본 발명은 발포성 소각 잔재물을 이용한 칸막이용 비내력 벽체 조성물에 관한 것으로서, 보다 상세하게는 발포성 소각 잔재물을 이용하여 시멘트 경화체 내부에 발포조직을 형성하여 경량이면서 방음과 단열 효과가 우수하고 화재 시 유독가스를 방출하지 않는 칸막이용 비내력 벽체 조성물에 관한 것이다.

By using foamable incineration residues to form a foam structure inside the cement hardening body, it is lightweight, has excellent soundproofing and heat insulation effects, and produces no toxic gases in the event of a fire. It relates to a non-load-bearing wall composition for partitions that does not emit .

일반적으로 건설현장에서 널리 사용되는 ALC(Auto Lightweight Concrete) 블록은 석회와 규사를 혼합한 원료에 물과 발포제(알루미늄 분말)를 넣고 고온고압(180℃, 10기압, 12시간 이상) 상태의 오토클레이브 양생을 통해 생산된다. ALC 블록은 일반 콘크리트보다 4 내지 5배 정도 가벼워(표준비중 0.5 수준) 구조 비용을 절감할 수 있으며, 내진설계나 고층건물 시공에 유리한 장점을 나타낸다.ALC (Auto Lightweight Concrete) blocks, which are generally widely used in construction sites, are made by adding water and a foaming agent (aluminum powder) to a raw material mixed with lime and silica sand and autoclaving it at high temperature and pressure (180℃, 10 atmospheres, 12 hours or more). It is produced through curing. ALC blocks are 4 to 5 times lighter than regular concrete (standard specific gravity of about 0.5), which reduces structural costs and is advantageous for earthquake-resistant design and high-rise building construction.

그러나, 종래에 ALC 블록은 생산과정이 복잡하기 때문에 제조비용이 고가이며, 특수한 장비가 요구된다. 경량성과 강도를 확보하기 위해 고온고압상태(180℃, 10기압)의 오토클레이브 증기 양생이 필수적으로 진행되어야 한다. 또한, 증기 양생한 샘플을 일정한 치수로 절단할 수 있는 고성능 절단기 등의 대형 설비들이 요구되며, 이러한 설비들을 보관할 수 있는 대규모 시설도 필요한 상황이며 초기 투자 비용이 워낙 고가이기 때문에 국내에서는 대기업에서만 생산하고 있는 실정이다. However, conventional ALC blocks are expensive to manufacture because the production process is complex, and special equipment is required. To ensure lightness and strength, autoclave steam curing at high temperature and high pressure (180°C, 10 atm) must be performed. In addition, large-scale equipment such as high-performance cutting machines that can cut steam-cured samples to a certain size are required, and large-scale facilities to store these equipment are also needed. Since the initial investment cost is very high, only large companies produce them in Korea. There is a situation.

또한, 불안정한 잔골재(규사) 수급으로 인한 불가피한 제품 가격 상승을 초래하며, 국토교통부 제5차 골재수급 기본계획(2014-2018)에 따르면, 천연자원인 골재(규사)의 보존량이 지속적으로 감소함과 더불어 환경규제 및 주민들의 반대로 인해서 골재 채취에 어려움이 있는 상황이다. 따라서, ALC 블록을 제조하기 위해 필요한 원재료인 규사가 고갈되어가는 상황에서, 재료 단가 상승으로 인한 제품 가격 상승이 불가피한 상황이다.In addition, the unstable supply of fine aggregate (silica sand) causes an inevitable increase in product prices, and according to the 5th Basic Aggregate Supply and Demand Plan of the Ministry of Land, Infrastructure and Transport (2014-2018), the amount of preserved aggregate (silica sand), a natural resource, continues to decrease. In addition, there are difficulties in collecting aggregates due to environmental regulations and opposition from residents. Therefore, in a situation where silica sand, a raw material needed to manufacture ALC blocks, is being depleted, an increase in product prices due to an increase in material costs is inevitable.

