| Abstract: | The waterborne polyurethane was modified by the epoxy resin E44 and a inter-crosslinker TMP by the ways of crosslinking. The modified polyether waterborne polyurethane emulsion was synthesized using a small molecule chain extender BDO,a hydrophilic chain extender DMPA. The performance of emulsion was optimum when the content of E44 was 4%,the amount of DMPA and TMP were 9%-10% and 2%-3%, respectively. |
| Keywords: | waterbome polyurethane epoxy modified crosslink |
