A novel epoxy modified waterborne polyurethane(WPU) emulsion has been synthesized through using polypropylene carbonate diols(PPC) as soft segment material,1,4-butanediol(BDO) and toluene diisocyanate(TDI) as hard segment materials,dimethylol propionic acid(DMPA) as hydrophilic chain extender and trimethylolpropane(TMP) as crosslinking agent,which performed well on the metal substrate. The effects ofn(—NCO)/n(—OH),the amount of DMPA and epoxy resin,and the neutralizing agent and neutralization degree on the properties and storage stability of WPU emulsion were discussed. Finally, the optimum synthesis conditions were determined.
