Description
본 발명은 난연 스티로폼 단열재에 관한 것으로서, 보다 상세하게는 스티로폼 단열재의 단열효율을 저해하지 않으면서도 화재 발생시 유독가스에 의한 인명피해와 화재 전파를 방지할 수 있는 난연 스티로폼 단열재에 관한 것이다.The present invention relates to a flame retardant styrofoam insulating material, and more particularly to a flame retardant styrofoam insulating material that can prevent human injury and fire propagation by toxic gas in the event of a fire without inhibiting the thermal insulation efficiency of the styrofoam insulating material.
일반적으로, 건축물의 벽체는 주로 콘크리트나 시멘트와 모래를 섞어 만든 벽돌 등으로 시공되며, 이러한 벽체에 단열재를 적층시킨 후, 다양한 마감재를 사용하여 실내의 벽체를 마감하게 된다.In general, the walls of the building is mainly constructed of concrete or cement and sand bricks, etc., after the insulation is laminated on these walls, various finishing materials are used to finish the walls of the room.
이러한 단열재 중 스티로폼(발포 폴리스티렌)은 그 사용의 편리성과 우수한 단열효과 및 저렴한 가격으로 인하여 가장 널리 사용되고 있는 재료이다. 그러나, 이러한 스티로폼은 열에 매우 약하여 화재 발생시 초기에 융해되어 화재를 전파시키는 매개체 역할을 할 뿐만 아니라, 연소시 발생하는 유독가스로 인하여 심각한 인명 피해를 일으키는 문제점이 있다.Among these insulation materials, styrofoam (foamed polystyrene) is the most widely used material due to its ease of use, excellent insulation effect and low price. However, such styrofoam is very weak to heat, so that it melts at the initial stage of the fire and serves as a medium for propagating the fire, and there is a problem of serious injury due to toxic gases generated during combustion.
이러한 문제점을 해결하기 위하여, 스티로폼의 난연성을 개선시켜 이들이 좀처럼 연소되지 않도록 하며 화염 전달이 더디도록 하는 다양한 방법들이 제안되었다. In order to solve this problem, various methods have been proposed to improve the flame retardancy of styrofoam so that they are rarely burned and the flame transmission is slow.
대한민국 특허 제10-305711호에는 발포 폴리스티렌 입자 표면에 할로겐화물, 인산화물 등의 난연제를 코팅하고 이를 발포성형하여 제조된 난연 스티로폼 단열재를 개시하고 있고, 대한민국 실용신안등록 제20-241745호에는 스티로폼 판재 양면에 알루미늄 시트, 직물 및 염화비닐의 3층구조로 이루어진 불연소재를 접착제로 부착한 난연 스티로폼 단열재를 개시하고 있다. 또한, 대한민국 공개특허 제2001-72979호에는 브롬화 유기 화합물로 이루어진 난연제를 첨가하는 방법이 개시되어 있다. 그러나, 이러한 난연 스티로폼 단열재들은 비경제적일 뿐만 아니라, 제조방법도 복잡하고 난연효과도 충분치 않다.Republic of Korea Patent No. 10-305711 discloses a flame-retardant styrofoam insulation prepared by coating a flame retardant such as halides, phosphates, etc. on the surface of the expanded polystyrene particles and foam molding, and the Republic of Korea Utility Model Registration No. 20-241745 is a styrofoam sheet Disclosed is a flame retardant styrofoam insulating material having a non-combustible material composed of a three-layer structure of aluminum sheet, fabric, and vinyl chloride on both sides with an adhesive. In addition, Korean Patent Laid-Open No. 2001-72979 discloses a method of adding a flame retardant made of a brominated organic compound. However, these flame retardant styrofoam insulation materials are not only economical, but also complicated in manufacturing method and insufficient flame retardant effect.
따라서, 본 발명이 이루고자 하는 기술적 과제는, 상기 문제점을 해결하여 스티로폼 단열재의 단열효율을 저해하지 않으면서도 화재 발생시 유독가스에 의한 인명피해와 화재 전파를 방지할 수 있는 경제적인 난연 스티로폼 단열재를 제공하는데 있다.Accordingly, the technical problem to be achieved by the present invention is to provide an economical flame retardant styrofoam insulating material that can solve the above problems and prevent human injury and fire propagation due to toxic gases in the event of fire without impairing the thermal insulation efficiency of the styrofoam insulating material. have.
