난연 및 단열성이 개선된 스티로폼{a highly flame resisting and heat insulating styrofoam}Styrofoam with improved flame retardancy and heat insulation properties {a highly flame resisting and heat insulating styrofoam}

본 발명은 고난연 고단열의 준불연성 스티로폼 제조방법 및 이에 의한 스티로폼에 관한 발명으로서, 특히 준불연성 효과가 큰 난연액을 사용하고 고단열 및 고난열을 특징으로 하는 발포 스티로폼 진공단열재 판재가 포함되는 준불연성 스티로폼 제조방법 및 이에 의한 스티로폼에 관한 것이다.The present invention relates to a method for manufacturing a highly flame-retardant high-insulation semi-non-combustible styrofoam and thereby styrofoam, in particular, a foamed styrofoam vacuum insulating material comprising high flame-retardant and high-heat-resistant flame retardants is used. It relates to a method for manufacturing a semi-incombustible styrofoam and thereby styrofoam.

일반적으로 건축물이나 전동차의 내장재로 사용되는 스티로폼은 내화성을 갖고 있지 않아서 건축물 또는 전동차에 화재가 발생하면 쉽게 전소되는 문제점이 있었다. 이러한 문제를 해결하기 위하여 여러 가지 기술개발이 시도되고 있다.Styrofoam, which is generally used as an interior material of buildings or electric vehicles, does not have fire resistance, and thus, when a fire occurs in buildings or electric vehicles, it is easily burned. Various technology developments have been attempted to solve these problems.

스티로폼(EPS, Expandable Polystyrene)은 다공성 재료로 단열 효과가 우수하며 가볍고 성형이 쉽기 때문에 단열재로 널리 사용되고 있다. 특히 스티로폼을 심재로 하고 그 양면에 철판을 덧댄, 일명 샌드위치 패널은 가볍고 단열효과가 우수하며, 빠른 시공이 가능한데다 저렴하기 때문에 건축자재로 널리 사용되고 있다. 또한 건물의 외벽에 스티로폼 단열재를 덧대어 마감하는 외단열미장마감공법(EIFS, Exterior Insulating and FinishingSystem), 일명 드라이비트(drivit) 공법은 시공이 쉽고 간편하여 공사기간을 단축할 수 있고 저렴하여 다가구주택이나 주상복합건물에 많이 사용되고 있다.Styrofoam (EPS, Expandable Polystyrene) is a porous material that is widely used as an insulating material because of its excellent insulating effect, light weight, and easy molding. In particular, Styrofoam is used as a core material, and it is widely used as a construction material because it is light and excellent in insulation effect, fast construction, and inexpensive. In addition, the exterior insulating and finishing system (EIFS), also known as the drivit method, which finishes with a styrofoam insulation on the outer wall of the building, is easy and simple to construct and can shorten the construction period and is cheap and multi-family housing It is often used in ina residential and commercial buildings.

그러나 스티로폼은 가연성 물질로서, 열에 매우 약하여 70℃가 넘으면 변형되며, 화재 발생시 많은 유독 가스를 발생시키고 구조가 붕괴되는 문제점을 갖고 있다. 특히 수직으로 설치된 스티로폼은 불쏘시개 역할을 하여 화염을 확산시킨다.However, styrofoam is a combustible material, and is very weak to heat, so it deforms when it exceeds 70℃, and generates a lot of toxic gases in the event of a fire and collapses its structure. In particular, the styrofoam installed vertically acts as a fire fighter and spreads the flame.

이에, 원료수지에 첨가되어 난연성을 나타낼 수 있는 난연제에 대한 연구가 활발히 진행되고 있다. 현재, 난연제로는 할로겐계가 가장 많고, 비할로겐계로는 인계와 질소계가 많이 사용되고 있다. 상기 할로겐계 난연제에서는 저렴하고 난연 효과가 높은 브롬화 난연제가 널리 사용되고 있으며, 스티로폼에 적용되는 브롬화 난연제로는HBCD(hexabromocyclododecane)가 가장 많이 쓰이고 있다.Accordingly, research into flame retardants that can be added to the raw material resin to exhibit flame retardancy is being actively conducted. Currently, most halogen-based flame retardants are used, and non-halogen-based phosphorus and nitrogen-based resins are used. In the halogen-based flame retardant, a brominated flame retardant that is inexpensive and has a high flame retardant effect is widely used, and as a brominated flame retardant applied to Styrofoam, hexabromocyclododecane (HBCD) is most frequently used.

대한민국 등록실용신안 제241745호의 스티로폼을 이용한 단열재에는 스티로폼의 양면에 알루미늄 시트와 염화비닐 사이에 유리섬유실사 또는 폴리에스터실사를 직조하여 접합시킨 불연소재를 부착시킨 스티로폼 단열재가 개시되어 있다.A styrofoam insulator in which a non-combustible material in which a glass fiber yarn or a polyester yarn yarn is woven and bonded between aluminum sheet and vinyl chloride on both sides of the styrofoam is woven is disclosed in the insulation using the styrofoam of the Republic of Korea Utility Model No. 241745.

또한 대한민국 등록실용신안 제196790호의 불연성 스치로폼 패널의 구조에는 스치로폼 패널의 정, 배, 좌, 우측 단면에 불연성층을 형성한 것을 개시하고 있다.In addition, the structure of the non-flammable styrofoam panel of the Republic of Korea Utility Model No. 196790 discloses that a non-combustible layer is formed on the right, rear, left and right sections of the styrofoam panel.