따라서, ALC와 같이 고온고압의 양생과정 없이 기포제 등을 혼입하여 상온에서 경량콘크리트 블록이나 패널을 생산할 수 있는 기술 개발이 필요하나 경량성과 강도를 동시에 만족시키기 위해서는 혼입되는 원재료의 가격이 높거나 ALC 제품 대비 내화 성능이 부족한 문제가 제기되고 있다.Therefore, it is necessary to develop a technology that can produce lightweight concrete blocks or panels at room temperature by mixing foaming agents without a high temperature and high pressure curing process like ALC. However, in order to satisfy both lightness and strength, the price of the raw materials mixed is high or ALC products are used. A problem is being raised about insufficient fire resistance performance.

일례로, 현재 일부 건설현장에서 사용되고 있는 경량콘크리트 패널은 발포 폴리스티렌 경량콘크리트 복합패널로 불리는 것으로서 3.2mm 또는 4.5mm의 두께를 가진 시멘트보드를 표면재로 하여 그 사이에 시멘트와 폴리스티렌에 물과 유동화제를 혼입한 경량 콘크리트를 넣어서 양생한 제품이다. 기존의 발포 폴리스티렌 경량 콘크리트 복합 패널은 중앙부에 폴리스티렌 비드와 시멘트 혼합물을 주원료로 사용하고 표면에 섬유보강 시멘트보드 접합하여 만들도록 규정된 패널이다. 현재까지 이러한 복합 패널은 흰색의 발포 폴리스티렌 비드를 사용하여 회색의 콘크리트와 혼합함으로써 색상이 눈에 띄어 시각적으로 거부감이 발생하였다. For example, the lightweight concrete panel currently used in some construction sites is called expanded polystyrene lightweight concrete composite panel, which is made of cement board with a thickness of 3.2mm or 4.5mm as the surface material, and water and fluidizing agent are added to the cement and polystyrene in between. It is a product cured by adding mixed lightweight concrete. The existing expanded polystyrene lightweight concrete composite panel is a panel specified to be made by using a polystyrene bead and cement mixture as the main raw material in the center and joining fiber-reinforced cement board on the surface. To date, these composite panels have been made using white expanded polystyrene beads mixed with gray concrete, making the color stand out and causing visual rejection.

이러한 문제를 해결하기 위한 기술의 일예가 하기 문헌 1에 개시되어 있다. 하기 특허문헌 1에는 저회와 시멘트 및 발포 폴리스티렌 비드를 혼합하는 혼합물 준비단계와, 준비된 혼합물을 형틀에 주입하는 형틀 주입단계와, 형틀에 주입된 혼합물을 양생하는 실내 양생단계와, 실내 양생된 혼합물을 형틀에서 분리하는 형틀 분리단계와, 형틀에서 분리되는 혼합물을 양생하는 실외 양생단계와, 혼합물과 분리된 형틀을 청소하여 다시 조립하는 형틀 청소 조립단계를 포함하여 이루어지고, 상기 혼합물 준비단계에서 발포 폴리스티렌 비드는 흑연이 일정량 함침되는 것을 특징으로 하는 흑연발포폴리스티렌 비드를 사용한 경량콘크리트 패널에 대해 개시되어 있다. 상기 흑연발포폴리스티렌 비드를 사용한 경량콘크리트 패널은 발포 폴리스티렌 비드의 색상이 콘크리트의 색상과 유사해져 색상차이에 의한 시각적인 거부감이 해소되고, 종래의 발포 폴리스티렌 경량 콘크리트 복합 패널보다 열전도율이 낮아져 단열 성능을 향상시키며, 2시간동안 불에 견딜 수 있는 패널의 최소두께가 얇아져 동급제품에 비해 가벼워지는 단열 및 내화성능이 향상된 것이 특징이다.An example of a technology to solve this problem is disclosed in Document 1 below. Patent Document 1 below includes a mixture preparation step of mixing bottom ash, cement, and expanded polystyrene beads, a mold injection step of injecting the prepared mixture into a mold, an indoor curing step of curing the mixture injected into the mold, and an indoor cured mixture. It includes a mold separation step of separating from the mold, an outdoor curing step of curing the mixture separated from the mold, and a mold cleaning and assembly step of cleaning the mold separated from the mixture and reassembling it, and in the mixture preparation step, expanded polystyrene A lightweight concrete panel using graphite expanded polystyrene beads is disclosed, wherein the beads are impregnated with a certain amount of graphite. In the lightweight concrete panel using the graphite expanded polystyrene beads, the color of the expanded polystyrene beads is similar to the color of concrete, eliminating visual discomfort due to color differences, and improving thermal insulation performance by lowering the thermal conductivity than the conventional expanded polystyrene lightweight concrete composite panel. The minimum thickness of the panel that can withstand fire for 2 hours has become thinner, making it lighter than similar products, and improving insulation and fire resistance performance.

