摘　　要：水性聚氨酯(WPU)是一种环境友好型高分子材料,广泛用于纺织、皮革、造纸和家具等行业;目前国内的WPU产品其固含量普遍较低,增加固含量可提高反应设备的空间利用率,降低产品运输成本和单位产品能耗,便于实现WPU的大规模生产和产品性能提高。介绍了聚合物乳液固含量的极限理论和近5年来高固低黏WPU的研究进展,并对其在纺织上的应用进行了展望。Waterborne polyurethane （WPU） is an environmentally friendly polymer material which has been widely used in textile, leather, paper and furniture. At present, the solid content of WPU products is generally less than 40 wt% in domestic. The space utilization of reaction equipment could be improved and the transportation cost and energy consumption per unit product could be reduced through the increasing of the solid content of WPU products, facilitating the realization of WPU production and the performance improvement of the products. Herein, the limit theory of the solid content of polymer latexes was introduced and the research progress on the synthesis of high solid content WPU with low viscosity in recent five years was outlined in detail. The application of these WPU in textile and its prospection were proposed.
