Description
본 고안은 자동차 등의 내부를 피복하는데 사용될 수 있는 내장재 적층체에 관한 것으로서, 보다 상세하게는 성형성과 방음성이 우수한 경량의 내장재 적층체에 관한 것이다.The present invention relates to a laminate of interior materials that can be used to coat the interior of automobiles, and more particularly, to a lightweight interior laminate that is excellent in formability and sound insulation.
통상, 자동차나 요트 등의 소형 선박 또는 컨테이너하우스(container house)와 같은 한정된 공간의 내부를 마감하고 장식하는데에는 방음성과 내열성을 갖는 적층체가 주로 사용되고 있으며, 종래의 내장재 적층체는, 도1에 도시한 바와 같이, 유리섬유나 레진펠트(resin felf) 또는 페이퍼보드(paper board)와 같은 중량의 단열, 방음소재로 된 기재로 기재층(2)을 형성하고, 상기 기재층(2)에 접착제층(4)을 사용하여 폴리에틸렌필름(Polyethylene film)과 같은 소재로 된 비닐층(6)과 원단이나 부직포 또는 폴리염화비닐쉬트(Poly vinyl chloride sheet)와 같은 소재로 된 마감재층(8)을 더 접착시켜서 구성되어진 것이 일반적으로 사용되었었다.In general, a laminate having soundproofing and heat resistance is mainly used for finishing and decorating an interior of a limited space such as a small ship such as a car or a yacht or a container house, and a conventional interior laminate is shown in FIG. As described above, the substrate layer 2 is formed of a substrate made of a heat insulating and soundproof material having a weight such as glass fiber, resin felf or paper board, and an adhesive layer is formed on the substrate layer 2. (4) further bonds a vinyl layer (6) made of a material such as polyethylene film and a finish layer (8) made of a material such as a fabric, a nonwoven fabric or a poly vinyl chloride sheet. It was generally used to make up the body.
그러나, 이러한 종래의 내장재 적층체는 기재층(2)을 구성하는 소재 자체가 비교적 중량이 많이 나가는 것들로서, 유리섬유가 사용되는 경우에는 유리섬유 자체가 무기물로서 중량이 많이 나가며, 또한 레진펠트 역시 통상의 펠트에 페놀수지 등의 열경화성 수지를 함침시켜 제조된 것으로서, 적층체 자체의 중량을 증가시키게 된다. 따라서, 이들을 소재로 하는 기재층(2)을 갖는 종래의 내장재 적층체를 자동차에 적용하였을 경우, 차량의 전체 하중이 증가하는 원인이 되어 연비의 감소를 초래하는 등의 문제점이 있었다.However, these conventional interior laminates are those materials that make up the base layer 2 are relatively heavy, when the glass fiber is used, the glass fiber itself is heavy as an inorganic material, and also the resin felt It is produced by impregnating a thermosetting resin such as a phenol resin in a common felt, thereby increasing the weight of the laminate itself. Therefore, when the conventional interior laminate having the base material layer 2 made of these materials is applied to a vehicle, there is a problem that the overall load of the vehicle is increased, resulting in a reduction in fuel efficiency.
또한, 종래의 내장재 적층체들이 유리섬유나 페이퍼보드가 기재층(2)으로 사용되기 때문에 충분한 방음성 및 내열성을 나타내기 위하여는 상당한 두께를 가져야 하므로 내장재 적층체 자체의 두께도 매우 두꺼워져서 이러한 종래의 내장재 적층체로 마감하였을 때 미려한 외관을 제공하지 못하는 문제점이 있었다.In addition, since the conventional interior laminates must have a considerable thickness in order to exhibit sufficient sound insulation and heat resistance since glass fibers or paper boards are used as the substrate layer 2, the thickness of the interior laminates is also very thick. When finishing with the interior laminate there was a problem that does not provide a beautiful appearance.
더욱이, 유리섬유는 그 제조, 취급 및 폐기의 전체 순환사이클에서 취급자에 진폐증을 유발하고, 먼지 등을 대량 생성하여 대기오염의 원인이 되며, 레진펠트 역시 소각처리시에 유동성가스를 다량 배출하여 공해를 일으키는 문제점이 있었으며, 이러한 모든 문제점들에도 불구하고 이러한 종래의 내장재 적층체의 사용은 방음성 및 내열성이 뛰어나지 못했으며, 더욱 단가가 높은 문제점을 가지고 있었다.Moreover, glass fiber causes pneumoconiosis in the handling cycle of the entire circulation cycle of its manufacture, handling and disposal, and creates a large amount of dust, causing air pollution. Resin felt also emits large amounts of liquid gas during incineration. In spite of all these problems, the use of such conventional interior laminates was not excellent in soundproofing and heat resistance, and had a higher cost.
따라서, 본 고안자는 전술한 종래의 내장재 적층체의 문제점을 해결하고자 본 고안을 착안하게 되었다.Therefore, the present inventors came to devise the present invention to solve the problems of the above-described conventional interior laminate.

본 고안의 다른 목적은, 유리섬유 등을 사용치 않고, 폴리우레탄폼과 화학단섬유로 된 혼성부직포를 적층하여 매우 가벼운 내장재 적층체를 제공함에 있다.Another object of the present invention is to provide a very light interior material laminate by laminating a hybrid nonwoven fabric made of polyurethane foam and chemical short fibers without using glass fibers or the like.
본 고안의 또다른 목적은, 고융점화학단섬유와 저융점화학단섬유를 혼합하여서 이루어진 혼성부직포를 사용하여 적층체의 성형시에 혼성부직포가 가열, 압축되어 성형되도록 하여 성형을 단순화시킨 내장재 적층체를 제공함에 있다.Another object of the present invention is to use a hybrid nonwoven fabric composed of a mixture of high melting point chemical short fibers and low melting point chemical short fibers to laminate a composite material to simplify the molding by heating, compressing and molding a hybrid nonwoven fabric when forming a laminate.
