Description
본 발명은 물유리 단열재의 제조방법에 관한 것으로서, 더욱 상세히는 불연재로서 인체에 무해하고 단열효과가 우수한 단열재를 물유리로 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a water glass heat insulating material, and more particularly to a method for producing a heat insulating material which is harmless to a human body and has excellent heat insulating effect as a non-combustible material.
일반적으로 단열재는 열의 이동을 차단하는 재료로서 건축물, 토목구조물, 전기제품, 차량 등에 단열 기능을 하도록 사용된다.In general, the heat insulating material is a material that blocks the movement of heat is used to heat insulation, such as buildings, civil structures, electrical appliances, vehicles.
이러한 단열재는 주로 시트 형상으로 성형되어 사용되는데, 폴리프로필렌, 폴리에틸렌. 폴리염화비닐, 게타포린, 타포린, 나일론, 스티로폼, 석면 등이 사용된다.Such insulation is mainly used in the form of sheets, polypropylene, polyethylene. Polyvinyl chloride, getaphorin, tarpaulin, nylon, styrofoam, asbestos and the like are used.
상기 단열재에서 석면을 제외한 재료들은 고열에서 용융시킨 상태에서 압연롤러를 통과하면서 시트 형상으로 성형한 후, 냉각시킨 것이다.The materials other than asbestos in the heat insulating material are cooled after being molded into a sheet shape while passing through a rolling roller in a molten state at a high temperature.
또한, 상기 석면은 화학접착제와 석면을 혼합한 상태에서 성형틀에 넣어서 압착하여 시트 형상으로 성형한 것이다.In addition, the asbestos is molded into a sheet shape by pressing in a molding mold in a state where the chemical adhesive and asbestos are mixed.
이러한 단열재는 건축물의 내벽 또는 외벽에 시공되거나 터널의 내측면에 부착되기도 하고, 냉장고와 같은 전자제품의 케이스 내측면에 부착되거나, 차량의 커버 내측면에 부착되어 외부의 열이 흡열되는 것을 차단하고, 내부의 열이 외부로 방열되는 것을 차단하는 기능을 하게 된다. Such insulation may be installed on the inner wall or outer wall of a building or attached to the inner side of a tunnel, attached to the inner side of a case of an electronic product such as a refrigerator, or attached to the inner side of a cover of a vehicle to prevent heat from being absorbed. In addition, the internal heat is prevented from radiating to the outside.
상기 배경기술에 의한 단열재는 다음과 같은 문제점이 있었다.The heat insulating material according to the background art had the following problems.
첫째, 인체에 유해하고 폐기 시, 환경을 오염시키는 문제점이 있었다. 즉, 상기 폴리프로필렌, 폴리에틸렌. 폴리염화비닐, 게타포린, 타포린, 나일론, 스티로폼은 모두 석유화학제품으로서 실내벽에 시공한 경우, 악취를 유발하면서 새집증후군을 발생시키면서, 호흡기질환 내지는 피부병을 발병시킨다. 또한, 폐기 시, 토양을 오염시키는 문제점이 있었다. 특히, 석면의 경우는 폐기 시, 석면 분진이 발생하면서 사람의 폐에 흡입된 후, 장기간 잔류하면서 폐암을 유발시키는 심각한 독성 물질이다.First, there is a problem that is harmful to the human body and pollutes the environment when disposed. That is, the polypropylene, polyethylene. Polyvinyl chloride, getaphorin, tarpaulin, nylon, and styrofoam are all petrochemicals, and when applied to the interior wall, they cause odor and develop sick house syndrome, causing respiratory diseases or skin diseases. In addition, when disposed, there was a problem of polluting the soil. In particular, asbestos is a seriously toxic substance that causes asbestos dust to be inhaled in the lungs of humans and remains for a long time, causing lung cancer.
둘째, 가연성의 물질이기 때문에, 연소 시, 유독가스를 발생시키는 문제점이 있었다. 상기 단열재 중 석면을 제외하고는 모두 가연성 물질로서, 착화가 용이하여 화재 발생의 주범이 되고 있는 실정이다. 특히, 화재 시, 다량의 유독가스가 발생하기 때문에 인명 사고에 치명적인 문제점이 있었다.Second, because it is a flammable material, there was a problem of generating toxic gases during combustion. Except for asbestos, all of the heat insulators are combustible materials, which are easily ignited and are the main culprit of fire. In particular, when a fire, a large amount of toxic gas is generated because there is a fatal problem in a human accident.
세째, 재료가 고가이므로 생산단가가 비싼 문제점이 있었다.Third, there is a problem that the production cost is expensive because the material is expensive.
