A flame-retardant sealant based on modified polyether polymer

Sealant is a kind of sealing material that can fill the joint and the bonding interface indefinitely, and withstand the displacement and deformation of the joint. It is usually a paste-like material that connects the substrates into a whole after curing. Early sealants were made of dry (or non-dry) viscous materials, such as Zhejiang green, tar, natural (or synthetic) resin, and natural (or synthetic) rubber. There are currently three types of high-performance sealants: polysulfide sealants, silicone sealants and polyurethane sealants. Flame retardant sealant based on modified polyether polymer and its preparation method is a new type of modified sealant. The main chain of this type of polymer is polyether with hydrolyzable silane end groups.
