본 발명은 흡음, 방음, 차음 소재로 사용되는 흡음재 및 그 제조방법에 대한 것으로, 특히 건축용 내, 외장재로서의 흡음재, 천장재, 타일재 등으로 사용될 수 있는 불연성의 뿜칠재, 흡음재와 그 제조방법 및 뿜칠재를 이용한 흡음벽면 시공방법에 관한 것이다.The present invention relates to a sound absorbing material used as a sound absorbing, soundproofing, and soundproofing material, and a method for manufacturing the same. The present invention relates to a sound absorbing wall construction method using lacquer.
흡음재는 그 구조에 따라서는 다공질 흡음재와 판상(板狀) 흡음재로 구분된다. 다공질 흡음재는 표면과 내부에 작은 기포(氣泡) 또는 가는 관(管) 모양의 구멍이 많이 있는데, 이 구멍 속의 공기가 음파에 의해 진동하고 이 때 생긴 마찰 때문에 소리에너지가 열에너지로 바뀌어 흡수된다. 흡음 성능은 다공질의 정도와 재료의 두께에 따라 달라진다. 판상 흡음재는 얇은 판을 진동시켜 소리에너지를 열에너지로 바뀌도록 하는 흡음재이다. 본 발명은 전자와 관련된 것이다.The sound absorbing material is classified into a porous sound absorbing material and a plate-shaped sound absorbing material depending on its structure. Porous sound absorbing material has many small bubbles or thin tube-shaped holes on the surface and inside, and the air in these holes vibrates by sound waves, and the sound energy is converted into thermal energy and absorbed by the friction generated at this time. Sound absorption performance depends on the degree of porosity and the thickness of the material. A plate-shaped sound absorbing material is a sound absorbing material that vibrates a thin plate to convert sound energy into thermal energy. The present invention relates to the former.
흡음재의 재료로는 폴리에스테르가 널리 사용되고 있는 데, 이는 불연성이 떨어진다는 큰 문제점을 가지고 있다. 불연성 흡음재로는 석고보드, 석면시멘트판 등이 사용되나 잘 부서지거나 인체에 유해하고, 고급스러운 인테리어에는 부적합하다는 단점이 있다.Polyester is widely used as a sound absorbing material, which has a large problem of incombustibility. As a non-combustible sound absorbing material, gypsum board, asbestos cement board, etc. are used, but it has a disadvantage of being broken or harmful to the human body and unsuitable for a luxurious interior.
본 발명의 목적은 인체에 무해하고 만들기 쉬우면서도 불연성이 뛰어난 불연성의 흡음재를 제공하는 데 있다.An object of the present invention is to provide a non-combustible sound absorbing material that is harmless to the human body, easy to make, and excellent in non-combustibility.
본 발명의 다른 목적은 흡음 기능을 가지면서도 고급의 건축 내, 외장재로 사용될 수 있는 불연성의 흡음재를 제공하는 데 있다.Another object of the present invention is to provide a non-combustible sound absorbing material that can be used as an exterior material in a high-grade building while having a sound absorbing function.
본 발명의 또 다른 목적은 본 발명에 따른 불연성의 흡음재 제조방법을 제공하는 데 있다.Another object of the present invention to provide a non-combustible sound absorbing material manufacturing method according to the present invention.
본 발명의 또 다른 목적은 흡음 성능을 얻을 수 있는 뿜칠재를 제공하는 데 있다.Still another object of the present invention is to provide a foaming material which can obtain sound absorption performance.
본 발명의 또 다른 목적은 본 발명에 따른 뿜칠재를 이용한 흡음벽면 시공방 법을 제공하는 데 있다.Still another object of the present invention is to provide a sound absorbing wall construction method using the blowing material according to the present invention.
