일반적으로 콘크리트 구조물의 수분에 의한 부식이나 파손 등을 방지하기 위해서는 콘크리트 구조물 표면에 방수 또는 방식 처리가 요구된다.In general, in order to prevent corrosion or damage caused by moisture of a concrete structure, waterproofing or anticorrosive treatment is required on the surface of the concrete structure.
이를 위하여, 현재 콘크리트 구조물의 건축 공사시 사용되고 있는 시멘트 방수재로는, 등록특허 제10-0566155호, 등록특허 제10-0973984호, 등록특허 제10-1293448호 및 특허공보 특1996-0006222호 등에 개시된 바와 같이, 다양한 것들이 있으나, 대부분 표면이 매우 거칠게 시공되는 콘크리트 구조물에 대해 충분한 방수 효과를 나타내고 있지 못하는 실정이다.To this end, as a cement waterproofing material currently used in the construction of concrete structures, it is disclosed in Patent Registration No. 10-0566155, Registration Patent No. 10-0973984, Registration Patent No. 10-1293448, and Patent Publication No. 1996-0006222. As shown, there are various types, but most of them do not exhibit a sufficient waterproofing effect for a concrete structure having a very rough surface.
예를 들면, 등록특허 제10-0566155호와 등록특허 제10-0973984호 등에 개시된 바와 같은 시멘트 방수재는, 알콕시실란 화합물 및 오르가노실록산 화합물 또는 그 축합물로부터 구성되는 폴리실록산을 수성매체로 분산, 유화, 용해한 실리콘변성아크릴계 투명도료를 제공하거나 또는, 알킬알콕시실란과 알킬알콕시실란 올리고머를 동시에 사용하는 수성 에멀젼 조성물을 제공하고 있으나, 상기와 같이 각종 지방산을 주원료로 하는 시멘트 방수재의 경우, 방수성은 우수하지만 콘크리트 표면 즉, 모체와의 접착력이 부족하여 시간이 경과되면 부풀음 현상이 나타나는 문제점이 있다.For example, in the cement waterproofing material disclosed in Patent Registration Nos. 10-0566155 and 10-0973984, etc., polysiloxane composed of an alkoxysilane compound and an organosiloxane compound or a condensate thereof is dispersed and emulsified in an aqueous medium. , a silicone-modified acrylic transparent paint dissolved therein, or an aqueous emulsion composition using an alkylalkoxysilane and an alkylalkoxysilane oligomer at the same time. There is a problem in that the concrete surface, that is, the adhesion to the parent body is insufficient, and the swelling phenomenon appears over time.
또한, 등록특허 제10-1293448호 등에 개시된 바와 같은 시멘트 방수재는, 테트라에톡시오로스실란과 메틸트리메톡시실란을 에폭시 분자 내에 도입한 에폭시 수지 조성물을 제공하고 있으나, 상기와 같이 합성수지와 파라핀 등을 주원료로 하는 시멘트 방수재의 경우, 모체와의 접착력과 방수성은 지방산을 주재료로 하는 시멘트 방수재에 비하여 우수한 특성을 가지지만, 강도가 부족하여 약간의 충격에도 방수층에 균열이 발생되는 문제점이 있다.In addition, the cement waterproofing material as disclosed in Korean Patent Registration No. 10-1293448, etc. provides an epoxy resin composition in which tetraethoxylossilane and methyltrimethoxysilane are introduced into the epoxy molecule, but as described above, synthetic resin, paraffin, etc. In the case of a cement waterproofing material using as a main raw material, adhesive strength and waterproofing properties with the parent body are superior to those of a cement waterproofing material containing fatty acids as the main material, but there is a problem in that the waterproofing layer is cracked even with a slight impact due to lack of strength.
또한, 특허공보 특1996-0006222호 등에 개시된 바와 같은 시멘트 방수재는, 시멘트에 유리분만, 모래, 계면활성제 및 규산소다 등이 혼합되는 조성물을 제공하고 있으나, 상기와 같이 각종 무기질 계통의 시멘트를 주원료로 하는 시멘트 방수재의 경우, 대부분 내마모성과 내후성이 부족하여 산성비에 취약한 문제점이 있다.In addition, the cement waterproofing material as disclosed in Patent Publication No. 1996-0006222, etc. provides a composition in which cement is mixed with glass powder, sand, a surfactant and sodium silicate, but as described above, various inorganic cements are used as the main raw material. In the case of cement waterproofing materials, most of them lack abrasion resistance and weather resistance, so they are vulnerable to acid rain.
또한, 종래의 시멘트 방수재는, 일반적으로 경화제의 점도가 높아 시멘트 중의 칼슘과 급속히 반응하게 되고 이에, 단시간에 시멘트와 함께 겔화가 이루어지기 때문에, 공극의 표면에만 침투가 된 상태에서 결정이 형성되어 용탈, 내구성저하, 차수성능저하 등이 발생되는 문제점이 있다.In addition, the conventional cement waterproofing material generally has a high viscosity of the curing agent, so it reacts rapidly with calcium in the cement, and thus, gels with the cement in a short time. , there is a problem in that durability, water-repellent performance, and the like occur.
