구체적으로 본 발명에 의한 2액형 복층유리용 2차 실링 내화 실리콘 실란트 조성물은, 수산기말단 폴리실록산수지 100중량부, 수산화마그네슘 10~50중량부, 수산화알루미늄 10~30중량부, 할로겐계 난연제 0.01~0.1중량부, 인계 난연제 1~5중량부, 탄소섬유 10~50중량부, 탄산화 발전회 10~50중량부, 가소제 20~50중량부, 충전제 100~150중량부 및 백금 촉매 0.1~5중량부를 포함하는 주제부와; 실란 경화제를 포함하는 경화제부;의 2액형으로 구성되되, 상기 충전제는 규회석을 포함하는 것을 특징으로 한다.Specifically, the secondary sealing fireproof silicone sealant composition for two-component double-glazed glass according to the present invention contains 100 parts by weight of a hydroxyl-terminated polysiloxane resin, 10 to 50 parts by weight of magnesium hydroxide, 10 to 30 parts by weight of aluminum hydroxide, and 0.01 to 0.1 parts by weight of a halogen-based flame retardant. 1 to 5 parts by weight of phosphorus flame retardant, 10 to 50 parts by weight of carbon fiber, 10 to 50 parts by weight of carbonation power ash, 20 to 50 parts by weight of plasticizer, 100 to 150 parts by weight of filler, and 0.1 to 5 parts by weight of platinum catalyst with the subject part; It is composed of a two-component type of a curing agent containing a silane curing agent; characterized in that the filler includes wollastonite.

먼저, 본 발명은 주제부와 경화제부의 2액형으로 구성되는바, 상기 주제부와 경화제부는 10:0.5~2 부피비로 혼합되어 사용됨이 바람직하다. First, the present invention is composed of a two-component type of a main part and a curing agent part, and the main part and the curing agent part are preferably mixed and used in a volume ratio of 10:0.5 to 2.

상기 주제부는 수산기말단 폴리실록산수지 100중량부, 수산화마그네슘 10~50중량부, 수산화알루미늄 10~30중량부, 할로겐계 난연제 0.01~0.1중량부, 인계 난연제 1~5중량부, 탄소섬유 10~50중량부, 탄산화 발전회 10~50중량부, 가소제 20~50중량부, 충전제 100~150중량부 및 백금 촉매 0.1~5중량부를 포함한다.The main component includes 100 parts by weight of hydroxyl-terminated polysiloxane resin, 10 to 50 parts by weight of magnesium hydroxide, 10 to 30 parts by weight of aluminum hydroxide, 0.01 to 0.1 parts by weight of halogen-based flame retardant, 1-5 parts by weight of phosphorus-based flame retardant, and 10 to 50 parts by weight of carbon fiber. 10 to 50 parts by weight of carbonation power generation ash, 20 to 50 parts by weight of a plasticizer, 100 to 150 parts by weight of a filler, and 0.1 to 5 parts by weight of a platinum catalyst.

상기 수산기말단 폴리실록산수지는 실란트 조성물을 구성하는 주성분으로, 이 기술이 속하는 분야에서 이미 공지된 성분이다. 예시적으로, 수산기말단 폴리디메틸실록산 수지(Siloxanes and Silicones, di-Me, hydroxy-terminated cas no. 70131-67-8)를 사용할 수 있다. 이하, 주제부 내 '중량부'는 상기 수산기말단 폴리실록산수지 100중량부를 기준으로 한다.The hydroxyl-terminated polysiloxane resin is a main component constituting the sealant composition and is a component already known in the field to which this technology belongs. For example, a hydroxyl-terminated polydimethylsiloxane resin (Siloxanes and Silicones, di-Me, hydroxy-terminated cas no. 70131-67-8) may be used. Hereinafter, 'parts by weight' in the main part is based on 100 parts by weight of the hydroxyl-terminated polysiloxane resin.

상기 수산화마그네슘(mignesium dihydroxide)과 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. The magnesium hydroxide (mignesium dihydroxide) and aluminum hydroxide (aluminum trihyroxide) emit water vapor when decomposed by heat to dilute some combustion gases and absorb heat, which serves to prevent the spread of combustion. Used as a fire retardant additive.

상기 수산화마그네슘과 수산화알루미늄은 상기 수산기말단 폴리실록산수지 100중량부에 대하여 수산화마그네슘 10~50중량부 및 수산화알루미늄 10~30중량부로 포함됨이 바람직한데, 그 함량이 상기한 범위를 벗어날 경우 충분한 내화성의 확보가 어렵거나, 실란트 조성물의 물성을 저해하기 때문이다.The magnesium hydroxide and aluminum hydroxide are preferably included in 10 to 50 parts by weight of magnesium hydroxide and 10 to 30 parts by weight of aluminum hydroxide based on 100 parts by weight of the hydroxyl-terminated polysiloxane resin. This is because it is difficult or impairs the physical properties of the sealant composition.

