摘要
本文研究了烷氧基硅烷改性型单组分湿固化聚氨酯密封胶的性能,分别讨论了不同烷氧基硅烷封端比例对单组分湿固化型聚氨酯密封胶的力学性能、发泡性以及表干时间的影响,还讨论了聚氨酯预聚物本身结构变化对烷氧基硅烷改性后密封胶性能的影响。
The paper examines siloxane modified one component moisture curable polyurethane sealant. Influence of different siloxane end capped ratios on mechanical properties, bubble foaming and tack free time of the sealant is discussed. Also, influence of structural change of polyurethane prepolymer itself on performance of the sealant modified by siloxane is discussed.
