Abstract
Description
본 발명은 탄성기능을 갖는 단열 도료 조성물에 관한 것으로, 특히 인슐래드(INSULADD)가 첨가된 도료로서 건축물의 외벽에 도포되어 우수한 단열 기능은 물론 탄성기능을 보유하여 방수성과 내구성은 물론 방오성과 부착성을 향상시킨 탄성기능을 갖는 단열, 차열 도료 조성물에 관한 것이다.
The present invention relates to an insulating coating composition having an elastic function, and in particular, as an insulating coating (INSULADD) is applied to the outer wall of the building to have excellent heat insulating function, as well as elastic function, waterproof and durable as well as antifouling and adhesion The present invention relates to a heat insulating and heat shielding coating composition having improved elastic function.
각종 건축물의 옥상, 외벽, 터널, 지하실 등의 표면에는 방수 또는 방식 도막을 형성하는 것이 일반적이다. It is common to form a waterproof or anticorrosion coating on the surface of roofs, outer walls, tunnels, basements, etc. of various buildings.
또한, 선박이나 철재 구조물에는 방식 도막을 형성한다. In addition, an anticorrosive coating film is formed on a ship or a steel structure.
방수 또는 방식 도막은 피착체에 충분히 접착하여 수밀성이 확보되어야 하며, 하절기와 동절기의 온도 차이에 의한 부피변형을 충분히 견딜 수 있도록 유연성이 부여되어야 한다. The waterproof or anticorrosive coating film should be sufficiently adhered to the adherend to ensure watertightness, and should be flexible enough to withstand the volume deformation caused by the temperature difference between summer and winter.
뿐만 아니라, 최근 환경 및 안전성에 대한 문제가 강조됨에 따라, 친환경적이면서 난연성 등의 기능도 부여되어야 한다.In addition, as environmental and safety issues are recently emphasized, eco-friendly and flame retardant functions should be provided.
방수 또는 방식 도막의 형성공법으로서 유기 에멀젼을 이용한 탄성도막 방수제를 피착층에 도포하는 방법이 일반적으로 사용되어 왔다. As a method for forming a waterproofing or anticorrosive coating film, a method of applying an elastic coating waterproofing agent using an organic emulsion to an adhered layer has been generally used.
이러한 탄성도막 방수제는 초산비닐수지 공중합체를 포틀란트 시멘트나 규사와 일정 비로 혼합하여 제조된다. Such an elastic coating waterproofing agent is prepared by mixing a vinyl acetate resin copolymer with portland cement or silica sand in a predetermined ratio.
초산비닐계 수지는 내수성이 약하므로 건물이 오랫동안 지속적인 수분의 영향을 받게 되면, 시공 당시의 피착제에 대한 접착성을 계속 유지하지 못하고 박리되므로서 누수를 일으키게 된다. 특히 이와 같은 종래의 고분자 무기질계 탄성도막 방수제를 이용하여 옥상 바닥에 방수 또는 방식 도막을 형성하는 경우, 콘크리트면과 도막 사이의 접착부위에 작용하는 수증기압 때문에 기온이 상승하는 여름철에는 이와 같은 박리 현상이 더욱 심해진다.Since vinyl acetate-based resin is weak in water resistance, if the building is subjected to continuous moisture for a long time, water leakage occurs due to peeling without maintaining adhesion to the adherend at the time of construction. In particular, when the water-resistant or anticorrosive coating film is formed on the roof floor using the conventional polymer inorganic elastic coating waterproofing agent, such peeling phenomenon occurs during the summer when the temperature rises due to the water vapor pressure acting on the adhesive part between the concrete surface and the coating film. It gets worse.
또한, 종래의 무기질계 탄성도막 방수제만을 이용하여 방수 또는 방식 도막을 형성하는 것만으로는 도막에 단열성과 난연성의 기능을 부여하는 것이 용이치 않고 그 효율도 저하된다는 문제점이 있다. In addition, merely forming a waterproof or anticorrosive coating film using only a conventional inorganic type elastic coating waterproofing agent has a problem in that it is not easy to impart heat insulating and flame retardant functions to the coating film, and the efficiency thereof is also lowered.
