Description
본 발명은 분말형 시멘트 방수제에 관한 것으로서, 보다 상세하게는 에틸렌/비닐라우레이트/비닐클로라이드 삼원 공중합체와 아크릴레이트 공중합체로 구성하여 접착력이 증대되고 흡수비 및 투수비가 감소되며 경화시간이 단축되는 분말형 시멘트 방수제에 관한 것이다. The present invention relates to a powder-type cement waterproofing agent, and more specifically, composed of ethylene / vinyllaurate / vinylchloride terpolymer and acrylate copolymer to increase adhesion, decrease absorption and permeability ratio, and shorten curing time. A powdery cement waterproofing agent.
일반적으로 건물의 옥상이나 기타 토목 구조물에서는 습기가 침투하거나 수압의 영향을 받을 수 있으므로 그 콘크리트 표면의 방수를 필요로 하고 있다. 이 같은 종래의 방수제로는 무기질 도포형 시멘트 방수제, 침투형 방수제, 규질산계 방수제, 분말형 방수제 등이 있다. In general, the roof of a building or other civil structures need to waterproof the concrete surface because moisture can penetrate or be affected by water pressure. Such conventional waterproofing agents include inorganic coating type cement waterproofing agents, penetration type waterproofing agents, silicic acid based waterproofing agents, powder type waterproofing agents and the like.
이와 같은 종래의 방수제 중 무기질계 침투성 방수제는 사용시 시멘트와 물에 의해 경화된 후 시멘트의 수화시 칼슘하이드록사이드와 같은 염이 발생되며, 또한 실리카 성분이 시멘트 수화시 발생한 염과 반응하여 Cao·Sio3 와 같은 불용성 결정체가 생성된다. 이에 따라 불용성 결정물이 시멘트 공극 사이를 채우게 되어 수밀성이 제공되어 방수되는 것이다.Among these conventional waterproofing agents, the inorganic permeable waterproofing agent is cured by cement and water in use, and then salts such as calcium hydroxide are generated when the cement is hydrated, and the silica component reacts with the salt generated when the cement is hydrated. Insoluble crystals such as 3 are produced. As a result, insoluble crystals are filled between the cement voids, thereby providing watertightness and waterproofing.
그러나 이와 같은 무기질계 침투성 방수제는 다소의 문제점이 초래되는 것으로 나타났다. 즉, 과수압이 가해지지 않는 정상적인 상태의 콘크리트 구조물의 경우에는 우수한 방수성이 제공되지만 수압이 강하게 작용하는 지하실과 같은 구조물의 형성시에는 그 방수 공사시 접착력이 약하고 물 흡수비와 투수비가 높아 수압에 견디지 못하므로 누수가 발생되고 박리가 초래되는 문제점이 있다.However, the inorganic permeable waterproofing agent appeared to cause some problems. In other words, in the case of a concrete structure in a normal state that is not subjected to overwater pressure, excellent waterproofing is provided, but when a structure such as a cellar with strong water pressure is formed, the adhesion is weak during the waterproofing work, and the water absorption ratio and permeability ratio are high. There is a problem that can not withstand leakage occurs and peeling occurs.
더욱이, 종래의 시멘트계 분말형 방수제는 지하 구조물 등 수압의 영향을 받는 부위에 주로 사용되고 있으나 지하 3층 이상, 즉 3kgf/cm2 이상의 압력을 받는 곳에서는 들뜸 현상과 같이 모체인 지하 구조물로부터 방수층이 형성 되기전 생기는 수압의 영향으로 방수층 박리현상의 발생 및 방수층의 취약 부위가 발생되는 문제점이 있다.Moreover, the conventional cement-based waterproofing agent is mainly used in the area affected by hydraulic pressure, such as underground structures, but the waterproof layer is formed from the basement underground structure like the floating phenomenon in the place where the pressure is more than 3 stories underground, that is, 3kgf / cm 2 or more. There is a problem in that the waterproofing layer peeling phenomenon and the weak part of the waterproofing layer is generated under the influence of the water pressure generated before.
이에 본 발명은 상술된 문제점들을 해결하기 위해 발명된 것으로서, 본 발명의 목적은 접착력이 향상되고 흡수비와 투수비가 감소되는 분말형 시멘트 방수제를 제공하는데 있다.Accordingly, the present invention has been invented to solve the above-mentioned problems, an object of the present invention is to provide a powder-type cement waterproofing agent is improved adhesion and reduced absorption and permeability ratio.
