It is hardened to strength and easily fractured by external impact, and when the weight is less than the above weight, the elastic crack repair agent becomes flexible and the resistance to external impact is rather reduced. .
메틸비닐케톤은, 상기 4-브로모싸이클로헥사논과 함께 탄성 균열 보수제의 점도를 조절하여 작업성을 향상시키는 기능을 제공한다.Methyl vinyl ketone provides a function of improving workability by controlling the viscosity of the elastic crack repair agent together with the 4-bromocyclohexanone.
여기서, 메틸비닐케톤은, 1-메톡시-4-페닐싸이클로헥산 100 중량부를 기준으로 40~60 중량부가 첨가되는데, 상기 중량부를 초과하는 경우에는 점도가 높아져 분사나 도포시 평탄화 작업이 불편하고, 상기 중량부를 미만하는 경우에는 점도가 낮아져 경사면의 균열에는 흡착되지 못하고 중력에 의해 아래쪽으로 흐르게 되는 등의 작업성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 범위의 중량부가 유지되는 것이 바람직하다. Here, methyl vinyl ketone is added in 40 to 60 parts by weight based on 100 parts by weight of 1-methoxy-4-phenylcyclohexane. When the amount is less than the above weight part, the viscosity is lowered and there is a problem in that workability is deteriorated, such as not being adsorbed to cracks on the inclined surface and flowing downward by gravity.
2-니트로프로판은, 콘크리트 구조물의 균열 부위에 상기 탄성 균열 보수제의 시공시 코팅 기능을 제공한다.2-Nitropropane provides a coating function when the elastic crack repair agent is applied to cracks in the concrete structure.
여기서, 2-니트로프로판은, 1-메톡시-4-페닐싸이클로헥산 100 중량부를 기준으로 30~50 중량부가 첨가되는데, 상기 중량부를 초과하는 경우에는 보수층의 코팅도가 너무 커지게 되어 시공성이 저하되고, 상기 중량부를 미만하는 경우에는 보수층의 코팅도가 너무 작어져 내구성과 기계적 강도가 저하되는 문제점이 있으므로, 상기와 같은 한정된 범위의 중량부가 유지되는 것이 바람직하다.Here, 2-nitropropane is added in 30 to 50 parts by weight based on 100 parts by weight of 1-methoxy-4-phenylcyclohexane. And, if less than the above weight part, the coating degree of the repair layer is too small and there is a problem that durability and mechanical strength are lowered.
메틸디에틸아민은, 콘크리트 구조물의 균열 부위에 상기 탄성 균열 보수제의 시공시 보수층의 산화 반응 속도를 저하시키고 열교환성을 향상시키는 기능을 제공한다.Methyldiethylamine provides a function of lowering the oxidation reaction rate of the repair layer and improving heat exchange properties when the elastic crack repair agent is applied to the crack site of the concrete structure.
여기서, 메틸디에틸아민은, 1-메톡시-4-페닐싸이클로헥산 100 중량부를 기준으로 20~40 중량부가 첨가되는데, 상기 중량부를 초과하는 경우에는 다른 조성물들과 반응시 쇼킹 현상이 발생되고, 상기 중량부를 미만하는 경우에는 산화 반응 속도가 빨라지게 되어 산화 방지 효과 및 열교환성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 범위의 중량부가 유지되는 것이 바람직하다.Here, 20 to 40 parts by weight of methyldiethylamine is added based on 100 parts by weight of 1-methoxy-4-phenylcyclohexane. When the amount is less than the above weight part, the oxidation reaction rate is accelerated, and there is a problem in that the oxidation prevention effect and heat exchange property are deteriorated.
탄산칼슘은, 콘크리트 구조물의 균열 부위에 상기 탄성 균열 보수제의 시공시 보수층의 두께를 확보하기 위한 기능을 제공한다.Calcium carbonate provides a function for securing the thickness of the repair layer during the construction of the elastic crack repair agent at the crack site of the concrete structure.
여기서, 탄산칼슘은, 1-메톡시-4-페닐싸이클로헥산 100 중량부를 기준으로 10~30 중량부가 첨가되는데, 상기 중량부를 초과하는 경우에는 다른 조성물들과 균일한 혼합이 이루어지지 않아 각 조성물들의 물성 특성이 저하되고, 상기 중량부를 미만하는 경우에는 보수층의 두께 확보가 어려워 시공성과 작업성 및 기계적 특성도 저하되는 문제점이 있으므로, 상기와 같은 한정된 범위의 중량부가 유지되는 것이 바람직하다.Here, 10 to 30 parts by weight of calcium carbonate is added based on 100 parts by weight of 1-methoxy-4-phenylcyclohexane. If the physical properties are lowered, and when the amount is less than the above weight part, it is difficult to secure the thickness of the repair layer, and there is a problem in that workability, workability and mechanical properties are also deteriorated.
탈크는, 콘크리트 구조물의 균열 부위에 상기 탄성 균열 보수제의 시공시 보수층에 고형분을 제공한다.The talc provides a solid content to the repair layer when the elastic crack repair agent is applied to the crack site of the concrete structure.
여기서, 탈크는, 1-메톡시-4-페닐싸이클로헥산 100 중량부를 기준으로 5~15 중량부가 첨가되는데, 상기 중량부를 초과하는 경우에는 점도가 높아지고 물리적 특성이 오히려 저하되며, 상기 중량부를 미만하는 경우에는 고형분 함량이 적어 보수층의 두께 확보 불가능 및 균열 내부 침투성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 범위의 중량부가 유지되는 것이 바람직하다.Here, talc is added in 5 to 15 parts by weight based on 100 parts by weight of 1-methoxy-4-phenylcyclohexane, and when it exceeds the above parts by weight, the viscosity increases and the physical properties are rather deteriorated, and less than the above parts by weight In this case, since the solid content is small, it is impossible to secure the thickness of the water-retaining layer, and there are problems in that permeability inside cracks is lowered, it is preferable to maintain the weight part in the limited range as described above.

It is desirable that the stirring speed in the same limited range be maintained.
또한, 상기 조성물이 교반되는 시간을 5~6시간으로 한정하는 것은, 교반 시간이 상기 시간보다 짧으면 팽윤이 잘 안되고, 교반 시간이 상기 시간보다 길면 고증점이 되는 문제점이 있으므로, 상기와 같은 한정된 범위의 교반 시간이 유지되는 것이 바람직하다.In addition, limiting the time the composition is stirred to 5 to 6 hours is, if the stirring time is shorter than the above time, the swelling is not good, and if the stirring time is longer than the above time, there is a problem of high viscosity. It is preferred that the stirring time be maintained.
