Description
본 고안은 폴리에스터 및 폴리프로필렌 등의 열가소성 단섬유가 주요 원료로 사용되어 제조된 흡음보드에 있어서, 제품의 외형에 심미감을 부여하기 위해 섬유용 에칭액을 사용하여 에칭처리하여 마감처리한 흡음보드에 관한 것으로, 좀 더 상세하게는 평면상의 흡음보드에 각종 문양이 에칭될 수 있도록 제작된 실크스크린이나 비교적 단순한 반복무늬가 새겨진 그라비아 롤(Roll) 등을 이용하여 에칭처리 함으로써, 평면상의 흡음보드가 갖지 못하는 입체적인 질감을 부여하게 되어, 품격과 함께 흡음력 또한 향상된 흡음보드에 관한 것이다.The present invention is a sound absorbing board manufactured by using thermoplastic short fibers such as polyester and polypropylene as the main raw materials, and is applied to the sound absorbing board which is finished by etching by using an etching solution for the fiber to give an aesthetic appearance to the product. In more detail, a flat screen sound absorbing board is etched by using a silk screen or a gravure roll engraved with a relatively simple repetitive pattern so that various patterns can be etched on the flat sound absorbing board. It gives a three-dimensional texture that can not, and the sound absorption as well as the sound absorbing board is improved.
산업이 발달하고 운송수단이 발달함에 따라, 인간의 주위환경 요소중에 소음원이 증가하게 되어, 이를 효율적으로 저감시킬 수 있는 방법이 여러 가지로 형태로 시도되고 있다. As the industry develops and the vehicle is developed, noise sources increase among human environmental factors, and various methods have been attempted to effectively reduce them.
근본적으로 소음을 저감시킬 수 있는 방법으로, 소음원에서 발생하는 소음을 저감시키는 방법과 소음원을 흡음재를 사용하여 외부로 소음이 전달되지 못하도록 하는 방법이 있다. 소음원에서 발생하는 소음을 줄이는 방법은 현실적으로 많은 어려움이 있어서, 소음원의 주위에 흡음재를 사용하는 방법이 많이 사용되고 있는 실정이다. 이렇게 사용되는 흡음재의 종류에는 크게 무기계와 유기계 재료가 사용되고 있는데, 무기계 재료로는 암면, 글라스 울, 유리섬유 등이 있고, 유기계 재료에는 폴리에스터 섬유를 이용하여 제조한 흡음보드, 우레탄, 폴리프로필렌, 폴리에틸렌등의 수지를 발포시킨 재료가 사용되고 있다. Fundamentally, there are methods for reducing noise, a method of reducing noise generated from a noise source, and a method of preventing noise from being transmitted to the outside using a sound absorbing material. The method of reducing the noise generated from the noise source has a lot of difficulties in reality, the method of using a sound absorbing material around the noise source is a situation that is used a lot. The types of sound absorbing materials used in this way are mainly inorganic and organic materials, and the inorganic materials include rock wool, glass wool, and glass fiber, and the organic materials include sound absorbing boards made of polyester fiber, urethane, polypropylene, The material which foamed resin, such as polyethylene, is used.
