Description
본 발명은 폴리머 차수재 및 이의 제조방법에 관한 것으로서, 상세하게는 폴리머 차수재에 가교제, 첨가제 및 유화제를 혼합하여 팽윤성 및 반응속도가 개선된 저수지 복통의 누수 보수용 폴리머 차수재 및 이의 제조 방법에 관한 것이다.The present invention relates to a polymer barrier material and a method for manufacturing the same, and more specifically, to a polymer barrier material for repairing water leaks in a reservoir stomach with improved swelling properties and reaction rates by mixing a polymer barrier material with a crosslinker, additive, and emulsifier, and to a method for manufacturing the same. It's about.
복통은 일반적으로 저수지에서 취수시설의 하나로 방류부(도수부)에 해당되며, 저류수를 제체 하류로 도수하기 위하여 제체 내부를 횡단하여 설치하는 시설이고, 취수터널은 제체와 분리시켜 인접된 산을 관통하여 설치하는 시설이다.Botong is generally one of the water intake facilities in a reservoir and corresponds to the discharge part (discharge part). It is a facility installed across the inside of the reservoir to deliver stored water to the downstream of the reservoir, and the water intake tunnel is separated from the reservoir and connects the adjacent mountain. It is a facility installed through a penetrating device.
농업용 저수지는 취수터널 형식도 있으나, 일반적으로 복통 형식으로 설치하는 경우가 많으며, 단면의 규모도 대체로 크지 않은 편이다. 그러므로 복통의 규모는 작은 구경의 단면인 관체(콘크리트관, 흄관, 철관 등)를 철근콘크리트로 감싸는 구조로 되어 있으며 제고가 높거나 규모가 큰 저수지에서는 콘크리트 라이닝 구조(말굽형, 원형, 반원형, 박스형 등)로 되어 있다.Agricultural reservoirs can take the form of water intake tunnels, but they are generally installed in the form of a double tube, and the cross-sectional size is generally not large. Therefore, the size of the barrel is a structure that surrounds a small-diameter cross-sectional pipe (concrete pipe, Hume pipe, iron pipe, etc.) with reinforced concrete, and in reservoirs with high elevation or large size, a concrete lining structure (horseshoe-shaped, circular, semi-circular, box-shaped) is used. etc.).
농업용 저수지는 약 100일간의 관개기간동안 경지에 관개용수를 공급하다가 비관개기인 동절기에는 혹한에 노출됨으로써 관개기 동안 콘크리트 조직내부 공극으로 스며든 물이 동절기에 동결하는 현상(동해)이 발생하여 동결압에 의한 콘크리트 균열발생 등 성능저하 현상이 나타난다.Agricultural reservoirs supply irrigation water to farmland for an irrigation period of about 100 days, but are exposed to extreme cold during the non-irrigation winter season, causing water that seeps into the pores within the concrete structure during the irrigation period to freeze in the winter (frost damage). Performance deterioration phenomena such as cracks in concrete due to pressure appear.
이러한 복통의 결함 사항은 콘크리트의 열화현상에 의하여 누수, 균열, 박리, 박락, 백태, 철근부식, 축제재료인 점토 유출현상이 나타나며, 손상부위는 도 1에 도시된 바와 같이 시공이음부에서 많이 발생하고 있고, 시공이음부의 손상으로 인해 누수가 발생한다.These abdominal pain defects occur due to the deterioration of concrete, such as water leakage, cracks, peeling, delamination, whitening, corrosion of reinforcing bars, and leakage of clay, which is a construction material, and the damaged area often occurs at the construction joint as shown in Figure 1. Water leaks occur due to damage to construction joints.
이러한 시공이음부에서 발생하는 누수 현상을 보수하기 위해, 아크릴 지수재 등을 시공이음부에 주입하는 방법이 많이 이용되고 있으나, 아크릴 수지재는 0.3mm 이하의 미세공극에서 최대의 성능을 발휘하기 때문에 사용에 제한이 있다. 그리고 누수에 의해 아크릴 지수재가 유실될 수 있기 때문에, 차수 성능이 반감되고 반복적으로 아크릴 지수재를 재시공해야 하는 단점이 있다.In order to repair water leakage that occurs at such construction joints, the method of injecting acrylic water-stopping material, etc. into the construction joint is widely used. However, acrylic resin material is used because it exhibits maximum performance in micropores of 0.3 mm or less. There is a limit to And because the acrylic water stopper can be lost due to water leakage, there is a disadvantage in that the waterproofing performance is halved and the acrylic water stopper must be repeatedly reinstalled.