상기 할로겐계 난연제는 비용이 저렴한 대표적인 난연제로, 예시적으로 브롬계 난연제를 들 수 있는바, 더욱 구체적으로 hexabromocyclododecane(HBCDD), tertrabromobispheol A(TBBPA) 중 1종 이상을 사용할 수 있다. The halogen-based flame retardant is a representative low-cost flame retardant, and exemplarily brominated flame retardants may be mentioned. More specifically, at least one of hexabromocyclododecane (HBCDD) and tertrabromobispheol A (TBBPA) may be used.

다만, 이러한 할로겐계 난연제는 환경문제가 대두될 수 있으므로, 그 사용량을 상기 수산기말단 폴리실록산수지 100중량부에 대하여 0.01~0.1중량부로 함이 바람직하다. 아울러, 친환경성이 요구되는 경우 이러한 할로겐계 난연제의 사용은 생략할 수 있다.However, since such a halogen-based flame retardant may cause environmental problems, it is preferable to use 0.01 to 0.1 parts by weight based on 100 parts by weight of the hydroxyl-terminated polysiloxane resin. In addition, when eco-friendliness is required, the use of such a halogen-based flame retardant can be omitted.

상기 인계 난연제로는 암모늄 폴리포스테이트(Ammonium Polyphosphate)를 사용할 수 있는바, 이는 자체 물성에 따라 화염을 받으면 팽창되어 탄화막을 형성하는 역할을 함으로써, 방화성능을 개선해준다. Ammonium polyphosphate can be used as the phosphorus-based flame retardant, which expands upon receiving a flame according to its physical properties and serves to form a carbonized film, thereby improving fire resistance.

상기 암모늄 폴리포스테이트는 상기 수산기말단 폴리실록산수지 100중량부에 대하여 1~5중량부만큼 포함됨이 바람직하다. The ammonium polyphosphate is preferably included in an amount of 1 to 5 parts by weight based on 100 parts by weight of the hydroxyl-terminated polysiloxane resin.

상기 탄소섬유는 연기 발생을 억제하고, 절연층으로 작용하여 열의 이동을 방해하여 난연성을 확보하는 것은 물론, 실란트 조성물의 강도 및 내열성을 개선하는 역할을 한다.The carbon fiber suppresses smoke generation, acts as an insulating layer to prevent heat transfer, secures flame retardancy, and serves to improve the strength and heat resistance of the sealant composition.

이러한 탄소섬유로는 질소분위기 하에서 600~1000℃에서 30~100분간 열처리하고, 상기 열처리된 탄소섬유를 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.These carbon fibers are heat treated at 600 to 1000 ° C. for 30 to 100 minutes under a nitrogen atmosphere, and the heat-treated carbon fibers are immersed in 2 to 3 times the volume of an aqueous phosphate solution at a temperature of about 20 to 30 ° C. for 30 to 40 minutes. , it is preferable to use dried and pulverized to 0.1 ~ 100㎛. At this time, as the phosphate aqueous solution, it is sufficient to use an ammonium phosphate aqueous solution having a concentration of 3 to 10% by weight, and the type and concentration of the phosphate are not limited.

통상 백금 촉매가 사용된 실란트 조성물은 인장강도가 저하되는 특징이 있는바, 본 발명은 상기 탄소섬유를 통해 이러한 단점을 개선함은 물론, 내열, 내화특성 및 전체적인 실란트 조성물의 물성을 개선하는 것이다.In general, sealant compositions using platinum catalysts have a characteristic of lowering tensile strength, and the present invention is to improve heat resistance, fire resistance, and overall physical properties of the sealant composition as well as improve these disadvantages through the carbon fiber.

상기 탄소섬유는 상기 수산기말단 폴리실록산수지 100중량부에 대하여 10~50중량부로 포함됨이 바람직하다.The carbon fiber is preferably included in an amount of 10 to 50 parts by weight based on 100 parts by weight of the hydroxyl-terminated polysiloxane resin.

상기 탄산화 발전회는 내화 및 난연성을 현저히 높여줄 뿐 아니라, 탄소섬유와의 병용시 실란트 조성물을 물성 및 내열성을 현저히 개선하는 역할을 한다.The carbonation power generation ash not only remarkably improves fire resistance and flame retardancy, but also significantly improves physical properties and heat resistance of the sealant composition when used in combination with carbon fiber.

