본 발명은 액상 은나노를 사용한 항균성 지하저수조 코팅재 조성물에 관한 것이다.The present invention relates to an antimicrobial underground reservoir coating composition using liquid silver nano.
최근 정수장에서 생산된 물이 가정으로 공급되는 과정에서 2차오염문제가 제기되어 수돗물의 수질관리 대상이 취수원, 정수장에서 배수관, 급수관, 저수조 등으로 이전되어 이들 시설의 관리에 대한 중요성이 부각되고 있다. Recently, the secondary pollution problem has been raised in the process of supplying the water produced in the water purification plant to the home, and the water quality management object of the tap water has been transferred from the intake source, the water purification plant to the drainage pipe, the water supply pipe, the reservoir, and the importance of management of these facilities is highlighted. .
특히, 아파트의 지하저수조는 수돗물이 전달되는 과정에 가장 큰 문제점을 갖고 있는 대상으로 거론되고 있으나 현재까지 해결방안이 충분히 검토되지 않은 상황이다. 즉, 공동주택의 지하저수조는 비상시에 대비한 예비수량을 확보하고, 수돗물을 안정적으로 공급하기 위하여 설치되어 왔으나, 최근 구조 및 재질불량, 청소 및 관리소홀 등으로 수돗물의 수질을 떨어뜨려 시민들의 불신을 가중시키는 요인이 되고 있다. 이러한 건축물내 기존 저수조는 미생물 재성장의 가능성이 크고, 그 외 내식성이 높은 재질의 확보부족, 상부의 염소가스에 의한 부식, 저수조 하부에 유입되는 이물질 및 내부 방수재 탈리, 강재의 부식에 의한 녹물 발생 등의 문제가 대두되고 있다. In particular, the underground reservoirs of apartments have been mentioned as having the biggest problem in the process of delivering tap water, but the solutions have not been fully studied until now. In other words, underground water tanks of multi-unit houses have been installed to secure the reserve quantity for emergency and to supply the tap water stably, but recently, the quality of tap water has been degraded due to poor structure and materials, cleaning and management neglect. It is becoming a factor to add weight. Existing water tanks in these buildings have a high possibility of microbial regrowth, lack of high corrosion resistance material, corrosion by chlorine gas in the upper part, debris from the water tank and desorption of internal waterproofing material, and generation of rust due to steel corrosion. 'S problem is on the rise.
따라서 아파트의 지하저수조는 음료용 수조로 물의 유입과 유출을 막는 방수 기능 이외에도 유해물질의 용출 및 미생물의 성장을 억제하는 위생기능도 충족해야 한다.Therefore, the underground reservoir tank of the apartment must meet the hygiene function to suppress the elution of harmful substances and the growth of microorganisms in addition to the waterproof function to prevent the inflow and outflow of water into the beverage tank.
하지만 현재 지하저수조에 적용되고 있는 방수 또는 코팅재료가 대부분 유기계 재료를 사용하고 있어 모체와의 부착력은 높으나 통기성이 없어 계면의 탈락 현상이 심하고, 콘크리트와 열팽창계수가 2배이상 차이가 있어 모체의 거동에 순응하지 못해 내구성이 짧다는 단점과, 시멘트의 미수화물이 물에 용출되는 사례가 있다는 단점과, 미수화물의 용출로 인한 pH가 높아져 수질을 좋지 않다는 단점과, 외부 환경조건 변화에 따른 안정성이 부족하며, 2차 오염물질을 발생하는 등 음용수를 관리하는데 많은 문제점이 있다.However, most of the waterproofing or coating materials applied to underground reservoirs use organic materials, and the adhesion to the mother is high, but because of the air permeability, there are severe dropouts at the interface, and the behavior of the mother is different because the coefficient of thermal expansion differs more than twice. The disadvantage of short durability due to incompatibility, the disadvantage that the unhydrated cement is eluted in water, the poor quality of water due to the high pH due to the elution of unhydrated, and the stability according to the change of external environmental conditions Insufficient, there are many problems in managing drinking water, such as generating secondary pollutants.
