Description

건축물의 층간 단열차음재{Interlayer insulation sound insulation materials of buldings}Interlayer insulation sound insulation materials of buldings

본 발명은 건축물의 층간 바닥 충격음인 중량충격음과 경량충격음의 전달을 모두 감소시킬 수 있는 단열차음재에 관한 것으로서, 보다 상세하게 설명하면, 건축물의 슬라브의 상부에 폴리스티렌을 주재로 하되, 열가소성 엘라스토머를 포함하여 압축발포 성형되는 충격감소부재를 설치하여 아이들이 가지고 노는 장난감 등 물건을 떨어뜨리는 소리 즉, 경량충격음과 아이들이 뛰어다님에 따라 발생되는 중량충격음을 모두 감소시킴은 물론 상기 열가소성 엘라스토머에 의해 압축발포 성형되는 폴리스티렌이 쉽게 파손되는 것을 방지할 수 있는 건축물의 층간 단열차음재에 관한 기술분야이다.The present invention relates to an insulating sound insulation material capable of reducing the transmission of both heavy impact sound and light impact sound, which are floor impact sounds between floors of a building. By installing a compression foaming shock reducing member, the sound of dropping objects such as toys that children play with, that is, both the light impact sound and the heavy impact sound generated by children running around, is reduced as well as compression foamed by the thermoplastic elastomer. It is a technical field related to the sound insulation material between the floors of a building that can prevent the molded polystyrene from being easily damaged.

최근 공동주택 등에서 층간소음 문제로 인해 이웃 간의 살인과 방화, 폭행 등의 사건이 자주 발생하면서 공동주택의 층간소음은 심각한 사회적 문제로 떠오르고 있다.Recently, due to the noise problem between floors in apartment houses, murder, arson, and assault between neighbors have occurred frequently.

한편, 국내 대부분의 공동주택에 사용되고 있는 콘크리트는 무겁고 밀실하기 때문에 동일한 두께의 다른 재료보다 사람의 말소리나 TV 소리 등 공기를 매체로 하여 전달되는 소음에 대해서는 차단성능이 우수하다.On the other hand, because the concrete used in most apartment houses in Korea is heavy and closed, it has better blocking performance against noise transmitted through air, such as human speech or TV sound, than other materials of the same thickness.

그러나 상기 콘크리트는 재료의 특성상 표면에 직접 충격이 가해짐에 따라 발생하는 충격음이 콘크리트 슬라브 또는 벽체를 통해 인접 세대에 쉽게 전달되는 경향이 있다.However, due to the characteristics of the material of the concrete, the impact sound generated when a direct impact is applied to the surface tends to be easily transmitted to adjacent households through the concrete slab or wall.

이러한 충격음은 현재 사용되고 있는 바닥구조로는 해결하기가 쉽지 않은 실정이고, 이러한 문제를 해결하기 위해 독일이나 프랑스 등에서는 오래 전부터 뜬바닥 구조를 채용하고 있다.It is not easy to solve such an impact sound with the currently used floor structure, and in order to solve this problem, Germany and France have long adopted the floating floor structure.

최근 국내에서도 상기와 같은 문제를 해결하기 위한 노력이 학계는 물론 대형건설사와 건축 자재 업체 등을 중심으로 활발히 이루어지고 있고, 이러한 노력의 대부분은 단열차음재의 개발로 이어지고 있다.Recently in Korea, efforts to solve the above problems have been actively made centered on large construction companies and building material companies as well as academia, and most of these efforts are leading to the development of insulation and sound insulation materials.

상기와 같은 충격음 중 바닥충격음을 저감하기 위한 방법 중 가장 효과적인 것으로 알려진 뜬바닥 공법의 효과는 바닥슬라브, 벽 등의 구조체와 온돌 층을 절연해주는 단열차음재의 역할이 매우 중요하다.Among the above impact sounds, the floating floor method, which is known to be the most effective method for reducing floor impact sounds, plays a very important role of insulating sound insulation materials that insulate the floor slabs and structures such as walls and the ondol layer.

이러한 중요성 때문에 오래전부터 뜬바닥 공법을 적용해 오고 있는 독일 등 유럽 각국이나 일본 등에서는 뜬바닥용 단열차음재의 종류, 크기, 품질, 시험방법, 시공방법 등을 규정하여 시행하고 있으나 아직까지 국내에는 이러한 판단규정이 없어 단열차음재 선정에 어려움을 겪고 있는 실정이다.Because of this importance, European countries such as Germany, where the floating floor method has been applied for a long time, and Japan, etc., have prescribed and implemented the type, size, quality, test method, and construction method of insulation and sound insulation materials for floating floors. There are no judgment rules, so it is difficult to select insulation and sound insulation materials.

