Description
본 발명은 소음을 차폐하기 위한 차음재에 관한 것으로, 특히 건축구조물의 바닥내에서 소음을 차폐할 수 있으면서 그 위에 설치되는 배관과 바닥재 등의 하중을 견딜 수 있도록 된 차음재에 관한 것이다. The present invention relates to sound insulation materials for shielding noise, and more particularly, to sound insulation materials capable of withstanding loads such as pipes and flooring materials installed thereon while shielding noises within the floor of a building structure.
일반적으로, 상업용 또는 주거용 건축물, 특히 아파트와 같은 공동주택에서 바닥을 형성할 때에는 슬래브상에 단열을 위한 경량콘크리트층을 형성한 후에 그 위에 배관을 얹고 몰탈로 마감하였다.In general, when forming floors in commercial or residential buildings, especially apartments such as apartments, after forming a lightweight concrete layer for insulation on the slab, the pipes were laid on it and finished with mortar.
그러나, 전술한 방식으로 공동주택의 바닥을 형성하는 경우에는 소음(消音)을 위한 수단이 형성되어 있지 않아서, 아래층으로 소음(騷音)이 전달되어 아래층 주민들의 쾌적한 주거환경을 조성하는 데에 지장을 초래하였다. 더구나, 근래에는 대부분의 시공자가 환경문제를 고려하지 않은 채로 구조역학적인 문제만 해결된다고 하면, 오히려 건축비용의 절감을 위해 바닥의 두께를 더 얇게 시공하고 있는 실정이다.However, in the case of forming the floor of the multi-family house in the above-described manner, no means for noise are formed so that the noise is transmitted downstairs, which makes it difficult to create a pleasant living environment for the residents below. Resulted. In addition, in recent years, if most of the contractors solve only structural problems without considering the environmental problem, rather the construction of the floor is thinner to reduce the construction cost.
한편, 건축구조물의 이러한 소음문제를 해결하기 위한 차음재가 제안되었는 바, 예컨대 폐타이어에서 발생된 폐고무를 이용하거나 저밀도 발포수지를 이용하여 차음층이 형성되었다. 하지만, 이러한 차음재는 소음방지성능만 중점적으로 고려되었기 때문에, 건축구조물에 적용될 때 그 위에 설치되는 배관과 바닥재 등의 하중을 견디지 못한다고 하는 문제점이 있었다. On the other hand, a sound insulation material has been proposed to solve this noise problem of building structures, for example, the sound insulation layer was formed using waste rubber generated from waste tires or using low density foamed resin. However, since the sound insulation material was considered only as the noise prevention performance, there was a problem that it does not bear the load of pipes and flooring materials installed thereon when applied to a building structure.
이에 본 발명은 상기와 같은 문제점을 해결하고자 안출된 것으로, 본 발명은 밀도가 다른 층들을 적어도 2층으로 적층하여 구성함으로써, 차음(遮音)은 물론 요구되는 강도 및 단열효과를 갖는 차음재를 제공하는 데에 그 목적이 있다. Accordingly, the present invention has been made to solve the above problems, the present invention is configured by stacking at least two layers with different densities, to provide sound insulation as well as sound insulation (遮 音) with the required strength and insulation effect Its purpose is to.
상기와 같은 목적을 성취하기 위한 본 발명은, EVA(Ethylene vinylacetate)와 폴리에틸렌을 주원료로 하고서 다공질 충진제와, 가교제, 이형제 및, 발포제를 혼합한 기저층과, EVA를 주원료로 하고서 다공질 충진제와, 가교제, 이형제 및, 발포제를 혼합한 제 2층을 함께 가압발포함으로써 형성된다. 또, 상기 기저층의 밑면에는 다수의 돌출부가 형성되어 있는 것을 특징으로 한다. In order to achieve the above object, the present invention is a base material comprising a porous filler with EVA (ethylene vinylacetate) and polyethylene, a crosslinking agent, a mold release agent, and a blowing agent, a porous filler with a EVA, a crosslinking agent, It is formed by pressurizing and foaming together a mold release agent and the 2nd layer which mixed the blowing agent. In addition, the bottom surface of the base layer is characterized in that a plurality of protrusions are formed.
