Abstract
본 발명은 내열성, 내자외선 특성 및 항균성이 우수한 실리콘 실란트 및 그의 제조 방법에 관한 것으로서, 더욱 상세하게는 각종 건축용 자재나 내외장재에 실링제로 사용되는 실란트에 있어서 내열성을 강화할 수 있는 성분을 추가함으로써 내열성 및 방화특성을 향상시킬 수 있으며, 일정 시간이 경화하여도 표면과 접착 부위에서 자외선이나 그 외 외부 환경에 대해 내구성이 저하되지 않아 실란트로서의 기능이 상실되지 않는 동시에, 접착 부위를 중심으로 곰팡이나 미생물이 번식하여 오염되는 문제를 개선할 수 있는 실리콘 실란트 및 그 제조 방법에 관한 것이다. The present invention relates to a silicone sealant with excellent heat resistance, UV resistance, and antibacterial properties and a method of manufacturing the same. More specifically, it relates to a silicone sealant used as a sealant for various building materials or interior and exterior materials, and to a silicone sealant that can enhance heat resistance by adding ingredients that can enhance heat resistance. Fire prevention characteristics can be improved, and even after curing for a certain period of time, the durability of the surface and adhesive area against ultraviolet rays or other external environments is not reduced, so the function as a sealant is not lost. At the same time, fungi and microorganisms are prevented from forming around the adhesive area.

It relates to a silicone sealant that can improve the problem of propagation and contamination and a method of manufacturing the same.
각종 건축용 자재나 내외장재의 경우 조인트부나 갈라진 틈에 대한 기밀 및 수밀을 유지하기 위하여 실링제를 사용한다. 이러한 실링제는 어느 정도 강도 및 탄성을 가지고 있어서 건축용 자재나 내외장재 등의 부재를 고정시켜 건축물의 내구성을 강화하는 목적으로 사용된다. In the case of various building materials or interior and exterior materials, sealing agents are used to maintain airtightness and watertightness in joints and cracks. These sealing agents have a certain degree of strength and elasticity, so they are used to strengthen the durability of buildings by fixing members such as building materials or interior and exterior materials.
이러한 실링제 중에서 탄성을 가진 실링제를 보통 실란트(sealant)라고 하는데, 이러한 실란트는 방수성, 작업성, 부착성 등의 물성이 우수해야 하고, 완전 경화시에는 조인트부가 움직여도 파열되거나 박리되지 않는 강도 및 탄성을 가질 필요가 있으며, 옥외 조건에서도 내후성, 내한성, 내열성, 내수성 등의 물성이 우수해야 한다. Among these sealants, those with elasticity are usually called sealants. These sealants must have excellent physical properties such as waterproofing, workability, and adhesion, and when fully cured, they must have the strength to not rupture or peel even when the joint moves. It needs to have elasticity and must have excellent physical properties such as weather resistance, cold resistance, heat resistance, and water resistance even under outdoor conditions.
기존의 실란트, 그 중에서도 실리콘 수지로 이루어진 실리콘 실란트는 시공 후 일정한 시간이 지나면 접착 부위를 중심으로 자외선이나 그외 외부 환경에 의해 내구성이 약해져서 실란트의 접착력이 저하되고 노화가 일어나서 수명이 짧아지는 문제가 있었다. Existing sealants, especially silicone sealants made of silicone resin, had a problem in that after a certain period of time after construction, the durability of the sealant weakened due to ultraviolet rays or other external environments around the adhesive area, causing the adhesive strength of the sealant to deteriorate and aging to occur, shortening the lifespan. .
또한, 외부에 노출되면 급격한 접착력 약화와 함께 산화가 일어나서 수명이 다하는 문제가 있었다. In addition, when exposed to the outside, there was a problem of rapid weakening of adhesion and oxidation, which led to the end of its lifespan.
또한, 기존의 실리콘 실란트는 화재 발생시 화재 전달의 매개체가 되지 않는 것이 중요한데, 기존의 실리콘 실란트는 내열성 및 난연성이 부족하여 건축용 자재 또는 내외장재로의 화재 전달의 매개체가 되는 문제가 있어서 이에 대한 개선의 필요성이 있었다. In addition, it is important that existing silicone sealants do not become a medium for fire transmission in the event of a fire. However, existing silicone sealants lack heat resistance and flame retardancy, so there is a problem of becoming a medium for fire transmission to building materials or interior and exterior materials, so there is a need for improvement. There was this.
