摘要：

Waterborne polyurethane (WPU) with different macromolecular diols as soft segments was synthesized by the acetone dilution method. Fourier transform infrared (FTIR) spectroscopy, particle size and distribution (PSD) and transmission electron microscopy (TEM) test measurements were utilized to characterize the structure. The effect of the structure on performance was determined by the solids content, rheological and thixotropic behavior tests, water absorption tests and adhesion tests. It was found that with different macromolecular diols as a soft segment polyurethane has low water absorption, high energy storage, good shear resistance and adhesion. The minimum water absorption value was 6.02%.