그러나, 상술한 바와 같은 종래의 기술은 제조 시 경량성 확보를 위해 발포 폴리스티렌 비드와 같은 유기물을 사용하기 때문에 화재 발생 시 유해가스가 발생할 위험이 있다. However, since the conventional technology as described above uses organic materials such as expanded polystyrene beads to ensure lightness during manufacturing, there is a risk of generating harmful gases in the event of a fire.

또한, 경량성 확보를 위해 또 다른 기술로는 무기계 소재인 팽창 펄라이트나 팽창 질석을 사용하는 경량콘크리트 블록 및 패널 제조기술이 소개되나 원재료인 팽창 펄라이트나 팽창 질석의 단가가 높아 ALC 제품 대비 가격 경쟁력이 부족한 상황이다.In addition, in order to secure lightness, another technology has been introduced to manufacture lightweight concrete blocks and panels using expanded perlite or expanded vermiculite, which are inorganic materials. However, due to the high unit price of expanded perlite or expanded vermiculite, which are raw materials, the price is not competitive compared to ALC products. The situation is lacking.

또한, 경량성 확보를 위해 화학 혼화제인 기포제 등을 사용하여 자체 경량성을 확보하고 상온이나 상압 증기 양생이 가능한 CLC(Cellular Lightweight Concrete) 블록이나 패널기술 들이 개발되고 있다. 그러나 화학 혼화제인 기포제의 가격이 높아 ALC 제품 대비 가격 경쟁력이 부족한 상황이며 경량성 확보를 위해 과도한 기포제 사용으로 경화가 늦어져 양생시간이 길어져 생산성이 저하되는 문제점을 가지고 있다. In addition, CLC (Cellular Lightweight Concrete) block or panel technologies are being developed that secure lightweight properties by using foaming agents, which are chemical admixtures, to secure lightweight properties and that can be cured with steam at room temperature or pressure. However, the price of the foaming agent, a chemical admixture, is high, so it lacks price competitiveness compared to ALC products, and curing is slowed due to excessive use of the foaming agent to ensure lightness, resulting in longer curing times and lower productivity.

따라서, 가격이 저렴하면서도 시멘트의 수화반응을 저해하지 않아 경화시간이 짧게 소요되고 고온에서도 유독가스를 발생하지 않으며 발포조직 사이의 결합력이 우수한 경량 시멘트 제조 기술을 개발할 필요가 있다. Therefore, there is a need to develop a lightweight cement manufacturing technology that is inexpensive, does not inhibit the hydration reaction of cement, requires a short curing time, does not generate toxic gases even at high temperatures, and has excellent bonding between foam structures.

이에, 본 발명자들은 종래 문제점을 해결하고자 노력한 결과, 물과 반응 시 자체 팽창성이 강해 오히려 높은 압축강도를 요구하는 콘크리트 제품에 활용이 불가능하였던 발포성 소각 잔재물을 이용하여 시멘트 경화체 내부에 발포조직을 형성하여 경량이면서 방음과 단열 효과가 우수하고 화재 시 유독가스를 방출하지 않는 칸막이용 비내력 벽체 조성물을 제공함으로써, 본 발명을 완성하였다. Accordingly, the present inventors attempted to solve the conventional problem by forming a foam structure inside the cement hardening body using foamable incineration residues, which had strong self-expanding properties when reacting with water and thus could not be used in concrete products requiring high compressive strength. The present invention was completed by providing a non-load-bearing wall composition for partitions that is lightweight, has excellent soundproofing and thermal insulation effects, and does not emit toxic gases in the event of a fire.

