불연성제가 코팅된 스치로폼 및 그 제조방법{STYROTOAM COATED NONCOMBUSTIBLE AGENT AND ITS MANUTALTURING METHOD}Styrofoam coated with incombustibles and its manufacturing method {STYROTOAM COATED NONCOMBUSTIBLE AGENT AND ITS MANUTALTURING METHOD}

본 발명은 건축용 스치로폼의 표면에 불연성 코팅제를 도포하여 연소속도가 지연되고 유독가스의 발생이 최소화되게 하므로서 화재발생시 인명피해가 방지되도록 한 불연성제가 코팅된 스치로폼 및 그 제조방법에 관한 것이다.The present invention relates to a styrofoam coated with a non-flammable agent and to a method of manufacturing the same by applying a non-flammable coating agent on the surface of the building styrofoam to minimize the generation of toxic gases and to delay combustion speed.

일반적으로, 건축단열재로서 널리 사용되는 스치로폼은 가연성물질로서 화재발생시 급속한 발화가 이루어짐은 물론 다량의 유독가스가 발생되므로 대형사고의 직접적 원인이 되었다.In general, styrofoam, widely used as a building insulation material, is a combustible material, which causes rapid ignition in the event of a fire and generates a large amount of toxic gas.

근래에는 화재발생시에 대형사고를 방지하기 위하여 여러종류의 불연성 또는 난연성 내장재가 개발되고 있는 실정이다.Recently, various kinds of non-combustible or flame retardant interior materials have been developed to prevent large accidents in case of fire.

종래에 개발된 불연성 내장재를 살펴보면 다음과 같다.Looking at the non-combustible interior materials developed in the prior art as follows.

국내특허공개 제99-84110호의 "불연성 건축자재의 제조방법"은 "소다장석과 점토를 일정비율로 배합하여 고상의 혼합물을 만드는 단계; 볼밀에 주석과 상기 고상의 혼합물을 투여하고 물을 부어 1시간동안에 걸쳐서 충분히 혼합하여 슬립을 얻는 단계; 상기 볼밀로부터 상기 슬립을 강제로 배출시키고 파이프라인을 따라서 상기 볼밀 근처에 설치된 슬립탱크내로 이송한후 상기 슬립탱크내에서 균일하게 교반하면서 보관하는 단계; 상기 슬립과는 별도로 주원료인 질석 또는 운모류를 정량공급기내에 장입하는 단계; 상기 슬립탱크로부터 혼련기내로 상기 슬립을 도입하고 상기 정량공급기로부터 상기 혼련기내로 질석 또는 운모류를 도입한후 상기 혼련기내에서 상기 슬립과 상기 질석 또는 상기 운모류를 충분히 혼합하여 진공처리하는 단계; 상기 혼련기에서 혼합된 혼합물을 성형기로 이송하여 성형하는 단계; 상기 성형기에서 성형된 제품을 일정길이로 절단한후 80∼120% 건조열풍을 이용하여 건조시키는 단계; 건조된 제품을 로내에서 850∼1100℃의 온도로 18시간동안 소성시키는 단계; 그리고 소성된 제품을 검사한후 포장하여 출하하는 단계를 순차적으로 실행하면서 불연성 건축자재를 제조하는 것이다.Korean Patent Publication No. 99-84110, "Method of manufacturing non-combustible building materials", "Synthesis and mixing clay in a proportion to make a solid mixture; administering a mixture of tin and the solid phase to a ball mill and pour water 1 Mixing sufficiently over time to obtain a slip, forcibly discharging the slip from the ball mill and transferring it along a pipeline into a slip tank installed near the ball mill and storing it in the slip tank with uniform stirring; Charging the vermiculite or mica, which is a main material separately from the slip, into the quantitative feeder, introducing the slip from the slip tank into the kneader and introducing the vermiculite or mica from the quantitative feeder into the kneader and then slipping the slip in the kneader. Sufficiently mixing and evacuating the vermiculite or the mica; Transporting the mixed mixture in the molding machine to a molding machine, cutting the molded product to a predetermined length, and drying the same by using 80-120% dry hot air; drying the dried product in a furnace at 850-1100 ° C. Firing at a temperature of 18 hours, and then inspecting the fired product and packaging and shipping the same to sequentially manufacture non-combustible building materials.

