Description
본 발명은 환경 친화성 콘크리트 침투 방지의 상도 도장을 위한 세라믹 도료 조성물 및 그 제조방법에 관한 것이고, 구체적으로 콜로이드 실리카를 포함하는 무기 바인더에 소수성 관능기를 부가하여 제조되는 콘크리트 침투 방지의 상도 도장을 위한 세라믹 도료 조성물 및 그 제조방법에 관한 것이다. The present invention relates to a ceramic coating composition for top coat of environmentally friendly concrete penetration prevention, and a method for manufacturing the same, and specifically, for top coat coating of concrete penetration prevention prepared by adding a hydrophobic functional group to an inorganic binder including colloidal silica. A ceramic coating composition and its manufacturing method.
바인더(binder), 경화제(Curing agent), 첨가제 및 안료를 포함하는 도료는 바인더 또는 경화제의 성분에 따라 유기 도료와 무기 도료로 나누어질 수 있다. 유기 도료는 아크릴 수지, 에폭시 수지 또는 에스테르 수지가 바인더 또는 경화제로 사용되고 무기 도료의 경우 실리카 또는 실리케이트가 바인더로 사용되고 소량의 수지가 경화제로 사용될 수 있다. 바인더와 경화제가 별도로 제조되어 도장 과정에서 혼합되는 2액형 유기도료는 휘발성 유기 화합물을 발생을 발생시킬 수 있어 이에 대한 대안으로 수계도료 또는 분체도료가 개발되었다. 그러나 수계도료 또는 분체도료는 여전히 유기 성분의 수지를 포함하는 한편 도막 물성이 떨어지고 도장 작 업이 복잡하다는 문제점을 가진다. Paints including binders, curing agents, additives and pigments may be divided into organic paints and inorganic paints depending on the components of the binder or hardener. In organic paints, acrylic resins, epoxy resins or ester resins may be used as binders or curing agents, in the case of inorganic paints, silica or silicates may be used as binders, and small amounts of resins may be used as curing agents. The two-component organic paint, which is prepared separately from the binder and the curing agent and mixed in the coating process, may generate volatile organic compounds, so that an aqueous or powder coating has been developed as an alternative thereto. However, the water-based coating or powder coating still contains a resin of an organic component, while having a problem of poor coating properties and complicated painting operations.

Inorganic paints are advantageous from an environmental point of view as compared to organic paints, but they have disadvantages in that they are difficult to cure due to weak coating properties and adhesion. In contrast, water-based paints or powder paints, which are alternative paints to organic solvent-type paints, have a disadvantage in that the manufacturing process is complicated and coating properties are poor and product uniformity is difficult.

Hereinafter, the present invention will be described in detail with reference to the embodiments set forth in the accompanying drawings, but the embodiments are illustrative for clarity of understanding and the scope of the present invention is not limited thereto.
도 1은 친환경성 콘크리트 침투 방지의 상도 도장을 위한 세라믹 도료 조성물의 제조 공정을 개략적으로 도시한 것이다. Figure 1 schematically shows a manufacturing process of the ceramic coating composition for the top coating of environmentally friendly concrete penetration prevention.
도 1을 참조하면, 세라믹 도료 조성물의 제조 공정은 제1 반응 용액을 제조하는 공정(P11); 부가 반응의 유도를 위한 제2 반응 용액을 제조하는 단계(P12); 제1 반응 용액과 제2 반응 용액을 투입하여 바인더를 제조하는 단계(P13); 및 충진재를 첨가하는 단계(P14)를 포함한다. Referring to FIG. 1, the manufacturing process of the ceramic coating composition may include preparing a first reaction solution (P11); Preparing a second reaction solution for inducing addition reaction (P12); Preparing a binder by adding a first reaction solution and a second reaction solution (P13); And adding the filler (P14).
상도 코팅 바인더의 제조를 위하여 먼저 증류수와 실리카 졸이 준비되고 실리카 졸이 증류수에 투입되어야 한다(P11). 증류수는 이온 교환수와 같이 알칼리 또는 산성 이온 성분을 포함하지 않은 물을 의미하고 pH는 7에 근사한 값을 가질 수 있다. 실리카 졸(Silica-sol)은 실리카 또는 이산화규소(SiO2)가 콜로이드 상태로 존재하는 콜로이드 실리카를 말한다. 콜로이드 실리카는 액체상(liquid phase)으로 존재하는 무정형의 구형 실리카로 알칼리 실리케이트(alkali silicate)로부터 만들어질 수 있다. 콜로이드 실리카는 1~5 ㎚의 크기를 가지는 실리카 핵으로부터 만들어지고 예를 들어 아래와 같이 실란으로부터 만들어질 수 있다. To prepare a top coat binder, distilled water and silica sol must first be prepared and silica sol must be added to distilled water (P11). Distilled water means water that does not contain alkali or acidic ionic components, such as ion-exchanged water, and pH may have a value close to 7. Silica sol refers to colloidal silica in which silica or silicon dioxide (SiO 2 ) is present in a colloidal state. Colloidal silica can be made from alkali silicates with amorphous spherical silica present in the liquid phase. Colloidal silica is made from silica nuclei having a size of 1-5 nm and can be made from silanes, for example, as follows.
