Description

층간소음 방지 특성이 우수한 저방사 단열바닥재 제조방법{Low-emission flooring insulation manufacturing method prevents inter excellent noise characteristics}TECHNICAL FIELD [0001] The present invention relates to a low-emission flooring insulation manufacturing method,

본 발명은 층간소음 방지 특성이 우수한 저방사 단열바닥재 제조방법에 관한 것으로, 보다 상세하게는 충격음 차단, 공기전달음 차단, 열반사 저방사 단열 및 전도 단열을 포함한 4가지 기능을 동시에 만족하면서 크기를 시공조건에 맞게 최적화시킨 상태로 모듈화시킨 층간소음 방지 특성이 우수한 저방사 단열바닥재 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a low-radiation insulating floor material having excellent anti-noise characteristics, and more particularly, to a method of manufacturing a low- To a method of manufacturing a low-radiation insulating floor material having excellent interlayer noise-preventing characteristics modularized in a state optimized in accordance with construction conditions.

우리나라의 공동주택은 1980년도이래 대량 공급을 위한 주택정책에 따라 대부분 구조벽과 슬래브를 통해 건물의 하중을 지탱하는 벽식구조의 아파트를 지향하게 되었다.Since 1980, Korea 's apartment complex has been designed as a wall - mounted apartment that supports the load of the building through structural walls and slabs in accordance with the housing policy for mass supply.

이러한 벽식구조의 아파트는 라멘식구조의 아파트에 비해 시공비가 비교적 저렴하고 공사기간의 단축 등 경제성이 좋은 장점이 있어 물량중심의 주택공급 정책에 부응하여 왔다.These apartments with wall structure are more economical compared to the apartments with the Raman style structure, and the construction cost is relatively low and the construction period is short.

그런데, 벽식구조로 지어진 아파트는 세대간 소음 전달에 특히 취약한 문제가 있으며, 위와 같은 세대간 소음전파는 아파트 거주민의 가장 큰 불만사항으로서 그 가운데서도 아파트 직상층에서 발생되는 충격음이 직하층부로 전달되는 소음이 가장 크게 문제시되고 있다.However, apartment buildings constructed with wall structures are particularly vulnerable to generation-to-generation noise transmission, and such generation-to-generation noise propagation is one of the biggest complaints of apartment residents. Among them, Noise is the biggest problem.

특히, 최근에는 층간소음으로 인한 이웃 간의 분쟁이 심각한 사회문제로 대두되고 있다.Especially, recently, disputes among neighbors due to interlayer noise have become serious social problems.

통상, 아파트와 같은 공동주택에서는 상하층 간에 발생되는 충격음이 가장 큰 문제가 되는데, 이러한 충격음은 크게 경량 충격음과 중량 충격음으로 구분되며, 경량 충격음은 주로 물건이 떨어질 때 발생하는 소음을 말하고, 중량 충격음은 주로 사람이 뛸 때 발생하는 소음을 말한다.Generally, in an apartment house, the impact sound generated between the upper and lower floors is the biggest problem. The impact sound is divided into a light impact sound and a heavy impact sound. The light impact sound mainly refers to a noise generated when the object falls, Mainly refers to the noise that occurs when a person runs.

또한, 전달음을 기준으로 분류하자면, 아이들이 뛰는 행위 등으로 벽이나 바닥을 통해 전달되는 고체전달음과, 텔레비젼이나 오디오나 피아노 그리고 바이올린 같은 악기 등에서 발생해 공기를 타고 전달되는 공기전달음으로 나눌 수도 있다.In addition, according to the transmission sound, it is divided into a solid transmission sound transmitted through a wall or floor by children's play, and an air transmission sound generated by an instrument such as a television, an audio, a piano, and a violin It is possible.

