Description
본 발명은 수처리 시설 바닥재용 항균성 폴리우레아 조성물 및 이를 이용한 방수방식공법에 관한 것으로, 특히, 수처리에 따라 세균번식력 및 오염성이 높은 수처리 시설의 바닥에 폴리우레아 방수도막층을 형성함으로써, 방수도막의 접착성, 방수성, 흡착성이 보장되도록 하여 장기간 사용에도 방수성능을 확보할 수 있게 함은 물론, 방수도막층에 포함된 자체적인 항균력에 의해 세균번식의 억제시키고, 소독효과가 극대화될 수 있도록 하여 청결하게 시설을 관리 및 사용할 수 있게 하는 수처리 시설 바닥재용 항균성 폴리우레아 조성물 및 이를 이용한 방수방식공법에 관한 것이다.The present invention relates to an antibacterial polyurea composition for flooring in a water treatment facility and a waterproofing method using the same. It ensures waterproof performance even after long-term use by ensuring waterproofness, water-resistance, and adsorption properties. It relates to an antibacterial polyurea composition for flooring in a water treatment facility that enables management and use of the facility, and a waterproofing method using the same.
일반적으로 사무용 건물, 아파트 및 공공건물 등 대부분의 주거용 및 상업용 건물에는 물을 공급하기 위한 물탱크 뿐만 아니라 주방, 화장실, 주차장, 세차장, 도축장 등 물을 이용하는 각종 수처리 시설이 설치되어 있다.In general, in most residential and commercial buildings such as office buildings, apartments, and public buildings, various water treatment facilities using water such as kitchens, toilets, parking lots, car washes and slaughterhouses are installed as well as water tanks for supplying water.
상기한 수처리 시설 다습하고 어두워 균이 번식하기에 좋은 조건을 갖추고 있어 대장균을 포함하는 균에 의해 바닥 뿐만 아니라 물도 오염되는 문제가 있었다.The above-mentioned water treatment facility is humid and dark, and it has good conditions for the propagation of bacteria, so there is a problem that not only the floor but also the water is contaminated by bacteria including E. coli.
한편, 수처리 시설의 바닥에는 방수도료 또는 방수재를 시공하여 도막을 형성하는 방수방식공법도 제시되는 바, 이때, 수처리 시설의 특성 상 바닥의 방수도막층에는 물이 자주 접하게 되므로 오염물에 노출되기 쉽고, 특히, 다습조건에 의하여 세균번식에 따라 열악한 환경조성이 우려되며, 내수성이 우수하고, 내부 표면 등에서 도막으로 스며드는 수분에 기인하는 습윤 조건에서도 내부의 표면에 접착성을 유지할 필요가 있다.On the other hand, a waterproofing method of forming a coating film by installing a waterproofing paint or waterproofing material on the floor of a water treatment facility is also proposed. In particular, it is necessary to maintain the adhesiveness to the inner surface even under wet conditions due to moisture, which is caused by moisture permeating into the coating film from the inner surface, etc.
따라서, 수처리 시설에 사용될 경우 물과의 오랜 접촉을 통한 세균번식의 우려가 있어 도막에 자체적인 항균력이 부여되도록 하여 수처리 시설이 청결한 상태를 유지할 수 있도록 하는 대안이 절실히 요구되는 실정이다.Therefore, when used in a water treatment facility, there is a risk of bacterial propagation through prolonged contact with water, so an alternative that allows the water treatment facility to maintain a clean state by giving the coating film its own antibacterial power is urgently required.
즉, 수처리 시설의 바닥이 오염될 경우, 수처리 시설에서 사용 및 가공되는 물품 등이 오염될 수도 있으며, 오염된 바닥면이 물과 함께 외부로 유출될 경우 환경 문제를 야기할 수 있으므로, 단순한 방수 기능 뿐만 아니라 수처리 시설의 바닥면에도 항균력 및 소독력을 증강시켜 청결한 상태를 유지시킬 필요가 있다.In other words, if the floor of the water treatment facility is contaminated, items used and processed in the water treatment facility may be contaminated, and if the contaminated floor surface is leaked out with water, it may cause environmental problems. In addition, it is necessary to maintain a clean state by enhancing antibacterial and disinfecting power on the floor surface of the water treatment facility.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 방수재료 조성물이 가지는 문제점을 극복하고 항균기능을 실질적으로 이용할 수 있는 새로운 방수재료 조성물을 제공하되, 수처리 시설의 바닥에 방수도료에 의한 방수도막층이 형성될 경우 방수도막층 자체적으로 세균번식력을 억제하는 항균효과와 소독효과가 발생할 수 있도록 하여 수처리 시설 이용 시 항상 청결한 상태가 유지될 수 있게 하고, 내, 외부 오염물로부터 바닥이 오염되지 않게 하는 수처리 시설 바닥재용 항균성 폴리우레아 조성물 및 이를 이용한 방수방식공법을 제공하는데 그 목적이 있다.The present invention has been devised to solve the above problems, and provides a new waterproofing material composition that can overcome the problems of the waterproofing material composition and substantially use the antibacterial function, but a waterproofing coating film made of a waterproofing paint on the floor of a water treatment facility When a layer is formed, the waterproof coating layer itself has an antibacterial and disinfecting effect that inhibits the growth of bacteria, so that a clean condition can be always maintained when using a water treatment facility, and the floor is not polluted from internal and external contaminants. An object of the present invention is to provide an antibacterial polyurea composition for flooring in a water treatment facility and a waterproofing method using the same.

