Abstract The emulsion of different kinds of waterborne polyurethane was synthesized by the methods of physical blending and in-situ polymerization, in which home-made polyester and IPDI in the laboratory were used as raw materials and the addition of different amounts of nano-SiO₂ was operated afterwards. The average particle size, mechanical property, viscosity, water absorption ratio, transmittance ratio, adhesion strength of polyurethane were closely associated with the dosage and modification method of nano-SiO₂. As a conclusion, the optimal modified method was that the nano-SiO₂/waterborne polyurethane emulsion was synthesized using the in-situ polymerization with addition of 0.10% nano-SiO₂ modified by Tween-80, and then it was mixed with some auxiliary with appropriate proportion to make the leather-repairing agent.

Key words： waterborne polyurethane nano-SiO₂ modification in situ polymerization leather-repairing agent
