Abstract

The present invention relates to a crack repair primer for a concrete structure and a crack repair method for a concrete structure using the primer. The crack repair primer contains: 75 to 85 parts by weight of an epoxy resin containing a hardener and a prepolymer in which epichlorohydrin and bisphenol A are mixed; 10 to 20 parts by weight of a diluent selected from a glycidyl-based reactive diluent and a phthalate-based non-reactive diluent; and 5 to 15 parts by weight of an adhesive reinforcing agent containing butyl acrylate, calcium carbonate, and polypropylene wax. According to the present invention, the primer is capable of serving as a concrete structure crack filler and a painting film base layer, and thus crack repair construction preparation and execution can be simplified. In addition, a step of filling a crack with the primer and an application step are divided so that it is possible to prevent fluidity attributable to partial hardening of the primer in the crack.

Description

콘크리트 구조물의 균열 보수용 프라이머 및 이를 이용한 균열 보수 공법{CRACK REPAIR PRIMER OF BUILDING STRUCTURE AND CRACK REPAIR METHOD FOR CONCRETE STRUCTURE USING THEREFOR}A primer for repairing cracks in concrete structures and a crack repair method using the same {CRACK REPAIR PRIMER OF BUILDING STRUCTURE AND CRACK REPAIR METHOD FOR CONCRETE STRUCTURE USING THEREFOR}

본 발명은 콘크리트 구조물의 균열 보수용 프라이머 및 이를 이용한 콘크리트 구조물의 균열 보수 공법에 관한 것으로서, 보다 상세하게 설명하면 콘크리트 기반의 건축 또는 토목 구조물의 외관 및 내부 등에 균열이 발생하였을 때 용이한 충진 및 경화 과정으로 효과적으로 균열을 보수할 수 있고, 프라이머 상에 균열 부위를 보호할 수 있는 보호층을 적층할 수 있는, 콘크리트 구조물의 균열 보수용 프라이머 및 이를 이용한 콘크리트 구조물의 균열 보수 공법에 관한 것이다.The present invention relates to a primer for repairing cracks in a concrete structure and a method for repairing cracks in a concrete structure using the same.In more detail, when a crack occurs in the exterior and interior of a concrete-based building or civil structure, it is easy to fill and harden. The present invention relates to a primer for repairing cracks in concrete structures, and a method for repairing cracks in concrete structures using the same, which can effectively repair cracks through the process and laminate a protective layer that can protect cracks on the primer.

건축 공법 또는 토목 공법으로 건설된 구조물의 균열은 지진, 태풍 등의 자연 재해의 영향이나 시공의 결함, 노후화 등으로 발생하게 된다. 이때, 균열을 방치할 시 하중, 진동이 강도가 약한 균열 부위에 집중되어 균열이 확대될 수 있는 문제와 균열 부위로 수분 및 산소가 스며들어 알칼리성을 유지해야 하는 콘크리트의 pH를 낮추게 되는 문제가 따른다.Cracks in structures constructed using the building method or civil engineering method are caused by natural disasters such as earthquakes and typhoons, defects in construction, and deterioration. At this time, when the crack is left unattended, there is a problem in that the load and vibration are concentrated in the crack area with weak strength, so that the crack may expand, and moisture and oxygen permeate into the crack area to lower the pH of the concrete, which must maintain alkalinity. .

이러한 균열을 보수하기 위해 균열을 메꾸는 물질을 균열 부위 내에 충진시키는 퍼티 공법이 적용되고 있는바, 기존의 퍼티 공법은 균열 충진용 퍼티와 상층 형성용 프라이머를 별도로 구비하여 준비 과정이 복잡해지기 때문에 다양한 경력을 보유하고 숙련된 시공자가 요구된다.In order to repair such cracks, a putty method is applied in which the material that fills the crack is filled into the crack area.The existing putty method has a separate putty for crack filling and a primer for upper layer formation, which complicates the preparation process. Experienced and skilled contractors are required.

도 1은 본 발명의 프라이머의 기본적인 구성을 도시한 개념도이다.1 is a conceptual diagram showing the basic configuration of the primer of the present invention.

우선, 본 발명의 프라이머는 콘크리트 구조물에 적용되는 것을 기본으로 하는바, 콘크리트 구조물이라 함은 콘크리트를 베이스로 한 구조물, 예를 들어 토목현장 교량 및 터널과 같은 토목 구조물을 비롯하여 빌딩, 주거지, 건물, 조형물을 의미한다. 본 발명의 프라이머는 이러한 콘크리트 구조물의 내외부 벽면, 기둥 내지 보, 바닥면 등과 같은 세부 부위에 적용될 수 있다.First, the primer of the present invention is applied to a concrete structure as a basis, and the concrete structure refers to a structure based on concrete, for example, a civil engineering structure such as a bridge and a tunnel at a civil engineering site, as well as a building, a residential area, a building, It means a sculpture. The primer of the present invention may be applied to detailed areas such as inner and outer walls, columns to beams, and floor surfaces of such a concrete structure.

도 1을 보아 알 수 있듯이, 본 발명의 프라이머(1)는 에폭시 수지(10), 희석제(20), 접착성 보강제(30)를 포함한다.As can be seen from FIG. 1, the primer (1) of the present invention includes an epoxy resin (10), a diluent (20), and an adhesive reinforcing agent (30).

