Description
본 발명은 공명 구조가 구비된 소음방지용 발포 알루미늄 패널에 관한 것으로, 더욱 상세하게는 오픈된 기포를 구비한 발포 알루미늄을 가공하여 공명용 공간을 형성하여 고도의 흡음성을 요하는 방음재로 사용할 수 있도록 한 공명 구조가 구비된 소음방지용 발포 알우미늄 패널에 관한 것이다.The present invention relates to a noise-resistant foamed aluminum panel provided with a resonance structure, and more particularly to forming a space for resonance by processing the foamed aluminum having an open bubble so that it can be used as a sound-proofing material that requires high sound absorption. The present invention relates to a noise preventing expanded aluminum panel provided with a resonance structure.
일상 주변에는 각종 기계 설비의 가동, 자동차, 철도, 지하철, 항공기 등 교통 수단의 운행, 중장비를 이용한 각종 공사 또는 각종 음향 기기의 작동 등 여러 가지 요인에 의해 바람직하지 않은 소리, 즉 소음이 발생되기 마련이다. 이런 소음은 개인적으로는 난청, 두통, 불안감 등을 유발하여 건강을 해치는 요인으로 작용하고, 산업 현장에서는 열악한 작업환경을 조성하고 진동을 발생시켜 생산성의 저하와 제품의 품질저하를 야기한다. 따라서, 소음 유발원들은 가능한 한 적은 소음이 발생되도록 설계되어야 하고, 불가피하게 발생된 소음이라면 가능한 한 소음이 외부로 전파되는 것을 차단하는 조치가 필요하다.In everyday life, undesired sounds, ie noises, are generated by various factors such as the operation of various mechanical equipment, the operation of transportation means such as automobiles, railways, subways, aircrafts, the construction of heavy equipment, or the operation of various acoustic devices. to be. These noises personally cause hearing loss, headaches, anxiety, etc., and cause harm to health, and in an industrial site, create a poor working environment and generate vibrations, resulting in deterioration of productivity and product quality. Therefore, the noise sources should be designed to generate as little noise as possible, and if the noise is inevitably generated, measures should be taken to prevent the noise from propagating outside.
이런 방음의 필요성은 작업장, 도로변, 철도변, 공항주변, 건설현장, 중장비, 아파트나 사무실과 같은 공동 주거시설, 음악당이나 극장과 같은 공연장, 실내스포츠 시설 및 각종 위락시설과 같은 거의 모든 주변 생활환경에 요구되고 있다.The necessity of sound insulation is almost all around the living environment, such as workplaces, roadsides, railways, airports, construction sites, heavy equipment, communal dwellings such as apartments or offices, concert halls or theaters, indoor sports facilities and various recreational facilities. Is required.
통상적인 방음 방법으로서는 흡음 또는 차음 성능이 있는 소재로 만들어진 각종 방음재를 사용하여 방음벽, 방음 칸막이(partition), 방음실, 음향처리용 마감재 등과 같은 방음 구조물을 설치하므로써 소음을 흡수하고 그 전파 경로를 차단하는 방법이 널리 사용되고 있다.As a conventional soundproofing method, various soundproofing materials made of sound absorbing or soundproofing materials are used to install soundproofing structures such as soundproof walls, partitions, soundproof rooms, and finishing materials for sound treatment, and to block the propagation path. The method is widely used.
일반적으로 널리 사용되고 있는 방음 소재로서는 목재 또는 콘크리트와 같은 일반적인 건축 소재, 폴리우레탄, 폴리에틸렌 또는 폴리에스터와 같은 합성수지재, 글래스울 또는 암면과 같은 무기 섬유재 및 금속 타공판과 같은 금속재 등 여러 가지 소재를 단독 또는 복합한 것들을 들 수 있다.In general, the soundproofing materials widely used include various materials such as general building materials such as wood or concrete, synthetic resin materials such as polyurethane, polyethylene or polyester, inorganic fiber materials such as glass wool or rock wool, and metal materials such as metal perforated plates. Or combinations thereof.
방음재는 그 사용 장소와 용도에 따라 다소 차이는 있겠지만 광범위한 주파수 영역에서의 우수한 흡차음성 우수한 기계적 특성(내구성 등) 및 열적 특성(불연성, 난연성 등)을 구비하면서도 제조 원가가 저렴하고 시공이 간편한 것이 바람직할 것이다.The sound insulation material may vary depending on the place of use and use, but it is desirable to have low manufacturing cost and ease of construction while having excellent sound absorption and sound resistance in a wide frequency range, excellent mechanical properties (durability, etc.) and thermal properties (non-flammability, flame retardancy, etc.). something to do.
