내외장용 건축자재로서, 흡음, 단열, 내화, 결로방지 등의 목적으로 가장 널리 사용되는 내·외장재용의 구성원료는 유리면, 암면, 세라믹 파이버, 셀룰로오스 등의 섬유상 물질과 목분을 이용한 합성목재, 기타 복합건축자재 등 그 종류가 매우 다양하며, 조립식 건축자재로 사용되는 패널로는 EPS, 우레탄, MDF, 그라스울, 콘크리트 PC, ALC 패널 등이 있다. 그러나 상기와 같은 건축자재의 내·외장재는 각각 환경오염, 화재에 대한 취약성, 연소에 의한 유독가스 발생 등의 문제점이 있는바, 이를 해소하기 위한 여러 소재가 개발되고 있다. As interior and exterior building materials, the most widely used interior and exterior building materials for the purposes of sound absorption, insulation, fire resistance, and condensation prevention are fibrous materials such as glass wool, rock wool, ceramic fiber, and cellulose, synthetic wood using wood flour, and others. There are many different types of composite building materials, and panels used as prefabricated building materials include EPS, urethane, MDF, glass wool, concrete PC, and ALC panels. However, the interior and exterior construction materials mentioned above each have problems such as environmental pollution, vulnerability to fire, and generation of toxic gases due to combustion, and various materials are being developed to solve these problems.
한편, 각종 접합부나 갈라진 틈에 대한 수밀, 기밀을 유지하기 위하여 충진되는 물질을 일반적으로 실링재라고 말하며, 이는 어느 정도 강도 및 탄성을 가지고 부재를 고정시켜 건축물의 내구성을 증진시키는 목적으로 사용된다. 그리고 실링재 중 특히 탄성 실링재를 실란트라고 한다.Meanwhile, materials filled to maintain watertightness and airtightness of various joints or cracks are generally referred to as sealing materials, and are used to improve the durability of buildings by fixing members with a certain degree of strength and elasticity. And among sealing materials, especially elastic sealing materials are called sealants.
이러한 실란트는 수밀, 기밀의 기능적인 목적만을 추구하였는바, 최근 이러한 실란트 역시 방화성능이 요구되며, 실링에 의한 유독가스 및 열기에 대한 확실한 차단 효과가 요구되고 있는 실정이다.These sealants have pursued only the functional purpose of watertightness and airtightness, but recently, these sealants are also required to have fire prevention performance and are required to have a reliable blocking effect against toxic gases and heat caused by sealing.

이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명의 내화 및 내열 알콕시 실리콘 실란트 조성물은, 내화 및 내열 첨가제로 산화철, 수산화알루미늄, 실리카 에어로겔 분말, 나노 그래핀 플레이크 등을 투입하여 실란트 조성물을 제조함으로써, 우수한 접착성 및 기밀성을 가지면서도 내화성이 향상되어, 방화성능이 요구되는 각종 건축 구조물, 복층유리 등에 실링재로서 사용될 수 있다는 데 가장 큰 특징이 있다.The fire-resistant and heat-resistant alkoxy silicone sealant composition of the present invention is manufactured by adding iron oxide, aluminum hydroxide, silica airgel powder, nano graphene flake, etc. as fire-resistant and heat-resistant additives, thereby having excellent adhesion and airtightness while being fire resistant. The biggest feature is that it can be used as a sealing material in various building structures and double-layer glass that require improved fire prevention performance.