본 발명에 따른 흡연재 제조방법은 흙 100중량부에 소다를 10중량부 이하로 첨가하고 물로 반죽하여 반죽물을 만드는 반죽단계, 상기 반죽물을 틀에 넣고 가압하여 성형하여 성형물을 만드는 성형단계, 상기 성형물을 65℃ 이상으로 가열하여 상기 소다에서 이산화탄소를 발생시켜 상기 성형물 내부에 기공을 형성하는 기공형성단계 및 상기 기공이 형성된 상기 성형물을 건조하는 건조단계를 포함하는 구성을 가진다.Smoking material manufacturing method according to the present invention is a dough step of making a dough by adding 10 parts by weight or less to 100 parts by weight of soil and kneading with water, a molding step of forming the molding by pressing the dough into a mold and molding; The molding is heated to 65 ° C. or higher to generate carbon dioxide from the soda to form pores in the molding, and a composition including a drying step of drying the molding in which the pores are formed.
경우에 따라, 상기 반죽단계에 크기가 2 ~ 6㎜인 경량골재를 10 ~ 15중량부 더 첨가하여 반죽할 수 있다.In some cases, the dough may be kneaded by further adding 10 to 15 parts by weight of the light aggregate having a size of 2 to 6 mm.
상기 반죽단계에 크기가 2 ~ 6㎜인 펄프, 나무뿌리 또는 폐타이어 고무를 25 ~ 30중량부 더 첨가하여 반죽하는 것이 바람직하다.It is preferable to knead by further adding 25 to 30 parts by weight of pulp, tree root or waste tire rubber having a size of 2 to 6 mm in the kneading step.
경우에 따라, 상기 반죽단계에 전분 5 ~ 10중량부 더 첨가할 수 있다.In some cases, 5 to 10 parts by weight of starch may be further added to the kneading step.
상기 흙은 황토 또는 백토를 사용하는 것이 좋고, 경우에 따라 둘을 혼합하여 사용할 수도 있다.The soil is good to use ocher or clay, may be used by mixing the two in some cases.
또, 경우에 따라서는 황토, 백토 또는 황토와 백토를 섞은 것을 여타의 다른 흙과 혼합하여 사용할 수 있음은 물론이다.In some cases, ocher, clay or a mixture of ocher and white clay may be mixed with other soils.
경우에 따라, 상기 반죽단계에 소금 3 ~ 5중량부 더 첨가할 수 있다. 소금은 펄프나 전분 등 유기물의 방부재의 역할을 한다.In some cases, 3 to 5 parts by weight of salt may be further added to the kneading step. Salt acts as a barrier to organic matter such as pulp and starch.
상기 기공형성단계에는 상기 성형물의 온도를 80℃ ~ 95℃를 유지하는 것이 바람직하다.In the pore forming step, it is preferable to maintain the temperature of the molding 80 ℃ ~ 95 ℃.
상기 건조단계에는 상기 성형물을 90℃ ~ 100℃의 온도로 건조하면서 상기 성형물에 잔류하는 소다에서 이산화탄소를 발생시켜 상기 성형물 내부에 기공을 더 형성하는 것이 더욱 좋다.In the drying step, it is more preferable to further form pores in the molding by generating carbon dioxide from the soda remaining in the molding while drying the molding to a temperature of 90 ℃ ~ 100 ℃.
상기 반죽단계에 크기가 2 ~ 6㎜인 경량골재 10 ~ 15중량부와 크기가 2 ~ 6㎜인 펄프 25 ~ 30중량부를 더 첨가하여 반죽할 수 있다.10 to 15 parts by weight of lightweight aggregate having a size of 2 to 6 mm and 25 to 30 parts by weight of pulp having a size of 2 to 6 mm may be added to the kneading step.
상기 반죽단계에 크기가 2 ~ 6㎜인 한지를 25 ~ 30중량부 더 첨가하여 반죽할 수 있다.The dough may be kneaded by further adding 25 to 30 parts by weight of Hanji 2 ~ 6㎜ in size.
상기 소다는 중탄산 소다인 것이 바람직하다.The soda is preferably soda bicarbonate.
본 발명에 따른 천연 불연 흡음재는 위에서 설명한 본 발명의 방법에 따라 만들어진다.The natural non-combustible sound absorbing material according to the invention is made according to the method of the invention described above.
위에서 설명한 반죽물은 건축물의 뿜칠재로 사용될 수 있다.The dough described above can be used as a building material for spraying.