에폭시 수지(10)는 본 발명의 프라이머(1)의 기본적인 물성을 제공하는 물질로서, 에폭시 수지(10)의 물성은 잘 알려진 바와 같이 우수한 가공성, 내수성, 접착성 등을 보유하는바, 이러한 에폭시 수지(10)는 프리폴리머(11) 및 경화제(12)의 2액 형으로 구성됨으로써 콘크리트 구조물의 균열 보수 시공 시점에 맞추어 혼합하는 것이 가능하다.Epoxy resin 10 is a material that provides the basic physical properties of the primer 1 of the present invention, and the physical properties of the epoxy resin 10 have excellent processability, water resistance, adhesion, etc., as is well known, such an epoxy resin. Since (10) is composed of a two-component type of prepolymer 11 and hardener 12, it is possible to mix according to the time of repair and construction of cracks in concrete structures.

프리폴리머(11)는 저장 및 사용이 용이한 액상 단계에서 고분자의 중합을 멈춘 상태로서, 에피클로로하이드린(Epichlorohydrin)과 BPA(BisphenolA)의 혼합물이다.The prepolymer 11 is a mixture of epichlorohydrin and BPA (BisphenolA) in a state in which polymerization of the polymer is stopped in the liquid phase, which is easy to store and use.

즉, 본 발명의 프리폴리머(11)는 비스페놀A 형 에폭시의 프리폴리머(11)일 수 있는바, 비스페놀A 형 에폭시는 특히 접착성이 뛰어남은 물론이고 경화 과정에서 부피 변화가 없는 것은 물론 휘발성 물질이 발생하지 않을 뿐 아니라 사용법 및 주의점 등이 잘 알려져 있다는 이유로 숙련도가 높지 않은 시공자도 사용할 수 있는 특징이 있다.That is, the prepolymer 11 of the present invention may be a prepolymer 11 of a bisphenol A type epoxy, and the bisphenol A type epoxy has particularly excellent adhesion and does not change in volume during the curing process, as well as generating volatile substances. Not only does it not do it, it has a feature that can be used even by contractors with low skill levels because the usage and precautions are well known.

경화제(12)는 프리폴리머(11)를 열경화성 수지로 개질하는 것으로서, 80 내지 130℃의 폭 넓은 작업 온도를 설정할 수 있는 아민계 경화제(12)인 것이 가능한데 예를 들어, 폴리아마이드, 폴리아미도아마이드, 아미노트리아진 노볼락, 이소포론디아민 등의 아민계 경화제(12) 중 하나 이상이 선택될 수 있다. The curing agent 12 is a modification of the prepolymer 11 with a thermosetting resin, and may be an amine curing agent 12 capable of setting a wide working temperature of 80 to 130°C. For example, polyamide, polyamidoamide, One or more of the amine-based curing agents 12 such as aminotriazine novolac and isophoronediamine may be selected.

다시 말해, 에폭시 수지(10)는 프리폴리머(11)를 경화제(12)로 개질한 비스페놀A 형 에폭시 수지(10)로서 경화제(12)를 통한 시공성 및 석재, 목재, 유리 등의 다양한 환경에 적용 가능한 접착성을 제공한다.In other words, the epoxy resin 10 is a bisphenol A type epoxy resin 10 modified from a prepolymer 11 with a curing agent 12, and can be applied to various environments such as stone, wood, glass, and workability through the curing agent 12. Provides adhesion.

희석제(20)는 경화되기 이전의 본 발명의 프라이머(1)를 희석해 점도를 낮추는 것으로서, 반응성 희석제(21) 또는 비반응성 희석제(22) 중 하나가 선택되는 것이 가능하다.The diluent 20 decreases the viscosity by diluting the primer 1 of the present invention before curing, and one of the reactive diluent 21 or the non-reactive diluent 22 may be selected.

반응성 희석제(21)는 상술한 프리폴리머(11)와의 반응성을 보유한 희석제(20)로서 글리시딜 계열의 물질일 수 있는바, 예를 들어 BGE(Butyl glycidyl ether), PGE(Phenyl glycidyl ether), TCDE(tert-Carboxylic Diglycidyl ether) 등 일 수 있다.The reactive diluent 21 is a diluent 20 having reactivity with the prepolymer 11 described above, and may be a glycidyl-based material, for example, BGE (Butyl glycidyl ether), PGE (Phenyl glycidyl ether), TCDE. (tert-Carboxylic Diglycidyl ether) and the like.

이러한 반응성 희석제(21)는 프라이머(1)의 점도를 균일하게 조절할 수 있으나, 프로폴리머와 과량이 반응할 경우 프라이머(1)의 내마모성 및 전기적 성질이 저하될 수 있다. The reactive diluent 21 may uniformly adjust the viscosity of the primer 1, but when reacting with the propolymer in an excessive amount, the abrasion resistance and electrical properties of the primer 1 may be deteriorated.

비반응성 희석제(22)는 프로폴리머와 반응하지 않고 점도를 조절하는 것이 가능한 프탈레이트 계열의 물질일 수 있는바, 예를 들어 DBP(Dibutyl phthalate), DOP(Dioctyl phthalate) 등일 수 있다.The non-reactive diluent 22 may be a phthalate-based material capable of adjusting the viscosity without reacting with the propolymer, and may be, for example, dibutyl phthalate (DBP), dioctyl phthalate (DOP), or the like.

이러한 비반응성 희석제(22)는 프라이머(1)의 물성을 직접적으로 저하시키지 않으므로 혼합 비율에 따라 용이하게 점도를 조절할 수 있으나, 과량 사용될 경우 경화된 프라이머(1)의 표면에 일부 석출되어 접착성을 저하시킬 수 있다.Since the non-reactive diluent 22 does not directly degrade the physical properties of the primer 1, the viscosity can be easily adjusted according to the mixing ratio. However, when used in excess, it partially precipitates on the surface of the cured primer 1, resulting in adhesion. You can lower it.

