Most of the paints used as the finishing materials are composed of organic compounds and cause environmental pollution problems due to volatile organic compounds (VOCs).

For example, in Korean Patent Registration No. 0564343, titanium dioxide and the like are included as a constituent of a finishing material so that harmful components such as volatile organic compounds are removed by self purification Technology is presented. However, there is a problem that sufficient air purification ability can not be expected even by these techniques.
또한 친환경재료로 황토 등이 마감재의 일조성으로 포함되도록 하는 기술이 제시되고 있으나, 황토 등은 자체활성이 부족하여 피도장물과의 부착력이 저하되는 문제가 있다.
In addition, although a technique of including yellow clay as an eco-friendly material as a single composition of a finishing material has been proposed, there is a problem in that clay or the like has insufficient self-activity and adherence to the object to be coated.
본 발명은 상기와 같은 문제를 해결하기 위하여 안출된 것으로서, 피도장물과 부착력이 우수하고, 공기 정화효율이 우수한 마감재 조성물 및 이의 시공방법을 제공하고자 함이다.

이하, 본 발명의 구성 및 작용을 첨부된 도면에 의거하여 좀 더 구체적으로 설명한다. 본 발명을 설명함에 있어서, 본 명세서 및 청구범위에 사용된 용어나 단어는 발명자가 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.Hereinafter, the structure and operation of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, terms and words used in the present specification and claims are to be construed in accordance with the principles of the present invention, on the basis that the inventor can properly define the concept of a term in order to best explain his invention It should be construed as meaning and concept consistent with the technical idea of.
본 발명의 친환경 마감재 조성물은 물 100중량부에 대해 비닐수지 25 내지 75중량부, 화산재 50 내지 100중량부, 이산화티탄 25 내지 75중량부, 산화규소 25 내지 75중량부, 소포제 0.3 내지 3중량부, 침강방지제 3 내지 15중량부를 포함하여 이루어짐을 특징으로 한다.The eco-friendly finishing composition of the present invention comprises 25 to 75 parts by weight of vinyl resin, 50 to 100 parts by weight of volcanic ash, 25 to 75 parts by weight of titanium dioxide, 25 to 75 parts by weight of silicon oxide, 0.3 to 3 parts by weight of defoaming agent, And 3 to 15 parts by weight of a sedimentation inhibitor.
즉 본 발명에서는 산업폐기물의 일종인 화산재가 조성으로 배합됨으로써 화산재에 함유된 활성실리카(soluble silica) 성분이 피도장물로서 특히 콘크리트에 적용되는 경우 콘크리트의 수산화칼슘과 화학적으로 반응하여 부착강도와 내구성이 우수한 장점이 발현되는 것이며, 이러한 산업폐기물을 재활용함으로써 친환경적인 장점이 있는 것이다.That is, in the present invention, when the volatile matter, which is one kind of industrial waste, is blended into the composition, the soluble silica component contained in the volcanic ash is chemically reacted with the calcium hydroxide of the concrete, It is a good advantage, and it is environment-friendly by recycling these industrial wastes.
여기서 상기 비닐수지는 천연 비닐수지가 배합되는 것이 타당한 바, 이러한 비닐수지는 기계적 강도의 증진을 위하여 바인더로서 첨가되는 것으로서 상기와 같은 한정범위로 배합하는 것이 경험칙상 부착강도를 향상시킴을 알 수 있어 상기와 같은 배합범위로 한정하는 것이다.It is proper that the vinyl resin is blended with a natural vinyl resin. Such a vinyl resin is added as a binder for the purpose of enhancing the mechanical strength, And is limited to the mixing range as described above.
상기 이산화티탄은 광촉매로서 배합되는 것으로, 이러한 이산화티탄은 자외선에 의해 스스로 광산화 작용을 나타내고, 가스 등 2차 오염 부산물을 방출하지 않으며, 특히 유기물에 대한 강력한 산화환원 작용으로 정화작용이 이루어지도록 하는 것이다. 이러한 이산화티탄을 상기와 같은 배합범위로 한정하는 이유는 상기 배합범위를 초과하는 경우 이산화티탄의 광산화반응으로 인해 피도장물 자체에 손상이 있을 수 있어 상기와 같이 한정하는 것이다.The titanium dioxide is blended as a photocatalyst. The titanium dioxide itself exhibits a photo-oxidation effect by ultraviolet rays and does not emit secondary pollution by-products such as gas. Particularly, . The reason why the titanium dioxide is limited to the above-mentioned blending range is that if the blending range is exceeded, the coated object itself may be damaged due to the photo-oxidation reaction of the titanium dioxide, so that the limitation is as described above.