그리고, 현재 아파트 층간소음에 대한 법적 기준에 따르면, 고체전달음의 경우 1분을 평균으로 계산하여 낮에는 43dB 이상, 저녁에는 38dB 이상이면 층간소음에 해당하며, 공기전달음의 경우에는 5분을 평균으로 계산하여 낮에는 45dB 이상, 저녁에는 40dB 이상이면 층간소음에 해당한다.According to the legal standard for the noise of the current apartment floor, it is calculated as 1 minute for the solid transmission sound, which is equivalent to 43dB in daytime and above 38dB in evening, and 5 minutes in case of air transmission sound When calculated as an average, it is equivalent to the interlayer noise when the daytime is 45 dB or more and in the evening is 40 dB or more.

그런데, 이와 같은 소음은 심리적으로 영향을 주어 불쾌감과 짜증을 유발하고, 공격적인 태도를 가질 수 있으며, 휴식과 수면을 방해하고, 사고력 저하, 대화 방해, 피로감 증대, 교감신경계 자극, 혈압상승 등을 유발하며, 장기적으로는 위궤양, 소화불량, 심장질환까지도 발생시킬 우려가 있는 것으로 보고되고 있다.However, such noises may cause psychological discomfort and irritation, aggressive attitudes, disruption of rest and sleep, decrease in thinking ability, interruption of communication, increased fatigue, stimulation of the sympathetic nervous system, In the long term, it is reported that gastric ulcer, dyspepsia and heart disease may occur.

그럼에도 불구하고, 대부분의 바닥재는 재상폐타이어 흡음재와 경량기포콘크리트를 혼용하는 경우, 혹은 단순 스티로폼, 아이소핑크 등의 층간소음재를 시공하는 경우에 그치고 있어 실제적인 층간소음 억제가 어려울 뿐만 아니라 비효율적이고 비용만 낭비하고 있는 형태일 뿐이다.Nevertheless, most of the flooring is only when the recycled tire sound absorbing material is mixed with the lightweight foamed concrete, or when the interlayer noise material such as simple styrofoam or isoprene is applied, so that it is difficult to effectively suppress the interlayer noise, It's just a form of wasting money.

최근에는 다양한 방식의 층간 소음재들이 개시되어 시공되고 있지만, 이들은 공기전달음 보다는 고체전달음을 완화시키는 기능에 치중된 경향이 있어 공기전달음 차단은 상대적으로 떨어지고, 또한 단열성능 확보는 또다른 문제로서 별개의 단열재를 다시 사용하여 시공해야 하는 불편함도 존재하고 있다.In recent years, various types of interlayer noise materials have been disclosed and constructed, but they tend to be more focused on the function of relieving the solid transmission sound than the air transmission sound, so that the air transmission sound blocking is relatively lowered. There is an inconvenience that it is necessary to use a separate insulation material again.

도 1 내지 도 3에 도시된 바와 같이, 본 발명에 따른 층간소음 방지 특성이 우수한 저방사 단열바닥재는 흡음패드(100)와, 상기 흡음패드(100)의 상면에 밀착되는 제1알루미늄필름(200)과, 상기 제1알루미늄필름(200) 상면에 합지되는 단열차음재(300)와, 상기 단열차음재(300)의 상면에 부착되는 제2알루미늄필름(400)과, 상기 제2알루미늄필름(400)의 상면에 합지되는 충격흡수패드(500)로 층상 구조가 이루어지도록 순차 적층되게 제조된다.As shown in FIGS. 1 to 3, the low-radiation thermal insulating floor material having excellent interlayer noise prevention characteristics according to the present invention comprises a sound absorbing pad 100, a first aluminum film 200 A second aluminum film 400 attached to the upper surface of the heat insulating sound insulating material 300 and a second aluminum film 400 attached to the upper surface of the second aluminum film 400. The heat insulating sound insulating material 300 is bonded to the upper surface of the first aluminum film 200, So that the layered structure is formed by the impact-absorbing pad 500 laminated on the upper surface of the substrate.