상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 시공자의 작업안전을 위해 시공시 인체에 무해한 무독성 소재를 적용하고, 음용수로서의 안전성을 높이기 위해 미생물의 증식을 억제하고자 항균성 세라믹 소재를 사용하고, 또한 지하저수조의 환경을 고려하여 시공성, 내구성, 통기성, 내수성, 방수성, 수용성, 환경보호성, 그리고 습윤조건 및 내알카리상태에서 콘크리트와의 부착력을 개선한 지하저수조용 코팅재 조성물을 제공하는데 있다.The object of the present invention for solving the above problems is to apply a non-toxic material harmless to the human body during construction for the safety of the construction of the installer, and to use the antimicrobial ceramic material to suppress the growth of microorganisms to increase the safety as drinking water, In consideration of the environment of the underground reservoir, it is to provide a coating material composition for the underground reservoir to improve the construction, durability, breathability, water resistance, waterproof, water solubility, environmental protection, and adhesion to the concrete in the wet conditions and alkali resistance.
상기와 같은 본 발명의 목적은 물과 시멘트의 수화반응과 폴리머와 기능성 세라믹의 표면효과를 폴리아크릴릭에스테르계에멀젼, 물, 은용액, 백시멘트, 메타카올린, CSA, 경질탄산칼슘, 규사로 구성되어 조성된 코팅재조성물을 제공함으로써 달성된다.The object of the present invention as described above is composed of polyacrylic ester emulsion, water, silver solution, back cement, metakaolin, CSA, hard calcium carbonate, silica sand It is achieved by providing a formulated coating composition.
상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명의 실시예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings, the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the task for eliminating the conventional drawbacks.
본 발명은 코팅재 조성물은 액성분인 폴리아크릴릭에스테르계에멀젼, 물, 은용액과, 분말성분인 백시멘트, 메타카올린, CSA, 경질탄산칼슘, 규사로 구성되어 물과 시멘트의 수화반응과 폴리머와 기능성 세라믹의 표면효과를 가진 코팅재로 방수기능은 물론 미생물 성작을 억제하는 항균기능을 갖고 있어 수질을 안정적으로 관리할 수 있으며, 또한 코팅재의 수밀성이 높아 구체를 보호하며, 통기성능을 갖고 있어 장시간 경과하여도 들뜸이나 박리 등의 결함이 발생되지 않도록 구성하였다.In the present invention, the coating composition is composed of polyacrylic ester emulsion, water, silver solution, powder, white cement, metakaolin, CSA, hard calcium carbonate, silica sand, and hydration reaction of water and cement, and polymer and functional properties. This coating material has a surface effect of ceramic, and it has a waterproof function and an antibacterial function that suppresses microbial growth, so that the water quality can be managed stably, and the watertightness of the coating material protects the sphere, and it has a breathing performance. In addition, it was comprised so that defects, such as lifting and peeling, may not generate | occur | produce.
본 발명 코팅재조성물의 구성 메카니즘을 설명하면 다음과 같다.Referring to the configuration mechanism of the coating material composition of the present invention.
(가)방수메카니즘(A) Waterproofing mechanism
도 1은 기존 방수구조와 본 발명의 방수구조를 대비한 개념도이다.1 is a conceptual view in contrast to the existing waterproof structure and the waterproof structure of the present invention.
지하저수조의 코팅은 수돗물을 오염시키지 않는 위생기능과, 저장한 수돗물이 누수되거나 지하수가 유입되지 않는 방수기능이 요구된다. The coating of the underground reservoir requires hygienic functions that do not contaminate the tap water, and a waterproof function that prevents leakage of stored tap water or inflow of underground water.
수돗물이 오염되지 않기 위해서는 미생물이 성장하지 않고, 부유물질이 용출되지 않는 재료로 구성되어야 하며, 또한, 방수재로서 견고한 막을 형성하기 위해서는 모체와 접착성, 내수성, 투수성을 갖고 있으면서 모체의 습기를 통과시키는 통기성을 갖고 있어야 장기적인 내구성을 확보할 수 있다. In order not to be contaminated with tap water, it must be composed of a material which does not grow microorganisms and does not elute suspended solids. Also, to form a strong membrane as a waterproofing material, it has to pass through the mother's moisture while having adhesiveness, water resistance, and permeability to the mother body. It must be breathable to ensure long-term durability.
