Description

화재차단 조성물 및 이로부터 제조되는 팽창성 화염차단 벨트{Fire Sealing Composition and Intumescent FireSealing Belt}FIRE SEALING COMPOSITION AND INSULATED FIRE SEALING BELT FIELD OF THE INVENTION [0001]

본 발명은 화재차단 조성물 및 이를 이용한 팽창성 화염차단벨트의 제조방법에 관한 것으로, 보다 상세하게는 화재발생 시 팽창성 화염차단 벨트가 팽창하여 건축물 내부의 입상관통부, 벽체관통부를 물리적으로 차폐하여 화염 및 연기의 이동통로를 차단하는 화재차단 조성물 및 이를 이용한 팽창성 화염차단벨트의 제조방법에 관한 것이다.The present invention relates to a fire-shielding composition and a method of manufacturing an expandable flame blocking belt using the fire-shielding composition. More particularly, the present invention relates to a fire- And to a method of manufacturing an expandable flame blocking belt using the same.

고층 빌딩 등과 같은 밀폐된 공간 내의 화재, 연기 및 가스는 생명에 상당한 위험을 줄 수 있다. 화재가 구조물의 바닥과 천정 사이의 공간에서 발생하는 경우, 화재와 이로 인한 연기 및 가스는 빌딩 내 다른 개방 공간, 특히 화재의 발생 지점 보다 높은 개방 공간으로 빈번하게 확산되는 경향이 있다.Fire, smoke and gas in enclosed spaces such as high-rise buildings can pose a significant risk to life. When a fire occurs in the space between the floor of the structure and the ceiling, the fire and the resulting smoke and gas tend to spread frequently to other open spaces in the building, especially to open spaces higher than the point of fire occurrence.

바닥, 벽 및 천정 내 구멍 그리고 도관, 파이프, 전선 등은 “관통구”로 공지되어 있다. 이러한 관통구는 내화성 물질에 의해 보호되지 않는 경우, 화재, 연기 및 가스에 대한 내성이 낮은 영역을 제공하며, 주로 열, 불꽃, 연기 및 가스의 굴뚝으로 작용할 수도 있다.The bottoms, walls and ceiling holes and conduits, pipes, wires, etc. are known as "through holes". These through-holes provide areas of low resistance to fire, smoke and gas when not protected by refractory materials, and may act primarily as chimneys of heat, flame, smoke and gas.

또한, 건축물의 내부 관통부의 마감처리는 시멘트 등의 불연재료로 하였으나, 금속배관의 마감처리(보온재 등)부분 및 플라스틱 배관등은 화염에 노출되면 녹아내려 녹아내린 부분의 내화성능확보가 불가능해 질 수 있다.In addition, although the finishing treatment of the internal penetration portion of the building is made of a non-combustible material such as cement, the finishing treatment (heat insulating material, etc.) of the metal piping and the plastic piping are not able to secure the refractory performance of the melted and melted portion when exposed to the flame .

따라서 이러한 문제점을 해결하기 위하여, 일반적으로 그라파이트를 사용하여 난연성을 향상시킨 건축자재가 제안되었으며, 그 일예로서 대한민국 특허 공개번호 제2005-77551호에서는 건축용 단열재, 충격보강재, 및 건축 내외장재에 사용되는 난연성능이 우수한 폴리이소시아누레이트 발포체를 제조한 것으로서 팽창성 흑연을 사용하여 화재 시 탄화막을 형성하여 이소시아네이트간의 삼량화 반응을 위하여 NCO/OH 비율을 증가시킨 후, 삼량화 촉매를 사용하여 이소시아네이트 간의 삼량화 반응을 일으키게 하여 난연성을 개선할 수 있도록 하고 있다. In order to solve these problems, a building material improved in flame retardancy by using graphite has been proposed. As an example thereof, Korean Patent Publication No. 2005-77551 discloses a flame retardant for use in architectural thermal insulation, impact reinforcement, A polyisocyanurate foam having excellent performance was produced. Expandable graphite was used to form a carbonized film in case of fire, thereby increasing the NCO / OH ratio for the trimerization reaction between isocyanates. Then, trimerization between isocyanates was carried out using a trimerization catalyst So that the flame retardancy can be improved.

