摘要
针对不同类型的有机硅改性剂在制备聚氨酯水分散体方面的应用,介绍了近年来在水分散有机硅-聚氨酯嵌段共聚物制备方法上所取得的进展,重点讨论了有机硅在提高水性聚氨酯的耐水性、热稳定性和力学性能方面的突出作用,并展望了该类复合材料的发展方向。
Focusing on several kinds of silicone as modifier; waterborne silicone - polyurethane bolck polymers were introduced. Especially, the significant effect of silicone on water resistance, thermal stability and mechanical properties of waterborne polyurethane were discussed. The developing tendency of this composite materials were prospected.
