Description
본 발명은 EPS 발포체의 코팅법에 의한 난연 스티로폼 제조에 있어서, 물을 최소한으로 사용하여,부족한 난연제를 보충하기 위하여, EPS 발포체의 코팅공정 에, 난연파우더 투입공정을 부가하여, 건조시간을 단축하는 동시에 난연성능을 향상시키는 건조시간 단축 및 난연성능 향상 스티로폼 제조방법에 관한 것이다. In the present invention, in the manufacture of flame retardant styrofoam by the EPS foam coating method, in order to minimize the use of water and supplement the insufficient flame retardant, a flame retardant powder input process is added to the EPS foam coating process to shorten the drying time. At the same time, it relates to a method for manufacturing styrofoam that reduces drying time and improves flame retardancy to improve flame retardancy.
일반적으로 스티로폼이라고 불리는 EPS(expandable polystyrene, 발포폴리스티렌)발포폼재는 단열성이 우수하고 가격이 저렴하므로 건축물의 단열재 또는 샌드위치패널의 심재로 널리 사용된다. EPS (expandable polystyrene), commonly called Styrofoam, is widely used as a building insulation material or a core material for sandwich panels because it has excellent insulation properties and is inexpensive.
그러나 스티로폼보드는 열에 약하여 화재시 단시간에 녹아내리므로, 스티로폼 보드가 심재로 사용된 샌드위치패널로 축조된 건축물은 화재시건축물이 단시간에 붕괴되며, 유독가스도 발생되는 단점이 있다. However, since the Styrofoam board is weak against heat and melts in a short time in the event of a fire, buildings built with sandwich panels using the Styrofoam board as a core material have the disadvantage that the building collapses in a short time in case of fire, and toxic gases are also generated.
한편, 경우에 따라서는 난연제 코팅과정을 여러 번 반복하여 난연층이 상대적으로 두껍게 형성된 제품이 제안되기도 하나, 이러한 제품은 반복적인 코팅과정 때문에 코스트가 높고, 공정이 복잡하여 생산성이 크게 저하되는 단점이 있다. On the other hand, in some cases, a product with a relatively thick flame retardant layer formed by repeating the flame retardant coating process several times is proposed, but such a product has the disadvantage of high cost due to the repetitive coating process and greatly reduced productivity due to the complicated process. there is.
또 압력을 가하거나 스티로폼 판재에 침봉등을 이용 핀홀(Pinhole)을 만들어 난연성 향상 물질을 판재의 내부까지 침투시켜 난연성을 향상시키기도 하지만 건조공정등이 복잡하여 생산성이 크게 저하된다. In addition, the flame retardancy is improved by applying pressure or making a pinhole in the Styrofoam plate by infiltrating the flame retardant improving material into the inside of the plate, but the drying process is complicated and productivity is greatly reduced.
또한, 난연만의 문제점에 입각하여 글라스울과 같이 내화성이 강한 소재를 보드로 사용되기도 하는데, 이와 같은 글라스울은 시공또는 해체시 비산문제로 작업자에게 산업재해로 이어지는 폐단이 있어 사용을 자제하고 있는 추세이다. In addition, based on the problem of flame retardancy, a material with strong fire resistance, such as glass wool, is sometimes used as a board. Such glass wool has a problem of scattering during construction or dismantling, which leads to industrial accidents for workers, so those who refrain from using it It is a trend.
한편, 새로운 난연소재의 개발과 공정개발로 난연성능이 향상된 난연스티로폼의 제조가 가능해져 일반화 되었다. On the other hand, the development of new flame retardant materials and process development has made it possible to manufacture flame retardant styrofoam with improved flame retardant performance, which has become common.
이와 같은 종래의 난연 스티로폼 제조방법을 살펴보면, 스티로폼용 발포폴리스티렌 원료(EPS)를 1차 발포 시킨(EPS발포비드,EPS발포립) 후, 이러한 발포립을 코팅기에 다수 종류의 난연소재, 접착Binder,물, 용제 등의 물질이 포함되어 있는 복합 난연액과 함께 투입한다. 이에, 코팅기에서 발포립표면에 복합난연액 코팅처리가 되면, 1차,2차 건조기를 거치도록 하여 건조단계를 시행한 후 싸이로(Silo)에 저장후 성형기에서 성형 난연스티로폼을 얻는 방법이 사용된다. Looking at such a conventional flame-retardant styrofoam manufacturing method, after primary foaming of expanded polystyrene raw material (EPS) for styrofoam (EPS foam beads, EPS foam lips), these foam lips are coated with a number of types of flame retardant materials, adhesive binders, It is injected together with the complex flame retardant liquid containing substances such as water and solvent. Therefore, when the composite flame retardant liquid coating is applied to the surface of the foamed grains in the coating machine, a method of obtaining molded flame retardant styrofoam in a molding machine after performing a drying step by going through the first and second dryers and storing in a silo is used. do.
