The invention relates to the field of products of sound insulation material, solves the problems in the prior art that the sound insulation material is poor in sound insulation effect, is incomprehensive in high and
low frequency sound insulation, causes
pollution and is easy to age, and provides an efficient sound insulation material and a manufacturing method thereof. The efficient sound insulation material includes a sound
insulation layer, a sound
absorption layer, and a bubble layer, wherein the bubble layer is located between the sound
insulation layer and the sound
absorption layer. The sound
absorption layer is made of a sound insulation compound, and the sound insulation compound is prepared by raw materials of the following substances: a
thermoplastic resin, inorganic fillers, and a
foaming agent, wherein the inorganic fillers account for 15-80wt%, the
foaming agent accounts for 5-15wt%, and the rest is the
thermoplastic resin. In the efficient sound insulation material, the fillers with different particle diameters correspond to sound
waves of different wave bands or frequencies, and thus consumption of
sound energy of different frequencies is relatively comprehensive, and the sound insulation effect is good, so the sound insulation material is suitable for popularization and application.