In addition, for 100 parts by weight of the foamable incineration residue, the combustion residue discharged from a circulating fluidized bed boiler that mixes fuel and limestone and contains 20 to 70% by weight of CaO and 3 to 35% by weight of SO 3 content is 1 It is characterized by additional mixing of ~100 parts by weight.

본 발명의 칸막이용 비내력 벽체 조성물은 경량 효과를 증진시키기 위하여, 상기 발포성 연소 및 소각 잔재물 100중량부에 대하여, 기포제를 0.1∼5중량부 더 혼입하며, 상기 기포제는 동물성 기포제, 식물성 기포제 및 과산화수소로 이루어진 군에서 선택된 어느 하나 또는 둘 이상의 혼합물을 사용하는 것이다.

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

본 발명은 발포성 소각 잔재물 100중량부에 대하여, 시멘트 5∼500중량부를 포함하는 의 칸막이용 비내력 벽체 조성물을 제공한다.The present invention provides a non-load-bearing wall composition for partitions containing 5 to 500 parts by weight of cement based on 100 parts by weight of foamable incineration residue.

상기 발포성 소각 잔재물은 일반 고형연료(SRF, Solid Refuse Fuel), 바이오 고형연료(BIO-SRF, Biomass-Solid Refuse Fuel), 생활 폐기물 및 사업장 폐기물로 이루어진 군에서 선택되는 어느 하나 또는 둘 이상의 혼합물이고, 이들을 소각 시 발생되는 잔재물인 것이다. The foamable incineration residue is any one or a mixture of two or more selected from the group consisting of general solid fuel (SRF, Solid Refuse Fuel), bio-solid fuel (BIO-SRF, Biomass-Solid Refuse Fuel), household waste, and industrial waste, These are residues generated when incinerated.

상기 발포성 소각 잔재물은 물을 1 : 0.5∼1 중량비로 혼합한 후 24시간 이내에 혼합 직후 원체적에 비해 20∼400% 체적이 더 팽창하는 것이다. The foamable incineration residue expands by 20 to 400% in volume compared to the original volume immediately after mixing within 24 hours after mixing with water at a weight ratio of 1:0.5 to 1.

도 1은 본 발명의 발포성 소각 잔재물과 물 1:1 혼합한 후 24시간 경과한 체적변화를 관찰한 사진으로서, 약 200% 이상의 체적팽창 현상을 확인할 수 있다. Figure 1 is a photograph observing the volume change 24 hours after mixing the foamable incineration residue of the present invention with water 1:1, and a volume expansion phenomenon of about 200% or more can be confirmed.

상기 발포성 소각 잔재물은 물과 반응시 수소가스나 암모니아 가스 등을 방출함으로써 자체 기포가 발생되어 높은 압축강도를 요구하는 콘크리트 등에 사용 시 과도한 팽창을 일으켜 활용이 불가능하나 본 발명의 목적과 같이 경량성을 요구하는 제품에는 별도의 기포제나 발포제 사용 없이도 자체 기포 형성이 가능한 장점을 가지고 있다. 이러한 자체 기포 발생 현상은 자체 소각 잔재물에 함유된 금속 이온 성분이 물과 반응 시 발생되는 수소가스 성분과 소각로에서 질소 산화물의 대기 방출을 억제시키기 위해 대기방지 시설에서 요소수나 액상 암모니아 분무에 의해 소각 잔재물에 함유되어 있는 질소 화합물 성분이 물과 반응 시 암모니아 가스 형태로 방출되기 때문이다.When the foamable incineration residue reacts with water, it emits hydrogen gas or ammonia gas, which generates its own bubbles, causing excessive expansion when used in concrete that requires high compressive strength, making it unusable. However, for the purpose of the present invention, it is lightweight. The required product has the advantage of being able to form its own bubbles without the use of a separate foaming agent or foaming agent. This phenomenon of self-bubble generation occurs when metal ions contained in self-incineration residues react with water and the incineration residues are sprayed with urea water or liquid ammonia in an atmosphere prevention facility to suppress the release of hydrogen gas components and nitrogen oxides from the incinerator into the atmosphere. This is because the nitrogen compounds contained in are released in the form of ammonia gas when reacting with water.

