Abstract
The present application discloses a low-viscosity silane-terminated resin for a sealant and a preparation method thereof, and belongs to the technical field of sealants. The present application firstly uses an alcohol initiator, an alkali earth metal and epoxy alkane to synthesize a low-molecular-weight polymer, then adds a polymetallic cyanide catalyst and the epoxy alkane to synthesize a high-molecular-weight polymer, and finally adds carboxylate metal and isocyanate silane to react to obtain the silane-terminated resin. A short chain segment is successfully introduced into a molecule, and an original molecular crystal is destroyed, to achieve intramolecular plasticization, so that its molecular chain becomes flexible and is easy to move, thus the purpose of reducing viscosity is achieved.