그러나 화재 발생시 폴리이소시아누레이트 발포체에 직접 열이 전달됨에 따라 유해가스가 여전히 발생될 뿐만 아니라, 건축용 패널에 전면적인 탄화막의 생성이 어려움에 따라 난연성이 저하되는 문제점이 남아있다.However, since heat is directly transferred to the polyisocyanurate foam when a fire occurs, harmful gas is still generated, and there is a problem that flame retardancy is deteriorated due to difficulty in producing a full-scale carbon film on a building panel.

이하는 본 발명의 화재차단 조성물에 관해 보다 구체적으로 설명한다.Hereinafter, the fire-shielding composition of the present invention will be described in more detail.

본 발명의 화재차단 조성물은 수용성 에멀젼 100 중량부에 대하여, 인계난연제 10 ~ 50 중량부, 무기질난연필러 70 ~ 130 중량부, 팽창흑연 50 ~ 100 중량부 및 유리섬유 1 ~ 10 중량부를 포함하는 것을 특징으로 한다.The fire-shielding composition of the present invention comprises 10 to 50 parts by weight of a phosphorus-based flame retardant, 70 to 130 parts by weight of an inorganic flame-retardant filler, 50 to 100 parts by weight of expanded graphite and 1 to 10 parts by weight of glass fiber, based on 100 parts by weight of the water- .

상기 수용성 에멀젼은 접착력, 제품의 방수성, 강도 및 내마모성에 영향을 미치는 것으로, 구체적으로 예를 들면, 수성 아크릴계 에멀젼, 수성 우레탄계 에멀젼 및 수성 에틸렌비닐아세테이트계 에멀젼 등에서 선택되는 어느 하나 또는 둘 이상의 혼합물을 사용할 수 있으나 반드시 이에 제한되는 것은 아니다. 수성 에멀젼의 고형분은 특히 제한되지는 않지만, 제품의 방수성, 강도 및 성형의 용이성을 위하여 40 ~ 80 중량%, 좋게는 50 ~ 70중량%인 것이 바람직하다. The water-soluble emulsion affects the adhesive strength, the waterproof property, the strength and the abrasion resistance of the product. Specifically, for example, any one or a mixture of two or more selected from an aqueous acrylic emulsion, an aqueous urethane emulsion and an aqueous ethylene vinyl acetate emulsion But is not necessarily limited thereto. The solid content of the aqueous emulsion is not particularly limited, but is preferably 40 to 80% by weight, more preferably 50 to 70% by weight, for the waterproofness, strength and ease of molding of the product.

상기 인계난연제는 화재 시 탄화막을 형성하여 단열성을 높이는 재료가 바람직하다. 구체적으로 예를 들면, 트리스-2-클로로에틸포스페이트, 트리스-2-클로로프로필포스페이트, 이소프로필페닐디페닐포스페이트, 트리크레실포스페이트, 트리페닐포스페이트, 트리에틸포스페이트, 멜라민포스페이트 및 암모늄포스페이트등에서 선택되는 어느 하나 또는 둘 이상의 혼합물일 수 있으나, 반드시 이에 제한되지는 않는다. 그 함량은 상기 수용성 에멀젼 100 중량부에 대하여, 10 ~ 50 중량부 사용하는 것이 바람직하며, 10 중량부 미만인 경우, 발포율이 떨어져 내화성능이 저하될 우려가 있고, 50 중량부를 초과하는 경우, 팽창하여 깨질 우려가 있어 좋지 않아 상기 범위를 만족하는 것이 바람직하다.The phosphorus-based flame retardant is preferably a material that forms a carbonized film during a fire to enhance the heat insulating property. Specifically, there may be mentioned, for example, tris-2-chloroethyl phosphate, tris-2-chloropropyl phosphate, isopropylphenyl diphenyl phosphate, tricresyl phosphate, triphenyl phosphate, triethyl phosphate, melamine phosphate and ammonium phosphate May be any one or a mixture of two or more, but is not necessarily limited thereto. The content thereof is preferably 10 to 50 parts by weight based on 100 parts by weight of the water-soluble emulsion. When the amount is less than 10 parts by weight, the foamability may be lowered and the refractory performance may be deteriorated. When the amount exceeds 50 parts by weight, So that it is preferable to satisfy the above range.