또한, 기존의 실리콘 실란트는 시공 후 일정 시간이 지나면 미생물이나 곰팡이가 번식하여 오염이 쉽게 되는 문제가 있었으며, 한번 오염되면 쉽게 제거되기 어려운 문제도 있어서, 이에 대한 개선의 필요성도 있었다. In addition, the existing silicone sealant had the problem of being easily contaminated by microorganisms or mold growth after a certain period of time after construction, and once contamination was difficult to remove, there was a need for improvement.

이하, 본 발명에 관하여 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail.
본 발명에 따른 건축용 실리콘 실란트는 폴리디메틸실록산 30~60 중량부, 실리콘 다이옥사이드 5~20 중량부, 실란 가교제 0.5~5.0 중량부, 나노실버 미립 분말 0.02~2.0 중량부, 팽창흑연 0.1~5.0 중량부, 에어로겔 함유액 0.01~0.5 중량부, 자외선 흡수제 0.01~1.0 중량부, 산화방지제 0.01~1.0 중량부 및 반응촉매 0.01~1.0 중량부를 포함하여 구성된다. The architectural silicone sealant according to the present invention contains 30 to 60 parts by weight of polydimethylsiloxane, 5 to 20 parts by weight of silicon dioxide, 0.5 to 5.0 parts by weight of silane crosslinker, 0.02 to 2.0 parts by weight of nanosilver fine powder, and 0.1 to 5.0 parts by weight of expanded graphite. , 0.01 to 0.5 parts by weight of airgel-containing liquid, 0.01 to 1.0 parts by weight of ultraviolet absorber, 0.01 to 1.0 parts by weight of antioxidant, and 0.01 to 1.0 parts by weight of reaction catalyst.
본 발명에서 상기 폴리디메틸실록산은 실란트의 기계적 물성을 유지하고 탄성을 유지하는 역할을 한다. 본 발명에서 상기 폴리디메틸실록산은 중량평균분자량이 20,000~100,000 g/mol이고 비닐기 함량이 약 0.1~5 몰%, 경도는 0.2~200 Pas인 것을 사용하는 것이 바람직하다. 비닐기의 함량이 0.1 몰% 미만이면 기계적 물성의 유지가 어렵고, 5 몰%를 넘으면 반발탄성이 커서 성형이 어려울 수 있다. 본 발명에서 상기 폴리디메틸실록산은 전체 실리콘 실란트 성분 중에 30~60 중량부의 범위로 포함되는 것이 물성 및 탄성 유지를 위하여 바람직하다. In the present invention, the polydimethylsiloxane serves to maintain the mechanical properties and elasticity of the sealant. In the present invention, the polydimethylsiloxane is preferably used with a weight average molecular weight of 20,000 to 100,000 g/mol, a vinyl group content of about 0.1 to 5 mol%, and a hardness of 0.2 to 200 Pas. If the vinyl group content is less than 0.1 mol%, it is difficult to maintain mechanical properties, and if it exceeds 5 mol%, the rebound elasticity is large and molding may be difficult. In the present invention, the polydimethylsiloxane is preferably included in the range of 30 to 60 parts by weight in the total silicone sealant components to maintain physical properties and elasticity.
본 발명에서 상기 실리콘 다이옥사이드는 경도 등 기계적 물성을 강화하는 역할을 하는 것으로서, 그 함량은 전체 실리콘 실란트 성분 중에 5~20 중량부의 범위로 포함되는 것이 기계적 강도 유지를 위하여 바람직하다. In the present invention, the silicon dioxide plays a role in strengthening mechanical properties such as hardness, and its content is preferably in the range of 5 to 20 parts by weight in the total silicone sealant components to maintain mechanical strength.