다시 말해, 본 발명의 희석제(20)는 시공 환경에 따라 반응성 희석제(21) 또는 비반응성 희석제(22) 중 하나가 선택될 수 있는바, 도막의 기초 층에 적용되는 프라이머(1)의 특성상 내마모성 및 전기적 성질이 우선시 되지는 않으므로 일반적인 시공 환경에서는 반응성 희석제(21)를 적용하는 것이 바람직하다.In other words, as the diluent 20 of the present invention, one of the reactive diluent 21 or the non-reactive diluent 22 may be selected depending on the construction environment. And since electrical properties are not prioritized, it is preferable to apply the reactive diluent 21 in a general construction environment.

이러한 희석제(20)는 상술하였듯이 프라이머(1)의 점도를 낮출 수 있는바, 점도가 낮아진 프라이머(1)는 콘크리트 구조물의 균열에 충진되기 용이하여 균열 보수에 특화되는 것이 가능하다.As described above, the diluent 20 can lower the viscosity of the primer 1, and the primer 1 with a lower viscosity is easily filled into the cracks of the concrete structure, and thus it is possible to specialize in repairing cracks.

접착성 보강제(30)는 본 발명의 프라이머(1)의 접착성을 증진시키는 것으로서, 접착성 보강제(30)를 통해 접착성이 증진된 본 발명의 프라이머(1)는 균열의 보수하는 공지의 퍼티 역할은 물론이고, 콘크리트 구조물의 균열 부위를 보호할 수 있는 층을 추가로 적층하기 용이하여 프라이머(1) 고유의 의미에 따른 역할 또한 수행할 수 있다.The adhesive reinforcing agent 30 is to improve the adhesion of the primer 1 of the present invention, and the primer 1 of the present invention, which has improved adhesiveness through the adhesive reinforcing agent 30, is a known putty that repairs cracks. In addition to the role, it is easy to additionally laminate a layer that can protect the cracked portion of the concrete structure, so that the primer 1 can also play a role according to the meaning of the primer (1).

이러한 기능을 제공하는 접착성 보강제(30)는 부틸아크릴레이트(Butyl acrylate) 및 탄산칼슘 및 PP Wax(Polypropylene wax)를 포함하여 제조될 수 있는바, 구체적인 제조 방법은 후술하도록 한다.The adhesive reinforcing agent 30 providing such a function may be prepared including butyl acrylate, calcium carbonate, and PP Wax (polypropylene wax), and a specific method of manufacturing it will be described later.

정리하면, 본 발명의 프라이머(1)는 에폭시 수지(10) 75 내지 85 중량부, 희석제(20) 10 내지 20 중량부, 접착성 보강제(30) 5 내지 15 중량부를 혼합하여 균열 부위에 충진 및 도포되는 것이 가능하다.In summary, the primer (1) of the present invention is mixed with an epoxy resin (10) 75 to 85 parts by weight, a diluent (20) 10 to 20 parts by weight, and an adhesive reinforcing agent (30) 5 to 15 parts by weight to fill the crack area and It is possible to be applied.

이때, 희석제(20)의 비율이 과하게 높아지면 접착 성능이 저하될 수 있고, 접착성 보강제(30)의 비율이 과하게 높아지면 본 발명의 프라이머(1)의 점도가 높아져 콘크리트 구조물의 균열 부위에 가득 충진되기 어려운 개연성이 따를 수 있는바, 상술한 바와 같은 적절한 혼합 비율을 유지하는 것이 바람직하다.At this time, if the ratio of the diluent 20 is excessively high, the adhesion performance may be deteriorated, and if the ratio of the adhesive reinforcing agent 30 is excessively high, the viscosity of the primer 1 of the present invention increases and fills the cracks of the concrete structure. Since there may be a possibility that it is difficult to fill, it is desirable to maintain an appropriate mixing ratio as described above.

이러한 혼합 비율로 혼합된 본 발명의 프라이머(1)는 균열 부위를 메우는 공지의 퍼티 역할과 함께, 보호 도막과 균열 부위의 연결을 매개하는 프라이머(1) 고유의 의미에 따른 역할을 함께 수행할 수 있다.The primer (1) of the present invention mixed in such a mixing ratio can play a role according to the inherent meaning of the primer (1), which mediates the connection between the protective coating and the crack area, as well as a known putty role to fill the crack area. have.

즉, 본 발명의 프라이머(1)는 퍼티를 별도로 구비하지 않고도 균열 보수 시공을 가능하게 하는바, 시공의 준비 과정 및 실행 과정을 간략화 처리할 수 있어 숙련도가 낮은 시공자도 콘크리트 구조물의 균열을 보다 용이하게 보수 및 시공할 수 있는 특성을 제공한다.In other words, the primer (1) of the present invention enables crack repair and construction without a separate putty, and it is possible to simplify the preparation and execution process of construction, so that even a low-skilled constructor can more easily crack cracks in concrete structures. It provides characteristics that can be easily repaired and constructed.

도 2는 본 발명의 접착성 보강제를 제조하는 방법을 도시한 순서도이다.Figure 2 is a flow chart showing a method of manufacturing the adhesive reinforcing agent of the present invention.

본 발명의 접착성 보강제(30)는 상술하였듯이 부틸아크릴레이트(Butyl acrylate) 및 탄산칼슘 및 PP Wax(Polypropylene wax)를 포함하여 제조될 수 있다.The adhesive reinforcing agent 30 of the present invention may be prepared including butyl acrylate, calcium carbonate, and PP Wax (Polypropylene wax), as described above.

