Abstract
Description
본 발명은 콘크리트 구조물에 있어서 유해물질의 침투로부터 보호하여 장기 내구성을 증진시키고 강재의 부식을 방지하며 콘트리트 표면 또는 강재의 표면에 도장을 위해 사용되는 도료 조성물에 관한 것으로, 보다 상세하게는 콘크리트의 내구성 증진을 위한 도장 및 강재의 방청 등을 위해 수산화알카리금속, 고로슬래그와 에폭시수지 및 연성수지를 주성분으로 사용하여 이를 일정비로 혼합함으로서 콘크리트와의 장기 부착성능을 향상시키고 방청성 및 내구성을 보강할 수 있을 뿐만 아니라 피도체의 수분면 및 유분면 모두에 대해 도색이 가능한 콘크리트 내구성 증진 및 강재 방청용 도료 조성물에 관한 것이다.The present invention relates to a paint composition used to protect long-term durability by preventing the penetration of harmful substances in concrete structures, to prevent corrosion of steel, and to paint on the surface of concrete or steel, and more particularly, durability of concrete. Alkali metal hydroxide, blast furnace slag, epoxy resin and soft resin are used as the main ingredients for painting and rust prevention of steel materials, and they are mixed at a constant ratio to improve long-term adhesion performance with concrete and reinforce rust resistance and durability. In addition, the present invention relates to concrete durability enhancement and steel rust preventive coating compositions that can be painted on both the water and oil side of the subject.
콘크리트 구조물이 열악한 환경에 축조되는 경우, 유해이온의 침투로 인하여 강도가 저하될 뿐만 아니라 콘크리트 속의 철근이 부식되어 내구성이 현저히 떨어져 사용수명이 감소되는 실정이다. 특히 바닷가에 축조되어 염분의 침투를 받거나 하수나 공장폐수지역에 축조되어 여러 화학약품에 및 도심지나 공장지역에서 탄산가스에 노출되는 경우에는 심각한 내구성 저하가 일어난다.When the concrete structure is constructed in a poor environment, not only the strength decreases due to the penetration of harmful ions, but also the durability of the steel is significantly reduced due to corrosion of the reinforcing steel in the concrete, which reduces the service life. In particular, severe degradation of durability occurs when exposed to various chemicals and carbon dioxide gas in urban areas or factory areas by being built in the sea and receiving salt infiltration or in sewage or factory wastewater areas.
따라서 이러한 콘크리트의 내구성 저하를 억제하기 위하여 콘크리트나 강재의 표면에 도장을 하여 유해이온을 차단하고 있으나, 종래의 도료 조성물은 콘크리트의 특성을 고려하지 않은 성분으로 구성되어 있어 콘크리트 표면에 시공시 작업성과 콘크리트와의 장기 접착성능이 떨어져 도장막이 오래가지 못하고 떨어진다는 문제점이 있었다.Therefore, in order to suppress the deterioration of the durability of concrete, the surface of concrete or steel is coated to block harmful ions, but the conventional coating composition is composed of components that do not consider the characteristics of concrete. There is a problem that the coating film does not last long, because the long-term adhesion performance with the concrete falls.
종래에는 도료 조성물의 충진제로서 주로 탄산칼슘(CaCO3), 유리섬유(Glass Fiber), 운모(Mica) 등과 흡습성을 낮추기 위해 실리카 등이 이용되어 왔으나, 이러한 물질들은 주로 물리적 성질의 개선과 단순히 충진제로서의 역할로 도료조성물의 가격을 낮추기 위해 사용되었을 뿐, 도료의 접착성이나 내구성, 내마모성의 개선에는 역할을 하지 못하였다.Conventionally, silica has been used as a filler for coating compositions to reduce hygroscopicity such as calcium carbonate (CaCO 3 ), glass fiber, glass mica, mica, etc., but these materials are mainly used for improving physical properties and simply as fillers. It was used to lower the cost of paint compositions, but did not play a role in improving the adhesion, durability, and abrasion resistance of paints.