무기계 흡음재의 경우, 유기계 재료에 비해 상대적으로 가격이 저렴하고 흡음력 또한 우수하여 각종 건축물 및 선박 내장재등에 많이 사용되고 있다. 하지만, 제품 제조공정상 발생하는 각종 분진 등이 인체에 유해하여 작업자의 안전을 위협하는 요소를 갖고 있으며, 장기적인 사용시 수분 등에 취약하여 흡음 및 단열성능의 저하가 일어나는 단점이 있다. 유기계 흡음재중 폼(Foam)형태를 갖는 흡음재의 경우, 무기계 소재에 비해 가볍고 내수성이 우수한 장점이 있으나, 단독으로 사용하기 어렵고 충격에 약한 단점이 있다. 이에 반해, 우수한 흡음력과 충격 및 단독적용 등이 가능한 폴리에스터 섬유를 이용한 흡음재가 많이 사용되고 있다. 폴리에스터 흡음보드는 별도의 마감없이 사용되기도 하지만, 통상 패브릭(Fabric)으로 감싸서 마감하거나, UV 인쇄 등의 방법을 이용하여 마감하는 방법이 소개되고 있다.In the case of inorganic sound absorbing materials, it is relatively inexpensive and has excellent sound absorbing power compared to organic materials, and is widely used in various buildings and ship interior materials. However, various dusts generated in the product manufacturing process are harmful to the human body and thus have a threat to the safety of the worker. The long-term use is vulnerable to moisture and the like, resulting in a decrease in sound absorption and insulation performance. In the case of the sound absorbing material having a foam (foam) form of the organic sound absorbing material, there is an advantage in light and excellent water resistance compared to the inorganic material, it is difficult to use alone and has a weak disadvantage in impact. On the other hand, the sound absorption material using the polyester fiber which is excellent in sound absorption power, an impact, and can apply independently is used a lot. Polyester sound-absorbing board may be used without a separate finish, but a method of finishing by wrapping with a fabric (Fabric), or by using a UV printing method has been introduced.
패브릭으로 마감하여 제조한 흡음보드의 경우, 패브릭 소재가 갖는 포근함과 자연스러운 느낌을 주지만, 기존 흡음보드에 패브릭 소재를 감싸는 공정과 접착제 등을 사용하여 이를 고정시키는 공정이 필요하게 된다. In the case of a sound absorbing board manufactured by finishing the fabric, the fabric material gives the warmth and natural feeling, but a process of wrapping the fabric material on the existing sound absorbing board and fixing it by using an adhesive or the like is required.
한편, 대한민국 등록특허 10-0398507호에는 견면 또는 저밀도 섬유판재를 부직포 및 직포로 덮어씌운 상태로 가열판식 핫프레스에 투입하여 가열, 압축하고, 냉각하는 것을 특징으로 하는 섬유판재가 제시되어 있으나, 이 경우 역시 단순한 평면형태의 섬유판재를 제공함으로써 고품격의 흡음재로 사용하기에는 한계가 있으며, 시공장소에 따른 흡음율의 조절이 초기 원료 배합비 및 가공조건 조정으로만 가능하기 때문에 설계상의 자유도가 제한적이다.On the other hand, Korean Patent No. 10-0398507 discloses a fiberboard material characterized in that the heating or compressing and cooling by putting in a hot plate type hot press in a state covered with a plush or low density fiberboard material, but this In the case of providing a simple planar fiber board, there is a limit to use as a high-quality sound absorbing material, and the design of the sound absorption rate is limited only by adjusting the initial raw material blending ratio and processing conditions according to the factory.
따라서, 본 고안은 이러한 종래 기술의 문제점을 해결하기 위해 안출된 것으로, 폴리에스터 및 폴리프로필렌 등의 열가소성 단섬유가 주요 원료로 사용되어 제조된 흡음보드에 있어서, 에칭공정에 의해 입체형상의 무늬를 갖는 흡음보드를 제공함으로써, 패브릭 마감 등의 추가공정 필요없이, 다양한 형태의 입체적인 문양을 갖는 고품격 흡음보드를 제공하는 것이며, 고품격의 흡음보드를 보다 저렴한 가격으로 공급하고, 고객의 요구와 시장의 변화에 빠르게 대응할 수 있는 흡음보드를 제공하는 것이다.Accordingly, the present invention has been devised to solve the problems of the prior art, and in a sound absorbing board manufactured by using thermoplastic short fibers such as polyester and polypropylene as the main raw materials, having a three-dimensional pattern by an etching process By providing the sound absorbing board, it is to provide high quality sound absorbing boards with various shapes and three-dimensional patterns without the need for additional process such as fabric finishing, supply high quality sound absorbing boards at a lower price, and to meet customer demands and market changes. It is to provide a sound absorbing board that can respond quickly.
