Abstract
Description
본 발명은 차열 및 방수기능을 통한 콘크리트의 수명향상 효과를 나타내는 도료 조성물에 관한 것으로, 더욱 상세하게는 콘크리트의 중성화를 방지하며, 방수성을 부여할 뿐만 아니라, 열과 자외선 차단효과가 우수하여 콘크리트의 수명을 향상시키는 도료 조성물에 관한 것이다.The present invention relates to a paint composition exhibiting an effect of improving the lifespan of concrete through heat shielding and waterproofing functions, and more particularly, to a paint composition that prevents neutralization of concrete, imparts waterproofness, and has excellent heat and ultraviolet blocking effects, thereby increasing the lifespan of concrete. It relates to a paint composition that improves.
콘크리트 구조물은 외부적인 원인에 의해 열화가 진행되는데, 즉, 온도변화, 계절변화에 따른 동결융해, 강우, 습도 및 대기상태 변화와 같은 환경적인 요인이 주된 원인이며, 중성화, 염화물 침해, 철근부식, 동결용해, 황산침해 및 알칼리골재 반응 등의 요인도 하나의 원인이 되고 있다.Concrete structures are degraded by external causes, that is, environmental factors such as temperature change, freezing and thawing according to seasonal changes, rainfall, humidity, and atmospheric conditions are the main causes. Freeze-thawing, sulfuric acid attack, and alkali aggregate reaction are also contributing factors.
상기에 기재된 콘크리트의 열화 요인들은 단독 또는 복합적으로 작용하여 수분이나 기타 외부 유해물질들이 콘크리트 내부로 침투하여, 콘크리트 자체를 열화시키거나 철근의 부식 등을 유발하여 콘크리트 구조물의 성능저하를 일으키게 된다.The concrete deterioration factors described above act alone or in combination to cause moisture or other external harmful substances to penetrate into the concrete, thereby deteriorating the concrete itself or causing corrosion of reinforcing bars, thereby deteriorating the performance of concrete structures.
이와 같은 콘크리트 구조물의 열화 및 균열이 심해되면 결국 구조물의 붕괴를 초래할 위험성이 있기 때문에 지속적으로 관리하고 보수할 필요가 있다.If the deterioration and cracks of such a concrete structure become severe, it is necessary to continuously manage and repair it because there is a risk of eventually causing the structure to collapse.
콘크리트 열화의 주요 원인이라고 할 수 있는 중성화는 콘크리트 내측으로 물이 침투하거나 공기 중의 탄산가스가 침투하여 콘크리트 내측에서 콘크리트 중의 수산화칼슘을 서서히 배출시킴으로써 C-S-H(칼슘 실리케이트 수화물) 결정체를 약화시킴에 따라 알칼리성이 상실되고 중성화가 진행된다. 콘크리트의 중성화가 진행되면 균열부위가 손상되면서 틈새가 넓어지고 이후 틈새 사이로 철근이 노출되면서 부식으로 진행되며, 일단 철근의 부식이 진행되면 녹에 의해 체적 팽창이 진행되어 그로 인한 팽창압이 콘크리트의 응력을 넘어 새로운 균열을 유발시키게 되며, 새로운 균열은 중성화를 더욱 가속화시켜 콘크리트 구조물의 내구성을 급속히 약화시키게 된다.Neutralization, which can be said to be the main cause of concrete deterioration, causes water to penetrate inside the concrete or carbon dioxide gas in the air to slowly discharge calcium hydroxide from the inside of the concrete, weakening the crystals of C-S-H (calcium silicate hydrate) and losing alkalinity. and neutralization proceeds. When concrete is neutralized, cracks are damaged and gaps widen, and then reinforcing bars are exposed through the gaps, leading to corrosion. Beyond this, new cracks are induced, and new cracks further accelerate neutralization, rapidly weakening the durability of concrete structures.
따라서 콘크리트 구조물의 균열이 발생하거나 균열 발생 가능성이 있으면 초기에 중성화가 급속히 진행하는 것을 방지하기 위해 보수 공사를 진행할 필요가 있다.Therefore, if cracks occur or there is a possibility of cracks in the concrete structure, it is necessary to carry out repair work to prevent the rapid progress of neutralization in the early stage.