이러한 문제점을 해결하기 위하여, 본 출원인에 의해 국내 등록특허 제10-1920120호인 폴리머 차수재 및 폴리머 차수재를 이용하는 콘크리트 댐 구조물의 누수 보수 방법이 개발되었다.In order to solve this problem, the present applicant has developed a polymer barrier material and a water leakage repair method for a concrete dam structure using a polymer barrier material, which is Korean Patent No. 10-1920120.
상기 폴리머 차수재는 단량체인 아크릴아마이드, 가교제인 PEGDA 및 개시제인 APS를 포함하며, 상기 가교제의 몰수와, 상기 단량체 및 상기 가교제의 몰수 합의 비율은 1 내지 2%이며, 상기 단량체 및 상기 가교제의 질량 합과, 상기 단량체, 가교제 및 개시제가 수용액에 용해된 용액의 질량의 비율은 25 내지 35%이며, 상기 개시제의 몰수는 수학식 1과 같다.The polymer barrier material includes acrylamide as a monomer, PEGDA as a cross-linking agent, and APS as an initiator, and the ratio of the number of moles of the cross-linking agent to the sum of the number of moles of the monomer and the cross-linking agent is 1 to 2%, and the sum of the masses of the monomer and the cross-linking agent And, the mass ratio of the monomer, cross-linking agent, and initiator dissolved in the aqueous solution is 25 to 35%, and the number of moles of the initiator is as shown in Equation 1.
그러나, 폴리머 차수재는 50㎜ 이하의 이음부 사이로 친수성 차수재를 백업제로 쓰여지기 때문에 누수 발생시 팽윤성이 높아야 하고, 갑작스런 누수 발생에 대응하기 위하여 초기반응 속도가 빨라야 하는 데, 이러한 종래의 폴리머 차수재는 습윤상태일 때 115~132% 정도 부피가 증가되고, 실험결과 완전 습윤상태에서 50시간 경과시 부피비가 165%, 120%, 도달까지 걸리는 시간은 약 200분으로 초기 부피 증가 속도가 느려 누수 발생에 대응이 쉽지 않는 문제점이 있다.However, because polymer barrier materials are used as a backup agent for hydrophilic barrier materials between joints of 50 mm or less, they must have high swelling properties when water leaks occur and must have a fast initial reaction speed to respond to sudden water leaks. When in normal condition, the volume increases by about 115-132%, and as a result of the experiment, after 50 hours in a fully wet state, the volume ratio increases to 165% and 120%, and the time it takes to reach is about 200 minutes, so the initial volume increase rate is slow, responding to water leaks. There is a problem that is not easy to solve.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 폴리머 차수재에 가교제, 첨가제 및 유화제를 혼합하여 팽윤성 및 반응속도가 개선된 저수지 복통의 누수 보수용 폴리머 차수재 및 이의 제조 방법을 제공하는데 그 목적이 있다.The present invention is intended to solve the above problems, and the purpose of the present invention is to provide a polymer water barrier material for repairing water leaks in a reservoir tank with improved swelling properties and reaction rates by mixing a crosslinker, additive, and emulsifier in the polymer water barrier material, and a method for manufacturing the same. There is.

하기에서 본 발명을 설명함에 있어, 관련된 공지 기능 또는 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명은 생략할 것이다. 그리고 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로서 이는 사용자, 운용자의 의도 또는 관례 등에 따라 달라질 수 있다. 그러므로 그 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. The terms described below are defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definition should be made based on the contents throughout this specification.

본 발명에 따른 저수지 복통의 누수 보수용 폴리머 차수재는 수용액인 물 10~80중량%, 단량체인 아크릴아마이드(acrylamide) 5~45중량%, 유화제인 EG(Ethylene glycol) 5~45중량%, 가교제인 MBAA(N-Methylenebisacrylamide) 0.2~1.0중량%, 첨가제인 MMA(Methylmethacrylate) 0.5~2.0중량%, 개시제인 APS(Ammonium persulfate) 0.5~2.0중량%로 혼합된다.The polymer barrier material for repairing water leaks in the reservoir stomach according to the present invention consists of 10 to 80% by weight of water as an aqueous solution, 5 to 45% by weight of acrylamide as a monomer, 5 to 45% by weight of EG (Ethylene glycol) as an emulsifier, and 5 to 45% by weight as a crosslinking agent. It is mixed with 0.2~1.0% by weight of MBAA (N-Methylenebisacrylamide), 0.5~2.0% by weight of MMA (Methylmethacrylate) as an additive, and 0.5~2.0% by weight of APS (Ammonium persulfate) as an initiator.