본 고안의 또다른 목적은, 상기의 고품격과 흡음력 향상 이외에 설치 장소 및 필요에 따라 에칭되는 입체형상의 디자인을 다양하게 변경하고 에칭되는 깊이를 조절하여 동일소재를 사용하면서도, 흡음력 및 음의 잔향시간등의 설계요소를 간편하면서도 저렴한 비용으로 반영할 수 있는 흡음보드를 제공하는 것이다.Another object of the present invention, in addition to the above-mentioned high-quality and sound-absorbing power improvement, the design of the three-dimensional shape to be etched in accordance with the installation place and needs are variously changed and the depth of the etching is adjusted to use the same material, sound absorption and sound reverberation time, etc. It is to provide a sound absorption board that can reflect the design elements of the simple and low cost.
이러한 목적 달성을 위한 본 고안에 따른 에칭공정에 의한 기능성 흡음보드는, 기본적으로 녹는점이 230~270℃의 범위를 갖는 폴리에스터 섬유와 녹는점이 90~180℃의 범위를 갖는 저융점 폴리에스터 섬유 또는 녹는점이 140~170℃의 범위를 갖는 폴리프로필렌 섬유로 구성되며, 여기에 선택적으로 폴리프로필렌 섬유나 이종의 고분자재료가 동시에 복합방사되어 얻어지는 시스-코어형태의 섬유 또는 융점이 각기 다른 섬유가 동시에 복합방사되어 제조되는 콘쥬게이티드 형태의 섬유가 혼합되어 제조되는 흡음보드의 일면에 각종 문양이 에칭 될 수 있도록 제작된 실크스크린이나 비교적 단순한 반복무늬가 새겨진 그라비아 롤 등을 이용하여 무늬를 에칭시켜 형상화한 형태로 이루어져 있다.Functional sound-absorbing board by the etching process according to the present invention for achieving this purpose, the polyester fiber having a melting point of 230 ~ 270 ℃ range and low melting point polyester fiber having a melting point of 90 ~ 180 ℃ range or It is composed of polypropylene fiber with melting point in the range of 140 ~ 170 ℃, and sheath-core fiber or fiber with different melting points is obtained by selectively spinning together polypropylene fiber or different polymer materials. A pattern is etched by using a silk screen or a gravure roll engraved with a relatively simple repetitive pattern so that various patterns can be etched on one surface of a sound absorbing board manufactured by spinning conjugated fibers. It consists of forms.
이하, 본 고안의 바람직한 실시예를 상세하게 설명하면,Hereinafter, the preferred embodiment of the present invention in detail,
먼저, 폴리에스터 섬유와 저융점 폴리에스터 섬유 원사 또는 폴리프로필렌 섬유를 사용용도 및 목적에 따라 소정의 배합비로 분섬 및 혼섬공정을 거친다. 바람직하게는 폴리에스터 섬유 20~80%와 저융점 폴리에스터 섬유 80~20% 또는 폴리프로필렌 섬유 80~20% 의 비율로 분섬 및 혼섬공정을 거친다. 이렇게 분섬 및 혼섬된 섬유는 에어(Air) 이송을 통하여 카딩공정(Carding)으로 옮겨져 일정한 두께의 얇은 시트형태로 적층시킨다. 이렇게 적층된 웹을 후가공 및 강도 등의 증진을 위해 수천 본의 바늘이 상하 왕복운동하여, 적층된 각각의 층의 섬유들이 서로 물리적으로 얽히게 만들어 주는 니들 펀칭공정(Needle Punching)을 거쳐, 부직포 형태의 복합매트를 제조한다. First, the polyester fiber and the low-melting polyester fiber yarn or polypropylene fiber are subjected to the splitting and blending process at a predetermined compounding ratio according to the use and purpose. Preferably, the fiber is subjected to the spinning and blending at a ratio of 20 to 80% of polyester fiber and 80 to 20% of low melting polyester fiber or 80 to 20% of polypropylene fiber. These divided and mixed fibers are transferred to a carding process through air transfer and stacked in a thin sheet form having a constant thickness. Thousands of needles are reciprocated up and down to improve the post-processing and strength of the laminated web. Through needle punching process, the fibers of each layer are entangled with each other. Prepare a composite mat.