따라서 본 발명에서는 물과 염소의 침투는 차단하면서 구체의 습기는 통과하는 코팅막을 제조하고, 수질보존을 위해 미생물 성장을 억제하고 오염물질을 방출하지 않는 기능성소재를 첨가한 환경친화적 도막시스템을 구성하였다. 또한, 시공자가 작업하는 과정에 독성의 악취로 인한 피해를 줄이기 위해 기존 용제형 소재를 수계 에멀젼으로 대체하였다. 하지만 기존의 수계 에멀젼은 용제계보다 접착력이 상당히 감소되는 특성이 있으므로 본 발명에서는 에폭시를 공중합하여 접착력을 증진하였다.Therefore, in the present invention, a coating film is prepared in which water and chlorine penetrates, while moisture passes through the sphere, and an eco-friendly coating film system is added to suppress the growth of microorganisms and to release pollutants for water conservation. . In addition, in order to reduce the damage caused by the toxic odor during the work of the contractor, the existing solvent-type material was replaced with an aqueous emulsion. However, since the conventional aqueous emulsion has a property of significantly reducing the adhesive strength than the solvent system, in the present invention, the adhesive strength is enhanced by copolymerizing epoxy.
(나)항균메카니즘(B) Antibacterial mechanism
항균메카니즘은 도 2와 같이 크게 두가지로 구분할 수 있다. The antimicrobial mechanism can be largely divided into two as shown in FIG.
용출형 항균메카니즘은 항균특성을 나타내는 금속이온의 직접적인 용출에 의해 항균특성을 나타낸다. Ag, Au, Pt, Cu, Zn 등의 전이금속계 이온들은 항균효과를 가진 것으로 확인된 바 있는데 이중 Ag이온은 다른 전이금속계 이온들에 비해 더욱 탁월한 항균효과를 발현한다. 특히, Feng 등의 연구결과에 따르면 Ag이온의 경우 Ag가 cell내부의 DNA에 영향을 끼쳐 복제능력을 떨어뜨리고 Cell을 비활성화 시키기 때문이라고 보고하였다. 이러한 용출형 항균소자는 세균과 직접적인 접촉에 의하여 우수한 항균효과를 나타내게 된다.The dissolution antibacterial mechanism exhibits antimicrobial properties by direct dissolution of metal ions exhibiting antimicrobial properties. Transition metal ions such as Ag, Au, Pt, Cu, Zn have been found to have an antimicrobial effect. Of these, Ag ions exhibit more excellent antimicrobial effects than other transition metal ions. In particular, according to the results of Feng et al. Ag ions reported that Ag affects the DNA inside the cell, reducing the replication ability and inactivating the cell. Such an eluted antimicrobial device exhibits an excellent antimicrobial effect by direct contact with bacteria.
비용출형 항균 메카니즘은 광촉매(photocatalytic) 효과의 일종으로써 빛의 복사에 의해 활성산소(·O2-) 및 OH 라디칼(·OH)이 발생하게 된다. The non-release antibacterial mechanism is a kind of photocatalytic effect, and free radicals (· O 2− ) and OH radicals (· OH) are generated by light radiation.
이들은 항균작용을 주도하는 중요한 기구가 되며, OH라디칼 보다는 활성산소에 의한 항균력이 더 우수하다는 결과가 보고되고 있다. These are important mechanisms leading to the antimicrobial action, the results are reported that the antimicrobial activity is more excellent by the active oxygen than OH radicals.
Ag이온 등과 같은 용출형 항균소자는 균을 죽이되 cell을 남겨두는 형태지만 광촉매 효과는 균의 사멸과 동시에 cell까지도 분해하는 장점이 있다. 또한, 대장균은 소멸될 때 endotoxin을 방출하는데 이 물질은 이차적으로 체내에서 고열 등의 질환을 유발하게 된다. 하지만 이러한 광촉매 시스템은 toxin계 물질도 분해하므로 부작용을 예방할 수 있다.Elution-type antimicrobial devices such as Ag ions kill bacteria but leave cells, but the photocatalytic effect has the advantage of killing bacteria and decomposing cells. In addition, E. coli releases endotoxin when it dies, which in turn causes diseases such as high fever in the body. However, these photocatalyst systems also decompose toxin-based substances, thus preventing side effects.
하지만 상기 광촉매는 자외선 조사장치가 별도로 필요하여 장치구성이 복잡하다는 문제점이 있어 본 발명에서는 Ag이온을 사용한 용출형 항균메카니즘을 사용한다.However, since the photocatalyst requires a separate ultraviolet irradiation device, there is a problem in that the device configuration is complicated. In the present invention, an eluting antimicrobial mechanism using Ag ions is used.