위에서 설명한 반죽물을 뿜칠재로 사용하고자 하는 경우에는 경우에 따라 소다 없이 흙과 펄프 또는 흙과 한지를 필수 구성요소로 할 수 있다. 이 경우, 뿜칠재를 시공하고자하는 벽면에 부착 후 가열 하지 않고 자연 건조하여도 된다. In the case where the above-mentioned dough is to be used as the material to be sprayed, in some cases, soil and pulp or soil and paper can be used as essential components without soda. In this case, the sprayed material may be naturally dried without heating after being attached to the wall to be constructed.
나머지 뿜칠재에 대한 설명은 앞의 반죽물에 대해 설명한 바와 같다.The remaining description of the material to be sprayed is as described for the dough.
소다가 첨가된 뿜칠재를 이용하는 경우의 흡음벽면 시공방법은 흙 100중량부에 소다를 10중량부 이하로 첨가하고 물로 반죽하여 만든 뿜칠재를 시공하고자 하는 벽면에 부착 후 상기 벽면에 부착된 상기 뿜칠재를 65℃ 이상으로 가열 후 건조하는 단계를 포함하는 것이 바람직하다. 물론, 이 경우에도 뿜칠재에 펄프나 한지 가 더 첨가되는 경우 가열과정 없이 자연건조 하여도 된다. 소다는 0.1중량부 이상으로 첨가하는 것이 바람직하며, 그 이하로 첨가되는 경우에도 65℃이상으로 가열되는 경우 이산화탄소 발생에 의해 흡음재의 표면과 내부에 기공형성은 되지만 큰 흡음 효과를 기대하기는 어렵다. 흙 100중량부에 소다가 10중량부 이상 너무 많이 첨가되는 경우 점착력, 강도 등에 문제가 생길 수 있고 단가가 증가되어 비현실적이다. 바람직하기로는 흙 100중량부에 소다는 1 ~ 5중량부 정도 첨가되는 것이 바람직하다.Sound absorbing wall surface construction method when using soda-added blowing material is attached to the wall surface after attaching the blowing material made by adding soda to 10 parts by weight or less to 100 parts by weight of soil and kneaded with water It is preferable to include the step of drying the lacquer after heating to 65 ℃ or more. Of course, in this case, if more pulp or paper is added to the material to be sprayed, it may be naturally dried without heating. Soda is preferably added in an amount of 0.1 parts by weight or more, and even if it is added below, it is difficult to expect a large sound absorbing effect, although the pores are formed on the surface and the inside of the sound absorbing material by the generation of carbon dioxide when heated to 65 ℃ or more. If soda is added in an amount of 10 parts by weight or more to 100 parts by weight of the soil, it may cause problems such as adhesive strength and strength, and the unit price is increased and is unrealistic. Preferably, 1 to 5 parts by weight of soda is preferably added to 100 parts by weight of soil.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 불연 흡연재 제조과정을 설명하기 위한 블록도이다.1 is a block diagram for explaining a process of manufacturing a non-combustible smoking material according to the present invention.
채취한 흙에서 굵은 돌이나 찌꺼기를 제거하고 약 200메시 등의 채로 쳐서 가늘고 고운 흙을 준비한다. 흙으로는 황토나 백토가 좋고, 둘을 혼합한 것이 사용될 수 있다. 황토나 백토가 아닌 다른 흙이 사용될 수 있음은 물론이다.Remove the coarse stone or debris from the collected soil and beat it with about 200 mesh to prepare fine and fine soil. The soil may be ocher or white clay, and a mixture of the two may be used. Of course, soil other than loess or white clay may be used.
준비된 흙에 소다, 바람직하게는 중탄산 소다를 흙 무게의 10% 이하, 바람직하기로는 1 ~ 5%의 범위로 첨가하고 물을 가하여 반죽하여 반죽물을 만든다. 반죽정도는 반죽물을 시멘트 벽면에 두께 20㎜ 정도로 부착한 상태에서 반죽물이 아래로 흘러내리지 않을 정도로 하면 된다.Soda, preferably bicarbonate, is added to the prepared soil in a range of 10% or less of the soil weight, preferably 1 to 5%, and kneaded by adding water to make a dough. The kneading degree may be such that the dough does not flow down while the dough is attached to the cement wall with a thickness of about 20 mm.
