【Abstract】 The progress on the self-crosslinking waterborne polyurethane at room temperature modified by organic silane coupling agent was summarized,including the preparations,self-crosslinking curing mechanism at room temperature and the relationship between the structures and properties. The performance of selfcrosslinking WPU modified by silane coupling agent,the preparations of WPU modified by silane coupling, and preparations of WPU modified by composite crosslinking silane coupling were discussed. Finally,the future developments and applications of the self-crosslinking waterborne polyurethane at room temperature modified by organic silane coupling agent were prospected.更多还原