이때, 부틸아크릴레이트는 우수한 접착성을 가진 아크릴 수지를 제조하기 위한 단량체이고, 탄산칼슘은 접착성 보강제(30)의 부피를 증가 및 접착능을 보강하는 충전재이며, PP Wax는 접착성 보강제(30)의 점도 조절제이다.At this time, butyl acrylate is a monomer for manufacturing an acrylic resin having excellent adhesiveness, calcium carbonate is a filler that increases the volume of the adhesive reinforcing agent 30 and reinforces adhesiveness, and PP Wax is an adhesive reinforcing agent (30). ) Is a viscosity modifier.

더불어, 접착성 보강제(30)의 제조에는 개시제인 TBPO(t-Butyl peroxy octate), 용매인 MEK(Methyl ethyl ketone), 비이온 계면활성제인 PELE(Polyoxyethylene lauryl ether)가 포함될 수 있다.In addition, the preparation of the adhesive reinforcing agent 30 may include t-butyl peroxy octate (TBPO) as an initiator, methyl ethyl ketone (MEK) as a solvent, and polyoxyethylene lauryl ether (PELE) as a nonionic surfactant.

이러한 물질들을 포함한 접착성 보강제(30)는 1차 물질 제조 단계(S100), 2차 물질 제조 단계(S110), 접착성 보강제 혼합 단계(S120)를 거쳐 제조될 수 있다.The adhesive reinforcing agent 30 including these materials may be manufactured through a primary material manufacturing step (S100), a secondary material manufacturing step (S110), and an adhesive reinforcing agent mixing step (S120).

먼저, 1차 물질 제조 단계(S100)는 부틸아크릴레이트 65 내지 75 중량부, MEK(Methyl ethyl ketone) 30 내지 40 중량부, TBPO(t-Butyl peroxy octate) 5 내지 10 중량부를 100 내지 130℃에서 100 내지 150rpm으로 2 내지 4시간 동안 혼합하여 1차 물질을 제조하는 과정이다.First, the first material preparation step (S100) is butyl acrylate 65 to 75 parts by weight, MEK (Methyl ethyl ketone) 30 to 40 parts by weight, TBPO (t-Butyl peroxy octate) 5 to 10 parts by weight at 100 to 130 °C It is a process of preparing a primary material by mixing at 100 to 150 rpm for 2 to 4 hours.

여기서, 개시제인 TBPO를 통해 부틸아크릴레이트가 중합되어 우수한 접착성을 보유한 에폭시 수지(10)인 1차 물질이 제조될 수 있는바, 용매인 MEK로 용해 및 분산됨으로써, 1차 물질은 혼합이 가능한 점액상으로 제조될 수 있다.Here, butyl acrylate is polymerized through TBPO, an initiator, so that a primary material, an epoxy resin 10 having excellent adhesion, can be prepared. By dissolving and dispersing in MEK as a solvent, the primary material can be mixed. It can be prepared in a slime form.

다음, 2차 물질 제조 단계(S110)는 탄산칼슘 70 내지 80 중량부, PELE(Polyoxyethylene lauryl ether) 20 내지 30 중량부를 40 내지 60℃에서 30 내지 60분 동안 혼합한 다음 고체상을 수득하여 2차 물질을 제조하는 과정이다.Next, in the second material manufacturing step (S110), 70 to 80 parts by weight of calcium carbonate and 20 to 30 parts by weight of PELE (polyoxyethylene lauryl ether) are mixed at 40 to 60° C. for 30 to 60 minutes, and then a solid phase is obtained to obtain a secondary material. It is the process of manufacturing.

이때, 흡착성을 가진 충전재인 탄산칼슘에 비이온성 계면활성제인 PELE가 흡착되어 1차 물질과의 혼합의 용이성을 도모하고 탄산칼슘이 균열 부위의 콘크리트를 산화시킬 수도 있는 개연성을 해소할 수 있다.At this time, PELE, a nonionic surfactant, is adsorbed to calcium carbonate, a filler having adsorption, to facilitate mixing with the primary material, and the possibility that calcium carbonate may oxidize concrete in the cracked area can be eliminated.

마지막으로, 접착성 보강제 혼합 단계(S120)는 1차 물질 70 내지 80 중량부, 상기 PP Wax 10 내지 20 중량부, 상기 2차 물질 10 내지 20 중량부를 100 내지 130℃에서 30 내지 60분 동안 100 내지 150rpm으로 혼합하는 과정이다.Finally, the adhesive reinforcing agent mixing step (S120) is a primary material 70 to 80 parts by weight, the PP Wax 10 to 20 parts by weight, the secondary material 10 to 20 parts by weight 100 for 30 to 60 minutes at 100 to 130 ℃ 100 To 150 rpm.

여기서, PP Wax는 1차 물질과 2차 물질이 혼합된 접착성 보강제(30)의 점도를 적절히 낮추어 본 발명의 프라이머(1)가 균열 부위에 충진되기 용이하도록 할 수 있다.Here, the PP Wax appropriately lowers the viscosity of the adhesive reinforcing agent 30 in which the primary material and the secondary material are mixed, so that the primer 1 of the present invention can be easily filled in the crack area.

이러한 과정을 통해 제조된 접착성 보강제(30)는 흡착성의 2차 물질에 접착성의 1차 물질의 일부가 흡착되는바, 본 발명의 프라이머(1)가 균열 부위에서 경화되기 전까지 2차 물질이 일시적인 고체상 지지체 역할을 수행하여 접착능을 보강할 수 있는 특징을 제공한다.In the adhesive reinforcing agent 30 manufactured through this process, a part of the adhesive primary material is adsorbed to the secondary material of the adsorption, and the secondary material is temporarily cured until the primer 1 of the present invention is cured at the crack site. It provides a feature that can reinforce adhesion by performing the role of a solid support.