한편, 아파트나 건물의 지붕 옥상 등 옥외 구조물은 외관을 미려하게 하기 위한 목적, 방수 목적 등으로 유색 또는 무색의 도료를 이용하여 외면을 도색하고 있다. 이러한 도료는 유성 또는 수성으로 이루어질 수 있으며, 최근에는 환경과 민원 방지를 위해 수성 도료가 많이 사용되고 있는데, 이러한 수성 도료의 경우 자외선에 의해 탈색되기 쉽고 시간이 지나면 경화되어 갈라지기 때문에 도료로서의 기능과 성능이 저하된다.On the other hand, outdoor structures such as roofs of apartments or buildings are painted with colored or colorless paints for the purpose of beautifying the exterior or waterproofing. These paints may be oil-based or water-based, and recently, water-based paints have been widely used to prevent environmental and civil complaints. In the case of these water-based paints, they are easily discolored by ultraviolet rays and harden and crack over time, so their functions and performance as paints this is lowered
이에 따라 현재 사용되는 수성 도료는 수명이 길지 않기 때문에 잦은 재도장이 필요한데, 도장 작업의 경우 인건비가 과다하므로 도장의 회수와 간격이 유지관리 비용을 결정하는 요인이 되고 있다. 따라서, 옥외 콘크리트 구조물에 도장된 도료의 내구성 및 내후성을 증대시켜 수명을 연장시킬 수 있는 콘크리트용 도료의 제공이 요구되고 있다.Accordingly, since the currently used water-based paint does not have a long lifespan, frequent re-coating is required. In the case of painting work, labor costs are excessive, so the number of times and intervals of painting are determining the maintenance cost. Therefore, there is a need to provide a paint for concrete that can extend the life of the paint by increasing the durability and weather resistance of the paint painted on the outdoor concrete structure.
본 발명의 목적은 콘크리트의 중성화를 방지하며, 방수성을 부여할 뿐만 아니라, 열과 자외선 차단효과가 우수하여 콘크리트의 수명을 향상시키는 도료 조성물을 제공하는 것이다.An object of the present invention is to provide a paint composition that prevents neutralization of concrete, imparts waterproofness, and improves the lifespan of concrete by having excellent heat and ultraviolet blocking effects.

상기 실리케이트계 혼합물은 50 내지 150 중량부가 혼합되며, 정제수 100 중량부, 실리케이트계 바인더 30 내지 250 중량부, 경화제 0.05 내지 1.5 중량부 및 pH조절제 0.05 내지 1.5 중량부로 이루어지는데, 상기 실리케이트계 바인더는 규산칼륨 100 중량부, 규산나트륨 20 내지 500 중량부 및 규산리튬 5 내지 100 중량부로 이루어지는 것이 바람직하다.The silicate-based mixture is mixed in 50 to 150 parts by weight, and is composed of 100 parts by weight of purified water, 30 to 250 parts by weight of a silicate-based binder, 0.05 to 1.5 parts by weight of a curing agent, and 0.05 to 1.5 parts by weight of a pH adjusting agent. The silicate-based binder is silicic acid. It is preferably composed of 100 parts by weight of potassium, 20 to 500 parts by weight of sodium silicate and 5 to 100 parts by weight of lithium silicate.
상기 실리케이트계 혼합물에 함유되는 실리케이트계 바인더는 11.5 내지 12.7 사이의 pH를 나타내며, 경화제는 규불산이 사용되어 1 내지 2의 pH를 나타내기 때문에, 상기와 같이 실리케이트계 바인더와 상기 경화제를 직접혼합하면 상호 화학반응에 의한 경화가 급속하게 진행되어 엉김현상이 발생하기 때문에 콘크리트의 표면에 도포할 수 없게 되므로, 상기 경화제 성분인 규불산을 상기의 함량으로 정제수 100 중량부에 혼합한 후에, 상기 실리케이트계 바인더를 혼합하는 것이 바람직하다.Since the silicate-based binder contained in the silicate-based mixture exhibits a pH between 11.5 and 12.7, and the curing agent exhibits a pH of 1 to 2 because silicic acid is used, when the silicate-based binder and the curing agent are directly mixed as described above, Curing by mutual chemical reaction proceeds rapidly and coagulation occurs, so that it cannot be applied to the surface of concrete. Mixing the binder is preferred.