구체적으로 본 발명에 의한 내화 및 내열 알콕시 실리콘 실란트 조성물은, 하이드로 터미네이트된 폴리실록산(Siloxanes and Silicones, di-Me, hydroxy-terminated) 100중량부, 디메틸폴리실록산(Dimethyl silicones and siloxanes) 20~70중량부, 실란 경화제 5~35중량부, 무기 충전제 50~100중량부, 가교제 2~20중량부, 산화철 10~30중량부, 수산화알루미늄 50~100중량부, 실리카 에어로겔 분말 10~20중량부 및 나노 그래핀 플레이크 10~20중량부를 포함하는 것을 특징으로 한다.Specifically, the fire-resistant and heat-resistant alkoxy silicone sealant composition according to the present invention contains 100 parts by weight of hydroterminated polysiloxane (Siloxanes and Silicones, di-Me, hydroxy-terminated) and 20 to 70 parts by weight of dimethylpolysiloxane (Dimethyl silicones and siloxanes). , 5 to 35 parts by weight of silane curing agent, 50 to 100 parts by weight of inorganic filler, 2 to 20 parts by weight of crosslinker, 10 to 30 parts by weight of iron oxide, 50 to 100 parts by weight of aluminum hydroxide, 10 to 20 parts by weight of silica airgel powder, and nanograph. It is characterized in that it contains 10 to 20 parts by weight of pin flakes.
먼저, 상기 하이드로 터미네이트된 폴리실록산(Siloxanes and Silicones, di-Me, hydroxy-terminated, cas no. 70131-67-8)과 디메틸폴리실록산(Dimethyl silicones and siloxanes, cas no. 63148-62-9)은 실란트 조성물을 구성하는 주재료로서, 이 기술이 속하는 분야에서 이미 공지된 성분이다. 이하, 조성물 내 '중량부'는 하이드로 터미네이트된 폴리실록산 100중량부를 기준으로 한다.First, the hydro-terminated polysiloxane (Siloxanes and Silicones, di-Me, hydroxy-terminated, cas no. 70131-67-8) and dimethylpolysiloxane (Dimethyl silicones and siloxanes, cas no. 63148-62-9) are sealants. As the main material constituting the composition, it is a component already known in the field to which this technology belongs. Hereinafter, 'parts by weight' in the composition is based on 100 parts by weight of hydroterminated polysiloxane.
상기 디메틸폴리실록산은 실란트 조성물의 물성을 고려하여, 조성물 내 20~70중량부로 포함된다. Considering the physical properties of the sealant composition, the dimethylpolysiloxane is included in an amount of 20 to 70 parts by weight in the composition.
상기 실란 경화제는 실란트 조성물의 경화를 위한 것으로, 예컨데 트리메톡시비닐실란(Trimethoxyvinylsilane, cas no. 2768-02-07) 및 트리메톡시메틸실란(Trimethoxymethylsilane, cas no. 1185-55-3)를 1종 또는 2종을 조합하여 사용할 수 있다.The silane curing agent is for curing the sealant composition, for example, trimethoxyvinylsilane (cas no. 2768-02-07) and trimethoxymethylsilane (cas no. 1185-55-3). One type or two types can be used in combination.
상기 실란 경화제는 실란트 조성물의 물성을 고려하여, 조성물 내 5~35중량부로 포함된다. The silane curing agent is included in 5 to 35 parts by weight in the composition, considering the physical properties of the sealant composition.
상기 무기 충전제는 실란트의 강도, 경도 등을 적절하게 조절해주는 물질로서, 칼슘 카보네이트(Calcium carbonate)를 사용함이 바람직하다. 상기 칼슘 카보네이트는 실란트 조성물의 내화 특성을 개선하면서도, 결합력을 높여주는 역할을 한다. The inorganic filler is a material that appropriately adjusts the strength and hardness of the sealant, and calcium carbonate is preferably used. The calcium carbonate plays a role in improving the fire resistance properties of the sealant composition and increasing bonding strength.
상기 무기 충전제는 조성물 내 50~100중량부로 포함됨이 바람직한데, 그 함량이 너무 적으면 물성의 향상 효과가 미미하고, 과량이 되면 전체적인 접착력이 저하되는 등의 문제가 있기 때문이다. The inorganic filler is preferably included in the composition in an amount of 50 to 100 parts by weight. If the content is too small, the effect of improving the physical properties is minimal, and if the content is excessive, there is a problem such as a decrease in overall adhesion.
