Low cost and high efficient soundproof material and manufacturing method thereof

The invention relates to a low cost and high efficient soundproof material and a manufacturing method thereof, relates to the field of soundproof materials, solves the problems that in the prior art, soundproof materials do not have a prominent soundproofing effect, generate harmful gas, which can harm the human health, and have a high cost; and provides a low cost and high efficient soundproof material. The soundproof material comprises thermoplastic resin and an inorganic filling material, wherein the surface of the inorganic filling material has been processed by a coupling agent processing liquid, the inorganic filling material accounts for 15 to 80 wt% of the total weight of the soundproof material, and the balance being thermoplastic resin. In the soundproof material, the connections among the particles are abnormal, thus the internal friction of the incident sound waves is increased by the structure of the soundproof material, and a relaxation effect is generated to absorb the sound waves. Filling materials with different particle sizes are corresponding to waves in different wavelengths or frequencies, so the soundproof material can reduce sounds in different frequencies. Moreover the soundproof material has a good soundproof effect and is suitable for being promoted and used.
