Description
본 발명은 주차장 바닥 보수보강공법에 관한 것으로서, 보다 상세하게는 에폭시및우레탄하도제가 균열을 메우기 때문에, 에폭시및우레탄하도제 도장 후에 별도의 퍼티제로 균열 메울 필요가 없으므로 콘크리트 주차장 바닥을 간단하게 보수보강할 수 있는 새로운 방식의 주차장 바닥 보수보강공법에 관한 것이다. The present invention relates to a parking lot floor repair and reinforcement method, and more particularly, since epoxy and urethane primers fill the cracks, there is no need to fill the cracks with a separate putty after painting the epoxy and urethane primers, so the concrete parking lot floor is simply repaired and reinforced. It is about a new method of repairing and reinforcing the parking lot floor.
일반적으로 콘크리트 건축물의 지하주차장은 방수도료로 도장하여 방수처리한다. 그런데 콘크리트 구조물은 재료의 특성상 시간이 경과함에 따라 균열이 발생되는데, 지하주차장의 콘크리트바닥도 예외는 아니다.In general, underground parking lots of concrete buildings are waterproofed by painting with waterproof paint. However, the concrete structure cracks over time due to the nature of the material, and the concrete floor of the underground parking lot is no exception.
구조물에 발생한 균열부위는 보수를 하지 않게 되면 균열이 더욱 확대되어 강도에 지대한 영향을 미치게 되므로 보수공사를 하여야 하는데, 흔히, 에폭시및우레탄하도제를 도장을 하여 균열을 보수한다.If the cracks in the structure are not repaired, the cracks expand further and have a great influence on the strength. Therefore, repair work is required. Often, the cracks are repaired by painting an epoxy or urethane primer.
그런데, 에폭시및우레탄하도제가 묽기 때문에, 에폭시및우레탄하도제를 균열부위에 도장하면 에폭시및우레탄하도제가 균열 속으로 유입되어, 균열된 면을 따라 얇은 도막을 형성하기 때문에 에폭시및우레탄하도제를 코팅한 후에도 균열이 잔존된다. 따라서 일반적으로는 에폭시및우레탄하도제를 도장한 후에 별도의 퍼티재를 발라서 균열을 메운 다음, 방수제로 마감포장을 하여 공사를 마무리한다. However, since epoxy and urethane primers are thin, if epoxy and urethane primers are coated on the crack, the epoxy and urethane primers flow into the crack and form a thin film along the cracked surface. Even after the cracks remain. Therefore, in general, after painting the epoxy and urethane primer, a separate putty material is applied to fill the cracks, and the construction is finished by finishing and packaging with a waterproofing agent.
이와 같이 에폭시및우레탄하도제를 바르고, 그 위에 별도의 퍼티제를 발라야 하므로 보수작업이 번거롭고 시간도 많이 소요되며, 공사비용도 상승된다. In this way, since epoxy and urethane undercoat must be applied and a separate putty agent must be applied on top of it, repair work is cumbersome and time consuming, and construction cost is increased.
본 발명은 상기와 같은 점에 착안하여 제안된 것으로서, 에폭시및우레탄하도제가 균열을 메우기 때문에, 에폭시및우레탄하도제 도장 후에 별도의 퍼티제로 균열을 메울 필요가 없으므로 시공이 간단하고 공사시간도 단축되며, 기공사비용도 절감되는 새로운 방식의 주차장 바닥 보수보강공법을 제공하는 것이다.The present invention was proposed in light of the above points, and since the epoxy and urethane primers fill the cracks, there is no need to fill the cracks with a separate putty after painting the epoxy and urethane primers, so the construction is simple and the construction time is shortened. It is to provide a new method of repairing and reinforcing the parking lot floor, which also reduces the construction cost.
