The invention discloses a preparation method of a nano sound insulation material. BaSO4, a MgAl2O4/Fe-MOF nano material, PVC (polyvinyl chloride) resin, polyolefin plastomer (POP), stearic acid and chlorinated paraffin are taken as main raw materials, an organic metal porous complex Fe-MOF is prepared by adopting an electrolysis technology, MgAl2O4 and a metal crystal material are subjected to silicone coupling treatment, so that sound insulation functional particles with different grain sizes are uniformly distributed in PVC resin according to a volume complementary filling principle and formelastic interface bonding with substrate resin, the spatial topological advantage of a metal modified skeleton structure can be brought into full play, the influence to the environment is less, and the obtained product is good in sound insulation property and wide in application range, and can be widely applied to preparation process of various kinds of sound insulation materials so as to performthe sound insulation property.
