우레탄폴 콘크리트의 시공방법{Construction method of concrete having wasted rigid polyurethane foam}Construction method of concrete having wasted rigid polyurethane foam

본 발명은 우레탄폴 기포 콘크리트의 시공방법에 관한 것으로, 더욱 상세하게는 가전제품의 단열재 등으로 사용된후 폐기처분되는 우레탄폼을 재활용하여 이를 아파트나 주택의 온돌 바닥재 시공시 콘크리트에 혼합하여 시공함으로써, 시공부위의 경량화와 뛰어난 차음효와 단열효과를 얻고, 균열을 방지할 수 있으며, 시공이 간편하고 경제성이 있는 우레탄폴 콘크리트의 시공방법에 관한 것이다.The present invention relates to a construction method of urethane pole foam concrete, and more specifically, by recycling the urethane foam that is discarded after being used as a heat insulator of home appliances, by mixing it with concrete when constructing an on-floor floor of an apartment or house It is about the construction method of urethane pole concrete which can get light weight and excellent sound insulation effect and insulation effect, can prevent the crack, and is easy and economical to construct.

많은 외화를 들여 수입한 원료를 이용하여 만드는 폴리우레탄 폼은 국내에서의 생산량이 대략 그 원료의 사용량을 기준으로 볼 때 연간 45만∼50만톤 가량 될 것으로 추정되며, 이렇게 생산된 폴리우레탄 폼은 냉장고와 같은 가전제품에서 단열재 등으로 특성에 맞게 여러 용도로 사용되고 있으나, 사용후 처리문제로 상당히 어려움을 겪고 있으며 주로 매립이나 소각에 의존하고 있는 실정이다.Polyurethane foam made from raw materials imported from many foreign currencies is estimated to be about 450,000 to 500,000 tons per year based on the amount of raw materials used in domestic production. Although it is used for various purposes according to its characteristics as a heat insulator in home appliances, such as home appliances, it suffers considerably from post-treatment problems, and mainly depends on landfill or incineration.

일반적으로 폴리우레탄은 열경화성 수지로서 열에 녹지 않아 재활용이 곤란하며, 태울때는 분자 내의 질소와 방향족 고리가 잔류하게 되고, 단열재로 사용된 발포 폴리우레탄의 경우 발포제로 사용된 프레온(CFC)이 폼 내부에 남아있게 된다. 우레탄이 포함하고 있는 자체 질소는 이산화질소를 발생시켜서 환경오염 물질을 발생시키기 때문에 소각에 의한 처리에도 많은 문제점이 있다. 또한, 발포 폴리우레탄의 경우는 밀도가 매우 낮아서 매립에도 어려움이 있으며, 난분해성 물질이므로 매립 또한 함부로 할 수 없는 문제점이 있다.In general, polyurethane is a thermosetting resin, so it is difficult to recycle because it does not dissolve in heat, and when burned, nitrogen and aromatic rings in the molecule remain, and in the case of the foamed polyurethane used as a heat insulating material, Freon (CFC) used as a foaming agent is used in the foam. Will remain. Since the nitrogen contained in the urethane generates nitrogen dioxide, which causes environmental pollutants, there are many problems in the treatment by incineration. In addition, in the case of foamed polyurethane, the density is very low, so there is a difficulty in embedding, there is a problem that can not be buried because it is a hardly decomposable material.

따라서, 폐 폴리우레탄을 효과적으로 재활용할 수 있는 기술의 개발 필요성이 대두되고 있다.Therefore, there is a need to develop a technology that can effectively recycle waste polyurethane.

이하, 첨부된 도면을 참조하여 본 발명에 따른 우레탄폴 콘크리트의 시공방법에 대하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the construction method of the urethane pole concrete according to the present invention.

