Bi-component silane modified polyether sealing material and preparation method thereof

The invention discloses a bi-component silane modified polyether sealing material and a preparation method thereof. The bi-component silane modified polyether sealing material comprises silane modified polyether, a plasticizer, an incremental filler A, a reinforcing filler, a toner, a thixotropic agent, a light stabilizer, hollow glass microspheres, a cross-linking agent, a coupling agent, an incremental filler B, an organic tin catalyst and a titanium catalyst. According to the bi-component silane modified polyether sealing material, organic tin is partially replaced with the titanium catalyst and is low in content, so that the harm of organic tin can be reduced; the production process is simple, a high temperature dehydration process is omitted, and the cost is low; the external and internal parts of a glue layer are simultaneously cured by virtue of moisture of the glue layer during curing, so that the defects that single-component silane modified polyether sealing glue is cured from outside to inside by virtue of moisture and the dept curing is slow are overcome, and the variation of curing rate along the external environment is small, so that the production efficiency is greatly improved; the bi-component silane modified polyether sealing material has good construction stability and can be widely applied to the fields of buildings, automobiles, locomotives, electric products and the like.