네째, 제조 시, 부산물이 환경을 오염시키는 문제점이 있었다. 석면 이외의 재료는 모두 석유화학원료를 사용하기 때문에 부산물에는 다량의 환경오염물질들이 포함되어 있고, 상기 석면은 제조 시, 공기 중으로 분진으로 유출됨으로써 사람에게 흡입되는 심각한 문제점이 있었다.Fourth, when manufacturing, there was a problem that the by-products pollute the environment. Since all materials other than asbestos use petrochemical raw materials, a by-product includes a large amount of environmental pollutants, and asbestos has a serious problem of being inhaled by humans by being discharged into dust in the air during manufacture.

본 발명에 의한 물유리 단열재의 제조방법은, 발포되어 형성되기 때문에 내부에 다수의 기공이 형성되어 단열계수가 향상되고, 분쇄단계에서 형성된 입자가 구성되기 때문에, 강도 및 내마모성이 우수한 성질을 가지게 된다.Since the method for producing a water glass heat insulating material according to the present invention is formed by foaming, a plurality of pores are formed therein, the heat insulating coefficient is improved, and the particles formed in the crushing step are constituted, thereby having excellent strength and wear resistance.
또한, 인체에 무해한 물유리로 제조되기 때문에 시공하고 나서도 새집증후군처럼, 인체에 해를 끼치는 나쁜 현상이 발생하지 않으며, 제조 시에도 부산물로 물이 발생할 뿐, 다른 공해 물질이 발생하지 않으므로 환경을 보호할 수 있다. 그리고, 폐기 시에도 전혀 환경을 오염시키지 않을 뿐만 아니라, 내연성이 우수하기 때문에 화재 시에 유독가스를 전혀 발생시키지 않으므로 유독가스로 인한 인명사고를 예방할 수 있으며, 생산단가가 기존의 단열재에 비해 저렴하므로 경제적인 효과가 있다.In addition, since it is made of water glass, which is harmless to the human body, it does not cause bad phenomena to harm the human body like the sick house syndrome even after construction, and only water is generated as a by-product during manufacturing, and other pollutants do not occur to protect the environment. Can be. In addition, since it does not pollute the environment at all, and has excellent flame resistance, it does not generate any toxic gas at the time of fire, thus preventing human accidents due to toxic gas, and the production cost is lower than that of existing insulation materials. It has an economic effect.

상기 물유리 3호 300g에 알코올 100㎖를 넣어서 혼합하면, 알코올에 의해 물유리는 겔(gel) 상태로 변하면서 서서히 경화되기 시작하는데, 이때, 부산물로 물이 배출된다. 상기 물유리가 알코올에 의해 경화되는 것은, 일반적인 기술로서 결합수소로서 규산나트륨 중에 존재하는 
또한, 상기 알코올은 메틸알코올, 에틸알코올, 프로필알코올, 이소프로필알코올 중 어느 하나를 선택해서 사용하는데, 메틸알코올이 물유리와 반응성이 가장 높기 때문에 본 발명의 개질처리제로서 제일 적합하다. In addition, the alcohol is selected from any one of methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, and methyl alcohol is most suitable as the reforming agent of the present invention because methyl alcohol has the highest reactivity with water glass.
상기 알코올은 100㎖일 때, 물유리 3종 300g과 모두 반응할 수 있었다. 100㎖ 이상일 때에는 반응하지 않고 남는 알코올이 다량 발생하였으며, 그 이하일 때에는 반응하지 않는 물유리가 많이 발생 되었다. 따라서, 물유리 3종 300g과 알코올 100㎖의 배합이 가장 적합하였다.When the alcohol is 100ml, it was able to react with all 300g of three kinds of water glass. When 100 ml or more, a large amount of alcohol was left unreacted, and when it was less, a large amount of water glass which did not react was generated. Therefore, the combination of 300 g of three kinds of water glass and 100 ml of alcohol was the most suitable.
상기 발수단계에서는 상기 규산나트륨 중합체를 약 2시간∼3시간 동안 발수가 되도록 한다. 이 경우 함수율은 10∼15%인 겔 상태가 된다. 물론, 상기 혼합단계보다는 응고된 상태가 된다.In the water repellent step, the sodium silicate polymer is water repelled for about 2 hours to 3 hours. In this case, the moisture content is in a gel state of 10 to 15%. Of course, it becomes a solidified state rather than the mixing step.
일례로서 발수를 용이하게 하도록 규산나트륨 중합체를 스크린(screen)에 받쳐서 물이 신속히 발수되도록 하는 것이 바람직하다. As an example, it is desirable to support a sodium silicate polymer on a screen to facilitate water repellency so that water can be quickly repelled.
