Abstract
Provided is an unconstrained vibration damping metal sheet with foam pores. The unconstrained vibration damping metal sheet of the present invention comprises: a metal sheet; an organic-inorganic pretreatment layer containing an acrylic resin formed on the metal sheet; and a foam resin layer formed on the pretreatment layer, the foam resin layer containing, based on weight: thereof, a thermoplastic polyvinyl chloride resin: 40-80%, a plasticizer: 5-40%, a foaming agent: 0.1-10%, an oxide-based crosslinker: 1-4%, and spherical silica: 1-10%.