또한, 발포성 소각 잔재물 자체 염화나트륨, 염화칼슘, 염화마그네슘, 염화칼륨과 같은 염화물 성분을 2∼20% 정도 함유하고 있어, 시멘트의 수화반응을 촉진시키는 역할을 수행하여 최소한의 양생시간으로도 강도 발현이 가능한 특징을 발휘한다. In addition, the foamable incineration residue itself contains about 2-20% of chloride components such as sodium chloride, calcium chloride, magnesium chloride, and potassium chloride, which plays a role in promoting the hydration reaction of cement, allowing strength to be developed even with a minimum curing time. exerts

상기 발포성 소각 잔재물 100중량부에 대하여, 시멘트 5∼500중량부를 포함하는 것을 바람직한데 이때 시멘트 5중량 미만일 경우에는 강도 발현이 어렵고, 시멘트 중량이 500중량부를 초과할 경우에는 상대적으로 발포성 소각 잔재물의 중량이 감소하여 기포 발생이 감소되어 경량성 확보가 어렵게 된다.It is preferable to include 5 to 500 parts by weight of cement for 100 parts by weight of the foamable incineration residue. In this case, if the weight of cement is less than 5 parts, it is difficult to develop strength, and if the weight of cement exceeds 500 parts by weight, the weight of the foamable incineration residue is relatively high. This decreases the generation of air bubbles, making it difficult to secure lightweight properties.

또한, 상기 시멘트는 플라이애시 시멘트, 고로슬래그 시멘트, 보통포틀랜드 시멘트, 준조강 포틀랜드 시멘트, 조강 포틀랜드 시멘트, CSA(Calcium Sulfur Aluminate), C12A7, 알루미나 시멘트, 초속경 시멘트 중 어느 하나 또는 둘 이상의 혼합물인 것이 바람직하다. 특히, CSA(Calcium Sulfur Aluminate), C12A7, 알루미나 시멘트, 초속경 시멘트를 일부 혼합하여 사용할 경우에는 원재료의 가격은 높으나 별도의 양생시설 없이도 제품 생산이 가능한 장점이 있다. In addition, the cement is any one or two or more of fly ash cement, blast furnace slag cement, ordinary Portland cement, semi-precipitated steel Portland cement, early steel Portland cement, CSA (Calcium Sulfur Aluminate), C 12 A 7 , alumina cement, and ultra-fast hardening cement. It is preferable that it is a mixture. In particular, when using a mixture of CSA (Calcium Sulfur Aluminate), C 12 A 7 , alumina cement, and ultra-fast hardening cement, the price of raw materials is high, but the product can be produced without separate curing facilities.

또한, 상기 발포성 소각 잔재물 100중량부에 대하여, 고로슬래그 미분말을 5∼500중량부 더 혼입하는 것이 바람직하다. 고로슬래그 미분말은 시멘트를 대체할 수 있는 잠재수경성 재료로 순환자원 활용에 따른 원가절감에 효과적이며 장기강도 발현에도 더욱 유리하다. 상기 발포성 소각 잔재물 100중량부에 대하여, 고로슬래그 미분말을 5 중량부 미만일 경우 그 효과가 없으며, 500중량부를 초과할 경우 상대적으로 발포성 소각 잔재물의 중량이 감소하여 기포 발생이 감소되어 경량성 확보가 어렵게 된다. In addition, it is preferable to further mix 5 to 500 parts by weight of blast furnace slag fine powder with respect to 100 parts by weight of the foamable incineration residue. Blast furnace slag fine powder is a potential hydraulic material that can replace cement, which is effective in reducing costs by utilizing recycled resources and is also more advantageous in developing long-term strength. If the amount of blast furnace slag fine powder is less than 5 parts by weight relative to 100 parts by weight of the foamable incineration residue, the effect is ineffective, and if it exceeds 500 parts by weight, the weight of the foamable incineration residue is relatively reduced, thereby reducing the generation of bubbles, making it difficult to secure lightness. do.