본 발명에서 상기 실란 가교제는 주재인 폴리디메틸실록산 및 실리콘 다이옥사이드의 가교제 기능을 하는 것으로서, 메틸옥시미노실란 또는 비놀옥시미노실란 중에서 선택된 1종 또는 2종을 사용할 수 있다. 본 발명에서 상기 실란 가교제의 함량은 전체 실리콘 실란트 성분 중에 0.5~5.0 중량부의 범위로 포함되는 것이 바람직하다. 상기 실란 가교제가 0.5 중량부 미만이면 미반응 잔량이 존재하므로 가교로 인한 연질 구조가 형성되는 문제가 있어 실란트로서의 요구 강도보다 취약해질 수 있다는 문제가 있고, 5.0 중량부를 넘으면 과잉의 반응기가 존재하여 대기 중의 수분과 반응을 할 수 있으므로 저장 안정성이 취약해질 수있다는 문제가 있다. In the present invention, the silane crosslinking agent functions as a crosslinking agent for the main components polydimethylsiloxane and silicon dioxide, and one or two types selected from methyloxyminosilane or binoloxyminosilane may be used. In the present invention, the content of the silane crosslinking agent is preferably included in the range of 0.5 to 5.0 parts by weight based on the total silicone sealant components. If the amount of the silane crosslinking agent is less than 0.5 parts by weight, there is an unreacted residual amount, so there is a problem of forming a soft structure due to crosslinking, which may make it weaker than the required strength as a sealant. If it exceeds 5.0 parts by weight, there is an excess of reactors, causing atmospheric pressure. There is a problem that storage stability may become weak because it may react with moisture in the product.
본 발명에서 상기 나노실버 미립 분말은 희석제에 희석하여 포함시키는 것이 바람직하며, 나노실버 미립 분말의 평균 직경은 5~50 nm의 범위에 드는 것을 사용하는 것이 바람직하다. 상기 직경이 5 nm 미만이면 경제성이 떨어지며, 50 nm를 초과하면 실란트에 사용시 항균력을 발휘하기 어렵다는 문제가 있다. 또한, 본 발명에서 상기 나노실버 미립 분말의 표면적은 50~400m2/g인 것을 사용하는 것이 바람직하다. 또한, 상기 나노실버 미립 분말의 함량은 전체 실리콘 실란트 성분 중에 0.05~2.0 중량부의 범위로 포함되는 것이 항균력 발휘 및 경제성을 위하여 바람직하다. In the present invention, the nanosilver fine powder is preferably diluted in a diluent and included, and the average diameter of the nanosilver fine powder is preferably in the range of 5 to 50 nm. If the diameter is less than 5 nm, economic efficiency is low, and if it exceeds 50 nm, there is a problem in that it is difficult to exert antibacterial activity when used as a sealant. Additionally, in the present invention, it is preferable to use the nanosilver fine powder having a surface area of 50 to 400 m 2 /g. In addition, the content of the nanosilver fine powder is preferably included in the range of 0.05 to 2.0 parts by weight in the total silicone sealant components for the sake of antibacterial activity and economic efficiency.
본 발명에서 상기 팽창흑연은 실란트에 난연성 및 내열성을 부여하기 위해 사용되는 것으로서, 탄소함량이 70~99%이고, 팽창율이 50~500ml/g인 것을 사용하는 것이 바람직하다. 상기 팽창흑연은 탄소함량이 적정할 때 난연성을 발휘하는데, 상기 범위의 탄소함량을 갖는 것을 사용하는 것이 바람직하다. In the present invention, the expanded graphite is used to provide flame retardancy and heat resistance to the sealant, and is preferably used with a carbon content of 70 to 99% and an expansion rate of 50 to 500 ml/g. The expanded graphite exhibits flame retardancy when the carbon content is appropriate, and it is preferable to use one having a carbon content in the above range.
상기 팽창흑연은 내열성, 내구성, 윤활성, 가소성, 화학적 안정성, 방열성 등의 특성이 발휘되도록 하는 성분으로서, 특히 할로겐 프리의 난연제로 연기 발생을 억제하고 팽창된 탄소층이 절연층으로 작용하여 열의 이동을 방해하고 비할로겐 타입의 저발연성 친환경 난연제로 적용될 수 있어, 실란트에 난연성과 더불어 우수한 물성을 발휘하게 하는 역할을 한다. The expanded graphite is a component that exhibits properties such as heat resistance, durability, lubricity, plasticity, chemical stability, and heat dissipation. In particular, it is a halogen-free flame retardant that suppresses smoke generation and the expanded carbon layer acts as an insulating layer to prevent heat transfer. It can be applied as a low-smoke, non-halogen-type, eco-friendly flame retardant that helps sealants exhibit excellent physical properties as well as flame retardancy.
