Abstract
Description
본 발명은 우레탄폼이나 스티로폼을 재활용하여 불연 성능을 가지게 한 재활용 준불연 단열재와 관련된다.The present invention relates to a recycled semi-fireproof insulator having recycled urethane foam or styrofoam to provide fire-retardant performance.
일반적으로 건물의 벽체에는 단열패널을 설치하여 방음 및 단열이 이루어지게 하고 있다. 단열패널은 난연소재를 이용하여 만들거나 가연성소재의 패널에 난연액을 충진시켜 난연화할 수 있다.In general, the wall of the building is provided with a heat insulation panel to provide sound insulation and insulation. Adiabatic panels can be made of flame retardant materials or can be softened by filling flame retardant liquids in panels of flammable materials.
우레탄폼은 소재 자체가 단열성과 난연성을 가지고 있으므로 건축용 단열재로 제조되어 널리 사용되고 있다. 한편 스티로폼은 소재 자체는 가연성이나 난연액을 충진시켜 난연성 단열재로 널리 사용되고 있다.Urethane foam is widely used because it has heat insulation and flame retardancy. On the other hand, Styrofoam is widely used as a flame retardant insulation material because it is filled with flammable or flame retardant.
하지만 건물 철거시 벽체에서 나온 우레탄폼이나 스티로폼의 경우 폐기물로 취급되어 폐기되고 있고 이를 안전하게 폐기하기 위하여 막대한 처리비용이 발생하게 된다.However, when the building is demolished, urethane foam or styrofoam from the wall is disposed of as waste and disposal costs are incurred to safely dispose of it.
또한 우레탄폼은 소재 자체가 난연성을 가지기는 하지만 난연 기능이 비교적 낮아 화재시 불의 확산을 방지하는 기능이 상대적으로 떨어진다는 문제점이 있었다.In addition, although the urethane foam has a flame retardancy, the flame retardant function is relatively low, so that the function of preventing the spread of fire is relatively low.
본 발명은 우레탄폼이나 스티로폼을 재활용하여 불연 성능을 가지게 한 재활용 준불연 단열재를 제시한다.The present invention proposes a recyclable semi-fireproof insulator having recycled urethane foam or styrofoam to have fire-retardant performance.

이하, 본 발명의 일 실시예에 따른 재활용 준불연 단열재 및 재활용 준불연 단열재 제조방법에 대해 상세하게 설명한다.Hereinafter, a method for manufacturing recycled quasi-fireproof thermal insulation material and recycling quasi-fireproof thermal insulation material according to an embodiment of the present invention will be described in detail.
본 발명의 실시예에 따른 재활용 준불연 단열재는 폐기물로서 처리가 필요한 우레탄폼 또는 스티로폼을 분쇄하여 형성되는 분쇄폼자재 및 이 분쇄폼자재들을 상호 결합시키고 불연 성능을 가지고 있는 바인더를 포함한다.The recycled quasi-fireproofing material according to an embodiment of the present invention includes a crushed foam material formed by crushing urethane foam or styrofoam which needs to be treated as waste, and a binder that binds the crushed foam materials together and has a fireproof performance.
우레탄폼은 유기물질이며 우레탄폼이 난연성을 가진다고 하더라도 일정한 열이 가해지면 유독가스인 시안가스나 유해한 시안화합물이 발생하므로 완전한 불연이 되기는 어렵다. 따라서 여기에서 준불연이란 유기물질 중에서는 불연에 준한다는 의미로서 일반적인 용어로는 난연2급과 유사한 의미이다.Urethane foam is an organic substance and even if urethane foam has flame retardancy, it is difficult to be completely incombustible because a toxic gas such as cyanogen gas or harmful cyanide compound is generated when constant heat is applied. Therefore, the term "semi-fire" means that the organic material is based on fire-retardant.