상기 가교제는 폴리머의 가교 반응을 위한 것으로, 이 기술이 속하는 분야에서 공지된 것이라면 모두 사용 가능하며, 예시적으로 Bis(ethyl 3-oxobutanoatoO1',O3)bis(2-propanolato)titanium(cas no. 27858-32-8)를 사용할 수 있다.The cross-linking agent is for the cross-linking reaction of polymers, and any agent known in the art can be used, for example Bis(ethyl 3-oxobutanoatoO1',O3)bis(2-propanolato)titanium (cas no. 27858) -32-8) can be used.
상기 가교제는 조성물 내 2~20중량부로 포함될 수 있는바, 그 함량이 너무 적거나 많으면 실란트 조성물의 물성이 저하되기 때문이다.The crosslinking agent may be included in an amount of 2 to 20 parts by weight in the composition, because if the content is too small or too large, the physical properties of the sealant composition deteriorate.
상기 산화철은 내열 첨가제로서, 조성물의 내열성을 현저히 개선해주는 역할을 한다. 상기 산화철로는 산화철(Ⅱ), 산화철(Ⅲ), 사산화삼철로 이루어진 군으로부터 선택된 하나 이상을 사용할 수 있으며, 그 종류를 제한하지 않는다. 본 발명에서 상기 산화철의 입도는 0.1~500㎛인 것이 바람직하다.The iron oxide is a heat resistance additive and serves to significantly improve the heat resistance of the composition. The iron oxide may be one or more selected from the group consisting of iron (II) oxide, iron (III) oxide, and triferon tetroxide, and the type is not limited. In the present invention, the particle size of the iron oxide is preferably 0.1 to 500 μm.
상기 산화철은 조성물 내 10~30중량부로 포함됨이 바람직한데, 그 함량이 너무 적으면 내열성의 향상이 어렵고, 과량이 되면 전체적인 물성이 저하되기 때문이다. The iron oxide is preferably included in the composition in an amount of 10 to 30 parts by weight. If the content is too small, it is difficult to improve heat resistance, and if the content is excessive, the overall physical properties deteriorate.
상기 수산화알루미늄(aluminium trihyroxide)은 열에 의해 분해될 때 수증기를 배출하여 일부 연소 가스를 희석하고, 열을 흡수하는 성질을 포함하고 있어 연소의 확산을 방지하는 역할을 하기 때문에 내화 첨가제로서 사용된다. Aluminum hydroxide (aluminum trihyroxide) releases water vapor when decomposed by heat, diluting some combustion gases, and has the property of absorbing heat, thereby preventing the spread of combustion, so it is used as a fire-retardant additive.
상기 수산화알루미늄은 조성물 내 50~100중량부로 포함됨이 바람직한데, 그 함량이 상기한 범위를 벗어날 경우 충분한 내화성의 확보가 어렵거나, 실란트 조성물의 물성을 저해하기 때문이다.The aluminum hydroxide is preferably included in the composition in an amount of 50 to 100 parts by weight, because if the content exceeds the above range, it is difficult to secure sufficient fire resistance or the physical properties of the sealant composition are impaired.
상기 실리카 에어로겔 분말은 조성물의 내화 및 내열 특성을 개선해주는 것으로, 일반적으로 물유리 또는 TEOS(Tetra Ethyl Ortho Silicate), TMOS(Tetra Methyl Ortho Silicate)와 같은 알콕사이드(alkoxide)를 원료로 초임계 건조 및 상압 건조와 같은 에어로겔 합성 공정에 따라 제조된 것을 사용할 수 있으며, 공지된 다양한 제조방법에 의해 제조된 것을 모두 적용할 수 있다. 이때, 그 압도는 0.1~100㎛의 범위이고, 무정형 실리카 에어로겔 분말인 것이 바람직하나, 이를 반드시 제한하는 것은 아니다.The silica airgel powder improves the fire resistance and heat resistance properties of the composition, and is generally made of water glass or an alkoxide such as TEOS (Tetra Ethyl Ortho Silicate) or TMOS (Tetra Methyl Ortho Silicate), and is dried by supercritical drying and normal pressure. Those manufactured according to airgel synthesis processes such as can be used, and those manufactured by various known manufacturing methods can all be applied. At this time, the pressure is in the range of 0.1 to 100㎛, and it is preferable that it is amorphous silica airgel powder, but this is not necessarily limited.