본 발명의 일 특징에 따르면, 콘크리트 주차장 바닥의 균열이 발생된 부위의 이물질을 제거하는 전처리과정; 상기 에폭시하도제와 규사를 혼합하는 과정; 및 상기 규사가 혼합된 에폭시하도제를 전처리과정에서 이물질이 제거된 주차장 바닥의 균열부위에 도포하는 과정;을 포함하는 것을 특징으로 하는 주차장 바닥 보수보강공법이 제공된다.According to one feature of the present invention, a pre-treatment process of removing foreign substances from a cracked area of the concrete parking lot floor; Mixing the epoxy primer and the silica sand; And a process of applying the epoxy undercoat mixed with the silica sand to the cracked part of the parking lot floor from which foreign substances have been removed during the pretreatment process. A parking lot floor repair and reinforcement method is provided.
본 발명의 다른 특징에 따르면, 상기 규사는 실란커플링제로 표면이 개질된 것이 사용된다. According to another feature of the present invention, the silica sand is used that has a surface modified with a silane coupling agent.

n-아미노에틸피페라진(n-aminoethylpiperazine) 15~35중량부, 1,3 벤젠디메탄아민(1,3 Benzenedimethanamine) 20~25중량부, 변성 지방족 아민 3~10중량부, 벤질알코올(benzyl alcohol) 3~15중량부, 비스페놀 A의 디글리시딜 에테르(diglycidly ether of bisphenol A) 5~15중량부를 포함하는 경화제;를 포함하며,15 to 35 parts by weight of n-aminoethylpiperazine, 20 to 25 parts by weight of 1,3 Benzenedimethanamine, 3 to 10 parts by weight of a modified aliphatic amine, benzyl alcohol ) 3 to 15 parts by weight, a curing agent containing 5 to 15 parts by weight of a diglycidly ether of bisphenol A; includes,
상기 주제와 경화제는 1: 0.5~1 중량비로 혼합되고, The main material and the curing agent are mixed in a weight ratio of 1: 0.5 to 1,
상기 에폭시하도제와 규사를 혼합하는 과정에서는 에폭시하도제 100중량부에 규사를 10~20중량부 혼합한다. In the process of mixing the epoxy undercoat and silica sand, 10 to 20 parts by weight of silica is mixed with 100 parts by weight of the epoxy undercoat.
이상과 같은 구성을 가지는 본 발명은 에폭시및우레탄하도제에 규사를 혼합하여 콘크리트 주차장 바닥의 균열을 보수하기 때문에, 규사가 혼합된 에폭시및우레탄하도제를 균열에 도포하면 에폭시및우레탄하도제가 균열을 메우기 때문에, 균열을 메우기 위해 에폭시및우레탄하도제를 도장한 후에 별도의 퍼티제로 균열을 메울 필요가 없다. 따라서 시공이 간단하고 공사시간도 단축되고, 공사비용도 절감된다. Since the present invention having the above configuration repairs cracks in the concrete parking lot floor by mixing silica sand with epoxy and urethane undercoat, when epoxy and urethane undercoat mixed with silica is applied to the crack, the epoxy and urethane undercoat prevent cracking. Because of the filling, there is no need to fill the crack with a separate putty after painting the epoxy and urethane primer to fill the crack. Therefore, construction is simple, construction time is shortened, and construction cost is also reduced.
이하에서, 본 발명을 구체적인 실시예를 통해 좀 더 구체적으로 설명한다. Hereinafter, the present invention will be described in more detail through specific examples.
본 발명의 제1실시예에서는 에폭시및우레탄하도제에 규사를 혼합하고 도장하여 콘크리트 주차장 바닥을 보수한다. 본 발명은 다음과 같은 공정으로 처리된다.In the first embodiment of the present invention, a concrete parking lot floor is repaired by mixing and painting silica sand with an epoxy and urethane primer. The present invention is processed in the following process.
1) 균열이 발생되어 보수를 하여야 할 부위의 이물질을 제거하고, 표면에 요철이 있는 경우에는 그라인드로 갈아낸다.1) Remove foreign substances from areas to be repaired due to cracks, and grind if there are irregularities on the surface.
