摘要：Waterborne synthetic leather was fabricated by wet solidification process. Effect of polyurethane impregnating solution concentration, concentration of lanthanum acetate, coagulation bath temperature and solidification time on tear strength and average aperture are examined. The results show that concentration of lanthanum acetate and the solidification time are the main influencing factors. Through research, the low temperature differential temperature solidification method has a good effect on pore formation. The optimized wet solidification process has a lanthanum acetate concentration of 10%, a solidification temperature of 21°C, a solidification time of 9 min, and a polyurethane impregnating solution concentration of 12%. These surfaces are expected to be of interest in wide variety of applications.
