Description

고탄력 및 내산성 페인트 조성 및 이의 제조 방법{HIGH RESILIENT AND ACID RESISTANT COATING MATERIALS AND MANUFACTURING METHOD FOR THE SAME}High-elasticity and acid-resistant paint composition and its manufacturing method {HIGH RESILIENT AND ACID RESISTANT COATING MATERIALS AND MANUFACTURING METHOD FOR THE SAME}

본 발명은 고탄력 내산성 페인트 조성 및 이의 제조 방법에 대한 것으로서, 보다 구체적으로는, 내산성과 고탄성이 동시에 요구되는 공장 바닥용 및 기타 산업에 사용되는 페인트 조성물 및 이의 제조 방법에 대한 것이다. The present invention relates to a high-elastic acid-resistant paint composition and a method for producing the same, and more specifically, to a paint composition used in factory floors and other industries that require both acid resistance and high elasticity, and a method of manufacturing the same.

일반적으로, 토목, 건축 분야에서는 건축물의 노화 방지 및 누수 억제를 위해 건축물의 옥상, 지하층 및 외벽, 더 나아가 공장 바닥 등에 필수적으로 방수 작업을 수행하고 있다. 시멘트 등의 충전재에 에폭시수지나 우레탄수지와 같은 화학혼화제를 혼합한 몰탈 조성물들이 건축물의 방수처리, 내벽 및 외벽 등 표면화장, 보수재, 마감재, 포장재 등에 사용되고있다.In general, in the fields of civil engineering and construction, waterproofing work is essentially performed on the roof of the building, the basement floor and the outer wall, and furthermore, the factory floor, etc. to prevent aging and water leakage of the building. Mortar compositions in which chemical admixtures such as epoxy resin or urethane resin are mixed with fillers such as cement are used for waterproofing of buildings, surface makeup such as inner and outer walls, repair materials, finishing materials, and packaging materials.

에폭시수지계의 경우, 탄성이 극히 적어서 충격에 의해 깨지기쉽고 하지층 콘크리트와의 열팽창계수 차이로 인해 냉,고온 접촉시 들뜸현상이 발생하는 문제가 있다. 또한, 에폭시수지는 폴리아민 등과 같은 방향성이 강한 경화제와 독성이 강한 점도조절제를 사용하기 때문에 냄새가 강하고 환경유해물질을 발생시킨다.In the case of the epoxy resin system, the elasticity is extremely low, so it is easy to break due to impact, and there is a problem that a lifting phenomenon occurs during cold and high temperature contact due to the difference in thermal expansion coefficient with the underlying concrete. In addition, the epoxy resin has a strong odor and generates environmentally harmful substances because a curing agent with strong orientation such as polyamine and a viscosity modifier with strong toxicity are used.

반면 우레탄수지계 몰탈은 신장률, 인장률이 크므로 균열 추종성이 좋고 내구성이 뛰어나다는 장점이 있다. 그러나, 우레탄 방수공법은 경화제 안에 함유된 이소시아네이트(NCO)라는 물질이 물과 접촉하여 반응하게 되면, 이산화탄소가 발생하여 방수층이 부풀어 오르고 핀홀 및 들뜸 현상이 일어나게 되는 문제가 있다. 종래의 우레탄 바닥마감공법 및 2액형 유성제품은 함수율 8% 이하일 경우(육안의 확인시 바닥면이 건조된 상태뿐만 아니라, 모체안에 습기가 함습되어 있지 않은 상태)에만 가능하다. 하지만, 4계절이 뚜렷한 우리나라의 경우 날씨의 변동이 심하여 옥외의 바탕면에는 함수율을 8% 이하로 맞추어 시공하기가 매우 어렵다. 특히, 습윤 바탕면에는 우레탄 방수시공 전 반드시 접착력의 보장을 위하여 프라이머 공정이 수행되어야 하는 번거로움이 있었다.On the other hand, urethane resin mortar has the advantage of good crack followability and excellent durability because of its high elongation and elongation. However, in the urethane waterproofing method, when a material called isocyanate (NCO) contained in the curing agent comes into contact with water and reacts, carbon dioxide is generated, the waterproof layer swells, and pinholes and lifting phenomena occur. The conventional urethane floor finishing method and two-component oily products are only possible when the moisture content is less than 8% (not only when the bottom surface is dry when visually checked, but also when there is no moisture in the parent body). However, in Korea, where the four seasons are distinct, the weather fluctuates severely, so it is very difficult to construct an outdoor base with a moisture content of 8% or less. In particular, there was an inconvenience that a primer process must be performed to ensure adhesion before urethane waterproofing on the wet base surface.

이상 살펴본 바와 같이, 우레탄계, 에폭시계 방수재는 이음매 없는(seamless) 방수층을 형성하기 때문에 복잡한 부분이나 수직부분의 시공이 용이하지만, 하지와의 부착력이 부족하고 기포발생에 의해서 국부적인 부박현상과 같은 하자 발생이 자주 일어난다. 특히 하지의 수분함량을 8% 이하인 조건에서 시공하여야 하는 것을 원칙으로 하고 있어서 한계가 있다.As discussed above, since urethane-based and epoxy-based waterproofing materials form a seamless waterproof layer, it is easy to construct complex or vertical parts, but defects such as local swelling phenomenon due to insufficient adhesion to the base and generation of air bubbles. Occurrence occurs frequently. In particular, there is a limit as it is a principle that it must be constructed under the condition that the moisture content of the base is less than 8%.

또한, 기존의 도막 방수재는 각종 희석재와 미반응 단량체들과 같은 휘발성 유기화합물을 다량 사용하므로 식품 공장, 전자기기공장, 반도체 공장, 정밀화학공장 등과 같이 고도의 청결성이 요구되는 곳에는 사용할 수가 없다. 위와 같은 현재 사용되고 있는 여러 시멘트 조성물들은 특성 면에서 뿐 아니라 환경적인 면에서도 여러가지 문제점을 내포하고 있어, 친환경적인 시멘트 조성물 개발의 필요성이 대두된다. In addition, since the existing waterproofing material uses a large amount of volatile organic compounds such as various diluents and unreacted monomers, it cannot be used in places requiring high level of cleanliness such as food factories, electronics factories, semiconductor factories, and fine chemical factories. . The various cement compositions that are currently used as described above have various problems not only in terms of characteristics but also in terms of the environment, and thus the need to develop eco-friendly cement compositions has emerged.
