Preparation of weather-resistant single-component silane modified polyether sealant

The invention discloses preparation of a weather-resistant single-component silane modified polyether sealant. The sealant is mainly prepared from silane modified polyether resin, alkoxy-terminated polydimethylsiloxane, a plasticizer, a cross-linking agent, a filler, a coupling agent, a catalyst, a functional aid and a cosolvent. The silane modified polyether sealant prepared by the invention has excellent weather resistance. 本发明公开了一种耐候单组份硅烷改性聚醚密封胶的制备，本发明的密封胶主要由硅烷改性聚醚树脂、端烷氧基聚二甲基硅氧烷、增塑剂、交联剂、填料、偶联剂、催化剂、功能性助剂、助溶剂制备而成。本发明制备的硅烷改性聚醚密封胶具有优异的耐候性能。
