에너지 절감형 방수도료 조성물, 에너지 절감형 방수도막 및 이를 이용한 에너지 절감형 복합 방수공법Energy-saving waterproofing paint composition, energy-saving waterproofing coating and energy-saving composite waterproofing method using the same
본 발명은 에너지 절감형 방수도료 조성물, 에너지 절감형 방수도막 및 이를 이용한 에너지 절감형 복합 방수공법에 관한 것으로서, 좀더 상세하게는, 상도 고유의 색상을 표현하면서 더블 반사, 트리플 반사 효과로 우수한 태양광 반사효과를 부여할 수 있는 에너지 절감형 방수도료 조성물, 에너지 절감형 방수도막 및 이를 이용한 에너지 절감형 복합 방수공법에 관한 것이다. The present invention relates to an energy-saving waterproof paint composition, an energy-saving waterproof coating film, and an energy-saving composite waterproofing method using the same. It relates to an energy-saving waterproof paint composition capable of imparting a reflective effect, an energy-saving waterproof coating film, and an energy-saving composite waterproofing method using the same.
태양광 반사형 소재 중 범용적이며 경제성이 우수한 이산화티탄을 적용하여 태양광 반사형 도료로 판매하고 있으나 태양광 반사율을 90% 이상 향상시키는 것은 한계가 있다. Among the solar reflective materials, titanium dioxide, which is universal and economical, is applied and sold as a solar reflective paint, but there is a limit to improving the solar reflectance by 90% or more.
종래의 수성 방수재 상도는 주로 1액형 아크릭 타입으로 용제나 수분 증발에 의한 도막 형성이 되기에, 2액형 우레탄 타입과 같은 화학적 결합과 비교하면 부착력, 내후성, 내구성, 반사유지율 등과 같은 문제가 있다.Since the conventional water-based waterproofing topcoat is mainly a one-component acrylic type, and a coating film is formed by evaporation of solvent or moisture, there are problems such as adhesion, weather resistance, durability, and reflective retention compared to chemical bonding such as a two-component urethane type.
특히, 종래의 1액형 아크릭 타입의 수성 방수재 상도는 내구성 및 내오염성이 떨어져 초기의 반사율이 높더라도 이를 오래 유지할 수 있는 반사유지율이 떨어진다. In particular, the conventional one-component acrylic type water-based waterproofing topcoat has poor durability and stain resistance, so even if the initial reflectance is high, the reflection retention rate that can maintain it for a long time is poor.
이러한 문제점을 해결하기 위하여, 상도에 2액형 타입의 폴리우레탄계 도료를 적용해 부착성, 내후성, 내구성 등을 보완하며 차열 효과의 유지력을 증진시키고자 한 기술이 제안된 바 있다.In order to solve this problem, a technology has been proposed to improve the retention of the heat shield effect by supplementing adhesion, weather resistance, durability, etc. by applying a two-component type polyurethane paint to the top coat.
그러나, 이러한 기술들도 1차 반사와 2차 반사를 통해 반사율을 높이지만, 반사율 극복의 한계가 있으며, 특히 유색의 경우 반사율이 현저히 저하되는 문제점이 있으며, 지붕에 적용하는 도료는 백색보다 회색이나 녹색을 선호하고 있어, 다양한 색상을 구현하면서 태양광 반사율을 높이는 부분이 요구되고 있다.However, these technologies also increase reflectance through primary and secondary reflection, but there is a limit to overcoming reflectance. Since green is preferred, a part that increases the solar reflectance while implementing various colors is required.
이에, 상도 고유의 색상을 표현하면서도 우수한 태양광 반사효과를 부여할 수 있는 에너지 절감형 방수도료 조성물, 에너지 절감형 방수도막 및 이를 이용한 에너지 절감형 복합 방수공법 기술이 요구되고 있다.Accordingly, there is a need for an energy-saving waterproof paint composition, an energy-saving waterproof coating film, and an energy-saving composite waterproofing method technology using the same, which can express the unique color of the top coat and impart an excellent solar reflection effect.
본 발명은 에너지 절감형 방수도료 조성물과 반사율이 높고, 낮은 열전도율을 가지는 다층 구조의 에너지 절감형 방수도막 및 에너지 절감형 복합 방수공법을 제공하고자 한다. The present invention is to provide an energy-saving waterproof coating composition, a multi-layer energy-saving waterproof coating film having high reflectivity and low thermal conductivity, and an energy-saving composite waterproofing method.
또한, 본 발명은 상도 고유의 색상을 표현하면서도 더블 반사, 트리플 반사 효과로 우수한 태양광 반사효과를 극대화할 수 있는 에너지 절감형 방수도료 조성물, 에너지 절감형 방수도막 및 이를 이용한 에너지 절감형 복합 방수공법을 제공하고자 한다. In addition, the present invention is an energy-saving waterproof paint composition, an energy-saving waterproof coating film, and an energy-saving composite waterproofing method using the same that can maximize the excellent solar reflection effect with double reflection and triple reflection effects while expressing the unique color of the top coat. want to provide