상기 실리카 에어로겔 분말은 조성물 내 10~20중량부로 포함됨이 바람직한데, 그 함량이 상기한 범위를 벗어날 경우 충분한 내화성의 확보가 어렵거나, 실란트 조성물의 물성을 저해하기 때문이다.The silica airgel powder is preferably included in the composition in an amount of 10 to 20 parts by weight, because if the content exceeds the above range, it is difficult to secure sufficient fire resistance or the physical properties of the sealant composition are impaired.
아울러, 상기 실리카 에어로겔 분말은, 실리카 에어로겔 분말을 플라즈마 처리하고, 이를 인산염 수용액에 침지한 후, 건조하고 분쇄한 것을 사용하는 것이 더욱 바람직한바, 이러한 실리카 에어로겔 분말을 사용할 경우 그 내화 특성이 더욱 개선되는 것은 물론, 실란트 조성물의 전체적인 물성 저하가 없기 때문이다.In addition, it is more preferable to use the silica airgel powder by plasma treating the silica airgel powder, immersing it in an aqueous phosphate solution, drying and pulverizing it. When using this silica airgel powder, the fire resistance properties are further improved. Of course, this is because there is no deterioration in the overall physical properties of the sealant composition.
더욱 구체적으로, 실리카 에어로겔 분말에 공기, 산소, 질소 또는 이들을 결합한 가스를 1~20cc/min으로 주입하고, 50~100W의 전압을 인가하여 0.1~5분간 플라즈마 처리하고, 이를 2~3부피배의 인산염 수용액에 20~30℃ 정도의 온도에서 30~40분간 침지한 후, 건조하고, 0.1~100㎛로 분쇄한 것을 사용함이 바람직하다. 이때, 상기 인산염 수용액으로는 3~10중량% 농도의 인산암모늄 수용액을 사용하면 족한바, 인산염의 종류 및 농도를 제한하지 않는다.More specifically, air, oxygen, nitrogen, or a combination thereof is injected into the silica airgel powder at a rate of 1 to 20 cc/min, a voltage of 50 to 100 W is applied, plasma treatment is performed for 0.1 to 5 minutes, and the mixture is treated with 2 to 3 volumes of the silica airgel powder. It is preferable to use a product that is immersed in an aqueous phosphate solution at a temperature of about 20 to 30°C for 30 to 40 minutes, dried, and ground to 0.1 to 100㎛. At this time, it is sufficient to use an ammonium phosphate aqueous solution with a concentration of 3 to 10% by weight as the aqueous phosphate solution, and the type and concentration of the phosphate are not limited.
상기 나노 그래핀 플레이크는 연기 발생을 억제하고, 절연층으로 작용하여 열의 이동을 방해하여 난연성을 확보하는 것은 물론, 실란트 조성물의 강도 및 내열성을 개선하는 역할을 한다. 상기 나노 그래핀 플레이크를 제조하는 방법은 이 기술이 속하는 분야에서 공지이므로, 이에 대한 추가 설명은 생략한다.The nano graphene flakes suppress the generation of smoke, act as an insulating layer to prevent heat movement, ensure flame retardancy, and improve the strength and heat resistance of the sealant composition. Since the method for producing the nano graphene flakes is well known in the field to which this technology belongs, further description thereof will be omitted.