현재 아파트나 주택에서 시공하고 있는 방바닥 단열재로는 폴콘크리트, 기포콘크리트, 기포 폴콘크리트, 화이바믹스 기포콘크리트, 에바(EVA) 폴 기포콘크리트, BST 폴 기포콘크리트, 우레셸 기포콘크리트 등을 들 수 있다. 이중에서 시공상의 간편성 때문에 기포콘크리트를 많이 사용하여 왔는데, 단열층에서 많은 균열이 발생하는 문제점이 있었다. 이를 해결하기 위해서 기포콘크리트에 많은 첨가제를 넣어 시공하였지만, 균열을 효과적으로 제거할 수 없었다.The floor insulation currently being constructed in apartments and houses includes Pole Concrete, Bubble Concrete, Bubble Pole Concrete, Fiber Foam Concrete, EVA Pole Foam Concrete, BST Pole Foam Concrete, and Ureshell Foam Concrete. Among them, foam concrete has been used a lot because of its simplicity in construction, and there is a problem that many cracks occur in the insulation layer. In order to solve this problem, many additives were added to aerated concrete, but cracks could not be effectively removed.

따라서, 최근에는 기포콘크리트보다 폴콘크리트를 선호하게 되었지만, 단열 전문업체의 현장관리 미숙과 제품관리 부족으로 인하여 폴콘크리트 시공도 현장에서 많이 외면을 당하는 처지에 놓여 있다.Therefore, in recent years, it has been preferred to concrete concrete than foam concrete, but the construction of pole concrete is also faced with a lot of external conditions due to the insufficiency of on-site management and lack of product management.

본 발명에서는 이러한 문제점을 일거에 해결하여 제품성이나 시공성에서 거의 완벽에 가까운 방바닥/벽체 단열 경량콘크리트를 제조하고자 하였다.In the present invention to solve these problems at a glance, it was intended to manufacture a light weight concrete for the floor / wall insulation almost close to the perfect product or construction.

이를 위해서, 본 발명에서는 폐 가전제품, 특히 폐 냉장고에서 배출되는 폐 우레탄폼을 재활용하여 건축자재로의 이용을 도모하였으며, 그러한 방안으로서 건축자재로 사용하였을 때 경량화, 뛰어난 차음효과와 단열성, 시공성 등 여러 가지 장점을 제공할 수 잇는 단열 콘크리트의 개발이 적절할 것으로 판단하였다. 따라서, 폐 우레탄폼을 재활용하여 경량의 단열 우레탄폴 콘크리트를 만들어서 아파트 등의 공동주택 방바닥에 바닥재로서 사용하고자 한 것이다.To this end, in the present invention, waste urethane products, in particular waste urethane foam discharged from the waste refrigerator is recycled to promote the use of building materials, such a method when used as building materials, light weight, excellent sound insulation effect and insulation, construction properties, etc. It was judged that the development of insulating concrete could provide various advantages. Therefore, the waste urethane foam is recycled to make a lightweight insulating urethane pole concrete to be used as flooring in the floors of apartment houses such as apartments.

실시예Example

본 발명에 따르면, 먼저 폐 가전제품에서 발생하는 폐 우레탄폼을 수거하여 특수제작된 분쇄기로 약 2∼8mm의 크기로 분쇄를 하고, 마찬가지로 폐 폴리스틸렌(스치로폴)을 수거하여 분쇄기로 약 2∼8mm의 크기로 분쇄한다. 이렇게 분쇄된 우레판폼과 스치로폴을 7 : 3의 중량비로 혼합하여 스퀴즈 우레탄폴(S.U.P)을 만든다.According to the present invention, first, waste urethane foam generated from waste household appliances is collected and ground to a size of about 2 to 8 mm by a specially manufactured grinder, and waste polystyrene (Schiropol) is collected and similarly about 2 to 8 mm by a grinder. Crush to size. The crushed urethane foam and Schiropol are mixed at a weight ratio of 7: 3 to form a squeeze urethane pole (S.U.P).

다음에는, 스퀴즈 우레탄폴에 본 발명에 따라 특수 개발된 혼화제(P.P.S)를 첨가한후 시멘트, 모래, 물을 적정한 비율로 혼합한다. 이때, 스퀴즈 우레탄폴은 용적비로 약 75%에 해당하는 양만큼 혼합하며, 혼화제(P.P.S)는 약 1%, 시멘트는 약 22%, 그리고 모래는 약 2%에 해당하는 양만큼 혼합한다.Next, a specially developed admixture (P.P.S) according to the present invention is added to the squeeze urethane pole, and then cement, sand and water are mixed at an appropriate ratio. At this time, the squeeze urethane pole is mixed in an amount of about 75% by volume, admixture (P.P.S) is about 1%, cement is about 22%, and sand is mixed by about 2%.