본 발명에서 상기 팽창흑연의 함량은 전체 실리콘 실란트 성분 중에 0.1~5.0 중량부의 범위로 포함되는 것이 바람직한데, 팽창흑연이 0.1 중량부 미만이면 난연성, 내열성, 물성 향상 등의 효과를 보기 어렵고, 5.0 중량부를 초과하면 분산성이 떨어져서 오히려 물성이 악화될 수 있는 문제가 있으므로 상기 범위 내로 사용되는 것이 바람직하다. In the present invention, the content of the expanded graphite is preferably included in the range of 0.1 to 5.0 parts by weight in the total silicone sealant components. If the expanded graphite is less than 0.1 parts by weight, it is difficult to see effects such as improving flame retardancy, heat resistance, and physical properties, and 5.0 parts by weight If the amount is exceeded, the dispersibility may decrease and the physical properties may deteriorate, so it is preferable to use it within the above range.
본 발명에서 상기 에어로겔 함유액은 에어로겔 10 ~20 중량부, 흄드실리카 1~5 중량부, 유기바인더 1~5 중량부, 유기용매 10~40 중량부, 유무기 복합충진재 1~10 중량부, 수용성 바인더 1~5 중량부, 난연성 첨가제 0.1~5 중량부 및 증류수 20~50 중량부의 비율로 혼합하여 얻어진 것을 사용할 수 있다. In the present invention, the airgel-containing solution is 10 to 20 parts by weight of airgel, 1 to 5 parts by weight of fumed silica, 1 to 5 parts by weight of organic binder, 10 to 40 parts by weight of organic solvent, 1 to 10 parts by weight of organic-inorganic composite filler, It can be used by mixing 1 to 5 parts by weight of a water-soluble binder, 0.1 to 5 parts by weight of a flame retardant additive, and 20 to 50 parts by weight of distilled water.
본 발명에서 상기 에어로겔은 90 ~ 99.8%가 공기로 이루어져 있고, 보통 밀도는 3 ~ 150 ㎎/㎤이며, 스티로폼과 같은 느낌이 나지만 말랑말랑하지는 않고 한 번 눌리면 복원되지 않는 특성을 갖는다. 또한, 강한 압력을 가하면 유리와 같이 산산조각으로 깨지는 특성이 있지만, 구조적으로는 매우 튼튼하여 자기 무게의 2000배 정도로 지탱할 수 있는데, 이는 2 ~ 5 nm 크기의 구형 파티클(particle)들이 결합되어 나뭇가지 형태의 클러스터(cluster)를 형성하는 미세구조에 기인한다. 이런 클러스터는 3차원적인 그물망 모양으로 100nm보다 작은 기공을 가진 다공성 구조를 형성하며, 기공의 평균 크기와 밀도는 조절될 수 있다.In the present invention, the airgel is composed of 90 to 99.8% air, has a normal density of 3 to 150 mg/cm3, and has a feeling like Styrofoam, but is not soft and does not recover once pressed. In addition, when strong pressure is applied, it has the property of breaking into pieces like glass, but it is structurally very strong and can support about 2,000 times its own weight, which is formed by combining spherical particles of 2 to 5 nm in size to form a tree branch. It is due to the microstructure that forms a cluster. These clusters form a three-dimensional mesh-like porous structure with pores smaller than 100 nm, and the average size and density of the pores can be controlled.
상기 에어로젤은 현저한 단열 및 내화성능을 보이는데, 이는 열전달이 일어나는 3가지 방법인 대류, 전도, 복사를 무력화시키기 때문이다. 대류를 효과적으로 차단하는 이유는 공기가 기공을 통해 순환할 수 없기 때문이다.The airgel exhibits remarkable thermal insulation and fire resistance properties because it neutralizes the three methods of heat transfer: convection, conduction, and radiation. The reason it effectively blocks convection is because air cannot circulate through the pores.