상기 무기질난연필러는 제품에 단열성을 부여하고, 난연성의 주 기능과 더불어 제품의 강도 및 점도유지에 영향을 미치는 것으로서, 구체적으로 예를 들면, 수산화알루미늄, 수산화마그네슘, 산화안티몬, 주석산아연, 붕산아연, 인산암모늄, 지르코늄 및 탄산칼슘 등으로 이루어진 군에서 선택되는 어느 하나 또는 둘 이상의 혼합물을 사용할 수 있다.The inorganic flame-retardant filler imparts heat insulation to the product, affects the main function of the flame retardancy and affects the strength and viscosity of the product, and specifically includes, for example, aluminum hydroxide, magnesium hydroxide, antimony oxide, zinc stannate, zinc borate , Ammonium phosphate, zirconium, calcium carbonate and the like can be used.

상기 무기질난연필러의 함량은 상기 수용성 에멀젼 100 중량부에 대하여, 70 ~ 130 중량부 사용하며, 70 중량부 미만인 경우 성형품의 강도가 저하되는 문제가 발생되고, 130 중량부를 초과하는 경우 제품의 점도 상승으로 인하여 제품성형에 영향을 미치게 되므로 상기범위를 만족하는 것이 바람직하다.The content of the inorganic flame retardant filler is 70 to 130 parts by weight based on 100 parts by weight of the water-soluble emulsion. When the amount is less than 70 parts by weight, the strength of the molded product is lowered. When the amount is more than 130 parts by weight, And therefore it is preferable to satisfy the above range.

본 발명의 팽창흑연은 카본을 3,000℃ 이상에서 추출한 탄소조직으로 100 ~ 200℃에서 발포팽창을 시작하여 40 ~ 350% 까지 팽창하고 화재발생시 화염전파를 차단하여 단열재의 보호 및 유해가스방출을 차단하는 목적으로 사용하며, 구체적으로 예를 들면, 입경이 10 ~ 1,000 ㎛인 것을 사용하는 것이 본 발명의 목적인 단열재의 보호 및 유해가스를 차단하기에 가장 바람직하나, 반드시 이에 제한되는 것은 아니다.The expanded graphite of the present invention is a carbon structure extracted from carbon at a temperature of 3,000 ° C or higher. It expands at a temperature of 100 to 200 ° C and expands to 40 to 350%. When a fire occurs, it blocks flame propagation and protects the insulating material and prevents the release of noxious gas For example, it is most preferable to use a material having a particle size of 10 to 1,000 占 퐉 for protecting the heat insulator and shielding harmful gas, which are the object of the present invention, but the present invention is not limited thereto.

상기 팽창흑연의 함량은 상기 수용성 에멀젼 100 중량부에 대하여, 50 ~ 100 중량부 사용하는 것이 화염전파를 차단하고 단열재의 보호 및 유해가스를 차단하기에 바람직하다. 50 중량부 미만인 경우 본 발명의 목적을 달성하기 어려우며, 방염성이 떨어지고, 100 중량부를 초과하는 경우 원가상승 및 제품성형에 영향을 가지게 되므로 상기 범위를 만족하는 것이 바람직하다.The content of the expanded graphite is preferably 50 to 100 parts by weight based on 100 parts by weight of the water-soluble emulsion for preventing flame propagation, protecting the heat insulating material and shielding harmful gas. When the amount is less than 50 parts by weight, the object of the present invention is difficult to achieve, flame retardancy is poor, and when it exceeds 100 parts by weight, the cost increases and product molding is affected.

상기 유리섬유는 컴파운드의 형태유지와 성형이 용이하게 하기 위하여 사용하며, 또한, 제품으로 제조되는 경우 균열을 방지하기 위하여 사용된다. 구체적으로 예를 들면, 길이가 0.1 ~ 30 m/m이며, 직경이 0.01 ~ 500 ㎛인 것을 사용하는 것이 제품의 균열 및 흘러내림 현상을 방지할 수 있으나, 반드시 이에 제한되는 것은 아니다.The glass fiber is used for easy maintenance and molding of the compound, and is used for preventing cracking when it is made into a product. Concretely, for example, the use of a material having a length of 0.1 to 30 m / m and a diameter of 0.01 to 500 탆 can prevent cracking and spilling of the product, but is not limited thereto.
