摘 要:传统水性聚氨酯(WPU)因固含量偏低导致干燥能耗高、成膜效率低。尽管现有研究 通过超支化、低温扩链等策略实现了固含量提升,但两步乳化混合法工艺繁琐,且未根本解决 离子基团分布不均引起的黏度激增难题。因此提出将亲水磺酸根基团引入聚氨酯软段,通过 离子基团在分子链中的相对均匀分布,一步法直接合成高固低黏 WPU 乳液,其最高固含量可 达 70%,稀释后乳液性能保持稳定。

Abstract:Conventional water-based polyurethanes (WPUs) suffer from high drying energy consumption and low film-forming efficiency due to their low solids content. Although existing studies have achieved higher solids content through strategies such as hyperbranching and lowtemperature chain extension, the two-step emulsion blending process is cumbersome and has not fundamentally resolved the problem of viscosity spikes caused by uneven distribution of ionic groups. This study proposes introducing hydrophilic sulfonic acid groups into the polyure⁃ thane soft segment. By ensuring a relatively uniform distribution of ionic groups along the molecular chain, a one-step method is employed to directly synthesize high-solids, lowviscosity WPU emulsions. The maximum solids content reaches 70%, and the emulsion prop⁃ erties remain stable after dilution.
Key words:ionic soft segment; high solid content; waterborne polyurethane; emulsion; sulfo⁃ nated polyols