이렇게 제조된 복합매트를 예열공정을 거친 다음, 다수의 가압롤을 통과시켜 소정의 두께로 압착한다. 바람직하게는 3~30mm의 두께가 적절하다. 3mm이하는 흡음력이 현저히 떨어지게 되고, 30mm이상은 흡음보드의 내부시공에 따른 실내공간의 축소 및 가격 상승 대비 흡음효과 상승이 많지 않아 비효율적이다. 소정의 두께로 압착된 보드는, 냉각공정을 거쳐 일정한 크기로 재단된 다음, 소정의 문양이 도안된 실크스크린이나 인쇄 롤에 에칭액을 통과시킨 후, 고온에서 소정의 시간동안 방치하고 수세 및 건조공정을 거쳐서, 다양한 형태의 문양이 에칭된 흡음보드로 제조된다.The composite mat thus prepared is subjected to a preheating process, and then pressed through a plurality of pressure rolls to a predetermined thickness. Preferably a thickness of 3 to 30 mm is appropriate. Sound absorption is less than 3mm significantly, and more than 30mm is inefficient because of the reduction of the interior space due to the internal construction of the sound absorbing board and the increase in sound absorption effect compared to the price increase. The board pressed to a predetermined thickness is cut to a predetermined size through a cooling process, and then passed through an etching solution through a silk screen or printing roll with a predetermined pattern, and then left at a high temperature for a predetermined time and washed with water and dried. Through the, various forms of patterns are manufactured by etching the sound absorbing board.
여기서, 통상 기존의 흡음보드는 단색의 제품이 주로 사용되고 있는데, 필요에 따라 이종의 색상을 갖는 부직포를 합지하여 가열 압착함으로써, 상면과 하면의 색상이 다른 흡음보드를 제조할 수 있다. 이렇게 제조된 흡음보드에 에칭공정을 하게되면 상면의 에칭된 부분에 하면의 색상이 드러나게 됨으로써, 좀 더 고급스럽고, 에칭 무늬를 시각적으로 선명하게 나타낼 수 있을 뿐 아니라, 상면과 하면의 성분 배합비를 다르게 설계하게 되면, 흡음율의 조절이 가능한 흡음보드를 제조할 수 있게 된다. Here, in general, the existing sound absorbing board is mainly used a single color of the product, if necessary, by laminating a non-woven fabric having a different color of the heat-compression, it is possible to manufacture a sound absorbing board having a different color of the upper and lower surfaces. When the etching process is performed on the sound absorbing board manufactured as described above, the color of the lower surface is revealed on the etched portion of the upper surface, so that the color of the upper surface and the lower surface of the upper and lower surfaces can be different. By designing, it is possible to manufacture a sound absorbing board capable of adjusting the sound absorption rate.
또한, 기존의 흡음보드는 흡음력의 설계가 원사의 종류나 구성비, 제조조건, 두께 등에 의해서만 조절이 가능한데 비해, 본 고안을 통해 제조된 흡음보드는 에칭되는 무늬의 입체형상 및 에칭 깊이에 따라서, 제품 설치장소 및 용도에 맞게 흡음력 및 음의 잔향시간 등의 설계가 가능하여 기존 건축물의 구조적인 변경을 최소화하면서도 저렴한 비용으로 최적의 음향공학적인 공간의 설계가 가능하다.In addition, while the existing sound absorbing boards can be controlled only by the type, composition ratio, manufacturing conditions, thickness, etc. of the sound-absorbing force design, the sound absorbing boards manufactured according to the present invention are manufactured according to the three-dimensional shape and the etching depth of the pattern to be etched. It is possible to design sound absorption and sound reverberation time according to the installation location and use, and it is possible to design the optimal acoustic engineering space at a low cost while minimizing the structural change of existing buildings.
또한, 사용 용도 및 목적에 따라 에칭공정 이전 또는 이후에, 인쇄, 방염, 불연처리를 하여 제조할 수 있다.In addition, depending on the purpose and purpose of use, it may be produced by printing, flameproofing, or nonflammable treatment before or after the etching process.