또한, 본 발명의 칸막이용 비내력 벽체 조성물에는 상기 발포성 소각 잔재물 100중량부에 대하여, 제철소에서 배출되며 Na2O 함량이 35∼50중량%, SO3 함량이 35∼50중량%를 포함하는 중조 탈황 분진을 1∼100중량부 더 혼입하는 것이 바람직하다. 상기 중조 탈황 분진은 황산나트륨 성분과 염화물 성분이 함유되어 있어 시멘트의 수화반응을 촉진하는 역할과 더불어 고로슬래그 미분말이 같이 사용될 경우 잠재수경성을 발휘할 수 있게 하는 자극제 역할을 수행한다. 이때, 상기 발포성 소각 잔재물 100중량부에 대하여, 중조 탈황 분진을 1중량부 미만일 경우 그 효과가 없으며 100중량부 초과할 경우 오히려 강도 발현이 어렵고 경량성 확보 또한 어렵게 된다.In addition, the non-load-bearing wall composition for partitions of the present invention includes sodium bicarbonate discharged from a steel mill and containing 35 to 50% by weight of Na 2 O and 35 to 50% by weight of SO 3 based on 100 parts by weight of the foamable incineration residue. It is preferable to add 1 to 100 parts by weight of desulfurization dust. The sodium bicarbonate desulfurization dust contains sodium sulfate and chloride components, which not only promotes the hydration reaction of cement, but also acts as a stimulant to demonstrate hydraulic potential when used together with fine powder of blast furnace slag. At this time, if the sodium bicarbonate desulfurization dust is less than 1 part by weight relative to 100 parts by weight of the foamable incineration residue, the effect is ineffective, and if it exceeds 100 parts by weight, it is difficult to develop strength and secure lightness.

또한, 상기 발포성 소각 잔재물 100중량부에 대하여, 유리 제조 및 가공 공정에서 배출되며 CaO 함량이 25∼38중량%, Na2O 함량이 15∼25중량%, SO3 함량이 35∼50중량%를 포함하는 공정 분진을 1∼100중량부 더 혼입하는 것이 바람직하다. 상기 공정 분진은 황산나트륨, 황산칼슘 성분으로 구성되어 있어 시멘트의 수화반응을 촉진하는 역할과 더불어 고로슬래그 미분말이 같이 사용될 경우 잠재수경성을 발휘할 수 있게 하는 자극제 역할을 수행한다. 이때, 상기 발포성 소각 잔재물 100중량부에 대하여 공정분진 1중량부 미만일 경우 그 효과가 없으며 100중량부 초과할 경우 오히려 강도 발현이 어렵고 경량성 확보 또한 어렵게 된다.In addition, with respect to 100 parts by weight of the foamable incineration residue, which is discharged from the glass manufacturing and processing process, the CaO content is 25 to 38% by weight, the Na 2 O content is 15 to 25% by weight, and the SO 3 content is 35 to 50% by weight. It is preferable to further mix 1 to 100 parts by weight of process dust. The process dust is composed of sodium sulfate and calcium sulfate components, which not only promotes the hydration reaction of cement, but also acts as a stimulant to demonstrate hydraulic potential when used together with fine powder of blast furnace slag. At this time, if the amount of process dust is less than 1 part by weight per 100 parts by weight of the foamable incineration residue, there is no effect, and if it exceeds 100 parts by weight, it is difficult to develop strength and secure lightness.

