Abstract
Disclosed is a method for manufacturing a soundproofing material by finely crushing a discarded car seat, mixing the crushed car seat with polyester fiber, low-melting polyester fiber such as LM PET, polypropylene fiber and hemp, and carding the resulting mixture, and a soundproofing material composition prepared thereby. The disclosed method allows recycling of polyurethane foam of the discarded car seat into a soundproofing material composition having superior appearance quality and soundproofing performance. The disclosed method also prevents generation of excessive static electricity and allows preparation of a soundproofing material with smooth surface.