(다) 유해물질 비용출 메카니즘(C) Hazardous Substance Emission Mechanisms
기존 유무기 복합형 재료의 경우 도 3과 같이 시멘트의 미수화물이 물에 용출되는 사례가 있으나 본 발명은 폴리머가 결합하기 이전에 메타카올린이 시멘트 수화율을 높여 미수화물이 용출되는 원인을 최소화하도록 구성하였다. 또한, 미수화물의 감소로 인한 재료의 pH가 낮아져 수질을 안정적으로 관리할 수 있는 구조이다. In the case of the existing organic-inorganic composite material, as shown in FIG. 3, the unhydrated cement is eluted in water, but the present invention minimizes the cause of the unhydrated metakaolin by increasing the cement hydration rate before the polymer is bonded. Configured. In addition, the pH of the material due to the reduction of the unhydrated structure is able to stably manage the water quality.
도 4는 본 발명 폴리머와 세라믹의 접착반응을 보인 개념도, 도 5는 본 발명 폴리머와 세라믹의 결합반응을 보인 개념도, 도 6은 본 발명 폴리머와 시멘트 페이스트의 계면구조도인데, 이를 참조하여 본 발명 코팅재 조성물인 시멘트 수화물과 기능성 세라믹 그리고 폴리머간의 접착, 결합, 계면구조의 반응구조를 살펴본다.4 is a conceptual diagram showing the adhesion reaction of the polymer and the ceramic of the present invention, FIG. 5 is a conceptual diagram showing the bonding reaction of the polymer and the ceramic of the present invention, and FIG. 6 is an interface structure diagram of the polymer and cement paste of the present invention. The reaction structure of adhesion, bonding and interfacial structure between cement hydrate, functional ceramic and polymer as a composition is examined.
시멘트와 기능성세라믹의 수화과정에 시멘트 겔이 형성되고 수화하는 동안 수산화칼슘이 생성되어 물에 존재한다. 반면, 폴리머 입자는 시멘트겔과 수화되지 않은 시멘트 입자의 혼합물에 퇴적된다. Cement gels are formed during the hydration of cements and functional ceramics, and calcium hydroxide is formed and is present in the water during hydration. Polymer particles, on the other hand, are deposited on a mixture of cement gel and unhydrated cement particles.
시멘트의 수화가 진행되고 모세관수가 줄어듦으로서 폴리머 입자는 시멘트겔과 수화되지 않은 시멘트입자의 혼합물 표면에 응집되어 연속적이고 밀실한 폴리머 입자층을 형성하며, 동시에 혼합물에 존재하는 커다란 공극속에 크기가 더 작은 폴리머 입자가 채워진다.As the hydration of the cement progresses and the capillary number decreases, the polymer particles aggregate onto the surface of the mixture of cement gel and unhydrated cement particles to form a continuous, tight polymer particle layer, while at the same time the smaller polymer in the large voids present in the mixture. Particles are filled.
반응성 폴리머 입자 표면과 Ca2+이온, 수산화칼슘 입자표면 혹은 고재의 실리카 층 사이에서 화학적 반응이 일어나며, 이러한 반응은 시멘트 수화물과 골재의 접착력을 증진시키고 굳은 폴리머시멘트 모르터나 콘크리트의 특성을 증가시킨다.Chemical reactions occur between reactive polymer particle surfaces and Ca 2+ ions, calcium hydroxide particle surfaces, or solid silica layers, which enhance the adhesion between cement hydrates and aggregates and increase the properties of hard polymer cement mortar or concrete.
궁극적으로 시멘트 수화에 의해 공극수가 소모되어 짐에 따라 시멘트 수화물 표면의 밀실한 폴리머 입자는 연속적인 막 또는 띠로 합체되고 시멘트 수화물에 침투해 네트워크를 형성시켜 시멘트 수화물을 결합시킨다. 골재는 굳은 모르터 혹은 콘크리트가 될 때까지 그러한 구조의 매트릭스에 갇혀 있게 된다.Ultimately, as the pore water is consumed by cement hydration, the dense polymer particles on the surface of the cement hydrate coalesce into a continuous film or band, penetrate the cement hydrate to form a network to bond the cement hydrate. Aggregates are trapped in the matrix of such structures until they become hard mortar or concrete.

이하 본 발명을 구성하는 각 구성원소의 특징을 보다 구체적으로 설명한다.Hereinafter, the features of each member constituting the present invention will be described in more detail.
