The application provides a wet base surface bondable sealant, a preparation method and application thereof, and relates to the technical field of functional materials. The sealant is composed of component A and component B with a mass ratio of (2-10):1; wherein, component A includes the following components by mass: 10-50 parts of silane-modified polyether resin, 0.5 ~4 parts of water scavenger, 5-60 parts of plasticizer, 20-70 parts of filler, 0.1-1 part of catalyst, 0.2-2 parts of co-crosslinking agent, and 0.1-3 parts of light stabilizer; B component includes the following Components in parts by mass: 1-50 parts of rubber latex and 5-50 parts of emulsified asphalt. Since rubber latex and emulsified asphalt are introduced into the silane-modified polyether resin system in this application, the two can be combined with the silane-modified polyether resin to form intermolecular forces, thereby increasing the polarity and cohesion of the sealant. , which improves the bond strength of the sealant on the wet base surface. |