2) 에폭시및우레탄하도제와 규사를 혼합한다.2) Mix the epoxy and urethane primer and silica sand.
에폭시및우레탄하도제 100중량부에 규사를 10~20중량부 정도를 혼합한다. 규사가 상기 수준보다 적게 혼합되면 규사에 의한 효과를 기대하기 곤란하고, 상기 수준보다 많이 혼합되면 규사가 도막에서 탈리될 우려가 높아지고 규사에 의해 도장면에 과도한 요철이 발생되는 문제점을 가진다. 바람직하게는 규사는 입도가 2~350㎛ 정도이며, 둥글게 가공처리된 것을 사용한다. About 10 to 20 parts by weight of silica is mixed with 100 parts by weight of the epoxy and urethane primer. If the silica sand is mixed less than the above level, it is difficult to expect the effect of the silica sand, and if the silica sand is mixed more than the above level, there is a problem that the silica sand may be separated from the coating film, and excessive irregularities are generated on the painted surface by the silica sand. Preferably, the silica sand has a particle size of about 2 to 350 μm, and a round processed one is used.
3) 규사가 혼합된 에폭시하도제를 균열부위에 도장한다.3) Apply an epoxy primer mixed with silica sand on the cracks.
롤러나 밀대 등을 사용하여 규사가 혼합된 에폭시및우레탄하도제를 균열부위에 도장한다. 에폭시및우레탄하도제에 규사가 혼합되어 있기 때문에 에폭시및우레탄하도제가 균열을 메우게 된다. Apply epoxy and urethane undercoat mixed with silica sand to the cracks using a roller or a pusher. Since silica sand is mixed with the epoxy and urethane primers, the epoxy and urethane primers fill the cracks.
4) 상도제를 도장한다. 4) Paint the top coat.
에폭시및우레탄하도제가 건조되면, 그 위에 에폭시 또는 우레탄방수제를 상도제로 도장하여 보수공사를 마무리한다. 전술한 바와 같이, 에폭시및우레탄하도제가 균열을 메우기 때문에, 상도제가 깔끔하게 도장되어 균열부위가 효과적으로 보수된다.When the epoxy and urethane primers are dried, finish the repair work by coating the epoxy or urethane waterproofing agent with the top coat. As described above, since the epoxy and urethane primers fill the cracks, the top coat is neatly painted to effectively repair the cracked area.
이와 같은 구성을 가지는 본 발명은 에폭시하도제에 규사를 혼합하여 균열부위에 도장하기 때문에, 에폭시및우레탄하도제를 도장한 후에 균열을 메우기 위해 별도의 퍼티제를 바를 필요가 없으며, 따라서 시공이 간편하고 시간도 단축되며, 비용도 절감된다. In the present invention having such a configuration, since silica sand is mixed with an epoxy undercoat and coated on the cracks, there is no need to apply a separate putty to fill the cracks after coating the epoxy and urethane undercoats, so construction is simple. Time and cost are reduced.
이하에서는 본 발명의 다른 실시예를 설명하되, 전술한 실시예와 동일한 구성 및 효과에 대해서는 설명을 생략한다.Hereinafter, other embodiments of the present invention will be described, but descriptions of the same configuration and effects as those of the above-described embodiments will be omitted.
본 발명의 제2실시예에서는 실란커플링제로 표면이 개질된 규사를 에폭시하도제에 혼합한다. 규사가 실란커플링제로 표면이 개질되면, 이질재료 간의 결합력과 시공면의 부착력이 향상되며, 에폭시하도제의 기계적 강도, 내수성, 내후성, 내열성 등의 물성이 향상된다. In the second embodiment of the present invention, silica sand whose surface has been modified with a silane coupling agent is mixed with an epoxy primer. When the surface of the silica sand is modified with a silane coupling agent, the bonding strength between dissimilar materials and the adhesion of the construction surface are improved, and physical properties such as mechanical strength, water resistance, weather resistance, and heat resistance of the epoxy primer are improved.