상기 발포단계에서는 상기 발수단계를 거친 겔 상태의 규산나트륨 중합체를 건조기에 넣어서 약 300℃에서 10분정도 가열시키면 함수된 물이 증발하면서 기포를 형성하게 되어 부피가 약 85% 팽창하면서 발포 현상이 일어난다. In the foaming step, when the sodium silicate polymer in the gelled state that has undergone the water repellent step is heated in a dryer for about 10 minutes at about 300 ° C., the water is evaporated to form bubbles as the volume of water expands to about 85%, causing a foaming phenomenon. .
이때, 가열수단으로서는 마이크로 웨이브(micro wave) 가열기가 적합한데, 그 이유는 고주파가 상기 규산나트륨 중합체의 내부 깊숙히 침투함으로써 고르게 발포시킬 수 있기 때문이다. 그러나, 일반적인 가열기를 사용할 경우에는 표면이 먼저 발포되면서 단열기능을 하게 되어, 원활한 발포가 어려울 수 있으므로, 본 발명에서는 상기 마이크로 웨이브 가열기를 사용하는 것이 바람직하다. 그러나, 상기 일반적인 가열기도 본 발명의 권리에 포함됨은 물론이다.At this time, a microwave heater is suitable as the heating means, because the high frequency allows the foam to be evenly foamed by penetrating deep into the inside of the sodium silicate polymer. However, in the case of using a general heater, since the surface is foamed first and thus performs a heat insulating function, smooth foaming may be difficult, so it is preferable to use the microwave heater in the present invention. However, the general heater is also included in the rights of the present invention.
상기 분쇄단계에서는 상기 발포된 규산나트륨 중합체를 분쇄하여 입자 형상이 되도록 하는데, 발포된 규산나트륨 중합체는 금세 경화되어 부서지기 쉬운 상태가 된다. 상기 입자의 크기는 모래알 정도가 바람직하다.In the pulverizing step, the foamed sodium silicate polymer is pulverized so as to have a particle shape, and the foamed sodium silicate polymer is cured quickly and becomes brittle. The particle size is preferably about the grain of sand.
상기 물유리 혼합단계에서는 상기 분쇄된 입자 형상의 규산나트륨 중합체에 물유리 3종을 300g 정도 넣어서 혼합하게 된다. 상기 물유리는 물유리 1호∼4호 중, 어느 하나를 선택해서 사용하는데, 3호 및 4호가 가장 적합하다. 만약, 물유리 1호 내지는 2호를 사용할 경우에는 물의 포함비가 물유리 3호 및 4호가 되도록 물을 더 추가하는 것이 바람직하다. In the water glass mixing step, about 300 g of water glass is mixed into the crushed granular sodium silicate polymer. Although the said water glass selects and uses any one of the water glass No. 1-4, No. 3 and 4 are the most suitable. If water glass 1 or 2 is used, it is preferable to further add water so that the water content ratio becomes water glass 3 and 4.
상기 알코올 혼합단계에서는 상기 물유리 혼합단계를 거친 혼합물에 알코올을 100㎖ 넣어서 혼합한다. 상기 알코올은 메틸알코올, 에틸알코올, 프로필알코올, 이소프로필알코올 중 어느 하나를 선택해서 사용하는데, 메틸알코올이 물유리와 반응성이 가장 높기 때문에 본 발명의 개질처리제로서 제일 적합하다. In the alcohol mixing step, 100 ml of alcohol is mixed into the mixture that has undergone the water glass mixing step. The alcohol is selected from any one of methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, and methyl alcohol is most suitable as the reforming agent of the present invention because methyl alcohol has the highest reactivity with water glass.
상기 건조단계에서는 20℃∼30℃의 상태에서 발수되면서 겔 상태로 응고시키는데 3시간∼5시간 정도 건조되도록 한다. 건조는 건조기를 통해서 실시할 수도 있고, 외부에서 햇빛을 통해서 건조시킬 수도 있다. 이렇게 건조단계를 거치면 물엿정도의 점도를 구비한 겔 상태가 된다.In the drying step it is to be dried for 3 hours to 5 hours to solidify in a gel state while water repellent in the state of 20 ℃ to 30 ℃. Drying may be carried out through a dryer, or may be dried by sunlight from the outside. After this drying step, a gel state with a viscosity of about starch syrup is obtained.
