Description

불연성의 흡음 및 단열 패널{INFLAMMABLE PANEL HAVING THERMAL AND SOUND INSULATION PROOERTIES}Non-combustible sound absorption and insulation panels {INFLAMMABLE PANEL HAVING THERMAL AND SOUND INSULATION PROOERTIES}

본 발명은 불연성의 흡음 및 단열 패널에 관한 것으로, 더욱 상세하게는 발포유리 과립 및 무기질 바인더를 포함함으로써, 친환경성, 경량성, 내화성, 단열성, 흡음성 및 가공성이 우수한 불연성의 흡음 및 단열 패널에 관한 것이다.The present invention relates to a non-combustible sound-absorbing and insulating panel, and more specifically, to a non-combustible sound-absorbing and insulating panel that contains foam glass granules and an inorganic binder and is therefore eco-friendly, lightweight, fire-resistant, heat-insulating, sound-absorbing and processable. will be.

주거환경 등의 개선을 위해 방음재와 단열재의 수요가 급증하고 있다. 건축용 단열재 또는 방음재의 용도에 사용되는 스티로폼은 가볍고 단열 및 방음 효과가 양호하나, 내구성이 약하고, 발화 및 인화가 잘되므로 화재 발생시에는 유독가스를 발생하기 때문에 인명 피해가 큰 단점이 있으며, 최근에는 그의 사용이 제한되고 있다.The demand for soundproofing and insulation materials is rapidly increasing to improve residential environments. Styrofoam, which is used for building insulation or soundproofing, is light and has good insulation and soundproofing effects, but has the disadvantage of being weak in durability, easily igniting and igniting, and generating toxic gas in the event of a fire, resulting in significant casualties. Recently, its Use is restricted.

또한, 건축용 단열재나 방음재 등으로 많이 사용되는 유리섬유(glass fiber) 등은 화재 등의 위험으로부터 안전하나, 대기중에 노출될 경우 유리섬유의 비산으로 인체에 유해한 침상의 먼지가 발생할 가능성이 있고, 시공할 때 유해한 먼지가 발생하여 시공 과정 중의 작업자의 건강에 나쁜 영향을 끼칠 염려가 있으며, 재질의 노화에 의해 발생하는 분진 등이 인체에 유해하다는 것이 판명됨에 따라 그 사용이 점차 줄어들고 있다.In addition, glass fiber, which is widely used as building insulation and soundproofing material, is safe from risks such as fire, but when exposed to the air, the scattering of glass fiber may generate bed dust that is harmful to the human body. There is concern that harmful dust may be generated during construction, which may have a negative impact on the health of workers during the construction process, and as it has been proven that dust generated by aging materials is harmful to the human body, its use is gradually decreasing.

또한, 폐목재를 활용한 목재는 친환경적인 장점이 있으나, 화재에 취약하고, 무엇보다도 흡음재 또는 단열재로서 성능이 떨어지는 문제점이 있으며, 폐목재 수급의 원활성에 애로가 있다.In addition, wood made from waste wood has the advantage of being environmentally friendly, but it is vulnerable to fire, and above all, it has the problem of poor performance as a sound absorbing or insulating material, and there are difficulties in smooth supply and demand of waste wood.

또한, 시멘트 콘크리트 소재를 흡음재로 적용하는 경우도 있으나, 시멘트 콘크리트 재질의 흡음재는 비중이 커서 제품이 무거우며, 시공성이 나쁘고, 개구율 그리고 다공질 구조 확보가 어려워 흡음 성능이 충분하지 않은 문제점이 있다.In addition, there are cases where cement concrete material is applied as a sound absorbing material, but the specific gravity of cement concrete sound absorbing material is large, so the product is heavy, constructability is poor, and it is difficult to secure the opening ratio and porous structure, so there are problems with insufficient sound absorbing performance.

종래 US 특허 제9,018,139호에서는 폐유리와 규산나트륨의 수화물을 혼합하고, 이를 750~1000℃의 고열로 성형하여 패널을 제조하는 방법이 제안되었는바, 이러한 패널은 경도가 높아 작은 충격에도 파손율이 높고, 온도에 따른 열팽창에 의한 파손 역시 많다는 단점이 있었다.Previously, US Patent No. 9,018,139 proposed a method of manufacturing a panel by mixing waste glass and a hydrate of sodium silicate and molding it at a high temperature of 750~1000℃. These panels have a high hardness and have a high breakage rate even under small impacts. The disadvantage was that it was high and there was a lot of damage due to thermal expansion depending on temperature.

