Description

흡음패널 및 그 제조방법{Sound-absorbing Panel and Manufacturing Method Thereof}Sound-absorbing panel and manufacturing method Thereof}

본 발명은 흡음패널 및 그 제조방법에 관한 것으로, 더욱 상세하게는 원목의 양면에 각각 소리 또는 소음을 완화시키는 흡음부를 형성하여 건물 또는 실내에서 발생되는 소리를 흡음시킴은 물론 피톤치드 원목을 이용하여 건물 또는 실내에 유익한 향기를 제공할 수 있도록 하는 흡음패널 및 그 제조방법에 관한 것이다.The present invention relates to a sound absorbing panel and a method of manufacturing the same. More specifically, the sound absorbing part is formed on both sides of the wood to reduce the sound or noise, respectively, to absorb sound generated in the building or the room, as well as the building using phytoncide wood. Or to a sound absorbing panel and a method for producing the same that can provide a beneficial fragrance indoors.

일반적으로 흡음패널은 극장, 음악실, 녹음실, 연주회장 등에는 소음이 외부로 전달되거나 외부의 소리가 유입되는 것을 차단하고, 소리에 의한 음향이 반사되어 발생되는 공진현상으로 인한 소리의 불쾌감을 제거하기 위해 흡음 및 방음 설비를 갖추고 있으며, 아이들이 많은 일반 가정에서도 실내의 소음이 외부로 전달되지 않도록 흡음 및 방음 설비를 설치한다.In general, the sound absorbing panel prevents noise from being transmitted to the outside or the outside of the sound in the theater, music room, recording room, concert hall, etc., and removes the discomfort of the sound caused by the resonance caused by the reflection of the sound. It is equipped with sound absorbing and soundproofing facilities, and sound-proofing and soundproofing facilities are installed so that indoor noise is not transmitted to the outside even in homes with many children.

이러한 흡음 및 방음 설비는 소음원의 주위에 흡음재를 사용하는 방법이 많이 사용되는데, 이렇게 사용되는 흡음재의 종류에는 크게 무기계와 유기계 재료가 사용되고 있으며, 무기계 재료로는 암면, 글라스 울, 유리섬유 등이 있고, 유기계 재료에는 폴리에스터 섬유를 이용하여 제조한 흡음보드, 우레탄, 폴리프로필렌, 폴리에틸렌 등의 수지를 발포시킨 재료가 사용되고 있다.The sound absorbing and soundproofing equipment is used a lot of methods using a sound absorbing material around the noise source, and the type of sound absorbing material used in this way is largely used inorganic and organic materials, inorganic materials include rock wool, glass wool, glass fiber, etc. As the organic material, a material obtained by foaming a resin such as a sound absorbing board made of polyester fiber, urethane, polypropylene, polyethylene, or the like is used.

한편 주택이나 빌딩 등의 건축물에는 다양한 내장재와 외장재 등의 건축자재가 사용되고 있으며, 최근 기술수준의 향상과 더불어 다양한 재질의 자재가 사용되고 있다 할 수 있으나 아직까지는 실내 마감재나 인테리어 자재 등으로 목질계 자재의 사용이 많음은 부인할 수 없다 할 것이다.On the other hand, various building materials such as interior materials and exterior materials are used for buildings such as houses and buildings, and various materials have been used in recent years with the improvement of the technical level. However, until now, wood finishing materials have been used as interior finishing materials or interior materials. The use will be undeniable.

이러한 목질계 자재는 현재 대부분이 패널 형태로 제작 및 보급되고 있으며, 여기에는 원목이나 중밀도섬유판(MDF), 고밀도섬유판(HDF), 파티클보드(PB), 멜라민보드, 합판, 강화목재 등을 그 예로 들 수 있다.Most of these wood-based materials are manufactured and distributed in the form of panels, including solid wood, medium density fiberboard (MDF), high density fiberboard (HDF), particle board (PB), melamine board, plywood, and reinforced wood. For example.

하지만 상술한 목질계 자재는 단열성을 구비한다 할 수 있으나, 흡음성이 떨어지는 단점을 가지고 있는 것으로서, 당해 산업분야에서는 목질계 자재를 사용하면서도 흡음성을 개선하기 위한 시도 및 연구개발이 활발히 수행되고 있다.However, the above-described wood-based material may be provided with thermal insulation, but has a disadvantage in that sound absorption is poor. In the industrial field, attempts and research and development for improving sound-absorbance while using wood-based materials have been actively performed.

