Description

대기 및 수질정화작용을 갖는 기능성 콘크리트블록{The functionalconcrete block purficating the air and water}The functional concrete block purficating the air and water

본 발명은 대기 및 수질정화작용을 갖는 기능성 콘크리트블록에 관한 것으로 구체적으로는 블록의 몸체에는 다공성물질의 첨가로 대기중에서는 보온성, 방음성, 탈취성, 항균성, 원적외선 방사기능을 갖게되고 수중에서는 보수성, 흡착 또는 여과기능에 의한 수질정화작용을 갖게되며 블록의 표면에는 광촉매를 함유한 수경화성조성물이 코팅되므로서 유기물 분해기능에 의해 대기 정화작용 및 수질정화작용을 동시에 갖는 기능성 콘크리트블록에 관한 것이다.The present invention relates to a functional concrete block having an air and water purification action. Specifically, the body of the block has a thermal insulation, soundproofing, deodorizing property, antibacterial activity, far-infrared radiation function in the air by the addition of a porous material, and conservativeness in water. It has a water purification function by adsorption or filtration, and the surface of the block is coated with a water-curable composition containing a photocatalyst, and thus a functional concrete block having both an air purification function and a water purification function by an organic matter decomposition function.

본 발명에서 다공성의 물질이라함은 숯, 일라이트, 퍼얼라이트, 흑요석, 장호석, 화산석, 질석, 頁岩(혈암)의 분말들로서 다공성이면서 경량성을 가진 물질분말들이다. 또한 블록표면에 우수한 대기 및 수질정화기능을 갖는 코팅층이라 함은 광촉매 또는 광촉매가 담지된 물질, 광촉매의 광석분말로 조성한 코팅액을 블록표면에 코팅접착시켜 경화시킨층이라 할 수 있다.
In the present invention, the porous material is a powder of charcoal, illite, pearlite, obsidian, jangho stone, volcanic stone, vermiculite, and shale, which are porous and lightweight. In addition, a coating layer having excellent air and water purification functions on a block surface may be a layer obtained by coating and curing a coating liquid formed of a photocatalyst or a photocatalyst-carrying material or a photocatalyst ore powder onto a block surface.

최근 우리나라는 괄목할만한 산업화를 달성했지만 이에 따른 부작용으로 심각한 환경공해를 유발시킨 것도 사실이다. 수질의 경우에는 화학적산소요구량(COD), 생물학적산소요구량이 심각한 상태이고 각종폐수에는 인체에 유해한 유기물 및 무기물이 용해되어 있으며, 특히 질소산화물, 인화합물, 부유물들을 응집처리하여 슬러지를 제거시키는 처리비용이 또한 엄청나며, 슬러지의 량도 해마다 높은 비율로 증가하고 있다.Recently, Korea has achieved remarkable industrialization, but it is also true that side effects caused severe environmental pollution. In the case of water quality, chemical oxygen demand (COD) and biological oxygen demand are serious, and various wastewater contains organic and inorganic substances harmful to the human body.In particular, the cost of treating sludge by flocculating nitrogen oxides, phosphorus compounds, and suspended solids. This is also enormous, and the sludge volume is increasing at a high rate each year.

또한 대기오염의 경우에도 사무실이나 주거생활공간에 합성수지건축자재, 합성수지접착제, 합성수지도료 등을 사용하므로서 각종 휘발성 유기화합물(VOC), 공장에서 발생되는 질소산화물, 황산화물 기타유해개스에 노출되므로서 호흡기질환, 아토피성 피부질환이 적지 않게 발생하고 있는 상황이다.In addition, even in the case of air pollution, it is exposed to various volatile organic compounds (VOC), nitrogen oxides, sulfur oxides, and other harmful gases by using synthetic resin materials, synthetic resin adhesives, and synthetic resins in offices and residential living spaces. A lot of diseases and atopic dermatitis are occurring.

따라서 구조물로서 물과 대기와의 접촉빈도가 큰 콘크리트를 이용하여 대기 또는 수중의 오염물질을 분해감소시킬 수 있는 소재를 콘크리트제품에 적용하는 것이 매우 효과적인 방법이라 할 수 있으며 또한 콘크리트제품에 유해물질의 저감기능을 부여하는 방법 또한 이와 같은 맥락에서 이미 다양하게 연구되고 있으며 그 제품 또한 출시되고 있다.Therefore, it is a very effective way to apply concrete materials to concrete products that can decompose or reduce pollutants in the air or water using concrete that has frequent contact between water and air as structures. Methods for imparting mitigation are already being studied in this context, and their products are also on the market.

그중 괄목할만한 것은 광촉매로서 광촉매는 빛에 의해 각종 유기물 및 미생물을 분해할 수 있는 물질로서 외부에서 다른 에너지의 유입 없이 태양에너지만을 이용하여 대기오염물질이나 수질오염물질을 분해할 수 있는 물질이다.Among them, the photocatalyst is a photocatalyst that can decompose various organic matters and microorganisms by light, and is a substance that can decompose air pollutants or water pollutants using only solar energy without introducing other energy from the outside.

