Description
본 발명은 흡,차음용 적층체에 관한 것이다. 보다 상세하게는 본 발명은 자동차용, 건축내,외장용 및 각종 쿠션 내장용 등으로 사용되면서 소음을 완벽하게 차단할 수 있는 흡,차음용 적층체에 관한 것이다.The present invention relates to a laminate for sound absorption and sound insulation. More specifically, the present invention relates to a sound absorbing and insulating layered laminate that can completely block noise while being used for automobiles, building interiors, exteriors, and various cushion interiors.
생활의 여러 분야에서 각종의 적층체들이 많이 사용되고 있다.Various laminates are widely used in various fields of life.
자동차의 경우를 예로 들면, 헤드라이너(Head liner), 도어트림(Door trim), 리어쉘프(Rear shelf), 트렁크매트(Trunk mat), 카매트(Car mat), 본네트(Bonnet) 등에 적층체들이 부착되며, 이들은 대체로 지류, 비닐, 섬유편물, 부직포 및 펠트 중 하나 이상의 조합으로 이루어진 중첩물로 되어 있다. 이들의 기능으로는 주로 차량의 내부를 보다 안락하게 보이도록 장식하는 내장기능, 차량의 내부열을 보존하거나 외기의 열을 차단하는 보온기능, 외부의 소음이 내부로 전달되는 것을 방지하기 위한 차음 및 흡음기능 또는 충격을 완화하기 위한 쿠션기능 등을 들 수 있다.For example, in the case of automobiles, laminates such as a head liner, a door trim, a rear shelf, a trunk mat, a car mat, and a bonnet may be used. Attached, they are generally composed of an overlap consisting of a combination of one or more of paper, vinyl, fibrous knit, nonwoven and felt. These functions mainly include a built-in function to decorate the inside of the vehicle to make it look more comfortable, a thermal insulation function to preserve the internal heat of the vehicle or block the heat of the outside air, and sound insulation and sound absorption to prevent the transmission of external noise to the inside. And a cushion function for mitigating a function or shock.
따라서, 이러한 중첩물들이 갖추어야 할 성능으로서는 미려한 외관, 보온성, 차음성, 흡음성 및 완충성 등이 우수하여야 하며 또한 차량의 중량을 감소시키기 위하여 경량이어야 할 뿐만 아니라 차량의 복잡한 내부구조 및 차종의 변화에 따른 구조변화에 잘 적응하여 성형될 수 있어야 하므로 성형성이 우수하여야 한다.Therefore, the performance of these superpositions should be excellent in beautiful appearance, warmth, sound insulation, sound absorption and cushioning, and should not only be lightweight in order to reduce the weight of the vehicle, but also change in the complex internal structure and type of the vehicle. It should be able to be molded by adapting well to structural changes according to the moldability.
이러한 쿠션 내장재용 부직포 중첩물로서 종래에 여러가지가 사용되어 왔지만 대부분 유사한 구조로 되어 있으며, 그 일례를 도 1에 개략적으로 도시하였다.As a nonwoven fabric superposition for such cushion interior material, various kinds have been used in the past, but most have a similar structure, and an example thereof is schematically illustrated in FIG. 1.
도 1은 종래의 자동차 천정 내장재(Head liner)의 소재구성 및 형태를 나타내기 위하여 부분적으로 분리하여 전개한 사시도로서, 자동차의 헤드라이너로 사용되어 왔던 것이다. 이는 제1층(14)과 제2층(16)으로 구분될 수 있으며, 제1층(14)은 다시 자동차 천정에 제1층(14) 자체를 밀착하여 부착시키기 위한 펠트(4) 표면의 접착제면을 보호하기 위해 최상면에 위치되며, 접착제면쪽에 이형제가 도포되어 있는 이형지(2)와, 보온, 흡음 및 차음기능을 하는 펠트(4)와 펠트(4) 저면의 표면 흐트러짐 및 오염을 방지하기 위한 비닐지(6)들이 적층되어 구성된다. 제2층(16)은 제1층(14)의 형태를 유지할 수 있도록 보강하기 위한 것으로서 두께 2 내지 5mm 정도의 굽힘에 대한 저항력이 강한 후판지(8)가 상층에 위치하고, 후판지(8)의 저면에는 표면 쿠션을 위한 스펀지(10)가 부착되며 스펀지(10)의 저면에는 표면마감 및 장식을 위하여 표면가공된 섬유편물(12)이 부착되어 적층되어 있다.FIG. 1 is a perspective view partially developed to show the material structure and shape of a conventional automotive ceiling liner, which has been used as a headliner of an automobile. This may be divided into a first layer 14 and a second layer 16, the first layer 14 of the surface of the felt (4) for attaching the first layer 14 itself in close contact with the vehicle ceiling again. Located on the top surface to protect the adhesive surface, release paper (2) having a release agent applied to the adhesive surface, and the surface of the felt 4 and the bottom surface of the felt (4) to keep warm, sound absorption and sound insulation, and to prevent contamination The plastic sheets 6 to be laminated are configured. The second layer 16 is for reinforcing the shape of the first layer 14, and a thick cardboard 8 having a strong resistance to bending about 2 to 5 mm thick is located on the upper layer, and the thick cardboard 8 The bottom surface of the sponge 10 for the surface cushion is attached, and the bottom surface of the sponge 10 is laminated with a surface-finished fabric knitted fabric 12 for the surface finish and decoration.