소다의 첨가량은 흙의 량에 따라 정해지며 여타의 재료의 첨가량에는 거의 영향을 받지 않는다. 중탄산 소다는 가열에 의해 이산화탄소를 발생하여 내부에 기공을 형성하는 역할을 하며, 유기물의 방부제 역할을 하기도 한다.The amount of soda is determined by the amount of soil and is hardly affected by the amount of other ingredients. Sodium bicarbonate generates carbon dioxide by heating to form pores therein, and also serves as an organic preservative.
바람직하게는 흙에 크기가 2 ~ 6㎜인 경량골재를 흙 무게의 10 ~ 15%를 더 첨가하여 반죽할 수 있다. 경량골재는 그 자체에 기공을 가지고 있는 것으로 흙의 사용량을 줄이고, 만들어지는 흡음재의 강도를 높일 수 있도록 해준다.Preferably, the lightweight aggregate having a size of 2 to 6 mm to the soil may be kneaded by adding 10 to 15% of the soil weight. Lightweight aggregates have pores on their own, reducing the amount of soil used and increasing the strength of the sound-absorbing materials produced.
본 발명의 흡음재 제조에 사용될 수 있는 경량골재로는 천연경량골재, 인공경량골재 및 공업부산물 등이 있다. 천연 경량골재에는 화산력(火山礫), 경석, 용암 등이 있는데, 경석이 많이 쓰인다. 인공 경량골재는 점토혈암(頁岩) 등을 고온으로 소성한 것으로서, 소성할 때에 균질하게 팽창발포 시킨 팽창점토 팽창혈암이다. 이는 천연산보다 강도가 크고, 알갱이 모양도 고르고 좋다. 공업부산물로서는 석탄재나 슬래그를 급랭하여 만든 팽창 슬래그가 있다. 또 천연 경량골재의 결점을 개량한 것으로는 표면을 시멘트 반죽으로 발라서 입형(粒形)을 좋게 하여 흡수율을 적게 한 표면가공품도 있다.Light weight aggregates that can be used in the sound absorbing material production of the present invention include natural lightweight aggregates, artificial lightweight aggregates and industrial by-products. Natural lightweight aggregates include volcanic forces (火山 礫), pumice, lava, and pumice is used a lot. The artificial lightweight aggregate is a sintered clay shale (頁岩) and the like at high temperature, and when sintered, it is expanded clay swelled rock expanded homogeneously and expanded. It is stronger than natural acid and has good grain shape. Industrial by-products include expanded slag produced by quenching coal ash or slag. Another shortcoming of natural lightweight aggregates is the use of surface-treated products that are coated with cement paste for better granularity and less water absorption.
또 경우에 따라 펄프를 바람직하게 2 ~ 6㎜정도의 길이로 세절하여 흙의 무게대비 25 ~ 30% 더 첨가하여 반죽할 수 있다. 펄프로는 한지를 만들 때 사용되는 닥나무 펄프가 적당하다. 한지 외에 솜 같은 종모섬유(種毛纖維)와 대나무, 짚, 갈대 등과 같은 벼과식물의 줄기, 마닐라삼의 줄기 등이 사용될 수 있다.In some cases, the pulp is preferably cut into lengths of about 2 to 6 mm and kneaded by adding 25 to 30% more to the weight of the soil. Pulp is suitable for the paper mulberry pulp, which is used to make Korean paper. In addition to Hanji, cotton wool fibers (種 毛 纖維), and stems of rice plants such as bamboo, straw, reeds, stems of manila hemp, etc. may be used.
