| description | The invention provides a double-component polyurethane sealant and a preparation method and application thereof. The sealant comprises a component A and a component B, wherein the component A is prepared from the components in parts by mass: 25-40 parts of hydroxyl terminated polyurethane prepolymer, 7.5-9.4 parts of a plasticizer, 0.5-2.0 parts of a coupling agent, 50-65 parts of a filler and 0.1-0.5 part of a first catalyst; the component B comprises liquid aromatic isocyanate; the hydroxyl terminated polyurethane prepolymer is obtained by a reaction of 50-70 parts of polyol and 10-40 partsof aliphatic isocyanate, the mass ratio of the component A to the component B is 3 to 1-6 to 1, the double-component polyurethane sealant is a pouring type sealant, has the characteristics of environmental protection, self-leveling, high curing speed, high bonding strength after curing and the like, and can be applied to the manufacture of large plate-shaped glass and glass handrails and pouring and sealing in an U-shaped |
