The present invention provides an acrylic damping adhesive. The acrylic damping adhesive comprises a crosslinked structure of a carboxy-containing acrylic polymer with a glass transition temperature less than or equal to −20° C. and a carboxy-containing acrylic polymer with a glass transition temperature ranging from 20° C. to 50° C. The acrylic damping adhesive according to technical solutions of the present invention exhibits double damping peaks in a rheological curve, and thus has a wider damping temperature range (the damping temperature range is greater than or equal to 50° C., and preferably greater than or equal to 90° C.), a higher frequency response of damping, and higher system stability.
