| description | The invention relates to a prefabricated building polyurethane sealant, and a preparation method thereof. The prefabricated building polyurethane sealant comprises an anti-sagging agent; the anti-sagging agent is a hyperbranched polyurea formed via reaction of hyperbranched polyethylenimine with a single isocyanate terminated prepolymer, the hyperbranched polyethylenimine contains 10 to 30 nitrogen atoms, the single isocyanate terminated prepolymer is obtained via reaction of a diisocyanate monomer with a monohydric alcohol containing 3 to 12 carbon atoms. The prefabricated building polyurethane sealant possesses high adhesive force on cement and metal substrates, is high in flexibility, elongation percentage, and elastic resilience, is excellent in weather resistance, hydrolysis resistance, fatigue resistance, and thixotropic property, and is low in modulus; construction is convenient; and production technology is simple.
