Description
본 발명은 건축물의 외벽에 도포되는 수성도료의 오염을 방지하기 위한 조성물 및 그 조성물을 제조하는 방법에 관한 것이다. The present invention relates to a composition for preventing contamination of an aqueous paint applied to the outer wall of a building and a method for producing the composition.
일반적으로 다양한 건축물 및 토목 구조물에는 그 외관을 보호함은 물론 미관을 위해 도료가 도포된다. 최근 환경학적 요인으로 인해 건축물 및 토목 구조물에 사용하는 도료는 유기용제를 용매로 사용하는 도료보다는 물을 용매로 하는 수계 도료를 주로 사용하고 있다.In general, various buildings and civil structures are coated with paint to protect their appearance as well as aesthetics. Recently, due to environmental factors, paints used in buildings and civil engineering structures mainly use water-based paints rather than organic solvents as paints.
이와 같은 수계 도료로서, 아크릴 에멀젼이 건축용 외벽 도료 분야에서 널리 사용되어 왔다. 그러나, 최근에는 다양한 소비자의 욕구에 부응하기 위해 더욱 차별화된 고기능성 도료에 대한 연구 및 개발이 활발히 이루어지고 있다. 이와 같은 연구 및 개발의 결과로서 건물 외벽의 보호기능 측면에서 재 도장기간을 길게 해주며, 오염물질의 부착을 방지하여 건축물의 미려한 외관을 장시간 보장해 주는 건축용 수성 외벽 도료용 오염 방지제가 있다As such water-based paints, acrylic emulsions have been widely used in the field of exterior wall paint for construction. However, in recent years, research and development for more differentiated high functional paints are actively conducted to meet the needs of various consumers. As a result of such research and development, there is an anti-fouling agent for water-based exterior coatings for building that prolongs the repainting period in terms of the protection function of the building's exterior wall and prevents the attachment of pollutants to guarantee the beautiful appearance of the building for a long time.
예컨대, 산업이 발달함에 따라 도시주변에는 매연이나 배기가스 등의 대기오염에 의해 건축물의 오염이 심각해지는 추세에 있다. 즉, 복합열화, 복합오염, 공해 등으로 대표되는 환경 하에서는 소기의 미관을 유지할 수 없고 단기간에 건축물이 오염되는 문제가 있는 것이다.For example, as the industry develops, there is a tendency for pollution of buildings due to air pollution such as soot and exhaust gas. That is, under the environment represented by complex deterioration, complex pollution, pollution, etc., there is a problem that the desired beauty cannot be maintained and the building is contaminated in a short time.
또한, 주택, 아파트, 맨션, 오피스 빌딩 및 상업 빌딩 등의 건축물의 경우에는 외부의 오염으로 인해 자산가치가 하락함은 물론 기업이미지의 실추를 초래하고 있고, 고속도로, 교량, 항만시설 등 공공 구조물의 경우에는 지역 주민의 주거환경 및 생활환경에 악영향을 주는 문제점이 초래되고 있다.In addition, in the case of buildings such as houses, apartments, mansions, office buildings, and commercial buildings, the value of assets decreases due to external pollution and causes the loss of corporate image.In addition, public structures such as highways, bridges, and port facilities In this case, there are problems that adversely affect the living environment and living environment of local residents.
더욱이, 환경 보호의 중요성에 대한 관심이 최고조에 달하고 있고, 자원부족에 대한 우려가 높아지고 있는 시기이며, 이에 더하여 건축물 외벽의 수명에 대한 관심이 고조되고 있으며, 이로 인해 건축물 외벽의 도장 수명을 길게 해 주는 내오염성 및 고내후성을 동시에 제공하는 오염 방지제의 개발이 절실히 요구되고 있는 실정에 있다.Moreover, interest in the importance of environmental protection is peaking, and there is a growing concern about the lack of resources. In addition, there is a growing interest in the lifespan of building exterior walls. The state is in urgent need for the development of anti-pollution agents that provide both pollution and high weather resistance.
이와 같은 복합오염물은 주로 자동차 배기가스 또는 타이어와 도로의 마찰에 의해 발생되는 물질 등에 기인하며 일명 친유성 오염 물질이라고 칭하고 있다. 따라서 내오염성은 친유성 오염 물질이 부착하기 어려운 특성뿐만 아니라 표면에 부착된 오염 물질이 비로 인해 침착되지 않는 특성을 지녀야 한다. 오염물질의 부착을 방지하거나 부착된 오염물질이 내부로 침투되지 않도록 하기 위해서는 도막을 치밀하게 설계하여야 하며, 표면에 부착된 친유성 오염 물질이 빗물에 의해 쉽게 제거되도록 하기 위해서는 친수성 도막 표면을 형성하는 기술이 요구되는 것이다. Such complex pollutants are mainly due to substances generated by friction of automobile exhaust gas or tires and roads, and are called lipophilic pollutants. Therefore, the fouling resistance should not only be difficult to adhere to lipophilic contaminants but also have a property that contaminants attached to the surface are not deposited by rain. To prevent the adhesion of contaminants or to prevent the contaminants from penetrating into the interior, the coatings must be designed carefully. To ensure that the lipophilic contaminants attached to the surface are easily removed by rain water, Skill is required.
이에 본 발명은 상술된 문제점 및 과제를 해결하기 위한 것으로서, 본 발명의 목적은 내오염성 및 내후성이 향상된 건축물 외벽 수성도료용 오염방지제 조성물을 제공하는데 있다.Accordingly, the present invention is to solve the problems and problems described above, an object of the present invention is to provide an antifouling composition for water-based coatings for building exterior walls with improved pollution resistance and weather resistance.

In addition, the content of the polyhydromethylsiloxane used in the antifouling composition for building exterior water coating according to the present invention is preferably set to 40 to 50 parts by weight based on 100 parts by weight of distilled water. Here, if the content of polyhydromethylsiloxane is less than 40 parts by weight, the water repellency is lowered, whereas if it exceeds 50 parts by weight, the specific gravity is increased to reduce the storage stability. On the other hand, the content of polyhydromethylsiloxane is most preferably 45 parts by weight.