석탄 연소 후에 남아있는 물질 중 하나인 발전회(비회, fly ash)는 SiO2, CaO, Fe2O3, Al2O3, MgO, SO3, Na2O 등을 주성분으로 하는바, 이를 탄산화할 경우 우수한 내화 특성을 발휘하는 것이다.Power ash (fly ash), one of the materials remaining after coal combustion, is mainly composed of SiO 2 , CaO, Fe 2 O 3 , Al 2 O 3 , MgO, SO 3 , Na 2 O, etc., which is carbonated If so, it exhibits excellent fire resistance properties.

이러한 탄산화 발전회를 제조하는 방법은, 발전회에 물을 1:1~2중량비로 혼합하고, 이에 이산화탄소를 pH가 9~10이 될때까지 주입한 후, 여과 및 건조하고, 상기 건조된 건조물을 2~3부피배의 인산염 수용액에 20~30℃의 온도에서 30~40분간 침지한 후, 건조하고 0.1~100㎛로 분쇄하는 것이다. 이때, 상기 인산염 수용액으로는 3~10중량% 농도의 인산암모늄 수용액을 사용하면 족한바, 인산염의 종류 및 농도를 제한하지 않는다.In the method for producing carbonation power generation ash, water is mixed with power generation ash at a weight ratio of 1:1 to 2, carbon dioxide is injected thereto until the pH is 9 to 10, followed by filtering and drying, and the dried product is It is immersed in 2 to 3 times the volume of phosphate aqueous solution at a temperature of 20 to 30 ° C for 30 to 40 minutes, dried, and pulverized to 0.1 to 100 μm. At this time, as the phosphate aqueous solution, it is sufficient to use an ammonium phosphate aqueous solution having a concentration of 3 to 10% by weight, and the type and concentration of the phosphate are not limited.

통상 탄산화 발전회의 제조시 pH가 7~8정도가 되도록 이산화탄소를 주입하는데, 이러한 경우 오히려 전체적인 실란트 조성물의 물성이 좋지 못한바, 본 발명은 pH 9~10이 되도록 이산화탄소를 주입하고, 그 내화성능을 더욱 개선하기 위하여 인산암모늄 수용액에 침지하여 사용하는 것이다. In general, carbon dioxide is injected so that the pH is about 7 to 8 during the production of carbonation power generation ash, but in this case, the physical properties of the overall sealant composition are not good. In the present invention, carbon dioxide is injected so that the pH is 9 to 10, For further improvement, it is used after being immersed in an aqueous solution of ammonium phosphate.

즉, 이러한 탄산화 발전회는 연소시 인산염에 의해 1차 적으로 탄화막을 형성하고, 발전회에 존재하는 Ca, Mg, Si 성분이 세라믹을 형성시켜 산소와 열을 차단하게 된다.That is, such carbonation power generation ash primarily forms a carbonized film by phosphate during combustion, and Ca, Mg, and Si components present in power generation ash form a ceramic to block oxygen and heat.

상기 가소제는 실란트 조성물의 성질을 부드럽고 유동적일 수 있도록 하고, 지나치게 경직되어 굳는 것을 막아주는 역할을 하는 것으로, 폴리실록산 오일이 사용될 수 있다.The plasticizer serves to make the properties of the sealant composition soft and fluid and prevents it from being hardened due to excessive rigidity, and polysiloxane oil may be used.

상기 가소제는 상기 수산기말단 폴리실록산수지 100중량부에 대하여 20~50중량부로 포함됨이 바람직한바, 그 함량이 너무 적거나 많으면 가소제로서의 기능이 충분히 발휘될 수 없거나, 오히려 인장강도를 저하시키기 때문이다.The plasticizer is preferably included in an amount of 20 to 50 parts by weight based on 100 parts by weight of the hydroxyl-terminated polysiloxane resin, because if the content is too small or too large, the function as a plasticizer cannot be sufficiently exhibited, or rather, the tensile strength is lowered.

상기 충전제는 실란트의 강도, 경도 등을 적절하게 조절해주는 물질로서, 규회석을 사용함이 바람직하다. 상기 규회석은 실란트 조성물의 내화 특성을 개선하면서도, 결합력을 높여주는 역할을 한다.The filler is a material that appropriately adjusts the strength, hardness, etc. of the sealant, and it is preferable to use wollastonite. The wollastonite improves the fire resistance of the sealant composition and serves to increase bonding strength.