그런데 상기 이산화티탄만을 배합하는 경우에는 우기, 음지 등에 광조사량이 부족할 시 자기정화의 기능이 제대로 구현될 수 없는 문제가 있다. 이러한 자기정화화 기능이 제대로 구현되지 않는 경우 각종 인체에 유해한 유기물 등이 배출되며, 마감재에 이끼, 곰팡이 등이 번식하여 2차 오염이 유발되는 문제가 있다.However, in the case of mixing only the titanium dioxide, there is a problem that the function of self-purification can not be realized when the amount of light irradiation is insufficient in the wet season and the shade. If such a self-purification function is not properly implemented, there is a problem that harmful organic substances and the like are discharged to the human body, moss and mold propagate in the finishing material and secondary pollution is caused.
이에 본 발명에서는 이산화티탄에 더하여 산화 알루미늄이 더 배합되도록 하는 바, 상기 산화 알루미늄은 물 100중량부에 대해 25 내지 75중량부가 배합되도록 하는 것이다. 상기 산화 알루미늄은 축광안료로서 배합되는 것으로, 우기 등에 있어 광조사량이 부족할 시에 잔광에 의해 상기 이산화티탄의 자기정화 기능이 계속적으로 구현되도록 하는 것이다.In the present invention, in addition to titanium dioxide, aluminum oxide is further blended so that the aluminum oxide is blended in an amount of 25 to 75 parts by weight with respect to 100 parts by weight of water. The aluminum oxide is blended as a phosphorescent pigment so that the self-purification function of the titanium dioxide can be continuously realized by afterglow when the light irradiation amount is insufficient in the wet season or the like.
상기 산화 알루미늄은 스피넬(Spinel) 구조를 갖는 것으로서 인체에 유해한 방사선의 방출이 없고, 장시간의 발광시간(잔광시간 최대 2,000분)을 가지며, 우수한 내후성을 갖는 조성이다.The aluminum oxide has a spinel structure and is a composition having no emission of harmful harmful substances to the human body, having a long luminescence time (maximum afterglow time of 2,000 minutes) and having excellent weather resistance.
즉 상기 산화 알루미늄은 광조사량이 부족할 시에 잔광을 이용해 상기 이산화티탄의 자기정화능이 계속적 발현을 보완하도록 하는 구성이다.That is, the aluminum oxide has such a constitution as to complement the continuous expression of the self-cleaning ability of the titanium dioxide by using afterglow when the light irradiation amount is insufficient.
상기 산화 알루미늄은 25중량부 미만으로 배합되는 경우 잔광효과를 기대할 수 없으며, 75중량부를 초과하는 경우 강도저하, 타 조성과의 안정된 분산이 어려운 문제가 있어 상기와 같이 한정한다.When the amount of the aluminum oxide is less than 25 parts by weight, a afterglow effect can not be expected. When the amount of the aluminum oxide exceeds 75 parts by weight, the strength is lowered and stable dispersion with other compositions is difficult.
한편 한여름 등 기온이 높을 시에 마감재와 피도장물 사이에는 열팽창률이 다르며 일반적으로 마감재의 열팽창율이 높아 이에 따른 균열발생의 문제가 빈번하게 발생한다. 또한 마감재의 일 조성으로 배합되는 이산화티탄은 타 조성과 배합됨에 따라 타 조성에 가리거나 균일한 분산이 되지 않는 이유 등으로 외부로부터의 광조사량을 충분히 흡수할 수 없는 문제가 있다.On the other hand, when the temperature is high, such as during the summer, the coefficient of thermal expansion between the finishing material and the object to be coated is different. Generally, the thermal expansion rate of the finishing material is high. Further, titanium dioxide mixed with one composition of the finishing material has a problem that it can not sufficiently absorb light irradiation amount from the outside because it is mixed with other composition and is not covered with other composition or is not uniformly dispersed.