이 펄프는 흙과 흙 사이를 연결하여 만들어지는 흡음재의 연결강도를 높여주는 역할을 한다. 경우에 따라 펄프 대신에 한지가 첨가될 수 있다. 펄프와 한지에는 그 자체에 미세한 구멍들이 무수히 형성되어 있기 때문에 기공을 형성하며, 흙 입자들이 그 구멍 속으로 침투되어 굳어짐으로써 이웃하는 흙 입자들 간의 연결강도를 증가시키는 역할도 한다.This pulp increases the connection strength of the sound absorbing material made by connecting the soil with the soil. In some cases, Hanji may be added instead of pulp. Pulp and Hanji form pores because they have a myriad of tiny holes in them, and they also increase the strength of connection between neighboring soil particles by infiltrating and solidifying soil particles.
이 경우 예를 들면, 흙 무게의 25 ~ 30% 무게의 펄프를 흙 무게의 70 ~ 75% 무게의 물에 풀어서 혼합하고, 이 것을 흙과 반죽하면 된다. 소다는 흙에 혼합하거나 물에 타서 혼합할 수 있다.In this case, for example, the pulp of 25 to 30% of the weight of the soil is dissolved in water of 70 to 75% of the weight of the soil, mixed, and kneaded with the soil. Soda can be mixed with soil or mixed with water.
경우에 따라 펄프 대신에 폐타이어 고무나 나무뿌리를 2 ~ 6㎜ 정도로 세절한 것을 사용할 수 있다.In some cases, instead of the pulp, waste tire rubber or wood roots can be used as small as 2 to 6 mm.
또 경우에 따라 흙 입자들 간의 점착력을 증가시키기 위해 흙 무게의 5 ~ 10% 중량의 범위에서 전분을 더 첨가할 수 있다. 전분은 물과 함께 55∼65℃ 이상의 온도로 가열되면 전분 입자가 급속하게 물을 흡수하여 팽윤하면서 반투명의 콜로이드(Colloid) 상태로 변하고 점착력이 높아진다. 그 후 건조되면 수분증발로 인해 딱딱해지면서 그 부피도 줄어들어 만들어지는 흡음재 내부에 기공을 형성한다.In some cases, starch may be further added in the range of 5 to 10% by weight of the soil to increase the adhesion between the soil particles. When the starch is heated to a temperature of 55 ~ 65 ℃ or more with water, the starch particles rapidly absorb the water and swell, changing to a translucent colloid (colloid) state and the adhesive force is high. After drying, it becomes hard due to moisture evaporation and its volume is reduced to form pores inside the sound absorbing material.
한편, 전분 등의 부식을 방지하기 위해 소금이 흙 무게의 3 ~ 5% 중량의 범위에서 더 첨가될 수 있다(단계 1).On the other hand, to prevent corrosion of starch and the like salt may be further added in the range of 3 to 5% by weight of the soil weight (step 1).
위에서 설명한 바와 같이 흙과 중탄산 소다(NaHCO3)를 기본 재료로 하고, 여기에 기타의 재료들을 만들고자하는 흡음재의 용도에 따라 선택적으로 선택하여 첨가하여 충분히 반죽하고, 반죽물을 만든 후에는 반죽물을 틀에 다져넣고 프레스 등으로 약 50Kg/㎠ 이상의 압력으로 가압하여 만들고자하는 보드형태로 성형하여 성형물을 만든다. 두께가 10㎜ 전후인 경우, 가압 압력은 50 ~ 55Kg/㎠, 두께가 20㎜ 인 경우, 가압 압력은 60 ~ 70Kg/㎠ 정도로 하면 되고, 두께가 증가됨에 따라 가압 압력도 두께에 비례하여 증가시키는 것이 좋다. 또, 경우에 따라 반죽물을 가압하는 가압력은 흡음재의 용도나 첨가물의 종류에 따라 가감될 수 있다. 그리고 흡음재가 보드 형태로 만들어지는 경우 그 두께는 통상 5㎜ ~ 50㎜ 정도로, 더 바람직하기로는15㎜ ~ 45㎜로 만들어진다. 경우에 따라 100㎜ 이상의 두께로 만들어질 수 있음은 물론이다(단계 2).As described above, soil and sodium bicarbonate (NaHCO 3 ) are used as the basic materials, and optional additions are made according to the purpose of the sound absorbing material to make other materials. It is molded into a board shape to be made by pressing into a mold and pressing at a pressure of about 50Kg / ㎠ or more with a press or the like to make a molded product. When the thickness is around 10mm, the pressurization pressure is 50 ~ 55Kg / ㎠, when the thickness is 20mm, the pressurization pressure is about 60 ~ 70Kg / ㎠ to increase the pressure in proportion to the thickness as the thickness increases It is good. In addition, in some cases, the pressing force for pressurizing the dough may be reduced according to the use of the sound absorbing material or the kind of the additive. And when the sound absorbing material is made in the form of a board, its thickness is usually made of about 5 mm to 50 mm, more preferably 15 mm to 45 mm. In some cases, it may be made of a thickness of 100mm or more (step 2).
