Description
본 발명은 자동차의 대쉬 판넬 흡차음 내장재 및 그 제조방법에 관한 것으로서, 더욱 상세하게는 대쉬 판넬 흡차음 내장재를 구성시 친환경적인 폴리에스터(Polyester)계열의 열융착사(Low meltingyarm)와, 폴리에틸렌 테레프 탈레이트(polyethyleneterephthalate)를 사용하여 재활용이 가능하도록 구성된 대쉬 판넬 흡차음 내장재를 제조하고, 상기 대쉬 판넬 흡차음 내장재를 제조하는 방법에 관한 것이다.BACKGROUND OF THE
주지하는 바와 같이 자동차 차체의 각 부위에는 흡차음 위해 각종 내장재가 부착되는데, 이러한 흡차음을 위한 내장재는 자동차의 엔진룸이나 동력전달계통에서 발생하는 소음을 차단하는 차음기능과 자체의 물리적 특성에 의해 소음을 흡수하여 자동차 실내에 소음이 침투되는 것을 막기 위해 설치되는 것으로 흡차음 설계는 자동차의 설계에 있어서 매우 중요한 요소 가운데 하나인 것을 부인할 수 없을 것이다.As is well known, various interior materials are attached to each part of the vehicle body, and the interior materials for the sound absorbing and soundproofing are made by the sound insulation function that blocks noise generated from the engine room or the power transmission system of the vehicle and its physical characteristics. It is installed to absorb noise and prevent noise from penetrating the interior of the car, and it can not be denied that the sound absorption design is one of the most important elements in the design of the vehicle.
종래 상기와 같은 각종의 내장재들 중에 본 발명에서는 자동차의 대쉬 판넬 흡차음 내장재의 단점을 살펴본다.Among the various interior materials as described above, the present invention looks at the disadvantages of the dash panel sound absorbing and interior materials of automobiles.
먼저, 대쉬 판넬 흡차음 내장재의 부직포는 물론이고, 상기 부직포를 적층하여 접착하기 위해 사용되는 접착제인 아크릴 수지와 에틸렌 비닐 초산(Ethylen Vinyl Acetate)은 재활용이 불가능하여 친환경적이지 못한 단점이 있다.First, as well as the non-woven fabric of the dash panel sound absorbing and insulating material, acrylic resin and ethylene vinyl acetate (Ethylen Vinyl Acetate), which are adhesives used for laminating and bonding the non-woven fabric, are not recycled and thus are not environmentally friendly.
그리고, 흡차음이 뛰어나고 성형이 뛰어나 폴리우레탄 폼 소재를 많이 사용하고 있으나, 폴리우레탄 폼은 폴리프로필렌 글라이콜(Polypropylene Glycol)과 마이크로소프트 오피스 도큐먼트 이미징(Methylen Diphenyl Diissocyanate)을 6:4의 비율로 혼합하여 만드는데 이 두 가지 재료는 환경 유해물질로 재활용이 불가능하다.In addition, although the sound absorbing sound is excellent and the molding is excellent, the polyurethane foam material is used a lot, but the polyurethane foam is composed of polypropylene glycol and Microsoft office document imaging (Methylen Diphenyl Diissocyanate) in a ratio of 6: 4. These two materials are mixed and cannot be recycled as environmentally hazardous substances.
또한, 상기와 같이 구성된 폴리우레탄 폼의 경우 금호미쯔이화학, 한국폴리올 등 대기업이 생산하고 있어 재료의 가격이 비싸고 특히 방음, 흡음, 차음 및 장착성이 떨어지고 무거운 단점이 있다.In addition, in the case of the polyurethane foam configured as described above is produced by large companies such as Kumho Mitsui Chemicals, Korea Polyol, the price of the material is expensive, in particular soundproofing, sound absorption, sound insulation and mounting is poor and heavy disadvantages.
상기 우레탄 폼과 에틸렌 비닐 초산 이외 고밀도 부직포에 대한 연구도 진행되고 있으나 적층 시 사용되는 점착 수지인 아크릴 수지는 재활용이 안 되는 단점을 가지고 있다.In addition to the urethane foam and ethylene vinyl acetate, research on high-density nonwoven fabrics is also in progress, but an acrylic resin, which is an adhesive resin used for lamination, has a disadvantage of not being recycled.