그러나, 이러한 선발명은 불연성 건축자재를 제조하기 위하여 여러공정을 거쳐야되므로 제조원가가 상승되는 원인이 된다. 더욱이 상기 선발명으로 제조된 제품은 단열재의 용도로 사용되는 것으로서, 건축내장재의 모든 제품에 적용할 수 없으므로, 결국 모든 내장재를 개별적인 방법으로 제조하여야 되었다. 그리고 기존에 설치된 건축물의 경우에 가연성 내장재를 폐기한후 불연성 내장재를 교체하여야 되기 때문에 비경제적일 뿐 아니라, 비용의 부담으로 인하여 화재위험으로부터 그대로 방치되고 있는 실정이었다.However, this selection has to go through several processes in order to manufacture the non-combustible building materials, causing a rise in manufacturing costs. Furthermore, the products manufactured by the above-described invention are used for the insulation, and thus cannot be applied to all the products of the building interior materials, and thus, all interior materials have to be manufactured in a separate method. In addition, in the case of the existing building, since it is necessary to replace the non-combustible interior materials after discarding the combustible interior materials, it is not only uneconomical but also left unattended from the risk of fire due to the burden of cost.

또한, 국내특허공개 제98-9174호의 "불연성 건축물 내외장용 보-드 및 그것의 제조방법"은 "활성백토에 미세한 톱밥이나 수수대속 분말 및 착색제 소량을 황산칼슘, 규산칼슘, 마그네슘 또는 염화마그네슘 등이 함유된 간수나 그 간수와 동일성분의 조성물질과 혼합하여 페이스트상 혼합물로 한 다음 연속진행되는 유리판, 아클리판, 폴리카보네이트판, 폴리비닐 클로라이드판 또는 폴리프로 필렌판 상에 글라스 화이버가 상기 페이스트상 혼합물층 상하에 합착적층되게 공급하면서 샌드위치 롤러에 통과시켜 일정두께로 압착하여 소정의 혼합물 시트를 얻은 다음 그 표면을 에폭시 수지층으로 평활하게 한후 그 위에 접착제층, 전사필름층, 자외선 경화수지층 및 보호필름층을 차례로 적층하여 불연성보드를 제조하는 것이다.In addition, Korean Patent Publication No. 98-9174, "Board for interior and exterior decoration of non-combustible buildings and its manufacturing method", "Sawdust or sorghum powder and a small amount of coloring agent in activated clay, calcium sulfate, calcium silicate, magnesium or magnesium chloride, etc. The mixed water or the mixed water with the composition of the same ingredient to form a paste mixture, and then the glass fibers on the continuous glass plate, aclipan, polycarbonate plate, polyvinyl chloride plate or polypropylene plate After passing through the sandwich roller while pressing the paste mixture layer up and down, they are compressed to a certain thickness to obtain a predetermined mixture sheet. The surface is then smoothed with an epoxy resin layer, and then the adhesive layer, transfer film layer, and UV curable water are placed thereon. The laminated layer and the protective film layer are sequentially laminated to manufacture a nonflammable board.

그러나, 이러한 선발명 역시 내외장용 보드의 특정제품에 적용되는 것으로 그 사용범위가 한정되어 있을 뿐 아니라, 제품을 제조하기 위한 공정이 복잡하므로 원가가 상승되어 사용이 기피되고 있는 실정이었다.However, this selection is also applied to a specific product of the interior and exterior boards, the use of the product is not only limited, and the manufacturing process of the product is complicated, so that the cost is increased and the use is avoided.

