본 발명은 건축물의 소음 차단 방지 구조 및 제조방법에 관한 것으로, 더욱 상세하게는 저주파에서 고주파 대역까지 흡음, 차음이 가능하여 공동주택에서의 생활소음이나 공장 등에서 기계음의 소음을 차단할 수 있는 판넬 구조 및 제조방법에 관한 것이다.The present invention relates to a noise blocking prevention structure and manufacturing method of a building, and more particularly, a panel structure that can absorb and insulate sound from low to high frequency bands to block living noise in apartment houses or mechanical noise in factories, etc. It relates to a manufacturing method.

아파트나 빌라 등 공동주택의 건물 구조체에 가해지는 소음은 사람의 보행, 문의 개폐, 기물의 이동이나 설비 기기의 가동 혹은 정지 등이 충격의 원인이 되어 발생되는 고체 전달음이 사방으로 전달되게 되고, 이로 인하여 건물 구조체의 표면을 진동시킬 뿐만 아니라, 공기 전달음으로 전화되어 주변의 사람들 귀에 들리게 될 때, 소음으로 인식되게 된다.As for the noise applied to the building structure of a multi-family house such as an apartment or a villa, the solid-transmission sound generated when a person walks, opens or closes a door, moves an object, or starts or stops a facility is the cause of the impact, and the sound is transmitted in all directions. Due to this, not only the surface of the building structure vibrates, but also when it is converted into air transmission sound and heard by people around it, it is recognized as noise.

특히, 요즘 시공되는 건축물에서, 그 건축물의 차음성의 향상은 단열성을 향상시키는 것 이상으로 고려되고 있다. 종래에는 따뜻하고 안락한 건축물, 여름과 겨울을 지나며 자연스럽게 발생되는 난방비 등의 비용이 절감될 수 있도록 하는 단열성과 내열성을 가진 건축물을 시공하는 것이 목표였다. 그러나 아파트와 같이 공동으로 집단적인 거주가 일반화된 대한민국의 경우, 층간소음으로 인하여 고통받는 거주자들이 늘고 있기에 차음 시설의 완비가 더욱 필요한 시공 사항으로 받아들여지고 있다.In particular, in buildings constructed these days, improvement in sound insulation properties of the buildings is considered more than improving insulation properties. Conventionally, the goal has been to construct a building with heat insulation and heat resistance that can reduce costs such as warm and comfortable buildings and heating costs that occur naturally during summer and winter. However, in the case of Korea, where communal living such as apartments is common, the number of residents suffering from inter-floor noise is increasing, so the completeness of sound insulation facilities is accepted as a construction matter that requires more.

또한, 제조 공장에서 발생되는 기계 소음에 의하여 주변에 피해를 주며, 이에 따라 요즘은 건축물을 시공할 때, 차음 시설을 설비하지 못하면 건축이 불가능한 정도로까지 규제가 있는 것이다. 따라서 종래에도 이러한 차음시설의 설비를 위해서 다양한 판넬들이 개발되고 있다. 널리 사용되고 있는 흡음 재료로는 glass wool과 폴리우레탄 폼, 발포 알루미늄, asphalt pad 등이 있다. Glass wool과 아스팔트 패드는 각각 흡음과 방진용으로 활용되고 있으나, glass wool은 인체에 해롭고 재활용이 되지 않는다는 단점이 있으며, 아스팔트 패드는 중량이 무거워 생활에서 활용이 어렵다. 또한, 폴리우레탄 폼의 경우 제조 단가가 비싸고 내수성이 약하다는 단점이 있으며, 발포 알루미늄의 경우에는 가격과 내구성에서 문제점이 존재하였다. 따라서, 최근에는 고분자 복합체를 이용하여 흡음의 효과를 향상시키거나 흡음재의 구조를 변경하여 흡음 효과를 극대화하려는 연구가 시도되고 있다.In addition, the machine noise generated in the manufacturing plant causes damage to the surroundings, and accordingly, when constructing a building, there are regulations to the extent that it is impossible to construct a building without installing a sound insulation facility. Therefore, in the prior art, various panels have been developed for the facilities of such sound insulation facilities. The widely used sound-absorbing materials include glass wool, polyurethane foam, foamed aluminum, and asphalt pad. Glass wool and asphalt pad are each used for sound absorption and vibration protection, but glass wool is harmful to the human body and has the disadvantage that it cannot be recycled. In addition, in the case of polyurethane foam, there are disadvantages in that the manufacturing cost is high and water resistance is weak, and in the case of foamed aluminum, there are problems in price and durability. Therefore, recently, studies have been attempted to improve the sound absorption effect by using a polymer composite or to maximize the sound absorption effect by changing the structure of the sound absorption material.