실란커플링제로는 γ-아미노프로필트리메톡시실란(APS: γ-Aminopropyltrimethoxysilane), γ-글리시딜프로필트리메톡시실란(GPS: γ-Glycidylpropyltrimethoxysilane), 비닐메톡시실란(VS:Vinylmethoxysilane), γ-멜캅토프로필트리메톡시실란(MGPS: γ-Mercaptopropyltrimethoxysilane), γ-메타크릴옥시프로필트리메톡시실란(MPS: γ-Methacryloxypropyltrimethoxysilane), γ-아미노프로필메틸디에톡시실란(APDES: γ-Aminopropylmethyldiethoxysilane), γ-아미노프로필메틸트리에톡시실란(APTES: γ-Aminopropylmethyltriethoxysilane), 3-글리시독시프로필트리메톡시실란(GPTMS: 3-glycidoxypropyltrimethoxysilane) 및 이들의 혼합물로 이루어진 군에서 선택되는 하나 이상인 것이 사용된다. Silane coupling agents include γ-aminopropyltrimethoxysilane (APS: γ-Aminopropyltrimethoxysilane), γ-glycidylpropyltrimethoxysilane (GPS: γ-Glycidylpropyltrimethoxysilane), vinylmethoxysilane (VS: Vinylmethoxysilane), γ -Melcaptopropyltrimethoxysilane (MGPS: γ-Mercaptopropyltrimethoxysilane), γ-methacryloxypropyltrimethoxysilane (MPS: γ-Methacryloxypropyltrimethoxysilane), γ-aminopropylmethyldiethoxysilane (APDES: γ-Aminopropylmethyldiethoxysilane), One or more selected from the group consisting of γ-aminopropylmethyltriethoxysilane (APTES: γ-Aminopropylmethyltriethoxysilane), 3-glycidoxypropyltrimethoxysilane (GPTMS: 3-glycidoxypropyltrimethoxysilane), and mixtures thereof are used.
실란커플링제로 표면이 개질된 규사가 혼합된 에폭시하도제를 사용하면, 규사가 콘크리트 주차장 바닥면의 시멘트성분과 화학적으로 반응하여 강한 부착강도가 발현되므로 한층 더 부착성 및 내구성 등이 우수한 주차장 바닥면을 형성할 수 있다. When using an epoxy primer mixed with silica sand whose surface has been modified with a silane coupling agent, the silica sand chemically reacts with the cement component of the concrete parking lot floor to develop a strong adhesion strength, so the parking lot floor has more excellent adhesion and durability. Cotton can be formed.
본 발명의 제3실시예세서는 상기 에폭시하도제로 비스페놀 A의 디글리시딜 에테르(Diglycidyl ether of bisphenol A) 50~65중량부, 1,6-비스(2,3-에폭시프로폭시)헥산(1,6- Bis(2,3-epoxypropoxy)hexane) 10~20중량부, 충진제 1~6중량부, 소포제는 0.1~3중량부, 습윤제는 0.1~2중량부, 분산제는 0.1~2중량부를 포함하는 주제와, n-아미노에틸피페라진(n-aminoethylpiperazine) 15~35중량부, 1,3 벤젠디메탄아민(1,3 Benzenedimethanamine) 20~25중량부, 변성 지방족 아민 3~10중량부, 벤질알코올(benzyl alcohol) 3~15중량부, 비스페놀 A의 디글리시딜 에테르(diglycidly ether of bisphenol A) 5~15중량부를 포함하는 경화제로 이루어진 2액형 에폭시하도제가 사용된다.In the third exemplary embodiment of the present invention, 50 to 65 parts by weight of bisphenol A diglycidyl ether of bisphenol A as the epoxy primer, 1,6-bis (2,3-epoxypropoxy) hexane ( 1,6-Bis(2,3-epoxypropoxy)hexane) 10 to 20 parts by weight, filler 1 to 6 parts by weight, antifoaming agent 0.1 to 3 parts by weight, wetting agent 0.1 to 2 parts by weight, dispersing agent 0.1 to 2 parts by weight The main substance and, n-aminoethylpiperazine (n-aminoethylpiperazine) 15 to 35 parts by weight, 1,3 benzene dimethanamine (1,3 Benzenedimethanamine) 20 to 25 parts by weight, modified aliphatic amine 3 to 10 parts by weight, A two-component epoxy primer consisting of a curing agent containing 3 to 15 parts by weight of benzyl alcohol and 5 to 15 parts by weight of diglycidly ether of bisphenol A is used.