이와 같은 당해 산업분야에서의 시도 및 연구개발은 최근 생활수준의 향상과도 밀접한 관련이 있으며, 즉 쾌적한 문화생활의 요구에 기인하고 있다 할 수 있다.Such attempts and R & D in this industrial field are closely related to the recent improvement of living standards, that is, it can be attributed to the demand for pleasant cultural life.

부연하면, 쾌적한 문화생활의 요구에 따라 건축물의 음향 설계에 대한 중요성이 대두되고 있으며, 특히 연주회장이나 공연장 등 대중이 이용하는 공공의 장소에 있어서는 방음시설이 필수적으로 구비되어야 한다.In other words, the importance of sound design of buildings has emerged in accordance with the demands of pleasant cultural life, and in particular, soundproofing facilities must be provided in public places used by the public, such as concert halls and performance halls.

최근에는 아파트와 같은 주거용 공동 주택에 있어서도 소음에 의한 민원 발생이 많아지고 있다.In recent years, the number of civil complaints caused by noise has also increased in residential multi-family houses such as apartments.

한편 종래 일반적으로 사용되고 있는 흡음패널을 살펴보면, 암면이나 유리면과 같은 판상의 무기섬유판재 위에 일반직물을 피복한 것을 사용하거나 판이나 중밀도섬유판(MDF) 등의 판재 표면에 다수의 구멍을 타공함으로써 흡음기능을 발휘하도록 하고 있다.On the other hand, in the conventional sound absorbing panels, sound absorbing is obtained by coating a general fabric on a plate-like inorganic fiber sheet such as rock wool or glass, or drilling a plurality of holes in a plate or surface of a plate such as a medium density fiber board (MDF). To function.

하지만 종래 사용되고 있는 이와 같은 흡음패널의 타공이 갖는 흡음성은 다수의 타공들이 일방향성으로 형성되므로, 다방향성의 역학적 움직임을 갖는 소리를 제대로 흡음 처리하는데 그 기능성이 떨어지는 단점을 가지고 있다.However, the sound absorbing property of the perforations of the sound absorbing panel used in the prior art has a disadvantage in that its functionality is poor in properly absorbing sound having a multidirectional mechanical movement because a plurality of perforations are formed in one direction.

더불어 종래에는 목재판재의 표면에 다수의 타공에 의한 흡음공을 형성시킨 흡음패널이 많이 사용되고 있다 할 것인데, 이는 흡음성이 그다지 뛰어나지 않을 뿐더러 설치되는 장소 및 공간에 따른 흡음기능에 차이를 나타내고 있다.In addition, in the prior art, the sound absorbing panel in which a plurality of sound-absorbing holes are formed on the surface of the wood board is used a lot, which is not very excellent sound absorption, and also shows a difference in the sound absorbing function according to the installation place and space.

이로 인해 흡음패널 시공자 또는 인테리어업자 등은 설치 장소별 또는 적용 공간별 차이에 따른 흡음의 기능성을 높여주고 효율적인 활용을 위해 흡음패널을 벽면이나 천장 등에 설치 시 흡음패널 자체를 기울여서 경사지게 설치하거나 기울기 각도를 각각 다르게 하여 설치하는 경우가 있다.Accordingly, the sound absorbing panel builder or the interior contractor can install the slanted panel by tilting the sound absorbing panel itself when installing the sound absorbing panel on the wall or the ceiling to improve the sound absorbing function according to the difference between the installation place or the application space, and to adjust the tilt angle. Each may be installed differently.

그런데 흡음패널 자체를 기울여서 경사지게 설치하거나 기울기 각도를 각각 다르게 하여 설치하는 것은 이를 지지하기 위한 지지구조물이나 보강구조물이 요구되는 등 작업에 불편함이 있을 뿐만 아니라 설치 후 안전성 확보를 위해 보다 신중하고 견고한 작업이 요구되는 등 어려움이 있으며, 때론 흡음패널을 포함하는 구조물이 쉽게 무너질 수 있는 등 안전사고가 발생할 우려가 그만큼 높다 할 수 있다.However, inclining the sound absorbing panel itself or installing it at different inclination angles is not only inconvenient to work such as requiring a support structure or a reinforcing structure to support it, but also more careful and robust work to secure safety after installation. There is a difficulty such as required, and sometimes there is a high risk of a safety accident such as the structure including the sound absorbing panel can be easily collapsed.
