Description
본 발명은 다중벽탄소나노튜브를 함유하는 건축물의 층간소음 저감용 단열재에 관한 것으로, 보다 상세하게는 시멘트 등에서 발생하는 독성을 차단함과 동시에 아파트, 빌라, 다가구 주택, 오피스텔 등과 같은 공동주택의 상하층 혹은 수평층 사이에서 발생하는 소음과 진동을 차단하고 건물 벽의 단열 성능을 개선시키고 시공의 편리함을 도모하는 다중벽 탄소나노튜브를 함유하는 건축물의 층간소음 저감용 단열재에 관한 것이다.The present invention relates to an insulation for reducing noise between floors of a building containing multi-walled carbon nanotubes, and more specifically, to prevent toxicity generated from cement and the like, and to top and bottom of apartment houses such as apartments, villas, multi-family houses, officetels, and the like. The present invention relates to an insulation material for interlayer noise reduction of a building containing multi-walled carbon nanotubes that blocks noise and vibration generated between floors or horizontal floors, improves the insulation performance of a building wall, and facilitates construction.
본 발명은 동일한 발명자에 의한 특허출원 제10-2010-37244호(2010.10.28일자 특허결정서 발행)의 도료조성물을 그대로 이용한 이용발명에 관한 것이다. The present invention relates to a use invention using the paint composition of Patent Application No. 10-2010-37244 (issued by a patent decision dated October 28, 2010) by the same inventor.
일반적으로 건축물 등의 벽은 콘크리트로 시공되어 층간소음에 취약한 문제가 있다. 아파트, 빌라, 다가구 주택, 오피스텔 등과 같은 공동주택의 경우 윗집 혹은 옆집에서 발생한 고체 전달음은 건축물의 바닥은 물론 벽체를 타고 옆집 혹은 아래층으로 그대로 전달되어진다. 예를 들어, 물건의 낙하 등의 충격이 바닥에 가해지거나 의자를 옮기는 소리 등은 고체 전달음을 발생시키고 이 고체 전달음은 바닥슬래브와 벽체를 통해 인접한 다른 방 및 아래층에 전달된다. In general, walls such as buildings are constructed of concrete, there is a problem vulnerable to noise between floors. In the case of multi-unit houses such as apartments, villas, multi-family houses and officetels, the solid sound from the upper or next door is transmitted to the next floor or the lower floor as well as the floor. For example, an impact such as a drop of an object is applied to the floor or a movement of a chair generates a solid transmission sound, which is transmitted through the floor slab and the wall to another adjacent room and the lower floor.
이러한 공동주택의 바닥구조 내지 벽체가 층간소음을 효과적으로 흡수, 차단시켜주지 못하는 문제점으로 인하여 상하층 내지 수평층에 살고 있는 거주민들 간의 분쟁이 발생하는 등 층간소음으로 인한 문제가 점점 심각해지고 있어 최근에는 공동주택 상하층 간의 층간소음을 줄여주는 저감재의 사용이 의무화되기에 이르렀다.Due to the problem that the floor structure or the wall of the multi-family house cannot effectively absorb and block the noise between floors, the problems caused by the noise between floors have become more serious recently. It has become mandatory to use abatement materials that reduce the noise between floors of upper and lower apartments.
이에 대하여 벽체로부터 전달되는 층간소음을 줄이기 위해 종래 각종 방음재 등을 벽면에 설치하여 소음을 감쇄시키고자 하는 시도가 있어 왔지만, 그 소재가 고가이고 유효적절하게 충격음을 차폐하지는 못하는 문제점을 가지고 있다.On the other hand, attempts have been made to attenuate the noise by installing various soundproofing materials on the wall in order to reduce the inter-layer noise transmitted from the wall, but the material has a problem that it is expensive and does not effectively shield the impact sound.
또한 기존의 단열재들은 단열기능에만 초점이 맞추어져 층간소음의 차폐를 위한 기능이 포함되어 있지 않을 뿐만 아니라 시멘트로부터 유출되어지는 독성의 차단기능도 거의 기대할 수 없는 상황이다.
In addition, the existing insulation materials are focused only on the insulation function, which does not include the function for shielding the noise between floors, and there is little expectation of the toxic blocking function from the cement.
본 발명은 상기한 바와 같은 종래기술이 갖는 한계를 극복하기 위해 시공이 간단한 단열재에 단열기능과 함께 층간소음방지능을 제공하고자 하는 것으로, 그 주된 목적은 시멘트 등에서 발생하는 독성을 차단함과 동시에 아파트, 빌라, 다가구 주택, 오피스텔 등과 같은 공동주택의 상하층 내지 수평층 사이에서 발생하는 소음과 진동을 차단하고 건물 벽체의 단열 성능을 개선시키고 시공의 편리함을 도모하는 다중벽 탄소나노튜브를 함유하는 건축물의 층간소음 저감용 단열재를 제공함에 있다.The present invention is to provide a layer insulation noise prevention function with a thermal insulation function to a simple insulating material in order to overcome the limitations of the prior art as described above, the main object is to block the toxicity generated in cement, etc. Building containing multi-walled carbon nanotubes that blocks noise and vibration generated between the upper and lower floors and horizontal floors of multi-unit houses such as villas, villas, multi-family houses, officetels, etc., improves the insulation of building walls and facilitates construction. To provide a heat insulating material for reducing the interlayer noise of the.