아울러, 상기 충전제는 세륨산화물(CeO2)을 더 포함하는 것이 바람직하다. 상기 세륨산화물은 내열 및 난연 특성을 개선해준다. 이때, 상기 규회석과 세륨산화물은 1:0.5~1 중량비로 사용됨이 바람직하다.In addition, the filler preferably further includes cerium oxide (CeO 2 ). The cerium oxide improves heat resistance and flame retardancy. At this time, the wollastonite and cerium oxide are preferably used in a weight ratio of 1:0.5 to 1.

상기 충전제는 상기 수산기말단 폴리실록산수지 100중량부를 기준으로 100~150중량부로 포함됨이 바람직한데, 그 함량이 너무 적으면 물성의 향상 효과가 미미하고, 과량이 되면 전체적인 접착력이 저하되는 등의 문제가 있기 때문이다. The filler is preferably included in an amount of 100 to 150 parts by weight based on 100 parts by weight of the hydroxyl-terminated polysiloxane resin. Because.

상기 백금 촉매는 경화 속도를 촉진시키는 경화촉진제로서의 역할을 하는 것이며, 최종적으로 백금은 실란트에 자기 소화성을 부여해주는 역할을 한다.The platinum catalyst serves as a curing accelerator for accelerating the curing rate, and finally, platinum serves to impart self-extinguishing properties to the sealant.

상기 백금 촉매로는 알코올, 에테르, 알데히드 등에 혼합된 염화 백금산 또는 염화 백금산 화합물 및 인산계 백금[Pt{P(OC6H5)3}4, Pt{P(C6H5)3}4, Pt{P(CH3)3}4, Pt{P(C4H9)3}4, Pt{P(OCH3)3}4, Pt{P(OC6H5)3}3, Pt{P(C6H5)3}3, Pt{P(C6H5)(C2H5)2}4, Pt{P(OC6H5)(OC2H5)2}4, Pt{P(C6H5)2(OC2H5)}4, Pt{P(CH3)2(OC4H9)}4) 등을 포함하는 것일 수 있으며, 알코올, 이소프로필 알코올, 벤젠, 자일렌 등 유기용제에 분산시켜서 사용되는 것일 수도 있음은 물론이다. The platinum catalyst includes chloroplatinic acid or a chloroplatinic acid compound mixed with alcohol, ether, aldehyde, etc., and phosphoric acid-based platinum [Pt{P(OC 6 H 5 ) 3 } 4 , Pt{P(C 6 H 5 ) 3 } 4 , Pt{P(CH 3 ) 3 } 4 , Pt{P(C 4 H 9 ) 3 } 4 , Pt{P(OCH 3 ) 3 } 4 , Pt{P(OC 6 H 5 ) 3 } 3 , Pt{ P(C 6 H 5 ) 3 } 3 , Pt{P(C 6 H 5 )(C 2 H 5 ) 2 } 4 , Pt{P(OC 6 H 5 )(OC 2 H 5 ) 2 } 4 , Pt {P(C 6 H 5 ) 2 (OC 2 H 5 )} 4 , Pt{P(CH 3 ) 2 (OC 4 H 9 )} 4 ) and the like, and alcohol, isopropyl alcohol, benzene Of course, it may be used after being dispersed in an organic solvent such as xylene.

상기 백금 촉매는 상기 수산기말단 폴리실록산수지 100중량부에 대하여 0.1~5중량부만큼 포함될 수 있는바, 그 함량이 너무 많으면 단가가 높아지고, 그 함량이 너무 적으면 경화 촉진의 효과가 미미하기 때문이다. The platinum catalyst may be included in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of the hydroxyl-terminated polysiloxane resin, because if the content is too large, the unit price increases, and if the content is too small, the effect of accelerating curing is insignificant.

상기 실란 경화제는 실란트 조성물의 경화를 위한 것으로, 예컨데 메틸트리(에틸메틸케톡심)실란(Methyltri(ethylmethylketoxime)silane), 테트라(메틸 에틸 케토옥심) 실란 등의 옥심계 실란 경화제, 또는 메틸 트리메톡시 실란, 비닐 트리메톡시 실란 등의 알콕시계 실란 경화제를 단독으로, 또는 이들을 2 이상 조합하여 사용할 수 있다.The silane curing agent is for curing the sealant composition, for example, an oxime-based silane curing agent such as methyltri(ethylmethylketoxime)silane, tetra(methyl ethyl ketoxime) silane, or methyl trimethoxy Alkoxy-based silane curing agents such as silane and vinyl trimethoxy silane may be used alone or in combination of two or more thereof.