이를 개선하기 위한 일환으로, 공개특허 제2005-0000816호에는 도막층에 난연 및 단열성능을 부여하기 위하여 다공성 세라믹과 인계 난연제를 첨가한 탄성도막 방수제를 이용하여 2층 이상 도포하여 형성한 방수 또는 방식 도막의 형성공법이 개시되어 있다.As part of improving the problem, Patent Publication No. 2005-0000816 discloses waterproofing or anticorrosion formed by applying two or more layers using an elastic coating waterproofing agent added with a porous ceramic and a phosphorus-based flame retardant to impart flame retardant and insulating properties to the coating layer. A method of forming a coating film is disclosed.
그러나, 전술한 공개특허에 개시된 바와 같이, 단열물질 및 난연물질을 각 도포층에 모두 첨가하는 경우, 목적하는 정도의 난연 또는 단열성능을 부여하기 위해서는 첨가량이 지나치게 많아져서 비경제적이며, 탄성이나 내구성 등 형성되는 도막의 물성을 저하시킬 우려가 있다.However, as disclosed in the above-mentioned Patent Publication, when both the heat insulating material and the flame retardant material are added to each coating layer, in order to impart the desired degree of flame retardant or heat insulating performance, the amount of addition is too large to be uneconomical, and the elasticity and durability There is a risk of deteriorating the physical properties of the coating film formed.
이를 개선한 예, 등록특허 제0564909호가 개시되어 단열 방수 탄성도막을 제공하고는 있으나, 주로 난연성에 촛점이 맞추어져 있어 방오성과 부착성은 떨어지는 단점이 있어 개선의 필요가 있었다.
An example of improving this, Patent No. 0564909 has been disclosed to provide a heat-insulating waterproof elastic coating film, but mainly focused on flame retardancy, there is a disadvantage in that stain resistance and adhesion is inferior, there was a need for improvement.
본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점들을 감안하여 이를 해결하고자 창출된 것으로, 인슐래드(INSULADD)가 첨가된 도료로서 건축물의 외벽에 도포되어 우수한 단열, 차열 기능은 물론 탄성기능을 보유하여 방수성과 내구성은 물론 방오성과 부착성을 향상시킨 탄성기능을 갖는 단열 도료 조성물을 제공함에 그 주된 목적이 있다.

However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
본 발명에 따른 도료 조성물은 중량%로, 이산화티탄:10-15%, 탄산칼슘:2-6%, 디메틸폴리실록산:5-10%, 인슐래드:10-15%, 소포제:0.05-0.1%, 분산제:0.1-0.5%, 방부제:0.05-0.2%, 증점제:2-4% 및 나머지 아크릴에멀젼;으로 이루어진다.The coating composition according to the present invention is in weight percent, titanium dioxide: 10-15%, calcium carbonate: 2-6%, dimethylpolysiloxane: 5-10%, insulation: 10-15%, antifoaming agent: 0.05-0.1%, dispersant : 0.1-0.5%, preservative: 0.05-0.2%, thickener: 2-4%, and the remaining acrylic emulsion.
이때, 상기 도료 조성물 100중량부에 대해 프로필렌글리콜(Propylene Glycol):5-10중량부를 더 첨가하여 아크릴에멀젼이 쉽게 응집되지 않도록 하여 동결 방지기능을 더욱 더 강화시킬 수 있다.At this time, the propylene glycol (Propylene Glycol): 5-10 parts by weight may be added to 100 parts by weight of the coating composition to prevent the acrylic emulsion from easily agglomerated to further enhance the freezing prevention function.
또한, 상기 도료 조성물 100중량부에 대해 안티몬주석화합물:10-15중량부를 더 첨가하여 열차단을 통한 단열 기능을 더욱 배가시킬 수 있다.In addition, by adding an antimony tin compound: 10-15 parts by weight based on 100 parts by weight of the coating composition may further double the heat insulating function through the thermal barrier.
특히, 상기 안티몬주석화합물은 이산화티탄과의 결합에 의해 광촉매 기능 활성 및 그에 따른 방오성을 촉진하는 특성도 갖는다.In particular, the antimony tin compound also has a property of promoting photocatalytic function activity and antifouling properties by binding to titanium dioxide.