이와 같은 광촉매는 특유의 자기정화능력 때문에 1990년대 중반부터 일본 등을 중심으로하여 콘크리트와 같은 건축자재에 적용하고 대기정화, 수질정화에 이용하려는 연구가 진행되어 왔으며, 일본에서는 광촉매 콘크리트공업화까지 설립되어 동경 및 사이타마 등의 도로 등에 실제 시공되어 도시의 공기정화에 일조하고 있다. 그러나 우리나라는 아직 실험수준에서 연구되고 있고 광촉매가 적용된 콘크리트와 건축 외장재가 소개되고 있긴 하나 실용화되어 활성화되기까지는 부단한 연구와 개발이 절실하게 요구되고 있다.Such photocatalyst has been researched to apply to building materials such as concrete, atmospheric purification and water purification since the mid-1990s because of its unique self-purifying ability.In Japan, photocatalyst concrete industrialization has been established. It is actually installed in roads such as Tokyo and Saitama to help clean the air of the city. However, Korea is still being studied at the experimental level, and concrete and building exterior materials with photocatalysts are introduced, but constant research and development are urgently required before they can be used and activated.

본건 발명과 관련된 기술분야의 종래기술을 알아보면,Looking at the prior art in the technical field related to the present invention,

국내등록특허공보(등록번호 제942990호)에는 "재생기능성 다공성입자를 이용한 콘크리트구조체 성형용 모르타르의 제조방법 및 그 구조체"에 관한 기술내용으로 이는 목탄입자를 포함하는 다공성입자에 초미세광촉매 미세분말을 코팅시킨 광촉매코팅 다공성입자를 시멘트입자보다 큰 입자로 조정하여 시멘트, 골재첨가제 수경화반응수로 조성되는 콘크리트 모르타르에 첨가해서되는 기능성 다공입자를 이용한 콘크리트구조체 성형용 콘크리트 모르타르 제조방법과 그 구조체에 관한 기술로서 광촉매 미세분말이 코팅된 다공성입자를 콘크리트 구조체를 성형하는 콘크리트 모르타르 전체에 균일하게 분산된 상태로 존재케하므로써 다공성물질과 광촉매에 의하여 경량화의 목적, 공기정화 수질정화기능을 가질 수 있고 보온, 방음, 탈취, 항균, 살균, 유기화합물의 분해제거기능을 콘크리트구조체에 부여하게되나 특히 광촉매는 태양광의 에너지에 의하여 그 기능을 발휘하게 되므로 태양광이 투과하지 않는 콘크리트구조체의 내부에 분산되어있는 광촉매는 사실상 그 기능을 발휘할 수 없고 또한 표면층에 분산된 광촉매 역시 숯을 비롯한 다공성물질에 부착되어 있는 정도이여서 광촉매의 탈리 손실에 의한 기능저하 또한 고려하지 않을 수 없다.Korean Patent Publication (Registration No. 942990) discloses a description of the method for the production of a mortar for forming a concrete structure and its structure using porous porous particles, which are ultrafine photocatalyst micropowders in porous particles including charcoal particles. Method for manufacturing concrete mortar for forming a concrete structure using functional porous particles added to concrete mortar formed by cement and aggregate additive hydrosetting reaction by adjusting photocatalytic coated porous particles coated with As a related technology, the porous particles coated with photocatalyst fine powder are present in a uniformly dispersed state throughout the concrete mortar forming the concrete structure, so that the porous material and the photocatalyst can have the purpose of lightening, water purification and air purification. Soundproof, deodorization, antibacterial, sterilization, Decomposition and removal of organic compounds are given to concrete structures, but in particular, photocatalysts are exerted by the energy of sunlight, so photocatalysts dispersed in concrete structures that are not penetrated by sunlight cannot actually function. In addition, the photocatalyst dispersed in the surface layer is also attached to a porous material such as charcoal, so the deterioration due to the desorption loss of the photocatalyst is also to be considered.

이와 같이 광촉매를 콘크리트구조체에 적용함에 있어서 보다 효율적인 설계가 요구된다.As such, more efficient design is required in applying the photocatalyst to the concrete structure.

또한 국내등록번호 제935128호에는 "발수성과 대기정화기능을 가지는 하이드록시 아파타이트가 피복된 이산화티탄을 포함하는 광촉매 도료조성물"에 관한 기술내용을 소개하고 있다.In addition, Korean Patent No. 935128 introduces the technical content of "photocatalyst coating composition comprising titanium dioxide coated with hydroxyapatite having water repellency and atmospheric purification function".

