Description
본 발명은 자동차 및 건축용 내장 흡음 단열재의 제조방법 및 그 흡음 단열재에 관한 것으로서, 특히, PET(polyethylen terephthalate)생산시 발생되는 부산물을 재가공한 폴리에스테르와 저융점화이버를 원료로 한 흡음 단열재를 제조 공급함으로써, 자원의 재활용과 그로 인한 비용절감 및 인체 유해 요소가 없는 친환경적 소재에 따른 품질향상을 위한 것이다.The present invention relates to a method for manufacturing a sound-absorbing insulating material for automobiles and buildings, and to a sound-absorbing insulating material, in particular, manufacturing and supplying a sound-absorbing insulating material made of polyester and low-melting fiber reprocessed by-products produced during the production of PET (polyethylen terephthalate) By doing so, it is intended to improve the quality of environmentally friendly materials that are free of resources and thereby reduce costs and human hazards.
일반적으로 자동차의 경우, 헤드 라이너(Head liner), 도어 트림(Door trim), 리어 쉘프(Rear shelf), 트렁크 매트(Trunk mat), 카 매트(Car mat), 본네트(Bonnet) 등에 흡음 단열재 등이 부착되며, 이들은 대체로 지류, 비닐, 섬유편물, 부직포 및 펠트 중 하나 이상의 조합으로 이루어진 중첨물로 되어 있고, 이들은 차량의 내부 열을 보존하거나 외기의 열을 차단하는 보온기능과 외부의 소음이 내부로 전달되는 것을 방지하기 위한 차음 및 흡음 기능을 가진다.BACKGROUND ART In the case of automobiles, sound insulation such as a head liner, a door trim, a rear shelf, a trunk mat, a car mat, a bonnet, etc. They are usually made of a polyimide composed of a combination of one or more of tributaries, vinyl, fibrous knits, nonwovens and felts, and they have a thermal insulation and external noise to keep the interior heat of the vehicle or block the heat of the outside air. It has a sound insulation and sound absorption function to prevent transmission.
이러한 흡음 단열재가 갖추어야 할 조건으로는 보온성, 차음성 및 흡읍성 등이 우수하여야 하고, 차량의 중량을 감소시키기 위하여 경량이어야 할 뿐만 아니라, 차량의 복잡한 내부 구조 및 차종의 변화에 따른 구조 변화에 잘 적응하여 성형될 수 있어야 하므로 성형성이 우수하여야 한다.Such sound absorbing insulation materials should be excellent in heat insulation, sound insulation and air intake properties, and should be light in order to reduce the weight of the vehicle, as well as structural changes caused by the complex internal structure of the vehicle and the change of the vehicle type. It should be able to adapt and be molded, so the moldability should be excellent.
이에, 종래의 자동차 내장용 흡음 단열재는 최상부에 저융점 폴리에스테르 단섬유와 고융점 폴리에스테르 단섬유가 혼합되어 이루어진 저밀도 연질부직포가 위치하고, 중간부에는 저융점 폴리에스테르 단섬유와 고융점 폴리에스테르 단섬유가 혼합되어 이루어진 고밀도 경질부직포가 위치하며, 하부에는 섬유편직물이 위치되도록 적층한 후, 150∼250℃ 정도로 가열하여 상기 저밀도 연질부직포와 고밀도 경질부직포 중의 저융점 폴리에스테르 단섬유의 가열에 의한 부분 용융에 의해 각 층들이 서로 열융착되어 적층된 것을 주로 사용하여 왔다.Thus, the conventional sound absorbing insulation for automobile interior is a low-density soft nonwoven fabric made of a mixture of low-melting polyester short fibers and high-melting polyester short fibers at the top, and the low-melting polyester short fibers and high-melting polyester ends in the middle portion The high-density rigid nonwoven fabric is formed by mixing the fibers, the lower portion of the high-density soft nonwoven fabric and the high-density rigid nonwoven fabric of the low-density polyester non-woven fabric is laminated by laminating so that the fiber knitted fabric is located at the lower portion and heated It has been mainly used that the layers are thermally bonded to each other by melting.
그러나, 이와 같은 종래의 적층형 흡음 단열재는 각 층을 별도로 제작한 다음 열융착에 의해 완성함으로써 제작과정이 복잡하고, 제작비용이 과도하게 소용되며, 각 층간에 공극이 발생될 우려가 높아 충분한 흡음 및 차음효과와 단열효과를 얻기에 부족한 문제점이 있는 것이었다.However, such a conventional laminated sound absorbing insulation material is manufactured by separately manufacturing each layer and then completed by thermal fusion, which makes the manufacturing process complicated, excessively expensive production costs, and there is a high possibility of generating voids between the layers, thus providing sufficient sound absorption and There was a problem of insufficient sound insulation and insulation effects.
또한, 종래의 또 다른 흡음 단열재로 폴리프로필렌이나 석고 등을 가공, 처리한 보드형태가 있는데, 이러한 석고보드, 폴리프로필렌보드 등은 화학처리되어 생산되므로 악취가 나고, 성형 후 뒤틀림이나 변형이 일어나며, 환경호르몬의 발생 등으로 인한 인체 유해할 뿐 아니라, 고단가로 인해 경제적인 부담도 가중되는 등의 문제점들이 있는 것이었다.In addition, there is another conventional sound-absorbing heat insulating material in the form of a board processed and processed polypropylene or gypsum, such gypsum board, polypropylene board, etc. are produced by chemical treatment, resulting in odor, warping or deformation occurs after molding, Not only harmful to the human body due to the occurrence of environmental hormones, there are problems such as an economic burden due to high cost.
본 발명은 상기와 같은 종래 기술의 문제점을 해소하고자, PET(polyethylen terephthalate)생산시 발생되는 부산물을 재가공한 폴리에스테르와 저융점화이버를 원료로 한 흡음 단열재를 제조 공급함으로써, 자원의 재활용과 그로 인한 비용절감 및 인체 유해 요소가 없는 친환경적 소재에 따른 품질향상을 그 목적으로 한다.The present invention to solve the problems of the prior art as described above, by manufacturing and supplying a sound-absorbing insulation material made of polyester and low-melting fiber reprocessed by-products produced during the production of polyethylene (polyethylen terephthalate), recycling of resources and It aims to improve the quality according to eco-friendly materials without cost reduction and human harmful factors.
