A modified aromatic amine-cured polybutadiene polyurethane urea adhesive sealant comprises, by weight, 65-90 parts of an isocyanate-terminated liquid polybutadiene resin and 10-35 parts of a modified aromatic amine curing agent. The isocyanate-terminated liquid polybutadiene resin is prepared by reacting hydroxyl-terminated polybutadiene rubber with an aliphatic diisocyanate in a molar ratio of 1:2.0-2.5, and the hydroxyl-terminated liquid polybutadiene has a number-average molecular weight of 1200-3000 and a hydroxyl value of 1.6-0.7 mmol / g. The modified aromatic amine curing agent is obtained by reacting aminobenzylamine, an acrylate monomer, and acrylonitrile in a molar ratio of 2:1:2, wherein the acrylate monomer is one or a mixture of two or more of 1,6-hexanediol diacrylate, neopentyl glycol diacrylate, and (octahydro-4,7-methylene-1H-indene-1,5-ylidene)bis(methylene) diacrylate. The prepared polybutadiene polyurethane urea has a microphase separation aggregation structure and has good adhesion properties to both polar and low-polar materials.