이와 같은 광촉매 도료조성물을 콘크리트 2차 제품에 적용하기 위한 광촉매도료조성물로 구체적으로는 하이드록시 아파타이트가 피복된 이산화티탄 1~10중량%, 폴리실록산과 아크릴수지를 공중합하여 제조된 수성에멀젼 바인더 1~5중량%, 증점제 0.1~0.5중량%, 분산제 0.1~5중량%, 방부제 0.1~10중량% 및 물 85.5~97.7중량%로 구성되는 광촉매도료조성물로서 콘크리트표면에 수성에멀젼 바인더, 증점제, 분산제, 방부제 등의 유기화합물로 아파타이트가 피복된 광촉매를 코팅접착시키고 있다.A photocatalyst coating composition for applying such a photocatalyst coating composition to a concrete secondary product, specifically 1-10% by weight of titanium dioxide coated with hydroxyapatite, and an aqueous emulsion binder prepared by copolymerizing polysiloxane and acrylic resin. A photocatalyst paint composition consisting of weight percent, thickener 0.1 to 0.5 weight percent, dispersant 0.1 to 5 weight percent, preservative 0.1 to 10 weight percent, and water 85.5 to 97.7 weight percent, an aqueous emulsion binder, thickener, dispersant, preservative, etc. The photocatalyst coated with apatite with an organic compound is coated and bonded.

여기에서 광촉매는 빛 에너지에 의하여 유기화합물 자체를 분해시키는 기능을 보유하고 있으므로서 유기질 코팅층이 시간이 경화함에 따라 취약해질 수 있는 것으로 생각된다.It is thought that the photocatalyst has a function of decomposing the organic compound itself by light energy, and thus the organic coating layer may be vulnerable as time passes.

또한 콘크리트표면에 광촉매를 포함한 이질성의 합성수지의 코팅층이 형성되므로서 콘크리트 자체의 기공성에 의한 탈취성, 보수성 수분조절성의 기능 또한 장애를 받게 된다.In addition, since the coating layer of heterogeneous synthetic resin including a photocatalyst is formed on the concrete surface, the function of deodorizing and water-retaining moisture control due to the porosity of concrete itself is also impaired.

이상의 광촉매를 콘크리트제품에 적용한 종래기술들은 본원 출원자인 대명콘텍(주)에서 개발한 기술들로서 현재까지 생산해오면서 여러가지 문제점으로 나타난것을 지적하여 언급한 내용들이다.

상기 본 발명 콘크리트블록에 첨가되는 다공성 분말입자는 미세한 기공을 가지므로서 콘크리트블록을 경량화시킴과 동시에 방음성, 보온성, 탈취성, 항균성이 우수하고 일라이트 및 장호석분말 등은 우수한 원적외선 방사물질임과 동시에 탈취기능, 항균성을 동시에 갖고 있는 물질이며 전기석, 화산석분말은 음이온발생물질로 널리 알려져 있는 물질이다.The porous powder particles added to the concrete block of the present invention have fine pores, light weight concrete blocks, and sound insulation, thermal insulation, deodorization, and antimicrobial properties. Deodorizing and antimicrobial properties at the same time, tourmaline, volcanic stone powder is a material known as anion generating material.

또한 본 발명에서 광촉매라함은 TiO2 단결정 전극에 빛을 조사하면 물이 수소와 산소를 분해된다는 사실이 보고 되므로써 광촉매가 처음으로 발견되었다.In the present invention, the photocatalyst is the first photocatalyst was discovered by the fact that water decomposes hydrogen and oxygen when irradiated with TiO 2 single crystal electrode.

광촉매는 ZnO, Cds, WO3, SrTiO3, Cdse, KNbO3, TiO2 등과 같은 반도체성 산화물로서 밴드캡(Band gap) 에너지 이상의 빛을 받으면 가 전자대(valanceband) 전자가 전도대(conductionband)로 전이하여 전자(e-)와 정공(h+)을 생성하여 이들이 또다시 대기중의 O2 및 H2O 분자와 결합하여 강력한 유기물 분해능력을 가진 슈퍼옥사이드(O2 -)와 수산화이온(OH-)을 생성하고 이들의 촉매산화물중 이산화티타니움(TiO2)은 밴드캡 에너지대가 수소와 산소의 발생전위 영역에 걸쳐있어 물의 산화/환원반응이 동시에 가능하다. 이것은 광촉매의 두가지 오염물 분해물질인 슈퍼옥사이드와 수산화이온을 동시에 발생할 수 있는 것으로 산화반응 또는 환응반응 어느 한쪽만을 가능한 물질보다 광범위한 종류의 물질을 분해할 수 있다는 것을 의미하고 있다. 또한 TiO2는 화학적으로 안정하며 내약품성이 우수하고 무독성으로 인체에 무해하기 때문에 방어코팅 등에 널리 이용되고 있다하므로서 기능성의 면이나 안정성의 면에 있어 콘크리트블록에 적용하는 광촉매입자 또한 이산화티탄(TiO2)으로 조성된 코팅조성물을 콘크리트블록에 적용하기로 한다.Photocatalysts are semiconducting oxides such as ZnO, Cds, WO 3 , SrTiO 3 , Cdse, KNbO 3 , TiO 2, etc., and when they receive light above the band gap energy, the valence band electrons are transferred to the conduction band. To generate electrons (e-) and holes (h +), which in turn combine with O 2 and H 2 O molecules in the atmosphere to form superoxides (O 2- ) and hydroxide ions (OH-) that have strong organic decomposition Titanium dioxide (TiO 2 ) among these catalyst oxides has a band cap energy band over a generation potential region of hydrogen and oxygen, which enables the oxidation / reduction reaction of water simultaneously. This means that it is possible to simultaneously generate superoxide and hydroxide ions, two pollutant decomposers of photocatalysts, which can decompose a wider variety of materials than those capable of either oxidation or reaction reactions. In addition, since TiO 2 is chemically stable, has excellent chemical resistance, and is non-toxic and harmless to humans, photocatalytic particles applied to concrete blocks also have titanium dioxide (TiO 2) in terms of functionality and stability. The coating composition composed of) will be applied to the concrete block.

