Description
본 발명은 수성 발수제 제조방법 및 이를 이용한 시공 방법에 관한 것으로서, 보다 상세하게는, 증류수를 소정 온도로 가열한 후 소정 회전수로 교반하면서 디하이드로테트라메틸디실록산, 이소프로필브로마이드, 4-메틸-1-펜탄올, 4-클로로-1-뷰탄올, 1-옥탄올, 벤즈아미드 및 펜탄아미드를 첨가시켜 수성 발수제를 제조한 후 구조물의 벽면에 분사 또는 도포되어 우수한 내구성을 가지도록 할 수 있는 내구성이 우수한 수성 발수제 제조방법 및 이를 이용한 시공 방법에 관한 것이다.The present invention relates to a method for manufacturing an aqueous water repellent and a construction method using the same, and more particularly, to dihydrotetramethyldisiloxane, isopropyl bromide, 4-methyl- 1-pentanol, 4-chloro-1-butanol, 1-octanol, benzamide and pentanamide are added to prepare a water-based water repellent, and then sprayed or applied to the wall of the structure to ensure excellent durability. It relates to a method for manufacturing this excellent water-based water repellent and a construction method using the same.
발수제는 오늘날 건축재료로서 중요한 부분을 차지하고 있는 콘크리트, 벽돌, 타일등의외부를 물로부터 보호하는 중요한 역할을 한다. 콘크리트, 벽돌, 타이들은 미세한 구멍들을 많이 가지고 있기 때문에 쉽게 수분이 흡수되는 단점을 가지고 있다. 벽면에 흡수된 수분은 단열효과를 저하시키고, 팽창, 수축등으로 인하여 벽면을 갈라지게 하거나 타일과 같은 외장재를 벽면으로부터 떨어뜨릴 뿐 아니라 얼룩을 만들어 외관을 해치고, 내부의 철분을 건축물의 수명을 단축시키기도 한다. 따라서 이러한 문제점을 해결하기 위해 여러가지 방법이 이용되고 있는데, 그 중 하나가 벽면을 발수제로 처리하는 것이다.Water repellents play an important role in protecting the exterior of concrete, bricks, tiles, etc., which are an important part of today's building materials, from water. Concrete, brick, and tie have a lot of micro-holes, so moisture is easily absorbed. Moisture absorbed by the wall reduces the insulation effect, cracks the wall due to expansion or contraction, or makes exterior materials such as tiles fall from the wall, as well as making stains and damaging the exterior, and shortening the lifespan of the building by using the iron inside. also do it Therefore, various methods have been used to solve this problem, and one of them is to treat the wall surface with a water repellent agent.
종래 발수제로는 기름, 왁스, 비누, 수지, 유기규소 화합물들을 사용하여 이를 붓이나 롤러, 분사등의 방법에 의해 처리하여 왔다. 그러나, 유기규소 화합물이 아닌 유기발수제인 경우, 건축재료에 피막을 형성시키면서 건축재료의 미세한 구멍들을 막아버려 통기성을 저하시키므로 건축물의 외기에 대한 적응을 어렵게 하며, 색상과 같은 외관에 변화를 준다. 그러나 유기규소계 발수제는 아주 묽은 용액으로 처리해도 효과가 좋으므로 색상에 변화를 주지않고 건축재료와 화학적인 결합을 함으로써 반영구적으로 발수 효과를 얻을 수 있다.Conventionally, oil, wax, soap, resin, and organosilicon compounds are used as water repellents, and they have been treated by methods such as brushes, rollers, and spraying. However, in the case of an organic water repellent rather than an organosilicon compound, it forms a film on the building material and blocks fine holes in the building material, thereby reducing air permeability, making it difficult to adapt to the outside air of the building and changing the appearance such as color. However, since the organosilicon-based water repellent is effective even when treated with a very dilute solution, it is possible to obtain a semi-permanent water repellent effect by chemically bonding with the building material without changing the color.
유기규소계 발수제는 유기발수제처럼 건축재의 미세한 구멍을 막음으로서 발수효과를 나타내는 것이 아니고 극히 적은양이 구멍 깊숙히 침투하여 건축재와 반응함으로써 매우 엷은 피막을 형성하여 발수효과를 내게하는 것이다. 그러므로 액체 상태의 물은 스며들지 못하나 수증기나 기체는 통과시키기 때문에 건축재의 호흡작용에 지장을 주지 않는다.Organosilicon-based water repellents do not show water repellency by blocking minute holes in building materials like organic water repellents, but a very small amount penetrates deep into the pores and reacts with building materials to form a very thin film to give water repellency. Therefore, liquid water does not permeate, but water vapor or gas passes through, so it does not interfere with the respiration of building materials.
