摘　　要：将不同类型填料加入水性聚氨酯中,用机械发泡法制备水性聚氨酯发泡浆料;涂覆在无纺布上,经烘干制备出水性聚氨酯合成革贝斯。以涂层厚度保持率、泡孔结构、表观性能、贝斯物理机械性能和卫生性能等为指标,考察了不同填料对贝斯性能的影响。试验结果表明:添加填料能增加水性贝斯涂层厚度保持率;木质素(NA)可增加涂层柔软度、提高水性贝斯的卫生性能;轻质CaCO3对水性聚氨酯涂层有补强效果。Waterborne polyurethane foam slurry was prepared by adding different paddings into waterborne polyurethane via mechanical foaming method. The preparation of waterborne polyurethane synthetic leather base was dried by scraping the foaming pulp to non - woven fabrics. The influence of different types of padding on waterborne polyurethane synthetic leather base were in- vestigated by taking the thickness variation, foam structure, apparent performance, mechanical properties, water vapor ty as.the indexes. proves after adding by adding xylogen（ permeabili- The results of experiment show that thickness variation of waterborne polyurethane synthetic leather base im- padding.