이러한 에폭시하도제에 대해 좀 더 살펴보면 다음과 같다.A more detailed look at these epoxy primers is as follows.
[주제] [subject]
ⅰ) 비스페놀 A의 디글리시딜 에테르(Diglycidyl ether of bisphenol A)Ⅰ) Diglycidyl ether of bisphenol A
: 비스페놀 A의 디글리시딜 에테르는 이 기술분야에서 알려 있는 에폭시 수지성분이다, 바람직하게는 비스페놀 A디글리시딜 에테르는 50~65중량부 사용된다. : Diglycidyl ether of bisphenol A is an epoxy resin component known in the art. Preferably, 50 to 65 parts by weight of bisphenol A diglycidyl ether is used.
ⅱ) 1,6-비스(2,3-에폭시프로폭시)헥산(1,6- Bis(2,3-epoxypropoxy)hexane)Ii) 1,6-bis (2,3-epoxypropoxy) hexane (1,6- Bis (2,3-epoxypropoxy) hexane)
: 1,6-비스(2,3-에폭시프로폭시)헥산은 반응성 희석제로서, 경화제와의 경화반응에 참여하여 에폭시하도제에 높은 유연성을 부여한다. : 1,6-bis(2,3-epoxypropoxy)hexane is a reactive diluent. It participates in the curing reaction with the curing agent and gives high flexibility to the epoxy primer.
바람직하게는 1,6-비스(2,3-에폭시프로폭시)헥산은 10~20중량부 사용된다. 1,6-비스(2,3-에폭시프로폭시)헥산이 10중량부 미만으로 사용되면 1,6-비스(2,3-에폭시프로폭시)헥산에 의한 효과가 미미하고, 20중량부를 초과하여 사용되면 에폭시하도제 도막의 강도와 내화학성이 현저하게 저하되는 문제가 발생된다.Preferably, 1,6-bis(2,3-epoxypropoxy)hexane is used in an amount of 10 to 20 parts by weight. If less than 10 parts by weight of 1,6-bis(2,3-epoxypropoxy)hexane is used, the effect of 1,6-bis(2,3-epoxypropoxy)hexane is insignificant, and exceeds 20 parts by weight. If used, a problem occurs in that the strength and chemical resistance of the epoxy primer coating film are significantly lowered.
ⅲ) 충진제Iii) filler
: 삼산화안티몬(Antimony trioxide, Sb2O3), 실리카, 알루미나, 산화세륨, 지르코니아 등이 1종 이상 사용된다. : Antimony trioxide (Sb 2 O 3 ), silica, alumina, cerium oxide, zirconia, and more are used.
삼산화안티몬은 난연성도 뛰어나고 분산성도 좋기 때문에 사용이 바람직하다. 실리카로는 흄드 실리카 분말(Fumed silica powder)이 사용된다. 흄드 실리카분말을 사용하면, 에폭시하도제 도막의 저응력화에 한층 더 효과적이다. Antimony trioxide is preferably used because it has excellent flame retardancy and good dispersibility. As silica, fumed silica powder is used. If fumed silica powder is used, it is more effective in reducing the stress of the epoxy primer coating film.
이러한 충전제의 사용량은 에폭시하도제 도막의 저응력성 및 강도 등의 요구 물성에 따라 달라질 수 있는데, 바람직하게는 1~6중량부 사용된다. The amount of the filler used may vary depending on the required physical properties such as low stress and strength of the epoxy primer coating film, and preferably 1 to 6 parts by weight is used.