이러한 배경 하에, 본 발명자들은 흡음면과, 소음저감면, 차음면 및 외측면으로 구성되는 다층 형태의 소음차단블록판넬이 뛰어난 흡음 성질을 가지면서도 열전도율이 낮아 우수한 난연 성질을 나타내는 것을 확인하여 본 발명을 완성하였다. Under this background, the present inventors confirmed that a multi-layered noise blocking block panel composed of a sound-absorbing surface, a noise reducing surface, a sound insulating surface and an outer surface exhibits excellent flame retardant properties due to low thermal conductivity while having excellent sound absorption properties. was completed.

The styrenic-vinyl cyan-based copolymer preferably has a weight average molecular weight of 150,000 or more, more preferably 15 About 200,000 is good, and it is more preferable to have a low melt viscosity suitable for foam release extrusion. For example, the Mn/Mw value is 2.0 or more, preferably 2.5-5.0, and the molecular weight distribution is wide, so it is good to include a certain amount of low molecular weight products. In the present invention, it is more preferable that the styrene-based-vinyl cyan-based copolymer has a composition ratio of 60-80 wt % and 20-40 wt % of styrene-based and vinyl cyan-based copolymers, respectively. When the content of vinyl cyanide is increased, the thermal stability of the polymer is lowered, and when the content of styrene is increased, the rigidity of the product may be lowered during the foaming process.

The foamed resin of the present invention is 100 parts by weight of a resin composed of 40 to 60% by weight of a styrenic-vinyl cyan-based copolymer and 40 to 60% by weight of an acrylic rubber-vinyl cyan-based-styrene-based terpolymer and 0.5 to 5 parts by weight of a foaming agent. may include wealth.

스티렌계 비닐시안계 공중합체의 함량이 상기 범위 미만인 경우에는, 발포된 프로파일의 압출성이 저하되어 압출 도중 서징 현상이 발생하기 쉽고, 굴곡 및 인장 강도가 저하될 수 있으며, 온도에 따른 수축률이 커져 파손될 가능성이 높아진다. 또한, 스티렌계 비닐시안계 공중합체의 함량이 상기 범위 초과일 경우에는, 발포 후 충격 강도가 약해져 가공 중 파손될 우려가 있다.When the content of the styrene-based vinyl cyanide copolymer is less than the above range, the extrudability of the foamed profile is lowered, so that a surging phenomenon is easy to occur during extrusion, bending and tensile strength may be reduced, and the shrinkage rate according to temperature is increased. increased likelihood of being damaged. In addition, when the content of the styrene-based vinyl cyanide copolymer exceeds the above range, the impact strength after foaming is weakened, and there is a risk of damage during processing.

스티렌-비닐시안계 공중합체, 아크릴고무-비닐시안계-스티렌계 삼원 공중합체의 조성물을 혼합 후, 압출기를 이용하여 펠렛 형태의 수지를 제조할 수 있다. 이때 상기 발포제를 섞지 않는다. 이때 발포제를 섞은 후 압출을 하게 되면 펠렛 압출 단계에서 발포가 미리 일어날 수 있다. 상기 제조된 수지 펠렛을 다시 믹서를 이용하여 상기 발포제와 블렌딩한다. After mixing the composition of the styrene-vinyl cyan-based copolymer and the acrylic rubber-vinyl cyan-based-styrene-based terpolymer, the resin in the form of pellets can be prepared using an extruder. At this time, do not mix the foaming agent. At this time, if extrusion is performed after mixing the foaming agent, foaming may occur in advance in the pellet extrusion step.

Preferably, the foaming agent has a thermal conductivity of 0.2 W/mK or less, specifically 0.1-0.2 W/mK, so that heat loss can be minimized by increasing thermal insulation properties.

상기 발포제의 함량이 지나치게 적을 경우 최종 제품인 차음면(130)의 단열성과 차음성이 저하될 수 있으며, 상기 발포제의 함량이 많을 경우 차음성은 향상시킬 수 있으나 압출기 내부에서 변화가 커져서 상업적인 압출 발포를 하기가 어렵고, 압출 발포를 하더라도 인장강도가 저하되기 쉽다.If the content of the foaming agent is too small, the thermal insulation and sound insulation properties of the sound insulating surface 130, which is the final product, may be reduced. It is difficult to do, and even if extrusion foaming is performed, the tensile strength is likely to decrease.

발포제는 비중이 0.5 g/cc에서 1.0 g/cc 것이 바람직하다. 발포체의 비중이 지나치게 낮을 경우, 압출 발포에 의해 제품 생산이 어려울 뿐만 아니라 강도가 저하되어 소음차단블록판넬(100)가의 조립시 파손이 일어날 가능성이 상승하게 된다.The blowing agent preferably has a specific gravity of 0.5 g/cc to 1.0 g/cc. When the specific gravity of the foam is too low, it is difficult to produce a product by extrusion foaming, and the strength is lowered, so that the possibility of damage during assembly of the noise blocking block panel 100 increases.