뿐만 아니라, 상기 안티몬주석화합물은 증류수 30 중량%와 1,4-butanediol 30 중량%를 섞은 후, 가성소다(NaOH)를 이용하여 pH=11로 조절한다. 여기에 사염화주석(SnCl4·5H2O)을 37 중량%와 삼염화안티몬(SbCl3) 3 중량%를 첨가하여 균일하게 혼합될 수 있도록 초음파로 분산시킨 후 이 혼합물을 가압반응기(Autoclave)에 넣고 결정화를 위해 질소분위기에서 300 ℃까지 5 ℃/min 속도로 승온시킨 후, 4시간 유지시켜 20 nm 크기를 갖도록 제조하는 것이 바람직하다.In addition, the antimony tin compound is mixed with 30% by weight of distilled water and 30% by weight of 1,4-butanediol, and then adjusted to pH = 11 using caustic soda (NaOH). 37% by weight of tin tetrachloride (SnCl 4 · 5H 2 O) and 3% by weight of antimony trichloride (SbCl 3 ) were dispersed by ultrasonic so as to be uniformly mixed, and the mixture was placed in an autoclave. In order to crystallize, it is preferable to increase the temperature to 5 ° C./min up to 300 ° C. in a nitrogen atmosphere, and then maintain it for 4 hours to prepare a 20 nm size.
이때, 특성 발현을 위해 가장 중요한 요소는 안티몬과 주석의 비율인데, 안티몬과 주석을 몰비로 1.5:8.5~0.5:9.5 사이로 조정하는 것이다.At this time, the most important factor for the expression of the properties is the ratio of antimony and tin, it is to adjust the antimony and tin in the molar ratio between 1.5: 8.5 ~ 0.5: 9.5.
아울러, 상기 도료 조성물 중 소포제, 분산제, 방부제, 증점제 등은 당해 분야에서 통상적으로 사용되는 것으로, 대부분 소량 첨가되는데, 이를 테면 소포제는 도료를 도포한 후 기포에 의해 생기는 핀홀(pin hole)을 방지하여 표면을 평활하게 유지하기 위해 첨가되는 것으로 알코올 또는 유기인산염이 바람직하며, 분산제는 도료의 제조공정에서 첨가물의 분산을 쉽게 하기 위해 첨가되는 것으로 통상 각종 계면활성제가 대부분이고, 방부제는 부패를 방지하거나 억제하기 위한 것으로 메틸파라벤이 바람직하며, 증점제는 점도를 조절하기 위한 것으로 마그네슘이나 실리케이트 등의 점토광물과 같은 무기증점제가 바람직하다.In addition, defoamers, dispersants, preservatives, thickeners, etc. in the coating composition are commonly used in the art, most of them are added in small amounts, such as antifoaming agent to prevent the pin hole (pore) caused by bubbles after applying the paint The alcohol or organophosphate is preferably added to keep the surface smooth, and the dispersant is added to facilitate the dispersion of the additive in the manufacturing process of the paint. In general, various surfactants are used, and preservatives prevent or inhibit rot. Methylparaben is preferred for this purpose, and the thickener is for controlling viscosity, and inorganic thickeners such as clay minerals such as magnesium and silicate are preferable.
따라서, 이들 소포제, 분산제, 방부제, 증점제 등은 기능성 첨가제이며, 당해 분야에서 통상적으로 소량 범위 내에서 사용하는 것이므로 본 발명에서도 이들이 특별한 성분으로서 특징을 갖는 것은 아니다.Therefore, these antifoaming agents, dispersing agents, preservatives, thickeners and the like are functional additives, and since they are usually used in a small amount in the art, they do not have characteristics as special components in the present invention.
그리고, 상기 이산화티탄(R TiO2)은 표백 및 색상을 밝게 하기 위해 첨가되는 것으로, 주로 백색안료와 광촉매로 사용되고, 사용업체에서는 보통 '지당'이라 칭한다.In addition, the titanium dioxide (R TiO 2 ) is added to brighten bleaching and color, and is mainly used as a white pigment and a photocatalyst, and is commonly referred to as 'fat sugar' by the user.