여기에서 콘크리트블록에 적용되는 광촉매입자로서 이산화티탄은 아나타제형의 이산화티탄 미세분말, 이산화티탄 광석인 예추석(아나타제석) 미세분말, 이산화티탄담지 숯분말, 이산화티탄 담지 퍼얼라이트, 이산화티탄 담지 질석분말, 아파타이트코팅 이산화티탄분말 형태로 콘크리트블록에 적용된다.Titanium dioxide as a photocatalyst particle applied to the concrete block is anatase-type titanium dioxide fine powder, titanium dioxide ore, anatase (fine anatase) fine powder, titanium dioxide-supported charcoal powder, titanium dioxide supported pearlite, titanium dioxide supported vermiculite It is applied to concrete blocks in the form of powder, apatite-coated titanium dioxide powder.

상기 광촉매입자로서 예추석은 티탄광석으로 화학성분이 TiO2로서 정방, 양추상, 단주, 판상의 결정계의 형태로서 담황 또는 갈색의 색상을 띠고 비중 3.82~3.97로 모아경도가 5.5~6으로 빛 에너지에 의해 강력한 유기물의 분해기능을 갖는 아나타제형 티탄광석으로 티탄철광인 일메나이트(ilmenite : (Fe,Mg) TiO3), 부루카이트형의 판티탄석, 루틸형의 티타니움광석인 금홍석(TiO2)과 같은 유기물분해기능이 없는 티탄광석과는 큰 차이가 있다.As the photocatalyst particles, anatase is a titanium ore, and its chemical composition is TiO 2 , which is light yellow or brown in the form of tetragonal, jujube, monolith, or plate-like crystal system. It is an anatase type titanium ore that has a strong decomposing function of organic matter, and it is ilmenite ((Fe, Mg) TiO 3 ) which is a titanium iron ore, and a titanium which is a brookite type and a rutile type titanium ore (TiO 2 ) There is a big difference from titanium ore without organic decomposition.

또한 숯, 퍼얼라이트, 질석분말 등의 다공성입자에 상기 광촉매입자를 담지시키는 방법은 아나타제형 이산화티탄 또는 이산화티탄광석(아나타제석)의 100mm이하인 입도 1~4wt%, 계면활성제(CTAB) 1~3wt%를 93~98%의 증류수에 첨가하여 호모계나이트로 40Mhz를 유지하면서 마쇄하고 이를 2시간 이상 상온에서 방치하여 분산액을 제조하고 이 분산액에 상기 다공성물질을 침지하여 탈수건조시키므로서 광촉매(이산화티타늄)가 담지된 다공성입자를 얻을 수 있다.In addition, the method of supporting the photocatalytic particles on porous particles such as charcoal, pearlite and vermiculite powder has a particle size of 1 to 4 wt% or less of 100 mm of anatase-type titanium dioxide or titanium dioxide ore (anata zeolite), and a surfactant (CTAB) 1 to 3 wt%. % Was added to 93-98% distilled water and ground at 40Mhz with homo-nitrite, which was left at room temperature for 2 hours or more to prepare a dispersion, and the photocatalyst (titanium dioxide) was dried by dipping and drying the porous material in this dispersion. ) Supported porous particles can be obtained.

그밖에 아파타이트코팅 이산화티탄에서 아파타이트는 분자식 Ca(PO4)5X2으로 나타낼수 있고 X로 표현되는 말단기에 따라 분류할 수 있으며 X가 하이드록시기(OH-)일 경우 하이드록시 아파타이트이고 X가 불소기(F-)일 경우 불화아파타이트이며 염소기일 경우 염화아파타이트가 된다.In apatite-coated titanium dioxide, apatite can be represented by the molecular formula Ca (PO 4 ) 5 X 2 and classified according to the terminal group represented by X. When X is a hydroxy group (OH-), it is hydroxy apatite and X is In the case of fluorine group (F-), it is apatite fluoride; in the case of chlorine group, it is apatite chloride.