상기 실리케이트계 바인더는 상기 경화제와 혼합되어 실리케이트계 혼합물의 최종 pH를 12 내지 12.5로 조절하는 역할을 하며, pH가 12 내지 12.5 조절된 실리케이트계 혼합물이 함유된 도료 조성물은 콘크리트의 벽면에서는 곰팡이나 녹조류의 세포질 원형질막이 파괴되고, 효소와 막수송단백질의 활성이 억제되어 곰팡이나 녹조류 등의 증식이 차단된다.The silicate-based binder is mixed with the curing agent to serve to adjust the final pH of the silicate-based mixture to 12 to 12.5, and the paint composition containing the silicate-based mixture whose pH is adjusted to 12 to 12.5 prevents mold or green algae on the wall of concrete. The cytoplasmic plasma membrane of the cell is destroyed, and the activity of enzymes and membrane transport proteins is inhibited, preventing the proliferation of fungi and green algae.
또한, 상기와 같은 곰팡이나 녹조류 등과 같은 미생물이 자라기 위해서는 영양원, 온도, pH 및 습도 등의 조건들이 맞아하는데, 영양원은 미생물이 성장하기 위해 필요하며 필수영양소(탄소, 질소, 인, 황 등)가 부족하다면 기타의 영양소의 농도와 관계없이 곰팡이 및 녹조 등의 미생물은 생장이 억제된다.In addition, in order for microorganisms such as molds and green algae as described above to grow, conditions such as nutrient sources, temperature, pH, and humidity are met. Nutrient sources are necessary for microorganisms to grow and essential nutrients (carbon, nitrogen, phosphorus, sulfur, etc.) If insufficient, the growth of microorganisms such as mold and algae is inhibited regardless of the concentration of other nutrients.
또한, 상기 실리케이트계 혼합물에 함유된 실리케이트계 바인더는 콘크리트가 대기중의 탄산가스와 접촉하여 탄산칼슘과 물로 전환되면서, 열화되는 것을 차단하는데, 상기 실리케이트계 바인더의 성분인 규산칼륨(K2SiO2), 규산나트륨(Na2SiO2) 및 규산리튬(Li2O-nSiO2-xH2O)에 존재하는 +1가의 칼륨, 나트륨 및 리튬이 이온결합을 통해 CO3를 치환하며, 중성화가 진행된 콘크리트의 pH를 11 내지 12로 향상시켜 강알칼리화 시키고, 이온결합을 통해 콘크리트 내부의 유리된 시멘트 성분과 가교결합을 함으로써 콘크리트의 표면과 내부의 기계적 강도를 증가시키는 역할을 한다.In addition, the silicate-based binder contained in the silicate-based mixture prevents concrete from deteriorating while being converted to calcium carbonate and water in contact with carbon dioxide gas in the air, potassium silicate (K 2 SiO 2 ), sodium silicate (Na 2 SiO 2 ) and lithium silicate (Li 2 O-nSiO 2 -xH 2 O), the +1 valent potassium, sodium, and lithium replace CO 3 through ionic bonds, and neutralization proceeds. It serves to increase the mechanical strength of the surface and inside of the concrete by improving the pH of the concrete to 11 to 12 to make it strong alkalinity and cross-linking with the free cement component inside the concrete through ionic bonding.
