Description

2 가지의 바인더를 포함하는 흡착제 코팅용액 및 그 제조방법{ADSORBENT COATING SOLUTION CONTAINING TWO BINDER AND A METHOD OF MANUFACTURING THE SAME}TECHNICAL FIELD [0001] The present invention relates to an adsorbent coating solution containing two kinds of binders,

본 발명은 2 가지의 바인더를 포함한 흡착제 코팅용액에 실리카 나노입자를 포함시킴으로써, 부착력 및 내부식성이 향상되고 수분 흡착능력이 개선되는 흡착제 코팅용액 및 그 제조방법에 관한 것이다.
The present invention relates to an adsorbent coating solution which improves adhesion and corrosion resistance and improves water adsorption ability by including silica nanoparticles in an adsorbent coating solution containing two binders, and a method for producing the same.

일반적으로 흡착제 코팅은 흡착제와 기판과의 부착과 흡착제 입자간의 안정적인 연결을 위해 유기 혹은 무기 바인더를 사용하고 있으며, 사용되는 양은 흡착제 무게비로 약 10% 이상의 많은 양을 차지하고 있다. In general, the adsorbent coating uses an organic or inorganic binder for adhesion between the adsorbent and the substrate and a stable connection between the adsorbent particles, and the amount of the adsorbent is more than about 10% by weight of the adsorbent.

그러나, 유기 바인더를 포함하여 제조할 경우, 피막 조직의 치밀성은 좋으나, 시간이 지남에 따른 친수성에 대한 내구성이 떨어지게 되는 문제점이 발생하게 되어, 흡착제의 수분 흡착능력이 저하된다.However, when an organic binder is included, the denseness of the film structure is good, but the durability against hydrophilicity is deteriorated over time, and the water adsorption ability of the adsorbent is lowered.

한편, 유기 바인더와 무기 바인더를 혼합하여 흡착제 코팅을 제조할 경우, 유기 바인더 또는 무기 바인더만을 사용하여 제조된 코팅 용액의 단점을 어느 정도 보완할 수 있으나, 유기와 무기 바인더가 혼합됨으로 인하여 계면에서 쉽게 열화가 진행될 수 있다.On the other hand, when an adsorbent coating is prepared by mixing an organic binder and an inorganic binder, the disadvantage of a coating solution prepared using only an organic binder or an inorganic binder can be somewhat compensated. However, since the organic and inorganic binders are mixed, Deterioration can proceed.

계면에 열화가 진행됨에 따라 기판과 흡착층의 부착력이 저하되는 문제점이 발생되고, 이물질이나 가스가 흡착되어 친수성이 저하되어, 수분의 흡착능력이 저하된다.As the deterioration progresses at the interface, there is a problem that the adhesion between the substrate and the adsorption layer is lowered, and foreign substances or gases are adsorbed and the hydrophilicity is lowered, and the adsorption ability of water is lowered.

FIG. 1 is a flowchart illustrating a process for preparing an adsorbent coating solution according to an embodiment of the present invention.

도 1에 도시된 바와 같이, 흡착제 코팅용액의 제조방법은 용매에 산을 첨가하여 반응물 혼합용액을 제조하는 혼합용매 제조단계; 상기 혼합용매에 흡착제를 첨가하는 흡착제 분산액 제조단계; 상기 제조된 흡착제 분산액에 2 가지의 바인더를 첨가하는 첨가단계; 및 상기 바인더가 첨가된 흡착제 분산액에 실리카 나노입자를 첨가하는 실리카 나노입자 첨가단계;를 통하여 흡착제 코팅용액이 제조된다.
As shown in FIG. 1, a method for preparing an adsorbent coating solution includes a mixed solvent preparation step of adding an acid to a solvent to prepare a reactant mixture solution; A step of preparing an adsorbent dispersion in which an adsorbent is added to the mixed solvent; An addition step of adding two binders to the prepared adsorbent dispersion; And adding silica nanoparticles to the binder-added adsorbent dispersion to add silica nanoparticles to the adsorbent.

반응물 혼합용액 제조단계는 용매에 산을 첨가하여 반응물을 제조하는 단계이다. The step of preparing the reactant mixed solution is a step of adding the acid to the solvent to prepare the reactant.

여기서, 상기 용매는 물, 알코올, 증류수, 아세톤 중 어느 하나로 제한되지 않으며, 본 발명의 일 실시예에 따른 흡착제 코팅용액은 증류수를 이용하는 것이 바람직하다.Here, the solvent is not limited to any one of water, alcohol, distilled water, and acetone, and it is preferable to use distilled water for the adsorbent coating solution according to an embodiment of the present invention.