이러한 기존의 제조방법의 경우, 불에 잘타지 않도록 하기 위해, 발포비드에 난연제를 충분히 도포하여 난연기능을 향상시키기 위하여, 상기 발포비드를 기준으로 동일한 중량의 난연제를 도포하는 방법을 사용하고 있다. In the case of this conventional manufacturing method, in order to improve the flame retardant function by sufficiently applying the flame retardant to the foam beads in order not to burn well, a method of applying the same weight of the flame retardant based on the foam beads is used.
이러한 기존의 제조방법의 문제점은 많은 중량의 난연제를 포함하기 위하여 상기 난연제는 물 또는 용제에 혼합한 난연액을 필요로 하므로, 상기 난연제의 중량이 증가할 수록 액체성상의 물 또는 용제의 중량도 증가하게 되므로, 제조된 발포비드를 건조하는 건조공정에서 상기 물 또는 용제의 액체성분을 모두 건조하여야 하는 건조시간이 매우 증가되어서, 제조시간이 불필요하게 증가되며, 건조공정으로 인한 비용이 증가되는 문제점이 있는 것이다. The problem of the conventional manufacturing method is that the flame retardant requires a flame retardant liquid mixed with water or a solvent to contain a large amount of the flame retardant. As the weight of the flame retardant increases, the weight of the liquid water or solvent also increases. Therefore, in the drying process of drying the manufactured foam beads, the drying time for drying all the liquid components of the water or solvent is greatly increased, so the manufacturing time is unnecessarily increased and the cost due to the drying process is increased. There is.
보다 구체적으로는, 원하는 설정된 난연성능의 스티로폼 제조를 위해서는 종래에는 난연액을 EPS 중량대비 200wt%정도를 투입할때에, 상대적으로 스티로폼을 가볍기 때문에 접착코팅도 어렵고 다음 공정의 건조공정에서 통상적인 작업때의 100wt% 때 보다, 많은량의 물을 증발시켜야 하는 문제점이 있는 것이다. More specifically, in order to manufacture Styrofoam with the desired flame retardant performance, conventionally, when about 200 wt% of the flame retardant liquid is added to the weight of EPS, it is difficult to apply adhesive coating because the Styrofoam is relatively light, and it is a common task in the drying process of the next process. There is a problem in that a large amount of water must be evaporated compared to the case of 100 wt% of the time.
또한, 종래에는 난연액 100wt% 씩 2회 코팅해야 하므로, 복잡한 공정과 생산성, EPS 블록화의 어려움등이 발생하는 문제점이 있는 것이다. In addition, in the prior art, since 100 wt% of the flame retardant solution should be coated twice, there are problems in that complex processes, productivity, and difficulties in EPS blocking occur.
본 발명은 상기와 같은 문제를 해결하기 위해 안출된 것으로서, 본 발명의 목적은 일반화된 기존에 습식난연스티로폼 제조방법에서, 물 또는 용제가 사용되는 다양한 난연제에서 물 또는 용제의 액체성상을 줄이고, 건조단계의 공정을 줄여서 건조시간을 단축시키는 동시에, 최종 공정에서 상기 난연액에 포함된 난연제의 부족한 중량을 보충하기 위하여, 상기 난연제의 외주연에 별도로 난연파우더를 균일하게 코팅하여 난연기능이 향상된 난연성능 향상 스티로폼 제조방법을 제공하는데 있다. The present invention has been made to solve the above problems, and an object of the present invention is to reduce the liquid properties of water or solvent in various flame retardants in which water or solvent is used in the conventional wet flame retardant styrofoam manufacturing method, and dry In order to shorten the drying time by reducing the step process and at the same time to compensate for the insufficient weight of the flame retardant contained in the flame retardant liquid in the final process, flame retardant performance is improved by uniformly coating the flame retardant powder separately on the outer periphery of the flame retardant. It is to provide a method for manufacturing improved styrofoam.

종래에는 난연액을 EPS 중량대비 200wt%정도를 투입할때에, 원하는 설정된 난연성능의 스티로폼 제조를 위해서는 상대적으로 스티로폼을 가볍기 때문에 접착코팅도 어렵고 다음 공정의 건조공정에서 통상적인 작업때의 100wt% 때 보다, 많은량의 물을 증발시켜야 하며, 난연액 100wt% 씩 2회 코팅해야 하므로, 복잡한 공정과 생산성, EPS 블록화의 어려움등이 발생하는 문제점이 있는 것이다. Conventionally, when about 200wt% of the flame retardant liquid is injected relative to the weight of EPS, in order to manufacture Styrofoam with the desired flame retardant performance, it is difficult to apply adhesive coating because the Styrofoam is relatively light, and when 100wt% of normal work in the drying process of the next process Rather, since a large amount of water must be evaporated and 100 wt% of the flame retardant must be coated twice, there are problems in complex processes, productivity, and difficulties in EPS blocking.