본 발명에서 상기 에어로겔은 실리카, 알루미나, 티타니아, 탄소 에어로겔 중에서 선택된 1종 이상을 사용할 수 있으며, 더욱 바람직하게는 실리카 에어로겔을 사용할 수 있다. In the present invention, the airgel may be one or more selected from silica, alumina, titania, and carbon airgel, and more preferably, silica airgel may be used.
본 발명에서 상기 건축용 실리콘 실란트에 에어로젤을 미량 첨가함으로써 내부에 기공이 형성되어 단열성과 내화성을 향상시킬 수 있으며, 표면 전체에 걸쳐 형성된 에어로젤의 소수성에 따른 발수성능으로 실리콘 실란트의 내수성도 향상시킬 수 있다. In the present invention, by adding a small amount of airgel to the architectural silicone sealant, pores are formed inside to improve insulation and fire resistance, and the water resistance of the silicone sealant can be improved due to the water-repellent performance due to the hydrophobicity of the airgel formed over the entire surface. .
본 발명에서 상기 흄드실리카는 에어로겔 함유액에 포함되어 에어로겔 입자 사이의 간극에 채워지면서 단열성을 증대시키는 역할을 한다. In the present invention, the fumed silica is included in the airgel-containing liquid and fills the gaps between airgel particles to increase thermal insulation.
본 발명에서 상기 유기바인더는 에어로겔의 접착력 향상을 위해 사용되며, 유기바인더의 예로는 에폭시수지, 우레탄수지, 폴리비닐부티랄수지, 폴리이미드수지 등을 사용할 수 있다. In the present invention, the organic binder is used to improve the adhesion of airgel, and examples of the organic binder include epoxy resin, urethane resin, polyvinyl butyral resin, and polyimide resin.
본 발명에서 상기 유기용매는 에어로겔을 겔화시켜 균일하게 분산되도록 하는 물질로서 에어로겔의 기공 내부로 충진되면서 에어로겔의 기공 내부로 물이 침투되지 않도록 하고 건조과정에서 에어로겔의 기공 내부에 충진된 유기용매가 휘발되면서 에어로겔의 기공을 확보하여 단열성을 증진시키도록 하는 역할을 한다. 본 발명에서 상기 상기 유기용매의 예로는 메틸사이클로헥사놀, 아이소부탄올, 노말헥산 등을 사용할 수 있다. In the present invention, the organic solvent is a substance that gels the airgel and disperses it evenly. It fills the pores of the airgel, prevents water from penetrating into the pores of the airgel, and volatilizes the organic solvent filled in the pores of the airgel during the drying process. It plays a role in securing the pores of the airgel and improving its insulation properties. Examples of the organic solvent in the present invention include methylcyclohexanol, isobutanol, and normal hexane.

Characterized in that it is used by mixing ~5 parts by weight, 0.1~5 parts by weight of flame retardant additive, and 20~50 parts by weight of distilled water,
The organic binder is selected from epoxy resin, urethane resin, polyvinyl butyral resin, and polyimide resin,
The organic solvent is selected from methylcyclohexanol, isobutanol, and normal hexane,
The organic-inorganic composite filler is a composite filler that includes inorganic particles surface-treated with a silane coupling agent having a double bond and an organic filler in the core,
The organic filler is polytetrafluoroethylene powder or polyfluorobinylidene powder,
The silane coupling agent having the double bond is vinyltrimethoxysilane, vinyltriethoxysilane, p-styryl trimethoxysilane, or 3-methacryloxypropyl trimethoxysilane,
The inorganic particles include alumina, magnesium oxide, calcium sulfate, carbon powder, vermiculite, perlite, or kaolin,
The water-soluble binder functions to prevent the airgel particles from detaching while attaching the fumed silica and the organic-inorganic composite filler between the airgel particles, and can be selected from among cellulose resin, acrylic resin, urethane resin, polyethylene resin, or polyacetal resin. Use the selected one,
The flame retardant additive functions to enhance the flame retardancy, heat resistance, and fire resistance of the entire silicon sealant through a synergistic effect with the expanded graphite, and is a method of manufacturing a silicone sealant for construction, characterized in that it uses molybdenum oxide.