상기 혼화제(P.P.S)는 재료분리방지 및 유동화제의 기능을 갖는 것으로, 주성분이 수용성 셀룰로즈에텔 계열인 육회색 분말이다. 시멘트로는 KSL 5201에 합격한 제품으로 제조후 2개월 이내의 신선한 재료로서 KSF 2526에 적합한 것을 선정하여 사용한다. 콘크리트용 모래로는 KSF 2526에 합격하고 조립율이 2∼3 정도의 적당한 입도를 갖는 재료를 사용한다. 혼합용수는 콘크리트용으로 유해하지 않은 것을 사용한다.The admixture (P.P.S) has a function of preventing material separation and fluidizing agent, and is a grey-gray powder whose main component is a water-soluble cellulose ether series. As cement, KSL 5201 has passed and it is a fresh material within 2 months after manufacture. As the sand for concrete, a material having passed the KSF 2526 and having an appropriate granularity of about 2-3 is used. Use mixed water that is not harmful for concrete.

상기 재료들의 혼합은 공사현장 지상에서 콘크리트 믹서를 이용하여 수행하고, 이렇게 혼합된 경량 단열 우레탄폴 콘크리트는 특수 개발된 스퀴즈 펌프를 이용하여 재료분리 현상이 일어나지 않도록 혼합장소로부터 각각의 타설 장소에 압송한다. 이때, 본 발명에 따라 특수 개발된 스퀴즈 펌프는 시공현장 바닥에서 배합한 콘크리트를 최고 30층 높이까지 압송할 수 있다.The mixing of the materials is carried out using a concrete mixer on the ground of the construction site, and the mixed lightweight insulating urethane pole concrete is pumped from the mixing place to each place to prevent material separation by using a specially developed squeeze pump. . At this time, the specially developed squeeze pump according to the present invention can pump the concrete compounded at the floor of the construction site up to the height of 30 floors.

스퀴즈 펌프에 의해서 압송한 재료가 시공부위에 올라오면 장비를 이용하여 고르게 펴고 봉 등으로 구석진 곳 다짐을 한다. 경량 단열 우레탄폴 콘크리트의 운반 또는 타설도중 심한 재료 분리현상이 있으면, 거듭 비비기를 하여 균등질로 만든다. 또한, 콘크리트에 잡물이 혼입되는 것을 방지하고, 흡수우려가 있는 곳은물로 적셔준다. 2단 이상으로 작업을 할 경우에는 아래단 콘크리트가 굳기전에 윗단 콘크리트를 타설하여 일체가 되도록 한다.When the material pushed by the squeeze pump comes up to the construction site, use the equipment to spread it evenly and compact it with a stick. If there is severe material separation during transportation or placing of lightweight insulating urethane pole concrete, it is made to be homogeneous by rubbing repeatedly. In addition, to prevent the mixing of miscellaneous goods into the concrete, the place where there is concern of absorption is moistened with water. When working in two or more stages, cast the upper concrete before solidifying the lower concrete so that it is integrated.

타설후에는 급격한 온도변화가 없도록 양생해야하며, 경화중에 진동, 충격, 과중한 하중이 가해지지 않도록 유의한다. 양생기간은 하절기(30℃ 이하)엔 최저 3일, 동절기(1℃ 이상)엔 4∼5일 이상 양생한다.After pouring, it should be cured so that there is no sudden temperature change, and care should be taken not to apply vibration, shock or heavy load during curing. Curing period is at least 3 days in summer (below 30 ℃) and 4-5 days in winter (more than 1 ℃).

