Abstract
Description
본 발명은 2액형 복층유리용 내화 실란트 조성물에 관한 것으로, 더욱 상세하게는 수산화마그네슘, 수산화알루미늄 등의 내화 첨가제를 포함하는 실란트 조성물을 제조함으로써, 내화성이 향상되어 방화성이 개선되는 2액형 복층유리용 내화 실란트 조성물에 관한 것이다.The present invention relates to a two-component double-glazed fire-resistant sealant composition, and more particularly, to a two-component double-glazed glass having improved fire resistance by preparing a sealant composition containing fire-resistant additives such as magnesium hydroxide and aluminum hydroxide. It relates to a fire resistant sealant composition.
복층유리(Double Glazing)란, 두 장의 판유리 사이에 공간을 두어 최소 두 겹으로 만들어진 판유리로 이는 일반 단판유리가 갖는 결점을 보완한 것이다. 이러한 복층유리는 단열유리(insulating glass, IG unit)라고도 한다. Double glazing is a sheet glass made of at least two layers with a space between two sheets of glass, which compensates for the shortcomings of ordinary single-pane glass. This double-glazed glass is also called insulating glass (IG unit).
상기 복층유리는 유리와 유리 사이에 마감재로 실란트 조성물이 사용되는데, 이를 복층유리 2차 실링이라고 부른다.In the double-glazed glass, a sealant composition is used as a finishing material between glass and glass, which is called double-glazed secondary sealing.
종래 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.Conventionally, these sealants have pursued only functional purposes of watertightness and airtightness. Recently, these sealants also require fire protection performance, and a reliable blocking effect against toxic gases and heat by sealing is required.
내화성 실란트의 선행문헌으로는 대한민국 등록특허 제10-0674035호 및 등록특허 제10-2039767호가 게시되어 있다. Korean Patent Registration No. 10-0674035 and Korean Patent Registration No. 10-2039767 have been published as prior literature on fire-resistant sealants.
상기 대한민국 등록특허 제10-0674035호는 교차결합 유기규소 화합물, 규회석 등을 포함하여 내화성을 개선하였고, 상기 대한민국 등록특허 제10-2039767호에서는 팽창 흑연, 난연제를 포함하여 방화재용 실란트 조성물을 제조하였다.Korean Patent Registration No. 10-0674035 improved fire resistance by including a cross-linked organosilicon compound, wollastonite, etc., and Korean Patent Registration No. 10-2039767 prepared a sealant composition for fire retardant materials by including expanded graphite and a flame retardant. .
그러나 선행문헌들의 어디에서도 수산화마그네슘, 수산화알루미늄, 할로겐계 난연제 및 인계 난연제 등을 이용하여 내화성을 개선한 예는 없었다.However, there is no example in which fire resistance is improved by using magnesium hydroxide, aluminum hydroxide, a halogen-based flame retardant, a phosphorus-based flame retardant, or the like, anywhere in the prior literature.
따라서, 본 발명의 목적은 수산화마그네슘, 수산화알루미늄, 할로겐계 난연제, 인계 난연제, 미네랄섬유, 팽창 흑연 등의 내화 첨가제를 포함하여 우수한 접착성, 기밀성을 가지면서도, 내화성이 우수하여 방화성능이 개선된 2액형 복층유리용 내화 실란트 조성물을 제공하는 데 있다.

구체적으로 본 발명에 의한 2액형 복층유리용 내화 실란트 조성물은, 폴리설파이드 폴리머, 내화 첨가제, 가소제, 충전제 및 백금 촉매를 포함하는 주제부와, 이산화망간 및 가소제를 포함하는 경화제부의 2액형으로 구성되되, 상기 내화 첨가제는 수산화마그네슘, 수산화알루미늄, 할로겐계 난연제, 인계 난연제, 미네랄섬유 및 팽창 흑연을 포함하고, 상기 충전제는 규회석을 포함하는 것을 특징으로 한다.

