摘　　要：以硅烷改性聚醚(STP-E)为基础聚合物,添加催化剂、增塑剂等助剂,制备了一系列杂化STP-E弹性密封胶,重点讨论了聚合物种类、催化剂及增塑剂对密封胶固化性能的影响。实验结果表明,选用GENIOSIL STP-E30为基础聚合物、PPG-400为增塑剂、DMP-30为催化剂制备密封胶,能够获得最快的固化速度。A series of elastic STP-E hybrid sealants were prepared by using silane modified polyether （STP-E） as basic polymer, adding catalyst, plasticizer and various additives. The article discusses the influences of different basic polymers, catalysts and plasticizers on the curing performance of STP-E hybrid sealant. The results show that the fastest curing rate could be acquired by selecting GENIOSIL STP-E30 as basic polymer, PPG-400 as plasticizer, and DMP-30 as catalyst.