상기 표 1을 참조하면, 본 발명에 따른 스퀴즈 우레탄폴 콘크리트는, 일반 시멘트 콘크리트의 비중이 2.3∼2.4인데 비하여 그 비중이 0.5∼1.4로서, 콘크리트의 하중을 1/2∼1/3 이하로 경량화시켜 공사비를 절감할 수 있게한다. 또한, 콘크리트의 배합에 따라 강도를 5∼250kgf/cm2로 자유롭게 변화시킬 수 있고, 열전도율이 일반 콘크리트(1.4kcal/m2h℃)의 1/2∼1/3(0.1∼0.8kcal/m2h℃)로서 단열효과가크다. 게다가, 몰탈과의 접착력이 크고, 균일한 배합으로 인하여 균열 및 들뜸현상을 방지한다.Referring to Table 1, the squeeze urethane pole concrete according to the present invention has a specific gravity of 0.5 to 1.4 as compared to 2.3 to 2.4 of general cement concrete, and reduces the load of the concrete to 1/2 to 1/3 or less. To reduce construction costs. In addition, the strength can be freely changed to 5 to 250 kgf / cm 2 depending on the mixing of concrete, and the thermal conductivity is 1/2 to 1/3 (0.1 to 0.8 kcal / m) of general concrete (1.4 kcal / m 2 h ° C). 2 h ° C.), the adiabatic effect is large. In addition, the adhesion to mortar is large, and uniform mixing prevents cracking and lifting.

또한, 본 발명에 따른 스퀴즈 우레탄폴 콘크리트는 방습성이 타콘크리트보다 매우 낮아서 결로나 곰팡이나 세균류의 영향을 받지 않으며, 내부 충격에 의한 차음성이 기존 경량 단열 콘크리트 중에서 가장 양호하다. 게다가, 수축작용이 없고 신축에 의한 균열발생이 일어나지 않으며, 경화시간이 짧으므로(3∼4일) 공기단축이 가능하고 타후속 공정으로 진행을 쉽게한다. 또한, 동결 용해 내구성지수가 타콘크리트에 비하여 월등하게 좋아서 결로 및 동파의 우려가 없고, 충격 에너지 흡수가 대단히 크므로 진동에너지 흡수에 의한 방진성이 대단히 좋다.In addition, the squeeze urethane pole concrete according to the present invention is very low moisture-proof than other concrete is not affected by condensation or mold or bacteria, and sound insulation due to internal impact is the best among existing lightweight insulating concrete. In addition, there is no shrinkage action, no cracking occurs due to expansion and contraction, and the curing time is short (3 to 4 days), which shortens the air and makes it easier to proceed to other subsequent processes. In addition, the freeze-melting durability index is much better than other concrete, there is no fear of condensation and freezing, and the shock energy absorption is very large, so the vibration resistance by vibration energy absorption is very good.

이상에서 설명한 바와 같이, 본 발명에 따른 경량 단열 우레탄폴 콘크리트는, 폐 냉장고에 들어있는 폐 우레탄폼을 수거하여 이를 단열 콘크리트의 시공 자재로 활용하므로서, 건축 및 토목분야의 경량성 단열 콘크리트로 시공할 수 있는 특징이 있으며, 자원 재활용 측면에서도 매우 경제적인 잇점이 있다.As described above, the lightweight insulating urethane pole concrete according to the present invention, by collecting the waste urethane foam contained in the waste refrigerator and using it as a construction material of the insulating concrete, it can be constructed as lightweight insulating concrete in the construction and civil engineering There are many advantages, and it is very economical in terms of resource recycling.

다시 말해서, 본 발명에 따른 경량 단열 우레탄폴 콘크리트는, 폐스티로폴에 고품질인 단열재 우레탄을 특수 파쇄하여 적정량 혼합하여 차음, 균열방지효과, 단열성과 강도를 한층 높였으며, 이 재료에 본 출원인이 개발한 PPS 혼화제를 첨가하여 재료분리 및 유동화성을 키워서 현존하는 폴콘크리트 시공방식에서 야기되는 재료의 날림, 시공표면 폴날림, 소형 리어카 믹서기 작업시 타공정의 시공물 파손(벽체 석고보드, 문틀 프레임, 새시 등의 파손), 배합의 불균질성 등의 단점을 최소화하였다.In other words, the lightweight insulating urethane pole concrete according to the present invention, by specially crushing the high-quality insulation urethane in the waste styropole mixed with an appropriate amount to increase the sound insulation, crack prevention effect, heat insulation and strength, and developed by the present applicant to this material PPS admixture is added to increase the material separation and fluidization, resulting in the flying of materials caused by the existing pole concrete construction method, the construction surface falling, and the damage of the construction of other processes when working with a small rear car mixer (wall plasterboard, door frame, chassis). Breakage of the back and the like, heterogeneity of the formulation and the like.