또한, 국내특허공개 제96-4463호의 "불연성방화 도포조성물"이 있으며, 이러한 선발명은 열에 의하여 발포팽창하는 성질을 가지는 규산나트륨, 백색안료인 산화티탄, 발포되었을 때 피막을 단단하게 하여 발포막을 보호하여주는 폴리에틸렌디아민, 물이 적당량 혼합되어 구성된 것이다.In addition, there is a "non-flammable fire-retardant coating composition" of Korean Patent Publication No. 96-4463, this selection is sodium silicate having a property of expansion and expansion by heat, titanium oxide as a white pigment, when foamed to protect the foam film by hardening the film It is composed of a suitable amount of polyethylene diamine and water mixed.

그러나, 이러한 선발명은 가연성 물질의 연소속도를 지연시키는 효과는 있으나, 유독가스의 발생을 억제할 수 없으므로, 화재발생 초기에 유독가스에 의한 인명피해를 방지할 수 없었다.However, this selection has the effect of delaying the combustion rate of the combustible material, but it is not possible to suppress the generation of toxic gas, and thus, it is not possible to prevent the human injury caused by the toxic gas at the beginning of the fire.

본 발명은 상기한 문제를 해결하기 위하여 연구개발된 것으로서, 건축용으로 사용되는 스치로폼의 표면에 불연성제를 코팅하므로서 간단하게 제조할 수 있도록 하는데 그 기술적 과제가 있다.The present invention has been researched and developed in order to solve the above problems, there is a technical problem to be able to simply manufacture by coating a non-flammable agent on the surface of the styrofoam used for construction.

본 발명의 다른 기술적 과제는 기존의 가연성 스치로폼 설치된 상태에서 표면에 불연성제를 도포하면 기존의 스치로폼을 폐기하지 않고도 화재로부터 인명 및 경제적 손실을 방지할 수 있도록 하는데 있다.Another technical problem of the present invention is to apply a nonflammable agent to a surface in a state where an existing flammable styrofoam is installed so as to prevent human and economic loss from fire without discarding the existing styrofoam.

본 발명의 또다른 기술적 과제는 화재발생시에 스치로폼의 연소속도가 지연될 뿐 아니라, 유독성가스의 발생이 최소로 되므로 인명피해를 최소로하면서 초기에 화재진압을 할 수 있도록 하는데 있다.Another technical problem of the present invention is not only to delay the combustion speed of the styrofoam during the fire, but also to minimize the generation of toxic gas, so that it is possible to suppress the initial fire while minimizing the casualties.

본 발명은 화재시 발화가 지연되고 유해가스의 발생을 억제시키기 위하여, 작은입자로 분쇄된 불연성제를 액상의 혼합용제에 혼합한후 스치로폼의 표면에 코팅하여서 제조하는 것이다.The present invention is prepared by coating the surface of the styrofoam after mixing the incombustibles pulverized into small particles in a liquid mixed solvent in order to delay the ignition in the fire and to suppress the generation of harmful gases.

상기 불연성제는 전체 중량비로서 산화규소(SiO2) 70∼80%, 산화알미늄(Al2O3) 10∼15%, 산화철(Fe2O3) 3∼5%, 산화칼슘(CaO) 2∼4%, 산화마그네슘(MgO) 2∼4%, 산화나트륨(Na2O) 3∼5%로 조성한다.The nonflammable agent is 70 to 80% of silicon oxide (SiO 2 ), 10 to 15% of aluminum oxide (Al 2 O 3 ), 3 to 5% of iron oxide (Fe 2 O 3 ), and calcium oxide (CaO) 2 to 4%, magnesium oxide (MgO) 2 to 4%, sodium oxide (Na 2 O) 3 to 5%.

상기 산화규소는 자연상태에 많이 존재하는 것으로 실리카 또는 규산이라고 명하기도하는 것으로서, 다결정재료이며 여러종류의 결정구조를 가질 수 있다. 또한 내열성과 단열성이 크므로 내화재료에 널리 이용된다.The silicon oxide, which is often present in nature, is also called silica or silicic acid, and is a polycrystalline material and may have various types of crystal structures. In addition, it is widely used in refractory materials because of its high heat resistance and heat insulation.