본 발명의 실시예에 따른 준불연 단열재는 우레탄폼 또는 스티로폼의 분쇄된 폐자재와 바인더를 포함한다. 폐자재는 우레탄폼이나 스티로폼을 파쇄한 것을 사용할 수 있다. 이와 같이 기본 소재로 폐자재를 사용함으로써 처리 비용을 절감하고 환경 보호에 이바지할 수 있다.A quasi-fireproof insulation according to an embodiment of the present invention includes a wasted waste material of urethane foam or styrofoam and a binder. Waste materials can be obtained by shattering urethane foam or styrofoam. By using the waste material as the basic material in this way, it is possible to reduce the processing cost and contribute to environmental protection.
한편 바인더는 무기바인더와 유기바인더 및 발포제가 혼합되어 형성된다.Meanwhile, the binder is formed by mixing an inorganic binder, an organic binder and a foaming agent.
무기바인더는 시멘트, 석고, 인산암모늄, 규산소다, 황산알루미늄, 산화마그네슘, 생석회, 규산칼륨, 황토를 포함하는 성분이 혼합되어 이루어진다.The inorganic binder is composed of a mixture of cement, gypsum, ammonium phosphate, sodium silicate, aluminum sulfate, magnesium oxide, quicklime, potassium silicate and loess.
시멘트는 일반적으로 토목용이나 건축용의 무기질의 결합 경화제를 말하고, 석고는 구워서 소석고로 하여 주물의 모형 제작 재료나 의료용 깁스 등에 사용되거나 비료나 백색의 안료로 쓰이며 시멘트의 혼합 재료로 사용할 수 있다. 한편 황토는 규토와 흙으로 이루어진 자연 상태의 흙이며 크기가 미세한 입자로 이루어진다. 황토는 색깔을 내는 안료의 용도를 겸할 수 있다. 이와 같은 무기바인더 성분에 의해 기본적인 불연성을 확보할 수 있다.Cement is generally used as binding curing agent for minerals in civil engineering and construction, and gypsum can be used as a calcining material for casting molds, medical casts, medical pellets, fertilizer or white pigment and used as a mixture of cement. On the other hand, loess is a natural soil composed of silica and soil, and it is composed of fine particles. Horticulture can also serve as a coloring pigment. Basic inorganic matter can be ensured by such an inorganic binder component.
인산암모늄은 방염제로 기능하며 탈수작용에 의해 탄화물 형성을 용이하게 하여 화재가 진행되는 것을 억제한다.Ammonium phosphate functions as a flame retardant and facilitates the formation of carbides by dehydration, thereby inhibiting the progress of the fire.
규산소다는 물에 잘 녹으며 시멘트의 급결제나 접착제로 사용할 수 있다. 황산알루미늄은 물의 정화시 응집제로 많이 사용되는 것으로 무기바인더의 접착성을 높여준다. 한편 산화마그네슘은 내화성을 가지고 있으며 무기바인더의 접착 작용을 촉진한다. Sodium silicate dissolves well in water and can be used as a curing agent or adhesive for cement. Aluminum sulfate is widely used as a flocculant in the purification of water, which enhances the adhesion of inorganic binders. Magnesium oxide, on the other hand, is fire resistant and promotes the adhesion of inorganic binders.
한편 생석회는 석회석의 열분해로 이산화탄소가 배출되어 만들어지고 수분과 반응하여 발열 팽창한다. 이 때 밀도가 높아지게 되어 강도를 증가시킨다. 규산칼륨은 다른 성분과의 높은 용해도와 접착성을 보이고, 투명하고 내화도 및 내열성이 우수하며 접착 작용을 함과 동시에 무기바인더의 경화 후 강도를 높여준다.On the other hand, quicklime is produced by discharging carbon dioxide by pyrolysis of limestone, reacts with moisture, and exothermally expands. At this time, the density is increased and the strength is increased. The potassium silicate exhibits high solubility and adhesion with other components, is transparent, has excellent fire resistance and heat resistance, exhibits an adhesive action, and increases the strength of the inorganic binder after curing.