그러나, 종래의 방음재들은 상기한 여러 가지 요건들 중 일부의 요건에 부합하지 못하여 방음 설비의 구축에 이들을 적용함에 있어서 상당한 문제점들을 내포하고 있다. 예를 들어 목재나 플라스틱 수지로 된 방음재는 열에 약하여 화재에 취약하다는 문제점이 있고, 글래스울이나 암면 등은 환경 오염의 원인으로 작용하는 문제점이 있으며 알루미늄판은 자체의 소음 방지 성능이 충분하지 못하다는 한계가 있다. 또한 금속재를 제외한 종래의 방음재는 거의 재활용이 불가능하여 많은 쓰레기를 발생시키고 있다.However, conventional sound insulation materials do not meet the requirements of some of the various requirements described above and present significant problems in applying them to the construction of sound insulation facilities. For example, soundproofing materials made of wood or plastic resin are weak to heat and vulnerable to fire. Glass wool and rock wool have the problem of causing environmental pollution, and aluminum plates have insufficient noise prevention performance. There is a limit. In addition, conventional soundproofing materials other than metal materials are almost impossible to recycle, generating a lot of garbage.
한편, 음악당, 콘서트홀, 공연장, 극장, 방송국 스튜디오 등과 같은 음향 건축물의 경우에는 고도의 소음 방지성능을 가지는 건축 음향 설계가 되어야 하고, 따라서 소음이 외부로 방출되는 것을 방지하는 것뿐만 아니라 실내에서의 소리 반사, 잔향, 음의 분포, 확산 등을 적절히 조절하여 최적의 음향이 형성되도록 하여야 하는 바, 이를 위해서는 일차적으로 고도의 흡음 성능을 가지는 방음재가 적절히 사용되어야 한다.Meanwhile, in the case of acoustic buildings such as music halls, concert halls, performance halls, theaters, broadcasting studios, etc., a sound design having a high level of noise protection should be provided. Therefore, not only noise is prevented from being emitted to the outside, but also indoor sound. The reflection, reverberation, distribution of sound, diffusion, etc. should be properly adjusted to form an optimal sound. For this purpose, a soundproof material having a high sound absorption performance should be used properly.
본 발명의 목적은 소음방지 성능이 탁월하여 일반 방음재로 뿐만 아니라 음향처리를 요하는 건축물에 적용할 수 있고, 재활용이 가능하며 반영구적인 수명을 가지는 불연성, 초경량의 소음방지재를 제공하는 것이다.An object of the present invention is to provide a non-combustible, ultra-light weight noise protection material that can be applied to buildings that require sound treatment as well as general soundproofing material with excellent noise prevention performance, and is recyclable and has a semi-permanent life.

본 발명의 목적은 오픈된 기포를 구비한 발포 알루미늄 패널을 가공하고 여기에 규칙적으로 공명용 공간을 형성하여 고도의 흡음 성능을 가지도록 하므로써 달성된다.The object of the present invention is achieved by processing a foamed aluminum panel with open bubbles and having a resonant space therein regularly to have a high sound absorption performance.
또한, 본 발명의 목적은 발포 가공된 발포 알루미늄을 압연하여 폐쇄된 기포를 오픈된 기포로 변환시켜 제조한 오픈된 기포를 구비한 발포 알루미늄 패널의 두께 내에 폭방향의 공명용 공간이 규칙적으로 형성되어 있는 공명 구조가 구비된 소음방지용 발포 알루미늄 패널에 의해 달성된다.In addition, an object of the present invention is to form a resonant space in the width direction regularly in the thickness of the foamed aluminum panel having an open bubble prepared by rolling the foamed foamed foamed aluminum to convert the closed bubble into an open bubble Is achieved by an anti-foam foamed aluminum panel equipped with a resonant structure.
본 발명에 따른 공명 구조가 구비된 소음방지용 발포 알루미늄 패널에 기재로 사용되는 다수의 오픈된 기포를 가지는 발포 알루미늄 패널은 알루미늄을 발포 가공하여 다수의 오픈된 기포를 형성시킨 것이다. 오픈된 기포를 구비한 발포 알루미늄 패널은, 히터와 교반기가 구비된 주형에 알루미늄 금속을 넣어 용융하고, 증점제(viscosity increasing agent)를 투입하여 적정 점도를 유지한 다음 발포제를 첨가하여 기포를 형성시키는 공지의 알루미늄 발포 공정으로 발포 알루미늄을 제조한 후에 이 발포 알루미늄을 압연하여 폐쇄 상태의 기포를 오픈된 기포로 변환시키는 방법으로 제조한다.The foamed aluminum panel having a plurality of open bubbles used as a substrate in the noise-proof foamed aluminum panel provided with a resonance structure according to the present invention is formed by foaming aluminum to form a plurality of open bubbles. The foamed aluminum panel with open bubbles is known to melt by putting aluminum metal into a mold equipped with a heater and a stirrer, adding a thickening agent to maintain a proper viscosity, and then adding a blowing agent to form bubbles. After foaming aluminum is manufactured by the aluminum foaming process of this, this foamed aluminum is rolled and manufactured by the method of converting a bubble of a closed state into an open bubble.