상기 기술적 과제를 달성하기 위하여, 본 발명은 발포 폴리스티렌계 입자와 다공성 광물 입자를 1000:1 ~ 1000:800의 부피비로 혼합하여 압축성형한 것을 특징으로 하는 난연 스티로폼 단열재를 제공한다.In order to achieve the above technical problem, the present invention provides a flame retardant styrofoam insulating material characterized in that the compression-molded by mixing the expanded polystyrene-based particles and porous mineral particles in a volume ratio of 1000: 1 to 1000: 800.
본 발명에 따른 난연 스티로폼 단열재에 있어서, 다공성 광물 입자로는 제올라이트(zeolite), 벤토나이트(bentonite), 펄라이트(pearlite), 일라이트(illite) 등을 단독으로 또는 이들을 혼합하여 사용할 수 있으며, 다공성 광물 입자의 평균입경은 80 내지 200메쉬인 것이 바람직하다.In the flame retardant styrofoam insulating material according to the present invention, as the porous mineral particles, zeolite, bentonite, pearlite, illite, and the like may be used alone or in combination thereof. It is preferable that the average particle diameter of is 80-200 mesh.
이하, 본 발명에 따른 난연 스티로폼 단열재에 대하여 상세히 설명한다.Hereinafter, the flame-retardant styrofoam insulating material according to the present invention will be described in detail.
전술한 바와 같이, 스티로폼으로 이루어진 단열재는 그 사용의 편리성과 우수한 단열효과 및 저렴한 가격으로 인하여 가장 널리 사용되고 있는 단열재이나, 열에 매우 약하여 화재 발생시 초기에 융해되어 화재를 전파시키는 매개체 역할을 할 뿐만 아니라, 연소시 발생하는 유독가스로 인하여 심각한 인명 피해를 일으킨다. 본 발명자는 제올라이트(zeolite), 벤토나이트(bentonite), 펄라이트(pearlite), 일라이트(illite) 등과 같이 그 표면 및 내부에 많은 기공을 갖는 다공성 광물 입자를 발포 폴리스티렌 입자와 혼합하고 압축성형하여 스티로폼 단열재를 제조한 결과, 화재 발생시 스티로폼 단열재 내부에 혼합된 다공성 광물 입자가 스티로폼 연소에 의해 발생하는 유독가스를 흡수하여 유독가스 배출량을 현격히 줄이며, 또한 열에 의해 녹아 흐르는 스티로폼 융해액을 다공성 광물 입자가 흡수하여 스티로폼 융해액에 의한 화재 전파를 차단한다는 사실을 발견하여 본 발명을 완성하게 되었다.As described above, the insulation material made of styrofoam is the most widely used insulation material due to its ease of use, excellent insulation effect and low price, but it is very weak to heat, so it melts at the early stage of fire and serves as a medium for propagating fire. Toxic gases generated during combustion cause serious personal injury. The present inventors mixed a porous mineral particle having many pores on its surface and inside with zeolite, bentonite, pearlite, illite and the like with foamed polystyrene particles and compression molded to form a styrofoam insulating material. As a result, the porous mineral particles mixed inside the styrofoam insulation material absorb the toxic gas generated by styrofoam combustion in the event of fire, and the toxic gas emissions are greatly reduced, and the porous mineral particles absorb the styrofoam melt flowing by melting with styrofoam. The present invention has been completed by discovering that the fire propagation by the melt is blocked.
따라서, 본 발명에 사용되는 다공성 광물 입자는 화산 쇄설물의 속성작용을 받아 생성되는 제올라이트(zeolite) 및 벤토나이트(bentonite)나, 펄라이트(pearlite), 일라이트(illite) 등 그 표면 및 내부에 다수의 기공이 형성되어 스티로폼 연소에 의해 발생하는 유독가스나 그 융해액을 흡수할 수 있는 것이라면 사용 가능하다. 이러한 다공성 광물 입자는 그 내부의 기공으로 인하여 스티로폼 단열재 특유의 단열효과를 저해하지 않는다.Therefore, the porous mineral particles used in the present invention are a plurality of pores on the surface and the inside, such as zeolite and bentonite, pearlite, illite, etc., produced by the action of volcanic debris. This can be used as long as it is formed and can absorb toxic gases generated by styrofoam combustion and its melt. These porous mineral particles do not inhibit the thermal insulation effect peculiar to the styrofoam insulation due to the pores therein.