그리고, 대체 소재로는 Toyobo사의 ELK 소재와 Teijin 사의 Fusion 제품이 최근에 개발되어 차량 내장재의 쿠션 부분부터 적용이 되어가고 있으나, 대쉬 판넬 흡차음 내장재로서 요구되는 방음, 흡음, 차음 및 장착성이 떨어지는 단점을 가지고 있다.As alternative materials, Toyobo's ELK material and Teijin's Fusion products have been recently developed and applied from the cushion portion of the vehicle interior material. Have
또한, 친환경성을 고려하여 재활용이 가능한 섬유소재 및 부직포 개발을 시도하고 있으나, 기술 수준이 초기에 있기 때문에 방음, 흡음, 차음 기능 향상되고, 또 친환경적인 자동차의 대쉬 판넬 흡차음 내장재를 제공하지 못하고 있는 실정에 있다.In addition, we are trying to develop recyclable textile materials and nonwoven fabrics in consideration of eco-friendliness.However, due to the early technology level, sound insulation, sound absorption and sound insulation are improved, and eco-friendly car dash panels are not provided. There is a situation.
상기와 같은 문제점을 해결하기 위한 본 발명은 흡음 부직포와 파일(Pile) 부직포, 그리고 폴리에틸렌 테레프탈레이트 (polyethyleneterephthalate) 수지가 접목이 되어 구성된 경량화, 방음, 흡음, 차음 효과를 극대화 시킬 수 있게 하며,The present invention for solving the above problems is to maximize the light-weight, soundproofing, sound-absorbing, sound-absorbing effect of the sound-absorbing nonwoven fabric, the pile (Pile) nonwoven fabric, and polyethylene terephthalate (polyethyleneterephthalate) resin is grafted,
또한, 재활용이 가능한 친환경적인 열융착사로 흡음 부직포와 파일(Pile) 부직포, 그리고 폴리에틸렌 테레프탈레이트 (polyethyleneterephthalate)를 사용해서 상호 접착하여 자동차의 대쉬 판넬 흡차음 내장재 및 그 제조방법을 제공하려는 것이다.In addition, it is an environmentally friendly heat-sealed yarn that can be recycled to provide a dash panel sound-absorbing and sound-absorbing material and a method of manufacturing the same by using a sound absorbing nonwoven fabric, a pile nonwoven fabric, and polyethylene terephthalate.
상기와 같은 목적을 달성하기 위해 본 발명에 의한 자동차의 대쉬 판넬 흡차음 내장재는, 열융착사(Low meltingyarm) 중에 중공사(hollow Fiber)와 열융착사로 구성된 흡음 부직포와 열융착사로 구성된 부직포와 열융착사로 형성된 파일로 파일부직포를 폴리에틸렌 테레프 탈레이트(polyethyleneterephthalate)에 의해서 접착된 것이며,In order to achieve the above object, the dash panel sound absorbing and insulating material for automobiles according to the present invention includes a non-woven fabric and a heat-absorbing non-woven fabric composed of a hollow fiber and a heat-fused yarn in a low meltingyarm. A pile formed of fused yarn is bonded to pile nonwoven fabric by polyethylene terephthalate,
상기 자동차의 대쉬 판넬 흡차음 내장재의 제조 방법은, 열융착사(Low meltingyarm) 중에 중공사(hollow Fiber)로 구성된 부직포 1장과, 열융착사로 구성된 1장이 니들펀칭에 의해서 일체로 구성하고, 또 열융착사로 구성된 부직포 1장과 열융착사로 형성된 파일을 니들펀칭에 의해서 일체로 구성하여 상호 폴리에틸렌 테레프 탈레이트에 의해서 접착하는 제조방법이 본 발명에 특징이다.The method for manufacturing the dash panel sound-absorbing sound-absorbing material interior material of the automobile includes one nonwoven fabric made of hollow fiber and one sheet made of heat-fused yarn in a low meltingyarm, which are integrally formed by needle punching. The present invention is characterized in that a nonwoven fabric composed of heat-fused yarn and a pile formed of heat-fused yarn are integrally formed by needle punching and bonded by mutual polyethylene terephthalate.
이상과 같은 본 발명에 의한 자동차의 대쉬 판넬 흡차음 내장재에 의하면, 열융착사로 구성된 중공사와 파일에 의해서 경량화와 방음, 흡음, 차음 효과와 장착성 및 생산성이 크게 향상되는 효과가 있으며,According to the dash panel sound absorbing and insulating material of the automobile according to the present invention as described above, by the hollow fiber and pile composed of heat-sealed yarn, there is an effect of greatly improving the weight and sound insulation, sound absorption, sound insulation effect and mounting and productivity,
또, 친환경적인 폴리에스터(Polyester)계열의 열융착사(Low meltingyarm)와 폴리에틸렌 테레프 탈레이트(polyethyleneterephthalate)를 사용하였기 때문에 재활용이 가능하고, 중량이 우레탄 폼에 절반으로 경량화에 기여하여 자동차 연비를 좋게 하는 효과가 기대되며,In addition, it uses eco-friendly polyester-based low meltingyarm and polyethylene terephthalate, which can be recycled. I expect good effect