본 발명은 이와 같은 층상 구조를 갖도록 단열바닥재를 제조함으로써 충격음 차단, 공기전달음 차단, 열반사 저방사 단열, 전도 단열 등 4가지 특성을 동시에 모두 만족시킬 수 있고, 이를 통해 단열재시공과 층간소음재 시공을 분리하지 않고 한 번의 시공으로 모두를 충족시킬 수 있도록 구성된 것이다.The present invention can simultaneously satisfy all four characteristics such as impact sound blocking, air transmission shutoff, heat radiation low radiation insulation, and conduction insulation by manufacturing the insulating floor material having such a layered structure, It is structured so that it can meet all by one construction without separating construction.

즉, 본 발명 저방사 단열바닥재의 기저를 이루는 흡음패드(100)는 흡음특성을 강화시키기 위해 다공성 재질인 PU폼이 바람직하며, 표면은 예시와 같이 다수의 요철이 형성된 계란판 구조를 갖는다.That is, in order to enhance sound absorption characteristics, the sound absorbing pad 100 constituting the base of the low radiation thermal insulating flooring of the present invention is preferably a porous PU foam, and the surface thereof has an egg plate structure having many concavities and convexities as shown in the figure.

그러면, 공기전달음과 같은 소음은 선행기술처럼 헬름홀츠 공명효과는 아니더라도 다공에 의한 반사, 굴절, 분산되면서 흡음이 일어나고, 특히 요철 부분인 계란판 구조의 판면에서 극심한 난반사가 일어나면서 에너지 소멸이 일어나 공기를 통한 소음전달 감쇠 특성히 현격히 증대되어 소음 차단 목적을 달성할 수 있게 된다.Then, the noise such as air transmission sound is reflected by the pores, the sound is absorbed while being diffused, refracted, and dispersed even though it is not Helmholtz resonance effect as in the prior art. Especially, the extreme diffuse reflection occurs on the plate surface of the egg plate structure, So that the noise cancellation object can be achieved.

특히, 상기 흡음패드(100)의 요철 중 철(凸)부에 해당하는 꼭지점 부분이 후술되는 단열차음재(300)의 공기층(310)에 끼워지도록 배치된 상태에서 접착방식으로 합지되어야 한다. 그래야, 충격흡수는 물론 흡음특성을 극대화시킬 수 있다.Particularly, a vertex portion corresponding to a convex portion of the concave and convex portions of the sound absorbing pad 100 should be laminated in an adhesive manner in a state in which it is arranged to be fitted in the air layer 310 of the heat insulating sound insulating material 300 described later. That way, it can maximize shock absorption as well as sound absorption characteristics.

그리고, 상기 제1,2알루미늄필름(200,400)은 복사열손실을 방지하여 복사단열 특성을 높이기 위한 것이다.The first and second aluminum films 200 and 400 are used to prevent radiant heat loss, thereby enhancing radiant heat insulation characteristics.

이 경우, 상기 제1알루미늄필름(200)은 요철, 즉 계란판 구조를 갖는 형상부에 부착되어야 하기 때문에 접착제를 도포한 상태에서 흡음패드(100)의 요철 반대쪽에서 강한 흡입압으로 빨아 들여 제1알루미늄필름(200)이 강제 흡착되는 방식으로 접착, 합지되게 구성함이 바람직하다.In this case, since the first aluminum film 200 should be attached to the irregularities, that is, the shape having the egg plate structure, the first aluminum film 200 is sucked into the strong suction pressure on the opposite side of the irregularities of the sound absorbing pad 100, It is preferable that the aluminum film 200 is adhered and laminated in such a manner that the aluminum film 200 is strongly adsorbed.

이것이 가능한 이유는 흡음패드(100)가 두께방향으로 관통된 다수의 공극을 갖는 재료를 사용하기 때문이다.This is possible because the absorbing pad 100 uses a material having a plurality of voids penetrated in the thickness direction.