도 3은 본 발명의 프라이머를 이용한 균열 보수 공법을 도시한 순서도이고, 도 4는 도 3의 균열 보수 공법으로 적층된 보수 도막을 도시한 단면도이다.3 is a flowchart showing a crack repair method using the primer of the present invention, and FIG. 4 is a cross-sectional view showing a repair coating layer laminated by the crack repair method of FIG. 3.

도 3을 보아 알 수 있듯이, 본 발명의 프라이머(1)를 이용한 균열 보수 공법은 제 1,2,3,4 단계(S500,S510,S520,S530)를 거쳐 균열 부위에 본 발명의 프라이머(1)를 포함한 도막, 즉 보수 도막을 적층시키는 공법이다.As can be seen from Figure 3, the crack repair method using the primer (1) of the present invention is through the first, second, third, and fourth steps (S500, S510, S520, S530) to the crack site of the present invention primer (1) This is a method of laminating a coating film containing ), that is, a repair coating.

우선, 제 1 단계(S500)는 콘크리트 구조물의 균열 부위에 존재할 수 있는 먼지, 콘크리트 조각 등을 제거하는 단계로서, 블로잉, 브러싱 등의 다양한 방법으로 불순물을 제거할 수 있는바, 불순물이 제거된 균열 부위는 본 발명의 프라이머(1)가 충진되었을 시 프라이머(1)의 접착 기능이 온전히 발현될 수 있다.First, the first step (S500) is a step of removing dust and concrete fragments that may exist in cracks of a concrete structure, and impurities can be removed by various methods such as blowing and brushing. When the site is filled with the primer (1) of the present invention, the adhesive function of the primer (1) can be fully expressed.

이러한 불순물 제거 단계에는 공지의 균열 부위 처리 방법인 균열 부위의 수분을 제거하는 과정, 균열 부위 내의 불규칙하게 돌출된 부분을 평탄화 하는 과정 등이 포함될 수 있음은 물론이다.It goes without saying that the impurity removal step may include a process of removing moisture from a cracked area, which is a known crack area treatment method, and a process of flattening irregularly protruding areas within the cracked area.

다음, 제 2 단계(S510)는 도 4에 도시된 같이 균열 부위를 프라이머(1)로 메우는 단계로서, 이때 제 2 단계(S510)에서 충진되는 프라이머(1)를 본 발명에서는 '제 1 프라이머 층(100)'이라 명명한다.Next, the second step (S510) is a step of filling the cracked area with the primer 1 as shown in FIG. 4, and at this time, the primer 1 filled in the second step (S510) is used as the'first primer layer. It is named'(100)'.

제 1 프라이머 층(100)의 경화 시간은 균열 부위의 넓이 및 깊이에 따라 다양할 수 있는바 제 1 프라이머 층(100)이 완전히 경화될 수 있는 충분한 경화 시간을 설정하는 것이 바람직하다.Since the curing time of the first primer layer 100 may vary depending on the width and depth of the crack area, it is preferable to set a sufficient curing time for the first primer layer 100 to be completely cured.

이어서, 제 3 단계(S520)는 상술한 제 2 단계(S510)에서 제 1 프라이머 층(100)이 충진 된 균열 부위의 표면에 프라이머(1)를 도포 및 경화하는 단계로서, 보수 도막의 기초 층이 형성될 수 있는바, 이때 도포되는 프라이머(1)를 본 발명에서는 '제 2 프라이머 층(200)'이라 명명한다.Subsequently, the third step (S520) is a step of applying and curing the primer 1 on the surface of the crack area filled with the first primer layer 100 in the second step (S510) described above. As can be formed, the primer 1 applied at this time is referred to as a'second primer layer 200' in the present invention.

이때, 프라이머(1)를 제 2 단계(S510)와 제 3 단계(S520)로 나누어 충진 및 도포함으로써, 균열 부위가 제 2 프라이머 층(200)로 덮어져(즉, 전체적인 두께가 두꺼워져) 균열 부위에 충진 된 제 1 프라이머 층(100)이 완전히 경화하지 않아 유동성이 생길 수 있는 개연성을 해소할 수 있다. At this time, by dividing the primer 1 into the second step (S510) and the third step (S520) and filling and applying, the crack area is covered with the second primer layer 200 (that is, the overall thickness is increased) Since the first primer layer 100 filled in the region is not completely cured, the possibility that fluidity may occur may be eliminated.

다음, 제 4 단계(S530)는 제 2 프라이머 층(200) 상에 보호층(300)을 도포하여 보수 도막의 표층(도 4에서 최상층)을 적층하는 단계로서, 보호층(300)은 아디프산(Adipic acid) 및 HDI(Hexamethylene diisocyanate)를 포함하여 제 1 프라이머 층(100)에 강하게 접착될 수 있고 방수성 및 내마모성을 겸비한 층일 수 있는바, 보호층(300)의 구체적인 제조 방법은 후술하도록 한다.Next, the fourth step (S530) is a step of laminating the surface layer (the uppermost layer in FIG. 4) of the repair coating film by applying the protective layer 300 on the second primer layer 200, and the protective layer 300 is A layer including acid (Adipic acid) and HDI (Hexamethylene diisocyanate) may be strongly adhered to the first primer layer 100 and may be a layer having both waterproof and abrasion resistance, and a specific method of manufacturing the protective layer 300 will be described later. .

