본 발명은 공동주택, 차량 엔진룸, 철도차량, 벽체 및 바닥, 발전기 내부, 건설장비 내부, 체육관 바닥 및 벽체, 철도레일기초 등에서 발생되는 소음 및 진동 단열을 완벽하게 흡수 차단할 수 있으며, 흡음 진동 단열 성능에 따라 제품을 더 적층하거나 얇게 적층시킬 수 있을 뿐만 아니라 건축내장재로 사용할 경우에는 외부에 노출되는 면에 마감재를 덧붙여 사용할 수 있도록 설계 제조된 흡차음재 및 그 제조방법에 관한 것이다. The present invention can completely absorb and block the noise and vibration insulation generated in the apartment house, vehicle engine room, railway vehicles, walls and floors, generators, construction equipment, gym floors and walls, railway rail foundations, sound absorption vibration insulation The present invention relates to a sound absorbing and insulating material designed and manufactured to be able to further laminate or thin a product according to its performance, and to add a finishing material to a surface exposed to the exterior when used as a building interior material.
종래의 흡차음재 구성은 발포체, 유리섬유, 섬유휄트, 우레탄폼에 마감재를 덧붙여 사용하거나 레자에 구멍을 뚫어 발포체에 적층시켜 사용하였다. 심한 소음과 함께 진동이 발생할 경우 별도로 차음재나 재진재를 별도로 부착하여 여러장을 겹쳐서 사용하거나 설계 구조적으로 보완해야하기 때문에 시공이 불편하며 시공에 따른 인건비 상승으로 인하여 많은 문제점을 초래하였다. 예를 들자면 공동주택의 층간 소음방지를 위해서 설계변경하여 콘크리트 두께를 두껍게 변경하게 되면 건축물 기초를 더 튼튼히 하기위해 추가적인 비용이 소요되게 된다. 그리고 바닥에 추가적으로 덧붙여 시공하게되는 흡차음재일 경우 단순히 폴리스티렌 포옴이나, 재생타이어, 이브이에이 발포체등을 사용하여 뜬바닥 구조로 건축하였으나, 그 성능이 크게 개선되지 않았다. 또한, 흡차음 단열 재료는 폴리스티렌폼, 폴리우레탄폼, 유리섬유등의 단열재가 주종을 이루었다. 이러한 구조에서는 발생되는 흡음이나 차음 단열을 완벽하게 흡수 차단하기에는 어려움이 많았던 것이다. Conventional sound absorbing and insulating material was used by adding a finishing material to the foam, glass fiber, fiber felt, urethane foam, or by laminating the foam by punching the leather. In case of vibration with severe noise, it is necessary to attach several sound insulation materials or Jaejin materials separately, so that several sheets are overlapped or supplemented by design structure. For example, if the thickness of the concrete is changed by changing the design to prevent the noise between floors of the MDU, additional costs are required to strengthen the foundation of the building. In the case of the sound absorbing and insulating material to be added in addition to the floor, it was simply constructed using a polystyrene foam, recycled tires, Yves foam, etc., but the performance was not greatly improved. In addition, the sound absorbing and insulating heat insulating material mainly made of a heat insulating material such as polystyrene foam, polyurethane foam, glass fiber. In such a structure, it was difficult to completely absorb and block the sound absorbing or sound insulation generated.
이러한 문제점을 해결하고자 많은 연구가 있어 왔다.There have been many studies to solve this problem.

상기 제진시트는 상온에서 통상적으로 고형상태인 블로운아스팔트를 사용함으로써, 열 유동성을 억제하여, 스트레이트 아스팔트를 사용할 때에 비하여 상온이상의 영역에서 방진성이 저하는 문제점 및 오염성이 감소되었고, 20중량부 미만이면 밀착성이 저하되고, 40중량부를 초과하는 경우에는 낙입성 시험시 크랙이 발생하여 20~40중량부가 바람직하다.When the vibration damping sheet uses blown asphalt, which is generally solid at room temperature, the thermal fluidity is suppressed, so that the problem of dustproofness and pollution is reduced in an area above room temperature compared to when using straight asphalt, and contamination is less than 20 parts by weight. When adhesiveness falls and exceeds 40 weight part, a crack generate | occur | produces in a fall test, and 20-40 weight part is preferable.