또한, 본 발명의 칸막이용 비내력 벽체 조성물에는 상기 발포성 소각 잔재물 100중량부에 대하여, 연료와 석회석을 혼합 연소하는 순환 유동층 보일러에서 배출되며 CaO 함량이 20∼70중량%, SO3 함량이 3∼35중량%를 포함하는 연소 잔재물을 1∼100중량부 더 혼입하는 것을 특징으로 하는 것이 바람직하다. 상기 연소 잔재물은 순수 CaO 성분과 CaSO4 성분이 존재하여 생석회 성분이 물과 반응시 자체 발열효과가 있고 무수석고 성분에 의해 시멘트 및 고로슬래그 미분말의 수화반응을 촉진시키는 역할을 수행한다. 상기 발포성 소각 잔재물 100중량부에 대하여 연소 잔재물 1중량부 미만일 경우 그 효과가 없으며 100중량부 초과할 경우 오히려 강도 발현이 어렵고 경량성 확보 또한 어렵게 된다. In addition, the non-load-bearing wall composition for partitions of the present invention has a CaO content of 20 to 70% by weight and an SO 3 content of 3 to 70% by weight, which is discharged from a circulating fluidized bed boiler that mixes and burns fuel and limestone, based on 100 parts by weight of the foamable incineration residue. It is preferable to further incorporate 1 to 100 parts by weight of combustion residues containing 35% by weight. The combustion residue contains pure CaO and CaSO 4 components, so it has a self-heating effect when the quicklime component reacts with water, and the anhydrous gypsum component plays a role in promoting the hydration reaction of cement and blast furnace slag fine powder. If the amount of combustion residue is less than 1 part by weight per 100 parts by weight of the foamable incineration residue, the effect is ineffective, and if it exceeds 100 parts by weight, it is difficult to develop strength and secure lightness.

또한, 경량 효과를 증진시키기 위하여 상기 발포성 연소 및 소각 잔재물 100중량부에 대하여, 기포제를 0.1∼5중량부 더 혼입하며, 상기 기포제는 동물성 기포제, 식물성 기포제, 과산화수소 중 선택된 어느 하나 또는 둘 이상의 혼합물인 것이 바람직하다. 0.1 중량부 미만일 경우 그 효과가 없으며 5 중량부 초과일 경우 경량성 확보에는 더욱 유리하나 강도가 급격하게 저하되는 문제점이 발생한다.In addition, in order to improve the lightweight effect, 0.1 to 5 parts by weight of a foaming agent is further added to 100 parts by weight of the foamable combustion and incineration residue, and the foaming agent is one or a mixture of two or more selected from animal foaming agent, vegetable foaming agent, and hydrogen peroxide. It is desirable. If it is less than 0.1 parts by weight, there is no effect, and if it is more than 5 parts by weight, it is more advantageous to ensure lightness, but the problem occurs that the strength rapidly decreases.

