| Abstract: | Series of waterborne polyurethane dispersion and film therefrom are prepared under different conditions with poly (tetramethylene oxide) (PTMG-1000), isophorone diisocyanate (IPDI) and TDI as main materials, dimethylol propionic acid (DMPA) as hydrophilic chain extender, 1,4-butanediol (BDO) and ethylenediamine (EA) as micromolecular chain extender. The effects of molecular structure and dispersion conditions on the stability of emulsion and properties of emulsion film are analyzed by studying the hardness, water absorption, adhesion and etc. of the emulsion film. |

| Keywords: | waterborne polyurethane stability of emulsion hardness water resistance |
