SILANE-MODIFIED POLYETHER SEALANT COMPOSITION AND SILANE-MODIFIED POLYETHER SEALANT AND PREPARATION METHOD THEREFOR

摘要

Provided are a silane-modified polyether sealant composition and a silane-modified polyether sealant and a preparation method therefor. The silane-modified polyether sealant composition contains: an alkoxy-terminated polyether, calcium carbonate, white carbon black, an organic chelate tin catalyst, a plasticizer, a water removing agent and a tackifier, wherein the apparent viscosity of the alkoxy-terminated polyether is 7000-16000 mPa·s, and the tackifier is one or more of a bisaminosilane tackifier, a monoaminosilane tackifier and an alkoxysilane tackifier.