이에 본 발명에서는 스트론튬 알루미네이트가 더 배합되도록 하는 바, 상기 스트론튬 알루미네이트는 열에너지에 노출되는 경우 핵 주위를 도는 전자가 열에너지에 의하여 들뜬 상태로 가면서 열에너지를 흡수하고 전자의 안정화 경향에 따라 빛 에너지로 방사하면서 다시 원상태로 복귀하는 성질을 가진다. 즉 상기 스트론튬 알루미네이트는 열에너지를 빛에너지로 전환하여 방사함으로써 방열기능을 수행하도록 하는 것이다.In the present invention, strontium aluminate is further compounded. When the strontium aluminate is exposed to heat energy, electrons circulating around the nucleus are excited by heat energy and absorb heat energy. As a result of stabilization of electrons, And has the property of returning to the original state after radiation. That is, the strontium aluminate converts heat energy into light energy and radiates it to perform a heat radiation function.
이러한 스트론튬 알루미네이트가 배합되어 마감재에 발생된 열을 빛으로 전환하여 방열기능을 하도록 하는 것으로 방열에 의해 마감재의 열팽창을 방지함과 동시에 방열과정에서 전환된 빛은 상기 이산화티탄으로의 광조사량을 크게 하여 자기정화능이 극대화 되도록 할 수 있는 것이다. The strontium aluminate is mixed to convert the heat generated in the finishing material into light so as to function as a heat radiation function, thereby preventing thermal expansion of the finishing material due to heat radiation, and at the same time, So that the self-purification ability can be maximized.
즉 내부 조성으로서 이산화티탄과 같이 배합되는 스트론튬 알루미네이트에 의해 방열과정에서 발생하는 빛이 이산화티탄에 조사되도록 하여 이산화티탄은 외부 및 내부로부터 광조사가 되어 자기정화능이 극대화 되도록 하는 것이다.That is, the light generated in the heat dissipation process is irradiated to the titanium dioxide by the strontium aluminate compounded with the titanium dioxide as the internal composition, so that the titanium dioxide is irradiated from the outside and the inside to maximize the self-purification ability.
상기 스트론튬 알루미네이트는 물 100중량부에 대해 25중량부 내지 75중량부가 배합되도록 하는 것이 타당한데, 25중량부 미만이면 방열기능과 광조사기능의 발현이 미미하고 75중량부를 초과하는 경우 타 조성과의 균일한 분산이 어려우며 강도를 저하시키는 문제가 있어 이와 같이 한정하는 것이다.It is appropriate that the strontium aluminate is blended in an amount of 25 to 75 parts by weight with respect to 100 parts by weight of water. When the amount of the strontium aluminate is less than 25 parts by weight, the heat radiation function and the light irradiation function are insufficient. Is difficult to be uniformly dispersed and the strength is lowered.
상기 산화규소는 마감재의 강도를 강화시키기 위한 것임과 동시에 난연제로서 기능을 하도록 첨가되는 것이다. 상기 산화규소는 물 100중량부에 대해 25 내지 75중량부로 배합되는 것이 타당한 바, 이는 25중량부 미만이면 상기에서 언급한 효과의 발현이 미미하고, 75중량부를 초과하는 경우 유동성 저하로 작업성이 저하되는 문제가 있어 이와 같이 한정하는 것이다.The silicon oxide is added to enhance the strength of the finish and also to function as a flame retardant. It is appropriate that the silicon oxide is blended in an amount of 25 to 75 parts by weight with respect to 100 parts by weight of water. If the amount of the silicon oxide is less than 25 parts by weight, the above-mentioned effect is not sufficiently manifested. When the amount exceeds 75 parts by weight, There is a problem that it is deteriorated.
상기 소포제는 마감재 내부에서 기포를 제거하는 것으로서, 휘발성이 적고 확산력이 큰 수용성의 계면활성제가 사용됨이 타당하다.The antifoaming agent removes air bubbles from the inside of the finishing material, and it is proper to use a water-soluble surfactant having a low volatility and a high spreading power.
상기 침강방지제는 마감재의 평활도를 유지하기 위해 첨가되는 것으로 다양한 침강방지제가 사용될 수 있으며, 예로 아크릴계가 사용될 수 있다.The anti-settling agent is added to maintain the smoothness of the finishing material, and various anti-settling agents may be used, for example, an acrylic type may be used.