한편, 고로슬래그(Blast Furnace Slag)는 충진제(Filler)로 사용하는 것으로, 충진제는 합성 화합물인 도료 제조시 물리적인 성질을 변화시키거나 제조단가를 내리는 것을 목적으로 첨가하는 물질로, 종래에는 주로 탄산칼슘(CaCO3), 유리섬유(Glass Fiber), 운모(Mica) 그리고 흡습성을 낮추기 위하여 실리카 등이 주로 이용되어 왔다.On the other hand, blast furnace slag (Blast Furnace Slag) is used as a filler (Filler), the filler is a material that is added for the purpose of changing the physical properties or manufacturing costs in the manufacture of a synthetic compound paint, conventionally mainly carbonic acid Calcium (CaCO 3 ), glass fiber (Glass Fiber), mica (Mica) and silica to reduce the hygroscopicity has been mainly used.
그러나 이러한 물질들은 열에 의한 변형이 많고 내구성, 내식성, 내마모성 등의 특징은 나타내지 못하는 소재들이 대부분이기 때문에 단순히 중량재 역할을 주로 해왔다.However, these materials have been mainly serving as heavy materials because they are mostly materials that are highly deformed by heat and do not exhibit characteristics such as durability, corrosion resistance and abrasion resistance.
이와 같이 산업폐기물로 많은 양이 산출되는 고로슬래그는 산업폐기물이지만 시멘트산업에서 중요한 재료인데, 특히 레미콘을 제조하는데 있어 시멘트와 상당량을 혼합하여 우수한 강도의 콘크리트를 생산할 수 있는바, 시멘트의 절약에도 중요한 역할을 한다. 결국 고로슬래그는 철과 시멘트와의 친화성이 대단히 높다는 것을 알 수 있다.As such, blast furnace slag, which produces a large amount of industrial waste, is industrial waste, but is an important material in the cement industry.In particular, in manufacturing ready concrete, it is possible to produce concrete of high strength by mixing cement and a considerable amount. Play a role. As a result, the blast furnace slag has a very high affinity between iron and cement.
연성수지는 에폭시수지의 시멘트 및 철과의 높은 친화력에도 불구하고 낮은 유연성으로 인한 피도체면과 분리현상을 막기 위하여 첨가하는 물질로서, 아크릴, 우레탄수지, 스티렌부탄디엔고무(SBR : Styrene Butadiene Rubber), 엔비아르(NBR : Nitrile Butadiene Rubber) 등을 사용할 수 있다. 특히 에폭시수지는 낮은 유연성으로 인하여 내진동성이 크게 떨어지는 단점이 있다.Flexible resin is added to prevent the surface of the surface and separation due to low flexibility despite the high affinity with cement and iron of epoxy resin.Acrylic, urethane resin, styrene-butanediene rubber (SBR) , Nitrile Butadiene Rubber (NBR) and the like can be used. In particular, epoxy resins have a disadvantage in that vibration resistance is greatly reduced due to low flexibility.
종래에는 에폭시수지의 경우 경화제로서 폴리아마이드 아민류 물질을 사용함으로서 경화시켰으나, 이 경우 빠른 경화속도로 인해 응력이 발생하여 피도체와의 밀착성이 떨어지고 내구성도 떨어지는 현상이 발생하여 왔다.Conventionally, in the case of epoxy resin, it was cured by using a polyamide amine material as a curing agent, but in this case, a stress is generated due to a fast curing rate, resulting in poor adhesion to the subject and poor durability.