상기 하이드록시 아파타이트는 인산성분을 함유하고 있고 그 자체가 OH기를 갖고 있어 수경화성을 가지고 있으며 또한 인산은 수산화티탄 이산화규소 등과도 결합하여 수경화성을 나타낸다 하므로서 아파타이트가 코팅된 이산화티탄 광촉매입자는 수화반응을 하면서 수경화성을 가지므로서 수경성조성물이 함유된 다른 물질 및 블록표면의 콘크리트조성물과 수경화반응으로 블록표면에 일체화된다.The hydroxyapatite contains a phosphoric acid component and itself has an OH group, which has hydrocurability. Also, the phosphoric acid is combined with titanium dioxide silicon dioxide and the like to exhibit hydrocurability. Thus, the titanium dioxide photocatalyst coated with apatite is hydrated. It is integrated with the surface of the block by the hydrocuring reaction with other materials containing the hydraulic composition and the concrete composition on the surface of the block.

여기에서 수경화반응에 유리한 아파타이트(Ca10(PO4)6X2)는 하이드록시기를 갖는 아파타이트(Ca10(PO4)6(OH2)로서 이를 선택 사용한다.Here, the apatite (Ca 10 (PO 4 ) 6 X 2 ), which is advantageous for the hydrocuring reaction, is selected and used as the apatite (Ca 10 (PO 4 ) 6 (OH 2 )) having a hydroxyl group.

또한 수경성조성물을 조성하는 조성물로서 광촉매입자는 상술한 내용과 같고 화산회(포졸란)는 시멘트 화학상 자체로는 경화하는 성질을 갖지 않으나 조성물에 첨가된 수산화칼슘 및 블록몸체에서 유리된 수산화칼슘과 서서히 화합해서 불용성의 수경성을 지닌 화합물을 생성하는 실리카 질성분을 주성분으로 갖는 물질이다.In addition, the photocatalyst particles are a composition for forming a hydraulic composition as described above, and volcanic ash (pozzolane) does not have a property of curing by cement chemical phase itself, but is gradually incompatible with calcium hydroxide added to the composition and calcium hydroxide liberated from the block body. It is a substance having a silica component as a main component to produce a compound having hydraulic properties.

마이크로 실리카는 마이크로 실리카의 단위사용량당 3~4배 시멘트를 대체할 수 있는 기능이 있으며 시멘트의 수화반응촉진제의 역활도하게되며 입자의 크기수가 수 ㎛이하의 구형입자이다.Micro-silica has the function of replacing 3 ~ 4 times cement per unit usage of micro-silica, and acts as a hydration accelerator of cement and is a spherical particle having a particle size of several μm or less.

시멘트 수화반응에서 포졸란반응은 수산화칼슘(Ca(OH)2)이 필요한데 마이크로 실리카가 없는 경우 수산화칼슘은 큰 덩어리로 존재하며 적은입자에 비교적 강하게 붙어있어 다음 단계로의 화학반응을 저해받게된다. 마이크로실리카가 함유되면 마이크로실리카가 이 수산화칼슘덩어리를 잘게 부수어 분산시키는 역활을하여 수산화칼슘이 포졸란반응에 좀더 활발하게 참여하게 하므로서 전체적인 시멘트 수화반응이 촉진되는 것이다.In the cement hydration reaction, the pozzolanic reaction requires calcium hydroxide (Ca (OH) 2 ). In the absence of micro-silica, calcium hydroxide is present in large chunks and is relatively strongly attached to small particles, which inhibits the chemical reaction to the next step. When microsilica is contained, the microsilica breaks down and disperses the lump of calcium hydroxide so that the calcium hydroxide becomes more active in the pozzolanic reaction, thereby promoting the overall cement hydration reaction.

그밖에 규산알카리는 수용액으로 무기질 결합제로 사용되고 있는 물질로서 원래 유리와 시멘트 경화제는 조성상, 구조상 관계가 깊다고 할 수 있고 규산알카리는 유리인 동시에 시멘트로서의 성질을 지니고 있다. 규산알카리는 대개의 경우 물유리의 형태로 이용되는데 이것은 건조에 의해서 규산이 중합하여 경화하게 되므로서 규산소다는 무기 및 유기물질과 조합하여 경화시킬 수 있으므로 볼록에 수경성 조성물들을 강력하게 경화시켜 결합시킬 수 있다.Alkali silicates are used as inorganic binders in aqueous solutions. Originally, glass and cement hardeners have deep structural and structural relationships. Alkali silicates are both glass and cement. Alkali silicate is usually used in the form of water glass, which is cured by drying the silicic acid, so that sodium silicate can be cured in combination with inorganic and organic materials, so that it is possible to harden and bond the hydraulic compositions to the convex. have.