또한, 상기 반응물 혼합용액 제조단계에서는 산성 조건에서 반응물을 제조하는데 pH 2 ~ 5 조건에서 제조하는 것이 바람직하다. 이는 반응물이 pH 5 이상에서는 반응물이 겔상태가 되어 흡착제 코팅 용액을 제조하기 어렵고, pH 2 이하의 조건에서는 코팅용액의 점도가 너무 묽어져 두꺼운 코팅층을 형성하기 어려워지기 때문이다. 용매에 첨가되는 산은 중축합 반응을 유도하는 촉매로도 사용되어져 -O-Al-O-, -O-Si-O- 네트워크 구조를 쉽게 형성할 수 있게 하는 역할을 하므로 산성조건에서 반응물을 제조하는 것이 바람직하다.
In addition, in the step of preparing the reactant mixture solution, it is preferable to produce the reactant under acidic conditions at pH 2 to 5. This is because it is difficult to prepare the adsorbent coating solution because the reactant becomes gel state when the reactant is pH 5 or higher, and the viscosity of the coating solution becomes too thin under the condition of pH 2 or less to form a thick coating layer. The acid added to the solvent is also used as a catalyst to induce the polycondensation reaction to easily form the -O-Al-O- and -O-Si-O- network structures, .

흡착제 첨가단계;는 상기 흡착제 코팅용액에서 흡착제를 첨가하는 단계이다. The adsorbent adding step is a step of adding an adsorbent in the adsorbent coating solution.

여기서, 상기 흡착제는 제울라이트, 알루미나겔, 실리카겔 중 어느 하나로 제한되지 않으며, 본 발명의 실시예에서는 실리카겔을 사용하는 것이 바람직하다.
Here, the adsorbent is not limited to any one of zeolite, alumina gel and silica gel, and silica gel is preferably used in the embodiment of the present invention.

상기 흡착제는 상기 흡착제 코팅용액에서 흡착 역할을 하므로 다량으로 첨가되는데, 10 ~ 30 wt% 첨가되는 것이 바람직하다. 이는 첨가되는 흡착제가 10 wt% 미만일 경우에는 첨가되는 흡착제의 양이 적어 흡착제 코팅 두께가 얇아져 수분 흡착 능력이 감소하게 되고, 30 wt%을 초과하여 첨가할 경우에는 바인더의 양에 비하여 첨가되는 흡착제 양이 많아 부착력이 감소하기 때문이다.
The adsorbent may be added in a large amount because it adsorbs in the adsorbent coating solution, and it is preferably added in an amount of 10 to 30 wt%. When the amount of the adsorbent added is less than 10 wt%, the amount of the adsorbent to be added is small, so that the thickness of the adsorbent coating is decreased, and the water adsorption ability is decreased. When the amount of the adsorbent is more than 30 wt% This is because the adhesion is decreased.

2 가지의 바인더 첨가단계는 상기 흡착제가 첨가되어 있는 혼합용매에 두 가지의 바인더를 첨가하는 단계이다. The two binder addition steps are a step of adding two kinds of binders to the mixed solvent to which the adsorbent is added.

여기서, 상기 바인더는 알루미나 바인더와 실리카 바인더를 말한다.Here, the binder refers to an alumina binder and a silica binder.

알루미나 바인더와 실리카 바인더는 상기 흡착 코팅용액에서 흡착제가 안정적으로 기판에 부착되고, 상기 흡착제 입자들끼리 결합을 할 수 있도록 작용한다. 따라서 상기 2 가지의 바인더는 흡착제를 기판위에 안정적으로 코팅 가능하게 해준다.
The alumina binder and the silica binder function to stably attach the adsorbent to the substrate in the adsorption coating solution and to bond the adsorbent particles together. The two binders thus make it possible to stably coat the adsorbent on the substrate.

또한 2 가지의 바인더인 알루미나 바인더와 실리카 바인더 모두 상기 흡착제와 동일한 성분이므로, 흡착제 자체의 수분 흡착능력을 저하시키지 않는다. 또한 상기 2 가지의 바인더는 상기 흡착제를 코팅시킴으로써, 지속적인 수분의 흡착과 탈착을 하는 흡착제 코팅층의 내부식성을 향상시켜, 기판의 부식을 억제하는 효과를 가져온다.
In addition, since both the alumina binder and the silica binder, which are two binders, are the same components as those of the adsorbent, they do not deteriorate the water adsorbing ability of the adsorbent itself. Further, by coating the adsorbent, the two binders improve the corrosion resistance of the adsorbent coating layer which continuously adsorbs and desorbs moisture, and thereby has an effect of suppressing corrosion of the substrate.

