摘要
在合成聚氨酯时分别使用聚醚二醇和聚酯二醇,所得产物各具优缺点。因两者结构、极性、相容性和反应活性差异较大,很难将它们简单复合使用。文中简述了性能相异的两类二醇制备性能互补的聚氨酯的情况。分别从两类二醇复合制备聚氨酯的合成方法、性能及其发展历程方面重点介绍聚醚/聚酯型水性聚氨酯的近期发展。
The polyether diol and polyester diol are used separately in production of polyurethane, the obtained products possess their advantages and disadvantages. Because there are large differences of the structure, polarity, compatibility and reaction activity between them, it is very difficult to use them by simple combination. Currently the breakthrough for preparing polyurethane by combining two kinds of diols is simply introduced. It is possible to prepare polyurethane with complementary performance by using two kinds of diols with different performance. The recent developments of polyether/polyester type waterborne polyurethanes are emphatically introduced from aspects of preparation methods, performance and its development course of polyurethane prepared by combining two kinds of diols.
