溶剂型相媲美。

聚氨酯双二脲离聚物具有足够的亲水性,加酸的稀水溶液形成均相溶液,再与甲醛水溶液反应进行羟甲化,含羟基的聚氨酯严能在50—130℃用无限水稀释,形成稳定乳液。当降低体系的pu值时,能在分散相中进行缩聚反应,形成高分子量聚氨酯。含离子基团的端NCO预聚体形成端脲基或二基聚氨酯低聚物后,则直接在熔融状态乳化于水,再加甲醛水溶液进行羟基化及扩链反应。