그러면, 도 2에서 예시하는 바와 같이, 상기 제1알루미늄필름(200)은 상기 흡음패드(100)의 요철형 표면에 동일 형상을 유지하면서 완전히 접착되어 합지되면서 표면을 코팅한 것처럼 한 겹의 필름막을 구성하게 되어 복사단열 특성을 향상시키게 된다.2, the first aluminum film 200 is formed by laminating a single layer of a film film such that the first aluminum film 200 is completely adhered to the concave-convex surface of the sound absorbing pad 100, And the radiation insulation property is improved.

아울러, 상기 제2알루미늄필름(400)은 단열차음재(300)의 상면에 접착되어 합지되게 되는데, 이렇게 하여 제1,2알루미늄필름(400) 사이에 단열차음재(300)가 위치되게 함으로써 복사열손실을 방지하게 되는 것이다. 즉, 제1,2알루미늄필름(400)은 2단에 걸쳐 적외선 상태로 이동하는 복사열을 고반사 원리로 반사 차단함으로써 복사열로 인한 손실을 현격히 줄여 주어 보열특성을 강화시키는 복사단열을 가능케 하는 기능을 담당하게 된다.The second aluminum film 400 is bonded to the upper surface of the heat insulating sound insulating material 300 so that the heat insulating sound insulating material 300 is positioned between the first and second aluminum films 400, . That is, the first and second aluminum films 400 have a function of allowing radiant heat moving in two-stage infrared rays to be reflected and shielded by a high reflection principle, thereby remarkably reducing loss due to radiant heat, I will be in charge.

한편, 상기 단열차음재(300)는 전도단열 기능을 담당하는 수단으로서, 공기층에 의한 단열효과를 극대화시키기 위한 것이며, 이는 단열 외에도 고체전달음, 즉 직접 충격음의 파쇄, 감쇠, 흡음 기능도 담당하게 된다.Meanwhile, the heat insulating sound insulating material 300 is a means for carrying out the conduction heat insulating function, and is for maximizing the heat insulating effect by the air layer. In addition to the heat insulating, the sound insulating sound insulating material 300 is also responsible for crushing, .

이를 위해, 상기 단열차음재(300)는 타공된 발포폴리에틸렌수지로 형성되며, 내부에는 다이아몬드 혹은 마름모, 더 바람직하게는 벌집모양의 공기층(310)을 갖도록 구성된다.To this end, the heat insulating sound insulating material 300 is formed of perforated foamed polyethylene resin, and is configured to have diamond or rhombus, more preferably honeycomb air layer 310 therein.

때문에, 구조적으로 강도를 유지하면서 단열을 물론, 흡음 기능도 갖출 수 있게 된다.Therefore, it is possible to provide not only insulation but also sound absorbing function while maintaining the structural strength.

마지막으로, 상기 충격흡수패드(500)는 탄성계수를 줄이는 기능을 담당함으로서 충격음을 흡수하도록 실리콘 혹은 고무로 형성됨이 바람직하나, 수명과 내오염성 유지를 위해 실리콘 60-70중량%에 0.5㎛의 입도를 갖는 규회석 미분 10-15중량% 및 나머지로 CMC(CarboxyMethyl Cellulose)를 혼용하여 제조함이 바람직하다.Lastly, the impact absorbing pad 500 preferably has a function of reducing the elastic modulus, and is preferably formed of silicone or rubber so as to absorb the impact sound. However, in order to maintain the life and stain resistance, 60-70% 10-15% by weight of a wollastonite fine powder having a weight average molecular weight of 100,000 and carboxymethyl cellulose (CMC) as a balance.

이때, 규회석 미분은 바늘형태의 침상구조를 하고 있는 규회석을 분말화 한 것을 사용하는데, 저흡습성이고 결정수가 없으므로 치수안정성이 뛰어나 성형 후 안정화는 물론 내오염성이 향상되며, 상기 CMC는 폴리머 바인더로서 인장강도 및 굴곡강도를 증대시키기 위해 첨가된다.In this case, the wollastonite fine powder is obtained by pulverizing wollastonite having a needle-like needle-like structure. Since the wollastonite powder is low in hygroscopicity and lacks crystals, it is excellent in dimensional stability and stabilizes after molding and also improves stain resistance. The CMC is a polymer binder Strength and flexural strength.