그밖에 아미노기, 에폭시기, 이중결합의 관능기를 갖는 실란카프링제는 유기질재료와 무기질재료 또는 무기질재료와 무기질재료를 결합시키는 카프링제로서 결합강도를 현저하게 향상시킨다.In addition, the silane capping agent having an amino group, an epoxy group, or a double bond functional group is a capping agent that bonds an organic material and an inorganic material or an inorganic material and an inorganic material to significantly improve the bonding strength.

본 발명에서는 상술한 바와 같이 콘크리트블록의 전 몸체에 광촉매를 사용하지 않고 블록표면에만 사용하므로서 고가의 광촉매 사용량을 최소화하면서 광촉매의 효과를 최대로 도출할 수 있게 하고 또한 광촉매를 콘크리트와 이질적인 합성수지를 전색제로한 도료조성물로 콘크리트블록에 코팅하지 않고 콘크리트와 같은 동질의 수경화반응물질로 조성된 수경성조성액을 코팅하여 동질성의 콘크리트블록표면에 강력하게 결합경화시켜 일체화하므로서 콘크리트 몸체의 본래 기능으로서 기공성에 의한 탈취성, 보수성, 수분조절의 기능을 합성수지와 같은 이질적인 코팅막에 의해 장애받지않고 그대로 발휘할 수 있는 콘크리트블록을 제공함을 목적으로 하고 있다.In the present invention, by using only the surface of the block without using a photocatalyst on the entire body of the concrete block as described above, it is possible to derive the effect of the photocatalyst to the maximum while minimizing the use of expensive photocatalysts, and also as a photocatalyst to a concrete and a heterogeneous synthetic resin It is a paint composition that is coated with a hydraulic composition composed of homogeneous hydrocuring reaction materials such as concrete without coating on the concrete block, and is strongly bonded to the homogeneous concrete block surface to integrate it. The purpose of the present invention is to provide a concrete block that can exhibit deodorant, water retention, and moisture control functions without being hindered by heterogeneous coating film such as synthetic resin.

상기 본 발명에 따른 콘크리트블록의 실시예를들어 그 기능과 작용 등을 알아보기로 한다. For example, the function and action of the concrete block according to the present invention will be described.

상기 콘크리트조성에 따른 공시체중 B-1~B-3는 본 발명 콘크리트블록조성물의 범위 내에 속하는 공시체이고 공시체 B-4~B-6는 본 발명 콘크리트블록조성물의 범위를 벗어난 콘크리트조성물로서 통상적인 콘크리트조성물이라고도 할 수 있다.Specimens B-1 to B-3 according to the concrete composition are the specimens belonging to the range of the concrete block composition of the present invention and specimens B-4 to B-6 are the concrete compositions outside the range of the concrete block composition of the present invention. It may also be referred to as a composition.

상기 표(1)의 공시체에 사용된 굵은골재는 5~13mm범위에 균일하게 분포된 분쇄골재를 사용하고 잔골재는 0.1~5mm범위에서 균일하게 분포된 잔골재이고 다공성물질은 1mm~0.07mm크기의 숯입자를 사용하였으며 혼화제로서는 리그닌슬폰산염을 사용하였다.The coarse aggregate used in the specimens of Table (1) uses crushed aggregate uniformly distributed in the range of 5 ~ 13mm, fine aggregate is fine aggregate distributed uniformly in the range of 0.1 ~ 5mm and porous material is char of 1mm ~ 0.07mm size Particles were used, and lignin sulfonate was used as a admixture.

상기 표(1)의 공시체들의 압축강도를 알아보기 위하여 KSF 2405에 제시되어 있는 것과 같이 UTM을 이용하여 0.6±0.4MPa의 속력으로 압력을 가하면서 압축강도를 실험을 실시하였다. 그 결과 표(2)에서와 같이 공시체들의 압축강도 측정결과를 얻었다. 숯의 첨가량이 증가함에 따라 압축강도는 급격하게 감소함을 알 수 있고 숯을 첨가하지 않은 공시체 강도가 높은 것을 알 수 있다.In order to determine the compressive strength of the specimens of Table 1, the compressive strength was tested while applying pressure at a speed of 0.6 ± 0.4 MPa using UTM as shown in KSF 2405. As a result, the compressive strength of the specimens was obtained as shown in Table (2). It can be seen that the compressive strength decreases rapidly as the amount of charcoal is increased and the specimen strength without charcoal is high.

이와 같은 결과는 다공성의 구조를 갖고 있기 때문에 상대적으로 강도가 약한 숯이 압축강도를 낮게 하는 것으로 생각된다.This result is considered to be a relatively low strength charcoal lower the compressive strength because it has a porous structure.

상기 표(2)의 공시체(B-1)~(B-3)는 숯을 사용한 공시체의 압축강도는 다른 다공성물질로 콘크리트블록 조성범위 내에서 제작한 공시체에 비해서 숯이 가장 낮은 압축강도를 갖이며 그밖의 다공성물질은 같은 조건으로 첨가할 경우 숯의 압축강도에서 30% 증가한 범위 내에 속하고 있다.The specimens (B-1) to (B-3) of Table 2 have the lowest compressive strength of char as compared to the specimens produced within the range of concrete block composition with other porous materials. Other porous materials are in the range of 30% increase in the compressive strength of charcoal when added under the same conditions.