상기 산화알루미늄은 자연상태에 많이 존재하는 것으로 철, 산소, 규소같은 다른 원소들과 결합된 상태로 존재한다. 베이어(Bayer) 법에서 보오크사이트를 뜨거운 수산화나트륨과 반응시키면 광석중의 알루미늄이 알루민산나트륨으로 되며 비용해물질의 제거후에 알루민산 용액으로부터 알루미늄의 수산화물이 석출된다. 그후 알루미늄 수산화물을 농축시키고 칼시닝(calcining)하여 산화알루미늄을 제조하는 것으로서, 표면에 산화물 피막을 형성하여 주기 때문에 우수한 내식성을 지니고 있고 무독성이다.The aluminum oxide is present in a lot of natural state and exists in a state of being combined with other elements such as iron, oxygen, and silicon. When bauxite is reacted with hot sodium hydroxide in the Bayer method, aluminum in the ore becomes sodium aluminate, and aluminum hydroxide is precipitated from the aluminate solution after removal of the insoluble substances. After that, the aluminum hydroxide is concentrated and calcined (calcining) to produce aluminum oxide, because it forms an oxide film on the surface has excellent corrosion resistance and non-toxic.

상기 산화철과 산화마그네슘과 산화나트륨은 각각 내열성이 양호하다.The iron oxide, magnesium oxide, and sodium oxide have good heat resistance, respectively.

상기 불연성재료는 입자의 크기, 즉 입도 250∼400메쉬의 미세입자로 분쇄한후, 혼합용제에 혼합하는 것이다.The non-combustible material is pulverized into fine particles having a particle size, that is, a particle size of 250 to 400 mesh, and then mixed in a mixed solvent.

상기 혼합용제는 전분등의 식물성 접착제가 첨가된 수용액이나 접착성수지가 첨가된 수용액등 필요한 것을 선택적으로 사용할 수 있다.The mixed solvent may optionally be used, such as an aqueous solution to which a vegetable adhesive such as starch is added or an aqueous solution to which an adhesive resin is added.

상기 불연성제는 혼합용제에 혼합된 상태로 가연성인 스치로폼 표면에 0.05∼0.8mm의 두께로 도포하는 것으로서, 도포된후 건조시키면 불연성제가 고체화된 상태로 코팅되는 것이다.The nonflammable agent is applied to the surface of the combustible Styrofoam in a mixed state in a mixed solvent in a thickness of 0.05 to 0.8 mm, and when applied and dried, the nonflammable agent is coated in a solid state.

이러한, 불연성제가 코팅된 스치로폼은 화재발생시 자체의 가연성 물질에 의하여 발화되면, 불연성제에 의하여 발화가 지연되고 유독가스의 발생이 최소로되는 것이다. 즉, 열기가 스치로폼에 가해지면, 표면에 코팅된 불연성제에 의하여 일차 연소가 지연될 뿐 아니라, 고체화되어 있던 불연성제가 분말화되면서 가연성 물질인 스치로폼에 흡착되므로 산소의 공급을 차단시키며, 또한 불연성제가 연소되면서 다공정의 흡착력이 큰 분말로 변환되므로 스치로폼이 연소되면서 발생되는 유독가스가 분말화된 불연성제로 흡착되어 외부로 방출되는 것이 방지된다.When the non-flammable agent coated Styrofoam is ignited by its combustible material at the time of fire, the ignition is delayed by the non-flammable agent and the generation of toxic gas is minimized. That is, when heat is applied to the styrofoam, not only the primary combustion is delayed by the non-flammable agent coated on the surface, but also the solidified non-flammable agent is powdered and adsorbed to the styrofoam, which is a combustible material, to block the supply of oxygen, and As it is combusted, the adsorption power of the multi-process is converted into a powder, so that the toxic gas generated when the styrofoam is combusted is adsorbed by the powdered nonflammable agent and is prevented from being released to the outside.

이하, 본 발명을 제조공정에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail by the manufacturing process as follows.