성형물이 완성된 후에는 이 성형물을 가열하여 65℃ 이상으로 승온 시킨다. 성형물의 표면뿐만 아니라 그 내부의 전체가 65℃ 이상으로 될 수 있도록 성형물을 충분히 가열한다. 성형물의 온도는 전체가 80℃ ~ 95℃로 승온된 뒤 1분 이상, 바람직하기로는 30분 이상 유지하는 것이다. 물론, 95℃ 이상으로 가열하여도 된다. 성형물이 가열되면 성형물 내부에 함유되어 있던 중탄산 소다는 2NaHCO3 → Na2CO3＋H2O＋CO2와 같은 화학반응을 일으켜 이산화탄소와 물 및 탄산나트륨 무수물을 발생시키고, 이에 따라 성형물 내부에는 이산화탄소 등에 의한 기공이 형성된다(단계 3).After the molding is completed, the molding is heated to be heated to 65 ° C or higher. The molding is sufficiently heated so that not only the surface of the molding but the whole inside thereof can be at least 65 ° C. The temperature of the molded product is maintained for 1 minute or more, preferably 30 minutes or more after the whole temperature is raised to 80 ° C to 95 ° C. Of course, you may heat above 95 degreeC. When the molding is heated, soda bicarbonate contained in the molding causes a chemical reaction such as 2NaHCO 3 → Na 2 CO 3 + H 2 O + CO 2 to generate carbon dioxide, water, and sodium carbonate anhydride. Is formed (step 3).
위와 같이 하여 기공이 형성된 성형물을 건조하면 건축물의 내, 외장재로서 흡음재, 방음재 등으로 사용할 수 있는 본 발명에 따른 불연 천연 흠음재가 얻어진다. 상온에서의 건조는 6일 이상 충분히 건조하는 것이 좋다.Drying the molded article formed with pores as described above is obtained a non-combustible natural flaw material according to the present invention that can be used as a sound absorbing material, a soundproofing material and the like as the interior, exterior material of the building. Drying at room temperature is preferably dried for at least 6 days.
바람직하기로는 실내 온도가 90℃ ~ 100℃의 건조실에서 두께가 5㎜인 것은 3 ~ 4시간, 두께가 10㎜인 것은 4 ~ 5시간 정도 건조하는 것이 좋고, 두께가 20㎜ 내지 100㎜인 경우 6시간 ~ 1일정도 건조하는 것이 좋다. 두께가 30㎜ 이상인 경 우 약 12시간 이상 건조하는 것이 좋다. 물론, 건조 시간이 이 범위를 벗어나는 경우 건조에 따른 효과는 다소 떨어지지만 건조 시간만큼의 효과는 생긴다. 이 경우 성형물에 잔류하는 소다에서 이산화탄소를 발생시켜 상기 성형물 내부에 기공을 더 형성될 수 있다(단계 4).Preferably, in a drying chamber having a room temperature of 90 ° C. to 100 ° C., the thickness of 5 mm should be dried for 3 to 4 hours, and the thickness of 10 mm should be dried for about 4 to 5 hours, and the thickness is 20 mm to 100 mm. It is recommended to dry for 6 hours to 1 day. If the thickness is 30 mm or more, it is recommended to dry for at least 12 hours. Of course, if the drying time is out of this range, the effect of drying is slightly reduced, but the effect as much as the drying time occurs. In this case, carbon dioxide may be generated from the soda remaining in the molding to further form pores in the molding (step 4).
