20130009087 | METHOD FOR MANUFACTURING SOUNDPROOFING MATERIAL USING POLYURETHANE FOAM FROM CAR SEAT FOAM AND COMPOSITION THEREOF PREPARED THEREBY - 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. | 01-10-2013 |
20130026262 | APPARATUS FOR SELECTIVELY SEPARATING POLYURETHANE FOAM AND FIBER FROM AUTOMOBILE SHREDDER RESIDUE - The present invention provides an apparatus for selectively separating polyurethane foam and fiber from Automobile Shredder Residue (ASR). The apparatus includes a first separator, a second separator, and a third separator. The first separator primarily separates fine particles, such as dirt or glass pieces, from the ASR at a front portion thereof and separates large-sized polyurethane foam and fiber from the ASR at a rear portion thereof. The second separator grinds remaining materials after the primary separation of the first separator. The third separator separates medium-sized polyurethane foam and fiber from the remaining materials after the separation of the first separator and secondarily separates plastics, rubber, and other materials. | 01-31-2013 |
20130341120 | SOUNDPROOF MATERIAL USING POLYURETHANE FOAM FROM CAR SEAT AND FABRICATION PROCESS THEREOF - Disclosed is a soundproof material fabricated using recycled polyurethane foam from waste seats and a process of fabricating the same, and more particularly, a soundproof material fabricated by stacking a thermoplastic polymer on a sound absorbing material including recycled polyurethane foam from seats from end-of-life vehicles and a process of fabricating the same. Use of recycled resources provides an eco-friendly impact, reduces manufacturing costs for parts, and allows for improved mechanical rigidity and sound insulating properties. The soundproof material may be applied to various automobile parts such as package trays, luggage coverings, covering shelves, and isolation pads. | 12-26-2013 |