첨가되는 알루미나 바인더는 3 ~ 7 wt% , 실리카 바인더는 0.2 ~ 2 wt% 첨가되는 것이 바람직하다. 이는 알루미나 바인더의 경우 3 wt% 미만으로 첨가될 경우, 코팅용액의 점도가 감소하여 흡착제 코팅 두께가 얇아지며 부착력이 감소되고, 7 wt%을 초과하여 첨가할 경우에는 코팅용액의 점도가 과도하게 증가하여 코팅 두께가 두꺼워져 코팅층의 박리 현상이 발생하게 된다.3 to 7 wt% of the alumina binder to be added and 0.2 to 2 wt% of the silica binder are preferably added. When the content of the alumina binder is less than 3 wt%, the viscosity of the coating solution is decreased, the thickness of the adsorbent coating is decreased and the adhesion is decreased. When the content is more than 7 wt%, the viscosity of the coating solution is excessively increased So that the coating thickness becomes thick and the coating layer peels off.

실리카 바인더는 0.2 wt% 미만으로 첨가될 경우, 흡착제 코팅층내 실리카 네트워크 형성이 적어져 내부식성이 감소하게 되고, 2 wt%을 초과하여 첨가할 경우에는 과도한 실리카 네트워크의 형성으로 흡착제와 공기 중 수분의 접촉을 방해하여 수분흡착능력이 감소되기 때문이다.
When the silica binder is added in an amount less than 0.2 wt%, the silica network formation in the adsorbent coating layer is reduced and the corrosion resistance is decreased. When the silica binder is added in an amount exceeding 2 wt%, excessive silica network is formed, This is because the water absorption ability is reduced by interfering with the contact.

첨가된 2 가지의 바인더를 졸-겔 법을 이용하여 가수분해와 중축합 반응을 유도하여 -O-Al-O- 또는 -O-Si-O-의 네트워크 형성시켜, 흡착제 입자끼리의 결합이 이루어지게 된다.
Hydrolysis and polycondensation reaction are induced by the sol-gel method of the two added binders to form a network of -O-Al-O- or -O-Si-O- so that bonding of the adsorbent particles is performed .

실리카 나노 입자 첨가단계는 흡착제와 2 가지의 바인더를 차례로 넣은 혼합용매에 나노입자 형태의 실리카 입자를 첨가하는 단계이다.The step of adding silica nanoparticles is a step of adding silica particles in the form of nanoparticles to a mixed solvent in which an adsorbent and two binders are sequentially placed.

여기서, 실리카 나노입자의 크기는 어느 하나로 제한되지 않으나, 5 ~ 20nm의 크기인 것이 바람직하며, 첨가 시 콜로이드의 상태로 첨가하는 것이 바람직하다.Here, the size of the silica nanoparticles is not limited to any one, but is preferably 5 to 20 nm, and it is preferable to add the silica nanoparticles in a colloidal state when added.

또한, 실리카 나노입자 콜로이드(30 wt% in 에탄올)는 10 ~ 20 wt% 첨가되는 바람직하다.The silica nanoparticle colloid (30 wt% in ethanol) is preferably added in an amount of 10 to 20 wt%.

이는 10 wt%미만일 경우에는 실리카 나노입자의 첨가량이 적어 부착력이 감소하게 되고, 20 wt%을 초과하여 첨가할 경우에는 과도한 첨가로 코팅층의 균열이 잘 발생되기 때문이다.
If it is less than 10 wt%, the adhesion force decreases because the amount of silica nanoparticles to be added is small. When the amount of silica nanoparticles is more than 20 wt%, the coating layer cracks due to excessive addition.

실리카 나노입자는 높은 표면 에너지를 가지고 바인딩 효과가 좋기 때문에, 흡착제 코팅 용액에 첨가 시 실리카겔의 입자간 부착과 실리카겔과 기판의 부착력을 향상시키는 효과를 가져온다. 이는 수십 나노 입자 크기를 가지는 실리카 나노입자는 높은 표면에너지를 가지고 있어 불안정한 상태이므로 서로 붙으려는 특성을 가지기 때문이다. 이러한 특징을 가지고 있기 때문에 수십 나노이하의 작은 입자를 첨가해주면 서로간의 인력이 커져 부착력이 좋아지는 바인딩 효과가 나타나게 된다.
Since the silica nanoparticles have high surface energy and good binding effect, the addition of the silica nanoparticles to the adsorbent coating solution improves the adhesion between the silica gel and the silica gel and the adhesion of the substrate. This is because silica nanoparticles having a size of several tens nanometers have high surface energy and are in an unstable state and therefore have a tendency to stick to each other. When these particles are added to small particles of several tens of nanometers or less, the attractive force between the particles increases, resulting in a strong binding effect.

비교예Comparative Example
