摘要
论述了硅烷偶联剂的偶联机理及其作为封端剂、粘接促进剂和干燥剂在聚氨酯密封胶中的应用。介绍了硅烷偶联剂改性聚氨酯预聚物的方法和密封胶的配制以及不同的硅烷偶联剂对改性聚氨酯密封胶性能的影响。
The coupling mechanism of silane coupler and its use as endcapper,adhesion promoter and dehydrating agent in polyurethane sealant are discussed. The preparation method of silylated ~polyurethane sealant and the influences of different silanes on sealant properties are also described.