특히, 우리나라의 공동주택은 대부분 슬라브층, 슬라브 상부의 단열층, 경량 콘크리트 또는 기포 콘크리트층, 난방 코일층 및 마감 몰타르층 등을 포함하는 온돌 바닥 구조로 이루어져 슬라브 상부의 단열층을 발포성 스티로폼으로 시공하기 때문에 바닥 충격음에 대한 저감효과는 미비한 실정이다.In particular, most apartment houses in Korea consist of an ondol floor structure including a slab layer, an insulating layer on the top of the slab, a lightweight concrete or foam concrete layer, a heating coil layer, and a finishing mortar layer. The effect of reducing the floor impact sound is insignificant.

이와 같은 층간소음 문제를 해결하기 위한 건축물의 층간 콘크리트에 폐타이어 분쇄물, 아크릴, 우레탄 등을 혼합하여 타설하는 방식은 소음차단 효과가 떨어져 폴리에틸렌, 폴리프로필렌, 폴리스타일렌 등의 발포 폼을 층간소음재로 시공하고 있다.The method of mixing and pouring waste tire pulverized material, acrylic, urethane, etc. into the inter-floor concrete of a building to solve the inter-floor noise problem is not effective in blocking noise, so foams such as polyethylene, polypropylene, and polystyrene are used as inter-floor noise materials. is being constructed with

상기 폐타이어 분쇄물은 바닥 충격음 성능이 우수하나 시공의 어려움으로 인하여 사용되지 않고 있는 실정이고, 상기 폐타이어 분쇄물과 유사한 부틸 고무는 바닥 충격음 성능이 우수하나 가격이 높아 사용되지 않고 있는 실정이다.The pulverized waste tire has excellent floor impact sound performance, but is not used due to difficulty in construction, and butyl rubber similar to the pulverized waste tire has excellent floor impact sound performance but is not used due to its high price.

한편, 공동주택의 층간소음은 아파트, 연립주택, 다세대주택에서 발생하는 송음공해로 아이들이 뛰는 소리, 발자국 소리, 화장실 물소리, 가구 끄는 소리, 피아노 소리, 오디오 소리, TV 소리 등을 총칭한다.On the other hand, inter-floor noise in apartment houses is a collective term for sounds of children running, footsteps, toilet water, turning off furniture, piano sounds, audio sounds, TV sounds, etc.

이러한 층간소음은 물건의 낙하, 어린이의 놀이 등으로 발생한 충격이 바닥을 진동시켜 각층에 소음을 일으키는 것으로 경량충격음과 중량충격음으로 구분된다.Such inter-floor noise is divided into light impact sound and heavy impact sound, as impacts caused by falling objects or children's play vibrate the floor and cause noise in each floor.

상기 경량충격음은 아이들이 가지고 노는 장난감 등 물건 떨어지는 소리가 대표적이고, 작은 물건의 낙하, 가구를 끄는 소리 등 가볍고 딱딱한 소리로 충격력이 작고 지속시간이 짧은 특징이 있다.The light impact sound is representative of the sound of falling objects, such as toys that children play with, and is characterized by a small impact force and a short duration as a light and hard sound, such as a sound of a small object falling or furniture being pulled.

상기 중량충격음은 아이들이 쿵쿵 뛰는 소리가 대표적이고, 어린이가 뛰거나 달릴 때의 무거운 바닥충격음으로 충격음이 크고 지속시간이 큰 특징이 있다.The weight impact sound is representative of the sound of children jumping, and it is a heavy floor impact sound when children run or run, and the impact sound is large and has a long duration.

상기와 연관하여, 한국환경공단 층간소음 이웃 아이 센터에서 분석한 소음발생원 분석 자료에 따르면 아이들의 발걸음이나 뛰는 소리가 층간소음 발생원인의 대부분인 74.2%로 나타났다.In relation to the above, according to the noise source analysis data analyzed by the child center for noise between floors by the Korea Environment Corporation, the sound of children's footsteps or running was found to account for 74.2% of the causes of noise between floors.

주택건설기준 등에 관한 규정에 따르면 건축물의 바닥구조는 슬라브 두께 210㎜ 이상이면서 바닥충격음 중 경량충격음 58db 이하, 중량충격음 50db 이하로 규정되어 있고, 현재 시공되고 있는 공동주택의 경우 경량충격음 58db 이하는 어느 정도 해결하고 있으나 중량충격음 50db 이하는 해결하지 못하고 있는 실정이다.According to the regulations on housing construction standards, the floor structure of a building has a slab thickness of 210 mm or more and a light impact sound of 58 db or less and a heavy impact sound of 50 db or less among floor impact sounds. However, it is not possible to solve the weight impact sound of 50db or less.