이렇게 구성하게 되면, 본 발명은 기존에 단열과 층간소음 방지재가 별도로 분리 시공되던 불편함, 이중으로 지출되던 비용낭비를 막고, 한 번의 시공으로 단열은 물론 층간소음을 동시에 막을 수 있게 된다.According to the present invention, it is possible to prevent the inconvenience that the insulation and the interlayer noise preventing member are separately separated from each other, and the waste of expenses, which is incurred in the past, and to prevent the insulation noise as well as the interlayer noise at the same time.

특히, 단열의 경우에도 열반사 저방사 단열 특성과 전도 단열 특성 2가지를 동시에 만족시키므로 얇은 두께에도 불구하고 단열특성이 매우 우수하며, 나아가 소음 차단 특성에 있어서도 탄성흡수와 같은 기본적인 충격음 차단은 물론 공기층과 공극을 활용한 공기전달은 차단 특성까지 우수하므로 앞서 설명한 4가지 특성을 동시에 만족하는 독특 현저한 특성을 가진 바닥단열재를 제공할 수 있게 된다.Particularly, even in the case of adiabatic heat insulation, both of the heat radiation low radiation heat insulation characteristic and the conduction insulation property are satisfied at the same time. Therefore, the adiabatic characteristic is excellent despite the thin thickness, and furthermore, It is possible to provide a bottom insulating material having unique characteristics that simultaneously satisfy the above-mentioned four characteristics.

나아가, 도 4에서와 같이 충격흡수패드(500)를 일측으로 돌출되게 모듈화시키게 되면 평균 시공면적에 최적화된 상태로 시공 편의성도 증대시키면서 모듈간 겹침에 따른 소음 전파 차단 기능도 강화시킬 수 있게 된다.4, when the impact absorbing pad 500 is modularly protruded to one side, it is possible to enhance the ease of installation in a state optimized for the average construction area, and also to enhance the noise shielding function according to overlapping between modules.

즉, 충격흡수패드(500)의 인접한 적어도 2변이 단열차음재(300)보다 돌출되게 배열되어 시공시 겹칠 수 있도록 구성되어야 하는 것이다.That is, at least two adjacent sides of the impact absorbing pad 500 are arranged so as to protrude from the heat insulating sound insulating material 300 so that they can overlap at the time of construction.

뿐만 아니라, 접착특성을 증대시키기 위해 본 발명에서는 아크릴수지 100중량부에 대해 EOR(에틸렌 옥텐 러버) 10-20중량부, 전분풀 5-10중량부, 소디움벤조에이트(Sodium Benzoate) 3-6중량부 및 적토(Red Mud) 1-3중량부로 조성된 접착제를 사용할 수 있다.In addition, 10-20 parts by weight of EOR (ethylene octene rubber), 5-10 parts by weight of a starch paste, 3-6 parts by weight of sodium benzoate (weight per 100 parts by weight of acrylic resin) And 1 to 3 parts by weight of Red Mud may be used.

이때, 아크릴수지는 대표적인 접착수지이며, EOR은 에틸렌 옥텐 러버로서 투명성을 유지하면서 가교에 따른 접착능력 향상을 위해 첨가되고, 상기 전분풀은 천연증점제로서 접착기능을 강화하기 위해 첨가되며, 상기 소디움벤조에이트는 곰팡이 방지 및 방부성을 위해 첨가되고, 적토는 수산화알루미늄 제조공정에서 발생하는 광물성 폐기물로서 충진제로 사용되어 접착특성을 안정화시키게 된다.At this time, the acrylic resin is a typical adhesive resin, and EOR is added as an ethylene octene rubber to improve the adhesive ability according to crosslinking while maintaining transparency, and the starch paste is added as a natural thickener for enhancing the adhesive function, Eight is added for mold prevention and antifouling, and the red soil is a mineral waste generated in the aluminum hydroxide manufacturing process, which is used as a filler to stabilize the adhesive properties.