여기에서 "오픈된 기포"의 의미는 발포 알루미늄에 형성되어 있는 기포들이 폐쇄되어 있는 것이 아니라 개방되어 있음을 의미한다. 통상적인 방법에 의해 제조되는 발포 알루미늄의 기포는 대부분이 폐쇄되어 각각의 기포가 하나의 밀폐공간을 형성하고 있다. 폐공간의 기포를 가지는 발포 알루미늄은 기포가 음파를 흡수하는 작용을 충분히 발휘하지 못하기 때문에 본 발명이 목적하는 충분한 방음 성능을 나타내지 못한다. 따라서, 본 발명에서는 발포 알루미늄을 압연기로 가볍게 압연하므로써 폐쇄된 기포를 터트려서 오픈된(개방된) 기포로 변환시키는 것이다.The term "open bubble" here means that the bubbles formed in the foamed aluminum are open rather than closed. Most of the bubbles of foamed aluminum produced by conventional methods are closed so that each bubble forms a closed space. Foamed aluminum having bubbles in the closed space does not exhibit sufficient sound insulation performance for the purpose of the present invention because bubbles do not sufficiently exhibit the effect of absorbing sound waves. Therefore, in the present invention, the foamed aluminum is lightly rolled by a rolling mill to burst the closed bubbles and convert them into open (open) bubbles.
발포 알루미늄을 압연하여 폐쇄 상태의 기포를 오픈된 기포로 변환시키는 것은 예를 들어 폐쇄된 기포를 가지는 발포 알루미늄 패널을 그 두께가 20-30%로 감축될 정도로 발포 알루미늄을 두께 방향으로 가압하므로써 이루어진다. 압연량(rolling reduction)은 발포 알루미늄 패널의 용도, 두께 등에 따라 적절히 조절할 수 있으며 다만 지나치게 압연량을 크게 함으로써 기포가 압착되어 없어지지 않도록 하여야 한다. 이렇게 제조된 발포 알루미늄 패널은 오픈된 기포를 다수 포함하는 다공질이 되며 총체적의 90%이상이 기포로 된 초경량의 흡음 패널이 된다.Rolling the foamed aluminum to convert the closed bubbles into open bubbles is achieved, for example, by pressing the foamed aluminum panel in the thickness direction such that the foamed aluminum panel having the closed bubbles is reduced to 20-30% in thickness. Rolling reduction can be appropriately adjusted according to the use, thickness, etc. of the foamed aluminum panel. However, by increasing the rolling amount excessively, bubbles should not be compressed and eliminated. The foamed aluminum panel thus manufactured is porous, including a large number of open bubbles, and more than 90% of the total volume becomes an ultra-light absorption panel made of bubbles.
이하, 첨부 도면을 참조하여 본 발명에 따른 공명 구조가 구비된 소음방지용 발포 알루미늄 패널을 구체적으로 설명한다. 이하의 구체예는 본 발명에 따른 공명 구조가 구비된 소음방지용 발포 알루미늄 패널을 예시적으로 설명하는 것일 뿐 본 발명의 범위를 제한하는 것이 아니다.Hereinafter, with reference to the accompanying drawings will be described in detail a foamed aluminum panel for noise prevention provided with a resonance structure according to the present invention. The following specific examples are merely illustrative of the anti-foam foamed aluminum panel provided with a resonance structure according to the present invention is not intended to limit the scope of the present invention.

As shown, the noise-proof foamed aluminum panel 1b having a resonance structure has a width in the width direction in the foamed aluminum panel 10 having the open bubbles 12 formed in a predetermined width, length, and thickness. 40) has a configuration formed so as to penetrate regularly.
오픈된 기포(12)가 구비된 발포 알루미늄 패널(10)은 음향 건축의 벽이나 천장 등에 조립식으로 설치할 수 있도록 규격화된 폭, 길이, 및 두께를 가지도록 형성되며 대체로 길이가 긴 형상으로 제작된다.The foamed aluminum panel 10 provided with the open bubbles 12 is formed to have a width, a length, and a thickness standardized to be prefabricated to a wall or a ceiling of an acoustic building, and is manufactured in a generally long shape.