SiH4 + 2O2 → SiO2 + 2 H2O SiH 4 + 2O 2 → SiO 2 + 2 H 2 O
실리카 핵은 pH가 7보다 큰 용액에서 서로 분리되어 점차로 성장하여 실리카 졸(silica sol) 또는 콜로이드 서스펜션(colloid suspension)을 형성하게 되고 전기적으로 음성을 띠게 된다. 실리카 졸 또는 콜로이드 실리카는 pH 조절제에 의하 여 안정된 상태를 유지하고 콜로이드 실리카의 고형분 양은 실리카 입자의 크기에 의하여 결정될 수 있다. 예를 들어 실리카 입자의 평균 직경이 50 ㎚가 된다면 고형분은 50 wt%가 될 수 있는 반면 실리카 입자의 평균 직경이 10 ㎚라면 단지 고형분은 30 wt%까지만 만들어질 수 있다. Silica nuclei are separated from each other in a solution with a pH greater than 7 and gradually grow to form a silica sol or a colloidal suspension and become electrically negative. The silica sol or colloidal silica remains stable by the pH adjuster and the solids content of the colloidal silica can be determined by the size of the silica particles. For example, if the average diameter of the silica particles is 50 nm, the solids can be 50 wt%, while if the average diameter of the silica particles is 10 nm, only solids can be made up to 30 wt%.
본 발명에 따른 바인더 제조를 위한 실리카 졸의 평균 직경은 10 내지 200 ㎚가 될 수 있고 고형분은 30 내지 50 wt%, 바람직하게 30 내지 40 wt%가 될 수 있다. 제1 상도 용액의 제조를 위하여 증류수와 실리카 졸에 추가로 초산이 첨가될 수 있다. 중량비율로 증류수: 실리카 졸: 초산 = 1: 0.6~1.0: 0.006~0.01이 될 수 있다. 상도 코팅 바인더 전체에 대한 중량 비율은 증류수 12~18 wt%, 실리카 졸 9~15 wt% 그리고 초산 0.0008~0.0018 wt%가 될 수 있다. The average diameter of the silica sol for the preparation of the binder according to the invention can be from 10 to 200 nm and the solid content can be from 30 to 50 wt%, preferably from 30 to 40 wt%. Acetic acid may be additionally added to the distilled water and the silica sol to prepare the first top solution. The weight ratio may be distilled water: silica sol: acetic acid = 1: 0.6 to 1.0: 0.006 to 0.01. The weight ratio of the top coat binder as a whole may be 12 to 18 wt% of distilled water, 9 to 15 wt% of silica sol, and 0.0008 to 0.0018 wt% of acetic acid.
증류수와 실리카 졸의 혼합을 위하여 먼저 증류수가 반응용기에 투입되어 20 내지 30℃의 온도로 유지되고 초산이 교반과 함께 투입될 수 있다. 이후 실리카 졸이 반응 용기에 투입되고 반응용기의 온도를 25 내지 45 ℃로 유지하면서 교반을 하여 제1 상도 용액을 제조한다(P11). 위에서 반응용기에 차례대로 증류수, 초산 및 실리카 졸이 투입되는 것으로 제시되어 있지만 투입순서에 의하여 본 발명은 제한되지 않는다. 증류수, 실리카 졸 및 초산을 포함하는 제1 반응 용액은 콜로이드 서스펜션의 상태가 되고 용액 전체에 걸쳐 실리카 입자가 균일하게 분산된 형태가 된다.In order to mix the distilled water and the silica sol, distilled water is first added to the reaction vessel and maintained at a temperature of 20 to 30 ° C., and acetic acid may be added with stirring. After that, the silica sol is added to the reaction vessel and stirred while maintaining the temperature of the reaction vessel at 25 to 45 ° C. to prepare a first top solution (P11). Distilled water, acetic acid and silica sol are sequentially introduced into the reaction vessel in the above, but the present invention is not limited by the order of addition. The first reaction solution containing distilled water, silica sol and acetic acid is in the form of a colloidal suspension, and the silica particles are uniformly dispersed throughout the solution.
제2 반응 용액의 제조를 위하여 메탄올 및 메틸트리메톡시실란(MTS)이 준비된다. 중량비로 메틸트리메톡시실란: 메탄올 = 1: 0.5~0.7, 그리고 상도 코팅 바인 더 전체 중량에 대하여 메틸트리메톡시실란 40~53 wt% 그리고 메탄올 25~32 wt%가 준비되고 혼합 용기에 투입되어 교반될 수 있다.Methanol and methyltrimethoxysilane (MTS) are prepared for the preparation of the second reaction solution. Methyltrimethoxysilane by weight ratio: methanol = 1: 0.5 to 0.7, and 40 to 53 wt% of methyltrimethoxysilane and 25 to 32 wt% of methanol were prepared and added to the mixing vessel based on the total weight of the top coat bar. Can be stirred.