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 주제는 폴리설파이드 폴리머, 내화 첨가제, 가소제, 충전제 및 백금 촉매를 포함한다.The subject includes polysulfide polymers, refractory additives, plasticizers, fillers and platinum catalysts.
상기 폴리설파이드 폴리머는 실란트 조성물을 구성하는 주성분으로, 이 기술이 속하는 분야에서 이미 공지된 성분이다. 이하, 주제부 내 '중량부'는 상기 폴리설파이드 폴리머 100중량부를 기준으로 한다.The polysulfide polymer is a main component constituting the sealant composition and is a component already known in the field to which this technology belongs. Hereinafter, 'parts by weight' in the subject part is based on 100 parts by weight of the polysulfide polymer.
상기 내화 첨가제는 실란트 조성물의 접착성 및 수밀성을 저하하지 않으면서도, 내화성을 현저히 개선해주는 것으로, 보다 구체적으로는 수산화마그네슘(mignesium dihydroxide), 수산화알루미늄(aluminium trihyroxide), 할로겐계 난연제, 인계 난연제, 미네랄섬유 및 팽창 흑연를 포함함이 바람직하다.The fire-resistant additive significantly improves fire resistance without deteriorating the adhesiveness and watertightness of the sealant composition, and more specifically, magnesium hydroxide (mignesium dihydroxide), aluminum hydroxide (aluminium trihyroxide), halogen-based flame retardants, phosphorus-based flame retardants, minerals It is preferred to include fibers and expanded graphite.
상기 수산화마그네슘과 수산화알루미늄은 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 and aluminum hydroxide are used as fireproofing additives because they emit water vapor when decomposed by heat to dilute some combustion gases and absorb heat to prevent the spread of combustion.
상기 수산화마그네슘과 수산화알루미늄은 상기 폴리설파이드 폴리머 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 with respect to 100 parts by weight of the polysulfide polymer. This is because it is difficult or deteriorates 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 폴리설파이드 폴리머 100중량부에 대하여 0.01~0.1중량부로 함이 바람직하다. 아울러, 친환경성이 요구되는 경우 이러한 할로겐계 난연제의 사용은 생략할 수 있다.However, since these halogen-based flame retardants 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 polysulfide polymer. 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 폴리설파이드 폴리머 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 polysulfide polymer.
상기 미네랄 섬유는 암면, Rock wool 등으로 호칭되는 것으로, 우수한 내화성을 갖는다.The mineral fiber is called rock wool, rock wool, etc., and has excellent fire resistance.
상기 미네랄 섬유는 상기 폴리설파이드 폴리머 100중량부에 대하여 10~20중량부만큼 포함됨이 바람직하다. The mineral fibers are preferably included in an amount of 10 to 20 parts by weight based on 100 parts by weight of the polysulfide polymer.
상기 팽창 흑연은 탄소쇄로 이루어지는 층간구조로, 열을 가하면 팽창되는 특성을 가지는바, 대부분의 경우 연기 발생을 억제하고, 팽창된 카본층이 절연층으로 작용하여 열의 이동을 방해하여 난연성을 확보한다. The expanded graphite has an interlayer structure composed of carbon chains, and has a property of expanding when heat is applied. In most cases, smoke generation is suppressed, and the expanded carbon layer acts as an insulating layer to prevent the movement of heat to secure flame retardancy. .
상기 팽창 흑연은 상기 폴리설파이드 폴리머 100중량부에 대하여 5~20중량부만큼 포함됨이 바람직한데, 그 함량이 너무 적으면 내화성을 기대하기 어렵고, 과량이 되면 분산성이 떨어지고 실란트 조성물의 물성을 저해하는 등의 단점이 있기 때문이다. The expanded graphite is preferably included in an amount of 5 to 20 parts by weight based on 100 parts by weight of the polysulfide polymer. If the content is too small, it is difficult to expect fire resistance, and if the content is excessive, dispersibility is reduced and the physical properties of the sealant composition are deteriorated. This is because there are disadvantages such as
상기 가소제는 실란트 조성물의 성질을 부드럽고 유동적일 수 있도록 하고, 지나치게 경직되어 굳는 것을 막아주는 역할을 하는 것으로, 프탈레이트계 가소제를 사용할 수 있다. 상기 프탈레이트계 가소제는 디부틸 프탈레이트(dibutyl phthalate), 부틸벤질 프탈레이트(butylbenzyl phthalate) 및 디옥틸프탈레이트(dioctyl phthalate) 중 1종 이상을 사용하는 것이 바람직하다.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 a phthalate-based plasticizer may be used. It is preferable to use at least one of dibutyl phthalate, butylbenzyl phthalate, and dioctyl phthalate as the phthalate-based plasticizer.
상기 가소제는 폴리설파이드 폴리머 100중량부에 대하여, 20~50중량부임이 바람직한바, 그 함량이 너무 적거나 많으면 가소제로서의 기능이 충분히 발휘될 수 없거나, 오히려 인장강도를 저하시키기 때문이다.The plasticizer is preferably 20 to 50 parts by weight based on 100 parts by weight of the polysulfide polymer, because too little or too much of the plasticizer function cannot be sufficiently exhibited, or rather, tensile strength is lowered.
상기 충전제는 실란트의 강도, 경도 등을 적절하게 조절해주는 물질로서, 규회석을 사용함이 바람직하다. 아울러, 선택적으로 탄산칼슘, 실리카 중 1종 이상을 더 사용할 수 있다.The filler is a material that appropriately adjusts the strength, hardness, etc. of the sealant, and it is preferable to use wollastonite. In addition, optionally, one or more of calcium carbonate and silica may be further used.
상기 규회석, 탄산칼슘 및 실리카는 실란트의 물성이 저하되는 현상을 방지하면서도, 결합력을 증가시킨다. 특히, 상기 규회석은 실란트 조성물의 내화 특성을 개선하면서도, 결합력을 높여주는 역할을 한다.The wollastonite, calcium carbonate and silica increase bonding strength while preventing degradation of physical properties of the sealant. In particular, the wollastonite plays a role of improving the fire resistance properties of the sealant composition and increasing the bonding force.
상기 충전제는 상기 폴리설파이드 폴리머 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 polysulfide polymer. If the content is too small, the effect of improving physical properties is insignificant, and if the content is excessive, the overall adhesive strength is reduced. to be.
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 폴리설파이드 폴리머 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 polysulfide polymer, 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 경화제부는 이산화망간 및 가소제를 포함한다.The curing agent part includes manganese dioxide and a plasticizer.
상기 이산화망간은 경화제부의 주요 물질로서, 상기 폴리설파이드 폴리머를 경화시키는 역할을 한다. 상기 폴리설파이드 폴리머의 경화제로 작용하는 이산화망간은 이 기술이 속하는 분야에서 충분히 공지된 것이므로, 이에 대한 상세한 설명은 생략한다. The manganese dioxide is a main material of the curing agent part and serves to cure the polysulfide polymer. Since manganese dioxide, which acts as a curing agent for the polysulfide polymer, is well known in the art, a detailed description thereof will be omitted.
상기 가소제는 상기 주제부와 동일하게 프탈레이트계 가소제를 사용할 수 있다. As the plasticizer, a phthalate-based plasticizer may be used in the same way as the main part.