ⅳ) 기타 첨가제Iv) other additives
: 소포제, 습윤제, 분산제 등과 같은 통상적인 첨가제 중에서 적절히 선택된다. 이들 첨가제는 통상적인 첨가량 수준으로 사용되나, 바람직하게는 소포제는 0.1~3중량부, 습윤제는 0.1~2중량부, 분산제는 0.1~2중량부 사용된다. : It is appropriately selected from conventional additives such as antifoaming agents, wetting agents, and dispersing agents. These additives are used at the usual level of addition, but preferably 0.1 to 3 parts by weight of the antifoaming agent, 0.1 to 2 parts by weight of the wetting agent, and 0.1 to 2 parts by weight of the dispersant are used.
[경화제][Hardener]
n-아미노에틸피페라진(n-aminoethylpiperazine) 15~35중량부, 1,3 벤젠디메탄아민(1,3 Benzenedimethanamine) 20~25중량부, 변성 지방족 아민 3~10중량부, 벤질알코올(benzyl alcohol) 3~15중량부, 비스페놀 A의 디글리시딜 에테르(diglycidly ether of bisphenol A) 5~15중량부를 포함한다.15 to 35 parts by weight of n-aminoethylpiperazine, 20 to 25 parts by weight of 1,3 Benzenedimethanamine, 3 to 10 parts by weight of a modified aliphatic amine, benzyl alcohol ) 3 to 15 parts by weight, and 5 to 15 parts by weight of diglycidly ether of bisphenol A.
이러한 경화제는 지방족 아민과 방향족 아민이 함께 사용되기 때문에 이들 아민의 특성이 잘 조화되어 에폭시하도제 도막에 적절한 물성이 되며, 지방족 아민과 방향족 아민이 상기와 같은 비율로 사용됨에 도작작업에 필요한 적합한 가사시간을 가진다. Since these hardeners are used together with aliphatic amines and aromatic amines, the properties of these amines are well balanced, making them suitable properties for the epoxy primer coating.Since aliphatic amines and aromatic amines are used in the above ratio, suitable housework required for painting work Take time
또한, 변성 지방족 아민이 사용됨에 따라 에폭시하도제 도막의 내수성이 향상된다. 사용가능한 변성 지방족 아민의 종류가 특별히 제한되지는 않으나, 이에 대한 몇 가지를 예시하면 메타자일렌디아민(meta-xylene diamine), 폴리에테르아민 등이 사용가능하다. In addition, as the modified aliphatic amine is used, the water resistance of the epoxy primer coating film is improved. Although the type of the modified aliphatic amine that can be used is not particularly limited, meta-xylene diamine, polyetheramine, etc. may be used to illustrate some examples thereof.
상기 벤질알코올(benzyl alcohol)은 비반응성 희석제로서, 주제와의 반응에 참여하지 않으면서 에폭시하도제 도막에 유연성을 부여한다. 바람직하게는 벤질알코올은 3~15중량부 사용된다. The benzyl alcohol is a non-reactive diluent and imparts flexibility to the epoxy primer coating film without participating in the reaction with the main material. Preferably, 3 to 15 parts by weight of benzyl alcohol is used.
이러한 조성을 가지는 주제와 경화제는 1 : 0.5~1중량비로 혼합되는데, 이러한 조성을 가지는 에폭시하도제는 부착성, 강도, 내화학성, 유연성 등이 우수하기 때문에, 이러한 에폭시하도제를 사용하면, 장기간이 경과하여도 손상되지 않는 내구성이 우수한 주차장 바닥면을 조성할 수 있다.The main material and the curing agent having such a composition are mixed in a ratio of 1: 0.5 to 1 weight, and since the epoxy primer having such a composition has excellent adhesion, strength, chemical resistance, and flexibility, the use of such an epoxy primer may cause a long period of time. Even so, it is possible to create a parking lot floor surface with excellent durability that is not damaged.
