Abstract: PURPOSE: A soundproofing material and a manufacturing method thereof are provided to use a PP resin for improving the soundproof property of the material, and to prevent the productivity degradation. CONSTITUTION: A manufacturing method of a soundproofing material comprises the following steps: forming a mixture by dissolving a PP resin and nanoclay into a solvent; and evaporating the solvent from the mixture. The formation process for the mixture is performed by mixing 2~10wt% of nanoclay for the total amount of the mixture. The mass ratio of the PP resin and the solvent is 1:3~1:5. The content rate of the solvent is under 0.5~2wt%.
