摘要
通过引入硅氧烷基团对端—NCO基进行化学改性,合成了硅氧烷基团封端的聚氨酯预聚体,解决了聚醚型单组分湿固化聚氨酯防水涂料易起泡的问题。
Polyurethane pre-polymer with siloxane end group was synthesized by introducing siloxane group to chemically modify --NCO end group, which avoids air bubbling of polyether one component moisture-curable polyurethane waterproofing coating.