이와 관련하여, 2013년 11월에 한국소비자원의 "공동주택 층간소음 저감제품 안전실태조사 결과보고"를 참조하면 시판되고 있는 모든 제품에서 중량충격음에 대해서는 효과가 없는 것으로 보고하고 있다.In this regard, referring to the "Report on the safety status of products for reducing noise between floors in apartments" of the Korea Consumer Agency in November 2013, it is reported that all products on the market have no effect on heavy impact sound.

종래기술의 일예로, 대한민국 공개특허 제10-2002-0020480호에는 기존 스티로폴에 폐타이어 분말을 부착시켜 방진과 단열을 충족시키는 단열 충격음 완충재인 폐타이어 분쇄물과 스티로폴을 이용한 바닥충격 완충재를 제시하고 있으나 폐타이어 분쇄물을 압착하여 스티로폴에 부착하는 방식으로 공정이 매우 복잡하고 비용이 많이 소요되는 단점이 있다.As an example of the prior art, Korean Patent Laid-Open Publication No. 10-2002-0020480 proposes a floor impact cushioning material using crushed waste tires and Styropoles, which are an adiabatic impact sound cushioning material that satisfies dust and heat insulation by attaching waste tire powder to existing Styropoles, However, there is a disadvantage in that the process is very complicated and costly in a way that the crushed waste tire is compressed and attached to the styropole.

또 다른 종래기술의 일예로, 대한민국 공개특허 제10-2018-0135664호에는 에틸렌비닐아세테이트와 무수말레인산이 그라프트된 폴리에틸렌을 기재로 하는 경량충격음 저감발포체용 조성물과 접착층 발포제용 조성물, 그리고 부분 수첨 스티렌 부타디엔 블록 공중합체와 무수말라인산이 그라프트된 폴리에틸렌을 기재로 하는 중량 충격음 저감 발포체용 조성물을 적층하고 이를 일체로 성형하여 경량충격음과 중량충격음을 저감시킬 수 있는 층간 소음 완충재의 제조방법을 제시하고 있으나,As another example of the prior art, Korean Patent Laid-Open No. 10-2018-0135664 discloses a composition for a lightweight impact sound reduction foam based on polyethylene grafted with ethylene vinyl acetate and maleic anhydride, a composition for an adhesive layer foaming agent, and partially hydrogenated styrene A method of manufacturing an interlayer noise cushioning material that can reduce light impact sound and weight impact sound by laminating a composition for weight impact sound reduction foam based on polyethylene grafted with butadiene block copolymer and malic anhydride as a base material and molding it integrally but,

경량충격음 저감을 위한 발포제와 중량충격음 저감을 위한 발포체를 따로 제조하여 적층하는 방법으로 매우 복잡하고 제품 제조를 위한 시설 비용이 많으며 경량충격음 저감을 위한 발포제와 중량충격음 저감을 위한 발포체를 따로 제조하여 적층하기 때문에 적층을 위한 추가 비용이 발생되는 문제가 있다.It is a method of separately manufacturing and laminating a foaming agent for light impact sound reduction and a foaming agent for weight impact sound reduction, which is very complicated and has a lot of facility cost for manufacturing the product. Therefore, there is a problem in that an additional cost for lamination is generated.

또 다른 종래기술의 일예로, 대한민국 등록특허 제10-0809450호에는 폐타이어를 분쇄하여 기계적으로 표면 개질한 입경 0.2~1.0mm의 폐타이어 미분말과 액상 천연고무를 혼합한 혼합액을 탄성 EPS 보드의 표면에 도포하여 제조되는 폐타이어 개질고무와 액상고무 혼합액을 이용한 탄성 EPS 층간 완충재 및 이의 제조 방법을 제시하고 있으나, 탄성 EPS 보드의 표면에 혼합액을 도포한 후 솔벤드를 건조하는 과정이 필요하며 이때 발생하는 솔벤트를 잡기 위한 시설이 필요하여 작업 공정이 복잡하고 시설비용이 많이 발생되는 단점이 있다.As another example of the prior art, in Korean Patent Registration No. 10-0809450, a mixture of fine powder of waste tires with a particle diameter of 0.2 to 1.0 mm and liquid natural rubber, which is mechanically surface-modified by pulverizing waste tires, is mixed with the surface of the elastic EPS board. An elastic EPS interlayer cushioning material using a mixture of waste tire modified rubber and liquid rubber manufactured by applying it to a rubber sheet and a manufacturing method thereof are presented, but a process of drying the solvent is required after applying the mixture to the surface of the elastic EPS board There is a disadvantage in that the work process is complicated and the facility cost is high because a facility to catch the solvent is required.