이들의 함량은, 시멘트와 석고의 혼합물 1~30중량%, 인산암모늄 1~30중량%, 산화마그네슘과 규산소다와 황산알루미늄의 혼합물 1~30중량%, 생석회와 규산칼륨의 혼합물 1~30중량%, 황토 1~20중량%로 하는 것이 바람직하다.The content thereof is 1 to 30% by weight of a mixture of cement and gypsum, 1 to 30% by weight of ammonium phosphate, 1 to 30% by weight of a mixture of magnesium oxide and sodium silicate and aluminum sulfate, 1 to 30% by weight of a mixture of calcium oxide and potassium silicate By weight, and 1 to 20% by weight of loess.
이와 같이 구성하는 경우 난연 기능과 방염 기능을 적절히 가지면서 접착 및 경화가 잘 되고 경화된 후의 강도도 우수하다.In the case of such a constitution, the flame-retarding function and the flame-retarding function are appropriately carried out, and adhesion and curing are good and the strength after curing is excellent.
유기바인더는 PVA(폴리비닐알코올), 페놀수지, 요소수지, 멜라민수지를 포함하는 성분이 혼합되어 이루어진다.The organic binder is made by mixing components including PVA (polyvinyl alcohol), phenol resin, urea resin, and melamine resin.
유기바인더는 제조가 간단하여 널리 사용되지만 기본적으로 불에 탈 수 있는 성질을 가진다. 위에 열거한 성분들은 유기바인더 중에서도 난연 기능과 방염 기능이 우수한 것으로서 경제성을 좋게 하면서도 불연 성능을 가지게 하기 위하여 채택할 수 있다.Although organic binders are widely used because they are simple to manufacture, they are basically fireproof. Among the organic binders listed above, the organic binder is excellent in flame retarding function and flame retarding function, and can be adopted in order to improve the economical efficiency and to have the fire retardant performance.
발포제는 열에 의해 팽창되어 발포됨으로써 무기바인더와 유기바인더가 분쇄폼자재에 부착되기 용이하게 하고 무기바인더와 유기바인더에 기공이 형성되도록 한다.The foaming agent is expanded by heat and foamed to facilitate attachment of the inorganic binder and the organic binder to the crushed foam material, and pores are formed in the inorganic binder and the organic binder.
여기에서 발포제는, 탄산수소칼슘(중탄산칼슘), 팽창흑연이 혼합된 성분으로 이루어질 수 있다. 탄산수소칼슘은 발포되면서 바인더가 분쇄폼자재에 골고루 퍼지도록 하며 팽창흑연은 발포되면서 분쇄폼자재의 표면을 코팅하는 형태가 되어 불연 기능을 강화시킨다.Here, the blowing agent may be composed of a mixture of calcium hydrogen carbonate (calcium bicarbonate) and expanded graphite. Calcium bicarbonate is foamed so that the binder spreads evenly over the crushed foam material, while the expanded graphite is foamed to coat the surface of the crushed foam material, enhancing the non-burning function.
이와 같은 조성의 바인더는 점착력과 접착력이 우수한 불연 바인더이다. 특히 페기물로 나오는 우레탄폼이나 스티로폼 등을 일정한 크기로 파쇄(분쇄)한 소수성인 페폼에 잘 혼합되어 코팅이 되고, 상온 또는 열경화나 마이크로웨이브로 건조시키면 쉽게 경화되어 고착화가 되는 장점을 가진다.
The binder having such a composition is a fire-retardant binder excellent in adhesion and adhesion. Particularly, it has a merit that it is mixed with a hydrophobic pome which is crushed (pulverized) into urethane foam or styrofoam which is produced as waste and is uniformly coated, and hardened easily when it is dried at room temperature or thermosetting or microwave.
다음은 본 발명의 실시예에 따른 재활용 준불연 단열재의 제조방법에 대하여 도면을 참조하여 상세하게 설명한다.Hereinafter, a method of manufacturing recycled semi-inflammable thermal insulation material according to an embodiment of the present invention will be described in detail with reference to the drawings.
