Description
본 발명은 균열 부위의 보수를 위한 탄성 퍼티재 조성물, 이를 위한 전용 프라이머 조성물 및 이들을 이용한 시공방법에 관한 것이다.The present invention relates to an elastic putty material composition for repairing cracks, a dedicated primer composition for the same, and a construction method using the same.
일반적으로 콘크리트로 시공된 건물, 도로, 주차장 등의 시설은 시간이 경과하면서 균열이 발생하게 된다. 균열은 미관상의 문제 뿐만 아니라 시설의 노후화와 파손을 가속화하고 붕괴를 유발할 수 있으므로, 주기적인 보수가 요구된다.In general, facilities such as buildings, roads, and parking lots made of concrete develop cracks over time. Cracks not only cause aesthetic problems, but also accelerate the deterioration and damage of facilities and can cause collapse, so periodic repairs are required.
이러한 콘크리트 시설의 균열 보수에서 일반적으로 사용되는 보수제는 대부분 MMA(Methyl Methacrylate)를 기반으로 하는 아크릴계 보수제이다. 그러나 MMA는 인체 유해성, 역한 냄새 등의 문제가 있다.The repair agents commonly used to repair cracks in these concrete facilities are mostly acrylic repair agents based on MMA (Methyl Methacrylate). However, MMA has problems such as being harmful to the human body and having a foul smell.
또한, 종래 보수제의 경우 보수된 부분이 콘크리트 구조물에서 요구되는 수밀성을 통한 방수성능, 강도, 각종 열화인자에 대한 내구성능 등의 기본 물성을 충분히 갖추지 못한 경우가 많다는 문제가 있다. 이러한 문제는 시설물의 안전성을 떨어뜨리고, 재보수로 이어져 공사기간과 비용을 추가로 발생시키게 된다. In addition, in the case of conventional repair agents, there is a problem that the repaired part often does not have sufficient basic physical properties such as waterproofing performance through watertightness, strength, and durability against various deterioration factors required for concrete structures. These problems reduce the safety of facilities and lead to re-renovation, resulting in additional construction time and costs.
등록특허 제10-1500958호는 아크릴계 보수제를 이용한 콘크리트 보수에 관한 것으로, 저온에서 강도 발현이 빠르고 강도 및 내구성이 증진되고, 신속성 및 작업성이 개선된 초속경 고분자계 콘크리트 보수재의 제조방법을 기재하고 있다. 그러나 MMA를 주성분으로 하는 아크릴계 보수제로, MMA가 갖는 인체 유해성, 역한 냄새 등의 한계가 있다.Registered Patent No. 10-1500958 relates to concrete repair using an acrylic repair agent, and describes a method of manufacturing an ultra-fast hardening polymer-based concrete repair material with rapid strength development at low temperatures, improved strength and durability, and improved speed and workability. there is. However, as an acrylic water repair agent containing MMA as its main ingredient, MMA has limitations such as being harmful to the human body and having a foul odor.
등록특허 제10-2167528호는 속경형 콘크리트 균열 보수용 아크릴 올리고머와 단량체 및 착색제를 이용한 균열 실링제로서, 기존 아크릴계 보수제의 역한 냄새와 다량의 인체 유해 물질 배출에 대한 문제, 라디칼 중합에 따른 산소에 의한 방해 현상, 실링제의 암색 발현에 따른 미관 저하를 개선한 균열 실링제 조성물 및 이를 이용한 균열 보수 시공 방법을 제공하고 있다. 그러나 아크릴 올리고머와 단량체가 조성물의 대부분을 차지하는 주재료이므로, 강도·내열성·내 알칼리성·자외선 저항성 등이 떨어지고, 시설물의 주재료인 콘크리트재와의 물성 차이가 커 보수 부위가 클 경우 물성 차이에 따른 2차 균열 유발과 같은 안정성 저하의 문제가 있다. Registered Patent No. 10-2167528 is a crack sealing agent using acrylic oligomer, monomer, and colorant for repairing fast-hardening concrete cracks. It has problems with the unpleasant odor of existing acrylic repair agents, the emission of a large amount of substances harmful to the human body, and the problem of oxygen due to radical polymerization. A crack sealing agent composition that improves the appearance of the sealant due to obstruction and darkening of the sealant, and a crack repair construction method using the same are provided. However, since acrylic oligomers and monomers are the main materials that make up most of the composition, the strength, heat resistance, alkali resistance, and UV resistance are low, and the difference in physical properties from concrete, which is the main material of the facility, is large, so when the repair area is large, secondary damage due to the difference in physical properties occurs. There is a problem of reduced stability, such as causing cracks.