본 발명의 난연 스티로폼 단열재 형성시, 다공성 광물 입자와 발포 폴리스티렌계 입자는 본 발명이 목적하는 효과와 단열재의 중량 및 제조비용을 고려할 때 1000:1 ~ 1000:800의 부피비로 혼합하는 것이 바람직하며 특히, 1000:10 ~ 1000:100의 부피비로 혼합하는 것이 더욱 바람직하다. 또한, 본 발명에 사용되는 다공성 광물 입자의 평균입경은 발포 폴리스티렌 입자와의 혼합 분산성과 난연 효율을 고려할 때, 특히 80 내지 200메쉬인 것을 사용하는 것이 바람직하다. In forming the flame retardant styrofoam insulation of the present invention, the porous mineral particles and the expanded polystyrene-based particles are preferably mixed at a volume ratio of 1000: 1 to 1000: 800 in consideration of the desired effect of the present invention and the weight and manufacturing cost of the insulation. More preferably in a volume ratio of 1000: 10 to 1000: 100. In addition, the average particle diameter of the porous mineral particles used in the present invention is preferably 80 to 200 mesh, especially considering the mixing dispersibility and flame retardant efficiency with the expanded polystyrene particles.
본 발명에 따른 난연 스티로폼 단열재의 제조방법을 살펴보면 다음과 같다.Looking at the manufacturing method of the flame-retardant styrofoam insulating material according to the present invention.
발포 폴리스티렌계 입자는 당업자에게는 용이하게 구입하여 사용할 수 있을 정도로 상용화되어 있는데, 범용수지의 일종인 폴리스티렌계 수지에 에탄, 프로판, 부탄, 펜탄, 헥산, 옥탄 등과 같은 저비점 탄화수소를 함침시키고 발포시켜 낮은 밀도에 의한 경량화와 발포에 의한 용적증가에 따른 단열효과 및 완충효과 등을 얻을 수 있는 발포체로 이해될 수 있다. 발포 폴리스티렌계 입자의 평균입경은 목적하는 단열재의 형상과 물성에 따라 다양하게 변화시킬 수 있는데, 2000 내지 6000메쉬 정도의 입자를 사용하는 것이 바람직하다. 폴리스티렌계 수지로는 당업자에게 알려진 다양한 종류의 폴리스티렌계 수지, 예를 들어 폴리스티렌 수지뿐만 아니라 스티렌과 부타디엔의 블록 공중합 수지나 이들과 폴리스티렌계 수지의 블랜드, 내충격성 폴리스티렌 수지(HIPS) 등과 같은 각종 개질 폴리스티렌계 수지를 사용할 수 있다(대한민국 공개특허공보 제2000-57292 참조). 제올라이트(zeolite), 벤토나이트(bentonite) 등의 다공성 광물 또한 입자 크기 별로 쉽게 구입할 수 있다.The expanded polystyrene-based particles are commercially available to those skilled in the art and can be easily purchased and used. A low density is obtained by impregnating and foaming low-boiling hydrocarbons such as ethane, propane, butane, pentane, hexane, and octane in a polystyrene resin, which is a kind of general purpose resin. It can be understood as a foam that can be obtained by the weight reduction and foam insulation by the increase in volume due to foaming and the like. The average particle diameter of the expanded polystyrene-based particles can be changed in various ways depending on the shape and physical properties of the desired heat insulating material, it is preferable to use particles of about 2000 to 6000 mesh. Polystyrene resins include various types of polystyrene resins known to those skilled in the art, for example, polystyrene resins, as well as various copolymers of styrene and butadiene, blends of these and polystyrene resins, and various modified polystyrene resins such as impact resistant polystyrene resins (HIPS). System resin can be used (refer Korean Unexamined-Japanese-Patent No. 2000-57292). Porous minerals such as zeolite and bentonite are also readily available by particle size.