또한 상기 표(1)에 나타낸 공시체들이 물을 흡수하여 보관하는 량 즉, 보수성을 알아보기 위해서 물 흡수시험을 진행하였다. 물 흡수시험의 경우 28일간 양생한 한변이 5cm인 정육면체 공시체를 110±5℃온도를 유지한 상태에서 48시간 건조하여 무게를 측정하고 이를 48시간동안 수침한 다음 취출하여 마른 수건으로 표면을 닦은 다음 다시 무게를 측정하는 방식으로 진행하였다. 이와 같은 물 흡수율 시험결과를 표(3)에 나타내었다.In addition, the water absorption test was conducted to find out the amount of the specimens absorbed and stored in the table (1), that is, water retention. In the case of water absorption test, the cube specimen cured for 28 days was dried for 48 hours at 110 ± 5 ℃, weighed and soaked for 48 hours, then taken out and wiped with a dry towel. The weight was again measured. The water absorption test results are shown in Table (3).

상기 표(3)의 실험결과를 검토하면 다공성물질인 숯을 조성물로 첨가한 공시체 B-1~B-3는 숯을 첨가하지 않은 공시체 B-4~B-6보다 단위 중량당 물흡수율 즉, 보수성이 우수하고 또한 숯의 첨가량을 증가시킴에 따라 보수성(물 흡수율)이 급격하게 상승하게 된다.Examining the experimental results in the above Table (3), the specimens B-1 to B-3 to which the porous material charcoal was added as a composition had a water absorption rate per unit weight, that is, to the specimens B-4 to B-6 without charcoal. As the water retention is excellent and the amount of charcoal is increased, the water retention (water absorption rate) is rapidly increased.

그러나 본 발명 콘크리트조성물의 조성범위 이상으로 다공성물질을 사용하면 콘크리트강도를 취약하게 되어 강도에 문제점이 발생한다.However, when the porous material is used over the composition range of the concrete composition of the present invention, the strength of the concrete becomes weak, which causes problems in strength.

다음으로 공시체 B-1~B-4의 공시체로 수질정화성능을 평가하였다. 수질정화성능시험은 공시체를 잘게 분쇄한 입자를 이용하여 이중 100g을 취하여 400ml 삼각프라스에 넣고 조제한 오염수 150ml를 넣은 뒤 프라스크를 밀폐하고 20±1℃의 온도에서 항온조에 7일간 정치하였다.Next, the water purification performance of the specimens B-1 to B-4 was evaluated. For water purification performance test, 100g of the specimens were pulverized, put into 400ml Erlenmeyer Place, and 150ml of prepared contaminated water was put into the flask, and the flask was sealed and left in a thermostat at a temperature of 20 ± 1 ℃ for 7 days.

수질정화성능을 평가하기 위한 지표로 화학적산소요구량(COD), 총질소(T-N), 총인(T-P)를 측정하여 그 결과를 표(4)에 나타내었다.Chemical oxygen demand (COD), total nitrogen (T-N), and total phosphorus (T-P) were measured as indicators for evaluating water purification performance, and the results are shown in Table (4).

수질정화성능시험결과 공시체 (B-1)~(B-3)의 몸체 숯 첨가량 증가에 따라 COD, T-N, T-P 등의 감속폭이 증가하는 것을 알 수 있고 숯을 첨가하지 않는 공시체 B-4는 COD, T-N, T-P 등의 감속폭이 숯을 첨가한 공시체에 비해 작다.As a result of the water purification performance test, it was found that the deceleration range of COD, TN, TP, etc. increased as the body char was added in the specimens (B-1) to (B-3). Deceleration widths such as COD, TN, and TP are smaller than those of char-coated specimens.

그러나 본 발명 콘크리트몸체 조성물로된 공시체의 수질정화기능은 광촉매(TiO2)를 적용한 콘크리트조성물에 비해 크게 기대할 수 없다.However, the water purification function of the specimen of the present invention, the concrete body composition can not be expected significantly compared to the concrete composition to which the photocatalyst (TiO 2 ) is applied.

지금까지는 콘크리트몸체 조성물에 의한 공시체에 관한 여러가지 기능을 알아보았다.Up to now, various functions related to the specimen by the concrete body composition were examined.

다음은 본 발명 공시체 B-3에 본 발명 수경성반응물질로된 광촉매 분산 수경성조성물(액)을 코팅한 공시체 C-1과 공시체 B-3에 합성수지(아크릴수지)를 전색제로한 광촉매 분산조성물(액)을 코팅한 공시체 C-2를 비교하여 성능을 비교하였다.Next, the photocatalyst dispersion composition comprising the photocatalyst dispersion hydraulic composition (liquid) coated with the present invention hydraulic reactant on the specimen B-3 of the present invention and the synthetic resin (acrylic resin) on the specimen B-3 with the colorant (liquid) ) And the performance was compared by comparing the specimen C-2 coated.

