More specifically, by pressing a three-dimensional pattern on a flat sound absorbing board, the sound absorbing board not only has a three-dimensional aesthetic, but also a sound absorbing power with dignity. An improved sound absorbing board is provided.
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 등 이 가능한 폴리에스터 섬유를 이용한 흡음재가 많이 사용되고 있다. 폴리에스터 흡음보드는 별도의 마감없이 사용되기도 하지만, 통상 패브릭(Fabric)으로 감싸서 마감하거나, 인쇄등의 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, many sound absorbing materials using polyester fibers, which are capable of excellent sound absorbing force, impact, and application alone, have been used. Polyester sound-absorbing board may be used without a separate finish, but is usually introduced to finish by wrapping with a fabric (Fabric), or using a method such as printing.
하지만, 이러한 방법은 모두 단순한 평면형태의 형상을 하고 있어서 입체적인 심미감을 주기에는 한계가 있다.However, all of these methods have a simple planar shape, so there is a limit to giving a three-dimensional aesthetic.
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 발명은 이러한 종래 기술의 문제점을 해결하기 위해 안출된 것으로, 폴리에스터 흡음보드에 있어서 패브릭 및 인쇄등의 방법으로 마감된 평면형태의 흡음보드를 입체적인 3차원 무늬를 프레스 성형하여 고품격의 흡음력이 향상된 흡음보드를 제공하는 것이다.Accordingly, the present invention has been made to solve the problems of the prior art, a high-quality sound absorbing power by pressing a three-dimensional three-dimensional pattern of the planar sound-absorbing board finished by a method such as fabric and printing in the polyester sound-absorbing board It is to provide an improved sound absorption board.
본 발명의 또다른 목적은, 상기의 고품격과 흡음력 향상 이외에 설치 장소 및 필요에 따라 입체형상의 디자인을 변경하여 동일소재를 사용하여 흡음력 및 음의 잔향시간등의 조절이 가능한 흡음보드를 제공하는 것이다.It is still another object of the present invention to provide a sound absorbing board capable of adjusting sound absorbing power and sound reverberation time using the same material by changing the design of the three-dimensional shape in addition to the high quality and sound absorbing power.
이러한 목적 달성을 위한 본 발명에 따른 입체형상을 갖는 성형 흡음보드는, 기본적으로 녹는점이 230~270℃의 범위를 갖는 폴리에스터 섬유와 녹는점이 90~180℃의 범위를 갖는 저융점 폴리에스터 섬유로 구성되며, 여기에 선택적으로 폴리프로필렌 섬유나 이종의 고분자재료가 동시에 복합방사되어 얻어지는 시스-코어형태의 섬유가 혼합되어 제조되는 흡음보드를 프레스 성형을 통하여 3차원적인 입체형상을 갖춘 형태로 이루어져 있다.Molded sound absorbing board having a three-dimensional shape according to the present invention for achieving this purpose is basically a polyester fiber having a melting point of 230 ~ 270 ℃ range and a low melting point polyester fiber having a melting point of 90 ~ 180 ℃ range It consists of a sound absorbing board made of a mixture of polypropylene fiber or a heterogeneous polymer material and the sheath-core fiber obtained by the simultaneous simultaneous spinning of a three-dimensional solid shape through press molding .
이하, 본 발명의 바람직한 실시예를 상세하게 설명하면,Hereinafter, the preferred embodiment of the present invention in detail,
먼저, 폴리에스터 섬유와 저융점 폴리에스터 섬유 원사를 사용용도 및 목적에 따라 소정의 배합비로 분섬 및 혼섬공정을 거친다. 바람직하게는 폴리에스터 섬유 30~70%, 저융점 폴리에스터 섬유 70~30% 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 얽히게 만들어 주는 니들 펀칭공정(Needle Punching)을 거쳐 부직포 형태의 복합매트를 제조한다. First, the polyester fiber and the low-melting polyester fiber yarn are subjected to the division and blending process at a predetermined blending ratio depending on the purpose of use and purpose. Preferably, the fiber is subjected to the spinning and blending at a ratio of 30 to 70% of the polyester fiber and 70 to 30% of the low melting point polyester 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. In order to improve the post-processing and strength of the laminated web, thousands of needles are reciprocated up and down to produce a non-woven composite mat through needle punching process in which the fibers of each layer are entangled with each other. do.
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 가격대비 흡음효과가 비효율적이다. 소정의 두께로 압착된 보드는, 냉각공정을 거쳐 일정한 크기로 재단된 다음, 다시 예열 및 프레싱(Pressing)공정을 거쳐 3차 원적인 입체 형상을 갖게 된다.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 of less than 3mm falls significantly, more than 30mm is inefficient due to the reduction of the interior space and cost-effective sound-absorbing effect due to the internal construction of the sound absorbing board. The board squeezed to a predetermined thickness is cut to a predetermined size through a cooling process, and then has a tertiary solid shape through a preheating and pressing process.
여기서, 통상 기존의 흡음보드는 제품의 흡음력 설계가 원사의 종류나 구성비, 제조조건 등에 의해서만 조절이 가능한데 비해, 본 발명을 통해 제조된 흡음보드는 3차원 입체형상 및 무늬에 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.Here, the conventional sound-absorbing board is a sound absorption power design of the product can be adjusted only by the type, composition ratio, manufacturing conditions, etc. of the yarn, the sound-absorbing board manufactured through the present invention according to the three-dimensional shape and pattern, product installation place and It is possible to design sound absorption and sound reverberation time according to the use, so that it is possible to design an optimal acoustic engineering space at a low cost while minimizing structural changes of existing buildings.
또한, 사용 용도 및 목적에 따라 프레싱 공정 이전에, 패브릭이나 인쇄 등의 공정을 거쳐 마감 제조된 흡음보드에 3차원 형상의 구조 및 무늬의 금형을 통해 예열 및 프레싱하여 입체형상의 흡음보드를 제조할 수 있으며, 방염 및 불연처리를 하여 제조할 수 있다.In addition, according to the purpose and purpose of use, a three-dimensional sound absorbing board can be manufactured by preheating and pressing through a three-dimensional structure and pattern mold on a sound absorbing board finished through a process such as fabric or printing prior to the pressing process. It can be produced by flame and flame retardant treatment.