상기 펠트(4)의 두께는 약 5 내지 15mm 정도이며, 상기 스펀지(10)의 두께는 약 2 내지 5mm 정도이다. 상기 예는 종래 쿠션 내장재용 부직포 중첩물의 일례이나, 대체로 상기 예와 같은 구성에서 크게 벗어나지 않았다.The thickness of the felt 4 is about 5 to 15 mm, and the thickness of the sponge 10 is about 2 to 5 mm. The above example is an example of a conventional nonwoven fabric for cushion interior material, but generally does not deviate significantly from the configuration as the above example.
이와 같이 종래의 쿠션 내장재용 부직포 중첩물은 적어도 5층이상의 다층으로 되어 있고, 지(紙), 비닐, 펠트, 후판지, 스펀지, 섬유편물 등 여러가지 소재로 이루어져 있어서 제조과정이 번거로우며, 제조비용이 상승하는 등의 문제점이 있었으며, 폐기시에 효과적으로 재생하여 활용할 수 없다는 단점이 있었다. 또한, 흡음성과 차음성에 있어서도 충분한 효과를 내지 못한다는 단점이 있었다.As described above, the conventional nonwoven fabric for cushion interior material has a multilayer of at least five layers, and is made of various materials such as paper, vinyl, felt, thick paper, sponge, fiber knitted fabric, and the manufacturing process is cumbersome, and manufacturing cost There was a problem such as rising, there was a disadvantage that can not effectively recycle and utilize at the time of disposal. In addition, there is a disadvantage in that it does not have a sufficient effect in sound absorption and sound insulation.
한편 도 2에는 종래의 범용의 쿠션 내장재용 부직포 중첩물을 부분적으로 분리하여 전개한 사시도를 나타내었으며, 이는 제일 상층부에 저융점폴리에스터단섬유와 고융점폴리에스터단섬유가 20 : 80 내지 80 : 20의 비율로 혼합되어 이루어진 저밀도연질부직포(20)가 위치하고, 그 하부에 역시 저융점폴리에스터단섬유와 고융점폴리에스터단섬유가 20 : 80 내지 80 : 20의 비율로 혼합되어 이루어진 고밀도경질부직포(22)가 위치하며, 그 하부에 마감 또는 장식용의 섬유직편물(24)이 위치되도록 적층하고, 150 내지 250℃ 정도로 가열하는 것에 의하여 상기 저밀도연질부직포(20)와 고밀도연질부직포 중의 저융점폴리에스터단섬유의 가열에 의한 부분용융에 의하여 각 층들을 서로 열융착시켜 적층시킨 것이다.On the other hand, Figure 2 shows a perspective view of the conventional non-woven superposition of the general non-woven fabric for the cushion interior material is partially separated and developed, which is a low melting polyester short fibers and a high melting polyester short fibers 20: 80 to 80: A low density soft nonwoven fabric 20, which is mixed at a ratio of 20, is positioned, and a low melting polyester short fiber and a high melting polyester short fiber are also mixed at a ratio of 20:80 to 80:20 at a lower portion thereof. (22) is located, the lower density soft non-woven fabric 20 and the low melting point poly in the high-density soft nonwoven fabric by laminating so that the finishing or decorative fibrous fabric (24) is located below, and heated to about 150 to 250 ℃ The layers are thermally fused to each other by partial melting by heating the ester short fibers.
그러나, 이러한 종래의 부직포 중첩물도 완벽한 흡음 및 차음효과를 발휘하기에는 부족한 것으로서, 보다 완벽한 차음효과를 낼 수 있는 새로운 적층체의 개발이 요구되었다.However, such a conventional nonwoven fabric laminate is also insufficient to exhibit a perfect sound absorption and sound insulation effect, and the development of a new laminate capable of producing a more perfect sound insulation effect has been required.
본 발명의 목적은 자동차용, 건축내,외장용 및 각종 쿠션 내장용 등으로 사용되면서 소음을 완벽하게 차단할 수 있는 흡,차음용 적층체를 제공하는 데 있다.It is an object of the present invention to provide a sound absorbing and insulating laminate that can completely block noise while being used for automobiles, interiors, exteriors, and interiors of various cushions.