분말상 또는 편상의 무기충전제는, 탄산칼슘, 탈크, 크레이, 마이카 및 운모중에서 선택된 어느 하나의 화합물 또는 2이상의 화합물을 사용하며, 특히, 마이카는 내한-내열성이 우수하여 전체 온도 영역에서의 열 유동성현상을 억제하게 되어 방진 기능을 유지하는데 매우 효과적이며, 또한 내한 및 내충격성을 보완하는 기능을 갖게된다. 사용량이 50중량부 미만이면 내오염성이 저하되고, 80중량부를 초과하는 경우에는 시팅성(Sheeting)이 저하되므로 50~80중량부가 바람직한 사용량 이다.Powdered or flaky inorganic fillers use any one compound selected from calcium carbonate, talc, cray, mica, and mica, or two or more compounds. In particular, mica has excellent cold resistance and heat resistance, which results in heat flow in the entire temperature range. It is very effective in maintaining the dustproof function, and also has a function to compensate for cold resistance and impact resistance. If the amount is less than 50 parts by weight, fouling resistance is lowered, and if it exceeds 80 parts by weight, sheeting (Sheeting) is lowered, so 50 to 80 parts by weight is the preferred amount.
점착제는 석유수지, 구마론수지, 폴리스티렌수지, 폴리에틸렌수지 및 에틸렌초산비닐수지 중에서 선택된 어느하나의 화합물을 사용하며 롤 성형성을 용이하게 하기 위하여 사용하며, 사용량이 1중량부 미만이면 성형시 롤 밀착성이 부족하며, 5중량부를 초과하면 상온에서 시트가 과도하게 경화(Hard)되는 문제가 발생하므로 1~5중량부가 바람직하다.The pressure sensitive adhesive uses any one compound selected from petroleum resin, kumaron resin, polystyrene resin, polyethylene resin and ethylene vinyl acetate resin, and is used to facilitate roll formability. This is insufficient, since the problem of excessively hardening the sheet (Hard) occurs at room temperature if it exceeds 5 parts by weight is preferably 1 to 5 parts by weight.
공정유는 석유계 혹은 식물성유를 사용하므로 특별히 한정할 필요가 없으며 각 성분들의 혼합 및 가공성을 향상시키기 위하여 사용한다.Process oil does not need to be particularly limited because it uses petroleum or vegetable oil, and is used to improve the mixing and processability of each component.
합성고무는 블로운 아스팔트 결합력 및 형상 유지력이 있으므로 형상의 변화를 적게하고, 열에 의한 재료의 결합력을 떨어뜨리는 문제를 방지하고, 넓은 온도범위에서 우수한 방진특성을 나타내기 위하여 사용되며, 스티렌-부타디엔스티렌터폴리머(Styrene-butadiene styrene terpolymer:SBS), 에틸렌프로필렌디엔고무 (Ethylene propylene diene rubber;EPDM), 및 스티렌-부타디엔고무(Styrene-butadiene rubber:SBR)중에서 선택된 어느 하나의 화합물을 사용한다.Synthetic rubber is used to reduce the change of shape, prevent the problem of dropping the bonding strength of materials due to the heat-blown asphalt binding force and shape retention force, and to show the excellent dustproof property over a wide temperature range, styrene-butadiene styrene Any one compound selected from styrene-butadiene styrene terpolymer (SBS), ethylene propylene diene rubber (EPDM), and styrene-butadiene rubber (SBR) is used.
유기섬유상 충전제는 제품의 강도를 보완함으로써 융착 전 시트상태의 현장 작업성을 부여하기 위하여 사용되며, 식물성 또는 합성섬유중에서 선택된 어느 하나의 유기 섬유를 사용하며, 사용량은 0.2~5중량부를 사용한다.The organic fibrous filler is used to give field workability of the sheet state before fusion by supplementing the strength of the product, using any one organic fiber selected from vegetable or synthetic fibers, and the amount used is 0.2 to 5 parts by weight.