도 1은 본 발명의 실시예에 따른 재활용 준불연 단열재의 제조방법을 나타내는 순서도이다.1 is a flowchart showing a method of manufacturing recycled semi-inflammable insulation material according to an embodiment of the present invention.
먼저 분쇄된 폐우레탄폼 또는 폐스티로폼과 바인더를 혼합한다(S10). 바인더는 상술한 성분으로 이루어진 것으로 별도의 설명을 생략한다. 바인더는 폐우레탄폼 또는 폐스티로폼을 상호 결합시키고 불연 성능을 가지게 한다.First, pulverized waste urethane foam or waste styrofoam is mixed with a binder (S10). The binder is made of the above-mentioned components, and a separate explanation will be omitted. The binder binds the waste urethane foam or waste styrofoam together and has a fire retardant performance.
여기에서 바인더와 폐우레탄폼 또는 폐스티로폼의 혼합 비율은 바인더 100중량부를 기준으로 폐우레탄폼 또는 폐스티로폼은 20 내지 40중량부를 혼합시키는 것이 바람직하다.The mixing ratio of the binder to the waste urethane foam or the waste styrofoam is preferably 20 to 40 parts by weight based on 100 parts by weight of the binder, or 20 to 40 parts by weight of waste urethane foam or waste styrofoam.
또는 폐우레탄폼폐스티로폼을 분쇄하여 사용하는 경우 분쇄물의 크기와 모양이 균일하지 않고 비중도 불규칙적일 수 있으므로 배합비의 차이가 있을 수 있다. 실험적으로 폐우레탄폼 분쇄물의 크기가 5mm ~ 7mm정도인 경우 바인더는 폐우레탄폼 또는 폐스티로폼의 중량 대비 4배 정도를 혼합하는 것이 적합하다.Or pulverized urethane foamed styrofoam is used, the size and shape of the pulverized product may not be uniform and the specific gravity may be irregular. Experimentally, when the size of pulverized waste urethane foam is about 5 mm to 7 mm, it is preferable to mix about 4 times as much as the weight of waste urethane foam or waste styrofoam.
다음으로 혼합단계를 마친 소재를 일정한 금형 또는 주형에 넣고 압착한다(S20). 이 과정에서 폐우레탄폼 또는 폐스티로폼들은 서로 밀착된다. 또한 바인더의 탄산수소칼슘과 팽창흑연이 팽창하면서 폐우레탄폼 또는 폐스티로폼 조각들의 표면으로 바인더가 골고루 퍼지면서 기공이 형성되는 한편 폐우레탄폼 또는 폐스티로폼의 표면을 덮어 표면이 외부에 노출되지 않게 된다.Next, the material having been subjected to the mixing step is put into a certain mold or mold and pressed (S20). In this process, the waste urethane foam or the waste styrofoam are in close contact with each other. In addition, calcium carbonate and expanded graphite of the binder are expanded to form pores by uniformly spreading the binder on the surfaces of the waste urethane foam or the waste foamed styrofoam, and the surface of the waste urethane foam or the waste styrofoam is covered so that the surface is not exposed to the outside .
다음으로 압착단계를 마친 소재를 금형 또는 주형으로부터 분리한다(S30).Next, the material having undergone the compression step is separated from the mold or the mold (S30).
한편 이와는 별도로 압착단계가 종료된 후 바인더를 일정한 시간을 두고 금형 또는 주형에 더 투입하고 탈형한 후 탈수하는 단계를 거칠 수 있다. 예를 들어 압착이 끝난 후 일정량의 바인더를 금형 또는 주형에 투입하면 투입된 바인더가 이미 코팅을 마친 바인더들을 서로 융합시키면서 응고시키는 작용을 한다. 또한 이러한 과정을 거친 소재를 금형 또는 주형으로부터 분리한 후 탈수하는 단계를 거침으로써 불연성을 향상시키면서 제품의 품질을 깨끗하고 안정적으로 할 수 있다.Separately, after the compression step is completed, the binder may be further injected into the mold or the mold for a certain period of time, demolded, and dehydrated. For example, when a certain amount of binder is put into a mold or a mold after the pressing, the injected binder functions to coalesce the already coated binders with each other. Also, by separating the material that has undergone this process from the mold or the mold and dehydrating it, the quality of the product can be made clean and stable while improving the incombustibility.