이때, 상기 규산리튬은 10 내지 20 나노미터의 입자크기를 갖는 것이 바람직한데, 10 내지 20 나노미터의 입자크기를 갖는 규산리튬은 콘크리트 내부에 형성된 공극을 메워줌으로, 콘크리트 내부의 함수율과 산소함유량을 낮춰 호기성 곰팡이 및 녹조류류 등이 증식하는 것을 차단할 수 있다.At this time, the lithium silicate preferably has a particle size of 10 to 20 nanometers, and the lithium silicate having a particle size of 10 to 20 nanometers fills the voids formed inside the concrete, thereby increasing the moisture content and oxygen content in the concrete. It can block the proliferation of aerobic mold and green algae by lowering the
또한, 상기 경화제는 상기 실리케이트계 바인더의 경화를 촉진하는 역할을 한다. 또한, 상기 경화제는 콘크리트 벽면에 도료 조성물이 도포된 후에 경화를 촉진하는데, 상기 실리케이트계 바인더와 CO3의 이온결합을 촉진하는 역할을 하고, 실리케이트계 혼합물이 콘크리트에 도포된 후에 상기 정제수가 증발되면, 경화제의 상대적인 농도가 증가하여 전술한 실리케이트계 바인더와 급속한 경화반응이 진행되기 때문에 콘크리트와의 우수한 결합력을 갖도록 하는 역할을 한다.In addition, the curing agent serves to promote curing of the silicate-based binder. In addition, the curing agent promotes curing after the coating composition is applied to the concrete wall surface, serves to promote ionic bonding between the silicate-based binder and CO 3 , and when the purified water evaporates after the silicate-based mixture is applied to the concrete , since the relative concentration of the curing agent increases and the rapid curing reaction with the above-mentioned silicate-based binder proceeds, it serves to have excellent bonding strength with concrete.
또한, 상기 pH조절제는 수산화나트륨으로 이루어지는데, 본 발명에 따른 실리케이트계 혼합물의 pH를 12 내지 12.5로 조절하는 역할을 한다.In addition, the pH adjusting agent is composed of sodium hydroxide, and serves to adjust the pH of the silicate-based mixture according to the present invention to 12 to 12.5.
상기 pH조절제의 함량이 0.05 중량부 미만이면 실리케이트계 혼합물의 pH가 낮아져 곰팡이 및 세균의 증식을 차단할 수 없으며, 상기 pH조절제의 함량이 1.5 중량부 이상을 초과하게 되면 상기의 효과는 크게 향상되지 않으면서 도료 조성물의 물성이 지나치게 저하될 수 있다.If the content of the pH adjusting agent is less than 0.05 parts by weight, the pH of the silicate-based mixture is lowered and the growth of mold and bacteria cannot be blocked, and if the content of the pH adjusting agent exceeds 1.5 parts by weight or more, the effect is not greatly improved. Therefore, the physical properties of the paint composition may be excessively deteriorated.
상기 실리케이트계 혼합물의 함량이 50 중량부 미만이면 상기의 효과가 미미하며, 상기 실리케이트계 혼합물의 함량이 150 중량부를 초과하게 되면 상기의 효과는 크게 향상되지 않으면서 상대적으로 실리콘 아크릴 에멀젼, 불소변성수지 및 충전재의 함량이 지나치게 줄어들어 중성화 방지, 방수성 부여 및 자외선 차단 등의 효과가 저하될 수 있다.When the content of the silicate-based mixture is less than 50 parts by weight, the above effect is insignificant, and when the content of the silicate-based mixture exceeds 150 parts by weight, the above effects are not greatly improved, and relatively silicone acrylic emulsions and fluoromodified resins And since the content of the filler is excessively reduced, effects such as preventing neutralization, imparting waterproofness, and blocking ultraviolet rays may be deteriorated.
이하에서는, 본 발명에 따른 차열 및 방수기능을 통한 콘크리트의 수명향상 효과를 나타내는 도료 조성물의 제조방법 및 그 제조방법으로 제조된 도료 조성물의 물성을 실시예를 들어 설명하기로 한다.Hereinafter, the manufacturing method of the coating composition exhibiting the effect of improving the lifespan of concrete through the heat shielding and waterproofing function according to the present invention and the physical properties of the coating composition prepared by the manufacturing method will be described by way of examples.