불연성제의 제조공정Nonflammable Manufacturing Process

산화규소(SiO2), 산화알미늄(Al2O3), 산화철(Fe2O3), 산화칼슘(CaO), 산화마그네슘(MgO), 산화나트륨(Na2O)을 각각 파쇄기에서 분쇄한후, 망체에 의하여 미립자를 분리한다. 상기 미립자의 입도는 250∼450메쉬가 바람직하다.After grinding silicon oxide (SiO 2 ), aluminum oxide (Al 2 O 3 ), iron oxide (Fe 2 O 3 ), calcium oxide (CaO), magnesium oxide (MgO) and sodium oxide (Na 2 O) in the shredder The fine particles are separated by the net. The particle size of the fine particles is preferably 250 to 450 mesh.

상기에서 미세한 입자로 분쇄된 각각의 재료를 전체 중량비로서, 산화규소 70∼80%, 산화알미늄 10∼15%, 산화철 3∼5%, 산화칼슘 2∼4%, 산화마그네슘 2∼4%, 산화나트륨 3∼5%를 믹서기에 투입하고 혼합하여서 불연성제를 제조한다.Each material pulverized into fine particles is 70 to 80% of silicon oxide, 10 to 15% of aluminum oxide, 3 to 5% of iron oxide, 2 to 4% of calcium oxide, 2 to 4% of magnesium oxide, and oxidation 3 to 5% of sodium is added to a blender and mixed to prepare a nonflammable agent.

상기 산화규소는 그 혼합량이 70% 미만이되면, 내열성이 저하되고 80%를 초과하게 되면 혼합용제와 혼합한후 스치로폼에 코팅할때에 접착력이 저하되므로 전체 중량에 대한 혼합량을 70∼80%하는 것이 바람직하다.When the silicon oxide is less than 70% of the mixture, the heat resistance is lowered, if it exceeds 80%, the adhesive strength is reduced when mixing with the mixed solvent and then coated on the styrofoam 70 to 80% to the total weight It is preferable.

상기 산화알미늄은 그 혼합량이 10%미만이 되면, 그 효능이 저하되고 15%를 초과하게되면 다른 재료, 즉 산화규소의 혼합량이 저하되므로 전체중량에 대한 혼합량을 10∼15%로 하는 것이 바람직하다.When the amount of the aluminum oxide is less than 10%, the efficiency thereof is lowered, and when the amount exceeds 15%, the amount of mixing of other materials, that is, silicon oxide, is lowered. .

상기 산화철과 산화칼슘과 산화마그네슘과 산화나트륨은 필요에 따라 혼합하거나 제외시킬 수 있으며, 산화규소와 산화알미늄을 얻기 위하여 자연상태의 광석을 제련하는 과정중에 포함될 수 있다.The iron oxide, calcium oxide, magnesium oxide and sodium oxide may be mixed or excluded as necessary, and may be included in the process of smelting natural ore in order to obtain silicon oxide and aluminum oxide.

코팅제의 제조공정Coating Process

상기 공정에서 제조된 불연성재료를 혼합용제에 첨가하여 코팅제를 제조한다.The non-combustible material prepared in the above process is added to the mixed solvent to prepare a coating agent.

상기 혼합용제는 접착성분을 갖고 있는 식물성 전분등을 물에 용해시키거나 접착성수지를 물에 용해시켜 제조한다.The mixed solvent is prepared by dissolving a vegetable starch having an adhesive component in water or dissolving an adhesive resin in water.

본 발명은 상기 혼합용제의 성분에 구애를 받지 않으며, 기존에 알려진 것 중에서 선택적으로 사용할 수 있으나, 다음과 같은 조건이 필요하다.The present invention is not limited to the components of the mixed solvent, and may be selectively used from the known ones, but the following conditions are required.

혼합용제의 조건은, 첫째; 스치로폼과 친화력이 좋을 것, 둘째; 불연성일 것, 셋째; 가열시 유해가스의 발생이 없거나 극히 적을 것, 넷째; 투명한 무색 또는 백색일 것 등을 필요로 한다.The conditions of the mixed solvent are first; Good affinity with styrofoam, second; To be nonflammable, third; No or minimal generation of harmful gases upon heating; fourth; Transparent or colorless or white.