그러나 이러한 종래의 발수제들은 내구성이 저조하여 시공후 1년 정도 시간이 지나면 발수력이 현저히 저하되는 문제점이 있다. However, these conventional water repellents have a problem in that the durability is low, and the water repellency is significantly lowered after about one year after construction.

이하, 본 발명의 바람직한 실시예에 대하여 상세히 설명하기로 한다. Hereinafter, preferred embodiments of the present invention will be described in detail.
본 발명의 바람직한 실시예에 따른 내구성이 우수한 수성 발수제는, 기본적으로, 증류수를 소정 온도로 가열한 후 소정 회전수로 교반하면서 디하이드로테트라메틸디실록산, 이소프로필브로마이드, 4-메틸-1-펜탄올, 4-클로로-1-뷰탄올, 1-옥탄올, 벤즈아미드 및 펜탄아미드를 첨가시키는 것을 통해 제조되며, 구조물의 벽면에 분사 또는 도포되어 우수한 내구성을 제공한다.The water-based water repellent having excellent durability according to a preferred embodiment of the present invention is basically dihydrotetramethyldisiloxane, isopropyl bromide, 4-methyl-1-pentane while heating distilled water to a predetermined temperature and stirring at a predetermined number of revolutions. It is prepared by adding ol, 4-chloro-1-butanol, 1-octanol, benzamide and pentanamide, and is sprayed or applied to the wall surface of the structure to provide excellent durability.
보다 구체적으로, 본 발명의 바람직한 실시예에 따른 내구성이 우수한 수성 발수제 제조방법은, 증류수 100 중량부를 70~80 ℃로 가열한 후 1000~1200 rpm으로 교반하면서 디하이드로테트라메틸디실록산 70~90 중량부, 이소프로필브로마이드 60~80 중량부, 4-메틸-1-펜탄올 50~70 중량부, 4-클로로-1-뷰탄올 40~60 중량부, 1-옥탄올 30~50 중량부, 벤즈아미드 20~40 중량부 및 펜탄아미드 10~30 중량부가 첨가되는 단계를 포함한다.More specifically, in the method for producing a water-based water repellent having excellent durability according to a preferred embodiment of the present invention, 100 parts by weight of distilled water is heated to 70 to 80 ° C., and then stirred at 1000 to 1200 rpm by 70 to 90 weight of dihydrotetramethyldisiloxane parts, isopropyl bromide 60-80 parts by weight, 4-methyl-1-pentanol 50-70 parts by weight, 4-chloro-1-butanol 40-60 parts by weight, 1-octanol 30-50 parts by weight, benz and adding 20-40 parts by weight of amide and 10-30 parts by weight of pentanamide.
또한, 본 발명의 바람직한 실시예에 따른 내구성이 우수한 수성 발수제를 이용한 시공 방법은, 상기와 같이 수성 발수제가 제조되는 단계와, 상기 제조된 수성 발수제가 바탕처리된 구조물의 적벽돌이나 콘크리트 등의 벽면에 0.3kg/m2 용량으로 스프레이되거나 롤러를 통해 1회 도포되어 발수층을 형성시키는 단계 등을 포함한다.In addition, the construction method using a water-based water-repellent agent having excellent durability according to a preferred embodiment of the present invention includes the steps of preparing the water-based water-repellent agent as described above, and wall surfaces such as red bricks or concrete of the structure on which the water-based water repellent agent is ground-treated. It is sprayed at a capacity of 0.3 kg/m2 or applied once through a roller to form a water-repellent layer.
증류수는, 상기 조성물들의 혼합 교반을 통해 제조되는 수성 발수제가 구조물의 벽면에 도포시 벽면 내부로 빠르게 확산되면서 스며들도록 하여 표면 뿐만 아니라 내부에서도 안정된 발수층을 형성하고 강도가 증강되도록 한다.Distilled water allows the water-based water repellent prepared by mixing and stirring the compositions to quickly diffuse and permeate into the wall surface when applied to the wall surface of the structure, thereby forming a stable water repellent layer on the surface as well as on the inside and enhancing the strength.
여기서, 증류수는, 상기 조성물들에 대하여 100 중량부가 첨가되는데, 상기 중량부를 초과하는 경우에는 발수 기능을 제공하는 다른 조성물들이 묽게 되어 발수 기능이 저하 되고, 상기 중량부에 미만하는경우에는 벽면의 내부로 확산되지 못하고 흘러 내리게 되어 내구성과 작업성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 좋다.Here, 100 parts by weight of distilled water is added with respect to the above-mentioned compositions, and when it exceeds the above parts by weight, other compositions providing a water-repellent function are diluted and the water-repellent function is reduced. Since there is a problem in that durability and workability are deteriorated because it is not diffused and flows down, it is preferable to have a limited weight part as described above.