이러한 이산화티탄은 화학적으로 굉장히 안정되어 있고 인체에도 무해하며, 하얀 분말가루로 이루어져 있고, 플라스틱, 도료, 약품, 종이, 도기 등 거의 전분야에 걸쳐서 광범위하게 사용된다.Titanium dioxide is chemically very stable and harmless to the human body, made of white powdered powder, widely used in almost all fields such as plastic, paint, medicine, paper, pottery.
특히, 형태에 따라 아나타제와 루타일로 구분되는데, 아나타제를 A 이산화티탄, 루타일을 R 이산화티탄이라 하며, 본 발명에서는 R 이산화티탄을 사용한다.In particular, depending on the form is divided into anatase and rutile, anatase A titanium dioxide, rutile is called R titanium dioxide, in the present invention uses R titanium dioxide.
본 발명에서 첨가되는 R 이산화티탄은 분말형태로 배합되며, 10중량% 미만으로 첨가되면 표백 및 색상 구현이 어렵고, 15중량%를 초과하면 과표백이 일어나 색상 불량 및 불균형을 유발하므로 상기 범위로 한정하여 배합하여야 한다.R titanium dioxide added in the present invention is formulated in the form of powder, when added in less than 10% by weight is difficult to implement bleaching and color, and exceeds 15% by weight because of overbleaching causes color defects and imbalances limited to the above range It must be formulated.
뿐만 아니라, 탄산칼슘은 접착력을 강화하고 도막을 형성하여 두께를 조절하여 줌으로써 내부가 보이는 현상을 억제하기 위해 첨가되는 것으로 2~6중량% 첨가되는 것이 바람직하다.In addition, the calcium carbonate is preferably added in order to suppress the phenomenon of the inside visible by strengthening the adhesion and forming a coating film to adjust the thickness is preferably added 2 to 6% by weight.
이때, 6중량%를 넘어 과하게 첨가될 경우 탄성기능을 저하시키며, 2중량% 미만으로 첨가되면 접착력이 약화되므로 상기 범위로 한정되어야 한다.At this time, when added in excess of 6% by weight lowers the elastic function, if less than 2% by weight should be limited to the above range because the adhesive strength is weakened.
아울러, 상기 디메틸폴리실록산(Dimethyl Polysiloxane)은 도막 형성시 대류현상이나 표면장력 차이에 의해 발생하는 유전성의 결점에 의해 붓자국, 오렌지 필 등을 개선하고, 도막의 긁힘은 막으면서 슬립성은 높일 수 있도록 첨가된다.In addition, the dimethyl polysiloxane (Dimethyl Polysiloxane) is added to improve the brush marks, orange peel, etc. due to the dielectric defects caused by the convection phenomenon or surface tension difference when forming the coating film, and to prevent the scratches of the coating film to increase the slip properties do.
이를 위해, 상기 디메틸폴리실록산은 5-10중량% 범위로 첨가되어야 하는데, 5중량% 미만으로 첨가되면 슬립성이 떨어져 방오성을 얻을 수 없고, 10중량%를 초과하면 점성을 떨어뜨리므로 상기 범위로 한정되어야 한다.To this end, the dimethylpolysiloxane should be added in the range of 5-10% by weight, but if added in less than 5% by weight, slip resistance is not obtained, antifouling properties cannot be obtained, and if it exceeds 10% by weight, the viscosity is limited to the above range. Should be.
그리고, 상기 인슐래드는 알루미늄 실리게이트를 주성분으로 하여 마이크론 크기의 미세한 중공체분말로서 폐쇄 공기층의 열차폐 열반사와 열저항을 갖는 유해 중금속은 물론 휘발성 유기화합물및 독성이 전혀 없는 환경 친화적인 소재이다.In addition, the insulation is a micron-sized hollow hollow powder mainly composed of aluminum silicide, and is an environmentally friendly material having no harmful heavy metals having heat shielding and heat resistance of a closed air layer, as well as volatile organic compounds and toxicity.