이들은 난연성을 더하기 위하여 스티로폼의 표면에 난연제를 코팅하거나, 불연소재를 양면 또는 육면에 부착하는 것은 단지 스티로폼의 표면에 난연제를 코팅하거나 부착하는 것이므로, 스티로폼 내부까지 난연도료가 침투하지 못하여, 패널을 재단하거나 표면이 손상되는 경우에는 화재에 그대로 노출되는 문제가 있다.In order to add flame retardancy, coating the flame retardant on the surface of the styrofoam or attaching the non-combustible material to both sides or the flesh surface is simply coating or attaching the flame retardant to the surface of the styrofoam, so the flame retardant paint cannot penetrate into the styrofoam, so the panel is cut. Or, if the surface is damaged, there is a problem of being exposed to the fire.

대한민국 공개특허 제2004-88786호의 조립식 패널 구조체용 폴리에스테르 난연심재 및 그 제조방법에는 난연제액을 폴리에스테르 견면에 침투시키고 롤러에 의하여 견면을 압축하여 침투시키고 타공롤러를 통하여 잉여난연제액을 빨아들인 후 마이크로웨이브장치로 건조시킨 후 히터를 이용하여 발포하여 제조하는 방법이 개시되어 있다. In the Republic of Korea Patent Publication No. 2004-88786 prefabricated panel structure for the polyester flame retardant core and its manufacturing method, the flame retardant liquid penetrates into the polyester hard cotton, and the roller is compressed by the hard cotton to infiltrate, and the surplus flame retardant liquid is sucked through the perforated roller. Disclosed is a method of manufacturing by drying using a microwave device and then foaming using a heater.

이는 난연제액이 침투된 후 발포작업을 수행하기 때문에 난연제가 소실되거나 화재시 난연도료 내부의 발포 알갱이가 녹아내리는 문제점이 있다.Since the foaming operation is performed after the flame retardant solution penetrates, there is a problem in that the flame retardant is lost or the foam particles inside the flame retardant paint are melted in case of fire.

대한민국 등록실용신안 제379868호의 난연성 스티로폼 단열재에는 각각의 발포 알갱이를 관통하여 연장되는 분사노즐에 의하여 통상의 난연도료를 분사 도포시키고 스티로폼 단열재 외부면 상에 통상의 단연도료를 도포하는 기술이 개시되어있다. 이는 스티로폼 내부에 직접 난연제를 주입시키는 것이므로 제조공정이 복잡하고, 분사노즐이 스티로폼 단열재를 관통하여 일정시간 일정압력으로 난연제액이 분사되므로 다수의 구멍이 생기게 되어 단열 효과가 떨어지게 되는 문제가 있다.In the Republic of Korea Utility Model No. 379868, the flame retardant styrofoam heat insulating material discloses a technique of spraying and applying a common flame retardant paint by spray nozzles extending through each foamed particle and applying a conventional insulating material on the outer surface of the styrofoam heat insulating material. . This is because the flame retardant is injected directly into the styrofoam, so the manufacturing process is complicated, and since the spray nozzle penetrates the styrofoam heat insulating material and the flame retardant liquid is sprayed at a constant pressure for a certain time, a number of holes are formed, and the heat insulation effect is deteriorated.

또한 공개특허 10-2016-0143137호(난연제 조성물, 난연성 스티로폼 및 그 제조방법)는 "세라믹 중공체; 및 20℃에서 점도가 5000 CP 이상 100000 CP 미만인 무기 바인더;를 포함하는 난연제 조성물 및 이를 이용한 난연성 스티로폼"을 제공한 바 있다.In addition, Patent Publication No. 10-2016-0143137 (flame retardant composition, flame retardant styrofoam, and a method for manufacturing the same) includes a “ceramic hollow body; and an inorganic binder having a viscosity of 5000 CP or more and less than 100000 CP at 20° C.; Styrofoam.

또한 공개특허 10-2005-0090628호(건축용 불연 단열보드)는 "공기층이 형성되고, 그 상·하 각각에 알루미늄 포일 및 알루미늄 펄이 피복되며, 알루미늄 펄의 밑에는 발포 폴리스티렌이 부착된 종래의 단열보드에 있어서, 상기 공기층을 카본섬유(131)와 실리카섬유(132)가 혼합되어 니들펀칭으로 결합된 부직포로 된 불연 단열층(130)과, 상기 불연 단열층(130) 상·하면 각각에 피복되어 불연 단열층(130)을 보호하며 방습작용을 하는 알루미늄 포일층(140)및 알루미늄 펄층(120)과, 상기 알루미늄 펄(120)층의 하단에 부착되어 미세기공으로 단열·방진·방음작용을 하는 단열층(110)으로 구성되는 것을 특징으로 하는 건축용 불연 단열보드"를 제공한 바 있다.In addition, Patent Publication No. 10-2005-0090628 (non-combustible insulation board for construction) "air layer is formed, aluminum foil and aluminum pearl are coated on each of the upper and lower, and under the aluminum pearl, conventional thermal insulation with foamed polystyrene attached In the board, the carbon layer 131 and the silica fiber 132 are mixed with a non-combustible insulating layer 130 made of a non-woven fabric bonded by needle punching, and the non-combustible insulating layer 130 is coated on each of the upper and lower surfaces to be non-combustible The aluminum foil layer 140 and the aluminum pearl layer 120 that protect the heat insulating layer 130 and perform moisture-proofing, and the heat insulating layer 110 that is attached to the bottom of the aluminum pearl 120 layer to insulate, dust, and sound with micro pores ) Has been provided."

It is a colorless, transparent thermoplastic material that becomes soft at 100°C or higher and becomes a viscous liquid when it reaches 185°C, and has strong properties such as acid, alkali, oil, and alcohol. Foamed polystyrene is a foamed product in which hydrocarbon gas such as pentane or butane is injected into this polystyrene resin and then inflated with steam.