상기 나노 그래핀 플레이크는 조성물 내 10~20중량부로 포함됨이 바람직한데, 그 함량이 상기한 범위를 벗어날 경우 충분한 내화성의 확보가 어렵거나, 실란트 조성물의 물성을 저해하기 때문이다.The nano graphene flakes are preferably included in the composition in an amount of 10 to 20 parts by weight, because if the content exceeds the above range, it is difficult to secure sufficient fire resistance or the physical properties of the sealant composition are impaired.
다만, 상기 나노 그래핀 플레이크를 그대로 사용할 경우 실란트 조성물의 접착성이 저하된다는 문제가 있다.However, when the nano graphene flakes are used as is, there is a problem that the adhesiveness of the sealant composition is reduced.
이를 위하여 본 발명에서는 상기 나노 그래핀 플레이크를 플라즈마 처리하고, 이를 n-아미노에틸-아미노프로필트리메톡시 실란 에멀션에 침지한 후, 건조하고, 분쇄한 것을 사용함이 바람직하다.For this purpose, in the present invention, it is preferable to use the nano graphene flakes after plasma treatment, immersion in n-aminoethyl-aminopropyltrimethoxy silane emulsion, drying, and pulverization.
더욱 구체적으로, 실리카 에어로겔 분말에 공기, 산소, 질소 또는 이들을 결합한 가스를 1~20cc/min으로 주입하고, 50~100W의 전압을 인가하여 0.1~5분간 플라즈마 처리하고, 이를 2~3부피배의 n-아미노에틸-아미노프로필트리메톡시 실란 에멀션에 20~30℃ 정도의 온도에서 30~40분간 침지한 후, 건조하고, 10~1000nm의 입도로 분쇄한 것을 사용하는 것이다. More specifically, air, oxygen, nitrogen, or a combination thereof is injected into the silica airgel powder at a rate of 1 to 20 cc/min, a voltage of 50 to 100 W is applied, plasma treatment is performed for 0.1 to 5 minutes, and the mixture is treated with 2 to 3 volumes of the silica airgel powder. It is used by immersing in n-aminoethyl-aminopropyltrimethoxy silane emulsion at a temperature of 20-30°C for 30-40 minutes, drying, and pulverizing to a particle size of 10-1000 nm.
이때, 상기 n-아미노에틸-아미노프로필트리메톡시 실란 에멀션으로는 n-아미노에틸-아미노프로필트리메톡시 실란 5~70중량%, 에멀션화제 0.1~1중량% 및 잔부의 물을 균질기로 5,000~10,000rpm으로 30~60분간 교반하여서 되는 것을 사용한다. 상기 에멀션 내 n-아미노에틸-아미노프로필트리메톡시 실란의 직경은 0.1~1㎛일 수 있다. 그리고 상기 에멀션화제는 폴리옥시에틸렌 알킬 에테르, 폴리옥시에틸렌 알킬아릴 에테르, 폴리옥시에틸렌-옥시프로필렌 블록 공중합체, 소르비탄 지방산 에스테르, 폴리옥시에틸렌 소르비탄 지방산 에스테르, 폴리옥시에틸렌 소르비톨 지방산 에스테르, 글리세린 지방산 에스테르, 폴리옥시에틸렌 지방산 에스테르, 폴리옥시에틸렌알킬아민, 플루오로-함유 비이온성 에멀션화제, 알킬아민염, 4차 암모늄염, 알킬 피리디늄염, 알킬베타인, 알킬아민 산화물 및 포스파티딜클로린 중 1종 이상을 사용할 수 있다.At this time, the n-aminoethyl-aminopropyltrimethoxy silane emulsion includes 5 to 70% by weight of n-aminoethyl-aminopropyltrimethoxy silane, 0.1 to 1% by weight of emulsifier, and the remaining water at 5,000 ~ Use the mixture that can be stirred at 10,000 rpm for 30 to 60 minutes.
