It can be called a concrete surface treatment method that can be expected.
일반적으로 콘크리트구조물은 거푸집 또는 금형에 의하여 성형되기 때문에 표면이 거칠고 미려하지 못하며 또한 외부적인 조건에 의하여 열화되므로 그 수명이 단축된다. 좀더 구체적으로는 온도변화, 계절변화에 따른 극심한 온도차이, 동결융해, 습도대기조건과 같은 환경적인 요인과 산알카리 화학약품, 가스 등에 의해 구조물의 표면이 손상되거나 성능이 저하되게 된다.In general, the concrete structure is formed by the formwork or mold, the surface is rough and not beautiful, and also deteriorated by external conditions, the life is shortened. More specifically, the surface of the structure may be damaged or degraded by environmental factors such as temperature change, extreme temperature difference due to seasonal change, freezing thawing, atmospheric humidity, acid alkali chemicals and gas.
이와 같이 시멘트구조물의 장식효과를 높히고 콘크리트구조물의 성능을 지속적으로 유지함은 물론 도장된 시멘트구조물에서 없는 기능을 보충하거나 강화하기 위해 여러가지 목적으로 표면처리를 행하게되는 종래기술들이 소개되고 있다.As such, prior arts have been introduced to enhance the decorative effect of cement structures and maintain the performance of concrete structures, as well as to perform surface treatment for various purposes in order to supplement or reinforce functions not present in the painted cement structures.

다른 종래기술로서 국내공개특허공보(공개번호 제10-2004-14718호)에는 "콘크리트표면 보호용 무기질계 표면처리재료 조성물"에 관한 기술이 소개되고 있다. 기술의 내용은 시멘트 30~40중량%, 고로슬래그 20~30중량%, 실리카흄 3~7중량%, 스티렌부타디엔 고무계폴리머 10~15중량%, 규사 10~15중량%, 혼화제 10~20중량%으로 조성되는 무기질계 표면처리재료 조성물에 관한 것이다. 이와 같은 콘크리트표면 보호용표면처리재 조성물은 통상의 콘크리트조성물같이 시멘트, 고로슬래그, 실리카흄, 규사 등 통상의 수경화반응물질에 폴리머시멘트로 널리 사용되는 SBR폴리머를 첨가한 통상의 폴리머시멘트 콘크리트조성물로 여기에 실리카흄을 첨가하여 콘크리트구조체를 성형시에는 강도의 향상을 기대할 수 있으나 통상의 콘크리트구조체의 표면처리제로 도료층 형성정도의 박막으로 코팅할 경우에는 콘크리트구조체의 조성과 표면처리제의 조성차이 및 양생중 바탕콘크리트구조체로부터 수분의 흡수 등으로 양생에 의한 문제점 발생으로 보호기능을 갖는 표면처리제로서는 그 효과를 크게 기대하기 어려운 표면처리재조성물이라 할 수 있다.As another conventional technology, Korean Patent Publication (Publication No. 10-2004-14718) discloses a technology related to an inorganic surface treatment material composition for concrete surface protection. The contents of the technology are 30 to 40% by weight cement, 20 to 30% by weight blast furnace slag, 3 to 7% by weight silica fume, 10 to 15% by weight styrene-butadiene rubber polymer, 10 to 15% by weight of silica sand, 10 to 20% by weight admixture The present invention relates to an inorganic surface treatment material composition. The surface treatment material composition for protecting the concrete surface is a conventional polymer cement concrete composition containing SBR polymer, which is widely used as a polymer cement, in a conventional hydrocuring reaction material such as cement, blast furnace slag, silica fume, and silica sand as a conventional concrete composition. When the concrete structure is formed by adding silica fume to the concrete, the strength can be expected to be improved.However, when coating with a thin film having the same level of coating layer as the surface treatment agent of a conventional concrete structure, the composition of the concrete structure and the composition difference between the surface treatment agent and curing As a surface treatment agent having a protective function due to problems caused by curing due to absorption of moisture from the base concrete structure, it can be said that the surface treatment material composition is hardly expected to be effective.
국내등록특허공보(등록번호 제542423호)에 소개되는 "콘크리트구조물의 열화억제를 위한 침투성 방수공법", 국내등록특허공보(등록번호 제565268호)에 소개되는 "콘크리트구조물의 중성화방지를 위한 표면보호제의 제조방법 및 이를 이용한 신규건축물과 보수건축물의 중성화 방지공법" 그리고 국내등록특허공보(등록번호 제661210호)에 나타나 있는 "침투 발수기능과 방수성을 가지는 실리콘레진 에멀젼 피막제 및 그 제조방법"에 나타나 있는 바와 같이 실리콘계 침투성 발수제를 콘크리트 구조물이나 석재표면 조직내에 침투처리하는 공법이라 할 수 있다."Permeable waterproofing method for suppressing deterioration of concrete structure" introduced in Korean registered patent publication No. 542423; Surface for preventing neutralization of concrete structure introduced in Korean registered patent publication No. 565268 Method of manufacturing the protective agent and the neutralization prevention method of new and repaired buildings using the same, and "Silicone resin emulsion coating agent having a water-infiltrating and waterproofing property and its manufacturing method" shown in Korean Patent Publication (Registration No. 661210). As shown, the silicone-based permeable water repellent may be referred to as a method of penetrating into a concrete structure or stone surface structure.