상기 불연성제를 혼합용제에 첨가하여 혼합하므로서 액상의 코팅제를 제조하는 것으로서, 불연성제의 혼합비율을 전체 중량비로서, 25∼45%로 하고 혼합용제의 혼합비율을 전체 중량비로서 15∼70%로 한다.A liquid coating agent is prepared by adding and mixing the non-flammable agent to the mixed solvent. The mixing ratio of the non-flammable agent is 25 to 45% as the total weight ratio, and the mixing ratio of the mixed solvent is 15 to 70% as the total weight ratio. .

불연성제의 혼합비율이 25% 미만이 되면, 건조시간이 지연되고 필요한 코팅두께를 얻을 수 없으며, 45%를 초과하게 되면, 유동성이 저하되어 코팅작업시 골고루 도포되지 않는 등 어려움이 있으므로, 불연성제를 코팅액의 전체 중량비로서 25∼45%를 첨가하는 것이 바람직하다.If the mixing ratio of the nonflammable agent is less than 25%, the drying time is delayed and the required coating thickness cannot be obtained. If the nonflammable agent is more than 45%, the fluidity is lowered, so that the coating is not evenly applied during the coating operation. It is preferable to add 25 to 45% as the total weight ratio of the coating liquid.

코팅공정Coating process

상기 공정에서 제조된 코팅제를을 스치로폼의 표면에 고착시키는 것이다.The coating prepared in the above process is to adhere to the surface of the styrofoam.

먼저, 스치로폼의 표면에 상기 코팅제를 도포하며, 이러한 도포방법은 붓에 의하여 직접 칠하거나, 공기압에 의하여 분사하거나, 소재를 코팅액에 담근후 인출하는 방법중에서 선택적으로 사용할 수 있다.First, the coating agent is applied to the surface of the styrofoam, and such a coating method may be selectively used in a method of applying directly by a brush, spraying by air pressure, or immersing a material in a coating liquid and then drawing it out.

코팅제가 도포된 건축내장재는 열풍건조방식에 의하여 코팅제에 함유된 수분을 제거하는 것으로서, 건조로에 투입한후 60∼80℃의 조건에서 2∼6시간동안 건조시켜 수분이 제거되어 불연성제가 건축내장재의 외면에 코팅층으로 적층형성된다.Building interior material coated with coating removes moisture contained in coating material by hot air drying method, and it is put into drying furnace and dried for 2 ~ 6 hours under the condition of 60 ~ 80 ℃ to remove moisture. The outer surface is laminated with a coating layer.

상기 코팅층의 두께는 0.05∼0.80mm가 바람직하며, 원하는 두께를 얻기 위하여 코팅제의 도포와 건조를 반복적으로 실행할 수 있다. 즉, 일차 코팅제의 도포시 코팅두께가 0.2∼0.4mm 정도이므로 건조후 고착시킨 상태에서 재차 코팅제를 도포하는 방법으로 비교적 두꺼운 두께의 코팅층을 제조할 수 있다.The thickness of the coating layer is preferably 0.05 to 0.80 mm, and can be repeatedly applied and dried to obtain the desired thickness. That is, since the coating thickness is about 0.2 to 0.4 mm when the primary coating agent is applied, a coating layer having a relatively thick thickness may be manufactured by applying the coating agent again in a fixed state after drying.

상기 코팅층의 두께는 0.2mm미만이 되면, 화재발생시 유해가스의 흡착력이 적어 불연성제의 역할을 기대할 수 없으며, 코팅층의 두께가 클수록 화재시 발화를 지연시키고 유해가스의 흡착력이 큰 효과가 있으나, 코팅층에 균열이 발생되어 외관이 좋지 못하므로 0.8mm를 초과하지 않는 것이 바람직하다.If the thickness of the coating layer is less than 0.2mm, the adsorption power of the harmful gas is not expected when the fire occurs, the role of the non-flammable agent can not be expected, the greater the thickness of the coating layer has the effect of delaying the ignition in the fire and the adsorption power of the harmful gas is greater, but the coating layer It is preferable not to exceed 0.8 mm because cracks are generated and the appearance is not good.