이러한 본 발명의 보수 공법은 제 1 프라이머 층(100)으로 균열 부위를 메우는 역할 및 기초 층을 이루는 역할을 모두 수행토록 함으로써 별도의 퍼티제(충진제)를 구비하지 않아도 되는바, 이를 통해 시공의 용이성을 도모할 수 있다.Such a repair method of the present invention does not require a separate putty (filler) by performing both the role of filling the crack area and the role of forming the base layer with the first primer layer 100, thereby ease of construction. You can plan.

또한, 제 2 프라이머 층(200) 상에 보호층(300)을 적층함으로써, 균열 부위가 침수, 마모 되어 균열이 더욱 심해지는 것을 방지하는 특성을 제공한다. 즉, 콘크리트 구조물의 안전성 유지를 도모할 수 있다. In addition, by laminating the protective layer 300 on the second primer layer 200, it provides a property of preventing the cracks from becoming more severe due to immersion and abrasion of the cracks. In other words, it is possible to maintain the safety of the concrete structure.

도 5는 도 4의 보수 도막의 또 다른 실시예를 도시한 단면도이다.5 is a cross-sectional view showing another embodiment of the repair coating film of FIG. 4.

도 5를 보아 알 수 있듯이, 균열 부위에 충진 된 제 1 프라이머 층(100)의 표면에는 방수제(400)가 도포되어 균열 부위로의 수분이 침투하는 것을 방지할 수 있다.As can be seen from FIG. 5, a waterproofing agent 400 is applied to the surface of the first primer layer 100 filled in the cracked area to prevent moisture from penetrating into the cracked area.

방수제(400)는 상술한 제 2 단계(S510)와 제 3 단계(S520)의 사이에 도포되어 도 5와 같이 제 1 프라이머 층(100)과 제 2 프라이머 층(200)의 사이에 포함되는 것이 가능한데, 이때 균열 부위의 상부(도 5에서 균열 부위의 가장 넓은 윗부분)보다 조금 넓게 도포되어 균열 부위로의 침수 방지를 극대화 하는 것이 바람직하다.The waterproofing agent 400 is applied between the second step (S510) and the third step (S520) and is included between the first primer layer 100 and the second primer layer 200 as shown in FIG. 5. In this case, it is preferable to apply a little wider than the upper part of the crack (the widest upper part of the crack region in FIG. 5) to maximize the prevention of inundation into the crack region.

이때, 방수제(400)는 PVDF(Polyvinylidene fluoride)를 포함하는 것이 가능한바, PVDF는 높은 표면 에너지를 가진 고분자로서, 마찬가지로 높은 표면 에너지를 가진 물과 큰 접촉각을 형성하는 소수성을 보인다.At this time, the waterproofing agent 400 may contain polyvinylidene fluoride (PVDF), and PVDF is a polymer having a high surface energy, and shows hydrophobicity that forms a large contact angle with water having a high surface energy.

더불어, 방수제(400)에는 PVDF와 같은 소수성 고분자인 PFA(PerFluoro alkoxy), PTFE(Polytetra fluoro ethylene) 등이 함께 사용될 수 있음은 물론이다.In addition, it goes without saying that the waterproofing agent 400 may include hydrophobic polymers such as PVDF, such as PFA (PerFluoro alkoxy) and PTFE (Polytetra fluoro ethylene).

이러한 방수제는 균열 부위로 수분이 침투해 알칼리성을 유지해야 하는 석재의 pH를 낮추는 것을 막음으로써, 균열 부위가 약화되어 콘크리트 구조물이 불안정 해지는 것을 방지하는 역할을 수행한다.These waterproofing agents play a role of preventing the concrete structure from becoming unstable due to weakening of the crack area by preventing moisture from penetrating into the cracked area and lowering the pH of the stone that must maintain alkalinity.

또 다른 실시예로서, 다시 도 5를 보아 알 수 있듯이 제 3 단계(S520)에서 도포되는 제 2 프라이머 층(200)와 제 4 단계(S530)에서 도포되는 보호층(300) 사이에는 흡습제(500)가 도포될 수 있다.As another embodiment, as can be seen from FIG. 5 again, between the second primer layer 200 applied in the third step (S520) and the protective layer 300 applied in the fourth step (S530), a desiccant 500 ) Can be applied.

흡습제(500)는 제 2 프라이머 층(200)과 보호층(300) 사이의 수분을 흡수 제거하는 역할을 것으로서, 수분에 의해 접착이 잘 일어나지 않아 층의 분리가 일어나는 것을 방지할 수 있다. 또한, 보수 도막이 태양열 등으로 가열 되었을 시 수분이 기화하여 해당 부위가 들뜨는 것을 방지할 수도 있다.The desiccant 500 serves to absorb and remove moisture between the second primer layer 200 and the protective layer 300, and may prevent separation of the layer due to poor adhesion due to moisture. In addition, when the repair coating is heated by solar heat, moisture can evaporate and prevent the area from being lifted.

더불어, 흡습제(500)는 흡습 기능을 보유한 실리카졸, 활성탄, 숯, 규조토 등의 재료들을 적어도 하나 이상 포함할 수 있는바, 가능한 작은 크기의 입자로 분쇄 및 도포하여 제 2 프라이머 층(200)과 보호층(300)의 접착을 저해하지 않도록 하는 것이 바람직하다.In addition, the desiccant 500 may contain at least one or more materials such as silica sol, activated carbon, charcoal, and diatomaceous earth having a moisture absorption function, and the second primer layer 200 and the second primer layer 200 are pulverized and coated into particles of as small size as possible. It is preferable not to impede the adhesion of the protective layer 300.