이외에 추가적으로 생석회를 1~4중량부 사용하며 4중량부를 초과하는 경우에는 시팅작업성이 나빠지므로 4중량부 이하로 사용하는 것이 바람직하다.In addition to using 1 to 4 parts by weight of quicklime and more than 4 parts by weight it is preferable to use less than 4 parts by weight because the workability worsens.
상기 제진시트의 제조는 열에 의한 안정성 증가로 40℃이상의 영역에서도 제 진, 차음성능이 유지하며, 특히 난방열로 인한 제진, 흡음, 차음 성능저하를 방지할 수 있다.The manufacture of the vibration damping sheet is to maintain the vibration damping, sound insulation performance in the region of more than 40 ℃ due to increased stability by heat, in particular can prevent the vibration damping, sound absorption, sound insulation deterioration caused by heating.

실험예2 Experimental Example 2
실험개요 본 발명의 실시예와 종래의 제품과의 중간차음 투과손실성능비교 평가를 다음과 같이 하였다. Experimental Overview The evaluation of the comparison of the sound insulation loss performance between the examples of the present invention and the conventional products was as follows.
실험항목: 저주파(2~1600Hz)와 고주파(1600~6400Hz)대역의 관내 시험 Experimental item: In-house test of low frequency (2 ~ 1600Hz) and high frequency (1600 ~ 6400Hz) bands
측정기기: Acoustic Duct(9301)* 관내법에 의한 흡음율 측정장치 Measuring instrument: Acoustic Duct (9301)
투과손실의 정의 Definition of penetration loss
Ii = Ir + Ia + It Ii = Ir + Ia + It
τ = It / Ii, a = I - Ir / I τ = It / Ii, a = I-Ir / I
Ii : 입사음의 세기, Ir :반사음의 세기, Ia: 흡수음의 세기, Ii: intensity of incident sound, Ir: intensity of reflected sound, Ia: intensity of absorbed sound,
τ: 투과율, a : 흡음율 τ: transmittance, a: sound absorption
따라서, 투과손실이란 입사되어 재료로 들어오는 소음의 세기중 재료를 투과하지 못하고 재료 내에 흡수되어 소리에너지에서 다른 에너지의 형태로 변환되거나 재료 표면에서 반사된 소음의 세기를 의미하며, 흡음성이 좋은 재료란 입사음이 재료를 투과하지 못하고 대부분 흡수 또는 반사되어 투과손실의 값이 큰 재료를 의미한다. Therefore, the transmission loss means the intensity of noise that is absorbed in the material and is absorbed in the material and is reflected from the surface of the material or reflected from the surface of the material. The incident sound does not penetrate the material and is mostly absorbed or reflected, meaning a material having a large value of transmission loss.
질량의 법칙에서 In the law of mass
투과손실 (TL) = 18log(mf) -44(db) Transmission Loss (TL) = 18log (mf) -44 (db)
여기에서 m : 재료의 면밀도(kg/㎡). f: 주파수(Hz) Where m is the surface density of the material (kg / m 2). f: frequency (Hz)
재료의 차음 성능이 가장 중요한 영향인자의 하나로서 동일 재료에서 투과손실은 가청 주파수 대역에서 벽체 재료의 비중과 주파수에 비례한다. The sound insulation performance of the material is one of the most important influence factors. In the same material, the transmission loss is proportional to the specific gravity and the frequency of the wall material in the audible frequency band.
본 발명의 실시예에 의한 흡차음재에서 윗부분에 적용되는 아스팔트시트는 1.65~1.7의 고비중으로, 공기층을 다량 함유한 발포재료나 단순 섬유층으로만 이루어진 종래의 제품보다 월등한 차음성능을 나타냄을 알 수 있었다. Asphalt sheet applied to the upper portion of the sound absorbing and insulating material according to an embodiment of the present invention is a high specific gravity of 1.65 ~ 1.7, it can be seen that the sound insulation performance superior to the conventional products consisting only of a foam material or a simple fiber layer containing a large amount of air layer there was.
