| Abstract: | The waterborne polyurethane(WPU) emulsion with solid content of 30%was synthesized with poly ether 210(N -210),isophorone diisocyanate(IPDI) as basic monomers,diethylene glycol(EX) as chain extender,dimethylol propionic acid(DMPA) as the hydrophilic chain extender.A series of WPU emulsions modified with silica sol were prepared by mechanical dispersion of silica sol in WPU emulsion at a specified amount.The results showed that silica sol was evenly dispersed in the WPU.There was interaction between silica p... |