한편, 시멘트 등과 같은 무기 바인더를 사용하여 성형한 패널 역시 제안되었으나, 제품의 경량성이 좋지 못하고, 작은 충격에도 쉽게 파손된다는 문제가 있었다. Meanwhile, panels molded using inorganic binders such as cement have also been proposed, but there are problems in that the products are not lightweight and are easily damaged by small impacts.

따라서, 본 발명의 목적은 발포유리 과립과 무기질 바인더를 사용함으로써, 경량성, 흡음성, 단열성, 내화성을 개선하면서도, 친환경성이 우수하며, 고열의 성형과정이 없어 고경도에 의한 파손율을 개선할 수 있는 불연성의 흡음 및 단열 패널을 제공하는 데 있다. Therefore, the purpose of the present invention is to improve lightness, sound absorption, insulation, and fire resistance by using foamed glass granules and an inorganic binder, while being excellent in eco-friendliness and improving the breakage rate due to high hardness without a high-temperature molding process. The goal is to provide non-combustible sound-absorbing and insulating panels.

본 발명의 불연성의 흡음 및 단열 패널에 의하면, 경량성, 흡음성, 단열성, 내화성 및 친환경성이 우수하고, 화재시 유독가스의 발생이 없으며, 제조단가가 낮고, 고경도에 의한 파손율이 개선된다는 장점이 있다.According to the non-combustible sound-absorbing and heat-insulating panel of the present invention, it is excellent in light weight, sound absorption, insulation, fire resistance and eco-friendliness, does not generate toxic gases in case of fire, has a low manufacturing cost, and has an improved damage rate due to high hardness. There is an advantage.

이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.

본 발명의 불연성의 흡음 및 단열 패널은, 발포유리 과립 및 무기질 바인더를 포함함으로써, 흡음, 단열, 경량 및 내화성이 우수하면서도, 친환경적이고, 종래 열성형 접합 제품 그리고 무기질 바인더 성형 제품들의 고경도로 인한 파손율이 높다는 문제점을 해소한다는 데 가장 큰 특징이 있다.The non-combustible sound-absorbing and heat-insulating panel of the present invention contains foamed glass granules and an inorganic binder, so it has excellent sound absorption, insulation, light weight and fire resistance, is environmentally friendly, and is resistant to damage due to the high hardness of conventional thermoformed bonded products and inorganic binder molded products. The biggest characteristic is that it solves the problem of high rates.

이러한 본 발명의 불연성의 흡음 및 단열 패널은, 발포유리 과립 및 무기질 바인더를 포함하여 제작되는 베이스 패널;을 포함하되, 상기 무기질 바인더는 유기계 바인더, 셀룰로오스, 증점제 및 무기계 바인더를 포함하는 것을 특징으로 한다.The non-combustible sound-absorbing and heat-insulating panel of the present invention includes a base panel manufactured including foamed glass granules and an inorganic binder, wherein the inorganic binder includes an organic binder, cellulose, a thickener, and an inorganic binder. .

먼저, 발포유리(foamed glass)는 유리에 균질한 기공을 발포시켜 유리 자체의 물성과 기조직에 기인하는 물성을 동시에 가지게 하는 소재이다. 아울러, 상기 발포유리는, 폐기된 유리 등을 원료로 하므로, 폐자원의 재활용 및 폐기 후의 재활용이 가능한 친환경 소재이다. 상기 발포유리는 균질한 기포에 의해 높은 경량성을 가지며, 소음과 진동을 차단하고 흡수하는 높은 흡/차음성이 있고, 그 외, 보냉, 보온의 단열성, 높은 내화성 및 불연성, 강 내산성 및 강 내식성이 있다는 특성이 있으며, 가공이 용이하다는 장점이 있다. First, foamed glass is a material that foams homogeneous pores in glass so that it has both the physical properties of the glass itself and the physical properties resulting from the structure. In addition, since the foamed glass is made from discarded glass, etc., it is an eco-friendly material that can be recycled as waste resources and after disposal. The foamed glass has high lightness due to homogeneous bubbles, has high absorption/sound insulation properties to block and absorb noise and vibration, and also has cold and warm insulation properties, high fire resistance and incombustibility, strong acid resistance, and strong corrosion resistance. It has the advantage of being easy to process.

본 발명에서 사용하는 발포유리 과립이란, 직경 0.2~20mm의 크기를 갖는 발포유리를 의미하는 것으로, 상기 발포유리 과립은 종래 시판되는 제품 중 어떠한 것이라도 사용 가능하다.The foamed glass granules used in the present invention refer to foamed glass having a diameter of 0.2 to 20 mm, and the foamed glass granules can be any of the conventionally sold products.

상기 무기질 바인더는 내화성이 우수하고, 화재시 유독가스의 배출이 없는 것은 물론, 발포유리 과립을 효과적으로 결합시키는 재료이다. The inorganic binder has excellent fire resistance, does not emit toxic gases in the event of a fire, and is a material that effectively binds foam glass granules.