다음으로 탈형단계를 마친 소재를 건조시킨다(S40). 상온에서 건조하는 경우 24시간 정도의 건조시간이 필요하고, 열풍건조는 80도에서 20분 정도 걸리며, 마이크로웨이브로 건조하는 경우 열풍건조보다 2배에서 10배 정도 빨리 건조된다.Next, the material having been subjected to the demolding step is dried (S40). Drying at room temperature requires about 24 hours of drying time. Hot-air drying takes about 20 to 20 minutes. When microwave drying is used, it is dried about 2 to 10 times faster than hot-air drying.
다음으로 건조단계를 마친 소재를 일정한 크기로 재단한다(S50). 이에 따라 일정 크기를 가진 재활용 준불연 단열재를 얻을 수 있다.Next, the dried material is cut to a predetermined size (S50). As a result, a recycled quasi fireproof insulation material having a predetermined size can be obtained.
이와 같이 제조된 준불연 단열재는 불연성 무기물을 포함하고 바인더의 팽창과 발포 및 코팅과 접착에 의해 화염이 우레탄폼이나 스티로폼에 접근하는 것을 방지하는 한편 바인더에 기공이 형성되어 가볍고 단열 성능이 우수하다.The semi-fireproof insulator thus manufactured contains a non-combustible inorganic material and prevents the flame from approaching the urethane foam or the styrofoam by the expansion, foaming, coating and adhesion of the binder, and the pore is formed in the binder.
구체적으로는 무기물질이 코팅 접착 발포되므로 불에 강한 준불연성이다. 단열성에 있어서도 기존 우레탄 및 스티로폼의 단열성을 거의 동일하게 유지할 수 있고 바인더에 형성되는 기공으로 인하여 흡음 및 방음력이 우수하다.Specifically, since the inorganic substance is coated and adhered to foam, it is semi-flammable which is strong to fire. The heat insulating property of the existing urethane and styrofoam can be kept almost the same, and the sound absorption and the deodorizing force are excellent due to the pores formed in the binder.
또한 원료 소재 자체가 폐기물을 이용하므로 원재료비가 적게 들고 바인더의 자체 제조 및 대량 생산이 가능하므로 생산원가가 적게 들어간다. 폐기물인 우레탄폼이나 스티로폼을 재활용하므로 국가의 환경오염방지 및 환경보존에 기여를 함과 더불어 국가의 이익과 페기물 발생하는 기업에 많은 기여를 할 수 있다.In addition, since the raw material itself uses waste, the raw material cost is low, and the binder can be manufactured by itself and mass-produced, so that the production cost is reduced. Urethane foam or styrofoam, which is waste, can be recycled, contributing to the prevention of environmental pollution and preservation of the environment of the country, as well as contributing to the interests of the national government and waste generation enterprises.
또한 공정상에 발포 팽창 공정이 있고 이에 더하여 폐우레탄폼이나 폐스티로폼이 이미 발포되어 있으므로 가볍고 견고하며 완충력이 우수하다. In addition, there is a foaming and expansion process in the process. In addition, since the waste urethane foam and the waste styrofoam are already foamed, they are light and firm and have excellent buffering power.
또한 무기물질이 안정적으로 융합이 되므로 경화가 된 후에는 견고하고, 내수성이 좋다. 경화된 재생폼은 내수성을 가지므로 물이 침투하지 못하고 기공을 통해 흐르게 되며 이에 따라 중력에 의해 상부의 물이 아래로 배출될 수 있다.In addition, since inorganic materials are stably fused, they are firm and water-resistant after curing. The cured regenerated foam has water resistance, so that the water can not penetrate and flow through the pores, and therefore the water at the top can be discharged downward by gravity.