즉, 종래에 주로 사용되는 에폭시수지 등은 초기 접척성능은 우수하지만 낮은 유연성으로 인해 장기적으로 콘크리트나 강재 등의 피도체면과의 접착성능이 떨어진다는 문제점이 있는데, 특히 에폭시수지의 경화제로서 아민류 물질을 사용할 경우 빠른 경화속도로 인하여 내부응력이 발생하여 피도체와의 밀착성이 떨어지고 내구성이 떨어지는 현상이 발생하였다.That is, epoxy resins, which are commonly used in the related art, have excellent initial contact performance, but have a problem in that adhesion performance with a surface of a material such as concrete or steel is inferior in the long term due to low flexibility. In particular, amines are used as a curing agent for epoxy resins. In the case of using, the internal stress occurred due to the fast curing speed, resulting in poor adhesion to the subject and poor durability.
본 발명은 종래에 콘크리트 방청용으로 주로 사용되는 에폭시수지 등이 초기 접착성능은 우수하지만 낮은 유연성으로 인해 장기적으로 콘크리트나 강재 등의 피도체면과의 접착성능이 떨어지는 문제점을 극복하고자 개발된 것으로, 수산화알카리금속을 함유하여 산성분 중화에 탁월한 효과가 있어 철판 등의 강재에 사용시 방청효과가 뛰어나고 콘크리트와의 부착력도 우수한 고로슬래그를 기본적으로 적용시킴으로서, 부착강도가 우수하고 방청효과가 뛰어난 콘크리트 내구성 증진 및 강재 방청용 도료 조성물을 제공함에 목적이 있다.The present invention was developed to overcome the problem that the conventional epoxy resin mainly used for rust prevention of concrete is excellent in the initial adhesive performance but low adhesion performance with the surface of the conductor such as concrete or steel due to low flexibility, Containing alkali metal hydroxide, it has an excellent effect on neutralizing acid component. By applying blast furnace slag with excellent anti-rusting effect and excellent adhesion with concrete when used in steel such as steel plate, it improves concrete durability with excellent adhesion strength and excellent anti-rusting effect. And to provide a steel anti-corrosive coating composition.
특히 연성수지를 첨가하여 유연성을 높여 피도체면과의 분리를 막아 내진동성을 높게 하며, 수산화알카리금속을 에폭시수지의 경화제로 사용하여 경화속도를 늦춤으로서 낮은 응력으로 피도체면과의 밀착성을 높일 수 있을 뿐만 아니라, 장기적으로 피도체면과의 분리가 일어나지 않는 콘크리트 내구성 증진 및 강재 방청용 도료 조성물을 제공함에도 보다 근본적인 목적이 있다.Particularly, flexible resin is added to increase the flexibility to prevent separation from the surface of the object, to increase vibration resistance, and to improve adhesion to the surface of the object with low stress by slowing down the curing speed by using alkali metal hydroxide as a curing agent of epoxy resin. Not only that, but also to provide a coating composition for improving concrete durability and steel rust preventive does not occur in the long-term separation with the surface of the object is a more fundamental purpose.
이와 같은 목적을 달성하기 위해 본 발명의 콘크리트 내구성 증진 및 강재 방청용 도료 조성물은 기본적으로, 충진제로서 10-40중량%의 고로슬래그, 25-60중량%의 연성수지, 에폭시 경화제로서 1-20중량%의 수산화알카리금속, 0.1-15중량%의 에폭시수지를 포함하여 구성된다.In order to achieve the above object, the coating composition for concrete durability improvement and steel rust prevention of the present invention is basically 10 to 40% by weight of blast furnace slag, 25 to 60% by weight of soft resin, and 1 to 20 weight of epoxy curing agent. % Alkali metal hydroxide, 0.1-15% by weight of epoxy resin.
특히 고로슬래그는 CaO 30-50중량%, SiO2 30-50중량%, Al2O3 10-30중량%, MgO 1-10중량%, Fe2O3 3중량% 이하로 조성되며, 이러한 상기 고로슬래그의 각 성분을 별 도로 혼합하여 전체의 조성물에 첨가할 수 있다.In particular, the blast furnace slag is composed of 30-50% by weight of CaO, 30-50% by weight of SiO 2 , 10-30% by weight of Al 2 O 3 , 1-10% by weight of MgO, 3% by weight of Fe 2 O 3 , Each component of the blast furnace slag can be mixed separately and added to the whole composition.
