Description

Technical field[0001]The present invention belongs to the technical field of polymer material, and more particularly to a resin emulsion and a preparation method thereof.Background technique[0002]Organic Polymer Damping Coatings are special functional coatings with vibration damping, noise reduction and certain sealing, can be widely used in airplanes, ships, and various mechanical vibration and noise reduction. Today, the damping coatings commonly used in the vehicle noise environment are represented by asphalt, neoprene, and nitrile rubber water-based coatings, but there is easy combustion, high temperature requirements, poor substrate adhesion, and production The process is complex, the cost is higher, and it is not convenient for mass production and use. In the damping coating, the aqueous acrylic damping coatings are widely used due to their excellent damping properties to construct coating, no environmental pollution and low cost, and low cost.[0003]The damping performance of ...