상기 성형단계에서는 건조단계를 거친 혼합물을 성형틀에 넣어서 마이크로 웨이브 건조기로 가열시킨다. 그러면, 발포하면서 성형틀 내부 구석구석에 꽉 차게 되어 성형틀의 형상이 고스란히 제조되도록 한다. 이때 온도는 250℃에서 5분 정도 로 한다. 그리고 이후에, 150℃에서 5분 정도 가열하여 수분이 완전히 증발되도록 한다. 상기 성형틀은 상형과 하형으로 구성되기 때문에 상형과 하형의 틈으로 상기 수분은 충분히 증발될 수 있다. 따라서, 상기 분쇄단계에서 형성된 입자를 응고된 물유리가 접착제 역할을 하면서 굳은 상태가 된다. 즉, 강정과 같은 상태가 된다. In the molding step, the mixture passed through the drying step is put into a mold and heated with a microwave dryer. Then, the foam is filled in every corner of the mold, so that the shape of the mold is produced intact. At this time, the temperature is set to about 5 minutes at 250 ℃. Then, after heating for 5 minutes at 150 ℃ to allow the water to evaporate completely. Since the mold is composed of an upper mold and a lower mold, the moisture can be sufficiently evaporated into the gap between the upper mold and the lower mold. Therefore, the water glass solidified in the particles formed in the grinding step serves as an adhesive and becomes a solid state. In other words, it is in the same state as Gangjeong.
상기 냉각단계에서는 상기 성형단계를 거친 뜨거운 단열재를 인출하여 자연상태에서 냉각되도록 하는데, 20℃∼25℃ 정도의 온도에서 1시간 정도 식히는 게 바람직하다.In the cooling step to take out the hot heat insulating material passed through the molding step to be cooled in a natural state, it is preferable to cool for about 1 hour at a temperature of about 20 ℃ to 25 ℃.
상기 제조방법에 의한 물유리 단열재는 분쇄단계에서 형성된 규산나트륨 입자가 규산나트륨 중합체와 혼합되어 강정처럼 응고되어 구성된다. 상기 규산나트륨 중합체는 물유리와 알코올이 섞여서 응고되는 혼합물을 일컫는데, 상기 제조방법에 서 사용하는 규산나트륨 중합체인 것을 특징으로 한다.In the water glass insulation material according to the above method, the sodium silicate particles formed in the crushing step are mixed with the sodium silicate polymer to solidify like a steel tablet. The sodium silicate polymer refers to a mixture in which water glass and alcohol are mixed and coagulated, characterized in that the sodium silicate polymer used in the production method.
상기 제조방법에 의해 만들어진 물유리 단열재는 성형단계에서 발포되기 때문에 내부에 다수의 기공이 형성되어 단열계수가 향상된다. 또한, 상기 분쇄단계에서 형성된 입자와 상기 입자의 접착제 역할을 하도록 건조단계에서 발포된 규산나트륨이 본래 단열계수가 높은 물질이므로 단열 기능을 더욱 보강하게 된다. 아울러, 상기 분쇄단계에서 형성된 입자가 구성되기 때문에 강도 및 내마모성이 우수한 성질을 가지게 된다. 또한, 인체에 무해한 물유리로 제조되기 때문에 시공하고 나서도 새집증후군처럼, 인체에 해를 끼치는 나쁜 현상이 발생하지 않는다. 제조 시에도 부산물로 물이 발생할 뿐, 다른 공해 물질이 발생하지 않으므로 환경을 보호할 수 있는 이점이 있다. 그리고, 폐기 시에도 전혀 환경을 오염시키지 않는 이점이 있다. 뿐만 아니라, 내연성이 우수하기 때문에 착화가 불가능하고, 화재 시, 유독가스가 전혀 발생하지 않으므로 유독가스로 인한 인명사고를 예방할 수 있으며, 저가이므로 생산단가가 적게 드는 이점이 있다.Since the water glass insulation made by the manufacturing method is foamed in the molding step, a plurality of pores are formed therein to improve the insulation coefficient. In addition, the sodium silicate foamed in the drying step to act as an adhesive of the particles and the particles formed in the crushing step is a material with a high thermal insulation coefficient is to further reinforce the thermal insulation function. In addition, since the particles formed in the grinding step are composed, it has excellent properties of strength and wear resistance. In addition, since it is made of water glass, which is harmless to the human body, even after construction, a bad phenomenon of harming the human body does not occur like the sick house syndrome. Water is produced as a by-product even during manufacture, and thus does not generate other pollutants, which has the advantage of protecting the environment. And, even when disposed, there is an advantage that does not pollute the environment at all. In addition, ignition is not possible because of excellent flame resistance, in the event of fire, toxic gas is not generated at all can prevent accidents due to toxic gas, there is an advantage that the production cost is low because it is low cost.