또한 연성수지는 아크릴수지, 메타아크릴수지, 우레탄수지, 페녹시수지, 스티렌수지, 천연고무, SBR, NBR중 어느 하나 또는 이들의 공중합체를 선택적으로 사용한다.In addition, the flexible resin is optionally used any one or copolymers of acrylic resin, methacrylic resin, urethane resin, phenoxy resin, styrene resin, natural rubber, SBR, NBR.
그리고 수산화알카리금속은 NaOH, KOH, Ca(OH)2, Mg(OH)2 중 하나 또는 이들의 혼합물을 첨가하게 되며, 에폭시수지는 비스페놀 A, 비스페놀 F계의 에폭시수지 또는 이들의 공중합체 또는 혼합물을 첨가하는 것을 기술적 특징으로 한다.And the alkali metal hydroxide is added to NaOH, KOH, Ca (OH) 2 , Mg (OH) 2 or a mixture thereof, epoxy resin bisphenol A, bisphenol F-based epoxy resin or a copolymer or mixture thereof It is a technical feature to add.
우선 본 발명의 도료 조성물은 기존에 경화 에폭시수지 도료의 단점인 높은 응력, 고흡습성 및 낮은 유연성으로 인하여 시간이 경과함에 따라 피도체면(주로 콘크리트, 강재)과의 밀착성이 저하되고, 또한 침투하는 산성분을 중화시키는 내부성분 부족으로 도료 자체는 물론 피도체의 장기 내구성을 보장받지 못했을 뿐만 아니라, 특히 0.8% 이상의 수분을 함유했을 시에나 결로 생성시에 작업진행이 어려웠던 점을 해결하기 위한 방안으로 개발된 것이다.First of all, the coating composition of the present invention has a high stress, high hygroscopicity, and low flexibility, which are disadvantages of the cured epoxy resin coating, and thus, the adhesion to the surface of the substrate (mainly concrete, steel) decreases, and also penetrates. The lack of internal components that neutralize the acid component did not guarantee the long-term durability of the coating itself or the subjects, and was developed as a solution to solve the difficulties in the work progress, especially when it contained more than 0.8% water or when condensation was generated. It is.
일반적으로 종래의 에폭시수지 경화제로 폴리아마이드 또는 아민류를 사용하지 않고 수산화알카리금속류가 상온에서 경화시키는 것을 이용하여 낮은 흡습성을 지닌 제품을 얻을 수 있었고, 특히 수분면의 도색도 가능한 도료를 얻을 수 있었음에 착안하였다.In general, a product having low hygroscopicity can be obtained by curing alkali metal hydroxides at room temperature without using polyamide or amines as a conventional epoxy resin curing agent. I thought about it.
즉, 보통 낮은 흡습성을 지닌 도료를 얻기 위해서는 고충진 타입의 충진제인 실리카 파우더를 사용하나, 이것은 외부에서 침투되는 산성분을 중화시키는 역할은 못하고 시간이 경과할수록 수분과의 결합으로 인한 너무 강한 도막의 형성과 피도체와의 친화성 부족으로 균열 및 박리현상을 가져올 수 있으므로, 같은 고충진제에 속하고 수산화알카리금속과 함께 산성분을 중화시키는데 탁월한 효과가 있는 염기성 산화물이 다량 함유되어 있으며, 피도체와 친화성 콘크리트면의 유리 수산화칼슘과 화학적으로 반응하여 부착강도와 내구성이 우수한 고로슬래그를 기본 성분으로 이용하여 본 발명의 도료 조성물을 생산하게 된 것이다.In other words, to obtain a paint with low hygroscopicity, silica powder, which is a high-filling type filler, is used, but this does not neutralize the acid component that penetrates from the outside. Since cracking and peeling may occur due to formation and lack of affinity with the subject, it contains a large amount of basic oxide, which belongs to the same high filler and has an excellent effect on neutralizing acid components together with alkali metal hydroxide. By chemically reacting with free calcium hydroxide on the affinity concrete surface, the coating composition of the present invention is produced using blast furnace slag having excellent adhesion strength and durability as a basic component.