즉, 도 5에서는 표현의 편의상 흡습제(500)가 일정 두께를 가지는 층 형태로 도포된 것을 도시하였지만 흡습제(500)가 도포되는 형태는 도면에 한정된 것은 아니다.That is, in FIG. 5, for convenience of expression, the desiccant 500 is applied in the form of a layer having a certain thickness, but the form in which the desiccant 500 is applied is not limited to the drawings.

도 6은 본 발명의 보호층을 제조하는 방법을 도시한 순서도이다.6 is a flow chart showing a method of manufacturing the protective layer of the present invention.

상술한 보호층(300)은 제 1 용액 제조 단계(S200), 제 2 용액 제조 단계(S210), 보호층 혼합 단계(S220)를 거쳐 제조될 수 있다.The above-described protective layer 300 may be manufactured through a first solution manufacturing step (S200), a second solution manufacturing step (S210), and a protective layer mixing step (S220).

먼저, 제 1 용액 제조 단계(S200)는 아디프산(Adipic acid) 30 내지 40 중량부, TMP(Trimethylol propane) 30 내지 40 중량부, 1,4-부테인다이올(1,4-Butanediol) 30 내지 40 중량부를 120 내지 150℃에서 30 내지 60분 동안 혼합하여 제 1 용액을 제조하는 과정이다.First, the first solution preparation step (S200) is adipic acid (Adipic acid) 30 to 40 parts by weight, TMP (Trimethylol propane) 30 to 40 parts by weight, 1,4-butanediol (1,4-Butanediol) This is a process of preparing a first solution by mixing 30 to 40 parts by weight at 120 to 150°C for 30 to 60 minutes.

여기서, 아디프산은 4개의 탄소 사슬의 양쪽 말단에 두 개의 카복시기를 가진 물질로서 후술한 HDI와 폴리우레탄 결합을 형성할 수 있다. 더불어, 1,4-부테인다이올은 사슬 연장제로서 보호층(300)의 분자 사슬이 길게 형성되도록 유도하는바 이를 통해 보호층(300)의 내마모성 및 방수성을 보강시킬 수 있고, TMP는 제 1 용액의 용매 역할을 수행한다.Here, adipic acid is a material having two carboxyl groups at both ends of the four carbon chains and can form a polyurethane bond with HDI described later. In addition, 1,4-butanediol, as a chain extender, induces the molecular chain of the protective layer 300 to be elongated, thereby reinforcing the abrasion resistance and waterproofness of the protective layer 300, and TMP 1 Serves as a solvent for the solution.

다음, 제 2 용액 제조 단계(S210)는 제 1 용액 40 내지 50 중량부, HDI(Hexamethylene diisocyanate) 30 내지 40 중량부, DPP(Dimethyl phenyl phosphate) 20 내지 30 중량부를 30 내지 60℃에서 1 내지 2시간 동안 혼합하여 제 2 용액을 제조하는 과정이다.Next, the second solution preparation step (S210) is the first solution 40 to 50 parts by weight, HDI (Hexamethylene diisocyanate) 30 to 40 parts by weight, DPP (Dimethyl phenyl phosphate) 20 to 30 parts by weight at 30 to 60 ℃ 1 to 2 This is a process of preparing a second solution by mixing for a period of time.

이때, HDI는 상술하였듯이 아디프산의 카복시기의 일부인 수산기와 폴리우레탄 결합을 형성하는바, 폴리우레탄 결합을 형성하는 정석적인 구성인 이소사이아네이트와 폴리올의 반응이 아니므로 중합이 지연된 특징을 가진다. 또한, DPP는 제 2 용액에 인을 부가하여 접착성을 보강하는 역할을 수행한다.At this time, HDI forms a polyurethane bond with a hydroxyl group, which is a part of the carboxy group of adipic acid, as described above. Have. In addition, DPP plays a role of reinforcing adhesion by adding phosphorus to the second solution.

마지막으로, 보호층 혼합 단계(S220)는 제 2 용액 85 내지 99 중량부, AIBN(Azobisisobutyronitrile) 1 내지 15 중량부를 30 내지 60℃에서 30 내지 60분 동안 혼합하는 과정이다.Finally, the protective layer mixing step (S220) is a process of mixing 85 to 99 parts by weight of the second solution and 1 to 15 parts by weight of AIBN (Azobisisobutyronitrile) at 30 to 60° C. for 30 to 60 minutes.

여기서, AIBN은 광개시제로서 열 및 자외선을 받아 질소가 분리되며 라디칼이 생성되어 중합이 지연된 제 2 용액을 중합시킬 수 있는바, 보호층 혼합 단계(S220)는 빛이 차단된 상태에서 진행되고, 완성된 보호층(300) 또한 빛을 차단한 상태에서 보관하는 것이 바람직하다.Here, AIBN is a photoinitiator that receives heat and ultraviolet rays to separate nitrogen and generates radicals to polymerize the second solution whose polymerization is delayed, and the protective layer mixing step (S220) proceeds in a state where light is blocked, and is completed. The protective layer 300 is also preferably stored in a state where light is blocked.

이러한 과정을 통해 제조된 보호층(300)은 중합이 지연되고 광개시제가 포함된 상태로 보관되었다가 상술한 제 4 단계(S530)에 도포되어 열 및 자외선을 받아 중합됨으로써 도포 및 경화가 용이한 특성을 제공할 수 있다.The protective layer 300 manufactured through this process is easy to apply and cure by delaying polymerization and being stored in a state containing a photoinitiator, and then being applied to the fourth step (S530) and polymerized by receiving heat and ultraviolet rays. Can provide.