상기한 제조공정에 의하여 제조된 코팅제의 효능을 실험하기 위하여, 스치로폼의 표면에 코팅액을 0.05∼0.8mm의 두께로 코팅한후, 열기를 근접시켜 연소되는 상태가 표 1 과 같다.In order to test the efficacy of the coating agent prepared by the above-described manufacturing process, after coating the coating liquid to the thickness of 0.05 ~ 0.8mm on the surface of the styrofoam, the state of combustion by close to the heat is shown in Table 1.

본 발명은 표 1 에서와 같이, 코팅층의 두께가 클수록 연기발생이 적으며, 발화시간이 지연될수록 연기발생량이 증가된다. 때문에 발화초기에 유해가스의 발생량을 줄이기 위하여는 코팅층의 두께를 크게 코팅되는 것이 바람직하며, 발화후 일정시간 경과후 시간이 지날수록 유해가스의 발생이 증가된다.In the present invention, as shown in Table 1, the greater the thickness of the coating layer, the less smoke generation, and the delayed ignition time increases the smoke generation amount. Therefore, in order to reduce the amount of harmful gas generated in the early stage of ignition, it is preferable to coat the thickness of the coating layer largely, and after a certain time after ignition, the generation of harmful gas increases.

상기한 바와 같이, 본 발명은 건축내장재인 스치로폼 표면에 코팅처리하는 것으로서, 화재발생시 코팅제에 함유된 불연성제에 의하여 연소가 지연될 뿐 아니라, 유해가스의 발생이 최소로 되므로, 화재를 초기에 진압할 수 있는 시간을 확보할 수 있을 뿐 아니라, 유독가스에 인한 인명피해를 최소로 할 수 있는 것이다.As described above, the present invention is a coating treatment on the surface of Styrofoam, which is a building interior material, and in case of a fire, not only the combustion is delayed by the nonflammable agent contained in the coating agent, but also the generation of harmful gases is minimized, so that the fire is suppressed at the initial stage. Not only can you have the time to do it, but you can also minimize the casualties caused by toxic gases.

즉, 스치로폼이 발화되기 시작하면, 표면에 코팅된 코팅제가 용해되면서 불연성제가 발화부위에 부착되어 산소의 공급을 차단시키므로 연소속도가 지연되는 효과가 있다.In other words, when the styrofoam starts to ignite, the coating agent coated on the surface is dissolved, and thus a nonflammable agent is attached to the ignition site to block the supply of oxygen, thereby delaying the combustion speed.

또한, 스치로폼 연소될때에 발생되는 유독가스가 다공질의 분말화된 불연성제에 흡착되므로서 유독가스의 발생이 최대한 억제되기 때문에 화재발생시 초기에 유독가스에 의한 인명피해를 방지할 수 있는 효과가 있는 것이다.In addition, since the toxic gas generated when the styrofoam is burned is adsorbed by the porous powdered incombustibles, the generation of the toxic gas is suppressed as much as possible, thereby preventing the human injury caused by the toxic gas at the initial stage of the fire. .

본 발명은 스치로폼의 형상에 구애받지 않고 모든 제품에 코팅처리할 수 있을 뿐 아니라, 기존의 설치된 가연성 스치로폼 표면에 간단히 도포하여 난연성 재료로 변환시킬 수 있는 것이다.The present invention can be applied to all products irrespective of the shape of the styrofoam, and can be simply applied to the existing installed flammable styrofoam surface to be converted into a flame retardant material.

또한, 본 발명은 코팅액이 처리된 표면이 투명 또는 백색으로 유지되므로 기존의 스치로폼 외형의 미감을 크게 해치지 않으면서 간단하게 코팅하여 효과를 배가시킬 수 있는 유익한 발명인 것이다.In addition, the present invention is a beneficial invention that can double the effect by simply coating the coating liquid treated surface without maintaining a great aesthetic appearance of the existing styrofoam because it is maintained in a transparent or white.