또한 바인더에 안료 또는 염료를 넣어 색상도 여러 가지로 낼 수 있으며 금형 또는 형틀의 모양에 따라 여러 가지 모양으로 성형할 수 있다.
In addition, pigments or dyes can be added to the binder to give a variety of colors, and various shapes can be formed depending on the shape of the mold or the mold.
다음으로 본 발명의 일 실시예에 따른 준불연 단열재에 대하여 상세하게 설명한다. 하기 실시예는 본 발명의 한 형태를 예시하는 것에 불과할 뿐이며, 본 발명의 범위가 하기 실시예에 의해 제한되는 것은 아니다.Next, a semi-fireproof insulator according to an embodiment of the present invention will be described in detail. The following examples are merely illustrative of one aspect of the present invention, and the scope of the present invention is not limited by the following examples.
[실시예 1][Example 1]

Then, 80 parts by weight of the binder was put into the mold, , 80 parts by weight of the above binder was put into a mold, the molded product was demoulded, dehydrated by a dehydrator, and then dried in a microwave for 5 minutes to prepare a recycled quasi-fire insulating material.
실시예 1 내지 실시예 3에 따라 제조된 준불연 단열재에 대하여 연소실험을 하였고, 비교예 1 내지 비교예 2에 대해서도 동일한 연소실험을 하여 그 결과를 비교하였다.Combustion experiments were carried out on the semi-inflammable insulation materials prepared according to Examples 1 to 3, and the same combustion experiments were conducted on Comparative Examples 1 to 2, and the results were compared.
비교예 1과 비교예 2는 국내에서 널리 사용되고 있는 영보화학과 세이크사의 우레탄 단열재이다. 비교예 1이 영보화학의 우레탄 단열재이고 비교예 2가 세이크사의 우레탄 단열재이다.Comparative Example 1 and Comparative Example 2 are Urethane insulating materials of Seiko Co., Ltd., which are widely used in Korea. Comparative Example 1 is Urethane insulation material of Young Chemical and Comparative Example 2 is Urethane insulation material of Sheikh Company.
연소실험에서 버너는 1000도 이상 온도를 올릴 수 있는 부탄가스 토치램프를 사용하였고 불꽃의 길이는 10센티미터로 하였으며 실험시간은 1분으로 하였다. 이와 같이 실험한 결과를 아래의 표 1에 나타낸다.In the combustion test, a butane gas torch lamp capable of raising the temperature of 1000 ° C or higher was used as the burner, the length of the flame was 10 cm, and the test time was 1 minute. The results of the experiment are shown in Table 1 below.
표에서 알 수 있는 바와 같이 본 발명의 실시예에 따른 준불연 단열재는 1분의 연소실험 후 잔염이 없을 정도로 불번짐이 없고 탄화길이도 적었으며 발생 연기 양도 적어 불연재로서 뛰어난 성능을 가짐을 확인할 수 있었다.As can be seen from the table, the quasi-fireproof insulation according to the embodiment of the present invention has no flammability, less carbonization length, and small amount of smoke after combustion test for 1 minute, there was.
한편 비교예 1의 경우 1분의 연소실험이 종료된 후에도 323초 동안 불이 남아 있는 상태였고 탄화길이도 다소 큰 편이다. 비교예 2의 경우는 비교예 1의 경우보다도 불연 성능이 조금 더 떨어짐을 알 수 있다.On the other hand, in the case of Comparative Example 1, the fire was still present for 323 seconds after the completion of the one-minute combustion test, and the carbonization length was somewhat large. It can be seen that the flame retardancy is slightly lower in the case of the comparative example 2 than in the case of the comparative example 1.
이에 따라 본 발명의 실시에에 따른 준불연 단열재의 불연 성능이 기존의 제품보다 뛰어남을 알 수 있다.Accordingly, it can be seen that the anti-fire performance of the semi-fireproof insulator according to the embodiment of the present invention is superior to the existing product.