이러한 무기질 바인더로는 유기계 바인더, 셀룰로오스, 증점제 및 무기계 바인더를 포함하는 것을 사용함이 바람직한데, 이러한 구성의 무기질 바인더는 불연성의 흡음 및 단열 패널의 고경도로 인한 파손율을 현저히 낮춰줄 수 있기 때문이다. 즉, 종래 고경도를 갖는 무기질의 불연성의 흡음 및 단열 패널의 경우 파손율이 높아 그 단가가 높고, 시공성과 운반성이 좋지 못하다는 단점이 있었으나, 본 발명은 이러한 무기질 바인더의 사용으로 상기한 단점을 모두 개선하는 것이다.It is preferable to use an inorganic binder containing an organic binder, cellulose, a thickener, and an inorganic binder, because the inorganic binder of this composition can significantly reduce the breakage rate due to the high hardness of the non-combustible sound-absorbing and insulating panel. That is, in the case of conventional inorganic, non-combustible sound-absorbing and insulating panels with high hardness, there were disadvantages such as high breakage rate, high unit cost, and poor constructability and transportability, but the present invention overcomes the above-described disadvantages by using such an inorganic binder. is to improve everything.

이때, 상기 유기계 바인더로는 아크릴공중합체, 비닐아세테이트-에틸렌 공중합체 및 폴리비닐알코올 중 선택된 1종 이상의 것을 사용할 수 있는바, 상기 유기계 바인더는 발포유리 과립 간 점착력을 높여준다. At this time, the organic binder may be one or more selected from acrylic copolymer, vinyl acetate-ethylene copolymer, and polyvinyl alcohol. The organic binder increases adhesion between foam glass granules.

상기 무기계 바인더는 포틀랜드시멘트, 소성석회 및 석고 중 1종 이상의 것을 사용할 수 있는바, 점결력을 높임은 물론, 내화성을 개선해주며, 고경도로 인한 파손율를 낮추는 데 도움을 준다. The inorganic binder can be one or more of Portland cement, calcined lime, and gypsum, and not only increases cohesive strength, but also improves fire resistance and helps reduce the breakage rate due to high hardness.

상기 셀룰로오스는 HPMC(hydropropyl methyl cellulose), HEMC(hydroethyl methyl cellulose), PMC(propyl methyl cellulose) 및 EMC(ethyl methyl cellulose) 중 1종 이상의 것을 사용할 수 있는바, 발포유리 과립 간 오픈셀을 형성토록 도와 더욱 개선된 흡음, 단열 성능을 갖도록 하며, 고경도로 인한 파손율을 낮춰 준다. The cellulose can be one or more of HPMC (hydropropyl methyl cellulose), HEMC (hydroethyl methyl cellulose), PMC (propyl methyl cellulose), and EMC (ethyl methyl cellulose), which helps form open cells between foam glass granules. It provides improved sound absorption and insulation performance, and reduces the breakage rate due to high hardness.

상기 증점제는 무기계 증점제를 사용함으로써, 화재로부터 안정토록 하며, 예시적으로 마그네슘 알루미노 실리케이트 등을 사용할 수 있는바, 이를 제한하지 않는다.The thickener is made to be stable against fire by using an inorganic thickener. For example, magnesium alumino silicate, etc. can be used, but this is not limited.

이때, 상기 무기질 바인더의 조성비는 유기계 바인더 30~40중량%, 셀룰로오스 5~8중량%, 증점제 3~6중량% 및 잔부의 무기계 바인더로 되는 것으로, 이러한 조성비를 벗어날 경우 우수한 내화성, 단열성, 흡음성 등을 유지할 수 없음은 물론, 파손율을 낮출 수 없다는 문제가 있기 때문이다.At this time, the composition ratio of the inorganic binder is 30 to 40% by weight of organic binder, 5 to 8% by weight of cellulose, 3 to 6% by weight of thickener, and the balance of inorganic binder. If this composition ratio is exceeded, excellent fire resistance, heat insulation, sound absorption, etc. This is because there is a problem that not only cannot be maintained, but the damage rate cannot be lowered.

아울러, 본 발명에서 상기 베이스 패널은 발포유리 과립 100중량부에 대하여, 상기 무기질 바인더를 10~50중량부를 포함하는 것으로, 무기질 바인더의 함량이 너무 낮으면 발포유리 과립 간의 점착력이 좋지 못하고, 과량이 되면 경량성 및 흡음성이 저하되는 단점이 있기 때문이다. In addition, in the present invention, the base panel contains 10 to 50 parts by weight of the inorganic binder based on 100 parts by weight of the foamed glass granules. If the content of the inorganic binder is too low, the adhesion between the foamed glass granules is poor, and if the content is too low, the adhesion between the foamed glass granules is poor. This is because there is a disadvantage in that lightness and sound absorption are reduced.