또한, 본 발명은 EVA를 주원료로 하고서 황토를 다공질 충진제로, 그리고 가교제와 이형제 및 발포체를 혼합한 제 3층을 추가로 구비할 수 있는 것을 특징으로 한다.

In addition, as shown in FIG. 1, on the second layer 2, EVA having a weight ratio of 65 to 85% is used as the main raw material, and ocher is used as the porous filler, for example, 0.5 to 0.5 such as DCP and PBP. The base layer 1 and the second layer 3 were added by adding a crosslinking agent of 1.0%, a release agent of 0.7% stearic acid, and a blowing agent which is an azo di carbonamide having a weight ratio of 3 to 10%. It can be formed by pressure-foaming the layer 2 and the third layer 3 together. At this time, the specific gravity of the base layer 1 is 99.6 GR / cm 3 , the specific gravity of the second layer 2 is 91 GR / cm 3 , and the third layer 3 is 70 GR / cm 3 .
특히, 상기 기저층(1)은 그 밑면에 다수의 돌출부(4)가 형성되어 있는데, 이와 같은 돌출부(4)에 의해 본 발명에 따른 차음재가 건축시공에 사용될 때에 슬래브와 이 차음재 사이에 공기층을 생성하게 되어, 단열효과는 물론 소음감소 및 표면적 증대로 인한 흡음율의 증가효과를 얻을 수 있다. 도 1에서, 상기 돌출부(4)는 반구형상으로 나타나 있지만, 임의의 다른 형상, 예컨대 육각뿔대나, 사각뿔대, 또는 각기둥 형상을 가질 수 있음은 물론이다. In particular, the base layer (1) has a plurality of protrusions (4) formed on the bottom surface, by such a protrusion (4) generates an air layer between the slab and the sound insulation material when the sound insulation material according to the present invention is used in construction As a result, an insulation effect, as well as an increase in sound absorption due to noise reduction and surface area increase, may be obtained. In Fig. 1, the protrusions 4 are shown in a hemispherical shape, but may of course have any other shape, such as a hexagonal pyramid, a square pyramid, or a prismatic pole.
한편, 본 발명에서는 적어도 2층 또는 3층으로 적층된 차음재의 구조를 설명하고 도시하고 있지만, 필요에 따라 이들 층을 각각 여러 번 더 추가하여 함께 가압발포함으로써 형성될 수도 있다. 이에 따라, 차음효과 뿐만 아니라 강도면에서 더욱 향상되게 되는 것이다. On the other hand, the present invention has been described and illustrated the structure of the sound insulating material laminated in at least two or three layers, it may be formed by pressing and foaming together by adding these layers several times as necessary. Accordingly, it is to be further improved in terms of strength as well as sound insulation effect.
이상과 같이 본 발명에 의하면, 밀도가 다른 층들을 적어도 2층으로 적층하여 구성함으로써, 아래층으로의 소음전달을 방지할수 있음은 물론, 건축구조물에 적용될 때 그 위에 설치되는 배관과 바닥재 등의 하중을 견딜 수 있는 강도를 갖는 차음재를 제공하게 된다. According to the present invention as described above, by stacking at least two layers with different densities, it is possible to prevent noise transmission to the lower floor, as well as to load the pipes and flooring materials installed thereon when applied to the building structure. It is to provide a sound insulation material having a strength that can withstand.
또한, 기저층의 밑면에 형성된 돌출부들 사이에 공기층을 형성하게 되어, 단열은 물론 소음감소 및 흡음율의 증가효과를 얻을 수 있다.In addition, since the air layer is formed between the protrusions formed on the bottom of the base layer, it is possible to obtain a heat insulating effect as well as noise reduction and sound absorption.
도 1은 본 발명의 한 실시예에 따른 차음재의 구조를 개략적으로 도시한, 밑에서 바라본 사시도이다. 1 is a perspective view from below, schematically showing the structure of a sound insulation material according to an embodiment of the present invention.