In the waterproof paint composition for energy-saving top coating according to the present invention, when the main part is less than 3.7 or the hardener part is more than 1.0, the NCO ratio (% NCO) becomes less than 1.0, so the hardener part remains, resulting in uncured phenomenon or lack of strength. And, when the main part exceeds 3.7 or the curing agent part is less than 1.6, the NCO ratio (% NCO) becomes greater than 1.5, so the main part remains, causing problems such as deterioration of adhesion during curing.

먼저, 수계형 에멀젼 수지는 히드록실기를 함유하는 수계형 폴리아크릴레이트 에멀젼 수지이다.First, the water-based emulsion resin is a water-based polyacrylate emulsion resin containing a hydroxyl group.
이 때, 본 발명에 따른 에너지 절감형 상도용 방수도료 조성물에서 주제부의 수계형 에멀젼 수지는 고형분 함량이 40~60중량%이고, 하이드록실기 함량이 고형분 기준 3~5중량%인 것을 사용하는 것이 바람직하다. 수계형 에멀젼 수지의 고형분 함량이 40중량% 미만인 경우에는 도막의 내화학성이 나빠질 수 있으며, 광택 저하의 문제가 있을 수 있고, 60중량%를 초과하는 경우에는 도료 가격 상승과 은폐력 저하의 문제점이 발생할 수 있다.At this time, in the energy-saving topcoat waterproof paint composition according to the present invention, the water-based emulsion resin of the main part has a solid content of 40 to 60% by weight and a hydroxyl group content of 3 to 5% by weight based on solids. desirable.

본 발명에 따른 에너지 절감형 상도용 방수도료 조성물에서 차열 안료는 0.1~2중량% 포함되는 것이 바람직하며, 0.5~1.5중량% 포함되는 것이 보다 바람직하다. In the waterproof coating composition for energy saving top coating according to the present invention, it is preferable to include 0.1 to 2% by weight of the heat-shielding pigment, and more preferably 0.5 to 1.5% by weight.

본 발명에 따른 에너지 절감형 상도용 방수도료 조성물에서 금속 산화물은 0.5~5중량% 포함되는 것이 바람직하며, 1~3중량% 포함되는 것이 보다 바람직하다.