상기 폴리에테르이미드(Polyetherimide) 나노섬유는 폴리에테르이미드(Polyetherimide)를 전기방사하여 제조되는 것으로, 내화성이 우수하여 실란트 조성물의 접착성, 수밀성 등을 저해하지 않으면서도, 방화특성을 향상시킨다. 이러한 폴리에테르이미드 나노섬유는 그 입도가 50~400nm임이 바람직하다.The polyetherimide nanofibers are prepared by electrospinning polyetherimide, and have excellent fire resistance, thereby improving fire resistance without impairing adhesion and watertightness of the sealant composition. These polyetherimide nanofibers preferably have a particle size of 50 to 400 nm.
상기 폴리에테르이미드(Polyetherimide) 나노섬유는 상기 폴리설파이드 폴리머 100중량부를 기준으로, 1~5중량부만큼 사용됨이 바람직하다. The polyetherimide nanofibers are preferably used in an amount of 1 to 5 parts by weight based on 100 parts by weight of the polysulfide polymer.

상기 금속수산화물은 표면이 붕산으로 처리된 것으로, 금속수산화물로는 수산화마그네슘, 수산화알루미늄 등이 사용되며, 붕산은 오르토붕산, 메타붕산, 사붕산 등이 사용될 수 있다. 이와 같이 붕산으로 처리된 금속수산화물은 연소시 고체막을 형성하여 난연성을 향상시키는 차르(char)의 형성을 용이하게 하는 것인바, 실란트 조성물의 방화성능을 개선해준다. The surface of the metal hydroxide is treated with boric acid, magnesium hydroxide, aluminum hydroxide, etc. are used as the metal hydroxide, and orthoboric acid, metaboric acid, tetraboric acid, etc. may be used as the boric acid.

상기 아연 붕산염(zinc borate)은 화염을 받으면 투명한 보호막과 숯(char)층을 형성하여 산소의 투입을 제한함으로써, 탄소의 산화를 막는다. 또한, 상기 아연붕산염은 고온에서 흡열 반응을 일으키므로, 내열성 향상에 도움을 준다. 특히, 상기 아연 붕산염은 단독으로 사용시 그 효과가 미미하나, 상기 내화 첨가제와의 병용시 시너지 효과를 나타낸다.When the zinc borate receives flame, it forms a transparent protective film and a char layer to limit the input of oxygen, thereby preventing oxidation of carbon. In addition, since the zinc borate causes an endothermic reaction at high temperature, it helps to improve heat resistance. In particular, the effect of the zinc borate is insignificant when used alone, but shows a synergistic effect when used in combination with the refractory additive.
상기 아연 붕산염은 상기 폴리설파이드 폴리머 100중량부를 기준으로, 1~5중량부만큼 사용됨이 바람직하다. The zinc borate is preferably used in an amount of 1 to 5 parts by weight based on 100 parts by weight of the polysulfide polymer.
