Damping water-based resin

The invention discloses a damping water-based resin. The formula of the damping water-based resin comprises the following raw materials: an acrylate monomer with a damping structure function, an acrylate monomer mixture, a cross-linking monomer 1, a cross-linking monomer 2, an emulsifier, an initiator and deionized water. A dihydric alcohol compound and a hindered phenol compound are introduced into an acrylate structure through a chemical modification technology to prepare an acrylate monomer which contains hindered phenol and a hydroxyl structure and has a damping structure function; and then, on the basis that a series of macromolecular water-based damping resin is successfully prepared through an emulsion copolymerization preparation technology, the macromolecular water-based damping water-based resin is prepared by screening hindered phenol and acrylate monomers with different chemical structures; and the damping water-based resin has a wider temperature range and longer service time; and the damping wat