(1)폴리아크릴릭 에스테르계 에멀젼(1) polyacrylic ester emulsions
본 발명에 사용한 에멀젼 수지는 지하저수조용으로 별도 개발한 폴리아크릴릭 에스테르계 에멀젼으로 아래의 [화학식 1]로 표현되고, 그 물리적 특성은 아래의 표2와 같다. 폴리아크릴릭 에스테르계 에멀젼은 시멘트와 혼화성이 좋은 장점이 있다.Emulsion resin used in the present invention is a polyacrylic ester-based emulsion developed separately for the underground water reservoir represented by the following [Formula 1], the physical properties are shown in Table 2 below. Polyacrylic ester emulsion has the advantage of good compatibility with cement.
시멘트와 혼합할 경우 발생되는 반응 메카니즘은 크게 두가지로 분류할 수 있는데, 첫째 물과 건조한 시멘트 입자간의 수화반응과, 둘째 아크릴과 시멘트 표면과의 반응으로 나눌 수 있다. The reaction mechanisms generated by mixing with cement can be classified into two types: first, hydration reaction between water and dry cement particles, and second reaction between acrylic and cement surface.
물과 시멘트입자의 결합으로 발생되는 수화반응을 방해하지 않고 서서히 경화되면서 가사시간을 늘리고, 완전히 수화된 CSH입자의 표면을 아크릴(Acryl)막으로 둘러싼다. 그리고 아크릴과 젤(Gel)화되지 않은 Ca(OH)2와의 화학결합으로 안정화되는 구조를 갖고 있다. The curing time is gradually increased without disturbing the hydration reaction caused by the combination of water and cement particles, and the surface of the fully hydrated CSH particles is surrounded by an acrylic film. And it has a structure that is stabilized by a chemical bond between acryl and ungelled Ca (OH) 2 .

상기 식에서, n은 50 내지 10,000이고, 상기 R은 CH3, CH2CH3, CH2CH3 로 이루어진 군중에서 선택된 어느 하나이다.
상기에서 n 값을 50 내지 10000으로 한정한 이유는 실제 반응시 50보다 작거나 10000보다 큰 중합이 일어날 수 있지만 상기와 같은 중합도일 경우에 상기 화학식에 따른 전체 분자량이 5000 내지 1,000,000이 되고, 이와 같은 분자량일 때가 안정적이기 때문이다.
Wherein n is 50 to 10,000, and R is any one selected from the group consisting of CH 3 , CH 2 CH 3 , and CH 2 CH 3 .
The reason for limiting the value of n to 50 to 10000 is that the polymerization may occur less than 50 or more than 10000 during the actual reaction, but in the case of the polymerization degree as described above, the total molecular weight according to the above formula is 5000 to 1,000,000 This is because the molecular weight is stable.
지하저수조 코팅용으로 개발한 폴리머는 아크릴계 모노머를 주성분으로 하고 접착력을 증진하기 위해 에폭시를 도입하여 공중합체한 것으로, 아크릴수지는 화학구조적으로 내열성(-40～204℃), 고온에서의 내유성, 내산성, 내용제성(특히 Aliphatic hydrocarbons), UV저항성 등의 장점을 갖고 있다. The polymer developed for the coating of underground reservoir is made of acrylic monomer as the main component and copolymerized by introducing epoxy to enhance adhesion. Acrylic resin is chemically structurally heat resistant (-40 ~ 204 ℃), oil resistance and acid resistance at high temperature. It has advantages such as solvent resistance (especially aliphatic hydrocarbons) and UV resistance.

First, it is a copolymer composed of MMA (Methyl methacrylate), which has surface hardness and strength enhancement function, Butyl acrylate (BA), which has flexibility and elasticity, and AA (Acrylic acid), which has hydrophilicity and cement hydrate. Same as 10-12.

(2) 메타카올린(Metakaolin)(2) Metakaolin
본 발명에 사용된 메타카올린은 기능성 세라믹으로 항균성분을 갖는 소재와 물의 pH를 안정적으로 조절하는 성분을 가지는데, 메타카올린(Metakaolin)은 포졸 란(화산회)으로 코팅재에 사용된 시멘트의 물성을 개선하는데 사용되며 그 특성을 설명하면 다음과 같다.The metakaolin used in the present invention is a functional ceramic having an antimicrobial component and a component for stably adjusting the pH of water.Metakaolin is a pozzolan (volcanic ash) to improve the properties of the cement used in the coating material. It is used to explain the characteristics as follows.