본 발명에서는 다양한 색상을 구현하기 위하여 금속 산화물이 1,000℃ 전후의 고온에서 소성 반응공정을 통해 Spinel이나 Rutile 등의 매우 안정적인 형태의 분자구조를 갖는 Zn, Pb, Sb, Ti, Cd, Fe, As, Co, Mg, Al, Ni, Mn 등을 고온 소성하여 내후성이 우수하며, 고유의 색상 발현을 하는 차열 유색 무기안료로 사용할 수도 있다.In the present invention, in order to realize various colors, metal oxides have a very stable molecular structure such as Spinel or Rutile through a firing reaction process at a high temperature of around 1,000 ℃, Zn, Pb, Sb, Ti, Cd, Fe, As, It has excellent weatherability by firing Co, Mg, Al, Ni, Mn, etc. at high temperature, and can also be used as a heat-resistant colored inorganic pigment that expresses its own color.
첨가제는 통상에 도장용 도료에 적용되는 방부제, 동결방지제, 분산제, 소포제 증점제, 조막조제 등을 포함할 수 있고, 희석 용제인 물과 함께 5~15중량% 범위 내에서 사용될 수 있다.Additives may include preservatives, antifreezing agents, dispersants, antifoam thickeners, film forming aids, etc., which are usually applied to paints for painting, and may be used in the range of 5 to 15% by weight with water as a diluting solvent.

먼저, 수계형 폴리이소시아네이트는 무황변 타입으로 NCO 비율(%NCO), 즉, 이소시아네이트 함량이 10~20중량% 인 것을 사용하는 것이 바람직하다.First, the water-based polyisocyanate is a non-yellowing type and preferably has an NCO ratio (% NCO), that is, an isocyanate content of 10 to 20% by weight.
경화제부에 적용되는 폴리이소시아네이트는 그 구조 특성상 물과 친하지 않은 소수성 성질을 띠고 있어 수계형 도료에는 수용성(water soluble)으로 개질된 수계형 폴리이소시아네이트를 사용하는 것이 일반적이나, 수계형 폴리이소시아네이트를 단독으로 사용할 경우 주제부와 혼합할 경우 점도 상승의 문제가 발생하기 때문에 수계형 폴리이소시아네이트 55~75중량%를 조용제 20~40중량%와 적절한 비율로 혼합해서 사용하여야 한다.Polyisocyanate applied to the curing agent part has a hydrophobic property that is not friendly to water due to its structure, so it is common to use water-based polyisocyanate modified to be water soluble for water-based paint, but water-based polyisocyanate alone When used, since a problem of viscosity increase occurs when mixed with the main part, 55 to 75% by weight of water-based polyisocyanate should be mixed with 20 to 40% by weight of a co-solvent in an appropriate ratio.
경화제부는 물이 아닌 용제로만 희석이 가능한데 이는 폴리이소시아네이트가 물과 반응하기 때문에 제조 후 2~3일 이내로 굳어지기 때문이다. The curing agent part can be diluted only with a solvent, not water, because polyisocyanate reacts with water and hardens within 2 to 3 days after manufacture.
이 때, 조용제는 프로필렌 글리콜 디아세테이트(CAS: 623-84-7), 디프로필렌 글리콜 n-부틸에테르(CAS: 29911-28-2), 디에틸렌 글리콜 모노부틸에테르(CAS: 112-34-5), 디에틸렌 글리콜 n-부틸 에테르 아세테이트(CAS: 124-17-4) 등을 사용할 수 있으며, 이들을 단독 또는 두 가지 이상을 조합하여 사용할 수도 있다.At this time, the co-solvent is propylene glycol diacetate (CAS: 623-84-7), dipropylene glycol n-butyl ether (CAS: 29911-28-2), diethylene glycol monobutyl ether (CAS: 112-34-5 ), diethylene glycol n-butyl ether acetate (CAS: 124-17-4), and the like, and these may be used alone or in combination of two or more.
본 발명에 따른 에너지 절감형 상도용 방수도료 조성물에서 조용제는 20~40중량% 포함되는 것이 바람직한데, 조용제의 함량이 20중량% 미만인 경우에는 경화제부의 점도가 너무 높아 믹싱이 어렵고, 40중량%를 초과하는 경우에는 도료의 VOC 수치가 높아져 친환경도료로 부적합한 문제점이 있다.In the waterproof paint composition for energy-saving top coating according to the present invention, it is preferable to include 20 to 40% by weight of the co-solvent. If it exceeds, there is a problem that the VOC level of the paint is increased, making it unsuitable as an eco-friendly paint.