이렇게 구입한(필요에 따라 제조한) 발포 폴리스티렌계 입자와 다공성 광물 입자를 소정 비율로 혼합한 후, 소정의 틀에 넣고 압축성형하면 원하는 형상과 두께를 가진 난연 스티로폼 단열재를 생산할 수 있다.When the thus-expanded (produced as needed) foamed polystyrene-based particles and porous mineral particles are mixed in a predetermined ratio, and then put into a predetermined mold and compression molded, a flame retardant styrofoam insulating material having a desired shape and thickness can be produced.
이하, 본 발명을 구체적으로 설명하기 위해 실시예를 들어 상세하게 설명하기로 한다. 그러나, 본 발명에 따른 실시예들은 여러 가지 다른 형태로 변형될 수 있으며, 본 발명의 범위가 아래에서 상술하는 실시예들에 한정되는 것으로 해석되어져서는 안된다. 본 발명의 실시예들은 당업계에서 평균적인 지식을 가진 자에게 본 발명을 보다 완전하게 설명하기 위해서 제공되어지는 것이다.Hereinafter, the present invention will be described in detail with reference to Examples. However, embodiments according to the present invention can be modified in many different forms, the scope of the present invention should not be construed as limited to the embodiments described below. Embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.
실시예Example
평균입경이 3000 ~ 4000 메쉬인 발포 폴리스티렌 입자와 평균입경이 80 ~ 100 메쉬인 제올라이트 입자를 1000 : 50의 부피비로 균일하게 혼합한 후, 틀에 넣고 압축성형하여 도 1에 도시된 난연 스티로폼 단열재를 제조하였다.After mixing uniformly mixing the expanded polystyrene particles having an average particle diameter of 3000 to 4000 mesh and the zeolite particles having an average particle size of 80 to 100 mesh in a volume ratio of 1000: 50, and put them in a mold and compression molding to obtain a flame-retardant styrofoam insulating material shown in FIG. Prepared.
비교예Comparative example
제올라이트 입자를 첨가하지 않은 것을 제외하고는 실시예와 동일한 방법으로 스티로폼 단열재를 제조하였다.Styrofoam insulation was prepared in the same manner as in Example, except that zeolite particles were not added.
토치를 이용하여 상기 실시예 및 비교예에 따라 제조한 단열재 하부에 불꽃을 접촉시켰다. 종래의 스티로폼 단열재(비교예)는 다량의 유독가스를 발생시키며 발포 폴리스티렌 입자의 융해액이 흘러내리는 반면에, 본 발명에 따른 난연 스티로폼 단열재(실시예)는 소량의 유독가스만 발생시켰고, 또한 발포 폴리스티렌 입자의 융해액이 흘러내리지 않았으며 다공성 광물 입자 자체가 떨어졌다. 이는 발포 폴리스티렌 입자(2)의 융해액을 인접한 다공성 광물 입자(1)가 기공을 통하여 흡수한 결과로서, 화재 전파성을 현저히 감소시킴을 알 수 있다.The flame was brought into contact with the lower portion of the insulation prepared according to the above Examples and Comparative Examples using a torch. The conventional styrofoam insulation material (comparative example) generates a large amount of toxic gas and the melt of the expanded polystyrene particles flows down, whereas the flame-retardant styrofoam insulation material (example) according to the present invention generated only a small amount of toxic gas, and also foamed The melt of polystyrene particles did not flow down and the porous mineral particles themselves fell. This can be seen that as a result of absorbing the melt of the expanded polystyrene particles (2) through the pores of adjacent porous mineral particles (1), it significantly reduces the fire propagation.
이상에서 설명한 바와 같이, 본 발명에 따른 난연 스티로폼 단열재는 스티로폼 단열재의 단열효율을 저해하지 않으면서도 화재 발생시 스티로폼의 연소에 의해 발생하는 유독가스와 열에 의해 녹아 흐르는 스티로폼 융해액을 다공성 광물 입자가 흡수하여 유독가스에 의한 인명피해, 스티로폼 융해액에 의한 화재 전파 및 융해액 접촉에 따른 화상을 방지할 수 있다.As described above, the flame-retardant styrofoam insulating material according to the present invention absorbs the styrofoam melt melted by the toxic gas and heat generated by the combustion of the styrofoam in the event of a fire, without impairing the thermal insulation efficiency of the styrofoam insulating material by the porous mineral particles It is possible to prevent human injury due to toxic gas, fire propagation by styrofoam melt and burns due to contact with melt.