포틀랜드 시멘트가 물과 결합하여 수화반응이 진행되면 다음 식과 같이 칼슘실리케이트하이드레이트(CSH)와 칼슘하이드록사이드(CH)의 두가지 물질을 형성한다.When Portland cement is combined with water to undergo a hydration reaction, two materials, calcium silicate hydrate (CSH) and calcium hydroxide (CH), are formed.
상기 식 중 칼슘실리케이트하이드레이트는 시멘트 성질의 화합물로 콘크리트의 강도를 증진시키고 성능을 발휘하고, 칼슘하이드록사이드는 시멘트 수화반응의 역부산물로 풍해, 공극의 증가, 알칼리실리카반응, 콘크리트의 노후화를 촉진시켜 강도나 기타 물성에 큰 도움을 주지 않는다. In the above formula, calcium silicate hydrate is a cement compound, which enhances the strength and exerts the performance of the concrete. Calcium hydroxide is the reverse by-product of the cement hydration reaction, increasing the porosity, alkali silica reaction, and promoting the aging of concrete. It does not help strength or other physical properties.
또한 칼슘하이드록사이드는 물에 용출되어 수질을 오염시키며, 용출된 부위는 공극이 되어 코팅재의 내구성을 저해한다. 또한, 실리카와 반응하여 젤을 형성하는 알칼리실리카반응을 일으키는데 젤은 수분속에서 인장응력이 작용하여 칼슘실리케이트하이드레이트의 결합조직을 파괴한다.In addition, calcium hydroxide is eluted in water to contaminate the water quality, and the eluted site becomes voids to inhibit the durability of the coating material. In addition, an alkali silica reaction, which reacts with silica to form a gel, causes a tensile stress in the water to destroy the connective tissue of calcium silicate hydrate.
그러나 본 발명에 사용된 메타카올린은 미수화된 칼슘하이드록사이드를 칼슘실리케이트하이드레이트로 변화시켜 시멘트의 강도 밀도, 내구성을 강화시켜 준다.However, metakaolin used in the present invention converts the unhydrated calcium hydroxide into calcium silicate hydrate to enhance the strength density and durability of the cement.
즉, 풍해를 저감시키고, 알칼리실리카반응을 억제하며, 공극을 감소시켜 수 밀성을 증진시켜 준다. That is, it reduces wind damage, suppresses alkali silica reaction, and improves water tightness by reducing voids.
또한, 지하저수조가 수돗물과 장기간 접하게 될 경우 염소이온(클로라이드)이 침투하여 콘크리트를 중성화시키고, 철근의 부식을 가속시키게 되는 문제가 있으나 본 발명의 메타키올린은 이러한 염소의 투과성능을 줄여 내구성능을 높여주게 된다.In addition, when the underground reservoir is in contact with tap water for a long time, chlorine ion (chloride) penetrates to neutralize concrete and accelerates corrosion of reinforcing steel, but the metachiolin of the present invention reduces the permeability of chlorine to increase durability. Will increase.
------메타카올린에 의한 수화반응식------ Hydration Reaction Formula with Metakaolin
포졸란 반응을 일으키는 플라이애쉬, 실리카흄, 고로슬래그 등의 산업부산물은 반응성, 색상 등 품질의 일관성이 없어 저수조 코팅재를 형성하는데 필요한 품질에 적합하지 않은 부분이 있다. 또한, 검은색이거나 흰색을 띠고 있어 색상의 연출이 제한된다는 문제점이 있으나, 본 발명 메카카올린은 명도(Whiteness : 백색 100, 흑색 0)가 90이상으로 색상의 연출이 우수하다. Industrial by-products such as fly ash, silica fume, and blast furnace slag, which cause pozzolanic reactions, are inconsistent in quality such as reactivity and color, and thus are not suitable for the quality required to form a reservoir coating. In addition, the black or white has a problem that the production of the color is limited, but the present invention mekaolin has excellent brightness of the color (whiteness: white 100, black 0) is more than 90.
저수조 코팅재에 메타카올린을 사용하여 얻어지는 효과는 수화반응이 일정하게 진행되므로 색상의 얼룩이 덜하고 일정한 색상을 가능하게 하며, 미수화물의 양이 감소되므로 저수조내 물의 탁도가 낮아지는 효과가 있다. The effect obtained by using metakaolin in the reservoir coating material is a hydration reaction proceeds uniformly so that less color unevenness and a constant color, and because the amount of unhydrated is reduced there is an effect that the turbidity of the water in the reservoir is lowered.
