摘　　要：针对水性聚氨酯涂层产品耐水性不佳且成膜性不如溶剂型聚氨酯等问题,通过对水性聚氨酯的筛选以及仿皮涂层面料制备工艺的研究,确定了高耐磨损水性聚氨酯涂层面料的制备工艺。结果表明:当水性聚氨酯乳液SX9283E与L-2511复配比例(质量分数)为1∶3时,水性聚氨酯仿皮涂层面料表面磨损程度相对较低。水性聚氨酯仿皮涂层工艺配方为颜料质量分数2%~4%、增稠剂1.0%、交联剂3%、流平剂0.2%,转移温度120℃、转移时间20 s。所获得涂层膜10%模量为0.26 MPa、断裂强力为6.58 MPa、断裂伸长率为842.51%,仿皮涂层面料耐干磨损等级为3~4级,耐湿磨损等级为3级,耐干/湿摩擦色牢度可达4~5级。The problems of water-based polyurethane are poor water resistance and inferior film-forming abili⁃ty.The high wear resistance waterborne polyurethane coated fabric is prepared by screening of waterborne polyurethane and studying of the preparation process.The results show that when w(SX-9283E)∶w(L-2511)of waterborne polyurethane lotion is 1∶3,the surface abrasion of the waterborne polyurethane leather-like coat⁃ing fabric is relatively low.The process formula is the mass fraction of pigment of 4%,the thickener of 1.0%,the crosslinking agent of 3%,the slip additive of 0.2%,the transfer temperature of 120℃,and the transfer time of 20 s.The obtained coating film has a 10%modulus of 0.26 MPa,breaking strength of 6.58 MPa,and breaking elongation of 842.52%.The dry wear-resistance level of the imitation leather coating fabric is Grade 3-4,the wet wear resistance level is Grade 3,and the color fastness to dry/wet rubbing reach Grade 4-5.