또한, 본 발명의 베이스 패널은 그 두께를 제한하지 않는다. 아울러, 베이스 패널의 제조시에는 물을 더 혼합하여 적정 압축, 성형한 후, 건조하는 것으로, 소량의 물이 더 포함될 수 있음은 당연하다. Additionally, the base panel of the present invention is not limited in its thickness. In addition, when manufacturing the base panel, additional water is mixed, appropriately compressed, molded, and then dried, so it is natural that a small amount of water may be added.

상기와 같이 구성되는 본 발명의 불연성의 흡음 및 단열 패널을 구성하는 베이스 패널은 앞서 설명된 바와 같이, 흡음, 단열, 경량 및 내화성이 우수하면서도, 친환경적이고, 상기한 조성의 무기질 바인더의 사용을 통해 고경도로 인한 파손율을 낮출 수 있다는 장점이 있다.As described above, the base panel constituting the non-combustible sound-absorbing and heat-insulating panel of the present invention configured as described above is excellent in sound-absorbing, heat-insulating, lightweight and fire-resistant, and is environmentally friendly through the use of an inorganic binder of the above-described composition.

본 발명의 불연성의 흡음 및 단열 패널은 상기한 베이스 패널을 포함함으로써, 흡음성 및 단열성이 우수하여 흡음소재 또는 단열소재로서 다양한 분야에 응용될 수 있으며, 기존의 콘크리트 재질의 흡음재, 유리섬유 재질의 흡음재와 달리 시공과정 중의 편의성이 크게 개선되는 효과를 지난다. 또한, 기존의 흡음재와 비교하여 친환경성이 우수하고, 제조단가가 낮으며, 대폭 경량화됨은 물론, 각종 물성 역시 향상되어 파손율 역시 낮출 수 있다는 장점이 있다. The non-combustible sound-absorbing and insulating panel of the present invention includes the above-described base panel, so it has excellent sound-absorbing and insulating properties and can be applied to various fields as a sound-absorbing or insulating material.

It may be configured.

이때, 상기 무기질 보드로는 종래 일반적인 흡음재로 사용되는 목보시멘트보드(wool wool cement board), 글라스울 보드 및 락울 보드 중 1종의 것을 사용할 수 있음은 당연하다. At this time, it is natural that one of the inorganic boards, which are conventionally used as general sound absorbing materials, such as wool cement board, glass wool board, and rock wool board, can be used.

이러한 무기질 보드를 더 포함할 경우, 최소한의 무게만이 증가된 상태에서 불연성능 및 흡음성능은 더욱 높일 수 있다는 장점이 있다.When additional inorganic boards are included, the incombustibility and sound absorption performance can be further improved with only a minimal increase in weight.

또한, 본 발명에 의한 불연흡음단열패널은 상기 베이스 패널과 무기질 보드의 사이에 개재되는 다른 하나의 베이스 패널;을 더 포함할 수도 있는 것으로, 그 추가 실시를 제한하지 않는다.In addition, the non-combustible sound-absorbing insulation panel according to the present invention may further include another base panel interposed between the base panel and the inorganic board, and its further implementation is not limited.

이하, 본 발명에 의한 불연성의 흡음 및 단열 패널의 제조방법에 대하여 간단히 설명한다.Hereinafter, the method of manufacturing a non-combustible sound-absorbing and heat-insulating panel according to the present invention will be briefly described.

First, the raw materials foam glass granules and inorganic binder are mixed. And mix more water. At this time, the mixing ratio may be about 10 to 50 parts by weight of the inorganic binder and 50 to 150 parts by weight of water based on 100 parts by weight of the foamed glass granules, but this is not necessarily limited.

아울러, 필요에 따라 부재료인 대나무섬유, 마이크로 화이버, 닥나무 분말, 옥수수속대 분말 중 1종 이상을 더 혼합한다.In addition, if necessary, one or more of the auxiliary materials such as bamboo fiber, microfiber, mulberry tree powder, and corn cob powder are further mixed.

그리고 상기 혼합된 혼합물을 몰드에 주입하여 원하는 형태로 성형한다. 이때, 상기 성형은 패널 형태일 수 있으며, 그 두께는 3~50mm일 수 있으나, 이를 제한하지 않는다.Then, the mixed mixture is injected into a mold and molded into the desired shape. At this time, the molding may be in the form of a panel, and the thickness may be 3 to 50 mm, but this is not limited.