더욱 바람직하게 상기에서 언급한 조성외에도 물 100중량부에 대해 프로필렌 카보네이트 0.3 내지 3 중량부가 더 배합되도록 할 수 있는 바, 상기 프로필렌 카보네이트가 더 배합됨에 따라 마감재에서 이산화티탄, 산화 알루미늄 및 스트론튬 알루미네이트 등이 전체에 걸쳐 균일하게 분산되도록 함으로써 마감재 전체에서 균일한 정화작용 및 방열이 수행되도록 할 수 있다.More preferably 0.3 to 3 parts by weight of propylene carbonate can be added to 100 parts by weight of water in addition to the above-mentioned composition. As the propylene carbonate is further blended, titanium dioxide, aluminum oxide and strontium aluminate So that uniform cleaning action and heat radiation can be performed in the entire surface of the finish material.
더욱 바람직하게 상기 조성에 더하여 물 100중량부에 대해 옥타데칸, 스테아르산 중 하나 또는 혼합물이 0.3 내지 3중량부가 더 배합되도록 할 수 있다. 이렇게 첨가하는 이유는 옥타데칸, 스테아르산이 상변이물질로서 일정한 상전이온도(phase transition temp)에서 상변화에 필요한 열량을 외부에서 흡수하는 특성을 지니는 것으로, 본 발명의 마감재에 첨가되는 경우 주위 기온이 높아짐에 따라 상기 물질이 상전이온도에 도달하게 되면 물리적인 상변화에 의해 열을 흡수함으로써 마감재의 열을 저감시키도록 하여 열팽창에 의해 균열이 발생되는 것을 방지하고자 하는 것이다.More preferably, 0.3 to 3 parts by weight of one or a mixture of octadecane and stearic acid may be further blended with 100 parts by weight of water in addition to the above-mentioned composition. The reason for this addition is that octadecane or stearic acid is a phase-change foreign material and has a property of externally absorbing a heat amount required for a phase change at a certain phase transition temp. When added to the finish material of the present invention, Accordingly, when the material reaches the phase transition temperature, heat is absorbed by the physical phase change to reduce heat of the finishing material, thereby preventing cracks from being generated due to thermal expansion.
한편 본 발명의 시공방법은 상기 친환경 마감재 조성물을 피도장물에 도장하는 것으로 우선 피동장물에 있어 도장면을 전처리 하는 단계를 갖는다. 여기서 전처리는 도장면의 표면에 먼지, 수분, 이물질을 제거하는 것을 말한다.Meanwhile, the method of the present invention has a step of pretreating a coated surface in a driven article by coating the coated article with the environmentally friendly finishing composition. Here, pretreatment refers to the removal of dust, moisture, and foreign matter on the surface of the coated surface.
특히 본 발명에서는 상기 피도장물이 콘크리트 구조물의 경우 인산 1 내지 3% 수용액을 이용하여 콘크리트면을 중화처리하는 전처리 단계를 포함한다. 인산 1 내지 3% 수용액을 이용하는 이유는 알카리화 된 콘크리트면을 중화시키기 위한 것으로 도장되는 마감재와의 부착력을 향상시키기 위한 것이다.Particularly, in the present invention, in the case of the concrete structure, the pretreatment step of neutralizing the concrete surface by using 1 to 3% aqueous solution of phosphoric acid. The reason for using a 1 to 3% aqueous solution of phosphoric acid is to neutralize the alkalized concrete surface and to improve the adhesion with the coating material to be painted.
여기서 인산 용해량이 상기 범위를 초과하면 콘크리트면만을 중화시켜야 하는데 내부까지 중화시켜 콘크리트 열화의 원인이 될 수 있으므로 상기와 같은 범위로 한정하는 것이다.If the amount of phosphoric acid dissolution exceeds the above range, only the concrete surface should be neutralized, and neutralization to the inside of the concrete may cause deterioration of concrete. Therefore, the range is limited to the above range.
이렇게 전처리 후에는 붓, 로라, 에어레스 스프레이 등 도장공구를 한정하지 않고 상기 피도장물에 마감재를 시공하는 것이다.After the pretreatment, the finish material is applied to the object to be coated without limiting paint tools such as a brush, a roller and an airless spray.
이상 설명한 내용을 통해 당업자라면 본 발명의 기술사상을 일탈하지 아니하는 범위에서 다양한 변경 및 수정 가능함을 알 수 있을 것이다. 따라서, 본 발명의 기술적 범위는 명세서의 상세한 설명에 기재된 내용으로 한정되는 것이 아니라 특허청구범위에 의해 정해져야만 할 것이다.