메틸트리메톡시실란 및 옥실실란이 준비되면, 혼합용기에 먼저 메틸트리메톡시실란이 투입된다. 메틸트리메톡시실란이 투입되는 혼합용기는 35 내지 45 ℃의 온도가 유지될 수 있다. 혼합용기의 내부에 교반기가 설치될 수 있고 온도 조절을 위한 가열장치 및 냉각장치가 설치될 수 있다. 메틸트리메톡시실란이 혼합 용기에 투입된 이후 메탄올이 혼합용기에 투입되면서 교반이 이루어진다. 메틸트리메톡시실란과 메탄올이 혼합용기에서 교반과 함께 완전히 혼합되면 제2 반응용액이 완성된다(P12). When methyltrimethoxysilane and oxysilane are prepared, methyltrimethoxysilane is first introduced into the mixed container. The mixed vessel into which methyltrimethoxysilane is added may be maintained at a temperature of 35 to 45 ° C. Agitator may be installed inside the mixing vessel, and a heating device and a cooling device for temperature control may be installed. After methyltrimethoxysilane is added to the mixing vessel, methanol is added to the mixing vessel, followed by stirring. When methyltrimethoxysilane and methanol are completely mixed together with stirring in the mixing vessel, the second reaction solution is completed (P12).
제2 반응 용액이 제조되면(P12), 제1 반응 용액이 제2 반응 용액에 첨가될 수 있다(P13). Once the second reaction solution is prepared (P12), the first reaction solution may be added to the second reaction solution (P13).
제1 반응 용액의 첨가량을 중량비율로 제1 반응 용액: 제2 반응 용액 = 1: 2.5~3.2가 될 수 있다. 첨가를 위하여 제1 반응 용액이 수용된 반응용기는 개폐 가능한 밸브가 설치된 관에 의하여 제2 반응 용액이 수용된 혼합용기에 연결될 수 있다. 그리고 제1 반응 용액의 첨가를 위하여 밸브를 개폐하면서 반응용기에 압력 펌프를 이용하여 일정한 압력을 가할 수 있다. 제1 반응 용액은 15 내지 25 Liter/min의 속도로 첨가될 수 있고 첨가과정에서 교반기에 의하여 혼합용액은 계속적으로 교반이 될 수 있다. The amount of the first reaction solution added may be in a weight ratio of 1st reaction solution: 2nd reaction solution = 1: 2.5 to 3.2. The reaction vessel containing the first reaction solution for the addition may be connected to the mixing vessel containing the second reaction solution by a tube provided with an openable valve. And a constant pressure may be applied to the reaction vessel by using a pressure pump while opening and closing the valve for the addition of the first reaction solution. The first reaction solution may be added at a rate of 15 to 25 Liter / min and the mixed solution may be continuously stirred by the stirrer during the addition process.
제1 반응 용액이 제2 반응 용액에 첨가되면, 발열 반응이 진행될 수 있다. 그러므로 혼합 용기는 냉각 장치를 이용하여 일정한 온도 범위로 유지될 필요가 있 고 예를 들어 혼합 용기는 50 내지 70 ℃의 온도로 유지될 수 있다. 제1 반응 용액이 제2 반응 용액에 첨가되어 교반과 함께 혼합이 되고 그리고 완전히 혼합이 된 후 다시 냉각이 되면 상도 코팅 도료의 바인더가 완성된다. 이후 안료 또는 체질 안료와 같은 충진재가 바인더에 첨가되면(P14) 콘크리트 침투 방지를 위한 상도 도료 조성물이 제조된다. When the first reaction solution is added to the second reaction solution, an exothermic reaction may proceed. Therefore, the mixing vessel needs to be maintained at a constant temperature range using a cooling device, for example, the mixing vessel may be maintained at a temperature of 50 to 70 ° C. The first reaction solution is added to the second reaction solution, mixed with stirring, completely mixed and then cooled again to complete the binder of the top coat coating. Then, when a filler such as a pigment or a sieving pigment is added to the binder (P14), a topcoat composition for preventing the penetration of concrete is prepared.
충진재는 예를 들어 펄, 이산화티탄, 산화크롬, 산화철 또는 황연과 같은 것이 있고 상도 코팅 바인더 전체에 대하여 8 내지 15 wt%가 첨가될 수 있다(P14). 충진재는 이 분야에서 공지된 임의의 물질이 될 수 있고 또한 이 분야에서 공지된 다양한 형태의 안료를 포함할 수 있다. 상도 코팅 바인더는 충진재의 첨가에 의하여 페인트 또는 도료가 될 수 있다. The filler may be, for example, pearl, titanium dioxide, chromium oxide, iron oxide or sulfur lead, and may be added in an amount of 8 to 15 wt% based on the entire top coat binder (P14). The filler can be any material known in the art and can also include various types of pigments known in the art. The top coat binder may be paint or paint by the addition of filler.