발포 알루미늄 패널(10)의 두께 내에 공명용 공간(40)을 형성하기 위해서는 도 1에 도시된 바와 같이 동일한 사이즈의 두 개의 발포 알루미늄 패널(10) 사이에 동일한 사이즈의 다수의 바 형상의 가로부재(42)를 폭방향으로 규칙적으로 삽입하여 접착제로 접합하므로써 두 발포 알루미늄 패널(10)과 다수의 가로부재(42)에 의해 규정되는 공간이 공명용 공간(40)으로 되도록 한다.In order to form the resonance space 40 within the thickness of the foamed aluminum panel 10, a plurality of bar-shaped horizontal members having the same size between two foamed aluminum panels 10 of the same size as shown in FIG. 42 is regularly inserted in the width direction and bonded with an adhesive so that the space defined by the two foamed aluminum panels 10 and the plurality of horizontal members 42 is the resonance space 40.
그리고, 도 2에 도시된 바와 같이 발포 알루미늄 패널(10)을 소정의 길이와 폭 및 두께를 가지도록 형성한 후 솔리드한 두께 내에 일정한 간격으로 폭방향의 관통 공간(40)을 천공 가공하여 제작할 수도 있다. 상기 공간(40)은 사각형, 삼각형 또는 원형 등으로 형성할 수 있다.In addition, as shown in FIG. 2, the foamed aluminum panel 10 may be formed to have a predetermined length, width, and thickness, and then may be manufactured by drilling the through space 40 in the width direction at regular intervals within a solid thickness. have. The space 40 may be formed in a quadrangle, triangle, or circle.
공명용 공간(40)에는 한 칸씩 내지 세 칸씩 걸러서 패널(10)의 폭방향으로 관통된 슬릿(44)을 형성할 수 있으며 상기 슬릿(44)은 중고주파 공명음을 감소시키는 작용을 한다. 이와 같은 구조에 따라 음파가 패널(10)에 부딪치면서 상기 오픈된 기포(12)에 가해지면 기포(12)를 통과하면서 저주파 음이 감쇄되고, 슬릿(44)이 형성된 공명용 공간(40)의 공명 작용에 의해 중고주파 소음을 흡수하게 되므로 광범위한 주파수 영역에서의 소음 방지 효과가 탁월하다.In the resonance space 40, the slits 44 penetrated in the width direction of the panel 10 may be formed by filtering one to three squares, and the slits 44 serve to reduce the high frequency resonance sound. According to such a structure, when the sound wave strikes the panel 10 and is applied to the open bubble 12, the low frequency sound is attenuated while passing through the bubble 12, and the slit 44 of the resonance space 40 is formed. The resonance effect absorbs the mid- and high-frequency noise, so the noise prevention effect in the wide frequency range is excellent.
도 4는 마감재가 씌워진 도 1의 변형예를 보여주는 사시도이다.Figure 4 is a perspective view showing a variant of Figure 1 covered with a finish.
본 구체예에 있어서는 도 4에 도시된 바와 같이 발포 알루미늄 패널(10)의 외부에 노출되는 면에, 예를 들면, 페인트, 펄라이트(perlite), 규사, 펠트(felt) 등의 도장(46)을 하거나 직물, 부직포, 금속판, 엠보싱 금속판, 종이 시트 등의 마감재(48)를 접착하므로써, 마감재로서 요구되는 적절한 미감, 질감 및 촉감을 부여할 수 있다.In this embodiment, as shown in FIG. 4, for example, paint 46 such as paint, perlite, silica sand, felt, etc. is applied to the surface exposed to the outside of the foamed aluminum panel 10. By bonding the finishing materials 48 such as woven fabrics, nonwoven fabrics, metal plates, embossed metal plates, and paper sheets, appropriate aesthetics, texture, and feel required as the finishing materials can be imparted.
즉, 발포 알루미늄 패널(10)의 외측면에 페인트, 펄라이트, 규사 또는 펠트가 도장(46)을 하거나 직물, 부직포, 금속판, 엠보싱 금속판 또는 종이 시트의 마감재(48)를 접합시켜 외장을 이루게 할 수 있다.That is, the outer surface of the foamed aluminum panel 10 may be painted, pearlite, silica sand or felt painted 46 or bonded to the finishing material 48 of the woven fabric, nonwoven fabric, metal plate, embossed metal plate or paper sheet to form an exterior. have.