또한, 경량 효과를 증진시키기 위하여 상기 발포성 소각 잔재물 100중량부에 대하여, 팽창질석 또는 팽창퍼라이트가 50중량% 이상 함유되어 있는 폐보온단열재를 분쇄하여 입경 20mm 이하로 조정된 경량골재를 0.1∼200중량부 더 혼입된 것이 바람직하다. 상기 높은 온도를 유지해야 하는 석유화학산업단지 등의 플랜트 배관 단열을 위해 팽창질석 및 팽창퍼라이트 계열의 보온재가 많이 사용되고 있으나 배관 교체 공사 시 많은 양의 폐보온단열재가 발생하게 된다. 현재는 폐보온단열재는 주성분이 팽창질석 또는 팽창퍼라이트이며 결합재로 규산소다가 사용되고 및 보강재로 유기질 단섬유로 이루어져 있으나 폐기 시 이의 별도 분리가 어려워 현재는 재활용이 되지 않아 전량 매립을 하고 있다. 하지만 자체 밀도가 매우 낮아 부피를 워낙 많이 차지하기 때문에 매립에 있어 큰 비용을 지불하고 있는 실정이다. 이를 별도의 분리과정 없이 단순 분쇄하여 본 발명의 비내력 벽체 조성물로 활용한다면 경량성 확보에 매우 유리할 뿐만 아니라 폐보온단열재에 함유된 보강섬유에 의해 인장력 및 휨강도를 증가시키는 역할을 수행할 수 있다. 상기 폐보온단열재 경량골재가 0.1 중량부 미만일 경우 그 효과가 없으며 200중량부 초과일 경우 경량성 확보에는 더욱 유리하나 강도가 급격하게 저하되는 문제점이 발생한다. In addition, in order to improve the lightweight effect, 0.1 to 200 weight of lightweight aggregate adjusted to a particle size of 20 mm or less by pulverizing waste thermal insulation material containing more than 50% by weight of expanded vermiculite or expanded perlite is added to 100 parts by weight of the foamable incineration residue. It is preferable that more parts are mixed. Expanded vermiculite and expanded perlite-based insulation materials are widely used to insulate plant pipes in petrochemical industrial complexes, etc., where high temperatures must be maintained. However, a large amount of waste insulation material is generated during pipe replacement construction. Currently, waste thermal insulation materials are made up of expanded vermiculite or expanded perlite as main ingredients, sodium silicate is used as a binder, and organic short fibers are used as reinforcing materials. However, it is difficult to separate them when disposing of them, so they are not currently recycled and are landfilled entirely. However, since its density is very low and it takes up a lot of volume, it is paying a large cost for landfill. If this is simply pulverized without a separate separation process and used as a non-load-bearing wall composition of the present invention, it is not only very advantageous in securing lightness, but also plays a role in increasing tensile force and bending strength by the reinforcing fibers contained in the waste thermal insulation material. If the lightweight aggregate of the waste thermal insulation material is less than 0.1 parts by weight, it has no effect, and if it exceeds 200 parts by weight, it is more advantageous to ensure lightness, but a problem occurs in which the strength rapidly decreases.

또한, 재료 분리를 방지하기 위하여 상기 발포성 소각 잔재물 100중량부에 대하여, 증점제 0.01∼20중량부를 더 포함하는 것이 바람직하다. 0.01중량부 미만일 경우 그 효과가 미비하며 20중량부를 초과할 경우 점성이 너무 강해져 벽체 성형이 어렵게 된다. In addition, in order to prevent material separation, it is preferable to further include 0.01 to 20 parts by weight of a thickener based on 100 parts by weight of the foamable incineration residue. If it is less than 0.01 parts by weight, the effect is minimal, and if it exceeds 20 parts by weight, the viscosity becomes too strong, making wall molding difficult.

또한, 휨 및 인장강도를 개선시키기 위하여 상기 발포성 소각 잔재물 100중량부에 길이 0.5∼25mm 단섬유를 0.01∼20중량부를 더 포함하는 것이 바람직하다. 상기 단섬유가 0.01중량부 미만일 경우 그 효과가 미비하며 20중량부를 초과할 경우 섬유 뭉침 현상이 발생하여 벽체 성형이 어렵게 된다. In addition, in order to improve bending and tensile strength, it is preferable to further include 0.01 to 20 parts by weight of short fibers with a length of 0.5 to 25 mm per 100 parts by weight of the foamable incineration residue. If the single fiber is less than 0.01 parts by weight, the effect is minimal, and if it exceeds 20 parts by weight, fiber agglomeration occurs, making wall forming difficult.

이하에서 본 발명의 바람직한 실시예 및 비교예들이 기술되어질 것이다. 또한 이하의 실시예들은 본 발명을 예증하기 위한 것으로서 본 발명의 범위를 국한하는 것으로 이해되어져서는 아니된다.Preferred examples and comparative examples of the present invention will be described below. Additionally, the following examples are intended to illustrate the present invention and should not be construed as limiting the scope of the present invention.