여기에서 사용되는 광촉매입자는 10nm~200nm범위의 입자를 사용한다. 입자크기가 10nm이하인 경우에는 광촉매로서 빛을 흡수하는 수광능력이 떨어지고 200nm이상인 경우에는 분산성이 떨어지고 코팅후 탈리하는 경향이 생긴다.Photocatalyst particles used herein use particles in the range of 10 nm to 200 nm. If the particle size is less than 10nm, the light-receiving ability to absorb light as a photocatalyst is inferior. If the particle size is more than 200nm, dispersibility is inferior and there is a tendency to detach after coating.

상기 조성물 C1 및 C2를 각각 공시체 B-3에 0.5mm두께로 코팅하여 공시체 C-1, C-2를 제작하여 대기 및 수질정화기능을 알아보았다.The compositions C1 and C2 were coated with 0.5 mm thickness on specimen B-3 to prepare specimens C-1 and C-2, and the atmospheric and water purification functions were examined.

상기 표(5)의 수질정화실험결과 그리고 표(6) 및 표(7)와 실험결과 및 VOC 발생물질의 분해효과 실험결과는 공시체에 코팅된 광촉매의 기능에 의하여 얻어지는 효과로서 이와 같은 효과를 공시체 C-1과 C-2를 비교하건데 큰 차이가 없지만 양쪽 공히 수질정화 및 공기정화능력이 탁월하다 할 수 있다.The results of water purification of Table (5) and the results of Tables (6) and (7), and the results of decomposition and decomposition of VOC-generating materials, were obtained by the function of the photocatalyst coated on the specimens. Compared with C-1 and C-2, there is no big difference, but both have excellent water purification and air purification ability.

한편 표(8)에서와 같이 공시체의 탈취시험결과에서는 본 발명 콘크리트블록 몸체조성물로 성형된 블록몸체에 조성물 C1으로 코팅된 공시체 C-1은 코팅조성물 C2로 코팅된 공시체 C-2에 비하여 탈취효과가 현저하게 우수하다 할 수 있다.On the other hand, in the deodorization test results of the specimen as shown in Table (8), the specimen C-1 coated with the composition C1 on the block body formed of the concrete block body composition of the present invention has a deodorizing effect compared to the specimen C-2 coated with the coating composition C2. Can be remarkably excellent.

공시체 C-1과 공시체 C-2가 동일한 몸체조성임에도 불구하고 상기와 같은 탈취기능의 효과차이가 발생하는 것은 코팅조성물 C1과 C2의 차이에서 기인된다고 할 수 있다.Although specimen C-1 and specimen C-2 have the same body composition, the effect difference of the deodorizing function may be attributed to the difference between the coating compositions C1 and C2.

흡착에 의한 탈취기능 공시체 C-1 및 C-2의 내부몸체를 구성하는 다공성물질에 의하여 발휘된다고 볼 수 있는데 상기와 같은 기능차이는 공시체 C-2의 표면에 있는 코팅조성물층이 합성수지(아크릴수지)를 전색제로 하는 도막층으로 되어 있어 공시체 C-2의 몸체 미세기공의 공기통로가 장애를 받기 때문에 탈취기능이 떨어진다고 볼 수 있다.Deodorization function by adsorption can be said to be exhibited by the porous material constituting the inner body of the specimens C-1 and C-2. The functional difference as described above is that the coating composition layer on the surface of the specimen C-2 is a synthetic resin (acrylic resin). ), And the deodorizing function is deteriorated because the air passage of the body micropores of specimen C-2 is impaired due to the coating layer using the colorant.

이상과 같이 본 발명의 콘크리트블록은 광촉매 사용량을 최소화하면서 광촉매의 효과를 최대로 발휘할 수 있게 하므로서 우수한 수질정화 및 대기정화작용을 가지고 광촉매 코팅층이 몸체와 동질성의 수경화성 조성물로 구성되어 있어 블록몸체의 기능을 제대로 발휘하게 하므로서 탈취성, 보수성, 방음성, 보온성, 항균성, 원적외선 방사기능 등 다기능성을 가지는 대기 및 수질정화작용을 갖는 기능성 콘크리트블록으로 스프릿블록, 식생호안블록, 식생옹벽블록, 법면블록, 보도블록으로 널리 사용할 수 있는 기능성 콘크리트블록이라 할 수 있다.As described above, the concrete block of the present invention has the excellent water purification and atmospheric purification while minimizing the amount of photocatalyst, and the photocatalyst coating layer is composed of the body and the homogeneous hydrocurable composition. It is a functional concrete block with air and water purification function that has various functions such as deodorization, water retention, sound insulation, heat insulation, antibacterial, far infrared radiation function by showing the function properly. It is a functional concrete block that can be widely used as a sidewalk block.