그러나 상기와 같은 실리콘계 발수제를 이용하는 표면처리공법은 실리콘계 발수제가 발수성이 우수하고 석재표면이나 구조물에 침투성이 강하여 외부로부터 수분과 염화물의 이온침투를 효과적으로 막아주기 때문에 구조물의 동결융해에 대한 저항성 철근부식을 방지하는 효과가 있다 할 것이나 실리콘계 발수제가 형성하는 피막은 멤브레인형태로 기밀성이 좋지 않으므로 콘크리트구조물의 중성화에 대한 저항성은 크게 기대할 수 없으며 또한 실리콘계 발수제는 휘발성이 있으며 자외선에 의한 열화가 발생하여 도포 초기에는 우수한 발수력을 발휘하지만 시간경과에 따라 그 효과가 크게 저하되므로 내구성이 크게 떨어진다.
However, the surface treatment method using the silicone-based water repellent is excellent in water repellency and permeability to the stone surface or structure, which effectively prevents the penetration of water and chloride ions from the outside. However, since the film formed by the silicone-based water-repellent agent has a poor airtightness in the form of a membrane, the resistance to neutralization of the concrete structure cannot be greatly expected.Since the silicone-based water-repellent agent is volatile and deteriorated by ultraviolet rays, Excellent water repellency, but the effect is greatly reduced over time, so durability is greatly reduced.

It was possible to achieve the object of the present invention by providing a concrete surface treatment method by a multi-color paint to be dried for 2-3 hours by maintaining a humidity of 50%.
상기 발명에서 하도조성물에 프라이머의 사용은 콘크리트구조물의 표면의 무수한 미세요철과 간극을 매워 표면평활성을 좋게하므로서 도장성을 향상시킬 수 있고 또한 방수성과 내약품성을 제고시킴에 있으며 실란카프링제(silancouplingagent)는 콘크리트표면층과 하도층과의 강력한 접착력을 갖게함과 동시에 중도층과도 강력한 접착력을 가지므로서 층간에 박리현상이 발생하지 않는다. 여기에서 실란카프링제는 아미노기, 에폭시기, 2중결합의 관능기를 가지고 있어 유기재료(합성수지)와 무기질재료(유리, 모래, 금속)를 강력하게 결합시킬 수 있으며 수지자체에 첨가하여도 수지자체의 강도가 개선된다.In the present invention, the use of a primer in the undercoat composition can improve the paintability by filling the gaps with numerous uneven irregularities of the surface of the concrete structure, thereby improving the surface smoothness, and also improving the waterproofing and chemical resistance, and the silane capping agent (silancouplingagent) Has strong adhesion between the concrete surface layer and the undercoating layer, and also has strong adhesion with the intermediate layer, so that peeling does not occur between layers. Here, the silane capping agent has an amino group, an epoxy group, and a double bond functional group, so that the organic material (synthetic resin) and the inorganic material (glass, sand, and metal) can be strongly bound, and the strength of the resin itself even when added to the resin itself. Is improved.
중도용 도료조성물은 착색아크릴폴리머는 프레크(flecks)상의 작은편으로서 중도도료의 전색제(vihicle)로서 사용되며 이 수지는 비결정성 고분자물질이지만 아크릴산 에스테르의 비교적 극성기를 가지고 있기 때문에 접착성과 점성이 강한 성질을 가지고 있으며 광학적으로 대단히 아름다운 감각을 주게되며 염료, 안료와 같은 컬러에 의한 염색착색이 용이한 합성수지라 할 수 있고 극성의 원자단을 함유하고 있기 때문에 도막의 인장강도 및 충격강도가 좋아 균열이 발생하지 않으며 백화크레이징현상을 일으키지 않는 특징에 있어 라텍스도료로 널리 이용되고 있는 수지라 할 수 있다.The intermediate coating composition is colored acrylic polymer, which is a small piece on the flecks, and is used as a vehicle for the intermediate coating. This resin is an amorphous polymer material, but it has a relatively polar group of acrylic ester, so it has high adhesiveness and viscosity. It is a synthetic resin that has properties and gives optically beautiful senses and is easy to dye and color by colors such as dyes and pigments. Because it contains polar atomic groups, cracks occur because of excellent tensile strength and impact strength of coating film.