특히 본 발명의 도료 조성물은 에폭시도료의 최대 단점인 유연성 부족 때문에 아크릴우레탄수지를 첨가하여 생산할 결과, 어떤 진동에서도 견딜 수 있는 특징을 볼 수 있다.In particular, the coating composition of the present invention can be produced by adding an acrylic urethane resin due to the lack of flexibility, which is the biggest disadvantage of the epoxy paint, it can be seen a feature that can withstand any vibration.
결국 본 발명은 콘크리트 구조물에 있어서 유해물질의 침투로부터 보호하여 장기 내구성을 증진시키고, 강재의 부식을 방지하기 위하여 콘크리트 표면 또는 강재의 표면에 도장을 위해 사용하는 도료 조성물을 제공하고자 하는바, 기본적으로 고로슬래그와 연성수지를 주성분으로 하고, 에폭시수지의 상온경화제로 수산화알카리금속을 사용함을 특징으로 한다.After all, the present invention is to provide a coating composition to be used for painting on the concrete surface or the surface of the steel in order to improve the long-term durability by protecting against the penetration of harmful substances in the concrete structure, and to prevent corrosion of the steel, basically Blast furnace slag and soft resin are main components, and alkali metal hydroxide is used as room temperature curing agent of epoxy resin.
특히 고로슬래그는 그 성분이 시멘트성분과 유사하여 시멘트 제조시 많이 사용되고 있는 제철산업의 산업부산물로, 본 발명에서는 이러한 점을 이용하여 도료 조성물의 충진제(Filler)로서 상기 고로슬래그를 주성분으로 사용함으로서 접착성 및 내구성, 내마모성을 증진시킬 수 있다.In particular, the blast furnace slag is an industrial by-product of the steel industry which is used a lot in the manufacture of cement because its composition is similar to the cement component, and in the present invention, the blast furnace slag is used as a filler in the coating composition to bond the blast furnace slag as a main component. It can improve the durability, wear resistance.
즉, 본 발명의 도료 조성물은 기본적으로 에폭시수지의 우수한 초기 접착성능의 장점을 이용하면서 지금까지의 도료 조성물이 해결하지 못했던 단점을 보완하고 자 에폭시수지의 경화제로서 수산화알카리금속을 사용하는 것이다.In other words, the coating composition of the present invention basically uses the advantages of the excellent initial adhesive performance of the epoxy resin, while using the alkali metal hydroxide as a curing agent of the epoxy resin to compensate for the disadvantages that the paint composition has not solved so far.
우선 본 발명에 사용되는 고로슬래그는 다음과 같은 성분으로 조성된다.First, the blast furnace slag used in the present invention is composed of the following components.
먼저 수산화알카리금속인 Ca(OH)2는 에폭시수지의 경화제 역할을 하는데, 특히 콘크리트면이나 강판 공극에 잔류하는 수분과 반응하여 도료와 피도체간의 접착율을 완벽하게 해주고, 반응 후에 수축 또는 변형이 발생되지 않도록 하는 역할을 하게 된다.First, Ca (OH) 2 , an alkali metal hydroxide, acts as a curing agent for epoxy resins. In particular, it reacts with moisture remaining in the concrete surface or steel plate voids to perfect adhesion between the paint and the workpiece. It is to prevent the occurrence.
그리고 염기성 산화물인 CaO가 30-50중량%이 포함되는데, 이는 외부 침입의 산성분을 중화시키고 피도체와의 강한 밀착성을 증진시킴으로서 내마모 및 내구성, 내식성을 향상시킬 수 있고, 알카리성을 부여하게 된다. The basic oxide CaO is 30-50% by weight, which neutralizes acid components of external invasion and enhances strong adhesion with the conductor, thereby improving wear resistance, durability and corrosion resistance, and giving alkalinity. .