또한, 입자의 크기가 시멘트입자의 보다 작아 무기세라믹의 수밀성을 높여 방수성능이 강화되고 유해물질의 유입을 차단하는 효과가 강화되는 장점이 있다.In addition, the particle size is smaller than that of the cement particles to increase the watertightness of the inorganic ceramic has the advantage that the waterproofing performance is enhanced and the effect of blocking the introduction of harmful substances.
(3) 은용액(3) silver solution
본 발명에 사용된 은나노입자는 크기가 약 0.0015~0.015μm이며, 농도가 약 10,000ppm의 고농도로 제작한 제품을 사용하였다. Silver nanoparticles used in the present invention is about 0.0015 ~ 0.015μm in size, was used as a product produced in a high concentration of about 10,000ppm concentration.
입자가 작고 농도가 높은 제품은 일반 제품에 비해 넓은 표면적을 형성하므로 병균을 살균하는 효과가 뛰어나다. 이는 천연 항생제로서 바이러스, 박테리아, 곰팡이, 세균 등의 세포 속으로 쉽게 침투하여 호흡할 때 필요한 효소의 기능을 정지시켜 질식시킴으로서 이들을 죽게 하는 특성이 있다. 또한, 일반 항생제의 경우 그 기능이 5∼6종류에 국한되는 데에 반해 은나노입자는 박테리아, 곰팡이균 등은 물론 일반 항생제가 전혀 작용을 하지 않는 바이러스를 포함하여 약 650 여종의 각종 병원체에 대하여 효과가 있는 것으로 보고 되고 있다.Smaller particles and higher concentration products have a larger surface area than ordinary products, which is effective in sterilizing germs. It is a natural antibiotic that can easily penetrate into cells such as viruses, bacteria, fungi, bacteria, etc., and kills them by suffocating by stopping the function of enzymes required when breathing. In addition, in the case of general antibiotics, the function is limited to 5 to 6 types, whereas silver nanoparticles are effective against about 650 kinds of pathogens including bacteria, fungi, etc. as well as viruses in which the general antibiotics do not work at all. It is reported that there is.

본 발명 조성물의 미생물 성장억제성능을 확인하기 위하여 은을 첨가한 코팅재와 첨가하지 않은 코팅재를 유리시편에 도포하여 미생물 재성장 특성을 비교하였다. In order to confirm the microbial growth inhibitory performance of the composition of the present invention, a coating material without silver and a coating material without addition were applied to glass specimens to compare microbial regrowth characteristics.
기존의 배합비를 동일하게 적용한 대조군과 비교한 결과 기능성 소재를 첨가한 시료의 미생물 성장성은 극히 미미했으나, 항균소재를 첨가하지 않은 대조군의 부착미생물량은 기하급수적으로 증가하는 것으로 나타났다.(도 9참조)Compared with the control group to which the same compounding ratio was applied, the microbial growth of the sample containing the functional material was extremely insignificant, but the amount of adherent microorganisms of the control group without the antimicrobial material increased exponentially (see FIG. 9). )
본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
상기와 같은 본 발명은 물과 시멘트의 수화반응과 폴리머와 기능성 세라믹의 표면효과를 가진 코팅재로 방수기능은 물론 미생물 성작을 억제하는 항균기능을 갖고 있어 수질을 안정적으로 관리할 수 있으며, 또한 코팅재의 수밀성이 높아 구체 를 보호하며, 통기성능을 갖고 있어 장시간 경과하여도 들뜸이나 박리 등의 결함이 발생되지 않는 장점을 갖는다. 즉, 지하저수조 및 옥내배관에 코팅시 부착강도가 좋고 pH가 높지 않고 안정적이며, 미생물증식성이 극히 미미하다는 장점을 가져 지하저수조 및 옥내배관의 코팅재로 적합하고, 인체에 무해한 에멀젼과 기능성 세라믹을 사용하여 시공시 안전하며, 자극성 소재가 없어 작업환경이 개선되고, 유해물질의 용출이 없어 위생적이라는 장점을 가진 유용한 발명으로 산업상 그 이용이 크게 기대되는 발명이다.