내구성과 열저항성이 우수하고, 특히 태양복사열 차단성능이 우수하여 미항공우주국에서 우주왕복선 표면 도포제로 활용되고 있다.It has excellent durability and heat resistance, and in particular, it has excellent solar radiation heat shielding performance and is used as a surface shuttle coating agent in NASA.
다만, 미소 분말형태이기 때문에 도료 조성물 구성시 균일한 분산성이 매우 중요한데, 이를 위해 충분한 교반과 함께 앞서 설명한 분산제를 적절히 조절 투입하여야 한다.However, since it is in the form of a fine powder, uniform dispersibility is very important when constructing the coating composition. For this purpose, the dispersant described above should be appropriately controlled and added with sufficient agitation.
특히, 상기 인슐래드는 독립된 공동으로 된 구, 즉 폐쇄된 셀 구조를 가져 내부에 진공을 형성하는 구조적 특성상 내구성 및 온도저항성이 높고, 습기침입에 강한 저항성을 가질 뿐만 아니라 표면에 기밀성이 강한 표피를 형성하여 내수성 및 내습성이 강한 단열층을 형성하며, 산과 알칼리에 아주 강한 효능을 가지고 있어 내화학성도 우수하고, 주재료 및 분자구조가 화학적으로 매우 안전한 구조를 지니고 있어 수명이 반영구적이며, 실험에 따르면 항곰팡이성도 우수한 것으로 확인되었다.In particular, the insulation has a sphere made of an independent cavity, that is, a closed cell structure to form a vacuum therein, and thus has a high durability and temperature resistance, a resistance to moisture intrusion, and an airtight skin on the surface. As a result, it forms a heat-insulating layer with strong water resistance and moisture resistance, has a very strong effect on acids and alkalis, has excellent chemical resistance, and the main material and molecular structure have a chemically very safe structure, and its life is semi-permanent. It was confirmed that the superiority.
본 발명에서는 이와 같은 인슐래드의 장점을 확인하고, 다른 항균성분인 규불화마그네슘과의 관계 및 결로방지 강화를 위해 첨가되는 후술되는 규조도의 성분 비율을 고려하여 10-15중량%로 첨가되어야 한다.In the present invention, it should be added to 10-15% by weight in consideration of the advantages of such an insulation, in consideration of the relationship between the other antimicrobial component magnesium silicate and the component ratio of the diatomity to be added to enhance the condensation prevention.
상기 인슐래드가 10중량% 미만으로 첨가되면 항곰팡이성 및 결로방지성이 떨어지고, 15중량%를 초과하여 첨가되면 혼합성과 윤활성이 떨어지므로 상기 범위로 한정되어야 한다.If the insulation is added less than 10% by weight, anti-mildew and condensation-resistant properties are inferior, when added in excess of 15% by weight should be limited to the above range because of poor mixing and lubricity.
마지막으로, 남은 성분으로 첨가되어 비율을 조절하는 상기 아크릴 에멀젼은 공기층 형성 및 탄성도막 효과를 얻기 위해 1~2㎛의 입도를 갖는 미립자가 바람직하다.Finally, the acrylic emulsion added to the remaining ingredients to adjust the ratio is preferably fine particles having a particle size of 1 ~ 2㎛ to obtain the air layer formation and elastic coating effect.
특히, 상기 아크릴 에멀젼은 액상의 단열 도막제가 건조되면서 여러 겹의 공기층을 형성할 때 이 공기층이 일종의 복층유리(Fair Glass)와 같은 공기단열층을 여러 겹 형성하는 효과를 나타내어 얇은 도막으로도 우수한 단열 효과 및 탄성력을 얻을 수 있다.In particular, the acrylic emulsion has the effect of forming multiple layers of air insulation layers such as a kind of a pair of glass (Fair Glass) when the liquid insulating heat-insulating film is dried to form a plurality of layers of air, excellent thermal insulation effect even with a thin coating film And an elastic force can be obtained.
이와 같은 성분 조성으로 이루어진 본 발명에 따른 도료 조성물은 충분히 혼합 교반된 상태로 건축물의 외벽에 도포되면 단열성능을 가지면서도 방오성을 지닌 탄성도막으로서 역할을 충분히 수행할 수 있게 된다.