그리고 SiO2는 30-50중량% 포함되어 활성 실리카가 콘크리트 표면의 수산화칼슘과 반응하여 규산칼슘을 생성함으로서, 도료 조직의 치밀성을 향상시켜 결국 콘크리트 및 강재에 대한 부착강도를 향상시키게 된다.In addition, SiO 2 is contained 30-50% by weight, the active silica reacts with calcium hydroxide on the surface of the concrete to produce calcium silicate, thereby improving the compactness of the paint structure to improve the adhesion strength to the concrete and steel.
그리고 Al2O3는 10-30중량%로 포함되는데, 이는 내열성 및 내구성, 내화학성의 향상과 함께 알카리성을 부여하게 된다.And Al 2 O 3 is included in 10-30% by weight, which gives the alkalinity with improved heat resistance and durability, chemical resistance.
또한 알카리금속산화물인 MgO이 상대적으로 소량인 1-10중량% 정도로 포함되는데, 염기성 산화물로서 외부침입의 산성분을 중화시키는 역할을 하게 된다. 그 외 기타 불순물을 포함한 3중량% 이하의 Fe2O3이 포함되어 알카리성을 부여하게 된다.In addition, MgO, which is an alkali metal oxide, is included in a relatively small amount of 1-10% by weight, and serves as a basic oxide to neutralize acid components of external intrusion. Other than 3% by weight of Fe 2 O 3 including other impurities are included to impart alkalinity.
그밖에 필요에 따라 첨가될 수 있는 아크릴우레탄수지의 경우 강한 도막의 형 성 성분들을 유연성이 높은 도막으로 형성함과 동시에 피도체와의 접착성을 높이게 한다.In addition, in the case of acrylic urethane resin that can be added as needed, forming a strong coating film forming components to a highly flexible coating and at the same time to improve the adhesion to the object.
즉, 이와 같은 성분들이 일정비로 첨가되어 혼합되는 본 발명의 도료 조성물은 도료의 화학수지 고흡습성을 고로슬래그가 수분 및 산성분과 화학반응하여 기본적으로 습윤면의 접착은 물론, 중성화 방지 및 방청성을 높일 수 있다.That is, the coating composition of the present invention in which such components are added and mixed at a constant ratio has a high chemical hygroscopic property of the paint, so that the blast furnace slag chemically reacts with the moisture and acid components to improve adhesion to the wet surface, as well as to prevent neutralization and rust resistance. Can be.
특히 염기성 산화물인 CaO와 MgO는 피도체에 알카리성 보호막과 그 환경성을 조성하여 피도체의 수명을 연장시키게 된다.In particular, basic oxides CaO and MgO extend the life of the object by forming an alkaline protective film and its environmental properties.
결국 고로슬래그를 에폭시수지, 연성수지 도료의 충진제로 사용함으로서, 기존의 일반 도료보다 밀착성이 훨씬 뛰어날 뿐만 아니라 에폭시수지의 단점을 보완해주는 효과가 뛰어난 것을 알 수 있다.After all, by using the blast furnace slag as a filler for epoxy resin and soft resin paint, it can be seen that not only the adhesion is much better than conventional paint but also the effect of compensating for the disadvantages of epoxy resin is excellent.
본 발명의 조성물은 위와 같은 기능을 하는 분말상태의 고로슬래그와 연성수지, 경화되지 않은 액상의 에폭시수지, 에폭시수지의 경화를 위한 수산화알카리금속으로 구성되며, 본 발명의 부착성 및 내구성이 우수한 도료 조성물에 대한 구체적인 조성범위는 이하의 바람직한 실시예를 통해 상세히 설명한다.The composition of the present invention is composed of a powdered blast furnace slag and a soft resin, an uncured liquid epoxy resin, alkali metal hydroxide for curing the epoxy resin, and excellent adhesion and durability of the present invention Specific composition ranges for the composition will be described in detail through the following preferred examples.