또한, 상술한 바와 같이 내마모성 및 방수성이 보강되어 보수 도막의 표면 기능에 도움을 줄 수 있고, 접착성이 증진되어 제 2 프라이머 층(200)과 강하게 접착될 수 있다.In addition, as described above, abrasion resistance and waterproofness are reinforced to help the surface function of the repair coating film, and adhesion may be enhanced to strongly adhere to the second primer layer 200.

나아가, 상술한 보강층 혼합 단계(S220)에는 ETMS(Ethoxy trimethylsilane)을 포함하는 단열재가 포함될 수 있다.Further, the above-described reinforcing layer mixing step (S220) may include an insulating material including ETMS (Ethoxy trimethylsilane).

구체적으로, 단열재가 포함된 보강층 혼합 단계(S220)는 제 2 용액 85 내지 90 중량부, 단열재 5 내지 10 중량부, AIBN(Azobisisobutyronitrile) 1 내지 5 중량부를 30 내지 60℃에서 30 내지 60분 동안 혼합하는 단계인 것이 가능하다.Specifically, the step of mixing the reinforcing layer containing the insulation material (S220) is a mixture of 85 to 90 parts by weight of the second solution, 5 to 10 parts by weight of the insulation material, 1 to 5 parts by weight of AIBN (Azobisisobutyronitrile) at 30 to 60° C. for 30 to 60 minutes It is possible that it is a step to do.

이때, 단열재는 보수 도막의 상층(표층)에 위치하는 보호층(300) 측의 열이 균열 부위로 전달되는 것을 일정량 감소시키는 것으로서, 균열 부위로 열이 전달되어 온도 변화로 인해 균열이 심해지는 것을 방지하는 기능을 제공한다.At this time, the heat insulator reduces the transfer of heat from the protective layer 300 located on the upper layer (surface layer) of the repair coating to the crack area by a certain amount. Provides the ability to prevent.

이러한 단열재는 전구체 용액 제조 단계, 겔 제조 단계, 가압 건조 단계를 거쳐 제조될 수 있다. Such an insulating material may be manufactured through a precursor solution manufacturing step, a gel manufacturing step, and a pressure drying step.

먼저, 전구체 제조 단계는 ETMS 60 내지 70 중량부, 물 20 내지 30 중량부, 염산 10 내지 20 중량부를 20 내지 40℃에서 1 내지 3시간 동안 혼합하여 전구체 용액을 제조하는 과정이다.First, the precursor preparation step is a process of preparing a precursor solution by mixing 60 to 70 parts by weight of ETMS, 20 to 30 parts by weight of water, and 10 to 20 parts by weight of hydrochloric acid for 1 to 3 hours at 20 to 40°C.

여기서, ETMS는 단열재의 단열 기능을 제공하는 실란계열의 전구체로서 물과 염산의 혼합액에서 가수분해 되는 것이 가능하다. Here, ETMS can be hydrolyzed in a mixture of water and hydrochloric acid as a silane-based precursor that provides a thermal insulation function of an insulating material.

다음, 겔 제조 단계는 전구체 용액 70 내지 80 중량부, 암모니아 20 내지 30 중량부를 20 내지 40℃에서 20 내지 25kHz의 초음파를 가하면서 30 내지 60분 동안 혼합하여 겔을 제조하는 과정이다.Next, the gel preparation step is a process of preparing a gel by mixing 70 to 80 parts by weight of a precursor solution and 20 to 30 parts by weight of ammonia for 30 to 60 minutes while applying ultrasonic waves of 20 to 25 kHz at 20 to 40°C.

이때, 암모니아는 가수분해 된 전구체 용액을 다시 축중합 하는바, 이 과정을 통해 미세한 크기의 ETMS입자가 포함된 겔을 제조할 수 있다.At this time, since the ammonia is condensation polymerization of the hydrolyzed precursor solution again, a gel containing ETMS particles having a fine size can be prepared through this process.

마지막으로, 가압 건조 단계는 겔 80 내지 90 중량부, TMCS(Trichloro methyl silane) 10 내지 20 중량부를 20 내지 40℃에서 200 내지 300rpm으로 1 내지 2시간 동안 혼합한 다음 100 내지 120℃ 및 10 내지 20bar에서 3 내지 5시간 동안 가압 건조하는 과정이다. Finally, in the pressure drying step, 80 to 90 parts by weight of the gel and 10 to 20 parts by weight of TMCS (Trichloro methyl silane) are mixed for 1 to 2 hours at 200 to 300 rpm at 20 to 40°C, and then 100 to 120°C and 10 to 20 bar. It is a process of drying under pressure for 3 to 5 hours.

여기서, 100 내지 120℃ 및 10 내지 20bar에서 3 내지 5시간 동안 가압 건조하는 도중 잔여 용매가 증발하여 분말상의 단열재가 제조될 수 있다. 더불어, TMCS는 겔의 표면을 개질해 점착성을 부가하는 물질로서, 표면이 개질된 겔인 단열재는 보호층(300)과 동떨어지지 않도록 포함되는 것이 가능하다.Here, during pressure drying at 100 to 120° C. and 10 to 20 bar for 3 to 5 hours, the residual solvent evaporates to produce a powdery heat insulating material. In addition, TMCS is a material that adds adhesion by modifying the surface of the gel, and the insulating material, which is a gel whose surface has been modified, may be included so as not to be separated from the protective layer 300.