도 1은 본 발명에 따른 수처리 시설 바닥재용 항균성 폴리우레아 조성물 및 이를 이용한 방수방식공법의 플로우챠트.1 is a flowchart of an antibacterial polyurea composition for flooring in a water treatment facility according to the present invention and a waterproofing method using the same.
본 발명 수처리 시설 바닥재용 항균성 폴리우레아 조성물은, 1차혼합물과 2차혼합물이 5:5 ~ 7:3의 부피비로 혼합되어 이루어진다.The antimicrobial polyurea composition for flooring in a water treatment facility of the present invention is made by mixing a primary mixture and a secondary mixture in a volume ratio of 5:5 to 7:3.
상기 본 발명 수처리 시설 바닥재용 항균성 폴리우레아 조성물 중 1차혼합물은 트리에틸포스핀 20 ~ 35 중량%와, 1,2-디브로모헥산 5 ~ 22 중량%와, 폴리에테르 폴리올에테르 폴리올의 반응에 의해 제조된 이소시아네이트 말단 프리폴리머 20 ~ 40 중량%와, 아민가 90 ~ 130 이고, 당량이 130 ~ 190인 이소포론디아민 15 ~ 30 중량%와, N-메틸모르포린 5 ~ 15 중량%와, 3,3-디메틸-4,4-디아미노-디사이클로헥실메탄 8 ~ 25 중량%와, 폴리옥시에틸렌 라우릴에테르 2 ~ 10 중량%와, 선형 저밀도 폴리에틸렌(LLDPE Linear Low Density Polyethylene) 2 ~ 10 중량%와, 폴리아이소뷰틸렌(Polyisobutylene) 5 ~ 10 중량%%로 조성된다.The first mixture of the antimicrobial polyurea composition for flooring in a water treatment facility of the present invention is 20 to 35% by weight of triethylphosphine, 5 to 22% by weight of 1,2-dibromohexane, and polyether polyol ether polyol. 20-40 wt% of isocyanate-terminated prepolymer prepared by -Dimethyl-4,4-diamino-dicyclohexylmethane 8-25 wt%, polyoxyethylene lauryl ether 2-10 wt%, and LLDPE Linear Low Density Polyethylene (LLDPE Linear Low Density Polyethylene) 2-10 wt% , polyisobutylene (Polyisobutylene) is composed of 5 to 10% by weight.
본 발명 수처리 시설 바닥재용 항균성 폴리우레아 조성물의 1차혼합물 중 트리에틸포스핀은, 조성물들과의 반응 시간을 결정하고 흡착 기능을 제공하는 물질로서, 1차혼합물 100중량%를 기준으로 20 ~ 35 중량%가 첨가되는데, 상기 35 중량%를 초과하는 경우에는 조성물들의 반응속도가 너무 빨라지게 되어 교반성 및 시공성이 저하되고, 20 중량% 미만 첨가 시 조성물들의 반응속도가 너무 느려지게 되어 작업 시간이 증가하게 되는 문제점이 있으므로, 상기한 한정 범위를 유지하는 것이 바람직하다.Triethylphosphine in the primary mixture of the antimicrobial polyurea composition for flooring in a water treatment facility of the present invention is a substance that determines the reaction time with the compositions and provides an adsorption function, and is 20 to 35 based on 100% by weight of the primary mixture When the weight % is added, when it exceeds 35% by weight, the reaction rate of the compositions becomes too fast, and the stirrability and workability are lowered, and when less than 20% by weight is added, the reaction rate of the compositions becomes too slow and the working time Since there is a problem that increases, it is preferable to maintain the above-described limited range.
본 발명 수처리 시설 바닥재용 항균성 폴리우레아 조성물의 1차혼합물 중 1,2-디브로모헥산은 조성물들의 점도를 조절하여 교반효율이 향상되도록 하는 물질로서, 1차혼합물 100중량%를 기준으로 5 ~ 22 중량%가 첨가되는데, 상기 한정된 범위를 벗어나는 경우 조성물의 전반적인 점도와 혼합율 등 물리적 특성이 저하되므로 상기한 바와 같이 한정된 범위의 임계적 의의를 가지는 것이 바람직하다.1,2-dibromohexane among the primary mixtures of the antimicrobial polyurea composition for flooring in water treatment facilities of the present invention is a material that improves the stirring efficiency by controlling the viscosity of the compositions, and is 5 ~ based on 100% by weight of the primary mixture 22 wt% is added, and if it is outside the limited range, physical properties such as overall viscosity and mixing rate of the composition are lowered, so it is preferable to have the critical significance of the limited range as described above.
